Referring to fig. 1 to 3, a first embodiment of the present invention provides a bushing, which includes an inner frame 2, an outer frame 1 and a buffer assembly 3.

Specifically, the inner frame 2 with the outer frame 1 is the loop configuration, 1 cover of outer frame is established on the inner frame 2, buffering subassembly 3 set up in outer frame 1 with between the inner frame 2, buffering subassembly 3 includes that the first piece 31, the second of colliding hits piece 32 and connecting block 33, the first piece 31 that hits set up in the internal surface of outer frame 1, the second hit the piece 32 set up in the surface of inner frame 2, connecting block 33 with inner frame 2 with outer frame 1 fixed connection, and with the second hits piece 32 integrated into one piece, the first piece 31 that hits is the indent structure, the second hits piece 32 and is the evagination structure, the first piece 31 that hits with the second hits piece 32 and sets up relatively, and reserves the clearance between the two.

In this embodiment, the buffer component 3 is made of rubber, but in other embodiments, it may be made of other flexible materials.

Referring to fig. 4, the bushing of the present embodiment is installed in the rod sleeve of the push rod 5, and then the bolt penetrates through the bushing to connect with the bracket 4. During the running of the automobile, the push rod 5 or the bracket 4 can generate vibration mutually and transmit the vibration to the other side, and the vibration energy can be reduced by the lining.

The utility model has the advantages that the buffering component 3 is divided into a first collision block 31 and a second collision block 32, and the first collision block 31 and the second collision block 32 can collide with each other in the driving process of the automobile, and can directly collide with the outer framework 1, so that the cracking probability of the buffering component 3 is lower; because the first collision block 31 and the second collision block 32 are separated from each other, when the first collision block and the second collision block collide with each other, one of the two collision blocks cannot be twisted due to the twisting of the other collision block, and the probability of cracking of the first collision block and the second collision block is further reduced.

Preferably, the surface of the second striking block 32 is uniformly provided with ribs, so that when the first striking block 31 and the second striking block 32 collide with each other, the ribs are preferentially rubbed, and the friction loss of the body of the first striking block 31 is reduced.

In addition, the first collision block 31 is of an arc-shaped concave structure, and the outermost end of the second collision block 32 is of a folded edge structure.

It should be noted that the outermost end of the second bump block 32 can be understood as a tip, which is not matched with the surface of the first bump block 31, and when a collision occurs, the outermost end of the second bump block 32 will preferentially contact with the first bump block 31, and then when the second bump block is worn, the wear will be slowly started from the smallest tip, so that the wear time of the second bump block 32 is prolonged, and the service life is prolonged.

In addition, the inner frame 2 is a cylindrical structure, and compared with a traditional flat structure, the vibration energy transmitted in all directions of the inner frame 2 is almost consistent, so that the buffer assembly 3 is prevented from being too fast lost due to single-direction shaking and overexcitation.

Preferably, the surface of inner frame 2 is equipped with boss 21 around itself, inner frame 2 passes through boss 21 with connecting block 33, second hit the piece and connect 32, boss 21 is followed the length of the axis of inner frame 2 is less than 2 lengths of inner frame.

It can be understood that the body of the inner frame 2 is longer than the boss 21, so that the protrusion along the axial direction can be formed, and the buffer component 3 is arranged on the boss 21 because the lining is arranged on the support 4, the support 4 can be preferentially rubbed with the inner frame 2 and can not be rubbed with the buffer component 3, so that the loss of the buffer component 3 caused by the friction of the support 4 is avoided.

In addition, the two sides of the first collision block 31 are provided with the buffer grooves 311, and the buffer grooves 311 can bend when the two sides of the first collision block 31 are collided to form avoidance, so that the direct collision force is reduced, and the service life of the first collision block 31 is prolonged.

In addition, the area of the connecting surface of the connecting block 33 and the inner frame 1 is larger than that of the connecting surface of the outer frame 2. It can be understood that the connecting block 33 is a structure gradually thickened from the inner frame 1 to the outer frame 2, and the strength of the connecting block 33 is increased, so that the connecting block is not easily torn.

A second embodiment of the present invention provides a rear longitudinal putter assembly, which comprises at least a bushing in the first embodiment.

In the description herein, references to the description of the term "one embodiment," "some embodiments," "an example," "a specific example," or "some examples," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention.
