Transverse-drive bogie with built-in axle box

Abstract

A transverse-drive bogie with a built-in axle box comprises frames (1) arranged at the front and rear ends of axles (2) respectively, two ends of each axle are fitted with wheels (3) respectively, theframes are mounted on the axles through primary suspension devices (5) and axle boxes (4), each frame comprises two side beams (11), two cross beams (12) are arranged in the middle of the side beamsin parallel, both the frames and the axle boxes are arranged on the inner sides of the wheels (3), four basic brake devices (35) are symmetrically arranged at the bottom of the two side beams of eachframe, two driving motors (33) and two gearboxes (32) are fixedly connected to the two cross beams of each frame, output shafts of the two driving motors are parallel to the corresponding axle, and output shafts of the two driving motors are connected with the axles through the gear boxes respectively. The mature reliable scheme of transversely arranged motors is used herein, so that mounting space is reduced at the premise of meeting the transmission torque requirement; the gearboxes employ two-stage transmission, so that the size of the gearboxes is reduced and the lower limit is guaranteed.

Description

technical field [0001] The invention relates to a rail locomotive bogie, in particular to a laterally driven four-track flow-receiving axle box built-in bogie. Background technique [0002] At present, there are mainly three types of non-pantograph current receiving arrangements used by rail vehicles in the world, namely the upper grinding type, the lower grinding type and the side contact type. The end face of the side-contact contact rail rail head faces the running rail, and the contact shoe presses against the contact rail from the side, also known as side flow. It is used in the London subway in the UK, the Milan subway in Italy and the Malaysian light rail line. With the side current flow line, the installation position of the contact rail is higher than the rail surface, and the lower limit of the vehicle is squeezed. The traditional axle box external bogie cannot meet the limit requirements. The axle box built-in bogie can be applied to such a minimum limit because ...

AI Technical Summary

Problems solved by technology

[0003] However, since the axle box is installed on the inner side of the wheel, the space in the middle of the bogie is very small. The traditional horizontal arrangement of the motor is limited by the volume, and it is impossible to install a large-radius axle-disk brake device, and the brake caliper can only be installed under vibration conditions. Harsh bogie ends, and when installing wheel brakes or tread brakes, the weight of the bogie increases significantly, making it difficult to achieve a higher level of weight reduction
