Abstract

PURPOSE:To prevent torsion of a leaf spring and to enlarge the steering amount by supporting both ends of an accel housing on a leaf spring capable of freely sliding in the longitudinal direction in such a manner as to freely slide in the direction of the width and freely oscillate, and stretching a Watt link over right and left support members and the accel housing. CONSTITUTION:An accellation housing 4 is supported in such a manner as to freely slide in the axial direction on a support member 9 rotatably installed on the middle portion of leaf springs 1, 6 by a bolt 10. A rod 12 is connected between a ball joint 113 of the top portion of a bracket 9 and a lever 111 supported on a top pin 114 of a differential unit 5 to form a Watt link 11. The trailing end of the leaf spring 6 is supported in such a manner as to oscillate by a shackle 7, and the leading end thereof is supported in such a manner as to slide in the longitudinal direction by an actuator 8. By this arrangement, the torsion of the leaf spring can be prevented and the steering amount can be increased.

Conventionally, in vehicles that support the axle housing with leaf springs, a rear wheel steering device that steers the rear wheels in response to the steering of the front wheels has been used to move the rear axle between both rear wheels by sliding the leaf spring in the longitudinal direction of the vehicle body. There has been known a device in which the rear wheels are steered by rotating the wheels between the midpoints (see Japanese Patent Laid-Open Publication No. 77285/1985).

In the conventional rear wheel steering device described above, the leaf spring is driven parallel to the longitudinal direction of the vehicle body, so when the rear wheels are steered, the rear axle is rotated between the midpoints of both rear wheels. Since the joint between the spring and the axle housing rotates and draws an arc trajectory centered on the midpoint between the rear wheels, the position of the joint between the leaf spring and the axle housing is lower than the mounting position on the vehicle body frame. Since the steering wheel moves inward in the vehicle width direction, and both ends of the leaf spring do not move, the leaf spring is twisted, making it impossible to increase the steering angle amount, resulting in increased metal fatigue of the leaf spring.

In order to achieve the above object, the vehicle rear wheel steering device of the present invention slides a pair of left and right leaf springs that support an axle housing in the longitudinal direction of the vehicle body so as to move in opposite directions. In a four-wheel steered vehicle that steers a wheel, a pair of left and right axle housings are connected to the left and right leaf springs so that both ends of the axle housing can slide in the vehicle width direction relative to the left and right leaf springs and can swing. The axle housing is equipped with a support member, an actuator that slides the leaf spring in the longitudinal direction of the vehicle body according to predetermined conditions, and a one link provided to span the left and right support members and the axle housing.

[Operation] The vehicle rear wheel steering system of the present invention configured as described above slides in the vehicle body longitudinal direction so as to move the left and right leaf springs in opposite directions by operating the actuator. As the leaf spring slides, the axle housing is rotated inward in the vehicle width direction via the support member, and the angle formed between the leaf spring and the axle housing changes, causing the vehicle width of the axle housing to change. Although the distance between the directional center and the supporting member changes,
Both ends of the axle housing slide in the vehicle width direction, and the Watt link follows, allowing smooth steering of the rear wheels.
