Abstract

The invention provides a power bogie for a meter gauge. The power bogie comprises two support beams, a single arbor wheel set, a gearbox, two sets of barometric disc brakes, four air springs, two height control valves, two traction rods and two locating rods, wherein two wheels and a brake disk are directly pressed on an axle, and the wheels and the brake disk are fixedly connected; the support beams are supported on the axle by bearings, and the bearings and the brake disk are horizontally located by shaft sleeves; the gearbox is arranged on the axle; the barometric disc brakes are connectedon the support beams via installation seats; the four air springs are arranged at the four corners of the support beams; the heights of every two air springs are controlled by the same height controlvalve; each support beam is provided with one traction rod and one locating rod; and the middle of the support beam is provided with a transverse backstop. The power bogie provided by the invention has compact and reasonable overall structure layout and good curve passage capacity and is more suitable for urban light rail traffic meter gauge lines and narrow car bodies.

Description

technical field

[0001] The invention relates to the technical field of wheel-rail train bogies, in particular to a meter-gauge power bogie. Background technique

[0002] As the key component of wheel-rail train, the performance of bogie directly affects the running quality and safety of the vehicle. In the composition of the overall weight of the bogie, the wheelset occupies a considerable proportion. Studies have shown that the use of articulated connections and single-axle bogies can reduce the weight of the vehicle group by 7-14%, and save up to 9% of traction power.

[0003] The single-axle bogie has not been developed, manufactured and used in China, and it is limited to the theoretical research of the relevant academy of sciences, and there is no mature application experience for reference. In foreign countries, the systematic research on the theory of single-axle bogies has only started in recent years, and in the same period, various prototype vehicles and products...
