Abstract

The invention relates to the field of automobile components, in particular to an automobile steering system. An intelligent steering compensation device of a commercial automobile comprises a steering middle shaft, a second shaft, a steering compensation execution unit and a steering output shaft. A gear pair is formed by the steering output shaft and a second shaft output gear through an output shaft gear fixedly installed at one end and a gear pair is formed by a middle shaft gear and a second shaft input gear. Worm wheel teeth are arranged on the end face of the second shaft output gear. A worm controlled through a driving mechanism is arranged in the steering compensation execution unit. The worm wheel teeth and the worm are matched to form a worm wheel and worm mechanism. The driving mechanism is controlled by and connected with a steering compensation control unit. According to the intelligent steering compensation device, understeer is reduced or oversteer is relieved through forward-steering and backward-steering compensation according to the traveling state of the automobile; the control sensitivity of the automobile is improved through forward-steering and backward-steering compensation, the driving pleasure is improved, or the comfort of automobile driving is improved through reduction of the steering sensitivity.

Description

technical field [0001] The invention relates to the field of automobile parts, in particular to an automobile steering system. Background technique [0002] The steering system used in existing passenger cars and light commercial vehicles is mainly composed of a steering wheel, a steering wheel shaft, an intermediate shaft, a steering gear input shaft, a steering gear and a steering tie rod. When the system is working, the driver turns the steering wheel, the steering action is transmitted to the intermediate shaft through the universal joint, and then transmitted to the input shaft of the steering gear through the universal joint. The left and right pulling action realizes the deflection of the steering wheel and turns. [0003] The existing steering system is a mechanical structure, which can realize the steering function linearly, and lacks the function of intelligently assisting the driver to realize the driving intention. Contents of the invention [0004] The techn...
