The invention discloses a hub reducer provided with a duplicate planet gear and belongs to the field of speed reducing devices of an engineering machinery technology. The hub reducer disclosed by theinvention is integrated with a hub motor, the hub motor is used for directly driving wheels to move forwards after two-stage speed reduction, therefore the structure of a transmission system is simplified, and the efficiency of the transmission system is improved. According to the hub reducer disclosed by the invention, a traditional inner gear ring is canceled so that the structure of a planet gear mechanism is more compact, the size of the hub reducer is greatly reduced, the problem that the hub space is limited is solved, and the spatial arrangement property of the hub reducer is improved.By adopting a two-stage planet gear reduction mechanism, the hub reducer can achieve a larger transmission ratio range so as to provide larger driving force for a vehicle, thereby improving the powerperformance and the gradeability of the vehicle.
Description
technical field [0001] The invention belongs to the field of deceleration devices in construction machinery technology. Background technique [0002] In the 1950s, American scientists invented the wheel reducer. Its function is to transmit the speed and torque output by the motor to the wheels after deceleration and torque increase, so that the wheels can generate enough driving force to drive the vehicle under the reaction of the ground adhesion. go ahead. [0003] At present, most of the wheel-side reducers for vehicles on the market are one-stage reduction mechanisms, which cannot achieve a large transmission ratio, which leads to insufficient driving force transmitted to the wheels, and greatly affects the vehicle's power performance and climbing ability. However, the wheel-side reducer using a multi-stage planetary gear mechanism has problems such as large volume, complex structure, and high noise, which is not conducive to the space layout of the reducer and the drivi...
