Abstract

A multi-gear variable speed device for vehicles includes a power input shaft, two countershafts, a reverse idle gear shaft and a power output shaft. The shafts are paralleled each other. The power transmission line of the forward gear consists of an input shaft gear, a countershaft gear and an output shaft gear. The power transmission line of the reverse gear consists of an input shaft gear, a reverse duplex gear, a countershaft gear and an output shaft gear.

Description

technical field [0001] The invention belongs to the technical field of transmissions, and relates to a multi-speed transmission for vehicles. The international patent classification number is: F16H3 / 08. Background technique [0002] For the vehicle transmission, the transmission ratio of the first gear pair and the reverse gear pair are the largest, so the torque transmitted by these two pairs of gear pairs is the largest, and the working stress on the teeth is also the largest, usually the transmission assembly Weaknesses in strength. [0003] In existing similar speed changers, the mode that arranging the reverse gear pair usually adopts is: first: borrow a gear drive gear as the reverse drive gear or arrange a gear separately in the assembly as the reverse drive gear. Second: The reverse gear driving gear meshes with a reverse gear idler gear, and the reverse gear idler gear meshes with a reverse gear output gear at the same time to realize the transmission of reverse g...
