Summary of the Utility Model

[0003] The purpose of the utility model is to provide a rubber shock-absorbing bushing with strong torsion resistance.

[0004] The purpose of the utility model is realized as follows: a torsion-resistant rubber shock-absorbing bushing, including a bushing body, a rubber shock-absorbing part is arranged on the bushing body, a connection hole is opened in the bushing body, a spherical inner tube is connected to the connection hole, a spherical connection part is arranged in the middle of the spherical inner tube, and a middle ball seat is connected to the spherical connection part.

[0005] Preferably, a plurality of grooves are evenly opened on the side of the middle ball seat, the bottom of the groove is flush with the bottom of the middle ball seat, and the top height of the groove is higher than the center height of the middle ball seat.

[0006] Preferably, connection protrusions are arranged on both sides of the spherical inner tube, a cage is connected to the connection protrusions, and a dust cover is arranged in the cage.

[0007] Preferably, a connection groove is opened in the cage, a dust-proof connection part is arranged on the dust cover, one end of the dust-proof connection part abuts against the connection groove, a dust-proof part is arranged at the other end of the dust-proof connection part, and one end of the spherical inner tube is in the dust-proof part.

[0008] 1. Preferably, a rubber buffer part is arranged on the rubber shock-absorbing part, placing grooves are opened on both sides of the connection hole in the bushing body, the cage is in the placing groove, and a riveting part is arranged on one side of the placing groove, and the upper end of the cage is flush with the riveting part.

[0009] In addition, the utility model also provides a vehicle, and the vehicle includes the above-mentioned torsion-resistant rubber shock-absorbing bushing.

[0010] The prominent and beneficial technical effects of the utility model compared with the prior art are:

[0011] 1. When the spherical inner tube is connected and installed in the bushing body through the middle ball seat, since the spherical connecting part of the spherical inner tube is spherical, the spherical inner tube can rotate within the bushing body. Different from the conventional bushing body and straight tube inner tube on the market that are forcibly twisted and cannot rotate, the spherical connecting part in a spherical shape can increase the torsional resistance of the structure of the present utility model. Then, shock absorption is carried out through the rubber shock absorption part on the bushing body, improving the operating experience of the operator and increasing the service life.
