Description
Technical field
The utility model relates to a kind of arm axle connection structure of automotive suspension upper suspension arm, belongs to technical field of automobile parts.
Background technology
The various power acted on wheel, as guiding and the force transfer element of automobile suspension system, are passed to vehicle body by automotive suspension upper suspension arm (Control arm also claim Triangular Arm), ensure that wheel is by certain track motion simultaneously.Control arm assembly by housing, ball pin and arm axle three part form, respectively by suspension ball pin (hinge) or arm axle lining wheel and flexible chassis are linked together.Control arm assembly (comprising the suspension ball pin and arm axle that are attached thereto) should have enough rigidity, intensity and service life.
Arm axle two ends and the housing of existing automotive suspension upper suspension arm assemble, general employing nut fixes rigid connection (see accompanying drawing 1), because of the kinetic vehicle body reverse stress change of automobile, produce larger vibration, and damping property is poor, very easily cause its torsional fracture, be directly connected to automobile safety under steam.
Summary of the invention
The purpose of this utility model is: provide that a kind of structure is simple, practicality good, the kinetic vehicle body reverse stress change of rigid connection because of automobile is fixed to solve existing arm axle, produce larger vibration, and damping property is poor, very easily cause its torsional fracture, be directly connected to the arm axle connection structure of the automotive suspension upper suspension arm of ride safety of automobile problem.
The utility model realizes above-mentioned purpose by following scheme:
An arm axle connection structure for automotive suspension upper suspension arm, comprises Control arm arm axle and suspension upper suspension arm, it is characterized in that: the arm fork head of suspension upper suspension arm upper end is respectively arranged with assembly opening, is provided with Control arm arm axle in assembly opening by shock-absorbing sleeve; The two ends of Control arm arm axle extend to shock-absorbing sleeve outer end respectively, and the Control arm arm axle termination extending to shock-absorbing sleeve outer end is provided with the nut that is locked; Described shock-absorbing sleeve is made up of damping steel bushing and resilient bushing; Damping steel bushing and resilient bushing respectively in "
⊥" shape, the circumferential outer surface of resilient bushing is provided with groove, and damping steel bushing is sleeved on resilient bushing by groove.
The described Control arm arm axle be locked between nut and shock-absorbing sleeve is provided with tightening cushion.
Described tightening cushion cross section is curved, and tightening cushion adopts elastomeric material to make.
Described resilient bushing adopts nanofiber rubber composite to make.
The utility model has the advantage of:
The arm axle connection structure structure of this automotive suspension upper suspension arm is simple, practicality good, Control arm arm axle is arranged in suspension upper suspension arm by shock-absorbing sleeve, because shock-absorbing sleeve has the properties such as excellent elasticity, conductance that suppleness is high and excellent, thus Control arm is connected with vehicle body be provided with good damping performance.Solve existing arm axle and fix the kinetic vehicle body reverse stress change of rigid connection because of automobile, produce larger vibration, and damping property is poor, very easily causes its torsional fracture, is directly connected to the safety problem of running car.To prolongation product service life and raising traffic safety, there is positive effect.
Accompanying drawing explanation
Fig. 1 is that existing arm axle adopts nut to fix rigidly connected structural representation.
Fig. 2 is sectional structure schematic diagram of the present utility model;
Fig. 3 is the structure for amplifying schematic diagram at Fig. 2 A place.
In figure: 1, Control arm arm axle, 2, suspension upper suspension arm, 3, setting nut, 4, be locked nut, 5, damping steel bushing, 6, resilient bushing, 7, tightening cushion.
Detailed description of the invention
The arm axle connection structure of this automotive suspension upper suspension arm comprises Control arm arm axle 1 and suspension upper suspension arm 2.The arm fork head of suspension upper suspension arm 2 upper end is respectively arranged with assembly opening, is provided with Control arm arm axle 1 in assembly opening by shock-absorbing sleeve.Control arm arm axle 1 adopts alloy steel precision cast, to improve intensity, improves yield tensile ratio.The two ends of Control arm arm axle 1 extend to shock-absorbing sleeve outer end respectively, and Control arm arm axle 1 termination extending to shock-absorbing sleeve outer end is provided with the nut 4 that is locked.Shock-absorbing sleeve is made up of damping steel bushing 5 and resilient bushing 6; Damping steel bushing 5 and resilient bushing 6 respectively in "
⊥" shape, the circumferential outer surface of resilient bushing 6 is provided with groove, and damping steel bushing 5 is sleeved on resilient bushing 6 by groove.The Control arm arm axle 1 be locked between nut 4 and shock-absorbing sleeve is provided with tightening cushion 7.Tightening cushion 7 cross section is curved, and tightening cushion 7 adopts elastomeric material to make.
The resilient bushing 6 of this automotive suspension upper suspension arm adopts nanofiber rubber composite to make.There is in working process the properties such as the high and excellent conductance of flexible toughness, thus the damping performance that Control arm is connected with vehicle body can be increased.Simultaneously, owing to the Control arm arm axle 1 that is locked between nut 4 and shock-absorbing sleeve being provided with the tightening cushion 7 that elastomeric material is made, and the cross section of tightening cushion 7 is curved, by the squeese pressure of tightening cushion 7 in working process, compensating action can be played to resilient bushing 6, resilient bushing 6 is fully contacted with Control arm arm axle 1, plays and relax the effect of shock and vibration, thus Control arm is connected with vehicle body be provided with good damping performance.Solve existing arm axle thus and fix the kinetic vehicle body reverse stress change of rigid connection because of automobile, produce larger vibration, and damping property is poor, very easily causes its torsional fracture, is directly connected to the safety problem of running car.The arm axle connection structure structure of this automotive suspension upper suspension arm is simple, practicality good, has positive effect to prolongation product service life and raising traffic safety.
