Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0024] Such as Figure 1 to Figure 5 As shown, a rail vehicle trailer bogie frame is used for a trailer bogie in a rail vehicle, and is composed of two side beams 1, two end beams 2, a main beam 3 and two auxiliary beams 4 connected into a whole by welding frame structure. The frame 7 adopts an integral welded structure, which can improve the strength and rigidity of the overall structure of the frame, and can improve the connection stability of the equipment, and can effectively simplify the connection structure between the beams and meet the lightweight requirements.

[0025] Such as figure 1 and image 3 As shown, the two side beams 1 are box-shaped structures, which are spliced ​​by welding the top plate, the bottom plate and the two side plates, and the top plate, the bottom plate and the two side plates are all made of steel plates. Th...

Abstract

The invention discloses a railway-vehicle trailer bogie frame. The railway-vehicle trailer bogie frame is composed of two side beams, two end beams, a main crossbeam and two auxiliary crossbeams, wherein the two end beams are connected with the two ends of each side beam respectively, the two ends of the main crossbeam are fixedly connected with the middles of the two side beams, the two auxiliary crossbeams are arranged on two sides of the main crossbeam, the two ends of each auxiliary crossbeam are fixedly connected with the two side beams, and the side beams and the main crossbeam are of a box-shaped structure. The overall structure of the railway-vehicle trailer bogie frame is optimized, occurrence of high stress areas is reduced or avoided, the strength and rigidity of the overall structure of the railway-vehicle trailer bogie frame are improved substantially, overall anti-fatigue performance of the railway-vehicle trailer bogie frame is improved greatly, the overall stress level of the railway-vehicle trailer bogie frame is controlled within the range allowed by the strength, and the requirement for safe operation of high-speed railway vehicles is met.

Description

technical field [0001] The invention relates to a bogie frame of a rail vehicle, in particular to a bogie frame of a trailer, and belongs to the technical field of rail vehicle manufacturing. Background technique [0002] The bogie is the running part of the rail vehicle, and the frame is the main structural part of the bogie. Various hangers and mounting seats for the primary and secondary suspension and braking of the bogie are welded on the frame. The acceleration of the vehicle plays a key role. [0003] With the rapid development of high-speed rail vehicles such as EMUs and high-speed rail, the requirements for structural strength, fatigue resistance and lightweight of the frame are getting higher and higher. The existing frame structure cannot meet the operating requirements of high-speed rail vehicles. Contents of the invention [0004] The main purpose of the present invention is to solve the above problems and deficiencies, and provide a rail vehicle trailer bogi...
