A method for hanging motors by axially precompressing combined elastic elements

Abstract

A method for suspending a motor by an axially precompressed combined elastic element includes suspending a motor of a vehicle on a bogie of that vehicle through an elastic composite elastic element; The elastic composite elastic element is an axial precompression combined elastic part, the vehicle motor is suspended on a bogie by the axial precompression combined elastic part, and the axial precompression combined elastic part is connected with the vehicle motor through a fastener to form the suspension of the vehicle motor. The axial precompression combined elastic part is composed of two elastic elements, the two elastic elements are clamped on the bogie by axial precompression from both sides of the bogie, and are combined together by axial precompression of fasteners to form an axial precompression combined elastic part. The axially precompressed composite elastic part is axially connected with the vehicle motor through the fastener, so that the vehicle motor is suspended on the bogie through the axially precompressed composite elastic part. The method for suspending a motor by an axially precompressed combined elastic element can effectively improve the condition of vehicle motor suspension, and meet the requirements of vehicle suspension in various harsh environments.

Description

technical field [0001] The invention relates to a method for installing vehicle components, in particular to a method for hanging a vehicle motor through axial precompression combined with elastic elements. The vehicle motor hanging method can effectively improve the comprehensive performance of the motor in all directions. So as to meet the motor suspension requirements of various complex working conditions; it belongs to the field of rail transit manufacturing technology. Background technique: [0002] Most of the traction motors of the vehicle are installed on the vehicle by means of suspension, and the motor suspension generally has two methods: shaft-holding type and bogie frame-supporting type. Wherein, the motor is suspended and fixed on the motor base for fixing or positioning the motor, and sometimes also as a connection part between the motor and the lifting equipment when the motor is lifted. For example, the suspension-type railway traction motor is fixed on the...

Problems solved by technology

[0009] The purpose of the present invention is to propose a new type of vehicle motor suspension method for the existing motor suspension method that is difficult to apply to various load conditions and is more severe, especially the problem that the existing elastic damping elements cannot meet the motor suspension requirements. This vehicle motor suspension method can greatly improve the comprehensive vibration reduction performance of the motor suspension, and effectively meet the elastic vibration reduction requirements of the motor suspension of the high-speed train system
