Abstract
The utility model relates to a torque rubber core for truck, which comprises a central axis, a loop which is sheathed outside the central axis. The loop is formed by binding together an outer ring, an elastic body and an inner ring in order. The utility model is characterized in that the middle part of the central axis is in a spherical hump shape, and the spherical hump outer diameter is sheathed with the inner ring. A bowl shaped elastic body tightly matched with the inner ring and the central axis is arranged on the two sides of the spherical hump. The central axis of the utility model can steer wobbling. The utility model has the advantages of reducing direct stress of the rubber core, extending the service life of the rubber core, reducing various transverse force between the vehicle frame and the balance suspending frame, and improving vehicle running stability.
Description
Affiliated technical field
Technical field described in the utility model is a kind of equalizing suspension system member, relates in particular to the torsion glue core that a kind of equalizing suspension system of truck is used.
Background technique
As Fig. 1, in order to make doube bridge truck automobile balance suspension that good performance be arranged, equalizing suspension system adopts back reaction rod torsion glue core assembly 2, back axle 3,4 is connected with vehicle frame 1 in making, when equalizing type of suspension moves up and down, back reaction rod two ends torsion glue core assembly 5 is stressed and produce resiliently deformable, reduce the vibration and the external force of wheel and disturb, play buffer function, to reach the stability of vehicle driving.
Tradition torsion glue core 5 ' as shown in Figure 2, axis 51 ' is a cylindrical body, can only move horizontally.Reduce buffering, when the road surface bad, middle back axle double swerve, when producing skew force, axis 51 ' can't be swung and cause lateral stressed excessively, makes glue core 52 ' produce disconnected glue, come unstuck, and influences glue core working life.Buffer function is not obvious can't to guarantee riding stability.
Summary of the invention
The utility model provides a kind of truck with torsion glue core, and its advantage axis can turn to swing, and it is directly stressed to reduce the glue core, prolongs glue core working life, reduces various transverse forces between vehicle frame and the equalizing type of suspension, improves vehicle run stability.
Technical solutions of the utility model are:
A kind of truck torsion glue core, comprise axis, the lasso that middle outer shaft sleeve is established, lasso is by outer ring, elastomer, inner ring be combined in turn, it is characterized in that: axis middle part convex spherical in shape, described hemisphere jut external diameter cooperates sheathed with described inner ring, the hemisphere jut both sides are provided with the bowl-shape elastomer that closely cooperates and be provided with described inner ring and described axis.
Bowl-shape elastomer both sides also are provided with and the described inner ring sheathed back-up ring that closely cooperates, and are provided with the elastic buffer circle between back-up ring and the axis.

Embodiment
The utility model preferred embodiment as shown in Figure 3, comprise axis 51, axis 51 outer sheathed lassos, lasso is by outer ring 53, gelatinous elastomer 52 (being the glue core), inner ring 54 be combined in turn, as Fig. 4, axis 51 middle parts 511 convex spherical in shape, described hemisphere jut 511 external diameters cooperate sheathed with described inner ring 54, hemisphere jut 511 both sides are provided with the bowl-shape elastomer 55 of colloid that closely cooperates and be provided with described inner ring 54 and described axis 51, and the bowl-shape elastomer 55 of colloid as shown in Figure 5.
Bowl-shape elastomer 55 both sides also are provided with and the described inner ring 54 sheathed back-up ring 56 that closely cooperates, and are provided with elastic caoutchouc buffer ring 57 between back-up ring 56 and the axis.Back-up ring 56 and buffer ring 57 can prevent that bowl-shape elastomer 55 from laterally coming off.
When equalizing type of suspension moved up and down, it is stressed that the bowl-shape elastomer 55 of the hemisphere jut 511 both sides colloids at torsion glue core axis 51 middle parts absorbs part vibration earlier, and remaining various vibration forces are transmitted by described gelatinous elastomer 52 and absorb; When the road surface bad, middle back axle 3,4 rocks the generation skew force up and down, spherical axis can turn to swing, and it is directly stressed to reduce gelatinous elastomer 52, prolongs glue core working life, reduce various transverse forces between vehicle frame and the equalizing type of suspension, avoid the tire premature damage, buffer function is quite obvious, improves vehicle run stability.
Claims (2)
1, a kind of truck torsion glue core, comprise axis, the lasso that middle outer shaft sleeve is established, lasso is by outer ring, elastomer, inner ring be combined in turn, it is characterized in that: axis middle part convex spherical in shape, described hemisphere jut external diameter cooperates sheathed with described inner ring, the hemisphere jut both sides are provided with the bowl-shape elastomer that closely cooperates and be provided with described inner ring and described axis.
2, a kind of truck as claimed in claim 1 is characterized in that with torsion glue core: bowl-shape elastomer both sides are provided with and the described inner ring sheathed back-up ring that closely cooperates, and are provided with the elastic buffer circle between back-up ring and the axis.
