New energy vehicle motor end cover and bearing chamber structure

Abstract

The invention discloses a new energy vehicle motor end cover and bearing chamber structure. The structure comprises a motor end cover, a bearing chamber, a bearing, a heat exchange mechanism and a spiral cooling mechanism, wherein the bearing chamber is arranged in the middle part of the motor end cover, the bearing is mounted at an inner cavity of the bearing chamber, the heat exchange mechanismis arranged on an inner wall of the motor end cover, the heat exchange mechanism is mounted at a central position of the inner cavity of the motor end cover; the heat exchange mechanism comprises a heat absorption piece, a gas filling pipe, a pressure balancing plug, a pushing needle, an air inlet pipe and a sealing sheet; and the spiral cooling mechanism comprises a bearing spring, a cooling spiral tube and a heat exchange sleeve. The new energy vehicle motor end cover and bearing chamber structure can accurately and quickly perform heat exchange and cooling for a motor in a working process without generating a dirt retention problem, and can provide certain buffer time for the motor in operation when a shell is disjointed, and thus, probability of accidents caused by jamming is reduced.

Description

technical field [0001] The invention relates to the technical field of fan manufacturing and processing, in particular to a new energy vehicle motor end cover and a bearing chamber structure. Background technique [0002] With the continuous development of industrial production, all walks of life have made considerable progress and progress in their own fields. Among them, the progress and replacement of the automobile industry are relatively rapid, and the changes are also great. The most direct change is It is the rise and development of new energy vehicles, which is of great significance to the environment, energy consumption and the conservation of non-renewable resources. [0003] In the process of automobile production and manufacturing, a large number of various parts and electrical components are used, among which is the equipment of motor. As for the motor, this existing and well-known equipment is also relatively common in production and life. It is mainly used as...
