RAIL MILLING VEHICLE TRANSMISSION SYSTEM

摘要

A rail milling vehicle transmission system comprises a main engine (1), a transfer case (2), a traction generator (3), a traction motor (4), a gearbox (5), and a wheel pair (6) all sequentially connected, and a traction controller (7) connected to the traction motor (4). The present invention employs an electric drive technique for driving the traction motor (4) and controls the milling vehicle to travel at a high speed or a slow constant speed via the traction controller (7) electrically connected to the traction motor (4), and enables the milling vehicle to travel at a high speed and a slow constant speed and satisfies the demands of a traction condition and a working condition via a set of drive system. The drive system has a simple and compact structure and addresses a technical problem of a complex structure of the drive system in the prior art.
