Problems solved by technology

However, due to the use of a hanger, the traction motor needs to be connected to the hanger, and the hanger is connected to the frame beam through a leaf spring, which makes the overall structure too complicated, difficult to manufacture and maintain, and also increases the manufacturing cost

Abstract

The invention relates to the technical field of traction motor suspension decoupling, and discloses a high-speed bogie traction motor transverse decoupling elastic suspension mechanism based on spring plates. The mechanism comprises a framework cross beam and a traction motor, four first mounting bosses are arranged on the framework cross beam, four second mounting bosses are arranged on the traction motor, four first mounting seats and second mounting seats are arranged in a matrix mode, a decoupling assembly is arranged on the first mounting bosses and the second mounting bosses, and comprises two sets of parallel decoupling devices, each set of decoupling device comprises two spring plates, elastic pins are arranged at the four corners of the two spring plates of each set of decoupling device respectively, and the two sets of decoupling devices are arranged on the first mounting bosses and the second mounting bosses of the framework cross beam and the traction motor through the elastic pins. Transverse decoupling of the traction motor and the framework is achieved, a traction motor body and the framework are elastically and fixedly connected together in the longitudinal direction and vertical direction, and the traction motor and the framework are separated in the transverse direction.

Description

technical field [0001] The invention relates to the technical field of traction motor suspension decoupling, in particular to a spring-plate-based high-speed bogie traction motor lateral decoupling elastic suspension mechanism. Background technique [0002] The traction motor is traditionally suspended on the frame, the traction motor and the frame are integrated, and the mass between the springs is relatively large, which affects the critical speed and stability of the serpentine shape. If the traction motor adopts the lateral decoupling elastic suspension mode, it will reduce the mass of the frame assembly and the inertia of the shaking head, which will help to increase the serpentine critical speed of the bogie, improve the stability, and reduce the wheel-rail force. [0003] The CRH380B / BL bogie is a classic elastic frame suspension bogie of the traction motor used in the CRH3 EMU in China, and its prototype is the Siemens SF500 bogie. The CRH380B / BL bogie driving devic...
