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 suspending and decoupling of traction motors and discloses a transverse decoupling elastic frame suspending mechanism for a traction motor of a high-speed bogie. A frame beam of the transverse decoupling elastic frame suspending mechanism is parallel to the axis of the traction motor and provided with four first installing bases. Four second installing bases are arranged on the traction motor. Decoupling assemblies are installed on the first installing bases and the second installing bases. Each decoupling assembly comprises two decoupling bodies arranged in parallel. Spherical hinge joints with central spindles are arranged in round holes in the four corner ends of each decoupling body. The decoupling assemblies are located between the frame beam and the traction motor. The central spindles of the four spherical hinge joints of one side are fixedly connected with the four first installing bases and the four second installing bases of the same side. An elastic pre-tightening anti-diamond device is arranged between every two decoupling bodies. As transverse decoupling of the traction motor and a frame is achieved, the traction motor can be elastically and firmly combined with the frame in the longitudinal direction and the vertical direction, and the traction motor is separated from the frame in the transverse direction.

Description

technical field [0001] The invention relates to the technical field of traction motor suspension decoupling, in particular to a laterally decoupling elastic suspension mechanism of a traction motor of a high-speed bogie. 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 device is es...
