High-acceleration electric rail car

Abstract

The invention discloses a high-acceleration electric rail car which is in a layout mode characterized in four-wheel travelling and four-wheel guiding. A car body structure is bilateral and sagittal symmetry; guide wheel pairs are connected by virtue of a guide bridge, are installed on a guide frame, are positioned on the head side and tail side of the rail car body and act on I-shaped steel rails on two sides; front and rear driving wheel pairs are installed on a drive axle and act on hard ground between the steel rails to bear the vertical load of the car body and transfer traction force and braking force to a pavement; front and rear guide wheel pairs and the car body are connected by virtue of the guide frame; a direct-current motor, an energy system and a vehicle-mounted control system are all arranged on the car body; the energy system is a vehicle-mounted super capacitor; and the vehicle-mounted control system is used for controlling the direct-current motor and the energy system to work. According to the high-acceleration electric rail car, the problem that the rail car does not have higher acceleration capability in the traditional scheme generally can be overcome, and the high-acceleration electric rail car has the high-acceleration capability of the electric car as well as the guidance action and offset inhibition capability of the rail car.

Description

technical field [0001] The invention relates to a rail car technology, in particular to an electric rail car with high acceleration capability designed by combining electric drive technology with a rail car system. Background technique [0002] With the development of high-speed rail technology and urban subways, rail transit has increasingly affected people's production and life. According to different design purposes and main uses, railcars can be divided into special railcar bodies in industrial production and general trains. The former includes electric flat cars, railway maintenance cars, etc. Most of them drive iron wheels on I-shaped tracks based on mechanical, hydraulic, and electric transmission. The latter includes intercity trains, underground railways, high-speed rail, etc. Due to the pure rigid body contact between the rail wheel and the rail, the lateral deviation of the car body during driving will be greatly suppressed, so the car body is stable and the lat...
