Abstract

The invention provides an individual suspension front axle with a virtual master pin structure, relating to a vehicle part. The individual suspension front axle comprises an airbag assembly, an upper swing arm, a steering knuckle, a lower swing arm and a brake assembly, wherein the airbag assembly is directly mounted on the upper swing arm; the upper swing arm is connected with the upper end of the steering knuckle through a suspension spherical hinge assembly; the middle part of the steering knuckle is directly connected with the brake assembly; and the lower end of the steering knuckle is connected with the lower swing arm through the suspension spherical hinge assembly. The individual suspension front axle provided by the invention has favorable running smoothness and control stability, the steering knuckle plays a role of a traditional support arm, the suspension spherical hinge assembly is used instead of a master pin, and parts, such as the support arm, the master pin, dowels, an adjusting washer, a conical roller bearing and an oil seal, are omitted, so that the structure is greatly simplified, the cost and weight are reduced, the machining accuracy and assembly difficulty are reduced, the swing vibration is small, the automatic return effect is good, and the popularization and use are facilitated.

Description

technical field

[0001] The invention relates to an auto part, in particular to an independent suspension front axle with a virtual kingpin structure. Background technique

[0002] Traditional disconnected independent suspension front axle (eg Figure 13-Figure 14 ), the support arm 15 is used to connect the steering knuckle 17 with the kingpin 16 and support the movement of the wheel. Compared with the non-disconnected front axle, due to the reduction of its unsprung mass, the height of the center of mass of the automobile engine is reduced, and at the same time The two wheels move independently of each other without affecting each other, and the ride comfort and handling stability of the car are greatly improved. However, the traditional independent suspension front axle still has the following problems: (1) The support arm structure is complicated, the processing requirements are high, and the quality is low. Heavy, high cost of parts; (2) The installation process of the c...
