Problems solved by technology

[0003] However, for the design of the combination of motor full suspension and double-sided six-linkages, its structure has disadvantages such as relatively complex structure, heavy weight, large space occupation, and poor assemblability. The vibration effect is poor, the displacement ability is poor, there are wear and tear, and maintenance is required.
For the design scheme of motor full suspension, it has disadvantages such as poor displacement ability of direct drive coupling and poor driving vibration damping effect, which makes the life cycle of related components shorter and leads to higher cost of use

Abstract

The invention provides a wheel set driving system and a rail vehicle. The wheel set driving system comprises a motor, a suspension assembly and a flexible coupling assembly, wherein the motor comprises a case; the suspension assembly comprises a hanging rod and a suspension arm; one end of the hanging rod is connected to one side of the case through a first rubber joint, and the other end is connected to a framework through a second rubber joint; one end of the suspension arm is connected to the other side of the case, and the other end is connected to the framework through a third rubber joint; the flexible coupling assembly comprises a rotating shaft, a force transmission disc and a transmission disc; the rotating shaft penetrates through the case; one side of the force transmission discis connected to one end of the rotating shaft through a first flexible plate diaphragm, and the other side is connected to an output shaft of the motor; and one side of the transmission disc is connected to the other end of the rotating shaft, and the other side is connected to a driving wheel through a second flexible plate diaphragm.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a wheel set drive system and a rail vehicle. Background technique [0002] In existing rail vehicles, especially direct-drive locomotives, poor coupling displacement capability and poor driving vibration damping effect are technical problems to be solved urgently in this field. The coupling structure and suspension damping structure of existing rail vehicles usually adopt the design scheme of motor full suspension, combination of motor full suspension and double-sided six-link rods, motor full suspension and flexible plate diaphragm. [0003] However, for the design of the combination of motor full suspension and double-sided six-linkages, its structure has disadvantages such as relatively complex structure, heavy weight, large space occupation, and poor assemblability. The vibration effect is poor, the displacement ability is poor, there are wear and tear, and maintenance...
