Abstract

The invention discloses a chassis with a four-wheel steering function. The chassis comprises a rear steering axle. The rear steering axle comprises a rear wheel steering drive axle and a rear wheel steering reversal mechanism. The rear wheel steering drive axle comprises an axle body, a left steering knuckle, a right steering knuckle, two steering knuckle arms, two trapezoid arms and a rear steering tie rod. The left steering knuckle and the right steering knuckle are arranged at the two ends of the axle body respectively. The two steering knuckle arms are fixed to the left steering knuckle and the right steering knuckle respectively. The two trapezoid arms are fixed to the left steering knuckle and the right steering knuckle respectively. The rear steering tie rod is connected with the two trapezoid arms. The left steering knuckle and the right steering knuckle are fixedly connected with hubs of two rear wheels respectively. The rear wheel steering reversal mechanism comprises a hydraulic reversal cylinder, a motor, a rear wheel steering machine, a steering rocker arm and a rear wheel steering pull rod. The motor, the rear wheel steering machine, the steering rocker arm and the rear wheel steering pull rod are sequentially connected. The steering knuckle arm connected with the rear wheel steering pull rod moves to drive the rear wheels to steer, and the other steering knuckle arm is connected with a piston rod of the hydraulic reversal cylinder. The chassis achieves the four-wheel steering function of a commercial vehicle and meanwhile is simple in structure and small in control difficulty.

Description

technical field [0001] The invention relates to the technical field of automobile chassis structure, in particular to a chassis with four-wheel steering function. Background technique [0002] As a revolutionary technology in the field of automobile chassis control, four-wheel steering can greatly improve the handling stability and maneuverability of automobiles. At present, four-wheel steering technology has been applied to some small vehicles, but it is rarely involved in the field of commercial vehicles in China. Four-wheel steering technology is of great significance for improving the maneuverability and handling stability of commercial vehicles, especially in the field of special commercial vehicles. There are already a number of four-wheel steering special vehicles on sale abroad, mainly involving the fields of fire protection and military use. And there is no commercial vehicle chassis supply with four-wheel steering function in China. Contents of the invention ...
