Abstract
The utility model discloses a drawing saddle for a semi-pulling type vehicle used for the connection of a main vehicle and a trailer, which belongs to one component of a semi-pulling type vehicle. The utility model is the improvement on the basis of the drawing saddle for the original semi-pulling type vehicle. The optimal state of the matching of a drawing pin and a lock body is ensured. The utility model is characterized in that the drawing pin and the lock body are in the changing body of the shape of U. A wrench handle is a lever type. A supporting frame is a downward arrangement type. The front half part of the saddle body is semi-circular. The periphery of the saddle body raises. The middle of the saddle body is provided with a half ring concave oil containing groove.
Description
The utility model relates to a kind of superimposed trailer traction saddle that connects main car and trailer, belongs to parts of semi-dragging truck.
Its saddle body of traction saddle of semi-dragging truck is square or polygonal steel casting at present, difficulty of processing is big, the towing pin lock body is to be made of two semi-ring formula lock dogs, when driving owing to the towing pin and the lock body friction of main car are worn and torn, make main car towing pin and cooperating of lock body gap and increasing occur, be prone to main car and trailer and take off the train operation accident of colluding, original bearing shell is a rigidity, be hard contact, quick abrasion.
The purpose of this utility model is to overcome the weak point in the background technology and a kind of processing in light weight, easy is provided, and it is safe and reliable that the towing pin lock body is in operation, main car towing pin and the superimposed trailer traction saddle that cooperating of lock body is in optimum regime all the time.
The purpose of this utility model be achieved in that it by saddle body, towing pin lock body, remove handle, support, minor axis, bearing, bush seat and form, its support is an one by minor axis, bearing and saddle sports association, bush seat and saddle body weld together, the traction lock body is fixed on the centre of saddle body by axle, cooperate with the towing pin of main car, towing pin lock body of the present utility model is " U " glyph variants body; Remove being lever, its middle part connects as fulcrum and the activity of saddle body, removes the middle and lower part of handle and fixes a relief spring, and the other end of spring hangs on the saddle body; Support is a underneath type; Saddle body forebody is garden shape, Gu drum is played on the limit, the centre has the semi-ring spill to contain oil groove.
The utility model can also be realized by following measure: bearing is a rubber shaft bearing, and inhibiting device of welding is established a slide block in the chute of towing pin lock body bottom on the saddle body on the back shrouding on the saddle body.
The utility model is compared background technology and is had following advantage:
1, because the saddle body is a rolled-up stock, thus material-saving, in light weight, intensity is big, is garden shape in addition, and mold is easy to do, easily processing.
2, the towing pin lock body is in operation safe and reliablely, even towing pin and lock body friction and when wearing and tearing are arranged are fastening at any time owing to there being safe extension spring pulling to remove promoting slide block, makes towing pin and cooperating of lock body be in optimum regime all the time.
3, because of removing an employing lever, so laborsaving, manoeuvrable is reliable.
4, because support has adopted underneath type, simple in structure, low cost of manufacture, easily processing.
5, in use rotation amount is little for superimposed trailer traction saddle, thereby the bearing that has adopted rubber to make, and it has damping of vibrations, thereby has increased the service life of semi-dragging truck.
The drawing explanation of accompanying drawing:
Fig. 1 is the utility model running condition scheme drawing.
Fig. 2 is a structural representation of the present utility model.
Embodiment describes the utility model in detail below in conjunction with (accompanying drawing): as shown in Figure 1, by two supports (4) vehicle traction saddle (2) is fixed on the crossbeam of main car (1), towing pin lock body in the traction saddle (2) locks together the towing pin of trailer (3) front end, and main car (1) and trailer (3) are connected as a single entity under the effect of traction saddle (2).Support (4) is positioned at the below of saddle body (10), be fixed by bolts on the crossbeam of main car (1), support (4) combines as a whole with saddle body (10) by minor axis (17), rubber shaft bearing (16), bush seat (5), bush seat (5) and saddle body (10) weld together, the traction lock body (12) that is " U " glyph variants body is fixed on the centre of saddle body (10) with axle, and saddle body (10) is used A
3Plate compression moulding, its forebody is garden shape, periphery plays drum, the centre has the semi-ring spill to contain oil groove, removing (15) is lever, the middle part is that fulcrum (14) is connected with axle with saddle body (10), a relief spring (9) is fixed in the middle and lower part of (15) removing, the other end of relief spring (9) hangs on the saddle body (10), remove the lower end of (15) is fixed with pull pin (13), folding extension spring (8) one ends are fixed on the towing pin lock body (12), the other end is fixed on the preceding shrouding on the saddle body (10), be fixed with stop gear (7) on the shrouding of back, it ensures that towing pin lock body (12) is in best deployed position all the time, thereby makes the smooth combination of main trailer.Slide block (11) is positioned at the chute of traction lock body (12) lower saddle body (10).Main car (1) and superimposed trailer (3) when unsnaping, need be unloaded safety plug (6), will remove then (15) are promoted (as Fig. 2 long and two-short dash line position).Under the effect of lever, remove pull pin (13) of (15) other end are shifted out slide block (11), along with the reach of main car (1), towing pin lock body (12) just rotates an angle, and towing pin has just been thrown off.Towing pin lock body (12) is under the effect of folding extension spring (8), will withstand slide block (11) and forever keep open configuration as long as main car (1) and trailer (3) separate it, under the cooperation of stop gear (7), make towing pin lock body (12) be in best deployed position all the time.
Claims (4)
1, a kind of superimposed trailer traction saddle, comprise saddle body, towing pin lock body, remove handle, support, minor axis, bearing, bush seat, its support is an one by minor axis, bearing and saddle sports association, bush seat and saddle body weld together, the towing pin lock body is fixed on the centre of saddle body by axle, cooperate with the towing pin of main car, it is characterized in that:
