Problems solved by technology

[0004] The current low-floor bogie frame basically protrudes from the middle of the longitudinal beam to fix the motor. However, the installation of the motor leads to a very limited installation space for the magnetic track brake, and the impact force of the motor when the tram is running It is easy to loosen and there is a safety hazard

Embodiment Construction

[0028] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

[0029] A low-floor bogie frame such as figure 1 As shown, the bogie frame adopts an "H" structure, including side beams 2, wing beams 4, cross beams 6 and end beams 1. The side beams 2 protrude outward and connect with the wing beams 4 to form a cantilever structure. The beam adopts a square frame structure to connect the middle parts of the two side beams, and the end beam adopts a U-shaped structure to connect with the ends of the side beams. Such as ...

Abstract

The invention discloses a bogie frame, a bogie and a rail vehicle. The bogie frame comprises a frame body mainly composed of two side beams, a crossbeam and two end beams, wherein the frame body is shaped like a Chinese character 'ri'. The bogie frame further comprises two wing beams fixed to the outer sides of the corresponding side beams. The two wing beams arranged in the length direction of the crossbeam form cantilever type structures. Motor installation seats are arranged on each wing beam in the longitudinal direction. Preferably, the two ends of each wing beam in the longitudinal direction are both provided with the motor installation seats. The bogie frame has the remarkable beneficial effects of being smooth in appearance, reliable in performance, stable in structure and the like.

Description

technical field [0001] The invention relates to a bogie frame, a bogie and a rail vehicle, belonging to the field of rail vehicles. Background technique [0002] Low-floor trams have the advantages of low line construction cost, environmental protection and energy saving, safety and comfort, and flexible marshalling. Therefore, more and more cities choose them as transportation systems to solve the increasingly congested urban traffic problems. [0003] The low-floor bogie is an important part of the low-floor tram. Among them, the low-floor bogie frame is the main part, which plays the role of connecting various functional components, bearing and transmitting loads, etc., and requires compact structure, reliable operation, and high stability. , Good adaptability to uneven lines, etc., can effectively reduce the impact force of the tram when it is running, improve the running quality, and prolong the service life of the components. The bogie frame of the low-floor tram is pr...
