Left comer tooth 10, right axle shaft 13 is through the basin tooth 8 and is installed with right corner tooth 11, the left comer tooth 10, right corner tooth 11 and the planet
Tooth 9 forms the engagement of differential closed loop, it is characterised in that: the basin tooth 8 is extended with splined shaft canister portion 8- along 13 direction of right axle shaft
1, the conjunction gear 15 opposite with the splined shaft canister portion 8-1 is installed on the right axle shaft 13, and further including can be to the splined shaft
Canister portion, conjunction gear 15 synchronize the combined cover 14 of circumferential locking and control the combined cover 14 to the splined shaft canister portion 8-1, combination
Tooth 15 synchronizes circumferential locking and releases the differential lock shift fork 16 of locking；The basin tooth 8 is connected to input by gear shift
On axis 1, which includes clutch cover 7 and the shift reinforcement shift fork 20 for controlling the clutch cover 7.
Further, the conjunction gear 15 includes spline shaft identical with the section splined shaft canister portion 8-1, the knot
Trap 14 slides axially on the splined shaft canister portion 8-1, when need to synchronize circumferential direction to the splined shaft canister portion 8-1, conjunction gear 15
When locking, which cooperates with the splined shaft canister portion 8-1, spline shaft simultaneously.
Further, differential lock manipulation hand 18 is fixed on the differential lock shift fork.
Further, the gear shift includes the same quick pinion gear 2 being located on the input shaft 1, low speed
It is big to be set with quick gear wheel 4, low speed on the deboost axle 6 for pinion gear 3, the deboost axle 6 with 8 engaged transmission cooperation of the basin tooth
Gear 5, the quick gear wheel 4, low speed gear wheel 5 are corresponding to engage cooperation with the quick pinion gear 2, low speed pinion 3, described
7 axial sliding fit of clutch cover is on the deboost axle 6, and the clutch cover 7 controls the quick gear wheel 4, low speed gear wheel 5
It is covered admittedly with the deboost axle 6 respectively.
Further, the quick gear wheel 4, low speed gear wheel 5 are integrally extended with to 7 direction of clutch cover respectively
One spline housing portion 4-1, the second spline housing portion 5-1, the clutch cover 7 by spline fitted on the deboost axle 6, and the clutch
It covers 7 both ends and is respectively provided with the internal splined hole that can cooperate with first spline housing portion 4-1, the second spline housing portion 5-1.
Further, shift control handle 19 is connected on the shift reinforcement shift fork 20.
The structure and working principle of the utility model middle gear gear is as follows: the power of motor output is passed to input shaft
