Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stabilizer device that suppresses roll and pitch of a vehicle.

[0002]

[Prior art]

 2. Description of the Related Art There is known a stabilizer device in which left and right axles of a vehicle are formed in a generally U-shape, and portions extending parallel to the vehicle are rotatably supported by the vehicle and both ends thereof are connected to the left and right axles, respectively.

[0003]

[Problems to be solved by the device]

 However, the known stabilizer device is effective only for reducing the roll of the vehicle, but it is not a technique that is expected to reduce the pitching.

Therefore, an object of the present invention is to provide a stabilizer device capable of simultaneously preventing rolling and pitching.

[0005]

[Means for Solving the Problems]

 According to the present invention, there are provided U-shaped front stabilizers and rear stabilizers respectively connected to front and rear axles of a vehicle, the front stabilizers being divided into a first portion and a second portion, The rear stabilizer is divided into a third part and a fourth part, and an intermediate link mechanism is provided in the middle of the vehicle, and the first part of the stabilizer is connected to the fourth part via the first rod and the intermediate link mechanism. And the second portion of the stabilizer is connected to the third rod of the third portion via the second rod and the intermediate link mechanism.

[0006]

[Action]

 In the stabilizer device configured as described above, since the stabilizers of the wheels that are symmetrical to each other with respect to the center of the vehicle are connected, the rear wheels that cross the front wheels are related to the front wheels. Go up and down in the direction.

Therefore, when the vehicle body is rolled, the front and rear wheels outside the roll move toward the vehicle body (the direction in which the vehicle body sinks), and the inner front and rear wheels also move toward the vehicle body in the same manner, so the roll can be prevented.

Further, for example, during braking, the rear wheels at the position where the front side of the vehicle intersects when the front side of the vehicle sinks will also similarly sink, so that pitching can be prevented.

[0009]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, a first portion 1 of the front stabilizer is rotatably mounted by a bearing 3 provided on a vehicle body, and a second portion 2 is similarly mounted by a bearing 3 and is also referred to as a first portion. They are coaxially and rotatably connected to each other.

The other end, which is bent at a substantially right angle, is pivotally attached to an axle 21, and a left front wheel FL and a right front wheel FR are attached to the axle 21.

Also referring to FIG. 2, a lever 17 is fixed to the first portion and a lever 18 is fixed to the second portion.

The rear portion of the vehicle is provided with a third portion 4, a fourth portion 5, a bearing 6 for pivotally supporting them on the vehicle body, levers 19 and 20, an axle 22, a left rear wheel RL, and a right rear wheel RR. It has the same structure as the section.

As shown in FIG. 3, an intermediate link portion 7 which is an intermediate link mechanism is provided in the intermediate portion of the vehicle. The intermediate link portion 7 is attached to the brackets 8 and 8 mounted on the vehicle body by levers 10a, A collar 10 to which 10b is fixed is rotatably attached by a shaft 9, and a collar 12 positioned by a spacer 11 is rotatably provided on the outer periphery of the collar 10.

Further, levers 12 a and 12 b are fixed to the collar 12.

The levers 17 and 12b are connected to the first rod 13, the levers 18 and 10a are connected to the second rod 14, the levers 19 and 10b are connected to the third rod 15, and the levers 20 and 12a are connected to each other. Are pivotally connected to the fourth rods 16, respectively.

Therefore, for example, if the left front wheel FL moves in the A direction, the first rod 13 moves in the B direction by the lever 17 of the first portion, and the fourth rod 16 moves in the B direction via the levers 12b and 12a. The fourth portion moves the right rear wheel RR in the C direction via the lever 20.

The relationship between the right front wheel FR and the left rear wheel RL is the same.

Further, when the left and right front wheels move in the directions A and C, the left and right rear wheels similarly move in the directions A and C. Therefore, when the front part is lowered during braking, the rear part is also lowered.

Further, the intermediate link mechanism may be omitted, and the first rod 13 and the fourth rod 16, and the second rod 14 and the third rod 15 may be one rod each.

The operation is similar to that of the first embodiment.

[0022]

[Effect of device]

 Since the present invention is configured as described above, rolling of the vehicle can be suppressed during cornering, and nose dive of the vehicle can be suppressed during braking to provide a flat ride comfort.

Therefore, the riding comfort can be improved without impairing the steering stability.
