Abstract

The utility model relates to a full electric vehicle front-and-back supporting structure of an input shaft and a middle shaft of a driver. The full electric vehicle front-and-back supporting structure of the input shaft and the middle shaft of the driver comprises the middle shaft, the input shaft and self-sealing bearings, wherein the middle shaft and the input shaft are both supported by the self-sealing bearings in front and at the back. The full electric vehicle front-and-back supporting structure of the input shaft and the middle shaft of the driver has the advantages of being convenient to install, enabling the input shaft and the middle shaft to acquire a radial load with high rotation speed and large bearing, and effectively improving the noise vibration and harshness (NVH) of an electronic control transmission (ECT) to be matched with the mute feature of a full electric vehicle.

Description

Pure electric vehicle driver input shaft, jack shaft front and back supporting structure
Technical field
The utility model relates to a kind of pure electric vehicle driver input shaft, jack shaft front and back supporting structure.
Background technique
As everyone knows, along with world energy sources crisis and environmental issue become increasingly conspicuous, automotive industry is faced with stern challenge: on the one hand, the petroleum resources shortage, automobile is the oil consumption rich and influential family, the automobile pollution that climbs up and up has aggravated this contradiction; A large amount of uses of automobile have aggravated environmental pollution on the other hand; Along with continuing to increase under the resource and environment dual-pressure; The development new-energy automobile is to become the direction of automobile industry development; It is topmost wherein developing electric vehicle, but pure electric automobile driver noise is big at present, rotating speed is low, the life-span is short.
Summary of the invention
In order to solve the problem of electric vehicle driver, the utility model provides a kind of pure electric vehicle driver input shaft, jack shaft front and back supporting structure.The technological scheme that the utility model adopts is: it mainly comprises jack shaft, input shaft and selfsealings ball bearing composition, supports by the selfsealings ball bearing before and after jack shaft and the input shaft.
The utlity model has easy for installationly, make input shaft, jack shaft obtain high rotating speed, bear big radial load, improve the whole NVH of ECT effectively, to cooperate the characteristics such as quiet characteristic of pure electric vehicle.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
