Abstract

The invention relates to a steering under-drive shaft assembly, especially being used for an automobile steering mechanism and belonging to the technical field of auto spare parts. The steering under-drive shaft assembly mainly adopts a lower universal joint fork to be connected with a shaft universal joint fork, wherein the shaft universal joint fork is connected with an under-drive shaft in a welding way; the under-drive shaft is connected with a coupling disc in the welding way; the coupling disc is connected with a rubber disk through short rivets; the rubber disk is connected with a middle universal joint fork through bolts, gaskets, and flange face locking nuts; the middle universal joint fork is connected with the universal joint forks through a universal joint crossing shaft; a positioning pin is arranged on the nose of the under-drive shaft; a positioning hole is arranged in the coupling disc; and a rubber positioning sleeve is arranged in the positioning hole of the coupling disc. The steering under-drive shaft assembly can ensure the axiality of the composite structure of the under-drive shaft, plays a role in floatation positioning, thereby eliminating the defect of frequent abnormal sound resulting from rigid contact, and is remarkable in shock absorption effect, thereby improving the safety performance of vehicle travelling.

Description

technical field [0001] The invention relates to a steering lower transmission shaft assembly, in particular to an automobile steering mechanism, and belongs to the technical field of automobile accessories. Background technique [0002] At present, the steering mechanism of an automobile is mainly composed of a steering wheel, a steering shaft assembly, a steering column assembly, a lower steering shaft assembly, and a steering machine. The steering lower transmission shaft assembly is an important part of the automobile steering mechanism. It is connected to the upper steering shaft assembly and the lower steering gear. Its function is mainly to transmit steering torque. The steering lower transmission shaft assembly is mainly connected by the lower universal joint yoke and the shaft universal joint yoke, the shaft universal joint yoke and the lower transmission shaft with positioning pins are connected by welding, and the lower transmission shaft with positioning pins The...
