Abstract
The invention relates to an integral structure of a transfer case and a middle axle, and belongs to the automobile manufacturing industry. The integral structure is characterized in that a planet carrier is respectively meshed with a gear ring and a sun gear by virtue of planet gears, the gear ring is connected with a driving cylindrical gear by virtue of a spline, a driven cylindrical gear is connected with a straight bevel gear planetary mechanism by virtue of a spline, the sun gear is connected with a through shaft by virtue of a spline, a differential lock I is fixedly connected with the through shaft, the gear ring is connected with the through shaft by virtue of the differential lock I, a differential lock II is connected with a front-axle input shaft, and the straight bevel gear planetary mechanism is connected with a speed reducer. The integral structure disclosed by the invention has the advantages that the integral structure is compact in structure, simple in process and light in weight, facilitates the arrangement of a transmission system of a finished automobile, and can ensure the longitudinal through radius of an off-road vehicle to be improved, thereby improving the cross-country performance of the off-road vehicle.
Description
Technical field
The invention belongs to auto manufacturing, relate in particular to a kind of part-time case and jackshaft integrative-structure, be applicable to the 6x6 cross country car.
Background technology
The 6x6 cross country car is realized the front and back transmission of engine power by part-time case, and the part-time case of most of vehicle all is arranged in the change speed gear box back, this arrangement be difficult to be realized the car load scheme arrangement and is satisfied the cross-country demand of vehicle for the overland vehicle of structural requirement compactness.
Summary of the invention
The invention provides a kind of part-time case and jackshaft integrative-structure, because the part-time case of vehicle is arranged in the change speed gear box back, cause the problem that is difficult to satisfy the overland vehicle realization car load layout of structural requirement compactness and satisfies the cross-country demand of vehicle to solve.
The technical scheme that the present invention takes is: pinion carrier is meshed with gear ring and sun wheel respectively by planetary wheel, wherein gear ring by spline be connected with cylindrical wheel initiatively, driven cylindrical gear is connected with the spur bevel gear wheel planetary mechanism by spline, sun wheel is connected with thru shaft by spline, differential locking-device one is captiveed joint with thru shaft, gear ring is by differential locking-device one and thru shaft interlocking, differential locking-device two is connected with the propons input shaft, and the spur bevel gear wheel planetary mechanism is connected with retarder.
Advantage of the present invention is a novel structure, gets and replaced independently transfer case assembly, and be jackshaft design all-in-one-piece structure with part-time case with connecting bridge, realizes full-timely driving entirely, two overlap difies all the forced locking function; The output interface of bridge also can reasonably distribute moment of torsion and the rotating speed of transporting to propons, jackshaft and back axle before, during and after having.Compact conformation, technology are simple, in light weight, help the layout of car load driving system and can improve overland vehicle vertically by radius, improve the off-road capability of vehicle.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Pinion carrier 1 is meshed with gear ring 2 and sun wheel 5 respectively by planetary wheel, wherein gear ring 2 by spline be connected with cylindrical wheel 3 initiatively, driven cylindrical gear 6 is connected with spur bevel gear wheel planetary mechanism 7 by spline, sun wheel 5 is connected with thru shaft 10 by spline, differential locking-device 1 is captiveed joint with thru shaft 10, gear ring 2 is by differential locking-device one and thru shaft interlocking, differential locking-device 28 is connected with propons input shaft 11, and spur bevel gear wheel planetary mechanism 7 is connected with retarder 9.
Power is through the pinion carrier 1 input gear ring 2 and sun wheel 5 outputs of cylindrical wheel planet row mechanism, wherein gear ring 2 is distributed to front axle assy and jackshaft main reduction gear 9 after active cylindrical wheel 3, driven cylindrical gear 6 are input to spur bevel gear wheel planetary structure 7, and sun wheel 5 directly outputs power to back axle assembly by thru shaft.The function that cylindrical wheel planet row mechanism that is made up of pinion carrier 1, gear ring 2, sun wheel 5 etc. and spur bevel gear wheel planetary mechanism 7 not only have distribute torque also has the function of differential.Differential locking-device 1, differential locking-device 28 have the function of differential forced locking.
