Embodiment

Below in conjunction with accompanying drawing the utility model is described further:

As shown in the figure, the 1st, oil feed pump, the 2nd, dump pump, the 3rd, main drive shaft, the 4th, gerotor type clutch coupling, the 5th, driven axle, the 6th, little portable plate, the 7th, steel ball, the 8th, clamped-in style cylinder, the 9th, fixed head, the 10th, tension formula cylinder, the 11st, big portable plate, the 12nd, bolt shaft, the 13rd, control knob plate, the 14th, clutch foot plate, the 15th, fuel tank, the 16th, oil groove.

It mainly by support, power and driving member, oil return feeding system, tried wheel box clamping and slew gear, electric oil gas control operation system etc. and formed.(see figure 2) support front end has oil groove, and the oil that will come across after the wheel box off-test enters oil groove; The support rear end is equipped with motor; Fuel tank is equipped with in the support side, and oil feed pump 1 is housed on the fuel tank, and oil feed pump injects wheel box by the pipeline oil that will come across, dump pump 2 also is housed on the fuel tank, it sucks back fuel tank by pipeline with the oil that comes across in the oil groove, (in the oil groove and in the fuel tank filter screen being housed all, with the cleaning oil that comes across).The main body of testing table is equipped with at the middle part on the support, and cast iron tandem docking formula casing is equipped with the driving force member of testing table in the casing, and the casing front end face is equipped with clamping and the revolving member that is tried wheel box.Main drive shaft 3 is equipped with at testing table casing rear portion, and the power of motor is imported testing table thus, is forward driven axle 5, its rear portion axle journal inserts in the bearing of main drive shaft 3 front ends, the front end of driven axle 5 is equipped with spline housing, and one of tested wheel box is inserted this spline housing, forms transmission of power.The bearing of main drive shaft 3 and driven axle 5 usefulness testing table housings, bearing seat support, and in the connection place of main drive shaft and driven axle gerotor type clutch coupling 4 are housed, and step clutch pedal 14, realize the connection and the cut-out of power, and the gearbox shifting test easily like this.Front end at the testing table casing is equipped with fixed head 9, there is little portable plate 6 the inside (the right) at it, there is big portable plate 11 outside (left side), both sides at fixed head 9 have groove, and big or small portable plate corresponding section also has groove, and steel ball 7 is housed in the groove, the shaft shoulder is made to both sides in the centre of fixed head 9, the center pit of size portable plate is enclosed within on the shaft shoulder of fixed head, and the two is for movingly, and big or small portable plate can rotate around the shaft shoulder.Fixed head and big or small portable plate three connect with bolt shaft 12.The hole of little portable plate bolt is a threaded hole, and the threaded hole of big portable plate is a unthreaded hole, is arc hole, garden and fixed head leaves, accompanies steel ball between such three blocks of plates, uses Bolt Connection again, and big or small portable plate relative fixed plate simultaneously rotates, as thrust bearing.Therefore the segment angle in the arc hole, garden of fixed head is 85 °, and the rotational angle of big or small portable plate is to be equipped with 2 on 0～85 °, fixed head to clamp cylinders 8, and it can strain big or small portable plate by claw, and big or small portable plate is fixed simultaneously, can not rotate by the relative fixed plate.2 tension formula cylinder 10 (III, IV) are housed on the big portable plate 11, wheel box clutch housing seam ring (not marking on the figure) also is housed, locate with this when wheel box is adorned on testing table, the claw of cylinder is pushed down wheel box clutch housing outer rim is fixed on the big portable plate wheel box.
