AI Technical Summary

Technical Problem

In existing vehicle wheel end structures, the independent arrangement of the suspension system, steering system and braking system results in dispersed structural relationships, long load paths and complex local stresses. Especially under complex working conditions, it is difficult to balance motion guidance, lateral stability and load transfer rationality.

Method used

The active suspension system, steering system, and braking system are integrated between the vehicle body and the wheels. The wheel end support, guidance, and adjustment structure is formed by trapezoidal link groups, dual active damping components, and guide links. Dynamic adjustment is achieved by using hydraulic actuators and sensing elements.

Benefits of technology

It improves the guiding stability, lateral restraint, and load transfer rationality of the wheel end area, enhancing the vehicle's motion stability and structural coordination under complex working conditions.

Abstract

The application provides a vehicle corner module, belonging to the technical field of corner modules, which is arranged between a vehicle body and a wheel, and comprises a main suspension system, a steering system and a braking system. The main suspension system comprises a first main damping assembly, a second main damping assembly, a guide connecting rod, a coil spring and a trapezoidal connecting rod set. The trapezoidal connecting rod set is formed by first, second, third and fourth connecting rods which are connected in a head-to-tail mode, and the middle part of the second connecting rod is connected with a wheel end connecting part and serves as a transverse constraint rod. The steering system and the braking system are arranged in the wheel adjacent area and cooperate with the wheel end area. The corner module can realize suspension active adjustment, steering execution and braking execution in the same wheel end area, and improve the guiding stability, transverse constraint ability and load transmission rationality of the wheel end area.
