Description

Vehicle tie rod sub-assembly device {Vehicle tie rod sub-assembly device}

The present invention relates to a tie-rod sub-assembly device for a vehicle, and more particularly, to a tie-rod sub-assembly device coupled to a steering device of a vehicle.

In general, a steering device of a vehicle includes a steering wheel, a steering gear frame, and a link mechanism.

The steering gear frame increases the operating force by decelerating the rotation of the steering shaft, converts the motion direction of the operating mechanism and transmits it to the link mechanism, and the link mechanism transmits the operation of the gear mechanism to the front wheels and corrects the relationship between the left and right wheels. support

The steering gear frame is subdivided according to the type of steering gear, but is roughly divided into a bolt and nut type and a rack and pinion type.

The rack and pinion type is mainly used for small cars and has a structure in which a pinion is installed at the end of a steering shaft to engage with a rack.

When the pinion rotates, the rack moves laterally and the steering wheel moves along with the knuckle through the tie rod serve connected to the rack and both ends.

The tie rod serve connects the left and right knuckle arms and transmits the operation of the third arm to the other knuckle arm to accurately maintain the relative position of the left and right wheels. It is made of drawn steel pipe and tie rod ends are combined at both ends because it receives compressive or tensile force due to the offset of the front wheel or the impact of the road surface when driving.

This tie-rod sub fixes a cylinder equipped with a bi-directional rod on a workbench. Left and right tie rod ends assembled with ball joints and bellows corresponding to each rod are coupled.

Conventionally, a skilled worker fixes a cylinder on a workbench, mounts the left and right tie rod ends on a moving table provided on both sides of the cylinder, and directly measures the distance between the tie rod end and both rods of the cylinder. By moving the moving table, the tie rod end and the rod were coupled.

However, this assembly work has a disadvantage in that errors may occur depending on the skill level of the operator and the work efficiency is low.
