Embodiment Construction

[0024] The present invention is described in detail below in conjunction with accompanying drawing:

[0025] refer to figure 1 , figure 2 and image 3 , the present invention integrates the wire-controlled wheel independent steering actuator 6 inside the wheel to realize the function of independent rotation of the left and right steering wheels or four wheels, so that the vehicle can complete some special driving functions such as four-wheel steering and spot steering. working conditions. The wheel-by-wire independent steering actuator 6 can improve the steering maneuverability, driving safety and handling stability of the vehicle.

[0026] The wheel-by-wire independent steering actuator 6 of the present invention includes a steering motor and a photoelectric encoder combination unit 22, a steering gear, a torque sensor 26, an upper kingpin 15, a lower kingpin 12, and two kingpins with the same structure that slide Bearing 14 and kingpin thrust bearing 13, wherein the div...

Abstract

The invention discloses a wire controlled wheel independent steering execution mechanism and a wheel assembly. The wire controlled wheel independent steering execution mechanism comprises a steering gear, a lower master pin, a master pin thrust bearing, two master pin sliding bearings with the same structure, an upper master pin, a steering motor and photoelectric encoder combined unit, and a torque sensor. The output shaft of the steering motor is connected with the input shaft of the steering gear by a coupler, the output shaft of the steering gear is in key connection with one end of the torque sensor through the upper master pin, the other end of the torque sensor is in key connection with the other end of the torque sensor, the lower end of the upper master pin is sleeved with the master pin sliding bearing and is in dynamic fit with the master pin sliding bearing, and the lower master pin is sleeved with the master pin sliding bearing and the master pin thrust bearing, which have the same structure, in turn from top down, and is in dynamic fit with the master pin sliding bearing and the master thrust bearing. The wheel assembly comprises a tire, a hub, an annual hub motor, a brake, an annular brake disc and the line controlled wheel independent steering executing mechanism. The annular hub motor consists of an annular hub motor outer rotor, a large-diameter cone roller bearing, a steering joint and a motor inner stator component.

Description

technical field [0001] The invention relates to a steering actuator applied to automobile wheels, more specifically, it relates to a wire-controlled wheel independent steering actuator that can realize independent rotation of each wheel and the wire-controlled wheel independent steering actuator wheel assembly. Background technique [0002] Traditional steering systems (mechanical, hydraulic or electric power steering systems) can ensure that the car turns according to the driver's will, but because of its fixed steering ratio, the car's steering response characteristics vary with vehicle speed and steering wheel angle. Therefore, the driver must perform some operation compensation for the change of the steering response characteristic of the vehicle, which affects the handling stability of the vehicle to a large extent and increases the driver's burden. In addition, the movement of the left and right wheels in the traditional steering system is in the same direction and th...
