Abstract

The invention provides a two-axle locomotive transmission system. The two-axle locomotive transmission system includes a frequency conversion module, two traction motors, two cardan axles and two axlegear boxes, wherein the input end of the frequency conversion module is connected with a power storage battery or an overhead line, the output end of the frequency conversion module is connected withthe two traction motors correspondingly, and the output ends of the two traction motors are back-to-back arranged and transmits power to the axle gear boxes at the two ends of the axle correspondingly through the cardan axles. The two-axle locomotive transmission system has the beneficial effects that the two traction motors are used for driving the two axle gear boxes correspondingly, even if one traction motor fails, the other traction motor can still perform normal traction, the concept of redundant design is reflected; and the novel transmission system can adopt various different power sources of the power storage battery, a power grid, and the like, so that the operation demand under different working conditions can be ensured, realizing of being environment-friendly is further facilitated.

Description

technical field [0001] The invention relates to a two-axle locomotive transmission system, which belongs to the technical field of rail transportation. Background technique [0002] At present, the two-axle rail locomotive is mainly based on hydraulic transmission. The internal combustion engine and hydraulic transmission box are installed on the frame. The internal combustion engine provides power and drives the hydraulic transmission box to output torque, and drives the wheelset through the cardan shaft and the axle gearbox. Such as figure 1 shown. [0003] The power source of the hydraulic drive system is often an internal combustion engine, and the hydraulic transmission box transmits the power of the internal combustion engine to the axle gearbox and drives the wheelset. Due to the low transmission efficiency of the hydraulic transmission box, it is difficult for the power source of the internal combustion engine to adapt to the current environmental protection requir...
