Embodiment 1

[0020] Embodiment 1: see Figure 1 to Figure 3 , a bogie frame of an engineering testing vehicle, comprising two box-shaped side beams 1 and two cross beams 2, the two side beams 1 and two cross beams 2 are fixedly connected to each other to form an H-shaped frame body, The crossbeams 2 are hollow structures, and an auxiliary beam 3 is fixed between the inner sides of the two crossbeams 2, which meets the strength and rigidity requirements of the framework and realizes the lightweight design requirements. The middle part of the side beam is concaved to form a concave part for installing the secondary spring seat, which reduces the distance between the upper plane of the secondary spring group and the rail surface, and reduces the height of the center of gravity of the vehicle.

[0021] The auxiliary beam adopts a hollow steel pipe, on which the fixing seat 12 used for the limitation of the traction beam when the bogie is hoisted as a whole is welded and installed. superior. ...

Abstract

The invention discloses an engineering detection vehicle bogie frame. The engineering detection vehicle bogie frame comprises an H-shaped frame body composed of two side beams of a box-shaped structure and two cross beams of a hollow structure. Hollow auxiliary beams are fixed between the inner sides of the two cross beams. The middles of the side beams are sunken to form sunken parts used for mounting secondary spring seats. The outer sides of the middles of lower cover plates of the side beams protrude outward to form vertical oil pressure shock absorber seats. According to the trailer engineering detection vehicle bogie frame suitable for tread brake, the side beams are of the box-shaped structure, the cross beams and the auxiliary beams all adopt hollow steel pipes, thus the whole weight of the frame is effectively decreased while strength is guaranteed, and the purpose that a vehicle body is lightweight is achieved.

Description

technical field [0001] The invention relates to a bogie frame of an engineering testing vehicle, which belongs to the technical field of track testing vehicle manufacturing. Background technique [0002] The bogie is the running system of rail vehicles. The bogie frame is the main part of the bogie. Its function is to carry the weight of the car body, transmit traction, braking force, vibration reduction, guidance, etc. The overall structure of the frame is very important for the safe operation of the track inspection vehicle. play a vital role. The beam of the existing engineering inspection vehicle frame is a box-shaped beam structure, and the basic brake type is a shaft disc brake. The frame structure is complex, the welding volume is large, the weight is heavy, the manufacturing cost of the bogie is high, and it is not conducive to the weight reduction of the bogie itself. design. Contents of the invention [0003] Aiming at the defects existing in the prior art, the...
