Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and more specifically to an engine mount. Background Technology

[0002] During vehicle operation, the engine vibrates due to its own operation, and road bumps also cause engine vibration. Excessive vibration can damage vehicle components and affect the comfort of passengers. To reduce engine vibration, engine mounts are often used at the connection between the engine and the chassis system. These mounts support the engine, reduce the impact of engine vibration on the entire vehicle, limit the amount of engine vibration, and also have a certain limiting function, ensuring that the engine's displacement within the vehicle is within an acceptable range and does not collide with other components.

[0003] Utility model patent CN218858137U discloses an automotive engine mount, in which the screw 102 of the spindle 1 is fixedly connected to the engine bracket during assembly. The first bracket 802 and the second bracket 803 on the outer frame 3 are fixedly connected to the frame bracket. The rubber anti-collision block 7 abuts against the outer side wall of the engine. In this prior art engine mount, the first and second brackets are integrally formed with the outer frame, and the connection and support of the frame rely entirely on the first and second brackets, making the structure unreliable. Furthermore, since both the first and second brackets are made of metal, the vibration damping effect on the frame is also poor. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an engine mount with good reliability and excellent vibration reduction effect on the vehicle frame.

[0005] The technical solution of this utility model is to provide an engine mount with the following structure, including a mounting base and a top cover. The mounting base is provided with a rubber base, and the rubber base is vulcanized and fixed to the mounting base. The top cover is fixedly connected to the rubber base, and the top cover is provided with a connecting bracket, and the connecting bracket is provided with a vehicle frame connecting hole. The rubber base is provided with a metal inner core, and the top cover is fitted over the metal inner core.

[0006] With the above structure, the engine mount of this utility model has the following advantages compared with the prior art:

[0007] The engine mount of this utility model includes a fixed seat and a top cover. The fixed seat is provided with a rubber base, and the top cover is fixedly connected to the rubber base. The connecting bracket is provided with a frame connecting hole. During assembly, the connecting bracket is connected to the frame. Since the top cover is fixedly connected to the rubber base, the rubber base and the top cover have a buffering effect, which makes the buffering effect of the connecting bracket better. Therefore, the engine mount structure has good reliability and a very good vibration reduction effect on the frame.

[0008] As an improvement, the upper cover has a receiving cavity and is fitted over the rubber base; the lower ends of the upper cover protrude outwards on both sides to form the connecting brackets; the side walls of the rubber base have support portions that match the connecting brackets on both sides, and the connecting brackets on both sides are fixedly connected to the support portions on both sides in a one-to-one correspondence. With this structure, the connecting brackets on both sides are fixedly connected to the support portions on both sides in a one-to-one correspondence, and the support portions provide support and shock absorption for the connecting brackets, making the suspended structure more reliable and the shock absorption effect better.

[0009] As an improvement, the connecting bracket and the supporting part are fixed together by riveting. This structure is simple, provides good fixing, and has high structural reliability.

[0010] As an improvement, the cavity of the accommodating chamber is provided with a first through hole, and the end of the metal inner core passes through the first through hole and protrudes outside the first through hole; a connecting screw is provided on the end face of the end of the metal inner core. With this structure, the structure is simple and reliable.

[0011] As an improvement, the metal core is a hollow structure, and an end cap is detachably connected to the end of the metal core. The end cap is sealed to the end face of the metal core. A second through hole is provided in the middle of the end cap, and a connecting screw is located inside the metal core, with its end passing through the second through hole and protruding outside the end cap. This structure is simple and easy to assemble.

[0012] As an improvement, a positioning protrusion is provided on the outer surface of the end cap. With this structure, the positioning protrusion has a positioning function, which can improve the assembly accuracy.

[0013] As an improvement, a rubber bumper is fixedly connected to the upper surface of the cover. The rubber bumper has a third through hole in its middle and is fitted onto the outer end of the metal inner core. With this structure, the rubber bumper can act as a buffer, improving the vibration reduction effect. Attached Figure Description
