Abstract
The invention discloses an upper damping support for an automobile rear suspension, which is used for connecting an automobile rear suspension shock absorber and an automobile body and comprises a casing with a cavity. An elastic block is embedded in the cavity of the casing, a piston rod of the rear suspension shock absorber penetrates through the casing and the elastic block, a connection plate is embedded in the elastic block, and the piston rod penetrates through the connection plate to be fastened and connected through a nut. By means of the technical scheme, the elastic block is utilized to separate the piston rod of the shock absorber from the automobile body, so that rigidity contact between the rear suspension and the automobile body is avoided, and the embedded elastic block is deformed to buffer impact and reduce shock. Due to the large size of the embedded elastic block, the embedded connection plate and the piston rod can have larger moving amplitude and release certain moving space for the piston rod of the shock absorber. Therefore, the upper damping support is good in damping effect, thereby greatly reducing impact on the automobile when the shock absorber moves.
Description
Technical field
The present invention relates to the technical field of auto parts and components, specifically, the present invention relates to a kind of rear overhang rack and use the damping support.
Background technology
At present, rear overhang rack is to be connected with auto body through the metallic support seat, contacts with rigidity between the metal for fear of metal; Between metallic support seat and vehicle body, be provided with one deck rubber elastic element, but adopt the connection mode of this kind structure, because supporting seat is a rigid body; For being rigidly connected, and the damping effect of rubber elastic element is limited, causes the amplitude of rear suspension and body contact place bumper and absorbing shock little between the piston rod of rear suspension bumper and the supporting seat; When automotive operation; Bumper inevitably can produce bigger impact to vehicle body, causes the damage of vehicle body, also can influence automobile handling and back row's travelling comfort.
The invention provides the version that supports on a kind of rear overhang rack,
Summary of the invention
Technical matters to be solved by this invention provides damping support on a kind of rear overhang rack; Not only can avoid rear suspension to contact with rigidity between the vehicle body; The amplitude that also is rear suspension and body contact place bumper and absorbing shock increases, thereby reduces the impact that bumper produces vehicle body greatly.
In order to solve the problems of the technologies described above; The technical scheme that the present invention adopted is: a kind of rear overhang rack is used damping and is supported, and is used for being connected between rear overhang rack bumper and the auto body, saidly goes up damping and supports and comprise the housing that is provided with cavity in; Cavity at this housing is embedded with elastomer block; The piston rod of said rear suspension bumper passes said housing and elastomer block, on said elastomer block, is embedded with connecting panel, and said piston rod passes said connecting panel and is fastenedly connected through nut.
The cavity inner wall of said elastomer block and said housing fits tightly.
The outer wall of said housing is provided with and said auto body bonded assembly engaging lug.
The material of said elastomer block is rubber or microvoid polyurethane.
Said housing is an aluminum casting.
The present invention adopts technique scheme, and is simple in structure, easy for installation; Through using elastomer block, not only can avoid rear suspension to contact, and embedded elastomer block can produce distortion with rigidity between the vehicle body with piston lever of reducer and vehicle body isolation; Be out of shape to relax to impact through this and reduce vibrations; Because the volume of embedded elastomer block is bigger, can allow embedded connecting panel and piston rod that bigger motion amplitude is arranged, for piston lever of reducer discharges certain activity space; So the effect of damping is better, thereby reduce the impact that bumper when motion produces vehicle body greatly.

The specific embodiment
As shown in Figure 1; A kind of rear overhang rack of the present invention is used damping and is supported, and is used for being connected between rear overhang rack bumper and the auto body 1, and last damping support comprises the housing 3 that is provided with cavity in; Cavity at this housing 3 is embedded with elastomer block 4; The cavity of housing 3 is cylindrical, and the cavity shape of the shape of elastomer block 4 and housing 3 is suitable, and elastomer block 4 fits tightly with the cavity inner wall of housing 3.Two ends at housing 3 have through hole; On elastomer block 4, also be provided with through hole; The piston rod 5 of rear suspension bumper passes housing 3 and elastomer block 4 through through hole, and on elastomer block 4, also is embedded with steel connecting panel 6, and piston rod 5 also passes this connecting panel 6 and is fastenedly connected with it through nut III10.When housing 3 receives from ground-surface impact; Piston lever of reducer 5 produces axially, radially perhaps twisting motion; Because embedded connecting panel 6 is fixed through nut III10 with piston lever of reducer 5, therefore embedded connecting panel 6 also produces corresponding motion in housing 3, at this moment; Embedded elastomer block 4 produces distortion, is out of shape to relax to impact through this to reduce vibrations.Because the volume of embedded elastomer block 4 is bigger, can allow embedded connecting panel 6 bigger motion amplitude to be arranged, so the effect of damping is better with piston rod 5.
As shown in Figure 2, being shaped as of housing 3 is cylindrical, on the outer wall of housing 3, is provided with 12, two engaging lugs 12 of two engaging lugs of auto body 1 bonded assembly to be fastenedly connected through bolt I 2, bolt II7 and nut I 11, nut II8 and vehicle body 1 respectively.And, be provided with an end cap 9 on the top of housing 3, on this end cap 9, have through hole; Supply piston rod 5 to pass, housing 3 is an aluminum casting with end cap 9, and the material of embedded elastomer block 4 can be rubber or microvoid polyurethane; Perhaps select other to have the elastomeric material of damping performance according to cost requirement; Embedded elastic body covers end cap 9 then with being pressed in the housing 3 after embedded connecting panel 6 parcels, end cap 9 is encased and fix through the limit of rolling housing 3.
The most fragile part of damping support is embedded elastomer block 4 on the basis, after damaging like embedded elastomer block 4, and can
Utilize specialized equipment that housing 3 is cut from oral area, embedded connecting panel 6 and end cap 9 all can reuse.Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or design of the present invention and technical scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
