Abstract

The invention discloses a speed change assembly integrating a reverse gear. The speed change assembly comprises a power input shaft, a power output shaft, a reverse gear transmission chain and a shared driven gear, wherein the power output shaft is in gear transmission fit with the power input shaft. The reverse gear transmission chain can be matched with the shared driven gear in a joint transmission or separation mode; the shared driven gear is arranged on the power output shaft in the manner of being in a joint transmission mode with the power output shaft; the shared driven gear is matched with one forwarding gear driving gear in a transmission or transmission stop mode. According to the speed change assembly, the structure that the reverse gear and one forwarding gear share the same driven gear is adopted, through reasonable optimization of meshing and arrangement of the gears, the arrangement relationship between components is fully utilized, the reverse gear structure is arranged inside a speed changer, and therefore the speed change structure with the internally arranged reverse gear is achieved through the components in limited number, and the original forwarding gear is not omitted. Thus, compared with an existing independent reverse gear structure, the speed change assembly has the advantages that the speed changer is compact in structure, high in integrity, good in operation stability, attractive in appearance and suitable for mini-sized motor vehicles.

Description

technical field [0001] The invention relates to a motor vehicle component, in particular to a speed change assembly with an integrated reverse gear. Background technique [0002] A motor vehicle is a vehicle that is driven or towed by a power plant (including electric and fuel gas vehicles) and travels on the road, generally including a power plant, a transmission, and a wheel frame assembly; the transmission transmits the output power of the power plant to the Wheels are used to drive the vehicle. In the prior art, the main function of the speed changer is to change the transmission ratio, and for a motor vehicle with more than two wheels, it is generally necessary to set a reverse gear. [0003] In the prior art, multi-speed transmissions have good adaptability to driving road conditions and can shift gears against different resistances, so that the power output of the power unit can match the driving road conditions to a certain extent, so they are widely used. However,...
