The upper supporting rod has the advantages of being simple and compact in structure, convenient to machine, good in force transmission and safety, high in flexibility, low in noise generated in movement, convenient to maintain later, and low in manufacturing cost.

Description

A kind of upper strut
Technical field
The utility model relates to Independent Suspension field, is specially a kind of novel upper strut.
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 requirements such as driving safety and road-holding property.Independent suspension can the use on vehicle become development tendency.
Independent suspension structure type is a lot, by wheel movement form, divides and can be divided into four classes: 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 that wheel moves along stub (candle type suspension, McPherson strut); (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 when Suspension Deformation, and wheel plane tilts generation and causes 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.During 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 comprised of Top Crossbeam, upper strut, lower cross arm and lower supporting rod.Above strut version and arrange the stability of controlling, traveling comfort and the safety that directly affects car load.But traditional strut design structure is heavy, and difficulty of processing is large, and strut and subframe joint gap are larger, and can left and right play while rotating, 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 upper strut of the little and convenient later maintenance of the noise that produces during 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 upper strut, comprise single armed, described single armed one end is provided with step through-hole, in described step through-hole, be equiped with the coupling assembling being connected with subframe, the single armed other end is provided with two tapped bore that are connected with Top Crossbeam, and the line of centers of described step through-hole and tapped bore is positioned at same plane identical with the bearing of trend of single armed.
As to further improvement of the utility model:
Described coupling assembling comprises anti-wearing liner, wear-resistant gasket and tie bolt, described anti-wearing liner is located in described step through-hole, wear-resistant gasket is provided with two, is divided into the two ends of anti-wearing liner and is positioned at outside described step through-hole, and tie bolt is arranged in the centre hole of anti-wearing liner and wear-resistant gasket.
Described anti-wearing liner and described step through-hole interference fit.
The center, left and right of upper strut and Top Crossbeam is all positioned at XY plane.
Angle between upper strut and Top Crossbeam is 68 °.
Described single armed one end is provided with to the overhanging connection boss of a side, and described step through-hole is located in described connection boss.
The described single armed other end is provided with to the overhanging boss of opposite side, and described tapped bore is located on described boss.
Compared with prior art, the utility model has the advantage of:
Upper strut of the present utility model, its main body is a single armed, in single armed one end, step through-hole is set and coupling assembling is installed and be connected with subframe, the other end arranges two tapped bore and is rigidly connected by bolt and Top Crossbeam, and bearing capacity performance is good, and the connection line of centers at two ends is all positioned at same plane, it is simple and compact for structure, process easyly, up-and-down movement and power transmission are steady, and resistance is little; Anti-wearing liner in coupling assembling and step through-hole interference fit, make it to become an indivisible integral body, and compact conformation, does not rock, and is beneficial to later maintenance, only need change anti-wearing liner.And can adopt forging die batch manufacturing, effectively reduce manufacturing cost, improve part quality, make its with subframe and steering swivel to be connected precision high, sensitieness is good, the noise of generation is little, the traveling comfort of driving can improve greatly.

The specific embodiment
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, a kind of upper strut of the present utility model, comprises single armed 1, anti-wearing liner 3, tie bolt 4 and wear-resistant gasket 2.The cross-sectional plane of single armed 1 takes the shape of the letter U, in one end of single armed 1, arrange to the overhanging connection boss of a side, connect on boss step through-hole 5 is set, the other end of single armed 1 also arranges to the overhanging boss of opposite side, on boss, offer 2 tapped bore 6, the line of centers of step through-hole 5 and tapped bore 6 is positioned at same plane identical with the bearing of trend of single armed 1, can adopt forging die batch manufacturing, effectively reduce manufacturing cost, improve part quality.In the present embodiment, anti-wearing liner 3 interference are installed in step through-hole 5, make it to become an indivisible integral body, and compact conformation, does not rock, and is beneficial to later maintenance, only need change anti-wearing liner.Wear-resistant gasket 2 is provided with two both sides that are divided into anti-wearing liner 3, makes anti-wearing liner 3 and subframe clamping, can not become flexible and rock, the subframe that rubs in the time of more can be because of Top Crossbeam up-and-down movement, thus provide advantage for the maintenance in later stage.Tie bolt 4 is rigidly connected through centre hole and the subframe of wear-resistant gasket 2 and anti-wearing liner 3.In the present embodiment, 10.9 grades of the performance rates of tie bolt 4, thus bearing capacity aspect is guaranteed, safety performance is improved.In the present embodiment, tapped bore 6 is rigidly connected by bolt and Top Crossbeam, and power transmission and bearing capacity are extremely strong, connects simple compactness, and safety performance is guaranteed.
When upper strut of the present utility model is used, the angle of itself and Top Crossbeam 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.
When upper strut of the present utility model is used for independent suspension system, upper and lower two transverse arm, steering swivel and vehicle frame form four-bar linkage, and the left and right sides is independent mutually, is independent of each other, simple and compact for structure, be convenient to die forging and carry out batch machining production, can effectively reduce manufacturing cost, improve part quality, make its with subframe and steering swivel to be connected precision high, sensitieness is good, and the noise of generation is little, greatly improves the traveling comfort of driving.
