Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement in the mount rubber structure of a change lever for an automobile.

(Prior Art) Conventionally, as the above-mentioned mount rubber structure, the ball joint of the change lever 1 has been used, for example, as in the structure shown in FIG. 1a and FIG. The inner metal fitting 3 and the outer metal fitting 4 that support the ball joint part 2 are airtightly connected by an annular mount rubber 5 in a horizontal plane passing through the center of the ball joint part 2. There is one consisting of thick (hard) parts 6, 6 that strongly resist rocking in the shift direction, and thin (soft) parts 7, 7 that weakly resist rocking in the shift direction. .

However, the mount rubber 5 has a problem in that it is necessary to bake and mold the inner and outer edges of the mount rubber 5 on both the inner metal fitting 3 and the outer metal fitting 4, respectively, which increases the manufacturing cost.

(Purpose of the invention) The present invention was made in view of the above-mentioned conventional problems.The mount rubber is positioned and press-fitted between the outer surface of the inner metal fitting and the recessed part of the inner surface of the outer metal fitting, and is then bonded. The purpose of this is to reduce manufacturing costs by making it so that it can be installed with just one step, eliminating the need for conventional baking molding.

(Structure of the device) Therefore, in the present invention, a pair of recesses with open bottoms are formed on both inner surfaces of the outer metal fitting in the selection direction, and the pair of recesses of the outer metal fitting and the outer surface of the inner metal fitting are formed. The mount rubber, which is press-fitted from the lower opening, is bonded between the mount rubber and the mount rubber.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, the floor panel 11 of the passenger compartment
A change control unit 13 is attached to an insertion hole 12 provided in the change control unit 13, and a control rod 15 of an outside transmission is connected to the lower end of a change lever 14 of the change control unit 13.

The change control unit 13 has a rectangular base plate 16, and the center of the base plate 16 is stamped out using a press or the like to integrally form an annular large-diameter outer metal fitting 17, and bolts 1 are attached to the four corners of the base plate 16.
8, . bolt 1
The board 16 is attached to the floor panel 11 by screwing nuts into the nuts 8, . . . , 18.

An annular small-diameter inner fitting 21 is placed on the outer fitting 17, and the inner surfaces of the recessed parts 17a, 17a of the outer fitting 17 and the outer surfaces of the bulging parts 21a, 21a of the inner fitting 21 are aligned in the select direction of the change lever 14. They are connected by mount rubbers 23, 23 that are hard in the direction of the shift and soft in the shift direction.

As shown in detail in FIGS. 3, 4, and 5, the recesses 17a, 17a of the outer fitting 17 are
It is formed by opening the lower side of both inner surfaces of the outer metal fitting 17 in the selection direction and punching it out with a press or the like.

Moreover, the bulging parts 21a, 21a of the inner fitting 21 are
In correspondence with the recesses 17a, 17a of the outer metal fitting 17, the inner metal fitting 21 is formed by punching out the inner metal fitting 21 with a press or the like with the outer surfaces on both sides in the selection direction open at the bottom.

Furthermore, square piece-shaped mount rubbers 23, 23
is the width of the recessed part 17a of the outer fitting 17,
17a for positioning in the width direction, and the thickness of the recessed portions 17a, 1
The inner surface of 7a and the bulges 21a, 21a of the inner fitting 21
It is set to be press-fitted between the outer surface of the holder and the outer surface of the holder via adhesives 24, 24.

The depressions 17a, 17a and the bulges 21a, 2
Since the mount rubbers 23, 23 are press-fitted between the inner fitting and the outer fitting 1a, the inner fitting and the outer fitting can be positioned and prevented from moving in the rotational direction.

With the above configuration, while the inner fitting 21 is fitted into the outer fitting 17, the recesses 17a, 17a of the outer fitting 17 and the bulges 21a, 2 of the inner fitting 21 are arranged.
1a, press fit the mount rubbers 23, 23 coated with adhesives 24, 24 on the inner and outer surfaces from the lower open parts of the recesses 17a, 17a, the mount rubbers 23, 23 will be glued and the installation will be completed. I come to do it.

The mount rubbers 23, 23 act hard against the swinging of the change lever 14 because they are solid in the select direction, and are soft in the shift direction because they are hollow, thereby preventing erroneous gear shifting operations.

Although not specifically shown in the drawings, inside the inner fitting 21 there is a holder that supports a ball seat that supports the ball joint portion of the change lever 14.
A compressed spring is fitted between the upper part of the inner metal fitting 21 and an extension bar 29 is connected to the lower bracket of the holder.

Further, a rubber boot is attached to the upper part of the inner metal fitting 21 and the upper part of the outer metal fitting 17, and the inner metal fitting 2
1 and the outer metal fitting 17 to prevent noise from outside the vehicle.
Water and air will be shut off.

Furthermore, it goes without saying that the mount rubber may be in the form of a plate or a molded product that conforms to the shape of the bulge or depression.

(Effects of the invention) As is clear from the above explanation, the invention has the following effects:
The mount rubber is positioned between a pair of recesses on the inner surface of the outer metal fitting and the outer surface of the inner metal fitting, and is press-fitted and adhesively attached. There is no need to bake and mold the rubber, and the installation process is simple and reliable, reducing manufacturing costs.
