Description
Technical Field
The invention belongs to the technical field of electric vehicle chassis, and particularly relates to an independent steering system with a steering motor arranged on equal-length double-trailing-arm suspension steering knuckles.
Background
The trailing arm type independent suspension has the advantages that when the wheel jumps, the camber angle and the wheel track of the wheel are basically unchanged, and meanwhile, the trailing arm type independent suspension occupies small lateral space of a vehicle body, and is beneficial to reducing the vehicle width.
When the single-trailing-arm independent suspension is used on a steering wheel, a large part of steering moment is decomposed into harmful moment which can overturn the wheel. When the double-trailing-arm independent suspension adopts the equal-length double trailing arms, the wheel positioning parameters can be kept unchanged, and when the caster angle of the kingpin is set to be zero when the caster angle of the kingpin is used for steering wheels, the steering torque can be completely used for steering.
The servo motor with high power density, high efficiency and small volume is developed rapidly at present, the technology is mature, and the output torque can meet the requirements of most of wheel steering torque after the speed reduction and torque increase of the speed reduction mechanism. The integrated encoder can be used for accurately controlling the steering angle of the wheels. The output shaft of the motor can be designed into various connecting structures according to the requirements.
