Ring-type vehicle steer-by-wire steering wheel device

Abstract

The invention discloses a baffle-ring-type vehicle line-control steering-wheel device, and aims to accurately detect the rotation angle of a steering-wheel, provide adjustable and proper road sense for a driver, and adjust the number of turnings for the steering-wheel to complete turning by changing working patterns under different working conditions. A central shaft is mounted in a bearing support of a box body and a lower end cover through a bearing; a baffle ring is fixedly mounted on the central shaft; an angle limiting ring is mounted on the central shaft in a movably fitting manner; an input hollow shaft of an angular misalignment sensor is fixedly connected with the central shaft; the casing of the angular misalignment sensor is fixedly mounted on the lower end cover of the box body; a chuck is fixedly mounted at the lower end of the central shaft; a motor is fixedly mounted on a motor bracket; the motor bracket is fixedly connected with the box body fix; a transmission worm is mounted on the bracket through a bearing; a transmission nut is mounted on the transmission screw rod in a matched manner; the transmission worm is fixedly connected with an output shaft of the motor through a coupler. The baffle-ring-type vehicle line-control steering-wheel device, provided by the invention, can be used as a line-control steering-wheel for the vehicle.

Description

technical field [0001] The utility model relates to a vehicle steering device, in particular to a retaining ring type vehicle wire-controlled steering wheel device. Background technique [0002] The function of the steering system is to control the driving direction of the vehicle. The system should be able to keep the vehicle running in a straight line stably and flexibly change the driving direction according to the requirements. The basic requirements for the steering system are light and flexible operation, stable and reliable operation, and economical and durable use. The steering performance is an important factor to ensure the safe driving of the vehicle, reduce the labor intensity of the driver, and improve the work productivity. The steering system is a key assembly that determines vehicle safety and operating efficiency. [0003] The vehicle steer-by-wire steering wheel device with the patent application number 201310025567.X can change the working mode under diff...
