Abstract
The utility model discloses a bogie suspender for caterpillar tractor, which mainly comprises four thrust wheels, a big balance arm and a small balance arm. The big and the small balance arms are connected with each other by an oscillating shaft, two springs which are sheathed together and have opposite rotation directions are arranged between the big and the small balance arms, and the thrust wheels are assembled on the balance arms by wheel shafts. The whole suspender is assembled on a bogie shaft by a locking bolt, and the diameter of the thrust wheel, the thickness of the wheel edge and the margin of the wheel edge are enlarged meanwhile. A sealing device of the thrust wheel and the balance arm is provided with a sealing lip which is provided with an annular convex edge. The utility model has the advantages of good sealing performance, reasonable structure and reliable strength, and the service performance of the whole suspender can be improved further.
Description
The utility model belongs to general agricultural mechanical field, relates to a kind of crawler-tread tractor bogie suspension device that is applicable to.
At present, the crawler-tread tractor that in the Tendency of Agricultural Machinery in China field, uses, its bogie suspension device mainly comprises: four caterpillar wheels and big or small two equilibrium arms and two opposite pocketed springs of rotation direction of size.Caterpillar wheel and caterpillar wheel shaft seal only seal for the side seal band that large and small seal ring forms; Its chassis shaft locking device is also only fixed by three lock screws; The edge of its caterpillar wheel is also thiner.This draft hitch in use can occur poorly sealed, and screw pine, disconnected occurs because of unbalance stress, and the caterpillar wheel edge is prone to phenomenons such as early stage crimping.
The purpose of this utility model is to provide a kind of good seal, rational in infrastructure, intensity failure-free crawler-tread tractor bogie suspension device.
The utility model adopts following technical scheme to realize above-mentioned purpose: described device has four caterpillar wheels, large and small equilibrium arm, large and small equilibrium arm connects with an oscillating axle, two opposite pocketed springs of rotation direction are housed between large and small equilibrium arm, caterpillar wheel is assembled on the equilibrium arm by wheel shaft, whole draft hitch is by whole being assembled on the chassis axle of lock bolt, the outside diameter of each caterpillar wheel be 350mm (± 2mm), flange thickness is 20mm, wheel rim hem width 48mm, the sealing arrangement of caterpillar wheel and equilibrium arm one have the sealing lip of cyclic convex edge.
The utility model can reach following good effect, because the sealing lip that increased frame has further improved sealing effectiveness, thickening caterpillar wheel wheel rim increases the caterpillar wheel depth of hardening with the mid frequency induction hardening new process, has overcome the early stage edge-curl phenomenon of wheel rim.Change three lock screws into a lock bolt, bolt strength increases, and has stressedly evenly overcome and has damaged a screw in the original design and influence whole latching device unbalance stress phenomenon, has further improved the in-use performance of whole suspension system.
Below in conjunction with embodiment the utility model is further described:
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model part sectional view.
Bogie suspension device as shown in FIG. comprises compositions such as caterpillar wheel 1, little equilibrium arm 2, big damper spring 3, little damper spring 4, big equilibrium arm 5, supporting wheel shaft 6, lock bolt 7, oscillating axle 8, the little axle sleeve 9 of equilibrium arm, equilibrium arm large shaft sleeve 10, sealing lip 11.
Illustrate that with reference to the accompanying drawings working process of the present utility model is as follows:
Trac. is when normal operation, and the caterpillar wheel 1 of its draft hitch rotates around wheel shaft 6, as uneven ground or when being subjected to impacting, caterpillar wheel 1 by big equilibrium arm 5, little equilibrium arm 2 compresses big springs 3 and little spring 4 plays damping of vibrations.Little equilibrium arm 2 can rotate around oscillating axle 8, and big equilibrium arm 5 can rotate around the line of centers of bolt 7, i.e. chassis axle 5 on the support.The little axle sleeve 9 of equilibrium arm is used for reducing the wearing and tearing of oscillating axle 8, takes place if any wear pattern in the use, can only change little axle sleeve 9.The effect of equilibrium arm large shaft sleeve 10 reduces the wearing and tearing of vehicle frame chassis axle, only needs to change large shaft sleeve if any wearing and tearing in the use.11 of sealing lips are in order to increase the side seal effect.
