Description
Technical field
The present invention relates to a kind of endless track installation, particularly a kind of low formula endless track installation of putting of band suspension shock absorption device of crawler type glide steering loader.
Background technology
The endless track installation of crawler type glide steering loader is divided into high-position placed endless track installation and low two kinds of the formula endless track installations of putting according to the deployment scenarios of drive wheel at present.Low put the formula endless track installation and have the high characteristics of the big reliable transmission property in drive wheel envelope angle, but the shortcoming that also exists the compact miscellaneous part of structure space to be difficult to arrange.Because low inner space compactness of putting the formula endless track installation; Complicated suspension shock absorption device can't arrange, is to be rigidly connected between the therefore traditional low caterpillar wheel of putting the formula endless track installation and the stand, and vehicle is worked on the ground of injustice or during the vehicle throwing over barrier; Can cause the weight of bearing complete machine by few part caterpillar wheel; Can produce violent vibrations and impact during walking, influence the service life of vehicle part and the traveling comfort of driving, also reduce greatly the service life of caterpillar wheel itself.Because track area reduces, and the crawler belt earth-grasping force reduces, cause tractive force to reduce simultaneously; And, be prone to produce the danger of crawler belt derailing in the walking process because part caterpillar wheel and chain rail are separated.
Chinese patent ZL200720157409.x discloses a kind of tracklaying vehicle caterpillar wheel suspension gear; This caterpillar wheel suspension gear adopts X type cross-articulation structure; Rubber absorbers are installed between crossover location; Therefore the swing of this suspension gear receives the obstruction of rubber absorbers when running into obstacle, has influenced the caterpillar wheel obstacle climbing ability greatly.
Summary of the invention
Goal of the invention: the purpose of this invention is to provide a kind of low formula endless track installation of putting that not only can realize cushioning effect but also not influence the band suspension shock absorption device of caterpillar wheel obstacle climbing ability.
Technical scheme: a kind of low formula endless track installation of putting with the suspension shock absorption device; Comprise drive wheel, tensioning wheel assembly, stand, caterpillar wheel and crawler belt; Low put the formula endless track installation and be fixed on the vehicle frame both sides through stand; Said tensioning wheel assembly comprises tension wheel and tensioning spring, and tension wheel is through the flexible connection of tensioning spring and stand, is connected through the suspension shock absorption device between said caterpillar wheel and the stand; Said suspension shock absorption device comprises cushion blocking and link span; Said link span comprises hinge, swivel pin and support; Said support comprises two side plates, crossbeam and hinge eyes, and said two blocks of side plates and crossbeam are fixedly connected to form H shape structure, and said hinge eyes is fixed on the crossbeam in the middle of the H shape structure; The indentation, there at H shape structure two ends is hinged with caterpillar wheel respectively; Swivel pin passes the through hole of the hinge eyes on hinge and the support and realizes the hinged of hinge and support.Caterpillar wheel itself can freely swing, and does not receive the influence of miscellaneous part in allowed limits; Caterpillar wheel wheel body when running into obstacle can freely swing along with the shape of obstacle in the process that caterpillar wheel breaks the barriers along with support is swung around swivel pin together, has improved the ability of the clear an obstacle of caterpillar wheel greatly.
The side of said stand is provided with the limiting stopper of the pendulum angle of the support that limits caterpillar wheel.Pendulum angle is controlled by limiting stopper, therefore can adjust the shape and the installation site of limiting stopper and adjust pendulum angle; Interfere with stand in swing process for fear of caterpillar wheel, the pendulum angle of limiting stopper limit bracket is installed in the side of stand.
In order to improve the damping effect of suspension shock absorption device, said suspension shock absorption device is provided with on four corners that four cushion blockings are positioned at hinge.Impulsive force can be born by four cushion blockings jointly, but also can adapt to the side on oscillation or the further obstacle climbing ability that improves caterpillar wheel of caterpillar wheel through two cushion blockings of compression the same side.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: 1, the caterpillar wheel pendulum angle is big, and obstacle climbing ability is strong; 2, good damping effect; 3, simple and compact for structure, low cost of manufacture.
