Examples

Referring to fig. 1-4, a to pressure formula cantilever beam assembly, includes main part pole 1, mounting disc 9, screw thread section 11 and support column 15, and the middle part cover of main part pole 1 is equipped with metal casing 12, and support column 15 is installed on the right side of main part pole 1, and is fixed with mounting disc 9 through lock nut 10 at the right-hand member head of support column 15, is connected with spring 3 between mounting disc 9 and the metal casing 12:

the left end and the right end of the mounting plate 9 are both provided with gaskets 7 made of metal materials, the protective seat 8 is positioned between the two gaskets 7, the protective seat 8 is made of polyurethane materials with certain elasticity, and therefore has certain buffering characteristics, the right side of the assembly obviously has better buffering and vibration damping characteristics when the assembly is actually used, the protective seat is sleeved on a right thin column section of the supporting column 15 and limited on the thin section of the supporting column 15 through a locking nut 10, the supporting column 15 is also sleeved with a buffer block 6, the buffer block 6 is positioned on the left side of the protective seat 8, just limited on the right side, the buffer block 6 is close to the gasket 7 on the left side, when the buffer block 6 moves rightwards, the buffer block 6 just extrudes on the gasket 7 on the left side, because the gasket 7 on the left side is attached to the protective seat 8 on the right side, the buffer block 6 which performs buffering action rightwards can be formed by the protective seat 8 with buffering characteristics on the right side, the right side of the assembly mechanism is reflected to have very good buffer property;

as shown in fig. 1 and 2, a connecting ring 14 is welded at the end of a supporting column 15, a rubber ring 13 is embedded at the left end of the connecting ring 14, and the supporting column 15 is fixed at the right end of the main body rod 1 by a screw through the rubber ring 13, so that it can be seen that the shaft rod member adopted in the assembly mechanism is split, the rod member mechanism is composed of the main body rod 1 at the left side and the supporting column 15 at the right side, and the two rod members are connected through the rubber ring 13, because the rubber ring 13 has certain strength and certain buffering property, the shaft rod member of the assembly has certain buffering property on the premise of ensuring that the strength is not affected, and the assembly is further embodied to have good damping and buffering properties when actually mounted on an automobile wheel frame mechanism;

as shown in fig. 1 and 2, the threaded section 11 is disposed in the middle of the main body rod 1, and the push nut 17 is engaged with the threaded section 11, the push nut 17 is located right on the left side of the metal shell 12, the push nut 17 constitutes a rotary push mechanism located on the left side of the metal shell 12, when the push nut 17 rotates, the push nut is pressed close to the metal shell 12 to move the metal shell 12 inward, so that the spring 3, which may lose its original elasticity after being used for a period of time, is pressed against the metal shell 12 again due to the pressing of the metal shell 12, and has a certain buffering property at the same time, and the spring 3 is replaced by a new spring 3 after the automobile arrives at a repair shop, thereby showing the characteristic of flexible adjustment of the present assembly mechanism.

Specifically, as shown in fig. 1 and 3, the buffer block 6 is a gourd-shaped polyurethane sleeve, a ring of annular groove 16 is formed in the left side of the buffer block 6, and a backing ring 5 is embedded in the annular groove 16.

Specifically, backing ring 5's outside veneer has dust cover 4, the left end suit of dust cover 4 is on the right-hand member head of main part pole 1, dust cover 4 forms dustproof effect to buffer block 6, dust cover 4 adopts bellows style simultaneously, and because the left end adopts the mode cover of suit on the right-hand member head of main part pole 1, consequently, metal casing 12 when the buffering action of right, also can extrude on dust cover 4, make dust cover 4 also can move to the right, and after metal casing 12 resets left once more, dust cover 4 also can reset left because of it is elasticity bellows reason, and it is more reasonable structure.

Specifically, as shown in fig. 2, since the diameter of the push nut 17 is larger than the right end of the metal shell 12, the metal shell 12 is slidably fitted to the main rod 1, and therefore, when the push nut 17 is rotated to move rightward, the metal shell 12 is pressed rightward.

Specifically, the inner wall of metal casing 12 is provided with round spring pad 2, and the left side of spring 3 supports on spring pad 2, therefore the order just has the spring 3 of buffering application characteristic originally, and the left side has embodied the buffer characteristic again after receiving the spacing support of spring pad 2 to when making this mechanism cooperation use on the car, the buffer structure of buffer gear than current is perfect and reasonable more.

Specifically, the right side welding of spring 3 has the welding ring 18, and weld ring 18 and spacing in the ring channel of seting up on the outer wall of buffer block 6 again, transmit spring 3's slow pressure characteristic on buffer block 6, because buffer block 6 moves when moving along with spring 3, can press on left packing ring 7, consequently, further embodied buffer characteristic, buffer characteristic through buffer block 6 formula right on support column 15, consequently, help spring 3 to reach better buffering effect.

The working principle is as follows:

the left end and the right end of the device are arranged on a beam hanging part or a wheel carrier part of an automobile according to the existing installation technology for use, if the automobile runs for a period of time, the spring 3 can be pressed by the metal shell 12 which is frequently and slowly pressed and then loses the original high-strength elastic tension, when a driver overhauls the automobile by himself, the nut 17 can be automatically rotated and pushed to be close to the pressing action of the metal shell 12, the metal shell 12 is forced to be pressed inwards, the spring 3 which is pressed on the inner side of the metal shell 12 is in elastic contact with the metal shell 12 again, the spring 3 still can play a certain outward expansion type elastic characteristic within a certain period of time, and the new spring 3 is replaced until the automobile arrives at a repair shop, the whole shock absorber does not need to be replaced, only the spring fittings need to be replaced, the cost is saved, and the characteristic of flexible adjustment of the assembly mechanism is reflected.
