Description
Technical field
The utility model belongs to the lightweights products such as new-energy automobile ABS and EVP installation damping appliance technology, especially
It is related to a kind of Low rigidity damping device.
Background technology
Based on new energy vehicle to the NVH performance requirements of vehicle, in cabin interior, people's subjective sensation should not have pedal,
Steering wheel is shaken phenomenon, and must not have the apparent abnormal sound etc. bad.Hereby, it is desirable that a brand-new damper of exploitation is used for
The shock insulation of the power sources assembly such as ABS and EVP.
The content of the invention
The purpose of this utility model is that solving the problems, such as techniques discussed above, it is mesh to provide a kind of reduction damper stiffness
, ensure its enough installation strength, meet its horizontal and side direction installation, ensure its reliability.This structure design is realized low
Rigidity, high intensity, the effect of high shock insulation, the Low rigidity dampening arrangement of raising vehicle NVH performances, technical solution are as follows：
Low rigidity damping device, which is characterized in that including damper, product piece, stent and bolt, the damper is set
It is placed between stent and product piece；Mounting groove is offered on the outer surface of the damper, is offered at the center of damper
Endoporus offers the cavity of staggered cross setting on damper；Bracket holes are provided on the stent, damper passes through installation
Slot is placed in bracket holes, will be connected to after the endoporus of one end insertion damper of bolt in product piece.
Preferred embodiment is that the bolt includes threaded area, ring flange, supporting section and diameter segment, and the ring flange is
Be pressed the positioning of damper end, the supporting section with the endoporus of damper is tangent contacts, support the weight of entire whole device
Amount；The diameter segment is located in endoporus and is in gap state with the endoporus of damper.
Preferred embodiment is that the endoporus is hexagonal hole.
Preferred embodiment is to be provided with reinforcing rib on the damper.
Preferred embodiment is that the cavity is fan-shaped chamber.
Low rigidity dampening arrangement provided by the utility model, when in use, the setting of cavity is to reduce just
In terms of degree, reduce the rigidity at its mounting groove.The setting of endoporus is more yielding in terms of structural principle, only damper is allowed to have
Enough elastic deformation spaces can play good shock-absorbing.
The utility model ring flange is the positioning of press fitting damper end, its function of supporting section is and damper hexagonal inner hole
Tangent contact supports the weight of entire product piece；Diameter segment is with damper hexagonal inner hole in gap state, major function reality
It is existing, it in product piece startup, is stopped moment, vibrations are larger, and damper is needed to have enough deflections to absorb energy impact, together
When, the displacement for preventing product piece again is excessive, causes the failure modes such as peripheral elements shocks other with vehicle.
The utility model reinforcing rib ensures after the mounting groove of damper is packed into bracket holes that both ends rigidity is larger, stent
It is not easy to come off at mounting groove.
The beneficial effects of the utility model are：For the purpose of reducing damper stiffness, ensure its enough installation strength, meet
Its horizontal and side direction installation, ensures its reliability.This structure design, realizes Low rigidity, high intensity, and the effect of high shock insulation carries
High vehicle NVH performances.

Specific embodiment
With reference to Fig. 1 to Fig. 4 specific illustrative embodiment：
Low rigidity damping device, including damper 2, product piece 1, stent 3 and bolt 4, the damper 2 is arranged at branch
Between frame 3 and product piece 1；Mounting groove 24 is offered on the outer surface of the damper 2, is offered at the center of damper interior
Hole 21 offers the cavity 23 of staggered cross setting on damper；Bracket holes are provided on the stent 3, damper passes through
Mounting groove 24 is placed in bracket holes, will be connected to after the endoporus of one end insertion damper of bolt in product piece.
Preferred embodiment is that the bolt includes threaded area 43, ring flange 42, supporting section 41 and diameter segment 44, described
Ring flange is the positioning of press fitting damper end, the supporting section with the endoporus of damper is tangent contacts, support entire
The weight of device；The diameter segment is located in endoporus and is in gap state with the endoporus of damper.
Preferred embodiment is that the endoporus is hexagonal hole.
Preferred embodiment is that reinforcing rib 22 is provided on the damper.
Preferred embodiment is that the cavity is fan-shaped chamber.
Shock absorber structure designs, and in terms of reducing rigidity, is respectively provided with the fan-shaped chamber of opposed staggered cross depth, makes
Rigidity at its mounting groove 24 reduces, meanwhile, to ensure its rubber structural strength, design structure reinforcing rib 22, and guarantor will
After the mounting groove slot of damper is packed into 3 hole of stent, both ends rigidity is larger, and stent 3 is not easy to come off at mounting groove 24.Meanwhile
The endoporus 21 of damper is designed as hexagon, it is more yielding in terms of structural principle, damper is only allowed there are enough elasticity changes
Shape space can play good shock-absorbing.
3 structure design of bolt, threaded area 43 may be directly threaded into the threaded hole of installation product piece, by the platform of thread head
Rank positions, and ring flange is the positioning of press fitting damper end；Supporting section, function are the hexagonal inner hole phase cut-graftings with damper
It touches, supports the weight of entire product piece；The hexagonal inner hole of diameter segment and damper is in gap state, and major function is realized,
It in product piece startup, is stopped moment, vibrations are larger, and damper 2 is needed to have enough deflections to absorb energy impact, together
When, the displacement for preventing product piece again is excessive, causes the failure modes such as peripheral elements shocks other with vehicle；
During assembling, damper 2 is packed into 3 hole of stent first, its mounting groove 24 is made effectively to be caught in bracket holes；Again by bolt
4 insertion dampers 2, are directly threaded into the respective screw hole of product piece 1.Stent 3 is directly connected with vehicle body, and then good
Isolation property.Incompetent horizontal direction or side direction installation, ensure the reliability of its installation and shock insulation rate.
