Abstract

The invention relates to a four-wheeled independent steering mechanism and a working method and belongs to the field of automobiles. The mechanism comprises a stepping motor, a speed reducer, a speed reducing gear pair, a steering transmission shaft, a cushioning spring, a steering connecting mechanism and the like. A steering torque of the motor is transmitted to the steering transmission shaft through a speed reducing mechanism, and the steering torque is provided for a wheel assembly through a ball contact steering knuckle. According to the structure, a steering motor and the speed reducer are integrated into the steering connecting mechanism. The four-wheeled independent steering mechanism is compact in structure, novel in steering transmission and flexible to steer; the cushioning spring is utilized, so that the comfort and stability of vehicle driving are improved; and meanwhile, the four-wheeled independent steering mechanism has important meanings on research, development and design of a four-wheeled independent driving, independent braking and independent steering electric wheel automobile.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a four-wheel independent steering mechanism and a working method. Background technique [0002] With the continuous development of new energy vehicles and smart vehicles mainly based on electric vehicles, more and more intelligent integration technologies are applied to the field of electric vehicles. The traditional vehicle steering system has gradually been unable to adapt to its complex mechanical structure. The development needs of increasingly integrated and intelligent control. [0003] At present, the existing four-wheel independent steering technology in China mostly uses an independent steering motor to drive the steering shaft through the reduction mechanism, and directly drives the steering kingpin to achieve a wide range of steering angle deflection. For example, Chinese patent document CN103072627A discloses a four-wheel independent steering electric chassis, the structur...
