Embodiment Construction

[0026] The present invention is described in detail below in conjunction with accompanying drawing:

[0027] The wheel-side comprehensive driving and steering traveling mechanism of the present invention is designed for the wheel-side driving electric vehicle that realizes the wheel-side independent steering of the ±90° wire control, and performs the driving, transmission, driving, steering and braking of the wheels. Redesign, integrate the traditional driving, transmission, and braking systems into the wheel components for wheel drive and braking, and integrate the traditional steering system into the middle of the suspension, that is, the traditional steering trapezoid is replaced by the steering-by-wire steering system and steering components. The traditional suspension system is replaced by a suspension assembly that integrates the steering assembly and the wheel assembly. The axis of the kingpin in the wheel-side comprehensive drive and steering running gear is vertical to...

Abstract

The invention discloses an automobile traveling mechanism wheel hub comprehensively drive and turning, aiming to solve the problems of easy fatigue damage, low vehicle stability, and the like. the automobile traveling mechanism comprises a wheel assembly, a suspension assembly and a turning assembly, wherein the turning assembly comprises a worm wheel bracket (14), a worm wheel (15), a worm (23),a turning motor (24), a coupler (25) and a double-fork type transmission assembly, wherein the double-fork type transmission assembly consists of an upper fork arm (7), a lower fork arm (22), a low friction hinge, an upper spherical hinge (5) and a lower spherical hinge (6); the suspension assembly comprises a shock absorber sleeve barrel, a spiral spring (2), a shock absorber (3), a lower springseat (4) and an upper spring seat (27); the wheel assembly comprises a wheel (11), a hub motor (12), a shaft head (13) and a wheel bracket (10); the worm wheel bracket (14) is sleeved in the middle ofthe shock absorber sleeve barrel and is horizontally fixed on an automobile frame, and a wheel bracket (10) is fixedly connected with the lower end surface of the shock absorber sleeve barrel.

Description

technical field [0001] The invention relates to a running mechanism on a wheel-side driven electric vehicle using wire-controlled independent steering, more specifically, it relates to a vehicle running mechanism with integrated wheel-side driving and steering. Background technique [0002] The chassis of a traditional car is composed of transmission, driving, steering and braking systems, which can guarantee the performance of the car during normal driving. The linkage limits the wheel angle range. Therefore, when the vehicle moves in a relatively narrow place, the driver needs to do more complicated operations, which affects the passability of the car and the efficiency of vehicle transportation to a large extent. Therefore, with the rapid development of automobile technology and electronic technology, the application of drive-by-wire, steering, and braking technologies in automobiles is becoming more and more extensive, and there is a tendency to integrate them at the wh...
