Abstract
The utility model discloses a semitrailer towing device, comprising a traction base provided with a V-shaped open slot. The bottom of the open slot is connected with an opened circular through hole and the middle part of the base is provided with a latch hook component. The lower part of the base is provided with a support seat and an abrasion-proof panel is arranged on the traction base while an integral reinforcing rib is arranged on the bottom of the base. The surface of the traction base is provided with an abrasion-proof panel assemblage step and the height of the assembled abrasion-proof panel is higher than the height of the traction base. The utility model has simple and reasonable structure and because of the traction base adopting a large circular arc structure, the base stamped integrally and the integral frame reinforcing ribs arranged on the bottom of the base, the carrying capacity of the utility model is improved greatly. The abrasion-proof panel made of ultrahigh molecular weight polyethylene has good abradability and the combination of multipoint oil supply and unique oil path provides good lubrication effect; the abrasion-proof panel design with the height over the base surface and the replaceable abrasion-proof panel structure greatly prolong the service life of the base.
Description
Technical field
The utility model relates to the superimposed trailer draw gear of mechanical connection between a kind of saddle tractor and the superimposed trailer.
Background technology
The superimposed trailer draw gear is the special purpose parts of various tractor trucks, and it is installed on the vehicle frame before the tractor truck back axle, realize between tractor truck and the superimposed trailer coupling with separate.Draw gear connects by lockable mechanism and superimposed trailer towing pin in order to bear the anterior load of superimposed trailer, transmitting tractive power and braking force, and can finish the device that connects the superimposed trailer towing pin automatically.The profile of existing draw gear is generally square, adopts welding or cast structure.Its weight is big, and defective is many, and is easy to wear, and the more problem that in use produces, and can influence traffic safety frequently, so make us not too satisfied.
Summary of the invention
It is a kind of simple and reasonable that the purpose of this utility model is to provide, and the superimposed trailer draw gear of big, the wear-resistant and replaceable wear panel of load-carrying capacity is to overcome weak point of the prior art.
By a kind of superimposed trailer draw gear of this purpose design-calculated, comprise the traction pedestal, pedestal is provided with the V-shape open slot, this open slot base portion has been close to an opening manhole, the pedestal middle part is provided with the touching hook parts, the pedestal bottom is provided with bearing, and its architectural feature is that the traction pedestal is provided with wear-resisting panel, and base bottom is provided with the integral type reinforced rib.
Above-mentioned traction base-plates surface is provided with symmetrical wear-resisting panel assembly support rank, and the height of the wear-resisting panel after the assembling is a little more than the traction pedestal.Wear-resisting panel is weldingly fixed on the traction pedestal by multiple spot.Reinforced rib joins with the downward bending branch of traction susceptor edges, fuses.The traction pedestal is provided with the great circle arc structure.The traction pedestal is provided with the multiple spot oilhole, and base-plates surface is provided with and is the oil groove that big font distributes.
The utility model is simple and reasonable, because the traction pedestal adopts the great circle arcuate structure, and the whole punch forming of pedestal, base bottom is provided with the integral frame-type reinforced rib, so its overall weight is light, rigidity is big, and is more shock-resistant, and load-carrying capacity is greatly improved; Adopt the wear-resisting panel of welded type, the operating cycles of product obtains prolonging, and exchangeable panel; The wear-resisting panel that adopts ultrahigh molecular weight polyethylene to become has more resistance to abrasion, and non-maintaining, the fast changeable panel is beneficial to environmental protection; The multiple spot fuel feeding combines with the oil circuit mode of uniqueness, and good lubricating effect more is provided; Exceed the wear-resisting panel designs of base-plates surface and the service life that interchangeable wearing face plate structure has prolonged the traction pedestal greatly.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1-Figure 11, this superimposed trailer draw gear, traction pedestal 3 surfaces of great circle arc structure are provided with symmetrical assembling step 4, and wear-resisting panel 2 is contained in this step 4.After the assembling, the surface elevation of wear-resisting panel 2 is seen Fig. 1, Fig. 7 and Figure 10 a little more than traction pedestal 3.Wear-resisting panel 2 adopts multiple spot welding manner and pedestal to join, and the panel 2 after the wearing and tearing can change.Wherein, wear-resisting panel 2 also can adopt superhigh molecular weight polyethylene material to make, can be by being bolted on the traction pedestal 3.Traction pedestal 3 front portions are provided with the V-shape open slot, and this open slot base portion has been close to an opening manhole, and flow ring 1 is installed on the manhole of pedestal 3 by bolt, sees Fig. 4-Fig. 6, Fig. 8.Pedestal 3 middle parts are provided with the touching hook parts, and the touching hook parts comprise an end and joystick 10 pivotally attached levers 9, and the other end of lever 9 is hinged by slotted hole and pedestal 3 on it, and its middle part is hinged with locking bolt 8; Latch hook 7 joins with pedestal 3 by an eccentric pin 5, and the other end of an end of extension spring 6 and the pin hole homonymy of latch hook joins, and its other end and pedestal 3 join, and see Fig. 1, Fig. 3 and Fig. 4.Pedestal 3 bottoms are provided with bearing 11, see Fig. 2, and pedestal 3 bottoms also are provided with integral type reinforced rib 32, and this reinforced rib 32 joins with the downward dogleg section in traction pedestal 3 edges, fuses, and sees Fig. 9.Traction pedestal 3 is provided with multiple spot oilhole 33, and pedestal 3 surfaces are provided with and are the oil groove 31 that big font distributes, and oilhole 33 communicates with oil groove, sees Fig. 8 and Fig. 9.When the lock pin of superimposed trailer bumped against latch hook 7, latch hook 7 was because its accentric is provided with, and under the effect of extension spring 6, latch hook 7 rotates around its eccentric pin 5, the part that it is short, and the left side of latch hook 7 just, the lock pin that turns over just in time superimposed trailer blocks; Simultaneously, come, block latch hook 7, it can not be turned round, thereby guarantee that lock pin is pinned by latch hook 7, guarantee to be connected firmly between tractor truck and the superimposed trailer, see Fig. 1, Fig. 3, Fig. 4 and Figure 11 with lever 9 bonded assembly locking bolts 8 parallel motions.
