Further, the butt-inserting buffer 4 needs to be connected through a plug-in type, the buffer portion 44 is used for surrounding the connecting frame 1, referring to fig. 4, when the convex plate 41 is inserted into the side surface of the center frame 2, the convex portion of the convex plate 41 enters the cavity through the open end of the side surface of the center frame 2, the buffer portion 44 is fixed on the convex surface of the convex plate 41, so that the buffer portion 44 enters the center frame 2, the buffer portion 44 surrounds the top surface, the bottom surface and the side surface of the connecting frame 1, and when the end portions of the two buffer portions 44 are in butt joint, the two buffer portions 44 form a shape of a "mouth" to surround the periphery of the connecting frame 1. In the process, the center frame 2 and the connecting frame 1 do not have any disassembling action with the vehicle body, so that the service life of the screw holes and the stability of fixation are ensured.

Therefore, the anti-displacement imitation grooves 23 are formed in the top surface and the bottom surface of the center frame 2, the convex buffering strips 43 and the buffering parts 44 are integrally formed, the buffering parts 44 are inserted into the anti-displacement imitation grooves 23, and displacement of the buffering parts 44 is avoided.

Further, the side surface of the convex plate 41 is fixedly connected with a plurality of reinforcing limiting core rods 42, two reinforcing limiting core rods 42 penetrate through the convex buffering strips 43 in pairs, the distance between two reinforcing limiting core rods 42 in the same group is larger than the width of the closing end of the anti-displacement imitation groove 23, the convex buffering strips 43 are easily inserted into the anti-displacement imitation groove 23 due to large friction force of rubber, and the convex buffering strips 43 are easily inserted into the anti-displacement imitation groove 23 mainly due to the influence of deformation, so that the insertion is incomplete due to deformation, and a large gap is generated between the two buffering parts 44.

In order to avoid the impact of the gap on the cushioning, a central groove 11 is provided in the middle of the connecting frame 1, the central groove 11 not only provides space for the subsequent locking, but also allows the presence of the central groove 11 so that the gap does not come into contact with the connecting frame 1. Therefore, the reinforcing limiting core rods 42 are arranged at the convex buffer strips 43, the two reinforcing limiting core rods 42 are located at the wide sides of the convex buffer strips 43, and when the reinforcing limiting core rods 42 are inserted into the anti-displacement imitation grooves 23 along with the convex buffer strips 43, the reinforcing limiting core rods 42 are in limiting connection with the closing-in parts of the anti-displacement imitation grooves 23.

Further, it is necessary to avoid the situation that the connection frame 1 is not affected by the inclination of other bracket assemblies due to the supporting force of the -shaped buffer portion 44 during the replacement, and it is necessary to pre-support the connection frame 1 and the center frame 2 before the insertion buffer 4 is separated. At this time, the central groove 11 is formed in the surface of the connection frame 1, the central temporary lock 3 is rotated in the middle of the central frame 2, the central supporting rod 31 is smaller than the width of the central groove 11 due to the diameter, meanwhile, the central groove 11 is rectangular, and the central supporting rod 31 and the inner side surface of the central groove 11 have allowance, so that the central supporting rod 31 does not interfere with the movement of the connection frame 1 when the connection frame 1 and the central frame 2 relatively move. On the basis of the above, the width of the locking plate 36 is smaller than the diameter of the central support bar 31, and in the non-maintenance stage, the locking plate 36 is rotated to be parallel to the long side of the central groove 11, and at this time, the locking plate 36 does not have an interference effect on the displacement of the central groove 11. At the time of replacement, the center support bar 31 is moved by the rotation control part 32 to rotate the lock plate 36 to the inside of the temporary lock groove 12, and at this time, the lock plate 36 plays a role of supporting the temporary lock groove 12 longitudinally, and in this state, the positional relationship between the connection frame 1 and the center frame 2 tends to be standard.

Further, after the convex plate 41 is detached from the side wall of the center frame 2, the convex plate 41 is pulled out outwardly along the side frames 22, and the reinforcing and limiting core rod 42 is separated from the center groove 11. The supporting effect of the locking plate 36 and the temporary locking groove 12 on the central groove 11 is achieved, the service life of other suspension type brackets is prevented from being reduced due to the fact that the local stress of an engine is avoided, the brand-new opposite-plug buffer 4 is replaced, after the buffer is inserted and connected in the mode, the rotation control part 32 is controlled through a tool, the central supporting rod 31 is enabled to rotate and separate from the temporary locking groove 12, and the -shaped buffer part 44 supports the connecting frame 1. On the basis of the above, the convenience of installation has been improved, but the convex buffer strip 43 and the buffer part 44 are integrally formed, and a smooth layer is attached to the contact surface between the buffer part 44 and the connecting frame 1, at this time, the buffer part 44 is more conveniently inserted into the center frame 2 to surround the connecting frame 1.

Example 4

When the bracket assembly is not provided with the engine separation function, the rotation control portion 32 is always located inside the center frame 2. The rotation control part 32 is rotatably connected with the center frame 2, and meanwhile, the rotation control part 32 is positioned at the center of the center frame 2, the internal cavity of the whole center frame 2 is divided to form two small cavities, so that the strength is supplemented, and the rotation control part 32 is easily caused to rotate when the engine vibrates, so that the guide inclined block 33, the inserting pin 34 and the spring 35 are arranged under the condition that the rotation control part 32 and the center frame 2 have rotation damping.
