Abstract

The invention discloses a rail operation vehicle transmission system. A rail operation vehicle comprises a power vehicle and an operation vehicle; the rail operation vehicle transmission system comprises a vehicle power supply system, a high speed running system and a low speed running power source, a low constant speed running system and an operation system, wherein the vehicle power supply system, the high speed running system and the low speed running power source are placed on the power vehicle; the low constant speed running system is placed on the operation vehicle; and the operation system is partially or totally placed on the operation vehicle. The vehicle power supply system provides a power supply for the operation system and can selectively provide power supply for the high speed running system or the low speed running power source; and the high speed running system adopts an electric drive traction system. The low speed running power source provides a hydraulic power sourcefor the low constant speed running system; and the low constant speed running system adopts an electric drive hydrostatic transmission traction system. According to the rail operation vehicle transmission system, a technical problem of power transmission of a double-power-source rail operation vehicle in high speed running and low running modes can be solved to satisfy requirements on a running speed and control accuracy under different working conditions.

Description

technical field [0001] The invention relates to the technical field of railway engineering machinery, in particular to a transmission system structure of a dual power source driven rail vehicle. Background technique [0002] As a widely used rail operating vehicle, the rail milling and grinding vehicle is a rail engineering maintenance vehicle used to repair rail surface defects. The rail milling and grinding vehicle processes the surface of the rail through the milling unit and the grinding unit installed on the vehicle chassis, so that the parameters such as the roughness, wave grinding and profile of the rail surface reach the required value. The cutter on the milling unit mills the surface of the rail to eliminate damage and corrugation on the surface of the rail to control the cross-sectional profile. The grinding wheel on the grinding unit grinds the rail surface after milling chips to make the rail surface smoother and reach the required roughness value. The rail mi...
