Detailed Description
The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.
It should be noted that, in the description of the present invention, the directions or positional relationships indicated are the directions or positional relationships shown in the drawings, which are only for convenience of description and simplification of description, and the indication or suggestion that the indicated device or element must have a specific direction, be constructed and operated in a specific direction is not understood as a limitation of the present invention.
As shown in fig. 1, the utility model provides a many damping element of wide body tipper front suspension, first damping element and second damping element including the interval setting, wherein:
the first damping element comprises a first fixing support 1, a first shock absorber 2, a positioning support 3 and a first limiting block 4, the upper end of the first shock absorber 2 is connected with the first fixing support 1, the positioning support 3 is arranged below the first fixing support 1 and has a distance with the first fixing support 1, and the first limiting block 4 is fixed at the lower end of the positioning support 3;
the second damping element comprises a second fixing bracket 7, a second shock absorber 8 and a second limiting block 9, the upper end of the second shock absorber 8 is connected with the second fixing bracket 7, and the second limiting block 9 is fixed at the lower end of the second fixing bracket 7;
the first fixing support 1, the positioning support 3 and the second fixing support 7 are all arranged on the frame, and the lower ends of the first shock absorber 2 and the second shock absorber 8 are connected with the steel plate spring 6.
In the technical scheme, when the off-highway wide dumper drives an axle to jump upwards due to wheels on an uneven road, the steel plate spring 6 of a front suspension is arched upwards, meanwhile, the lower end of the first shock absorber 2 and the lower end of the second shock absorber 8 move upwards, the deformation of the steel plate spring 6 has a buffering effect on the upward impact force of the axle, the vibration is attenuated, the first shock absorber 2 and the second shock absorber 8 are in a compressed state due to the fact that the upper ends of the first shock absorber 2 and the second shock absorber 8 are fixed and the lower ends of the first shock absorber and the second shock absorber move upwards, the vibration is increased, the vibration can be effectively attenuated, the two shock absorbers arranged at intervals can balance and buffer the upward impact force, the smoothness of the whole dumper is obviously improved, the impact force borne by the steel plate spring 6 is also reduced, when the vibration amplitude is too large, the steel plate spring 6 further arches upwards, when the distance between the first limiting block 4 and the steel plate spring 6 is smaller than the distance, first stopper 4 plays buffering and spacing effect, and leaf spring 6 further contacts with second stopper 9, and leaf spring 6's impact force can be shared to two stoppers, and protection leaf spring 6 does not take place plastic deformation and fracture, prolongs the life of spare part, improves whole car travelling comfort simultaneously. When the wheels drive the axle to jump downwards, the first shock absorber 2 and the second shock absorber 8 are in a stretching state, and downward impact force can be balanced and vibration can be effectively attenuated. Therefore, the first damping elements and the second damping elements are arranged on the front suspension at intervals, impact force can be balanced, excessive vibration is effectively attenuated, the comfort of the whole vehicle is improved, the running vehicle speed is guaranteed, the transportation capacity is enhanced, and the service life of parts is prolonged.
In another technical scheme, the first damper 2 and the first fixing support 1, the second damper 8 and the second fixing support 7, the first limiting block 4 and the positioning support 3, the second limiting block 9 and the second fixing support 7 are all fixed by bolts, so that the connection is stable, and the disassembly and the assembly are convenient.
In another technical scheme, the positioning bracket 3 is arranged right below the first fixing bracket 1, so that the first limiting block 4 is positioned right behind the first shock absorber 2, and the vibration attenuation effect of the first damping element can be effectively enhanced.
In another technical scheme, the first fixing support 1, the positioning support 3 and the second fixing support 7 are all fixed on the frame by bolts, so that the fixing is firm, and the installation is simple and convenient.
In another technical scheme, the length of the steel plate at the lowermost end of the leaf spring 6 is shortest, and two ends of the steel plate are both in a double-rolling-lug structure, so that the first damping element, the first damping element and the leaf spring 6 are conveniently connected.
In another kind of technical scheme, the lower extreme of first bumper shock absorber 2 the lower extreme of second bumper shock absorber 8 respectively through down the yoke 5 with leaf spring 6 connects, a pair of yoke 5 down with leaf spring 6's two reel ear structures adopt the hub connection, and the contained angle between first bumper shock absorber 2, second bumper shock absorber 8 and the leaf spring 6 passes through the hub connection adjustment, effectively alleviates the loss of spare part, increase of service life to improve whole car travelling comfort.
