Problems solved by technology

[0004] However, the inventor found during the research process that the traditional bogie has a relatively large self-weight, which results in a large force on the wheel set, a large wear on the wheel and rail, and a large noise

specific Embodiment approach

[0096] The beam is made of cast aluminum alloy or other lightweight materials, and the cast mold can be made using additive manufacturing technology to reduce weight.

[0097] like Figure 9 As shown, the width of the end of the beam main body 21 facing the other beam unit 2 is larger than the width of the middle part of the beam main body 21 . The end face of the beam main body 21 facing the other beam unit 2 is called the inner end face. The first installation area and the second installation area are respectively located on the inner end face of the beam main body 21 , specifically arranged at both ends along the width direction of the inner end face.

[0098] A certain distance is left between the first installation area and the second installation area, so that there is a certain gap between the two beam connecting arms 22 for accommodating the pulling center pin in the bogie pulling device. The top of the traction center pin is connected with the vehicle body, and the b...

Abstract

An embodiment of the present application provides a bogie and a rail vehicle, and relates to a rail vehicle. The bogie includes: an axle; an axle box mounted on both ends of the axle through sealed bearings; a direct drive motor with a stator and a rotor and the end cover; the rotor is installed on the axle; the stator is installed on the end cover; the end cover is connected to the axle box; the dustproof retaining ring, one end is connected to the sealed bearing, and the other One end is connected to the end cap and forms a labyrinth seal with the end cap. In the embodiment of the present application, the rotor of the direct-drive motor is directly installed on the axle, and the driving force output by the direct-drive motor can be directly transmitted to the axle, eliminating the need to install a gearbox for transmitting the driving force in the traditional bogie, thereby facilitating the simplification of the structure of the bogie , to reduce the weight of the bogie, which is beneficial to realize light weight, reduce wear and tear on the wheel and rail, and is beneficial to reduce noise.

Description

technical field [0001] The present application relates to rail vehicle technology, and in particular, to a bogie and a rail vehicle. Background technique [0002] Rail vehicles are an important transportation link connecting cities, and have gradually become the main means of transportation in cities. Rail vehicles are also the main carrier for cargo transportation. The rail vehicle mainly includes: a car body and a bogie arranged under the car body. The bogie is used to carry the car body and realize the functions of running and steering. [0003] In the related art, a bogie includes structures such as a frame, a wheelset, a traction device, a lateral shock absorber, a vertical shock absorber, and a longitudinal stop. The lateral shock absorber is mainly used to buffer the lateral shock between the bogie and the car body, the vertical shock absorber is mainly used to buffer the vertical shock between the bogie and the car body, and the longitudinal stop is used to transmit...
