Abstract

The invention relates to a wheel inward steering structure based on distributed hub drive. The wheel inward steering structure based on distributed hub drive comprises a first shock absorption systemand a steering system. The first shock absorption system is used for being connected with a wheel. The steering system comprises a steering support, a first mounting plate, a second mounting plate, afirst steering bearing, a second steering bearing, a steering main pin, a bogie and a steering engine. The steering engine drives the first mounting plate to rotate through the first steering bearing,and then the steering support and the first shock absorption system are driven to rotate. The first shock absorption system transmits the rotating moment to the wheel, and the wheel is driven to steer. Due to the fact that the first mounting plate and the second mounting plate are arranged on the side, away from the first shock absorption system, of the steering support, the maximum rotating angle of the steering support is 180 degrees, and then the maximum rotating angle of the wheel is 180 degrees, through the wheel inward steering structure based on distributed hub drive, the rotating angle range of the wheel is widened, and then flexibility of a vehicle is improved.

Description

technical field [0001] The present application relates to the technical field of automobiles, in particular to an in-wheel steering structure based on distributed wheel hub drive. Background technique [0002] The hub motor integrates the motor in the hub. Compared with the centralized drive, the distributed drive form with the hub motor as the power source has obvious advantages. The in-wheel motor can transmit torque to the driving wheel with only one wheel-side reduction mechanism at most, which greatly simplifies the transmission chain and effectively reduces the failure rate of the transmission system. The extremely short transmission chain will also effectively improve the mechanical efficiency of the powertrain. [0003] Existing steering systems generally use hydraulic power to change the direction of the wheels. The structure of the hydraulic power steering system is complicated, and the wheels are affected by the guiding mechanism, and the maximum turning angle i...
