Abstract

A universal joint includes a tube having a hollow shape; a slip bush inserted into the tube; and a shaft assembled with the tube through the slip bush, wherein the slip bush includes power transmission parts, which are arranged along an circumferential surface of the slip bush in an axial direction and have pins positioned at centers of the power transmission parts and supports supporting both ends of each pin, and elastic parts, which are arranged along the circumferential surface of the slip bush while being spaced from the power transmission parts and have a section with a C-shape, which is formed in such a manner that a side portion is cut out in the axial direction. Therefore, strength and rigidity are improved, even when twist is generated in the universal joint, so that clearance and noise due to abrasion, pressing, etc. can be minimized.

Description

technical field [0001] The invention relates to a universal joint, in particular to a sliding bush provided with a power transmission part of the universal joint. Background technique [0002] In a steering device of a vehicle, if a driver turns a steering wheel in a predetermined direction, a steering shaft connected to the steering wheel turns correspondingly. This steering shaft transmits the rotational force to a gearbox, which includes rack-pinion gears, and passes through a universal joint. At this time, the gearbox converts the rotational motion of the steering shaft into a linear motion through the rack-and-pinion gear, which is transmitted to the gear rod. The gear rod can transmit force to the tie rod connected to the steering knuckle of the wheel, so as to change the driving direction of the vehicle. [0003] More specifically, the shaft between the steering shaft and the gearbox has a structure in which an input rod and an output rod are connected to each other ...
