A rear wheel drive system for an electric bus

Abstract

The invention belongs to the technical field of driving, in particular to a rear wheel drive system for an electric bus. The system includes an electric motor, a drive shaft, a torque identification mechanism, a cone-tooth assembly, an actuator, a transmission mechanism, wherein the torque identification mechanism moves the second centrifugal plate in the actuator in a direction away from the third rotational shaft by identifying the rapid acceleration process of the bus, such that the limiting strip cannot limit the first centrifugal plate, and the first centrifugal plate is disengaged from the centrifugal plate groove under the centrifugal force; Such a design is intended to allow the first centrifugal plate to move away from the centrifugal plate bath for a short period of time, the speed of the bus will not be greatly increased immediately, so that passengers who are easy to get carsick can adapt to the rapid acceleration process of the bus, thus preventing passengers who are easyto get carsick from having carsickness, and ensuring the safety of passengers who are easy to get carsickness. The invention has the advantages of simple structure and good use effect.

Description

technical field [0001] The invention belongs to the field of drive technology, in particular to a rear wheel drive system used by an electric bus. Background technique [0002] At present, the country is vigorously promoting low-carbon travel and green travel, so now the buses in the city are upgraded from the original gasoline-burning buses to pure electric buses; however, after the upgrade, the starting and driving methods of pure electric buses are similar to burning gasoline The buses are different, especially in the process of starting and accelerating; for gasoline-burning buses, there will be a process of shifting gears during starting and accelerating, while gasoline-burning buses will take about two seconds when changing gears In the interval of about two seconds, passengers will be more likely to adapt to the acceleration process of a gasoline-burning bus, which is beneficial to passengers who are more prone to motion sickness; but in the process of starting and ac...

Problems solved by technology

[0002] At present, the country is vigorously promoting low-carbon travel and green travel, so now the buses in the city are upgraded from the original gasoline-burning buses to pure electric buses; however, after the upgrade, the starting and driving methods of pure electric buses are the same as burning gasoline. The buses are different, especially in the process of starting and accelerating; for gasoline-burning buses, there will be a process of shifting gears during the process of starting and accelerating, while gasoline-burning buses will have about two seconds when changing gears In the interval of about two seconds, passengers will be more likely to adapt to the acceleration process of a gasoline-burning bus, which is beneficial to passengers who are more prone to motion sickness; but in the process of starting and accelerating a pure electric bus There is a gap of two seconds, so it is not good for passengers who are more prone to motion sickness
