Steering knuckle assembly and front-wheel steering system

Abstract

The invention provides a steering knuckle assembly. The steering assembly comprises a steering knuckle body, an upper fork arm connecting body, a lower fork arm connecting body, a brake caliper firstconnecting body and a brake caliper second connecting body, wherein a first end of the upper fork arm connecting body is arranged on the steering knuckle body, and a vertical connecting hole A is formed in a second end of the upper fork arm connecting body; a first end of the lower fork arm connecting body is connected to the steering knuckle body, and a vertical connecting hole B is formed in thesecond end of the lower fork arm connecting body; and a front inclination angle gamma formed by a connecting line between the center of the vertical connecting hole A and the center of the vertical connecting hole B and a plumb line of an automobile is 5 degrees - 13 degrees, and a contact point between an extension line of a connection line and the ground is 40 mm-50 mm away from a ground supporting distance d of a tire contact center, wherein the connection line is between the center of the vertical connecting hole A and the center of the vertical connecting hole B. The steering knuckle assembly IS conductive to promote the stability and operability of a automobile steering system and the safety of drivers and passengers.

Description

technical field [0001] The invention relates to the technical field of automobile steering systems, in particular to a steering knuckle assembly and a front wheel steering system. Background technique [0002] In the existing technology, such as figure 1 As shown, the steering kingpin of the conventional automobile steering system is arranged in the way of caster, inclination, offset and trailing distance. The natural state of the front wheel train is displayed in a "eight" posture, and the front frame is the lowest point at this time. , the friction between the tire and the ground is small. [0003] like figure 2 As shown, when the steering system of the car is equipped with the pull rod and the steering machine, the body is raised and the posture is normal. At this time, the left and right tires maintain balance by pushing or pulling each other (the front steering machine pushes each other, and the rear wheel pushes each other). Steering machines pull each other, and t...

Problems solved by technology

[0004] At present, the problem of automatic steering correction is solved by matching the power steering system. Although the effect is very good, it will also lead to an increase in the cost of the vehicle and energy consumption during driving. However, the current wheel system of conventional vehicles is not assembled with the steering rod and steering gear. When connected, the whole vehicle cannot walk. If there is a sudden failure on one side during driving, it is very likely to cause an accident
