80km/h speed class b-type subway vehicle bogie

Abstract

The invention discloses an 80km / h speed class B-type subway vehicle bogie, which belongs to the field of subway vehicle bogies. The subway vehicle bogie consists of a framework, a driving device arranged on the framework and used for transmitting a driving force, a primary suspension, a secondary suspension arranged on the framework and used for supporting a vehicle body, a traction device for connecting the framework and the vehicle body and transmitting a traction force and a braking force, a side rolling resistant device for connecting the framework and the vehicle body and inhibiting the side rolling tendency of the vehicle body, a base braking device arranged on a side beam of the framework and used for transmitting power, and a third rail current receptor arranged on the side beam of the framework and playing a role in current reception. The subway vehicle bogie has the advantages of excellent dynamic performance, good comfort of passengers, low noise, reliable strength, high utilization rate of traction and adhesion, good running performance, high safety and reliability indexes, and excellent maintenance performance.

Description

technical field [0001] The invention relates to the field of bogies of subway vehicles, which is a B-type subway bogie (maximum axle load is 14t) of 80km / h speed grade, and is suitable for B-type subway vehicles of 80km / h speed grade. Background technique [0002] In the existing technology, the design principles of high reliability, light weight, maintenance-free, and parts replacement are adopted in the bogie technology of 80km / h speed class subway vehicles; all motor suspension structures are used to reduce the unsprung weight to meet the high-speed running performance , and a large number of experimental verification work has been carried out, and its safety and reliability have been verified by operation. [0003] At present, there are many studies on bogies. For example, Lu Haiying (Railway Vehicles, Vol. 41, No. 6, June 2003) reviewed "Research on Design and Research of B-type Urban Rail Transit Vehicle Bogies"; Zhou Rui (Design and Manufacturing, 2004) The "Scheme D...
