Abstract

The invention provides a bogie for a rail vehicle and a rail vehicle, and relates to rail vehicle technology. The bogie used for rail vehicles includes: a frame, and the frame includes: two side beams and a beam connected between the two side beams, and the two sides of the beam are respectively provided with a wheel-to-axle box device; the wheel-to-axle box device includes a wheel Yes, the wheel set includes the axle and the wheels at both ends of the axle; the two ends of the side beam are provided with a first mounting seat, the primary suspension device is installed under the first mounting seat, and the primary suspension device is located at one end of the axle. By setting the first mounts at both ends of the side beam, the primary suspension device is installed under the first mount, and the primary suspension device is located at one end of the axle, and the primary suspension device is installed in an offset manner. Lower the installation height of the side beams, lower the installation height of the secondary suspension system, and then reduce the height of the car body floor above the bogie area, improving the convenience of passengers in the car.

Description

technical field [0001] The invention relates to rail vehicle technology, in particular to a bogie for a rail vehicle and a rail vehicle. Background technique [0002] The bogie is an important part of the rail vehicle, which is mainly used to support the car body and transmit various loads and forces between the wheel rail and the car body. In order to improve the curve passing ability of the rail vehicle, the bogie is usually equipped with a hinged structure, so that the rail vehicle can make a slewing motion around the handover point. [0003] In the prior art, the bogie includes: two side girders, a cross beam is connected between the two side girders, and the cross girder is welded by steel pipes; two ends of the side beams are provided with wheel sets, and the wheel sets include: an axle and The wheels are press-fitted on both ends of the axle, and the axle box is also sleeved with an axle box. A series of suspension devices are installed directly above the axle box. T...
