Embodiment 1

[0020] combine figure 1 and figure 2 , a suspension mechanism driven by in-wheel motors, including a driving mechanism 1 and a steering mechanism 2. The driving mechanism 1 includes a tire 3, a hub 4, a hub motor 5 and a brake pad 6. The tire 3 is installed on the hub 4 through a tire dismounting machine. The hub motor 5 and the side plate of the hub 4 are fixedly connected by bolts. The hub motor 5 shaft shoulders are fixedly connected by bolts.

[0021] The steering mechanism 2 includes a main shaft, a motor base 12, a worm screw 13, a worm wheel 14, a car body connector 15, a motor 18 and a rotating bearing mechanism, and the car body connecting member 15, the worm wheel 14 and the rotating bearing mechanism are successively arranged on the On the main shaft, two ends of the motor seat 12 are provided with two side plates, and the motor 18 is fixed on the outer wall of one side plate by bolts. The other end of the worm 13 is rotationally connected with the other side pl...

Abstract

The invention discloses a suspension fork mechanism based on wheel hub motor driving. The suspension fork mechanism comprises a tire, a wheel hub, a wheel hub motor, a brake block, a lower half shaft, springs, an upper half shaft, a bearing seat, a bearing, a motor seat, a worm, a worm wheel, a vehicle body connecting piece, a first locking nut, a second locking nut and a motor. According to the suspension fork mechanism disclosed by the invention, a steering mechanism and a driving mechanism are integrally designed; according to a vehicle where the suspension fork mechanisms are mounted, four wheels can be steered at the same time; the steering angle is arbitrary, movements of lateral translation, in-place autorotation and the like can be realized; and the suspension fork mechanism is simple in structure, light and flexible in movement and high in practicality.

Description

technical field [0001] The invention belongs to the field of vehicles, and in particular relates to a suspension mechanism driven by a hub motor. Background technique [0002] In recent years, with the rapid development of communication technology and Internet technology, the field of all-electric driverless vehicles has emerged as the times require, and major car companies, including universities, have invested in research. Three-axis all-electric drive unmanned vehicles are generally driven by hub motors and powered by batteries. Compared with traditional vehicles, the unsprung mass is increased and the driving mode is changed. Based on the above characteristics, the handling stability of the vehicle has become the focus of research. In order to improve its handling performance, four-wheel steering technology is one of the most common chassis control technologies to improve vehicle handling stability. With the advancement of computer control technology, the development a...
