Beneficial effect of the present invention:
1, angle of the present invention transmission speed variator, its input shaft and output shaft are arranged vertically, thus can save longitudinal arrangement space of motor and speed changer, and vehicle rear overhang is shortened, puts little after Ackermann steer angle, cruising characteristic is good.
2, angle of the present invention transmission speed variator, input shaft is arranged in the middle part of output shaft, makes the layout of motor closer in vehicle rear axle center, thus increases the space of motor lateral arrangement, the type selecting of favourable motor, as selected the volume more more motor of vat number.
3, angle of the present invention transmission speed variator, because the plane orthogonal at output gear shaft and jack shaft shaft axis place is in the plane at input shaft and output shaft shaft axis place, therefore be assembled to after on vehicle, its output gear shaft and input shaft in the vertical direction stagger certain distance, and transmission shaft can be made to keep level connection joint.
4, angle of the present invention transmission speed variator, unclamping input shaft supporting sleeve can pull down input shaft from gearbox casing, and easy accessibility can improve the working efficiencies such as debugging, maintenance.
Accompanying drawing explanation
Fig. 1 is the structural representation of angle of the present invention transmission speed variator,
Fig. 2 is the structural representation of transfer case.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the present embodiment angle transmission speed variator, comprise gearbox casing 1, described gearbox casing 1 arranges the output shaft 2 be parallel to each other and jack shaft 3, the synchronizer 5 described output shaft 2 being provided with driven power shift gear 4 and coordinating with driven power shift gear 4, described jack shaft 3 is provided with the active power shift gear 6 engaged with driven power shift gear 4, also comprise the input shaft 7 vertical with output shaft 2, the end winding support of described input shaft 7 is connected with the drive bevel gear 8 coaxial with it, the middle part of described output shaft 2 is provided with the driven wheel of differential 9 and normally engaged driving gear 10 that are rotatably assorted with it, described driven wheel of differential 9 is fixedly connected with normally engaged driving gear 10, described jack shaft 3 is provided with the driven constant mesh gear 11 with its secure fit in a circumferential direction, described drive bevel gear 8 and driven wheel of differential 9 engage, described normally engaged driving gear 10 and driven constant mesh gear 11 engage.
