Abstract

The invention discloses a linear nonlinear steer-by-wire steering gear, which comprises an inner-outer pull rod and ball head assembly, a small hoop, a corrugated pipe, a large hoop, an input shaft and pinion assembly, a steering gear shell, a stator, steering gear mounting brackets, a controller and wiring harness assembly and a rack and electronic solenoid rotor assembly, wherein the rack and electronic solenoid rotor assembly comprises a rack and an electronic solenoid; the inner-outer pull rod and ball head assembly comprises a steering gear inner pull rod and an inner ball head located atthe right tail end of the steering gear inner pull rod; the inner-outer pull rod and ball head assembly is connected with the rack through the inner ball head; the corrugated pipe is respectively fixed on the steering gear inner pull rod and the steering gear shell through the small hoop and the large hoop; the input shaft and pinion assembly is fixed through the steering gear shell and is in matched transmission with the rack; the stator is in threaded connection with the steering gear shell and located on one side of the input shaft and pinion assembly; the steering gear shell comprises twosteering gear mounting brackets located on two sides of the stator; and the controller and wiring harness assembly is integrated on the steering gear shell.

Description

Technical field: [0001] The invention relates to a wire-control chassis system of an intelligent driving vehicle, in particular to a linear nonlinear steering-by-wire steering device. Background technique: [0002] The current rack and pinion electric power steering used in passenger cars is mainly divided into column assist type, pinion assist type, double pinion type, and ball screw type according to the location and structure of the assist. [0003] The column-assisted motor is installed on the steering column. The torque of the motor is amplified through the worm gear and input to the input shaft of the steering gear through the steering column. The force on the column is relatively large, which leads to the limitation of the input torque. The pipe column is suitable for miniature cars with small loads. And because the motor is arranged in the cockpit, the noise generated easily causes the driver to complain. [0004] In the electric power steering gear of several othe...
