Abstract
The utility model discloses a stabilizing rod support with high lateral stiffness and low torsional stiffness, which comprises a shaft sleeve type support and a lug boss arranged on the inner wall of an axle hole of the shaft sleeve type support. Because the stabilizing rod support is a rubber body, lower torsional stiffness can be realized through improving rubber compounding, but high axial and radial stiffness can be realized through arranging the lug boss on an inner hole and adding a metal framework in the rubber body, thereby the utility model not only ensures no overmuch axial float of a stabilizing rod, but also improves the ride comfort of automobiles and is simple and easy to operate.
Description
Technical field
The utility model belongs to auto parts and components, is specifically related to the bracing or strutting arrangement of the stabilizer rod on a kind of suspension.
Background technology
For increasing the roll angular rigidity of automobile, on suspension, add stabilizer bar device usually, stabilizer rod then is to be connected by the stabilizer rod bearing with vehicle frame, the stabilizer rod bearing not only plays the effect of fixing-stable bar, can also absorb energy, the load impacting of buffering stabilizer rod.Stabilizer rod bearing torsional stiffness is low more, ride comfort to automobile is favourable more, but in order to limit the horizontal and vertical degree of freedom of stabilizer rod, prevents too much displacement, and have influence on the function of suspension, require the stabilizer rod bearing to have higher axial stiffness and radial rigidity.Existing stabilizer rod bearing is the axle sleeve type structure, the spacing dependence stabilizer rod of the degree of freedom that stabilizer rod is horizontal and vertical and the spacing realization of axle head between the stabilizer rod bearing, but the axially high and radial rigidity of this stabilizer rod bearing is lower, and service life is lower relatively.
Summary of the invention
The purpose of this utility model be to provide a kind of high axially, the stabilizer rod bearing of radial rigidity and low torsional stiffness, can guarantee that stabilizer rod axially not having too much play, can also improve the ride comfort of automobile.
The technical solution of the utility model is: high transverse stiffness hangs down torsional stiffness stabilizer rod bearing, and it comprises the axle sleeve type bearing, and the shaft hole inner wall of axle sleeve type bearing is provided with boss.
Described axle sleeve type bearing is the axle sleeve type rubber bodies, is provided with metallic framework in the axle sleeve type rubber bodies, and axle sleeve type rubber body wall is axially established open slot.
The stabilizer rod bearing is because of being rubber bodies, thus lower torsional stiffness can realize by improving rubber compounding, but high axially, radial rigidity then is by realizing boss being set on the endoporus and adding metallic framework in rubber bodies.
This utility model of evidence is when torsional stiffness has only 2N.m/deg, and axial stiffness and radial rigidity can reach 300N/mm respectively and more than the 7500N/mm, realize functional requirement well.It can guarantee that stabilizer rod axially not having too much play, can also improve the ride comfort of automobile, and simple.It is simple, and cost is low.
Description of drawings

Fig. 2 is Figure 1A-A cutaway view.
The assembling scheme drawing of Fig. 3 the utility model and stabilizer rod.
The specific embodiment
As shown in Figure 1, 2, the axle sleeve type bearing is an axle sleeve type rubber bodies 1, is provided with metallic framework 2 in the axle sleeve type rubber bodies 1, and axle sleeve type rubber bodies 1 wall is axially established open slot 5.The shaft hole inner wall of axle sleeve type bearing 1 is provided with boss 3.The boss cross section is trapezoidal.Boss 3 on the axle sleeve type bearing shaft hole inner wall is relative with open slot 5.
As shown in Figure 3, offer the boss 3 shape groove opposite of establishing on the shaft hole inner wall with axle sleeve type bearing 1 on the stabilizer rod 4, groove during assembling on the stabilizer rod 4 cooperates with boss 3, to reach the purpose of restriction stabilizer rod horizontal degree of freedom, prevents that too much displacement laterally appears in stabilizer rod when stressed.2 of metallic frameworks in the rubber bodies have played and have strengthened the stabilizer rod bearing axially and the effect of radial rigidity.
Claims (4)
