Description of reference numerals: 1, propelling rod; 2, the axle collar; 3, bearing pin; 3a, central part; 3b, 3c, first, second end; 4, jump ring groove; 5, first jump ring; 6, second jump ring; 7, Rubber Parts.

The specific embodiment

As shown in Figure 1, there is shown the cutaway view of the mounting structure of the utility model propelling rod bearing pin.Wherein, the mounting structure of propelling rod bearing pin of the present utility model comprises the axle collar 2 that is positioned at propelling rod 1 termination, is set with bearing pin 3 in the axle collar 2.

Bearing pin 3 has central part 3a spherical in shape that is sleeved in the axle collar 2 and the both ends of stretching out the axle collar 2 respectively to two ends, and promptly first, second end 3b, 3c are respectively equipped with hinge hole on both ends 3b, the 3c, so that hinged with vehicle body and jackshaft or back axle respectively; Ball-shaped central part 3a outer wrapping or be set with Rubber Parts 7, it is cylindrical that the outside of Rubber Parts 7 is ladder, and Rubber Parts 7 combines with the outer spherical surface of spherical central part 3a by its spherical inner chamber and is connected as a single entity with it.

The central part 3a of bearing pin shown in Fig. 13 is spherical, and central part 3a can also be cylindrical (not shown).

Rubber Parts 7 is sleeved in the axle collar 2, has first cylinder that is positioned at the middle part and second cylinder at two ends, and wherein the outside face of first cylinder combines with the inner cylinder face of the axle collar, second cylinder at Rubber Parts 7 two ends outward the garden diameter less than the outside diameter of first cylinder.

As shown in Figure 1, one end inwall of the axle collar 2 is provided with a circle jump ring groove 4, first jump ring 5 and second jump ring 6 are installed in the jump ring groove 4, first and second jump ring 5,6 all has opening, and when two jump rings 5,6 stack together when being installed in the jump ring groove 4 jointly, the opening of the opening of first jump ring 5 and second jump ring 6 staggers mutually.Two jump rings 5,6 are installed in the jump ring groove 4, ring diameter is less than the interior ring diameter of the axle collar 2 in it, make the part of two jump rings 5,6 stretch out jump ring groove 4, second jump ring, 6 its parts of stretching out jump ring groove 4 that are stacked in the below so just are resisted against on the end face of first cylinder of Rubber Parts 7, so that bearing pin 3 is fixed in the axle collar 2.In other words, the outer portion of first, second jump ring 5,6 is placed in the jump ring groove 4, and its internal ring portion stretches out the jump ring groove, and wherein an end of second jump ring, 6 internal ring portions is resisted against on the end face of Rubber Parts 7 first cylinders, by Rubber Parts 7 bearing pin 3 is fixed in the axle collar 2 thus.

As shown in Figure 2, there is shown the stacked mode scheme drawing of two jump rings, wherein the opening part of first jump ring 5 and second jump ring 6 staggers mutually.For the clear opening of first jump ring 5 and second jump ring 6 that shows staggers mutually, there is shown two jump rings and be separated from each other, in fact two jump rings the 5, the 6th stack together up and down.As shown in Figure 1, 2, first jump ring 5 is stacked in the top of second jump ring 6, and the opening part of first jump ring 5 is positioned at the right side, and the opening part of second jump ring 6 is positioned at left side (shown in Figure 2), like this, can be so that two jump rings produce the locking effect each other, thus constitute the jump ring lock ring of a no stressed thin spot.

When propelling rod 1 bears powerful torsion and push-pull effort is done the time spent, bearing pin 3 in the axle collar 2, be subjected to brute force and about the extruding, because the jump ring lock ring that two jump rings 5,6 constitute does not have stressed thin spot, even therefore under the effect of brute force, the jump ring lock ring that two jump rings 5,6 constitute can not deviate from jump ring groove 4 yet, so just can avoid the inefficacy of propelling rod 1.

Although above the utility model has been done detailed description; but the utility model is not limited thereto; those skilled in the art can make amendment according to principle of the present utility model; therefore, all various modifications of carrying out according to principle of the present utility model all should be understood to fall into protection domain of the present utility model.
