Technical field
The utility model relates to a kind of automobile power transmission and transfer device, relates in particular to a kind of three drive axle transfer case of automobile that are applied in 6 * 6 driving vehicles.
Background technology
Transfer case of automobile is a pinion unit, and its input shaft second directly or through universal driving device and change-speed box links, and the output shaft of part-time case then has some, is connected with each drive axle through universal driving device respectively.Fig. 1 is the decomposition texture scheme drawing of the transfer case of automobile on existing 6 * 6 driving cars, and this part-time case comprises the part-time case housing, power input shaft, tween drive shaft, propons power take-off shaft, jackshaft power take-off shaft and back axle power take-off shaft.Power input shaft is connected with the output shaft of Automotive transmission, is with high retaining input gear and low retaining input gear on this power input shaft respectively.Be with high retaining power shift gear, gearshift combined cover, low retaining power shift gear and intermediate gear on the tween drive shaft respectively.Usually between propons power take-off shaft and jackshaft power take-off shaft, be provided with diff, the driven gear engagement on said intermediate gear and the diff, diff can be realized the shaft space difference speed of two output shafts.When the height retaining power shift gear engagement on height retaining input gear and the tween drive shaft, power reaches propons output shaft and jackshaft output shaft respectively by power input shaft, high retaining power shift gear, realizes high gear output.Stir the shift fork in the gearshift combined cover, make the low retaining power shift gear engagement on low retaining input gear and the tween drive shaft, power reaches propons output shaft and jackshaft output shaft respectively by power input shaft, low retaining power shift gear, realizes low gear output.In this process, said back axle output shaft directly is communicated with power input shaft all the time, and this output shaft can't be realized shaft space difference speed with preceding, jackshaft output shaft, makes the back axle output shaft to have the different rotating speed ratio with propons output shaft and jackshaft output shaft.
In addition; The diff of existing application on part-time case generally adopts the cylindrical wheel planetary driving device, and the locking of diff and separation need artificial intervention, and its locking form is a forced locking; Need be at extra assembling differential locking-device and gap bridge case, complex structure and increased manufacturing cost.
The utility model content
The utility model aims to provide a kind of three drive axle transfer case of automobile, and this part-time case can make back axle output shaft and propons, jackshaft output shaft realize shaft space difference speed.
In order to address the above problem, the three drive axle transfer case of automobile of the utility model comprise housing, power input shaft, tween drive shaft, propons power take-off shaft, jackshaft power take-off shaft and back axle power take-off shaft; Be arranged with high retaining input gear and low retaining input gear on the said power input shaft respectively, be arranged with high retaining power shift gear, gearshift combined cover, low retaining power shift gear and intermediate gear on the said tween drive shaft respectively; Be provided with first diff between said propons power take-off shaft and the jackshaft power take-off shaft; Driven gear on this first diff and the engagement of said intermediate gear; Wherein: be provided with second diff between said power input shaft and the said back axle power take-off shaft, driven gear on this second diff and the engagement of said intermediate gear.
Preferably, said first diff and said second diff are castellated diff.
Through second diff is set between back axle output shaft and power input shaft; This second diff and first diff cooperatively interact; A takeoff output control that is used for back axle, a takeoff output control that is used for propons, jackshaft can realize drive axle shaft space difference speed before, during and after the vehicle.Make back axle output shaft and propons output shaft and jackshaft output shaft can have the different rotating speed ratio.
Description of drawings
Fig. 1 is the decomposition texture scheme drawing of three drive axle transfer case of automobile of the prior art;
Fig. 2 is the decomposition texture scheme drawing of the three drive axle transfer case of automobile of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done description further.
Fig. 2 is the decomposition texture scheme drawing of the three drive axle transfer case of automobile of the utility model; This three drive axles transfer case of automobile comprise two can snapping housing 1, be provided with power input shaft 2, tween drive shaft 3, propons power take-off shaft 4, jackshaft power take-off shaft 5 and back axle power take-off shaft 6 in the housing.Be arranged with high retaining input gear 21 and low retaining input gear 22 on the said power input shaft 2 respectively; The through hole of one end from housing 1 of this power input shaft 2 stretches out; Be set with nut 25, input flange 26, input flange end cap 27, bearing 28 on it; The other end is connected with an end of second diff 8, and the other end of this second diff 8 is connected with back axle power take-off shaft 6.The through hole of one end from housing 1 of said back axle power take-off shaft 6 stretches out, and is set with bearing 68, back axle output flange end cap 67, back axle output flange 66 and nut 65 on it.Be arranged with tween drive shaft front end cover 38, high retaining power shift gear 31, gearshift combined cover 33, low retaining power shift gear 32, intermediate gear 34, bearing and tween drive shaft rear side housing 37 on the said tween drive shaft 3 respectively.One end of said propons power take-off shaft 4 is stretched out by the through hole in the housing 1; Be arranged with nut 45, propons output flange 46, propons output flange end cap 47 and bearing 48 on it; The other end is connected with an end of first diff 7; The other end of this first diff 7 is connected with an end of jackshaft power take-off shaft 5, and the other end of this jackshaft power take-off shaft 5 is arranged with bearing 58, jackshaft output flange end cap 57, jackshaft output flange 56 and nut 55.
This part-time case adopts 5 Structural Design of Shaft, and 3 clutch ends are arranged, and all adopts end face tooth flange connection, can realize driving 1: 1: 1 takeoff output pattern of 3 drive axles of pattern vehicle to 6 * 6.This part-time case is designed with two difies, a takeoff output control that is used for back axle, and a takeoff output control that is used for propons, jackshaft can realize drive axle shaft space difference speed before, during and after the vehicle.
