Abstract

The invention discloses a track operation vehicle power transmission method. A track operation vehicle comprises a power vehicle and an operation vehicle. The method comprises the following steps: A)setting an overall power supply system, a high-speed walking system and a low-speed walking power source on the power vehicle, setting a low-constant speed walking system on the operation vehicle, andsetting an operation system on the operation vehicle independently or on the power vehicle and the operation vehicle; B) supplying power to the operation system from the overall power supply system,selectively supplying power to the high-speed walking system and the low-speed walking power source, and providing an electric transmission traction system for the high-speed walking system; C) providing a hydraulic power source for the low-constant speed walking system from the low-speed walking power source, and providing an electric transmission static hydraulic transmission traction system forthe low-constant speed walking system. By adopting the method, the technical problem of power transmission of a double-power source tract operation vehicle in high-speed walking and low-speed walkingmodes can be solved, and requirements on walking speeds and control precision under different working conditions can be met.

Description

technical field [0001] The invention relates to the technical field of railway engineering machinery, in particular to a power transmission method for a rail work vehicle driven by dual power sources. 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 r...
