Abstract

The invention discloses a rail engineering vehicle transmission method, which comprises the following steps of: arranging a whole vehicle power supply system and a high-speed running system on a powervehicle, and arranging a low-speed running system on an operating vehicle; the operation vehicle is independently arranged, or an operation system is arranged on the power vehicle and the operation vehicle; b) the whole vehicle power supply system supplies power to the operation system, and selectively supplies power to the high-speed running system or the low-speed running system; c) high-speedwalking is realized through a high-speed walking system, and the high-speed walking system adopts electric transmission traction to realize high-speed walking and low control precision; and (D) low-speed walking is achieved through the low-speed walking system, all-electric transmission traction is adopted in the low-speed walking system, speed reduction is conducted through a speed reduction mechanism, and therefore low-constant-speed walking and high control precision are achieved. The technical problem of power transmission of the double-power-source rail operation vehicle in the high-speedwalking mode and the low-speed walking mode can be solved, and the requirements for the walking speed and the control precision under different working conditions are met.

Description

technical field [0001] The invention relates to the technical field of railway engineering machinery, in particular to a transmission control method for driving rail engineering vehicles with dual power sources (catenary power supply + traction battery power supply). Background technique [0002] As a widely used rail working 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 rai...
