Multi-functional postpositional transfer case with three output shafts

Abstract

The invention discloses a multi-functional postpositional transfer case with three output shafts. The postpositional transfer case comprises a gearbox, a transfer case arranged at the front end of the gearbox, and a clutch arranged at the rear end of the gearbox, wherein an input shaft is fixedly mounted in the gearbox; two ends of the input shaft respectively extend into the clutch and the transfer case; the transfer case comprises a transfer case casing, a first output shaft, a second output shaft, a middle shaft and a third output shaft; a first gear is arranged on the input shaft; a second gear is in meshed connection with the first gear; a third gear is arranged on the middle shaft; the third gear is in meshed connection with the second gear; the input shaft and the first output shaft are arranged coaxially; the second output shaft, the middle shaft and the third output shaft are sequentially arranged coaxially; shifting gear sleeves are respectively connected to the first output shaft, the second output shaft and the third output shaft; corresponding external splines are arranged on the first gear and the third gear respectively; shifting devices are respectively connected to the shifting gear sleeves. The multi-functional postpositional transfer case disclosed by the invention is simple in structure and convenient to maintain, and can independently supply multiple power outputs.

Description

technical field [0001] The invention relates to a speed change device, in particular to a multifunctional three-head output rear transfer case. Background technique [0002] The existing rear-mounted transfer case has the defects of fixed speed ratio, which cannot be changed, complicated assembly, inconvenient maintenance, and large space occupation. Moreover, the transfer case can only output an additional power and cannot provide more power output. Can not arbitrarily put into gear shift operation, can't all put into gear and carry out transfer output when driving and parking, can't satisfy wider demand. Contents of the invention [0003] The purpose of the present invention is to provide a multifunctional three-head output rear-mounted transfer case to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a multifunctional three-head output...

Problems solved by technology

[0002] The existing rear-mounted transfer case has the defects of fixed speed ratio, which cannot be changed, complicated assembly, inconvenient maintenance, and large space occupation. Moreover, the transfer case can only output an additional power and cannot provide more power output. It is not possible to perform gear shifting operations at will, and it is not possible to engage gears for split output when driving and parking, which cannot meet a wider range of needs.
