Abstract

The utility model relates to a frame connecting device for a crawler tractor. The frame connecting device for the crawler tractor comprises connecting rack dampers, connecting rack base dampers, connecting beams, connecting rack bases, washers, bolts and connecting racks, wherein the two connecting rack bases and the two connecting racks are symmetrically connected onto the connecting beams through the washers and the bolts, and the connecting racks are arranged above the connecting beams; the connecting rack bases are arranged below the connecting beams, and the connecting rack dampers are adhered onto the connecting racks; the connecting rack base dampers are adhered onto the connecting rack bases, and the washers and the bolts are arranged on the connecting racks; and the two ends of the connecting beams are provided with flange connecting surfaces, and the connecting rack dampers and the connecting rack base dampers are in a semi-circular shape. Compared with the conventional structure, the frame connecting device has the advantages that the two semi-circular rubber dampers are used, so that the device has a multi-directional damping function; and meanwhile, the rubber has compressibility, so that the processing precision requirements of the related connecting pieces are low, and the processing cost is reduced.

Description

The crawler-tread tractor frame connecting device
Technical field
The utility model belongs to the trac. field, relates to a kind of crawler-tread tractor frame connecting device .
Background technology
At present, the body of crawler-tread tractor roughly has two kinds of modes with being connected of vehicle frame, and a kind of is to be rigidly connected, and its connection mode is: between vehicle frame and body, by equalizing bar, be connected, that is: between equalizing bar and vehicle frame and body, all be bolted, all connections are all rigidity; Another kind is semi-rigid connection, that is: between equalizing bar and body for being rigidly connected, be provided with rubber absorbers on the vertical direction between equalizing bar and vehicle frame.Because crawler-tread tractor vibrates greatlyr under steam, and direction of vibration is different, so these two kinds of connection modes all can not effectively reduce the vibration of trac..Therefore, develop a kind of novel vehicle frame and body connecting device, realize that crawler-tread tractor, in the damping effectively of horizontal and vertical direction, will be subject to user's favor.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, easy installation and reliable, the crawler-tread tractor frame connecting device that can realize the multiple directions damping.
The technical solution of the utility model is: the crawler-tread tractor frame connecting device comprises: link span bumper, link span base bumper, tie-beam, link span base, packing ring, bolt, link span; It is characterized in that: two link span bases and two link spans are connected on tie-beam by packing ring, bolt symmetry respectively, and link span is above tie-beam, and the link span base is below tie-beam; The link span bumper is bonded on link span, and link span base bumper is bonded on the link span base.
Be provided with packing ring and bolt on link span, on tie-beam, two ends are with flange connection surface.
Link span bumper and link span base bumper are semicircle.
The utility model can reach following beneficial effect after adopting technique scheme: compare with conventional structure, owing to having adopted two semi-round rubber absorbers, make whole device have multi-aspect shock-absorbing function; Due to the compressibility of rubber, make the requirement on machining accuracy of related fittings lower simultaneously, reduced tooling cost.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model crawler-tread tractor with frame connecting device;
Fig. 2 is the A-A structure cutaway view of utility model crawler-tread tractor with frame connecting device.
The specific embodiment
Shown in Fig. 1 and Fig. 2, the crawler-tread tractor frame connecting device comprises: link span bumper 1, link span base bumper 2, tie-beam 3, link span base 4, packing ring 5, bolt 6, link span 7.Link span bumper 1 is bonded on link span 7, and link span base bumper 2 is bonded on link span base 4, and two link span bases 4 and two link spans 7 are connected on tie-beam 3 by packing ring 5, bolt 6 respectively; Link span 7 is above tie-beam 3, and link span base 4 is below tie-beam 2; Two link span bases 4 symmetrical installation on tie-beam 3; Two link spans 7 symmetrical installation on bracing beam 3.
Semi-round link span base 4 and semi-round link span bumper 1 bond together, and semi-round link span 7 and semi-round link span base bumper 2 bond together, and are arranged on circular tie-beam 3 simultaneously.Trac. produces severe jolt under steam, vibration is delivered on link span bumper 1 and link span base bumper 2 by tie-beam 3, link span bumper 1 and link span base bumper 2 produce distortion, deformation energy is because the damping capacity of rubber consumes, thereby realize damping having reduced noise simultaneously; Because link span bumper 1 and link span base bumper 2 annulars wrap in around tie-beam 3, make whole device all there is shock-absorbing function on all directions longitudinally.
Tie-beam 3 is when connecting vehicle frame and body, because related fittings is many, only guaranteed higher working accuracy just can make the correlated parts exact connect ion, the utility model has been used link span bumper 1 and link span base bumper 2 as attaching parts, because rubber has compressibility, scale error is had to certain compensating action, so the requirement on machining accuracy of related fittings is lower, thereby has reduced tooling cost.
