Embodiment Construction

[0012] In order to make the purpose, technical solutions and advantages of the invention more clear, the technical solutions in the embodiments of the invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the invention. Obviously, the described embodiments are Invention type some embodiments, but not all embodiments.

[0013] Embodiments of the present invention provide a 100% low-floor tram non-powered bogie, such as figure 1 As shown, the non-power bogie includes a bogie frame 1, and anti-kink devices are arranged at both ends of the bogie frame 1. The anti-kink device specifically includes a hydraulic cylinder 5 provided at the end of the bogie frame 1, the piston of the hydraulic cylinder 5 is connected to the vehicle body, so that the piston of the hydraulic cylinder 5 moves under the control of the control system, thereby adjusting the bogie frame 1 and the vehicle body. relative position.

Abstract

The invention provides a 100% low floor tramcar non-power bogie and a tramcar. The 100% low floor tramcar non-power bogie comprises a bogie framework; one anti-twisting device for regulating relative positions of the bogie framework and a vehicle body is arranged at the front end and the rear end of the bogie framework respectively. According to the 100% low floor tramcar non-power bogie and the tramcar which are provided by the invention, through the arrangement of the anti-twisting devices at the two ends of the bogie framework, the bogie has good guidance quality in the running process of the tramcar, the peak of force applied by each wheel to a rail can be greatly reduced, wear of a rim of each wheel on a curve track, which is caused by the case that the wheel is close to the steel rail, is reduced, the service life of the tramcar is prolonged, and meanwhile the tramcar has an automatic resetting and centring function, so that the tramcar has good comfort.

Description

technical field [0001] The invention relates to the field of rail trains, in particular to a 100% low-floor tram non-powered bogie and a tram. Background technique [0002] In 1990, the world's first 100% low-floor tram was officially unveiled in Bremen, Germany. Since then, urban trams have entered the era of 100% low-floor. The floor height of 100% low-floor trams is usually about 350mm, which is convenient for passengers, especially children, disabled people in wheelchairs, etc. to get on and off. At the same time, it is convenient for passengers to move in the car, reducing the time for getting on and off the car. According to foreign statistics, compared with ordinary light rail vehicles, the time for passengers getting on and off the low-floor vehicles is reduced by 30%. By adjusting the marshalling method of trains, the traffic volume demands of different cities and lines can be met. [0003] As the running device of the tram, the bogie is a key component for its o...
