Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, and specifically relates to an installation device for an automobile support shaft with an anti-dropping structure. Background Technique

[0002] The engine is the most important part of an automobile. Generally, engine mounts are installed on the engine. The engine mounts can prevent the vibration during engine operation from being directly transmitted to the vehicle frame, thereby improving the riding comfort and the quietness inside the vehicle.

[0003] Currently, the invention patent with the publication number of CN217713499U discloses an automobile rubber engine mount with good damping effect. When installing the device, the threaded rod is tightened. Through the cooperation of the control mechanism, the limiting mechanism and the limiting groove, the limiting block can extend into the limiting groove, and then the turntable can be limited, preventing the threaded rod from loosening due to long-term vibration when the engine starts, which may affect the connection of the device. This is to solve the problem that when some automobile rubber engine mounts are installed, the device is connected to the engine through bolts. However, when the engine starts, due to the long-term vibration of the engine, the bolts may loosen, which will affect the connection of the device.

[0004] The existing engine mounts reduce the vibration of the engine transmitted to the mounts through damping. By improving the damping effect, the bolts of the mounts can be prevented from loosening. However, under the long-term vibration effect, the damping structure will cause fatigue, and the damping effect will gradually become worse, still resulting in the risk of the mounts falling off during use. To solve the above problems, an installation device for an automobile support shaft with an anti-dropping structure is proposed in this application. Content of the Utility Model
