Embodiment
For further understanding innovation and creation content, the Characteristic of the invention, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As depicted in figs. 1 and 2, the test unit of a kind of final drive shaft and the interlock of auxiliary transmission shaft, comprise protective cover 1, protective cover is made up of fixed enclosure and unlatching cover body, open rolling bearing on cover body hand wheel shaft 6 is installed, hand wheel shaft is along the radially setting of protective cover, the outer end of hand wheel shaft is provided with handwheel 7, the inner of hand wheel shaft is installed with conical gear second 8, on unlatching cover body, go back rolling bearing screw mandrel 3 is installed, the axis of screw mandrel is parallel with the axis of final drive shaft and auxiliary transmission shaft, one end of screw mandrel is installed with conical gear first 5, screw mandrel is vertical with hand wheel shaft, conical gear first engages with conical gear second, shift fork 9 is installed on screw mandrel, shift fork comprises the screw 19 being connected with wire rod thread, the sliding set 21 that is sleeved on rolling bearing first one side outside be connected sliding set, the fork plate 20 of screw, fork plate is also sleeved on the guide pole parallel with screw mandrel 4, what guide pole was fixing is arranged on the support body for supporting screw mandrel.
Rolling bearing second 13 is sleeved on sliding sleeve 14, rolling bearing second is blocked by the circlip for shaft on sliding sleeve, in sliding sleeve, be provided with large spline housing 16, in large spline housing, be provided with little spline housing 15, inner side and final drive shaft 18 spline joints of large spline housing, final drive shaft inner side is provided with auxiliary transmission shaft 17, large spline housing is provided with the spline coordinating with large spline sleeve, radially be provided with through hole along sliding sleeve on sliding sleeve, in through hole, be installed with adjusting bolt 2, adjusting bolt is threaded with the threaded hole radially arranging along little spline housing.
As shown in figures 1 and 3, in large spline housing also by rolling bearing first 12 roll be provided with top 11, top being contained on large spline housing 16, top point withstands on auxiliary transmission shaft.
The operating principle of the invention is:
Rotate handwheel 7, drive hand wheel shaft 6 to rotate, the conical gear second 8 of hand wheel shaft medial end drives conical gear first 5 to rotate, and conical gear second drives screw mandrel rotation.Because the fork plate of shift fork is sleeved on guide pole 4, so the guide effect of guide pole causes shift fork not rotate, screw part and the screw mandrel of shift fork relatively rotate, so shift fork does rectilinear motion on screw mandrel.Because the sliding set of shift fork is on the outer ring that is sleeved on rolling bearing second 13 partly, and rolling bearing second is blocked by the circlip for shaft on sliding sleeve, so can drive sliding sleeve 14 slide by rolling bearing second.
Because the adjusting bolt being through on the through hole of sliding sleeve is also threaded with the threaded hole on little spline housing, so in the time that sliding sleeve slides, the slip of sliding sleeve also can drive the slip of little spline housing 15.So when shift fork is positioned at the left side of Fig. 1, when little spline housing is sleeved on auxiliary rotation axis 17, by final drive shaft → large this drive path of spline housing → adjusting bolt → little spline housing → auxiliary transmission shaft, just can make auxiliary transmission shaft rotate with same speed with final drive shaft.When shift fork is positioned at the right side of Fig. 1, when little spline housing just can not be sleeved on the outside of auxiliary transmission shaft, above-mentioned driving chain is interrupted, and the rotation of final drive shaft just can not change into the rotation of auxiliary transmission shaft.So this test unit has been realized the free break-make of little spline housing and auxiliary transmission shaft, also just realize the requirement that main and auxiliary transmission shaft links at any time.
In addition, adjusting bolt not only can realize being connected of sliding sleeve and little spline housing, can also utilize the many adjusting bolts that are arranged on sliding sleeve, by regulating screw thread being screwed into the degree of depth and adjusting the axial location of little spline housing of little spline housing upper screwed hole, thereby ensure the right alignment between little spline housing, large spline housing.
Although by reference to the accompanying drawings the preferred embodiment of the invention is described above; but the invention is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under the enlightenment of the invention; not departing from the scope situation that the invention aim and claim protect, can also make a lot of forms, within these all belong to the protection domain of the invention.
