Description

Steering knuckle

Technical Field

The application relates to the field of automobile parts, in particular to a steering knuckle.

Background

At present, the knuckle is an important part in an automobile front axle system, the knuckle is used for enabling an automobile to stably run and transmit a running direction, and the main functions of the knuckle are as follows: the front load of the automobile is transmitted and borne, and the front wheels are supported and driven to rotate around the main pin, so that the automobile is steered.

In the related art, the knuckle includes the knuckle main part, is used for knuckle wall, brake braking installation department, the fast tester installation department of wheel, bumper shock absorber installation department and the lower swing arm linking arm be connected with the tie rod that turns to, sets up the steering hole that supplies the axle shaft sleeve to wear to establish on the knuckle. When the automobile steers, the steering tie rod drives the steering knuckle wall to rotate, so that the half shaft sleeve drives the hub to rotate.

In view of the above-mentioned related technologies, the inventor believes that in the above-mentioned technical solution, in the process of steering the automobile, the steering angle of the semi-axle sleeve needs to be adjusted through the knuckle, the power arm of the force applied by the knuckle to the semi-axle sleeve is in direct proportion to the thickness of the knuckle, and the thickness of the knuckle is limited due to the limited space occupied by the automobile front axle system, and the power arm of the force applied by the steering knuckle to the semi-axle sleeve is limited, so that under the condition of applying the same torque to the semi-axle sleeve, the steering knuckle needs to apply larger force to the semi-axle sleeve, thereby having higher requirements on the maximum bending stress of the knuckle, and the maximum bending stress of the knuckle is limited due to the material of the knuckle, when the automobile makes a sharp turn, the rotating joint is required to apply larger torque to the semi-axis sleeve, so that the steering joint is easy to break.

SUMMERY OF THE UTILITY MODEL
