A 100% Low Floor Tram Power Bogie Frame

Abstract

The invention discloses a 100% low-floor tramcar power truck frame which comprises a bottom plate, and a cross beam and two side beams which are welded on the bottom plate, wherein a traction rod seat is welded on the outer side of the cross beam; a secondary spring seat, a motor base and a gearbox base are arranged on the side beams; a brake clamp seat is respectively welded with the gearbox base and the motor base into a whole; and a magnetic track brake guide seat, a primary spring seat, a transverse and vertical shock absorber seats, four groups of axle box rod seats and four transverse stop seats are arranged on the side beams. The 100% low-floor tramcar power truck frame disclosed by the invention has the advantages of compact structure, attractive appearance and reliable performance, and can meet the requirements of mounting interfaces of a power device, a primary suspension device, a secondary suspension device, a traction rod, vertical and transverse stoppers, vertical and transverse shock absorbers, a braking system and the like in the 100% low-floor tramcar. The framework has the structural characteristic that the framework is symmetrically arranged relative to the central point of the framework and can be steered by 180 degrees.

Description

technical field [0001] The invention relates to the field of trams, in particular to a 100% low-floor tram power bogie frame. Background technique [0002] With the continuous advancement of science and technology and the continuous improvement of people's quality of life, people have higher requirements for the convenience of travel. The reality is that there are more and more vehicles driving, urban roads are getting denser and wider, and the road surface is getting wider and wider. However, road congestion is still serious, and the travel time of urban residents is increasing. Noise and other pollution. [0003] In order to alleviate urban traffic congestion and pollution, many cities have accelerated the construction of subways as the main way to alleviate urban traffic congestion. However, the subway system has problems such as high investment costs and long construction periods. The low-floor modern tram is a low-to-medium-capacity transportation tool between the bus...

Problems solved by technology

Since the bogie is a component with relatively complicated stress, if there are too many welds, it is more likely to cause stress concentration, which will lead to the failure of the frame
