The utility model can increase the radial rigidity adjusting range and improve the durability; the axial rigidity adjusting range can be enlarged, and the comfort of the vehicle is improved; the problem of rigidity adjustment and durability balanced with each other is solved.
Description
Technical Field
The utility model belongs to vehicle chassis, concretely relates to car rear axle bush structure.
Background
The existing rear axle bush mainly takes the form of an original inner framework 10, an original rubber elastic part 20 and an original outer framework 30, and is shown in figure 1. The rear axle bush of this structure has the following disadvantages: the rigidity and the durability in all directions are adjusted by the original rubber elastic part 20, and the adjustment range of the dynamic and static rigidity ratio is limited, so that the optimal state cannot be reached; durability is limited, resulting in an imbalance between vehicle performance and durability. Therefore, further improvements are needed.
CN 210478325U discloses "a rear axle bushing and twist beam suspension", the rear axle bushing includes: a bushing outer tube; the bushing inner pipe is coaxially inserted into the bushing outer pipe, an annular bulge surrounding the bushing inner pipe along the circumferential direction of the bushing inner pipe is arranged on the outer wall of the bushing inner pipe, the outer contour of the radial section of the annular bulge is provided with at least two positions with different distances from the inner wall of the bushing outer pipe, and the rubber connecting piece is connected between the bushing inner pipe and the bushing outer pipe. The rear axle sleeve has good rigidity, and meanwhile, the rear axle sleeve has good capability of adjusting movement clearance, and the comfort of a vehicle is improved. The technical solution disclosed in this patent document is a useful attempt in the field of the technology.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an automobile rear axle bushing sleeve structure which can increase the radial rigidity adjusting range and improve the durability; the axial rigidity adjusting range can be enlarged, and the comfort of the vehicle is improved; the problem of rigidity adjustment and durability balanced with each other is solved.
A car rear axle bush structure, include endotheca skeleton, overcoat skeleton and establish the rubber elastic component between endotheca skeleton and overcoat skeleton, characterized by:
the inner rubber pad is annular and is arranged between the upper parts of the inner sleeve framework and the outer sleeve framework and is abutted against the upper end of the rubber elastic piece;
the middle part of one outer rubber pad is provided with a via hole which is arranged at the lower end parts of the inner sleeve framework and the outer sleeve framework and is close to the lower end of the rubber elastic piece.
Further, the inner sleeve framework and the outer sleeve framework are coaxially arranged; the rubber elastic piece is vulcanized between the inner sleeve framework and the outer sleeve framework.
Furthermore, the inner sleeve framework is made of steel, steel and nylon or aluminum alloy.
Furthermore, the material of the outer sleeve framework is steel or aluminum alloy.
The utility model discloses compare in traditional rear axle bush have following beneficial effect:
because the inner rubber pad and the outer rubber pad are added, the rigidity of each direction can be changed by adding the inner rubber pad, so that the rigidity range of the whole bushing is wider, the durability can be improved, and the problem that the rigidity adjustment and the durability of the traditional bushing are balanced is solved; the outer rubber pad can improve the axial rigidity, so that the axial rigidity adjusting range of the whole bushing is larger, the operation stability of the whole vehicle can reach the optimal state, and the impact abnormal sound risk of the bushing and the rear axle bushing mounting bracket is avoided.
The utility model has the advantages of good durability, wide performance debugging range, shortened development cycle and the like.
Drawings
Fig. 1 is a schematic structural view of a conventional rear axle bush.
FIG. 2 is a schematic structural view of the present invention;
fig. 3 is an exploded view of the present invention.
In the figure:
10-original inner framework, 20-original rubber elastic piece and 30-original outer framework;
1-inner sleeve framework, 2-rubber elastic member, 3-outer sleeve framework, 4-inner rubber pad and 5-outer rubber pad.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 2 and 3, the automobile rear axle bush structure includes an inner sleeve frame 1, an outer sleeve frame 3 and a rubber elastic member 2 arranged between the inner sleeve frame and the outer sleeve frame, and is characterized in that:
an inner rubber pad 4 is annular and arranged between the upper parts of the inner sleeve framework 1 and the outer sleeve framework 3 and is abutted against the upper end of the rubber elastic piece 2; the performance parameters of the inner rubber pad can be improved by adjusting the hardness and the structure of the inner rubber pad, and the inner rubber pad is matched with the rubber elastic piece, so that the rigidity and the durability of the whole bushing are in the optimal state.
The middle part of an outer rubber pad 5 is provided with a via hole which is arranged at the lower end parts of the inner sleeve framework 1 and the outer sleeve framework 3 and is abutted against the lower end of the rubber elastic piece 2. The outer rubber pad adjusts the hardness and structural parameters according to the opening size and the axial rigidity requirement of the rear shaft bushing mounting bracket, supplements the axial rigidity which cannot be provided by the rubber elastic piece, can improve the operation stability of the whole vehicle, and can avoid the impact abnormal sound risk generated by the bushing and the rear shaft bushing mounting bracket.
The inner sleeve framework 1 and the outer sleeve framework 3 are coaxially arranged; the rubber elastic member 2 is vulcanized between the inner sleeve framework 1 and the outer sleeve framework 3. The rubber elastic piece is used for connecting the inner and outer sleeve frameworks, has a vibration damping effect and provides main rigidity and durability for the bushing.
The inner sleeve framework 1 is made of steel, steel and nylon or aluminum alloy.
The outer sleeve framework 3 is made of steel or aluminum alloy.
The utility model discloses an increase the inner rubber pad for each direction rigidity control range is bigger, improves durability simultaneously. The outer rubber pad is added, so that the axial rigidity adjusting range is larger.
