Abstract
The utility model discloses a noise-proof rubber bushing for a hanger bracket of an automotive chassis. The bushing is a hollow cylinder which is integrally vulcanized; a flange greater than the other parts is arranged at one end of the bushing; spherical bumps are arranged at the annular end face at the flange end of the bushing, and the spherical bumps are distributed on an annular lug boss which is smaller than the spherical bumps in diameter at the annular end face. According to the noise-proof rubber bushing for the hanger bracket of the automotive chassis, the annular lug boss and the spherical bumps are added to the contact end face of the rubber bushing and a metal element to reduce the contact area, so that the noise can be prevented.
Description
Technical field
The utility model relates to the automobile chassis suspension driving system, is specifically related to the anti-abnormal sound lining that a kind of automobile chassis suspension is used.
Background technique
Along with the continuous expansion of user vehicle, the user group requires more and more higher to the perceptibilities such as abnormal sound of car, and lining is as part common in the suspension system of chassis, and it is preventing that user's requirement is more and more higher aspect the abnormal sound.The main structure that lining adopts in the suspension system of automobile at present is natural rubber or increases the additives such as ageing-resistant, to realize the special performance in some aspect of lining, present existing bush structure mainly focuses on to improve and reverses Endurance life, prevent lining cracking etc., but because at the weather high humidity or in rainy day, the rubber-based products friction factor increases, the rubber-like lining rotates the relative frictional force that produces with metalwork and becomes large, make in the automobile use and produce " quack " sound because of this frictional force, produce the friction abnormal sound, cause the noise of car load to increase.
The model utility content
The technical problems to be solved in the utility model provides the anti-abnormal sound lining that a kind of automobile chassis suspension is used, and reduces lining and metal caul and relatively rotates friction and the abnormal sound of generation.
For solving the problems of the technologies described above, the utility model proposes following technological scheme:
The anti-abnormal sound rubber bushing that a kind of automobile chassis suspension is used, described lining are the hollow circular cylinders of a whole sulfuration,, an end of lining has the flange greater than remaining part, it is characterized in that: be provided with hemisphere jut on the ring end face of the flange end of described lining.
Described hemisphere jut is distributed on the described ring end face than on the little round ring boss of its diameter.Described hemisphere jut presents the evenly distribution of two circles along the center of circle of round ring boss.
The utility model is by contacting end face increase round ring boss and hemisphere jut structure with metalwork at rubber bushing, reducing area of contact, thereby can prevent abnormal sound.
Description of drawings
The structural representation of the former plain bushing of Fig. 1;
The structural representation of Fig. 2 anti-abnormal sound lining of the present utility model;
The assembling section of Fig. 3 anti-abnormal sound lining of the present utility model.
Embodiment
Below in conjunction with accompanying drawing formation of the present utility model is further specified.
Fig. 1 is former common bush structure, is the hollow circular cylinder that the sulfuration of unitary mould injecting glue forms, and the flange end 1-1 of lining is leveling face, is that face contacts with metal caul, and area of contact is large.And lining is the General Purpose Rubber material, unlubricated agent prescription, and the friction factor of gasket end 1-1 and metal caul is large, and when meeting rainy day during at motor racing, lining 1 has with metal caul 2 and relatively rotates friction and then produce abnormal sound.
Fig. 2 is the abnormal sound lining that prevents of the present utility model, it farthest reduces the entire area size of the flange end 1-1 of lining 1, namely form a round ring boss 1-3 less than its diameter thereon, be again two circles in the center of circle along round ring boss 1-3 and be evenly distributed with a lot of hemisphere jut 1-2, thereby reduce the real contact area of the metal backing 2 of flange end 1-1 and Locking bushing, under equal coupling mechanism force effect, lining 1 obviously descends with the frictional force of metal caul 2.
In addition, for effectively reducing lining 1 and metal caul 2 mutual friction factor in the automobile use, can in the rubber compounding of lining 1, increase the acetic acid amide additive, because acetic acid acid amides and rubber molecule do not merge, in lining uses, it constantly oozes out from the colloid of lining 1 because intermolecular repulsive interaction makes the acetic acid amide molecule, guarantee that lining 1 surface is covered with the acetic acid amide molecule and guarantees that surface lubrication is to reduce frictional force, after lining 1 and metal caul 2 were locked, the frictional force of motion can effectively reduce mutually.
After the optimization on the said structure or on the meterial additive and adjusting, as shown in Figure 3, two lining 1 symmetries are contained in the rod member collar 4 of chassis part, and metal caul 2 is realized fastening locking with lining 1 by lock bolt 3.When humidity of the air was large or rainy, lining 1 significantly descended with the frictional force of metal caul 2 in automobile uses, and eliminates the friction abnormal sound.
Claims (3)
1. anti-abnormal sound rubber bushing that automobile chassis suspension is used, described lining are the hollow circular cylinders of a whole sulfuration, and an end of lining has the flange greater than remaining part, it is characterized in that: be provided with hemisphere jut on the ring end face of the flange end of described lining.
2. the anti-abnormal sound rubber bushing used of automobile chassis suspension according to claim 1 is characterized in that described hemisphere jut is distributed on the described ring end face than on the little round ring boss of its diameter.
3. the anti-abnormal sound rubber bushing used of automobile chassis suspension according to claim 1 and 2 is characterized in that, described hemisphere jut presents two circles along the center of circle of round ring boss and evenly distributes.
