The position of damper, prevent from shaking it is excessive, damper be detached from, damping failure, shock relieve vent damper receive extruding and impact when
Time increases deformation space so that damper can fully absorb vibrations momentum, reduce vibration energy, vibrating noise be reduced, every
Radial reinforcing plate is set on the different location of a shock relieve vent, increases the diametrical rigidity of damper, it is whole to enhance damper
The stability of body, on the one hand the stabiliser bar in radial reinforcing plate can be used to support shock relieve vent when damper is pressurized serious, another
Aspect is when damper shakes, and stabiliser bar can distribute vibrations momentum in the form of shake, and each stabiliser bar is in not Tongfang
It is shaken to different periods, suffered vibrations pressure can be neutralized mutually, played good stable damper and reduce the effect of vibrations.
Preferably, the through-hole section is regular hexagon.Section is regular hexagon, and each side is with holder axle center at positive triangle
Shape is stablized effective the most.
Preferably, the damping number of perforations is 8.Shock relieve vent is arranged to 8 in right amount, and it is simple that angle is easy arrangement.
Preferably, each shock relieve vent is circumferentially uniformly distributed along shock absorber body.Shock relieve vent is equally spaced for damper
When stress, shock relieve vent uniform pickup shakes momentum.
Preferably, the stabiliser bar runs through radial reinforcing plate, the stabiliser bar is interference fitted with radial strengthening version.Stablize
It is to prevent the two from shaking together that bar, which is not cast with radial reinforcing plate whole, does not have shock absorbing effect.
Preferably, the shock absorber body, upper annular stop convex body, lower annular stop convex body and each radial reinforcing plate are
Integrated formed structure.Shock absorber body, upper annular stop convex body, lower annular stop convex body and radial reinforcing plate are integrally formed knot
Structure is easily manufactured, reduces union piece.
The utility model has the beneficial effects that：Through-hole section is regular polygon, and intermediate portion was in circular support
It is full of mated condition, each apex angle and the circular support of regular polygon be in clearance fit state, are conducive to damper deformation and absorb rush
Energy is hit, shock relieve vent increases deformation space when damper receives extruding and impact so that damper can fully absorb shake
Impetus reduces vibration energy, reduces vibrating noise, and radial reinforcing plate is arranged on the different location of each shock relieve vent, increases
Damper diametrical rigidity, stabiliser bar can be used to support shock relieve vent when damper is pressurized serious, not only in damper
When vibrations, stabiliser bar can distribute vibrations momentum in the form of shake, and each stabiliser bar is shaken in different directions different periods,
Suffered vibrations pressure can be neutralized mutually, good stable damper is played and reduces the effect of vibrations, enhance damper entirety
Stability.
