Accompanying drawing explanation
Labelling in the content expressed every width accompanying drawing in this utility model description below and figure is briefly described:
Fig. 1 is vehicular transmission shaft structural representation；
Labelling in above-mentioned figure is: 1, leading portion power transmission shaft；2, back segment power transmission shaft；3, bearing block；4, bearing；5, spline housing is connected；6, hole back-up ring；7, guard shield.
Detailed description of the invention
As shown in Figure 1, power transmission shaft body is made two sections by this utility model, it is divided into leading portion power transmission shaft 1 and back segment power transmission shaft 2, solve single power transmission shaft long, processing cost is higher, and the problem that power transmission also can not meet transfer motion power requirement, leading portion power transmission shaft 1 and back segment power transmission shaft 2 connect by connecting spline housing 5, connect spline housing 5 to be fixed in bearing block 3 by bearing 4, improve gear-box drive axle supporting device and bear the ability of load, bearing 4 is difficult to corrupted, the needs that power increases, ensure that the dependability of change speed gear box, extend service life.
In order to preferably protect intermediate propeller shaft; drive shaft guard 7 is added outside power transmission shaft; guard shield 7 one end is fixed on bearing block 3; the other end is fixed on car body; adding mudhole above this external drive shaft guard 7, mudhole is in the bottom surface of drive shaft guard 7, and the most preferably infiltering, the muddy water passed in axle is convenient to flow out; thus preferably protect power transmission shaft, extend the service life of power transmission shaft.
Bearing 4 is band dust cap deep groove ball bearing 4, it is possible to preferably adapts to the running of power transmission shaft, is provided with hole back-up ring 6 between leading portion power transmission shaft 1 and back segment power transmission shaft 2, has buffering and the effect filled, improves the reliability of supporting construction.
This utility model system of vehicle transmission axle construction may apply on four-wheel tractor, it is longer to there is wheelbase in medium-sized four-wheel drive tractor, the power transmission shaft that propons and back axle connect, a piece power transmission shaft is long, the problem that processing cost is higher, utilizes two-part leading portion power transmission shaft 1 and back segment power transmission shaft 2 to replace a power transmission shaft, front end is connected with propons by spline housing, middle bearing bracket 3 is fixed on above gear box casing, and rear end is connected with back axle by spline housing so that transmission is more reliable and more stable.
Operation principle: back segment power transmission shaft 2 is linked together with change speed gear box back axle spline by part spline housing, bearing block 3 is bolted to above chassis by part, band dust cap deep groove ball bearing 4 is fixed on above part bearing block 3, connect spline housing 5 and be fixed on above bearing block 3, leading portion power transmission shaft 1 and part back segment power transmission shaft 2 connect spline housing 5 by part and link together, it is achieved the middle supporting connected and transmission function；Leading portion power transmission shaft 1 is linked together with propons spline by part spline housing, it is achieved that rear axle power is delivered to propons, it is achieved thereby that the function of four-wheel drive.
