Description
Technical field
The present invention relates to the front driving axle of a kind of pair of drive axle, refer to output mechanism after the front driving axle timesharing particularly.
Background technology
The output mechanism of the front driving axle of two drive axles generally is to adopt a thru shaft structure.One end of this thru shaft links to each other with interaxle differential, and an other end is given rear driving axle by output flange and transmission shaft with the part takeoff output that driving engine sends, thereby guarantees that rear driving axle participates in vehicular drive.But, there is following problem in this structure: when vehicle only needs single bridge driving can satisfy the dynamic property requirement, driving between front driving axle and the rear driving axle can't be disconnected, rear driving axle still participates in driving, can increase the wearing and tearing of rear driving axle like this, the car load fuel economy is descended, and carbon emission increases, and is unfavorable for environmental protection.
Summary of the invention
The objective of the invention is to overcome the existing in prior technology deficiency, output mechanism after a kind of front driving axle timesharing is provided, when vehicle does not need rear driving axle to participate in driving, can not disconnect transmission of power.
For achieving the above object, output mechanism after the designed front driving axle timesharing of the present invention, comprise interaxle differential, transmission shaft and output flange, described transmission shaft is formed by connecting by front propeller shaft and rear propeller shaft, described front propeller shaft and rear propeller shaft junction are socketed with power-transfer clutch, the front end of described front propeller shaft and interaxle differential engagement, rear end and clutches engaged, the front end of described rear propeller shaft and clutches engaged, rear end and output flange engagement also are provided with the control mechanism of stirring power-transfer clutch on the described power-transfer clutch.
Preferably, described control mechanism is provided with shift fork, and described clutch Outside has the draw-in groove that is complementary with shift fork.Like this, the power transmission between the transmission shaft of front and back can be stirred power-transfer clutch by shift fork and realizes with disconnecting.
Preferably, the two ends of described front propeller shaft and rear propeller shaft are provided with male splines, and described power-transfer clutch is the inner loop configuration that is provided with spline, and described power-transfer clutch is meshed by the male splines of female splines with front propeller shaft and rear propeller shaft end.Like this, when stirring power-transfer clutch by shift fork, power-transfer clutch both can be meshed with the end of two transmission shafts simultaneously, again can be only with the end of front propeller shaft or only be meshed with the end of rear propeller shaft.
Particularly, be connected with bearing by axle between described front propeller shaft and the rear propeller shaft.Like this, between two transmission shafts certain clearance is arranged, both can rotate mutually, zerofriction force in the time of can guaranteeing again between two transmission shafts, to rotate mutually.
Be connected with three kinds of modes between two transmission shafts:
Preferred version one, described front propeller shaft and axle connect as one, and the bearing outer by axle is connected with rear propeller shaft.
Preferred version two is provided with an axle in the axle center between described front propeller shaft and the rear propeller shaft, the bearing outer by axle connects.
Preferred version three, described rear propeller shaft and axle connect as one, and the bearing outer by axle is connected with front propeller shaft.
Beneficial effect of the present invention is: output mechanism after the front driving axle timesharing of the present invention, the power transmission between the drive axle of front and back realizes by the power-transfer clutch and the control mechanism thereof that are sleeved on the transmission shaft with disconnection.The present invention is in the vehicle traveling process of two drive axles, both can realize takeoff output by power-transfer clutch and control mechanism, can disconnect takeoff output again, thereby guarantee outputting power when vehicle needs rear-axle drive, when vehicle does not need rear-axle drive, disconnect takeoff output; Efficiently solve the drawback that rear driving axle must participate in driving, reduced the wearing and tearing of rear driving axle, improved the car load fuel economy greatly, reduced carbon emission.Structure of the present invention is ingenious, and repacking is got up fairly simple, does not need to change the inner structure of existing double drive axle basically, suitable applying.

The specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Output mechanism after the front driving axle timesharing as shown in fig. 1 comprises interaxle differential 1, transmission shaft 2 and output flange 3, and transmission shaft 2 is formed by connecting by front propeller shaft 2.1 and rear propeller shaft 2.2.Front propeller shaft 2.1 is socketed with power-transfer clutch 4 with rear propeller shaft 2.2 junctions.The two ends of front propeller shaft 2.1 and rear propeller shaft 2.2 are provided with male splines, and power-transfer clutch 4 is the inner loop configuration that is provided with spline.The front end male splines of front propeller shaft 2.1 and the engagement of the female splines of interaxle differential 1, the rear end male splines of front propeller shaft 2.1 and the engagement of the female splines of power-transfer clutch 4.The front end male splines of rear propeller shaft 2.2 with the engagement of the female splines of power-transfer clutch 4, mesh with output flange 3 rear propeller shaft 2.2 rear ends.Also be provided with the control mechanism 5 of stirring power-transfer clutch 4 on the power-transfer clutch 4.Control mechanism 5 is provided with shift fork 5.1, and there is the draw-in groove 4.1 that is complementary with shift fork 5.1 power-transfer clutch 4 outsides.
Be connected with bearing 7 by axle 6 between front propeller shaft 2.1 and the rear propeller shaft 2.2.
Be connected with three kinds of modes between two transmission shafts:
Scheme one, as shown in Figure 2, front propeller shaft 2.1 connects as one with axle 6, is connected with rear propeller shaft 2.2 by axle 6 outer bearings 7.
