Abstract
The utility model relates to a towing device of a conveying vehicle, specifically to a semitrailer towing plate. The towing plate comprises a towing plate body and a pin hole and is characterized in that a first projection is arranged at the geometrical center position of the plate surface of the towing plate body; pluralities of second projections are arranged on the surface of the towing plate body; the pin hole is arranged at the center position of the first projection; a bending upwarping portion is disposed at the front end of the towing plate body. The semitrailer towing plate has the advantages of reducing the thickness of the towing plate, lightening the self-weight of the vehicle and saving steel materials. Further, concave pits formed on the peripheries of the first projection and the second projections can store more lubricating grease, thereby reducing friction between the towing plate and a main machine saddle and prolonging service life of the towing plate and the main machine saddle. Additionally, the bending upwarping portion can fulfill great guiding function when a main machine is connected with a trailer, thereby effectively preventing the towing plate from scraping the surface of the main machine saddle.
Description
Technical field
The utility model relates to the draw gear of transport vehicle, specifically a kind of superimposed trailer towing plate.
Background technology
The draw gear of superimposed trailer is with main frame and trailer bonded assembly device.The draw gear of superimposed trailer is generally taked the structure that towing plate is connected with towing pin on the market.Referring to Fig. 4 and Fig. 5: present employed towing plate, its plate face adopts slab construction, is provided with the pin-and-hole 2 that is used to install towing pin in the center of traction plate body 1, if towing plate is thinner, then intensity is not high; For proof strength, have to strengthen the thickness of towing plate, not only steel consumption increases, the corresponding increase of vehicle weight; And the lubricity of towing plate and main frame saddle also can not get improving.Towing plate weight increases, and means that consumptive material increases, and along with rising steadily of price of steel product, the towing plate manufacturing cost increases; Vehicle weight increases, and bring oil consumption height, traffic cost to increase again, and the weight of vehicle self also is restricted.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of intensity big, and consumptive material is few, the superimposed trailer towing plate of towing plate and main frame saddle high lubricating effect.
It is as follows that the utility model solves the problems of the technologies described above the technical scheme of being taked: a kind of superimposed trailer towing plate, comprise traction plate body, pin-and-hole, it is characterized in that: traction plate body plate face geometric centre position is provided with first projection, also be provided with number place second projection on the traction plate body face, pin-and-hole is located at the center of first projection.
When the utility model is made, adopt the method for mould compression moulding to make towing plate, so both improved intensity, can reduce the thickness of towing plate again, alleviate the weight of vehicle itself, and save steel; Because of being provided with first projection and second projection, then formed pit at the periphery of projection, pit can store some lubricating greases more, reduces the friction of towing plate and main frame saddle, increases the service life of the two.

Fig. 2 is the A-A cutaway view of Fig. 1,
Fig. 3 is the B-B cutaway view of Fig. 1,
Fig. 4 is the structural representation of traditional towing plate,
Fig. 5 is the C-C cutaway view of Fig. 4.
The specific embodiment
As shown in Figure 1 to Figure 3: a kind of superimposed trailer towing plate, comprise traction plate body 1, pin-and-hole 2 is characterized in that: traction plate body 1 plate face geometric centre position is provided with first projection 3, also be provided with number place second projection 4 on the traction plate body 1 plate face, pin-and-hole 2 is located at the center of first projection 3.
As of the present utility model perfect, the front end of traction plate body 1 is provided with bending perk 5 upwards; Like this, have good directional tagging when main frame is connected with trailer, actv. has been avoided towing plate scratch main frame saddle surface.
Claims (2)
1, a kind of superimposed trailer towing plate, comprise traction plate body, pin-and-hole, it is characterized in that: described traction plate body (1) plate face geometric centre position is provided with first projection (3), also be provided with number place second projection (4) on described traction plate body (1) the plate face, described pin-and-hole (2) is located at the center of described first projection (3).
2, a kind of superimposed trailer towing plate as claimed in claim 1 is characterized in that: the front end of described traction plate body (1) is provided with bending perk (5) upwards.
