CN103202120A discloses a kind of draw gear of Multipurpose field operation machine on July 17th, 2013, it arranges surface bearing at the lower surface place that traction box and axis of traction directly contact, and copper sheathing is set on traction stub, although this device can reduce stub distortion to a certain extent, stub weares and teares and the wearing and tearing of traction box, but or not ideal enough, in addition, this device is reasonable not enough in space layout, the bearing capacity born is limited, and stability has much room for improvement.
Summary of the invention
Technical matters to be solved by this invention is, provide a kind of wearing and tearing that not only can reduce stub distortion, stub wearing and tearing, traction box, and space layout is reasonable, load-carrying capacity is strong, the draw gear of the Cross-country tractor that stability is high.
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, first traction stub, 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 connector I, bottom is provided with a pair connector II, described connector I, stub mounting hole is respectively equipped with in connector II, the centre of described traction box is provided with the hole for installing rear drive shaft, described axis of traction fixed bin is welded on the left-right longeron of Rear frame, described axis of traction is equipped with axle sleeve, 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, connecting bore is respectively equipped with in left engaging lug and right engaging lug, 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 first traction stub, the upper and lower side of the second traction stub all has groove, blocked by the opening of locking plate, 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 lower surface place that axis of traction contacts with traction box.
Further, described upper engaging lug and first draws between stub and is provided with the first copper sheathing, and described lower engaging lug and second draws between stub and is provided with the second copper sheathing.
Compared with prior art, the present invention has the following advantages:
(1) axis of traction draws stub with traction box by two and is connected, can better ensure traction box and axis of traction assemble after resistance to overturning, load-carrying capacity is strong;
(2) by arranging locking plate, effectively can prevent from drawing the relative motion of stub in axial direction and radial direction, ensureing that whole draw gear rotates more steadily safety;
(3) axis of traction is arranged two engaging lugs in left and right, one is connected with drag link, and it two is connected with steering cylinder, can ensure complete machine turning function, and space connection and reasonable arrangement;
(4) traction box is provided with hole for installing rear drive shaft and axis of traction is hollow shaft, is skillfully constructed, compact conformation;
(5) wear-resisting plain cushion area of contact is large, bearing pressure is large, not only effectively can regulate the gap between axis of traction and traction box, also can ensure relatively rotating of axis of traction and traction box, effectively can reduce skimming wear when relatively rotating simultaneously, ensure that it rotates more steadily safety.
Further, upper engaging lug and first draws between stub and arranges the first copper sheathing, and lower engaging lug and second draws between stub and arranges the second copper sheathing, effectively can prevent the wearing and tearing of axis of traction, also largely reduce the wearing and tearing of traction stub, thus improve the service life of axis of traction, traction stub.
