Abstract
The utility model relates to a hanging and shock absorbing device for a crawler, which is composed of a rotary shaft, a supporting frame, a shock absorber, a pin shaft, thrust wheels and a swing frame, wherein the two thrust wheels are hinged on the swing frame; the middle part of the swing frame is hinged on the supporting frame through the pin shaft; a rubber shock absorber is arranged on the supporting frame, and the rotary shaft which is hinged with a machine frame is arranged at the front part of the supporting frame. The utility model can ensure the matching and the control of the thrust wheels and a crawler chain, and can prolong the service life of a running system. When the utility model runs on an uneven terrain, large traction force can be obtained because the thrust wheels and the crawler chain always contact, the effective grounding length of the crawler is not changed, and the sliding amount of the crawler is reduced; simultaneously, good equilibrium performance of the hanging and shock absorbing device can be ensured because vibration is reduced. In addition, the comfort of driving is improved. The hanging and shock absorbing device can be used for various crawler type engineering machines.
Description
Technical field:
The utility model relates to a kind of crawler belt suspended shock damper of tracklaying vehicle, is used for vehicle is supported on crawler belt.
Background technology:
Tradition caterpillar machinery machine frame system mainly is made up of frame and " four-wheel one band ", and wherein caterpillar wheel is connected with rigidity of frame, and machinery weight is passed to ground by caterpillar wheel.During work, as the ground injustice, caterpillar wheel can partly break away from crawler belt, thereby caterpillar wheel will often be impacted, so the suffered load of caterpillar wheel is bigger, has also increased the impact load to the running gear parts simultaneously.
Summary of the invention:
The purpose of this utility model provides a kind of crawler belt suspended shock damper, overcome original caterpillar machinery machine frame system damping performance defect of bad, improve damping property, impact and vibrations when reducing vehicle ', prolong the service life of vehicle to run system unit, improve the traveling comfort of driving.
The purpose of this utility model realizes as follows: this crawler belt suspended shock damper also relates to caterpillar wheel and support, two caterpillar wheels are hinged on the rocker, rocker is hinged on the support by bearing pin, and bumper is housed above the support, is equipped with in the front portion of support and frame pivotally attached turning cylinder.Whole suspended shock damper has two swing fulcrums: caterpillar wheel can be around rocker bearing pin swing, the support moving axis swing that can rotate.Vehicle is in when work, if there is recess on ground, the support moving axis that can rotate makes caterpillar wheel sagging to lower swing, and caterpillar wheel is contacted with caterpillar chain all the time; If run into obstacle, support can rotate moving axis upwards swing and making put on the caterpillar wheel, bumper is at first contacted with frame, reduced vibrations.Because the moving displacement of caterpillar wheel increases greatly, and caterpillar wheel is contacted with crawler belt all the time, has significantly reduced the impact load to the running gear parts.
Bumper is rubber absorbers, and is simple and reliable for structure.
This crawler belt suspended shock damper can guarantee the control that cooperates of caterpillar wheel and caterpillar chain, the life-span of having improved running gear.When rugged landform is travelled, because caterpillar wheel contacts all the time with caterpillar chain, crawler belt actv. ground contact length is constant, the slippage of crawler belt reduces, and can obtain bigger tractive force, simultaneously owing to vibrations reduce, also guarantee the balance that machine is fabulous, improved the traveling comfort of driving.This device can be widely used in various tracked construction equipments.
Description of drawings:
Accompanying drawing is the structural representation of the utility model crawler belt suspended shock damper.
The specific embodiment:
With reference to accompanying drawing, this crawler belt suspended shock damper is made of turning cylinder 1, support 2, bumper 3, bearing pin 4, caterpillar wheel 5 and rocker 6, two caterpillar wheels 5 are hinged on the rocker 6, rocker 6 middle parts are hinged on the support 2 by bearing pin 4, rubber absorbers 3 are housed above the support 2, be equipped with and frame pivotally attached turning cylinder 1 in the front portion of support 2, caterpillar wheel 5 can be around the bearing pin on the rocker 6 swing, support 2 moving axis 1 swing that can rotate.
