Classification of vehicle gear transmission works
A pair of meshing gears, a low-gear Z1 = 20, large gear Z2 = 40, at the same time turn the small gear ring, the big gear turn half circle. Clearly, when the small gear is the gear, its speed by a large gear reduced output when; if the big gear is the gear, its speed by a small gear output would be increased. This is the principle of variable speed gear transmission.

1, three-axis five-speed Transmission There are five forward gears and one reverse gear, from the shell, the first shaft (input shaft), intermediate shaft, second shaft (output shaft), reverse gear shaft, the shaft gear, control institutions, composed of several parts.
A, the first shaft axis and the first axis often the first gear as a whole, is the transmission Power Input shaft. The first axis of the front of the spline interpolation of the clutch disc hub.
B, the intermediate shaft in the middle axis system are (or fixed equipment) has six gears, which rotate as a whole. Top gear with a gear shaft meshing often called the intermediate shaft gear often, from the clutch input shaft power through a pair of regular reached the intermediate shaft gear on the gear. Turn back the gear for the intermediate shaft, said third gear, second gear, reverse gear, a file and the five-speed gear.
C, second shaft in the second axis, with three solid through the spline hub spline through the bearing axis stall installed 2 gear. One front to back, in the first and second spline hub with third gear and second gear between the gears in the second and third between the spline hub with a file and five-speed gear, they were all with the middle axis meshing gears with the corresponding file. Spline hub in three sets, respectively, are the interface with a set of internal spline, and with synchronous body. Through the joint sleeve to move about, can make the spline gear on the hub and adjacent to the interface ring gear connected to the power transmission gear on the second axis. Which put on the second bonding system also has reverse gear. Front axle shaft second gear into the center of a hole, with needle bearings between the two. The second axis through the flange and the universal back-end drives connected.
D, reverse shaft reverse shaft interference fit pressure mounted on the shell corresponding shaft hole. Reverse gear bearing looper through the shaft in reverse.
2, the dynamic power transfer case files
A, a file input shaft axis the first round of regular rodent intermediate shaft intermediate shaft gear first gear first gear shaft gear 2nd a file synchronizer engagement ring gear engagement sets output of the second shaft
B, second gear input shaft of the first axis of regular rodent wheel intermediate shaft intermediate shaft gear second tranche second gear shaft second gear second gear synchronizer engagement ring gear engagement sets output of the second shaft
C, third gear shaft input shaft the first round of regular rodent intermediate shaft intermediate shaft third gear third gear gear gear second third gear shaft synchronizer engagement ring gear engagement sets output of the second shaft
D, fourth gear first gear input shaft First round of regular rodent gear engagement ring gear shaft fourth gear 3, fourth gear synchronizer engagement sets second shaft output (direct file)
E, five-speed input shaft of the first axis of regular rodent wheel intermediate shaft intermediate shaft gear fifth file the second-axis five-speed gear 5 file synchronizer engagement ring gear engagement sets output of the second shaft (overdrive)
F, reverse gear shaft input shaft the first round of regular rodent intermediate shaft intermediate shaft reverse gear reverse gear reverse axis the second axis, the second shaft reverse gear reverse gear engagement reverse synchronizer ring gear engagement sets second output shaft
3, two-axis transmission
Two-axle transmission mainly by the input and output two-axis component. Compared with the traditional three-axis transmission, due to eliminating the intermediate shaft, in general, only after a pair of gear stalls can be transmitted to the input shaft of the power output shaft, so transmission efficiency is higher some; the same as any of the files are have to go through a pair of gears, so the transmission efficiency of any file they are not as direct file transmission axis transmission efficiency.
