Abstract

The invention provides a hybrid power drive system based on electric drive. The hybrid power drive system includes a storage battery and an internal combustion system which includes a diesel engine and an electric generator, a traction converting unit, a traction motor, and braking resistance. The traction converting unit is electrically connected with the storage battery and the electric generator, and the traction converting unit converts direct current and alternating current electric energy generated by the storage battery and the electric generator into the alternating current electric energy; the traction motor is connected with the traction converting unit through a wiring harness; and the braking resistance is used for consuming electric energy generated by the traction motor. Theinvention further provides a rail engineering vehicle. According to the hybrid power drive system based on the electric drive, compared with related technologies, the reliability is high, energy conservation and environment protection are achieved, and braking force is high.

Description

technical field [0001] The invention relates to the field of electric transmission systems, in particular to a hybrid power transmission system based on electric transmission and a rail engineering vehicle used in track engineering. Background technique [0002] In recent years, with the rapid development of my country's railways, there are more and more railway tunnels and long ramp lines, and the power transmission technology adopted by the track engineering vehicles on the railway is based on a single engine as the power, that is, the power of the track engineering vehicles of related technologies The transmission form is internal combustion mechanical transmission or internal combustion hydraulic transmission. [0003] At present, the mechanical transmission system of rail engineering vehicles adopts a single transmission form, and the complex structure of the mechanical transmission leads to many intentional problems; in the hydraulic transmission mode, most of them use ...
