Technical Field

The invention belongs to the technical field of automobile balanced suspensions, and relates to a plate spring sliding plate seat, in particular to a split plate spring sliding plate seat for a balanced suspension.

Background

If two axles (e.g., the center axle and the rear axle of a three-axle vehicle) are mounted at both ends of the stabilizer bar and the center of the stabilizer bar is hingedly connected to the frame, raising one axle lowers the other axle. Moreover, because the two arms of the balancing rod are equal in length, the vertical loads of the two axles are equal under any condition, and the suspension condition of individual wheels cannot be generated. This type of suspension, which ensures equal vertical loading of the wheels of the middle and rear axles, is called a balanced suspension.

The automobile balanced suspension can well distribute the force on the front wheel and the rear wheel evenly, and therefore the automobile balanced suspension is widely applied. The plate spring sliding plate seat is used for fixing two ends of a balanced suspension, while the plate spring sliding plate seat in the existing balanced suspension for engineering mostly adopts an integral structure, the plate spring sliding plate seat is seriously abraded by a plate spring in the actual use process, and how to prolong the service life of the plate spring sliding plate seat is generally to enhance the wear resistance of the plate spring sliding plate seat; when the abrasion is serious, all parts connected with the plate spring sliding plate seat need to be detached to replace the whole plate spring sliding plate seat, the replacement is difficult, and the spare part cost is high.

Through retrieval, as disclosed in chinese patent literature, a split type leaf spring slide plate seat [ application number: CN 201320820396.5; publication No.: CN203713456U ]. The split type plate spring sliding plate seat comprises a plate spring sliding plate support and a wear-resisting plate which are fixedly connected. In the use, when the wear-resisting plate is seriously worn by the plate spring, only the wear-resisting plate needs to be replaced, the original plate spring sliding plate support and the pin can be continuously used, the replacement process is simple, and the spare part cost is low. Although this arrangement causes the leaf spring to rub against the wear plate, the wear is still significant, increasing replacement costs.
