This invention relates to a suspension system for a self-steering vehicle.

が、これによると磯構が複線となるため重量が増加し、
コストも高くつくという難点があった。In the conventional two-axle trunnion type suspension system, the rear two axles do not have a steering function, so the turning radius of the vehicle tends to be large, and side force is generated when the vehicle turns, which increases tire wear. Another drawback is that excessive internal stress is generated in each part of the suspension system. There has also been a proposal (Special Publication No. 5O-25691) in which the rear two axles are linked to the steering operation of the front axle, but this would result in an increase in weight as the rock structure would become a double track.
The problem was that the cost was high.

ることである。The present invention has been made in order to eliminate the drawbacks of the prior art described above, and its purpose is to provide a trunnion type suspension for supporting two rear axles of a vehicle with a pair of lower torque rods on each side. In the device, a large inclination angle is given to the lower torque rod, and a rubber member is interposed between the rear two-wheel axle housing and the leaf spring. The second method is to use the difference in the swing angle of the lower torque rod on the left and right sides of the vehicle to force the rear two axles to perform a self-steering function with an extremely simple force configuration. The objective is to improve vehicle maneuverability by reducing the dynamic turning radius of the vehicle, reduce tire wear by reducing side force, and improve durability by reducing internal stress in the suspension system. . Another objective is to enable a lighter design of the suspension system by reducing internal stresses.

特徴とするものである。In short, the present invention provides a trunnion-type suspension system that includes a pair of lower torque rods on the left and right sides and supports two rear axles of a vehicle, in which at least the pair of lower torque rods are positioned at respective mounting joints to the trunnion shaft. , the mounting joints for the first rear shaft and the second rear shaft are mounted at lower positions, and the axle housing of the first moving shaft and one end of the leaf spring are fixed via a rubber member, The axle housing of the rear second shaft and the other end of the leaf spring are fixed via a rubber member, so that when the vehicle tilts from side to side due to turning, the swing angle of the lower torque rod changes. Taking advantage of the fact that the left and right sides of the vehicle are 1, the first rear axle and the second rear axle are moved closer to each other on one side of the vehicle and separated from each other on the other side to perform self-steering. It is characterized in that the rubber member is configured to absorb the displacement of the rear two axes that occurs.

The attachment joint portions 2b to the first apprentice shaft 4 and the second rear shaft 5 are each mounted at a lower position. This also applies to the pair of upper torque rods 6 attached to the center of the vehicle. That is, the lower torque rod 2 has a steep slope in the front and rear direction from the attachment joint 2a for the trunnion shaft 3 toward the attachment joint 2a for the rear first shaft 4 and the rear second shaft 5. , the angle α of each lower torque rod 2 is set to α<1800.

The structure is such that self-steering is performed by bringing them close to each other on one side and separating them from each other on the opposite side, and the displacement of the rear two shafts 4 and 5 caused by the self-steering is absorbed by the rubber member R.

て互いに離間する。The present invention is constructed as described above, and its operation will be explained below. As shown in FIG. 4, for example, when a vehicle attempts to turn to the left as indicated by arrow A, the centrifugal force acts in the right direction in the direction of travel, so that the vehicle tilts to the right due to the resultant force of the vehicle's own weight. Then, as shown in FIG. 2, a large downward force FD acts on the right side chassis frame 8 of the trunnion type suspension T and the right side of the trunnion shaft 3, so that the lower torque rod 2 on the right side is attached to the trunnion shaft 3. The joint part 2a moves downward by a large distance, and the lower torque rod 2 swings by an angle Δα from the solid line state to the virtual line state, and the angle α is large.As a result, the mounting joint part 2b moves forward. As shown in FIG. 4, the first rear shaft 4 is pushed forward and the second rear shaft 5 is pushed backward, and they are separated from each other.

。On the other hand, on the left side of the vehicle, the trunnion shaft 3 is lifted upward by the upward force FU, so the third
As shown in the figure, as the angle α of the lower torque rod 2 becomes smaller, the lower torque rod swings by Δα from the solid line state to the virtual line state. As a result, the joint part 2b moves by a distance t in the front and rear directions, and the distance CL is not short, and as shown in FIG. 4, the rear first shaft 4 moves rearward,
The rear second shafts 5 are each drawn forward and approach each other.

Displacement occurs between the shaft 4, the rear second shaft 5, and the leaf spring 9, but this is absorbed by the rubber member R, so that no excessive force is applied. Furthermore, when the vehicle turns to the right, self-steering is performed by the opposite effect to the above, and in either case, the vehicle can turn smoothly.

設計を可能にし得る効果がある。Since the present invention is constructed and operates as described above, in a trunnion-type suspension system that supports two rear axles of a vehicle, which is equipped with a pair of lower torque rods on each side, the lower torque rods have a large size. By providing a tilt angle and inserting a rubber member between the rear two axle axle housings and the leaf springs, when the vehicle tilts while turning, the swing angle of the lower torque rod on the left and right sides of the vehicle is reduced. By utilizing the fact that the rear two axes are different, it is possible to make the rear two axles have a self-steering function with an extremely simple configuration, and as a result, the rear two
The dynamic turning radius of the axle vehicle is reduced to improve the maneuverability of the vehicle, and the reduction in side force reduces wear on the side tires, thereby improving their durability. In addition, internal stress is also reduced, which has the effect of making it possible to design the suspension system to be lighter.
