Description

Vehicle drawing seat

The utility model relates to a kind of heavy loading wheel tractor and is used for the improvement of drawing piece structure of tractive superimposed trailer, belongs to field of automobile, is a kind of vehicle traction seat specifically.

The situation of vehicle traction seat is at present, and a kind of flap plate adopts steel casting, and another kind of flap plate adopts steel plate compression moulding.Adopt the flap plate structure of steel casting, required complex process, casting quality is difficult to control, so qualification rate is low, the cost of product height; Weight is big, and single-piece weight ratio steel plate rolled-up stock is heavy 70～90 kilograms, has reduced the automobile cargo capacity.Another kind of vehicle traction flap plate with steel plate compression moulding, the supporting gusset position of weld below it is too concentrated, easily causes the distortion of welding deformation and unbalance stress; General nothing has lubricating system, has only individual component that oil hole is arranged, but adds the oiling inconvenience, causes long-time oil starvation that the traction seat wedge is caused rapid wear.

The utility model purpose is to overcome the shortcoming in the above-mentioned technology, a kind of vehicle traction seat of structural development is proposed, improve the shape and the structure of adjustment disk in its flap plate and the tight mechanism of rope, increase lubricating pipe, to improve stability, rigidity, resistance to abrasion and the reliability of vehicle traction seat.

Goal of the invention of the present utility model can realize with following technical scheme: this is used for the vehicle traction seat of tractive superimposed trailer, respectively there is a saddle base both sides below the flap plate that is pressed into steel plate, connect with the flap plate with bearing pin, the saddle base rotates before and after the flap plate can be the center with the bearing pin, the bottom surface of saddle base connects with the automobile of tractive with screw, the liner rubber coating produces 1100 Ns/rice moment of torsion, flap plate below is provided with one by horseshoe, wedge, the hook tongue, adjustment disk, cross bar, pull bar, the tight mechanism of rope that spring is formed, horseshoe is fixed on the flap plate, with bearing pin butt hook tongue, pull bar and cross bar, wedge also connects with bearing pin, and pull bar is connected on the gusset below the cover plate by spring.Two afterbodys of shape of a saddle flap plate back are great circle arcs, and there is the concave surface of a butterfly shape at the middle part, and whole plane is divided into the close part of 5 block sizes.The shape of two sides of flap plate is middle part broad, narrower streamline contours in both sides, is welded with the groined type reinforced rib below the flap plate, also is provided with a cover lubricating pipe under the flap plate.

Flap plate profile adopts great circle arc, two afterbody large circular arc radius of back are 126～130 millimeters, the butterfly shape concave surface recessed degree of depth in middle part is 4～6 millimeters, the concave surface of butterfly shape is divided into the close part of size with the flap board plane, be welded with the groined type reinforced rib of wider distribution below the flap plate, the improvement of these structures, improved the mechanical strength of flap plate, stability and rigidity have been increased, its surperficial planeness meets international standards, out-of-flat is less than 1.25 millimeters, and the structure out-of-flat before improving reaches 5 millimeters.Two side edge shape of flap plate are middle part broad, the narrower streamline contour in both sides, and the shape smoothness is attractive in appearance like this, has also increased the inclined back and forth angle.The reinforced rib of groined type is an integral body below the flap plate, generally is after being welded into a single-piece groined type reinforced rib earlier, to be welded in below the flap plate again.

In the tight mechanism of rope that forms by horseshoe, wedge, hook tongue, adjustment disk, cross bar, pull bar, spring, adjustment disk is an eccentric disc, on eccentric orfice, be connected with wedge with bearing pin, be the center with the eccentric orfice, to be 5 apertures that are used for regulating the wedge position of distribution equidistant on the circular arc of radius greater than disc radius, less than the length of disk diameter, be used for regulating the position of wedge and wedge fixed.Because the vehicle traction seat in the course of the work, because can producing wearing and tearing, use causes the gap between wedge and the hook tongue, therefore to regulate the position of wedge, make the gap can not be excessive, can guarantee to be on the correct position between trussed shore on the superimposed trailer and the vehicle traction seat, make that the vehicle traction seat turns to flexibly, supporting ﹠ stablizing when the tractive superimposed trailer.

The vehicle traction seat is that the superimposed trailer that is pulled connects traction and turns to usefulness with trailer, needs lubricating system.Lubricating pipe of the present utility model has 4 oil to chew to be connected as one, coexist on the side of cover plate seat with the handgrip of pull bar, chewed by 4 oil and draw 4 oil pipe lines, 1 leads to hook tongue and horseshoe, article 1, lead to wedge, other 2 pipelines lead to the diverse location of flap plate respectively.Chew inside oiling by 4 oil, by 4 pipelines oil is transported to diverse location and lubricates, reduced friction and wear between flap plate and the superimposed trailer, reduced noise, make contact surface keep optimum Working and reliability.Because oil is chewed the same side that is placed on the pull bar handgrip, and is easy to operate.

The utility model advantage is because structure, the shape of some vital partss in the vehicle traction seat have been done improvement, increased lubricating pipe again, improve the mechanical strength of vehicle traction seat, also improved stability, rigidity, resistance to abrasion and reliability, prolonged service life.

Embodiment of accompanying drawings:

Fig. 1 is a vehicle traction seat front view,

Fig. 2 is a vehicle traction seat birds-eye view,

Fig. 3 be vehicle traction seat A to view,
