Abstract: An in-corner modular electric wheel system integrating adjustable king pin and king pin type steering unit includes a wheel assembly, a steering system, a king pin inclination adjusting system and a suspension system. The wheel assembly is configured to support a load of a vehicle, transmit a driving torque and determine a toe angle and a camber angle. The steering system is a king pin type steering system, and is configured for an omni-directional independent wheel steering. The king pin inclination adjusting system is sleeved on the king pin, and is configured to adjust an inclination of the king pin without changing the camber angle. The suspension system has an unequal-length double-wishbone suspension structure, and is provided with a coil spring and a shock absorber to mitigate road impacts and improve ride comfort.

Abstract: A self-energy-storage wheel corner module integrating omni-directional redundant steering and energy regenerative suspension, including a wheel assembly, a suspension system having an unequal-length double wishbone suspension structure, a first steering system, a drive system, a braking system, a second steering system, an energy storage system and an actuator assembly. The first steering system is a primary steering system, and has low steering delay and excellent maneuverability at high speeds. The second steering system is a redundancy of the first steering system, and contributes to the omni-directional steering of the wheel assembly, which enhances the vehicle maneuverability. A motor of the second steering system also functions as another actuation motor of the actuator assembly in an idle state to enable the suppression and energy regeneration of the suspension vibration.

Abstract: A four-mode dual-motor coupled electric drive axle, including a primary drive motor, an auxiliary drive motor, a reducer, a torque vectoring (TV) coupler, a power coupling differential, a housing, and a power output mechanism. The TV coupler is switchable among disconnected mode, TV mode, and reducer mode by controlling a first clutch and a second clutch. The power coupling differential is switchable between torque coupling mode and speed coupling mode by controlling a third clutch. The electric drive axle is switchable among single-motor drive mode, TV drive mode, dual-motor torque coupling drive mode, and dual-motor speed coupling drive mode by controlling the TV coupler and the power coupling differential.
