Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose of the present invention, the following detailed description of the embodiments, structures, features and effects of the present invention will be made with reference to the accompanying drawings and examples.
As shown in fig. 1, a rear axle bracket 1 according to an embodiment of the present invention includes a bottom plate 11 and two side plates 12 and 13 disposed on two opposite sides of the bottom plate 11, wherein a through hole is respectively disposed on the two side plates 12 and 13. One of the through holes is inserted with a movable cylinder sleeve 2 which can move along the axial direction of the corresponding through hole, in the embodiment, the movable cylinder sleeve 2 is arranged on the side plate 12. The rear axle bracket 1 is a cast steel bracket. The two side plates 12, 13 and the bottom plate 11 form a U shape.
In addition, in order to prevent the movable cylinder liner 2 from falling off the side plate 12 and to enable the movable cylinder liner 2 to move in the through hole of the side plate 12 in the axial direction of the through hole, the movable cylinder liner 2 may be inserted into the through hole of the side plate 12 in an interference fit manner, and a deformation groove 21 may be provided in the wall portion of the movable cylinder liner 2, the deformation groove 21 extending in the radial direction of the movable cylinder liner and penetrating the wall portion of the movable cylinder liner 2 in the axial direction of the movable cylinder liner. Because the existence of deformation groove 21, when exerting an axial force for movable cylinder liner 2, movable cylinder liner 2 can take place elastic deformation, makes to have certain clearance between interference fit's movable cylinder liner 2 and the through-hole originally to make movable cylinder liner 2 can follow the axial displacement of through-hole in the through-hole of curb plate 12.
As shown in fig. 2 and 3, the rear axle bracket connecting structure according to an embodiment of the present invention includes a rear axle bracket 1 and a rear axle bushing 3 connected to a rear axle. Rear axle support 1 includes bottom plate 11 and locates two curb plates 12, 13 of two opposite sides of bottom plate 11, respectively is equipped with a through-hole on two curb plates 12, 13, and rear axle bush 3 locates between two curb plates, and a bolt 4 passes through-hole and rear axle bush 3 and is fixed in rear axle support 1 with rear axle bush 3. The rear axle bracket 1 is a cast steel bracket. The two side plates 12, 13 and the bottom plate 11 form a U shape.
One of the through holes has a movable cylinder liner 2 inserted therein, which is axially movable along the corresponding through hole, and in this embodiment, the movable cylinder liner 2 is provided on the side plate 12. As shown in fig. 2, when the bolt 4 does not apply a fastening force, there is an axial gap between the rear axle bushing 3 and the side plate 12 to which the rear axle bushing 3 is mounted, which may be 2-3 mm. The rear axle bush 3 and the side plate 13 to which the rear axle bush 3 is not attached are bonded to each other.
In order to prevent the movable cylinder sleeve 2 from falling off from the side plate 12 and enable the movable cylinder sleeve 2 to move in the through hole of the side plate 12 along the axial direction of the through hole, the movable cylinder sleeve 2 can be inserted into the through hole of the side plate 12 in an interference fit manner, a deformation groove 21 is formed in the wall of the movable cylinder sleeve 2, and the deformation groove 21 extends in the radial direction of the movable cylinder sleeve and penetrates through the wall of the movable cylinder sleeve 2 along the axial direction of the movable cylinder sleeve. Because the existence of deformation groove 21, when exerting an axial force for movable cylinder liner 2, movable cylinder liner 2 can take place elastic deformation, makes to have certain clearance between interference fit's movable cylinder liner 2 and the through-hole originally to make movable cylinder liner 2 can follow the axial displacement of through-hole in the through-hole of curb plate 12.
As shown in fig. 3, during the application of the fastening force to the bolt 4, the movable cylinder liner 2 moves in the axial direction of the corresponding through-hole, and gradually fills the axial gap to gradually decrease the axial gap.
In conclusion, owing to insert in the inside of one of them of two through-holes of two curb plates and be equipped with movable cylinder sleeve 2 that can follow corresponding through-hole axial displacement, can eliminate rear axle bush 3 and install the axial clearance between the curb plate of this rear axle bush 3 through movable cylinder sleeve 2, consequently the utility model provides a rear axle support and rear axle support connection structure can realize the effective connection of rear axle support and rear axle bush, have avoided being connected unstably between rear axle support and the rear axle bush because axial clearance between rear axle bush 3 and the curb plate and arouse.
The above is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiments, and although the present invention has been disclosed with the above preferred embodiments, but the present invention is not limited to the above embodiments, and any skilled person in the art can make some changes or modifications to equivalent embodiments without departing from the technical scope of the present invention, but all simple modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention still belong to the technical scope of the present invention.
