Embodiment 1

[0024] An electronic steering device includes an electric double-screw steering gear and an electronic steering wheel device.

[0025] Such as figure 1 As shown: the electric double-helix steering gear includes a motor 1, a left lead ball screw 2, a right lead ball screw 3, a left ball nut cylinder 4, a right ball nut cylinder 5, a steering position Hall sensor 6, a first Permanent magnet 7, left steering ball head 8, right steering ball head 9, steering fixed support 10.

[0026] The motor is provided with a rotor, and the left lead ball screw and the right lead ball screw are respectively located at the left and right ends of the motor and are coaxially and rigidly connected with the rotor. The left ball nut barrel and the right ball nut barrel are sleeved on the left lead ball screw and the right lead ball screw respectively; when the motor drives the left lead ball screw and the right lead ball screw to rotate, the left ball nut barrel, right The ball nut barrel makes li...

Embodiment 2

[0034] The difference between Embodiment 2 and Embodiment 1 is that the first permanent magnet in Embodiment 2 is installed on the outer wall of the right ball nut barrel, the steering position Hall sensor is installed on the inner wall of the steering fixed bracket, and the steering position Hall sensor The position corresponds to the position of the first permanent magnet.

Abstract

The invention relates to the field of automobile steering systems, and discloses an electronic steering device. The electronic steering device comprises an electric dual-screw-type steering engine and an electronic steering wheel device. The electric dual-screw-type steering engine comprises a motor, a left lead ball screw, a right lead ball screw, a left ball nut cylinder, a right ball nut cylinder, a steering position Hall sensor, a first permanent magnet, a left steering bulb, a right steering bulb and a steering fixing support. The electronic steering wheel device comprises a directional rotating disc, a fixed disc, a steering resistance adjustor, a fixing hollow support, a steering wheel touch sensor, a steering position indicator, a second permanent magnet and a phase-changing Hall sensor. The electronic steering device has the advantages that manual phase changing and manual speed rotating of the steering motor are achieved, the steering wheel and the steering engine are in non-mechanical connection, easy and precise control steering is achieved, the steering wheel is not affected by uneven impact of a road, the steering wheel has no gap, and control steering is stable.

Description

technical field [0001] The invention relates to the field of automobile steering systems, in particular to an electronic steering device. Background technique [0002] The electronic steering device is used to control the steering of the car wheels. [0003] The Chinese patent application number CN201410320359.7 discloses a steering gear of an automobile steering system, a steering system of an automobile, and an automobile. steering torque; and a steering actuator for driving steering of the steered wheels. Wherein, the steering gear further includes a transmission ratio adjustment device, through which the steering input shaft is in transmission connection with the steering actuator. Through the solution of the invention, the car can realize rapid steering with a smaller steering wheel angle at low speed, and can realize safe steering with a larger steering wheel angle at high speed, so as to maintain the stability and safety of the car. [0004] The Chinese patent appl...
