The invention relates to a front and back support structure of an input shaft and an intermediate shaft in an all-electric automobile transmission. According to the technical scheme, the structure mainly comprises an intermediate shaft, an input shaft and self-sealing ball bearings; both the front and back of each of the intermediate shaft and the input shaft are supported by the self-sealing ball bearings. The front and back support structure of the input shaft and the intermediate shaft in the all-electric automobile transmission has the advantages that the structure is convenient to mount, the input shaft and the intermediate shaft are provided with high speed and can bear large radial load, overall NVH (noise, vibration and harshness) of the ECT are improved effectively, the muteness feature of the all-electric automobile is fitted.
Description
technical field [0001] The invention relates to a front and rear support structure of an input shaft and an intermediate shaft of a pure electric vehicle transmission. Background technique [0002] As we all know, with the world's energy crisis and environmental protection issues becoming more and more prominent, the automobile industry is facing severe challenges: on the one hand, oil resources are in short supply, and automobiles consume a lot of fuel. Extensive use of environmental pollution has aggravated the environmental pollution. With the continuous increase of the dual pressure of resources and environment, the development of new energy vehicles has become the direction of the development of the automobile industry. Among them, the development of electric vehicles is the most important, but the current transmission noise of pure electric vehicles is relatively low. Large, low speed, short life. Contents of the invention [0003] In order to solve the problem of t...
