It is mounted on the vehicle body 4 by being screwed into the female screw hole 4b of the mounting portion 4a.

Each friction pad 6 comprises a lining 16 which is in sliding contact with the side surface of the disc rotor 2 and a metal back plate 17 which is joined to the lining 16. Action part 5
The friction pad 6 on the a side is the caliper mounting portion 4 of the vehicle body 4.
The friction pads 6 on the side of the reaction portion 5b are disposed between the a and 4a, respectively, and are disposed between the pad mounting concave portions 5g, and the two hanger pins 18, which are hung between the action portion 5a and the reaction portion 5b, A pad spring 19 is movably suspended in the disc axial direction at 18, and is elastically urged toward the disc center by a pad spring 19 attached to both the hanger pins 18 and 18 and the ceiling opening 10.

The rigid member 15 is attached to the caliper mounting portions 4a, 4a of the vehicle body 4 together with the above-mentioned vehicle body mounting portions 15a, 15a fixed by the slide pin 3 and the reaction portion 5b on the side opposite to the disc rotor side. Two supporting portions 15b having an L-shaped cross section arranged and two ends of the supporting portion 15b and two vehicle body mounting portions 15a, 15a are connected across the outside of the disc rotor 2 while sandwiching both sides of the bridge portion 5c.

A guide hole 15 is provided at the center of the support portion 15b.
e is formed so as to penetrate in the axial direction of the disk, and the shaft portion 20a of the guide pin 20 projecting from the reaction portion 5b is slidably inserted into the guide hole 15e. Further, a bulging portion 5h bulging toward the side opposite to the disc rotor is provided in the center of the reaction portion 5b, and a through hole 5i is formed through the bulging portion 5h in the disc axial direction, and the disc of the bulging portion 5h is formed. The recess on the rotor side serves as a storage recess 21.

The guide pin 20 described above is a headed pin having a large head 20d at the base end of a shaft portion 20a consisting of a small diameter portion 20b on the tip side and a medium diameter portion 20c on the base end side. The pin 20 has a small-diameter portion protruding from the through hole 5i after the head portion 20d is accommodated in the accommodating concave portion 21 by inserting the medium diameter portion 20c into the through hole 5i and is prevented from coming off by the friction pad 6 on the reaction portion side. 20b is slidably inserted into the guide hole 15e of the rigid member 15, and the tip side of the small diameter portion 20b is projected from the guide hole 15e to the side opposite to the disc rotor. As a result, the reaction portion 5b far away from the slide pins 3 and 3 serving as a support member of the caliper body 5 is guided by the guide pin 20.
Also supported by. By the way, the protrusion amount of the small diameter portion 20b protruding from the guide hole 15e to the side opposite to the disc rotor is
Even if the linings 16 and 16 of the friction pads 6 and 6 are fully worn, the length is such that the fitting state with the guide hole 15e can be maintained.

This embodiment is constructed as described above,
When the hydraulic fluid whose pressure is increased is supplied to the hydraulic pressure chamber 12 of the caliper body 5 by the braking operation of the driver, the hydraulic pressure chamber 12 expands and the piston 11 advances through the cylinder hole 8 toward the opening portion, and the piston 11 pushes the friction pad 6 on the action portion side to push the lining 16 of the pad 6 to one side surface of the disc rotor 2. By this reaction, the caliper body 5 moves toward the operation part 5a while the operation part 5a is guided by the slide pins 3 and 3, and the reaction part 5b is guided by the guide pin 20, respectively, and the reaction part 5b is the friction pad on the reaction part side. 6 is pushed to push the lining 16 of the pad 6 to the other side surface of the disc rotor 2.

On the side surface of the portion 4a, and on the side of the reaction portion 5b, the side surface of the back plate 17 on the disk feeding side is also supported on the side surface of the pad mounting recess 5g. The braking torque is transmitted to the caliper body 5 from the friction pad 6 on the reaction portion side, and the reaction portion 5b tends to be deformed to the disk extension side more than the action portion 5a. The slide fitting of this suppresses this as much as possible.

Thus, the disc brake 1 of this embodiment
Is an integral type in which the slide pins 3 and 3 are directly attached to the caliper mounting portions 4a and 4a of the vehicle body 4, but the rigid member 15 that supports the reaction portion 5b and the guide pin 20 cause the caliper body 5 to move due to braking torque. Since tilting is effectively suppressed, it can be applied to heavy vehicles such as sports cars, race cars, and large vehicles that generate large braking torque. Further, the caliper body 5 can be moved satisfactorily in the disc axial direction, and at the same time, uneven wear of the lining 16 caused by tilting of the caliper body 5 can be suppressed to a minimum.

Further, since the slide pin 3 also serves as the fastening fixing of the caliper mounting portion 4a and the vehicle body mounting portion 15a, the number of parts can be reduced and the number of assembling steps can be reduced, which is economical. In addition, for a light vehicle such as a light vehicle that does not require reinforcement by the rigid member 15 and the guide pin 20 and has a small braking torque, by removing the rigid member 15, the remaining members of the disc brake 1 can be used as they are as the original configuration of the integral type. It can be used and the number of brakes that have been set for each vehicle type can be greatly reduced, resulting in a great economic effect.

Further, the guide pin 20 of this embodiment has the head 2
Since 0d is housed in the housing recess 21 that is recessed in the support portion 15b of the rigid member 15, it is prevented from slipping off to the friction pad 6 on the reaction portion side, so press fitting, screw cutting, welding, etc. for fixing the guide pin 20. The fixing means can be eliminated, and the guide pin 20 and the through hole 5i can be roughly manufactured.

The disc brake 30 shown in FIGS. 4 and 5 is
The second embodiment of the present invention is shown.

It is sandwiched between the friction pads 31,
31 is suspended from the rigid member 15.

The friction pad 31 is constructed by joining a lining 32 and a back plate 33. On the back plate 33,
Hook-shaped ear pieces 33a, 33a are provided on both sides, and projections 33b, 33b for transmitting torque are provided on the back surface, respectively.
In the friction pad 31 on the action portion side, the protrusion 3 for transmitting torque is used.
3b and 33b are fitted into the opening of the piston 11, and in the friction pad 31 on the reaction side, the protrusions 33b and 33b for torque transmission are brought into contact with the torque receiving surfaces 5j and 5j, and the respective ear pieces 33a, 33a is a connecting portion 15c between the bridge portion 5c of the caliper body 5 and the rigid member 15.
It is locked to the outer surface of the connecting portion 15c from between and is movably suspended in the disc axial direction.

A pair of guide holes 15e, 15e are formed through the bearing portion 15b of the rigid member 15 in the disc axial direction, and a through hole 5i is formed in the reaction portion 5b of the caliper body 5 so as to open toward the disc rotor side. A storage recess 21 that is recessed toward the through hole on the disk rotor side of the through hole 5i is continuously provided on the same axis as the respective guide holes 15e. Similarly to the first embodiment, each guide pin 20 receives the head portion 20d in the storage recess 21 by inserting the intermediate diameter portion 20c into the through hole 5i, and the friction pad 31 on the reaction portion side prevents the guide pin 20 from coming off. , A small diameter portion 20b protruding from the through hole 5i
Is slidably inserted into the guide hole 15e of the rigid member 15.

The friction pad 3 is brought into sliding contact with the disc rotor 2.
The braking torques generated at 1 and 31 are supported by the caliper body 5 from the respective torque transmitting projections 33b and 33b through the piston 11 or the torque receiving surfaces 5j and 5j. Further, the braking torque generated in the friction pads 31, 31 is large, and the caliper body 5 is not in contact with the friction pads 31, 31.
When an attempt is made to incline largely in the disc spilling direction integrally with the ears 33 of the friction pads 31 on the disc spilling side.
a respectively abuts and engages with the connecting portion 15c of the rigid member 15.

As a result, the braking torque of the friction pad 31 is supported by both the caliper body 5 and the rigid member 15, and the load on the caliper body 5 is reduced.
While a high braking torque is generated in the disc brake 30, the tilting of the caliper body 5 due to the braking torque can be suppressed extremely small. Further, in this embodiment, the action portion 5b of the caliper body 5 is connected to the two guide pins 20, 20.
Since it is supported with a high rigidity, the tilting of the caliper body 5 due to the braking torque can be further suppressed.

As a modification of the second embodiment, the projections for torque transmission may be eliminated from both friction pads, and all the braking torque may be directly supported by the rigid member. In this case, since the braking torque of the friction pad is hardly applied to the caliper body, it is possible to further suppress the tilting of the caliper body in the disc feeding direction.

The disc brake of the present invention is the above-mentioned first brake.
As described in the second embodiment, the caliper bracket is omitted, and the integral type in which the slide pin is directly attached to the caliper mounting portion of the vehicle body is adopted, but the attachment / detachment of the rigid member reduces braking torque and vehicle weight. It can be applied to different vehicles. Further, in the disc brake using the caliper bracket, it is difficult to support the reaction part side having a large behavior with the caliper bracket on the action part side, but in the present invention, since the reaction part is supported by the rigid member and the guide pin, The tilting of the caliper body can be effectively suppressed. Further, in the caliper bracket type, if the caliper bracket is omitted, it does not function as a disc brake, but the present invention can use the remaining components even in a lightweight vehicle having a small braking torque even if the rigid member is omitted. it can.

The guide pin and the guide hole of the present invention may be provided in the reaction portion of the caliper body and the support portion of the rigid member in an inverse relationship to the first and second embodiments, and the guide pin is press-fitted. Fixing means such as screwing, screwing, welding, and adhesive may be used alone or in combination, and may be directly projected on the reaction portion or the support portion. To fix both the caliper mounting part of the vehicle body and the rigid member body mounting part together by tightening, a set screw separate from the slide pin is screwed directly into the caliper mounting part or the female screw hole of the vehicle body mounting part, or You may use it in combination with a nut.

It can be applied to heavy vehicles such as cars and large vehicles.

In addition, since a rigid member can be removed and used for a light vehicle such as a light vehicle having a small braking torque, the type of disc brake conventionally set for each vehicle type can be greatly reduced, and the economy can be improved. The effect is extremely high. Further, by suppressing the tilting, the caliper body can be moved satisfactorily in the disc axial direction, and at the same time, the uneven wear of the lining due to the tilting of the caliper body can be suppressed as small as possible.
