Self-powered railway official rail car

Abstract

The invention provides a railway official business rail car with power. A car group is formed by connecting a first official business rail car with the power and a second official business rail car with the power by a car coupler and a folding shed windshield; according to the car group, unit operation and double coupled running can be realized; the first official business rail car and the second official business rail adopt fluid drive to realize stepless speed change. The whole car group disclosed by the invention adopts a dynamic sinking type arrangement mode, single car is a fluid drive four-axis rail car, the highest self-operation speed is 120km / h, and the railway official business rail car with the power has advantages of stability in driving and good dynamics performance, and the safe operation of a high-speed railway can be completely satisfied.

Description

technical field [0001] The invention belongs to the technical field of railway engineering vehicles, and in particular relates to a railway official rail vehicle with its own power. Background technique [0002] In recent years, my country's railways have achieved leapfrog development. In order to ensure the safe operation of high-speed railways, it is necessary to strengthen the inspection of track lines. The existing railway official vehicles mostly use motor vehicles to pull unpowered official vehicles to patrol the track lines, or It is a single official car with its own power to patrol the track line. When encountering a large slope, the engine of a single official car needs to be fully loaded or close to full load. my country's terrain is uneven, and railways are often built in rugged mountainous areas. In places, there are many long or gentle slopes, and if this continues, the life of the engine will be greatly reduced; moreover, general official vehicles are mechanical...

Problems solved by technology

[0002] In recent years, my country's railways have achieved leapfrog development. In order to ensure the safe operation of high-speed railways, it is necessary to strengthen the inspection of track lines. The existing railway official vehicles mostly use motor vehicles to pull unpowered official vehicles to patrol the track lines, or It is a single official car with its own power to patrol the track line. When encountering a large slope, the engine of a single official car needs to be fully loaded or nearly full. The terrain in our country is uneven, and railways are often built in rugged mountainous areas. There are many long or gentle slopes in places, and if this continues, the life of the engine will be greatly reduced; moreover, general official vehicles adopt mechanical control methods, and the driver needs to frequently step on the clutch when the train is on a straight track or a line with a slope. , Changing gears to adapt to the operation of different lines will virtually increase the difficulty of driving for the driver, and long-distance driving will make people very tired, so it is necessary to propose improvements
