Rapid-distribution transfer case

Abstract

The invention discloses a rapid-distribution transfer case. The rapid-distribution transfer case comprises a case body, an input gear shaft, a first output shaft and a second output shaft, wherein the input gear shaft, the first output shaft and the second output shaft are installed in the case body. The rapid-distribution transfer case further comprises a first gear, a second gear, a first bearing, a second bearing and a movable shifting fork mechanism. The first gear is connected with the first output shaft through the first bearing, and the second gear is connected with the second output shaft through the second bearing. The movable shifting fork mechanism comprises a shifting rod, a shifting fork shaft, a first shifting fork mechanism body and a second shifting fork mechanism body. The two ends of the shifting fork shaft (11) are arranged in a hole in a front plate and a hole in a back plate of the case body, the shifting rod is connected to the shifting fork shaft, and the first shifting fork mechanism body and the output shafts achieve rapid distribution of power. It is avoided that the power of a motor is selectively output in a frequent coupling connection and separation complex manner.

Description

technical field [0001] The invention relates to a novel transfer case, in particular to a power selectable transfer case capable of rapid shunt flow transmission. technical background [0002] At present, the power transmitted from the motor generally passes through the transfer case (gearbox), and the gear on the input shaft meshes with the gears on the two output shafts to output the power, and the output end is connected to the outside world through a coupling. figure 1 It is a schematic diagram of the structure of the existing transfer case. The transfer case includes parts such as the case body 1, the input gear shaft 2, the output shaft I3, the output shaft II4, the gear I5, and the gear II6. The transfer case passes through the input gear shaft 2 The shaft end of the shaft is connected to the power transmitted by the motor, and the power is output along two routes through gear I5 and gear II6 at the same time. The shaft ends of output shaft I3 and output shaft II4 are...
