Description

Technical field: [0001] The invention relates to the technical field of mechanical transmission, and more particularly to a deceleration device used on an electric truck. Background technique: [0002] Electric trucks refer to vehicles that are powered by on-board power supplies and drive wheels driven by motors, and meet the requirements of road traffic and safety regulations. Electric trucks do not have the exhaust gas produced by the internal combustion engine, and do not produce exhaust pollution, which is very beneficial to environmental protection and air cleanliness. Therefore, they are more and more favored by people. The reduction device on the electric truck plays the role of matching the rotational speed and transmitting the torque between the prime mover and the working machine or the actuator, and is an important factor to measure the performance of the electric truck. The deceleration device of the existing electric truck not only has a complex structure, but ...
