Description
Technical field
The present invention relates to a kind of farm tractor articulated steering mechanism.
Background technology
At present, agricultural miniature trac. is very extensive in the application of rural area, small towns, and common type is bowing, and the main traffic instrument as rural area goods transport causes the concern of more and more people.Bowing compact tractor turns to different from general-utility car, mechanism of bowing mainly by connecting front vehicle frame and Rear frame realizes turning to, the road surface that trac. travels is comparatively complicated, rugged and rough, general bow-type tractor steering hardware can only left and right turn, can not rotate in vertical direction, two front-wheels can not road pavement height change adjust in time, axis of traction is made to bear larger twist moment, add trac. front vehicle frame to upwarp, steering hardware deforms, and the resistance turned to is increased, turn to effort, parts depreciation is accelerated.
Summary of the invention
Technical matters to be solved by this invention is, for the defect that above-mentioned prior art exists, a kind of farm tractor articulated steering mechanism is provided, trac. head can not only be rotated in the horizontal direction, and can realize in vertical direction rotating, and enabling for two front-wheel moment adapt to the change of floor level, close proximity to ground, earth-grasping force is strong.
It is as follows that the present invention solves the problems of the technologies described above taked technical scheme:
A kind of farm tractor articulated steering mechanism, comprises towing pin, towing pin upper mounted plate, towing pin bottom plate, towing pin capping, positioning plate, banking pin, axis of traction, traction axle sleeve, traction axle sleeve front shoe, traction axle sleeve rear fixed plate and axis of traction nut; Described axis of traction one end is provided with draw pin openings, towing pin is through draw pin openings and be vertically mounted on two towing pin cappings, the axis of towing pin and the axes normal of axis of traction, two towing pin cappings are arranged on towing pin upper mounted plate and towing pin bottom plate respectively; Axis of traction freely can rotate in the horizontal direction around towing pin, the axis of traction other end is through traction axle sleeve, traction axle sleeve two ends are arranged on traction axle sleeve front shoe and traction axle sleeve rear fixed plate, and the two ends, left and right of traction axle sleeve front shoe and traction axle sleeve rear fixed plate are separately fixed on rear frame of vehicle beam; Axis of traction is through the end axis of traction nut screwing clamping of traction axle sleeve, and prevent axis of traction vibration vertically, axis of traction can rotate in vertical direction around own axes, the inclination angle on adjustment front vehicle frame and ground; Positioning plate is arranged on the both sides of axis of traction front end, and banking pin to be arranged on traction axle sleeve front shoe and corresponding with positioning plate, for limiting the hard-over of axis of traction and preventing axis of traction and positioning plate from colliding.
Between described towing pin upper mounted plate and towing pin bottom plate, vertical baffle is installed, between towing pin upper mounted plate and vertical baffle, is provided with cushion block, towing pin upper mounted plate and level ground shape are had angle, towing pin and ground out of plumb.
The angle that described towing pin upper mounted plate and level ground are formed is 1.5 degree.
Also be fixed with axis of traction cover plate above and below described axis of traction cover, axis of traction cover plate is fixed on rear frame of vehicle beam.
The beneficial effect that the present invention possesses is: axis of traction can rotate to an angle in vertical direction around own axes in traction axle sleeve, thus the angle on adjustment front vehicle frame and ground, two front-wheels are made to adapt to the change of floor level, moment ensures that wheel can close proximity to ground, also plays the effect of damping simultaneously.Structure of the present invention is simple, and structural rigidity is good, not easily deforms, and little to the wearing and tearing of axis of traction and towing pin, steering effort is little.
Instant invention overcomes common tractor steering angle little, turn to effort, the problem that two front-wheels can not adjust in time to floor level, improve the comformability of front-wheel road pavement on the one hand, make the earth-grasping force of trac. better, reduce the twist moment that axis of traction is subject on the other hand, articulated steering mechanism is out of shape little, cornering resistance is little.
