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

Embodiment Construction

[0024] Such as figure 1 - Figure 5 As shown, an embodiment of the longitudinally driven axle box built-in bogie of the present invention includes a frame 3 installed on two axles 2, wheels 1 are respectively installed on the axles 2 outside the frame 3, and axles are installed on the inner sides of the wheels 1 at both ends of the axle 2. box 12, so that the frame 3 and the axle box 12 are arranged inside the wheel 1.

[0025] The frame 3 is formed by connecting two side beams 20 and the first and second beams 23 and 26 . The two frame side beams 20 are provided with a gear box hanging seat 24 and a motor hanging seat 21, the first beam 23 is provided with a traction seat 22, and the first and second beams 23, 26 are respectively provided with gear box anti-falling Seat 27, brake caliper mount 25. Two frame side beams 20 between the first and second crossbeams 23, 26 are respectively equipped with a traction motor 13 through the motor suspension seat 21, and the output sha...

Abstract

A longitudinal-drive bogie with built-in axle boxes comprises a frame (3) and axle boxes (12); the frame is formed by connecting two side beams (20) and first and second cross beams (23 and 26), boththe frame and the axle boxes are arranged within wheels (1), the two side beams are a traction motor (13) is mounted on each side beam through a motor hanger (21), output shafts of the two traction motors are perpendicular to axles (2), output shafts of the two traction motors are connected with the axles through couplings (16) and gearboxes (17), and the two traction motors are positioned betweenthe first and second cross beams (23 and 26); only one flange brake disc (18) is arranged on one axle and is fitted to a brake caliper (9) on the frame; a traction block (22) is arranged on the firstcross beam, the first cross beam is fixedly connected with one end of a traction pull bar through the traction block (22), and the other end of the traction pull bar is fixed to a vehicle body.

Description

technical field [0001] The invention relates to a rail locomotive bogie, in particular to a longitudinally driven 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 the axle box is insta...
