Abstract

The invention discloses a low-speed large-torque single reduction gear electric wheel, and belongs to the technical field of off-road vehicle chassis. The low-speed large-torque single reduction gearelectric wheel includes a hub device; a drive device arranged in the hub device; a supporting device connected to the drive device, wherein the hub device is movably arranged on the supporting device;a transmission device, wherein a first end of the transmission device is connected to an output end of the drive device, and the transmission device is arranged in the supporting device; a reducer arranged in the hub device, wherein the reducer is connected to a second end of the transmission device; a travel brake device arranged on the drive device, wherein the travel brake device is connectedto the hub device; a parking brake device connected to the drive device, wherein the parking brake device is arranged on an output end of the drive device. The low-speed large-torque single reductiongear electric wheel can achieve electric wheel driving, travel braking, parking braking, and heat dissipation in a designated time range.

Description

technical field [0001] The invention relates to the technical field of off-road vehicle chassis, in particular to a low-speed high-torque single-stage reducer electric wheel. Background technique [0002] The electric wheel refers to the drive wheel that integrates the motor and the wheel, which can realize the independent drive of the wheel of the electric vehicle. Since the wheels are directly driven by the wheel motor, the power control is changed from a hard connection to a soft connection, and the stepless speed change from zero to the maximum speed of each electric wheel and the differential speed requirements between each electric wheel are realized through the wire control technology, so that it can be omitted. The clutches, transmissions, transmission shafts and mechanical differentials required by traditional automobiles simplify the drive system and vehicle structure, increase the effective available space, reduce the weight of the vehicle, shorten the transmissio...
