Description

Low rigidity damper

Technical field

The utility model belongs to damper appliance technology more particularly to a kind of Low rigidity damper.

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 it is bad to have apparent abnormal sound etc..Hereby, it is desirable that a completely new damper of exploitation is used for The shock insulation of the power sources assembly such as ABS and EVP.

Invention content

Utility model aims to solve techniques discussed above problem, it is mesh to provide a kind of reduction damper stiffness , ensure its enough installation strength, improves the Low rigidity damper of vehicle NVH performances, its technical solution is as follows：

Low rigidity damper, which is characterized in that offer mounting groove on the outer surface of damper, opened at the center of damper Equipped with endoporus, the cavity of staggered cross setting is offered on 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.

Preferred embodiment is that damper is made of silicon rubber, and total is integral type sulfidization molding.

Low rigidity damper provided by the utility model, when in use, the setting of cavity is to reduce rigidity side Face makes the rigidity at its mounting groove reduce.The setting of endoporus is more yielding in terms of structural principle, and damper is only allowed to have enough Elastic deformation space, good shock-absorbing can be played.

The utility model reinforcing rib ensures after the mounting groove of damper is packed into bracket holes that both ends rigidity is larger, holder It is not easy to fall off from mounting groove.

The utility model has the beneficial effects that：For the purpose of reducing damper stiffness, ensure its enough installation strength, improves Vehicle NVH performances.

Specific implementation mode

With reference to Fig. 1 to Fig. 4 specific illustrative embodiment：

Low rigidity damping device, including damper 2, product piece 1, holder 3 and bolt 4, the damper 2 are set to 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 holder 3, damper passes through Mounting groove 24 is placed in bracket holes, is connected in product piece after the endoporus of damper is inserted into one end of bolt.

Preferred embodiment is, 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 protecting will After the mounting groove slot of damper is packed into 3 hole of holder, both ends rigidity is larger, and holder 3 is not easy to fall off from mounting groove 24.Meanwhile The endoporus 21 for designing damper is hexagon, more yielding in terms of structural principle, and damper is only allowed to have enough elasticity to become 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, lean on 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, it prevents the displacement of product piece excessive again, causes and the failure modes such as the other peripheral elements shocks of vehicle, control diameter segment 44 Gap with hexagonal inner hole 21 is 1mm, makes the control of product maximum displacement in 1mm；

When assembly, damper 2 is packed into 3 hole of holder first, its mounting groove 24 is made effectively to be caught in bracket holes；Again by bolt 4 are inserted into damper 2, are directly threaded into the respective screw hole of product piece 1.Holder 3 is directly connect with vehicle body, and then reaches good Isolation property.Incompetent horizontal direction or side direction installation, ensure the reliability and shock insulation rate of its installation.

Damper is good using elastic property, and weather resistance is strong, the good silicon rubber system of resistance to ozone, high and low temperature resistance At total is integral type sulfidization molding.
