Abstract

The invention discloses a dual-drive differential positive and reverse rotation transmission and multi-speed change device comprising a shell, a power mechanism, a first bevel gear, a second bevel gear, a locating shaft fixedly arranged in the shell, a first differential wheel, a second differential wheel and a planet wheel, wherein the first bevel gear and the second bevel gear are driven by thepower mechanism, the first differential wheel and the second differential wheel are rotationally connected to the locating shaft, the planet wheel is arranged between the first differential wheel andthe second differential wheel, the side, far away from the planet wheel, of the first differential wheel is meshed with the first bevel gear, the side, far away from the planet wheel, of the second differential wheel is meshed with the second bevel gear, the planet wheel comprises a power rotation ring on the outer side and three rolling bevel gears located inside the power rotation ring and rotationally connected with the power rotation ring, and the three rolling bevel gears are evenly distributed along the inner circumference face of the power rotation ring. The dual-drive differential positive and reverse rotation transmission and multi-speed change device has the effects of improving reversing speed of a positive and reverse rotation transmission device, solving the reversing pause problem existing during brake starting and improving the accelerating speed after reversing.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of drive devices, and in particular to a dual-drive differential forward and reverse transmission and a multi-stage transmission device. Background technique [0002] Existing forward and reverse drive: rely on the cycle of forward acceleration, deceleration, stop to reverse acceleration, deceleration, and stop of the motor. [0003] weakness is: [0004] 1. The commutation response of positive and negative rotation is slow. [0005] 2. The commutation stops due to the action of braking and starting. [0006] 3. Since each reversing must gradually accelerate from slow speed, the output torque of the motor is small, and frequent reversing due to the influence of inertial force, braking, and starting have a large impact on the transmission gear train, and the efficiency is low. Contents of the invention [0007] For this reason, the embodiment of the present invention provides a doub...
