Reducer of new-energy vehicle

Abstract

The invention discloses a reducer of a new-energy vehicle. The reducer comprises a casing; three grooves are formed in the outer wall of the top of the casing and have semi-circular cross sections; second bearing blocks are clamped at the inner walls of the bottoms of the three grooves; a first rotating rod, a second rotating rod and a third rotating rod are rotationally connected to the inner walls of the sides of the second bearing blocks separately; a first helical gear and a third planet gear are welded on the circumference of the first rotating rod separately; the first helical gear meshes with a second helical gear; and an output shaft is welded in the middle of the outer wall of one side of the second helical gear. According to the reducer, a first sun gear and a second planet gearcan rotate together to dive a first planet gear and a second sun gear, and the very good speed reduction effect can be realized through a series of transmission meshing, so that the application rangeis wide; and under the interaction of elastic blocks and mass blocks, the pitch vibration of the main reducer can be reduced, and the vibration reduction requirement of the main reducer of the vehiclecan be met.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a reducer for new energy vehicles. Background technique [0002] The reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching speed and transmitting torque between prime mover and working machine or actuator, and is widely used in modern machinery. [0003] In traditional new energy vehicles, pure rubber mounts are used to meet the needs of automobile shock absorption and vibration isolation. Although their design and production costs are relatively low, because rubber is easy to age and its elasticity is weakened, its vibration reduction after a period of use The effect is significantly reduced, and the damping effect of pure rubber mounts at low frequency vibrations...

[0003] In traditional new energy vehicles, pure rubber mounts are used to meet the needs of automobile shock absorption and vibration isolation. Although their design and production costs are relatively low, because rubber is easy to age and its elasticity is weakened, its vibration reduction after a period of use The effect is significantly reduced, and the mitigation effect of pure rubber mounts at low frequency vibrations is poor
