Problems solved by technology

At the moment when the gap is eliminated and the power is output, there will be setbacks, impacts, and abnormal noises, which will seriously affect the driving experience and the normal wear of the gearbox gears and various connecting parts.
The existing ordinary gearbox structure cannot shield this defect when it is applied to electric motor vehicles. Due to the different structures of new energy vehicles of various structures, this defect exists more or less

Embodiment Construction

[0014] See figure 1 Shown is a schematic structural diagram of this embodiment. The torsion damping gear of this embodiment includes a transmission gear 1, a transmission shaft 2, a bearing 3 (or bushing), a lock nut 4, a sliding block 5, a spring 6, and a damping ring 7 and other components. Please combine the specific structure figure 1 And the following explanation:

[0015] The transmission gear 1 is provided with an axial inner hole 11, and an inner spline is provided on the wall of the inner hole 11. The internal splines are matched with the slider 4. The right end of the transmission shaft 2 is fixed in the inner hole 11 of the transmission gear 1 through a first bearing 31 and a second bearing shaft 32. The diameter of the right end of the transmission shaft 2 is higher than the diameter of the inner hole 11, forming a stepped shape. The material of the first bearing 31 and the second bearing shaft 32 is a pad bearing anti-friction material, whose function is to determ...

Abstract

The invention discloses a torsion damping gear comprising: a transmission gear, the transmission gear is provided with an axial inner hole, and internal splines are arranged on the hole wall of the inner hole; a transmission shaft, the right end of the transmission shaft passes through The first bearing and the second bearing are axially fixed in the inner hole of the transmission gear; the lock nut is threaded through the left end of the transmission shaft and locked on the left end of the transmission gear; the slider , which is sleeved on the transmission shaft in the inner hole, and the outer wall of the slider is provided with an outer spline, and the outer spline cooperates with the inner spline so that the slider can move along the The transmission shaft moves axially, and the slider slides along the transmission shaft under force when decelerating or accelerating; the spring is sleeved on the transmission shaft and is located between the transmission shaft and the slider , when the slider is in contact with the right end of the transmission shaft, the impact force is absorbed. The application solves the problems of setbacks, shocks and abnormal noises in the gearbox when the transmission is decelerated and then accelerated again.

Description

Technical field [0001] The invention relates to the field of electric gearboxes, and more specifically, to a torque damping gear. Background technique [0002] The power output of the electric motor of a new energy vehicle or hybrid vehicle is transmitted to the wheels through many levels of gears, and there is a certain gap between each gear. Many gears will accumulate a large gap from the input including spline connection to the wheel. Under normal driving conditions, when the car is decelerated and then accelerated, the gap should be eliminated before the normal output power when the reverse force is applied between the gears and then the forward force is applied. At the moment when the gap is eliminated and the power output, there will be frustration, impact, and abnormal noise, which will seriously affect the driving experience and the normal wear of the transmission gear and various connecting parts. The application of the existing ordinary gearbox structure to electric m...
