An adjustable power transmission system for rail vehicles

Abstract

The invention discloses an adjustable power transmission system for rail vehicles, comprising a bottom plate, a vertical pole is fixedly connected to the upper side of the bottom plate, and the two ends of the lifting pole respectively penetrate the side walls of the two vertical poles and are slidably connected to the chute Inside, the two ends of the lifting rod are connected with a sliding rod through a first spring, the upper side of the sliding rod is provided with a connecting block, the two sides of the connecting block are fixedly connected with electric contacts, and the two ends of the electric electric shock are electrically connected to cables respectively , the present invention makes the roller shaft contact the sliding line of the external contact net by sliding the sliding rod upwards. When the rail vehicle is running, when the roller shaft and the sliding wire are electrically connected, there is rolling friction between the roller shaft and the sliding wire. Therefore, on the basis of ensuring good performance, the wear of the roller shaft and the sliding wire is reduced, and the service life of the roller shaft and the sliding wire is increased. In addition, an adaptive arc groove is set to further reduce the wear and tear, and the split type of the roller shaft is adopted. Design reduces replacement cost and assembly difficulty.

Description

technical field [0001] The invention relates to the technical field of power transmission of rail vehicles, in particular to an adjustable power transmission system for rail vehicles. Background technique [0002] The electrical equipment that the rail vehicle obtains electrical energy from the catenary is installed on the roof of the rail vehicle to transmit the external power to the rail vehicle. The bow, that is, the friction contact between the pantograph and the sliding wire when the tram is running makes the vehicle electrify. This method makes the pantograph and the sliding wire wear extremely seriously during the operation of the electric vehicle, resulting in a short service life and a short replacement cycle. occurs, which in turn increases the cost of use, so we propose an adjustable power transmission system for rail vehicles. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an adjustable power transmission system for rail v...

Problems solved by technology

[0002] The electrical equipment used by rail vehicles to obtain electrical energy from the catenary is installed on the roof of the rail vehicle to transmit external power to the rail vehicle. Most of the existing power transmission devices on rail vehicles are sliding power receiving devices. The pantograph, that is, the frictional contact between the pantograph and the sliding wire when the electric car is running, makes the vehicle electrified. In this way, the pantograph and the sliding wire are extremely worn during the operation of the electric vehicle, resulting in a short service life and a short replacement cycle. occurs, which in turn increases the cost of use, so we propose an adjustable power transmission system for rail vehicles
