With the effect of vibration damping, meanwhile, spacing rubber 204 can also prevent the damage to bushing for the mounting bracket 201.
Spacing rubber 204 can be connected to sleeve 205 by way of bonding or mode connects for screw it is also possible to direct compress
Between sleeve 205 and mounting bracket 201, preferably spacing rubber 204 is adhered to sleeve 205, to prevent altering of spacing rubber 204
Dynamic and easy for installation.
Preferably, spacing rubber 204 is provided with several boss near the side of suspension strut 201, and boss is along spacing rubber
204 circumferentially distributed.To improve the intensity of spacing rubber 204, meanwhile, further function as the effect relaxing shock and vibration.Convex
Platform can be sector structure or column structure, preferably sector structure, and is uniformly distributed along spacing rubber 204 circumference, with
Preferably improve the intensity of spacing rubber 204, play the effect preferably protecting bushing.
Spacing rubber 204 can also arrange other reinforcement structures, such as strengthening groove, or reinforcement.
The outer wall of sleeve 205 is connected with air filter bracket 206, and air filter bracket 206 and frame brackets 203 are along sleeve 205
Circumferential is staggeredly located.This structure facilitates the installation of air filter, and integrated level is high.
Air filter bracket 206 can be welding, riveting or mode connects for screw with the connected mode of sleeve 205, preferred weld,
Convenient processing.
Preferably air filter bracket 206 installed surface perpendicular to frame brackets 203 installed surface.This structure makes air filter install
After can preferably work, to extend the service life of air filter, and make space utilization more reasonable.
Bushing includes external bushing 209, neck bush 207 and the bushing rubber being placed between external bushing 209 and neck bush 207
208, external bushing 209 is plugged in sleeve 205, and centre bore is arranged at the axial direction of neck bush 207.The bush structure processing letter of this structure
Single, both can protect bushing rubber 208, and can preferably play buffering and damping effect again.
Bushing can only include external bushing 209 and bushing rubber 208, or only includes neck bush 207 and bushing rubber
208, this kind of structure the former easily cause the endoporus of bushing rubber 208 and be worn, the company of the latter's bushing rubber 208 and sleeve 205
Connect inconvenience, the two all reduces the radial rigidity of bushing simultaneously, when vibratory impulse is larger, easily causes bushing rubber 208
Inefficacy, do not have the effect of effective buffer shock-absorbing.
External bushing 209, neck bush 207 and bushing rubber 208 three sulfuration are into a single integrated structure.This structure bushing rubber 208
Do not need separately fabricated mould, shaping is simple, and save bushing assembling link, improve car load efficiency of assembling.External bushing 209, interior
Bushing 207 and bushing rubber 208 three can also separately formed after reassemble integral.
External bushing 209 and sleeve 205 interference fit.This structure saves the axial and circumferential positioning dress of bushing and sleeve 205
Put, directly passing through interference fit will the two position, convenient for assembly.Bushing and sleeve 205 can also pass through jackscrew or key pin
Structure is positioned.
Specifically, external bushing 209 passes through diameter reducing process, is assemblied in sleeve 205.
Bushing rubber 208 is provided with several grooves, groove along bushing rubber 208 axially through.This structure increases bushing
The elastic deformation space of rubber 208, to improve buffering and the damping effect of bushing.
Although the present invention is described with reference to above example, the present invention is not limited to above-described embodiment, and
Only limited by claim, those of ordinary skill in the art easily can modify to it and change, but and without departing from
The essential idea of the present invention and scope.
