Radial retaining ring type vehicle steer-by-wire steering wheel device

Abstract

The invention discloses a radial baffle ring type vehicle steer-by-wire steering wheel device. The device aims at accurately detecting the rotation angle of a steering wheel, providing adjustable and suitable road feeling for a driver, changing working modes under different working conditions, and adjusting the steering wheel to complete all-steering rotation loops. A central shaft is installed inside a bearing pedestal of an upper end cover and a lower end cover of a box body through a bearing and is sleeved with baffle rings in sequence, the innermost baffle ring is fixedly installed on the central shaft, an angular displacement sensor is installed on the lower surface of the upper end cover of the box body, an electromagnetic coil is installed on the lower surface of the lower end cover of the box body, a damping disc is fixedly installed at the lower end of the central shaft, a motor is fixedly installed on a motor support, the motor support is fixedly installed on the box body, a transmission lead screw is installed on the support through the bearing, a transmission nut is in transmission fit with the transmission lead screw, and the transmission lead screw is fixedly connected with an output shaft of the motor through a coupler. The radial baffle ring type vehicle steer-by-wire steering wheel device is applicable to vehicle steer-by-wire steering wheels.

Description
