Abstract
The utility model discloses a drawing device for tractor, consisting of a drawing rack, a drawing fork and a pin shaft. The semi-shaft sleeve of the tractor is connected with the drawing rack by adopting a connecter, and the drawing rack and the drawing fork are connected by adopting a shaft and a shaft sleeve; the connecter has a connecting plate and a connecting ear which are an integration, the connecting plate is provided with a screw hole, the connecting ear is provided with a pin shaft hole, and the connecting plate of the connecter and the semi-shaft of the tractor are fixed by screw bolts; the center of the drawing rack is provided with the shaft sleeve, and the front end of the drawing rack is provided with the connecting ear which is movably connected with the connecting ear of the connecter; the front end of the drawing fork is provided with the shaft, the back end of the drawing fork is provided with three layers of fork plates, the shaft is penetrated through the shaft sleeve of the drawing rack and is fixed on the front end of the shaft sleeve by using nuts. After the connecter is connected with the semi-shaft of the tractor and the drawing rack, the dynamic force points moving up and down in the drawing device are on the connecting point of the drawing rack and the connecter, the dynamic force points of the tractor are moved forward, the distance of the dynamic force point of the semi-shaft is shortened, and a front vehicle and a full trailer are freely twisted; when a road is rugged or the full trailer happens side turning, the front vehicle doesn't happen the side turning following the full trailer.
Description
Technical field:
The utility model relates to a kind of draw gear of trac..
Background technology:
Draw gear is the connecting device of trac. and trailer, the present trac. that uses, its draw gear is movable fixing with bearing pin by towing fork and drawbar frame, the front end of drawbar frame connects the half-axile sleeve of trac., with the half-axile sleeve bolt of trac., the half-axile sleeve of drawbar frame and trac. becomes one.After the connection, the joint that up and down power point flexibly connects at the front end of the rear portion of drawbar frame and towing fork in the draw gear.This project organization of the prior art makes that up and down power point is long with the distance of semiaxis in the draw gear, and promptly the arm of force is long, when trailer is heavier or when missing the bus, turns over behind the headstock before making because the arm of force is long, causes the accident, even hurts sb.'s feelings.
Summary of the invention:
Goal of the invention of the present utility model is to provide a kind of tractor traction device at the problems referred to above, shortens the distance of power point with semiaxis up and down in the draw gear, reduce or prevent to cause trac. because of the distance of power point and semiaxis is long after turn over phenomenon.
The technical solution of the utility model is: a kind of tractor traction device adopts attaching parts to be connected between shaft of tractor cover and drawbar frame, adopts between drawbar frame and the towing fork spool to be connected with axle sleeve; Attaching parts has connecting panel and engaging lug, and connecting panel and engaging lug are one, and connecting panel has screw, and pin shaft hole is arranged on the engaging lug, and connecting panel and shaft of tractor in the attaching parts are applied mechanically bolt; There is axle sleeve at the drawbar frame center, and front end has engaging lug, and the engaging lug of engaging lug and attaching parts flexibly connects with bearing pin; The towing fork front end has axle, and there are three layers of fork plate the rear end, and axle passes the axle sleeve in the drawbar frame, fixes with nut at the front end of axle sleeve.
Advantage of the present utility model and beneficial effect:
The utility model has changed the structure of drawbar frame, adopts attaching parts to be connected between shaft of tractor cover and drawbar frame, and the distance that attaching parts and shaft of tractor can be overlapped is approaching.After the connection, up and down power point makes the power point reach of trac. at the joint of drawbar frame and attaching parts in the draw gear, and the distance of power point and semiaxis shortens greatly; Towing fork has three layers of fork plate, and the spacing between the fork plate is dwindled, and the up and down distance of car is dwindled before and after making, and traction is steady, and reversing flexibly; The axle of towing fork front end inserts the axle sleeve of drawbar frame, and the axle of towing fork rotates in the axle sleeve of drawbar frame, and front truck and trailer are freely twisted, and when road injustice or trailer generation rollover, front truck is rollover thereupon not.
The utility model description of drawings:
Fig. 1 is an integral structure scheme drawing of the present utility model;
Fig. 2 is the structural representation of attaching parts in the utility model.
Among the figure: 1 connecting panel, 2 drawbar frames, 3 pads, 4 axle sleeves, 5 towing forks, 6 bearing pins, 7 bearing pins, 8,9 opening pins, 10 springs, 11 links, 12 nuts, 13 connecting panels, 14 engaging lugs, 15 engaging lugs.
The specific embodiment:
Example 1: according to shown in Figure 1, the tractor traction device by attaching parts 1, drawbar frame 2, towing fork 5, form, on the connecting panel 13 of attaching parts 1 screw is arranged, fix with the half-axile sleeve of screw and trac..The engaging lug 14 of attaching parts 1 has two pin shaft holes, also can be designed as three, mainly is the distance up and down that is used to regulate the towing fork assembly, penetrates with the engaging lug 15 usefulness bearing pins 6 of drawbar frame 2 front ends, in the hole of bearing pin 6 front ends, insert opening pin 9, drawbar frame 2 and attaching parts 1 are flexibly connected.Drawbar frame 2 front ends have engaging lug 15, and there is axle sleeve 4 centre, and the internal diameter of axle sleeve 4 guarantees that the front axle 8 of towing fork 5 passes, also can rotate in axle sleeve 4.Towing fork 5 front ends have axle 8, and the front end of axle 8 has pin hole, and there are three layers of fork plate the rear end, on the fork plate link 11 is arranged, and the front end of bearing pin 6,7 is porose, and nut 12 1 ends are jagged.Axle 8 passes the axle sleeve 4 of drawbar frame 2, and is fixing in the front end outside of axle sleeve 4 with nut 12, inserts opening pin 9 in the indentation, there of axle 8 front end pin holes and nut 12.
Between the upper end of the bonnet of towing fork 5 and trac., spring 10 is arranged, one end of spring 10 is connected link 11, and the other end connects the upper end of the bonnet of trac., and spring 10 hangs towing fork 5 and drawbar frame flat, natural equilibrium, bearing pin 7 are used for being connected of draw gear and trailer.Present embodiment is applicable on the existing trac. and reequips.
Example 2: another embodiment of the present utility model, the attaching parts 1 in the technique scheme is an one with the shaft of tractor cover, directly processes when half-axile sleeve is cast.Present embodiment is applicable to when producing tractors, direct process mating.
