The technical solution adopted for the present invention to solve the technical problems is: a kind of draw gear of cross-country tractor, comprise traction box, axis of traction, axis of traction fixed bin, the first traction stub, the second traction stub, wear-resisting plain cushion, locking plate and axis of traction captive nut, described traction box is welded on the left-right longeron of front vehicle frame, the upper rear end of described traction box is provided with a pair of connector I, bottom is provided with a pair of connector II, described connector I, in connector II, be respectively equipped with stub mounting hole, the centre of described traction box is provided with the hole for rear drive shaft is installed, described axis of traction fixed bin is welded on the left-right longeron of rear vehicle frame, on described axis of traction, axle sleeve is housed, described axis of traction is arranged in axis of traction fixed bin, fastening by axis of traction captive nut, described axis of traction is hollow shaft, the front end of described axis of traction is respectively equipped with engaging lug, lower engaging lug, left engaging lug and right engaging lug, described upper engaging lug, lower engaging lug, in left engaging lug and right engaging lug, be respectively equipped with connecting bore, described upper engaging lug is connected with the connector I in traction box by the first traction stub, described lower engaging lug is connected with the connector II in traction box by the second traction stub, described the first traction stub, the upper and lower side of the second traction stub all has groove, opening by locking plate blocks, described locking plate is fixed in traction box by nut, described left engaging lug is connected with the drag link of hydraguide, described right engaging lug is connected with the steering cylinder of hydraguide, described wear-resisting plain cushion is arranged on the place, lower surface that axis of traction contacts with traction box.
Further, between described upper engaging lug and the first traction stub, be provided with the first copper sheathing, between described lower engaging lug and the second traction stub, be provided with the second copper sheathing.
Compared with prior art, the present invention has the following advantages:
(1) axis of traction is connected by two traction stubs with traction box, can better guarantee the resistance to overturning after traction box and axis of traction assembling, and load-carrying capacity is strong;
(2) by locking plate is set, can effectively prevent from drawing the relative motion of stub in axial direction and radial direction, ensure that whole draw gear rotates more steadily safety;
(3) two engaging lugs in left and right are set on axis of traction, one is connected with drag link, and it two is connected with steering cylinder, can guarantee complete machine turning function, and space connection and reasonable arrangement;
(4) to be provided with hole and axis of traction for rear drive shaft is installed be hollow shaft to traction box, be skillfully constructed, and compact conformation;
(5) wear-resisting plain cushion area of contact is large, bearing pressure is large, not only can effectively regulate the gap between axis of traction and traction box, also can guarantee relatively rotating of axis of traction and traction box, can effectively reduce the skimming wear while relatively rotating, ensure that it rotates more steadily safety simultaneously.
Further, between upper engaging lug and the first traction stub, the first copper sheathing is set, between lower engaging lug and the second traction stub, the second copper sheathing is set, can effectively prevent the wearing and tearing of axis of traction, also largely reduce the wearing and tearing of traction stub, thereby improve the service life of axis of traction, traction stub.
