Description
Technical field
The utility model relates to Independent Suspension field, is specially a kind of novel Top Crossbeam.
Background technology
Car speed is along with the development of freeway net improves constantly, and people enjoy concern to travel road-holding property and the driving safety of vehicle, make dependent suspension vehicle can not meet the aspect such as driving safety and road-holding property requirement.Independent suspension can the use on vehicle become development tendency.
Independent suspension structure type is a lot, divides and can be divided into four classes by wheel movement form: the suspension (independent suspension by swinging arms) that (1) wheel swings in automobile Transverse plane; (2) suspension (independent suspension by trailing arms) that wheel swings in automobile longitudinal plane; (3) suspension (candle type suspension, McPherson strut) that wheel moves along stub; (4) suspension (single oblique arm type independent suspension) that wheel swings in the oblique plane of automobile.Independent suspension by swinging arms is divided into again two kinds of single swing arm type and double wish-bone arm types.Single transverse arm type suspension is in the time of Suspension Deformation, and wheel plane tilts generation and cause tire with respect to ground lateral sliding, destroys tire and ground and adheres to, and makes wear on tyres serious, and larger variation occurs for Kingpin inclination angle and camber angle while turning to.Wishbone-type independent suspension is divided into again isometric double wish-bone arm type and not isometric wishbone-type independent suspension.When isometric wishbone suspension wheel bob there is larger variation in wheelspan, and this will increase the possibility of wheel lateral sliding.The two transverse arms of not isometric formula can make the angle of wheel and stub and the variation of wheelspan all not too large, and the two transverse arms of not isometric formula are made up of Top Crossbeam, upper strut, lower cross arm and lower supporting rod.So the version of Top Crossbeam and layout directly affect manipulation stability, traveling comfort and the safety of car load.But traditional transverse arm design structure heaviness, difficulty of processing is large, transverse arm is larger by torsion bar and subframe joint gap, and can left and right while rotating play, sensitivity is poor, easily produces noise, and whole suspension property is declined, and has potential safety hazard.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of simple and compact for structure, process easy, power transmission and safety performance good, highly sensitive, the Top Crossbeam of the little and convenient later maintenance of the noise that produces when motion, low cost of manufacture.
For solving the problems of the technologies described above, the technical scheme the utility model proposes is:
A kind of Top Crossbeam, comprise in-line single armed and stub bulb, described in-line single armed one end is provided with the splined hole being connected with torsion bar, the in-line single armed other end is provided with tapped bore, described stub bulb is installed in described tapped bore, and one section by stub bulb on in-line single armed is provided with two through holes that are connected with upper strut.
As to further improvement of the utility model:
Described stub bulb adopts without stub formula steering structure ball end.
Described stub bulb upper end is cylindrical and be provided with the screw thread being connected with tapped bore, and lower end is tapered and be provided with the screw thread being connected with steering swivel taper hole.
Described tapped bore is of a size of M56 × 1.5.
Angle between Top Crossbeam and upper strut is 68 °.
The Axis Extension direction of described through hole and splined hole is roughly the same, and through hole is spatially substantially vertical with the axis of tapped bore.
Compared with prior art, the utility model has the advantage of:
Top Crossbeam of the present utility model, simple and compact for structure, easy to process.Its one end arranges splined hole and is connected with torsion bar, and the other end arranges tapped bore and is connected with stub bulb upper end, makes it to become torsion bar spring independent suspension, and elastic performance is good, and traveling comfort is good, and it is little to take up room, and is beneficial to layout.Stub bulb adopts without stub formula steering structure ball end, has both made the spindle central of upper and lower transverse arm motion, the effect of steering yoke bolt of having held concurrently again.The angle of Top Crossbeam and upper strut is 68 °, and center, two ends is at same plane, make it up-and-down movement steady, resistance is little, and transmission force property is good, and can adopt die forging to carry out batch manufacturing, can effectively reduce manufacturing cost, improve part quality, highly sensitive, the noise producing is little, can improve the traveling comfort of driving.

Detailed description of the invention
For the ease of understanding the utility model, below in connection with Figure of description and preferred embodiment, the utility model is done more comprehensively, described meticulously, but protection domain of the present utility model is not limited to following specific embodiment.
As depicted in figs. 1 and 2, Top Crossbeam of the present utility model, comprises in-line single armed 1 and stub bulb 2.In-line single armed 1 one end is provided with splined hole 3, and in-line single armed 1 is connected with torsion bar by spline, can damping again can power transmission.In-line single armed 1 other end is provided with tapped bore 5, and stub bulb 2 upper ends are installed in tapped bore 5, and one section by stub bulb 2 on in-line single armed 1 is provided with two through holes 4 that are connected with upper strut.In the present embodiment, bolt is rigidly connected through through hole 4 and upper strut, 10.9 grades of the performance rates of bolt, thus can ensure bearing capacity, improve safety performance.
In the present embodiment, through hole 4 is roughly the same with the Axis Extension direction of splined hole 3, and through hole 4 is spatially substantially vertical with the axis of tapped bore 5.When Top Crossbeam of the present utility model is installed and used, the angle of itself and upper strut is 68 °, and center, two ends is in same plane (XY plane), and up-and-down movement is steady, and resistance is little, and transmission force property is good.And can adopt die forging to carry out batch manufacturing processing, effectively reduce manufacturing cost, improve part quality.
In the present embodiment, splined hole 3 is with torsion bar by inside and outside spline joint, and torsion bar two ends adjust arm of force torsion bar to adjust power support to be connected with subframe by lining and torsion bar, and simple in structure, elastic performance is good, and traveling comfort is good, and it is little to take up room, and is beneficial to layout.
In the present embodiment, stub bulb 2 adopts without stub formula steering structure ball end.Its upper end is cylindrical, is installed in tapped bore 5 by screw thread, and tapped bore 5 is of a size of M56 × 1.5.Stub bulb 2 lower ends are tapered and be provided with screw thread, are threaded and clamp by nut with steering swivel taper hole.In the middle of steering swivel, form bulb pair, can ensure the bob of Top Crossbeam, can ensure again the turning efficiency that steering swivel is very good, simple and practical.
When Top Crossbeam of the present utility model is used for independent suspension system, upper and lower two transverse arms, steering swivel and vehicle frame form four-bar linkage, and the left and right sides is independent mutually, is independent of each other.
