Liftable wheel assembly

Abstract

The invention discloses a liftable wheel assembly, which relates to the technical field of vehicle manufacturing, and comprises a wheel, a hub motor, brake calipers, a steering mechanism and a damping mechanism, the damping mechanism is arranged at the bottom of the steering mechanism, a stator end of the hub motor is connected with the damping mechanism, the rotor end of the hub motor is connected with the wheel, and the brake calipers are arranged on the two sides of a brake pad on the hub motor. The wheel assembly is installed on an automobile chassis, an automobile steering wheel transmission encoder outputs steering signals to a controller in an automobile, the controller outputs corresponding signals through calculation to control servo motors at the tops of the wheel assemblies to drive speed reducers, and then driving gears are driven to drive an outer ring of a slewing bearing to rotate. And each wheel can independently rotate by 360 degrees. A protective shell encapsulates a pivotal bearing and a driving gear in a cavity through the oil seal, the pivotal bearing is protected against interference of other objects, and lubricating oil can be added through the oil injection hole to protect and maintain the part and dissipate heat of the part.

Description

technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a liftable wheel assembly. Background technique [0002] At present, the steering of the vehicle is realized by the steering gear. The mechanical steering system, the electric power steering system, the hydraulic power steering system, etc. all use the steering gear to realize the steering. The input shaft will transmit the steering intention from the steering wheel, and the signal will be transmitted through the sensor. To the booster motor, the booster motor and the reduction mechanism finally convert the torque into the lateral displacement thrust of the rack, and the rack drives the wheels to turn. The steering gear in the above steering mechanism is usually assembled from gear input shafts, racks, outer tie rods, steering tie rods, steering gear housings and other parts. The parts of the rack and pinion mechanism are manufactured with high precision and assembl...

AI Technical Summary

Problems solved by technology

The steering gear in the above steering mechanism is usually assembled from gear input shafts, racks, outer tie rods, steering tie rods, steering gear housings and other parts. The parts of the rack and pinion mechanism are manufactured with high precision and assembly precision, and the manufacturing cost is high. In order to assemble the rack and pinion structure, it is necessary to design an installation housing. The housing is large in size and heavy in weight, which makes it difficult to arrange on the vehicle chassis. The heavy mass increases the weight of the vehicle, which seriously affects the battery life of the electric vehicle, and cannot realize the rotation of each wheel. 360 degree independent rotation
