Abstract

The invention relates to a connecting structure of a guide arm and a support and relates to a commercial vehicle suspension system. The connecting structure comprises a support, a guide arm assembly and a bolt. The support comprises a first lug seat and a second lug seat. The guide arm assembly comprises a lug rolling part; the lug rolling part is arranged between the first lug seat and the secondlug seat; a locking part is arranged on the outer side surface of the second lug seat, a lock sleeve is arranged in the locking part, and the locking part locks the lock sleeve in a circumferential direction; the bolt penetrates in from the first lug seat and passes through the lug rolling part, the second lug seat penetrates out from the lock sleeve, and the nut is screwed to screw the bolt to be attached to the lock sleeve, so that the guide arm assembly is hinged to the support; and the reliability of connection between the guide arm and the support is improved through cooperative use of the locking part and the lock sleeve.

Description

technical field [0001] The invention relates to a commercial vehicle suspension system, in particular to a connection structure between a guide arm and a bracket. Background technique [0002] At present, the locking structure of the leaf spring guide arm and the guide arm bracket is locked by bolts; this structure generates axial pretightening force and locking bolt clamping force through the nuts matched with the bolts to ensure the clamping of the bracket and the guide arm. [0003] The current locking structure mainly has the following problems: that is, the rigidity of the bracket is large, and it is difficult to clamp; it is difficult to clamp only by the pre-tightening force of the nut; High force, easy to damage. Contents of the invention [0004] In view of the above problems, the present invention provides a connection structure between the guide arm and the bracket, which can effectively solve the problems existing in the existing connection structure and impro...
