Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stabilizer control device that selectively controls rolls and pitches generated according to the running condition of a vehicle.

[0002]

[Prior Art]

 Conventionally, a case part is fixed to one of the stabilizers divided by a torsion bar, and a rod part that rotates in the case part is fixed to the other part of the stabilizer, and one or the other of the oil chambers separated in the case is fixed. A stabilizer control device has been proposed in which the case portion and the rod portion are rotationally biased in a forward or reverse direction in a coupled state by sending pressure oil.

Therefore, according to this, when a roll is generated during turning while the vehicle is traveling, one of the oil chambers described above is configured to generate a torsional elastic force in the stabilizer in a direction to suppress the roll. Pressure oil is supplied.

[0004]

[Problems to be solved by the device]

 However, since the conventional stabilizer control device has the hydraulic control structure as described above, the system configuration is complicated and expensive, and the energy consumption is increased because the hydraulic power source is moved, and the hydraulic power source is stopped. Then, the roll reducing function of the stabilizer is lost, so that there is a problem that a fail safe means including a hydraulic sealing mechanism in this case is required.

Further, there is a problem that the structure of the case and the rod portion becomes complicated, and in addition, precision processing is required in the oil leakage prevention mechanism portion and the like.

The present invention has been made in view of the above-mentioned conventional problems, and does not require expensive and large-scale equipment such as a pump and a hydraulic power source, and is mechanically simple and inexpensive. The purpose is to obtain a control device.

[0007]

[Means for Solving the Problems]

 A stabilizer control device according to the present invention is attached to a first stabilizer and a second stabilizer, one ends of which are connected to respective suspensions of left and right wheels, and the other ends of the first stabilizer and the second stabilizer so as to face each other. A first bevel gear and a second bevel gear, and a third bevel gear and a fourth bevel gear which are coaxially arranged between the first bevel gear and the second bevel gear and meshed with the first bevel gear and the second bevel gear; Thereby rotatably supporting the first motor for urging the first stabilizer and the second stabilizer in opposite directions, the third bevel gear, and the fourth bevel gear, and fixing the first motor. The rotation of the gear member and the first motor is locked, and the second motor is used to lock the rotation. By normal and reverse driven through the pinion meshing the Ya member thereto, but the first stabilizer and the second stabilizer was so that by rotationally urged in the same direction.

[0008]

[Action]

 A first motor according to the present invention twists and rotates the first stabilizer and the second stabilizer in opposite directions via a third bevel gear and a fourth bevel gear to prevent rolls, and when the first motor is locked, the first motor and the second stabilizer are rotated. The two motors transmit the rotation to the first stabilizer and the second stabilizer via the gear member, and these are twisted and rotated in the same direction to each other so that pitch prevention can be achieved.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 2, 1,1 'are left and right wheels, 2,2' are suspension arms of these wheels 1,1 ', 3 and 3 are first stabilizers each having one end connected to each suspension arm 2,2'. And a second stabilizer, 4 is a stabilizer control device for connecting one end of each of the first stabilizer 3 and the second stabilizer 3 ′, and 5 and 5 ′ are vertical portions of the linear portions of the first stabilizer 3 and the second stabilizer 3 ′. A supporting member slidably supporting the power cylinder 6, a power cylinder for steering, both ends of which are attached to the knuckle arms 7, 7 '.

FIG. 1 is a specific configuration diagram of the stabilizer control device 4. Reference numerals 8 and 8'are the first and second bevel gears fixed to the opposite ends of the stabilizers 3 and 3 ', and 9,9' are interposed between the first and second bevel gears 8 and 8 '. A third bevel gear and a fourth bevel gear that mesh with each other, and these are connected to the rotary shaft 11 of the first motor 10 in a direction orthogonal to the stabilizers 3 and 3 ′.

A gear member 12 is rotatable around the second stabilizer 3 ′ around the second stabilizer 3 ′. The first motor 10 is installed on a mounting plate 13 integrated with the gear member 12. A pair of bearing members 14 are provided on the gear member 12 and rotatably support the rotating shaft 11.

Reference numeral 15 is a pinion that meshes with the gear 12 a of the gear member 12, and the pinion 15 is attached to a rotary shaft 17 of a second motor 16 fixed to the vehicle.

Next, the operation will be described. First, the case of roll control will be described. When a roll is generated while the vehicle is running, a control current for controlling the roll is supplied to the first motor 10.

At this time, the rotation of the second motor 16 is locked and stopped. Therefore, the first motor 10 receives the control current and drives the third bevel gear 9 and the fourth bevel gear 9'in the forward rotation direction or the reverse rotation direction at a predetermined rotation speed with a predetermined torque.

Therefore, the first bevel gear 8 and the second bevel gear 8 ′ meshing with the respective bevel gears 9 and 9 ′ relatively rotate in opposite directions as shown in FIG. 3. As a result, the first stabilizer 3 and the second stabilizer 3'whose ends are connected to the bevel gears 8 and 8'are twisted in directions opposite to each other, and the torsional elastic force is controlled, which occurs. It functions to reduce the roll.

Next, pitch control will be described. In this case, the rotation of the first motor 10 is locked, and the second motor 16 is supplied with the control current for controlling the generated pitch.

Therefore, the rotation lock of the first motor 10 locks all the rotation of the first to fourth bevel gears 8, 8 ′, 9, 9 ′, and the rotation of the second motor 16 causes the gears to rotate. It is driven from the member 12 through the pinion 15 in the forward rotation direction or the reverse rotation direction.

Then, this driving force is transmitted to the first stabilizer 3 and the first stabilizer 3 via the first motor 10, the rotating shaft 11, the third and fourth bevel gears 9 and 9 ′ and the first and second bevel gears 8 and 8 ′. When transmitted to the second stabilizer 3 ', they are simultaneously twisted in the same direction as shown in FIG.

Therefore, receiving the torsional force, the repulsive force accumulated in the first and second stabilizers 3 and 3 ′ functions to suppress the pitch.

Thus, the roll and pitch can be effectively suppressed in accordance with the desired control command, and the posture of the vehicle body can be actively stabilized.

[0021]

[Effect of the device]

 As described above, according to the present invention, the first stabilizer and the second stabilizer, one ends of which are connected to the suspensions of the left and right wheels, and the other ends of the first stabilizer and the second stabilizer, respectively, face each other. A first bevel gear and a second bevel gear that are attached, and a third bevel gear and a fourth bevel gear which are coaxially arranged between the first bevel gear and the second bevel gear and meshed with the first bevel gear and the second bevel gear. When driven, it rotatably supports the first motor that urges the first stabilizer and the second stabilizer to rotate in opposite directions, the third bevel gear and the fourth bevel gear, and fixes the first motor. The rotation of the gear member and the first motor is locked, and the second motor serves to lock the gear portion. The first and second stabilizers are rotationally biased in the same direction by driving the forward and reverse rotations through a pinion that meshes with this, so there is a risk of oil leakage and large energy consumption. It is possible to securely and cleanly control the roll and pitch of the vehicle safely and cleanly without using large and expensive equipment such as pumps, tanks, and switching valves. Also, lock the motor when the power is off. Thus, the effect that the normal function as the stabilizer can be surely achieved without providing a special fail-safe mechanism is obtained.
