Abstract
The utility model relates to a saddle-type traction connector of a traction frame. The top plate (7) of a saddle body is formed in punch by a steel plate. A front grid plate and a back grid plate (5), (6) on the bottom of the top plate and the left side plate and the right side plate (1), (2) on the bottom of the top plate are mutually connected and inserted to form a welded structure and to become reticular, and are integrally fixedly welded on the bottom of the top plate (7) of the saddle body. The connection and insertion reticular welded structure of the bottom of the saddle seat can effectively convert partial pressure on the top plate into integral stress through the connection and insertion structure. Welding spots can be reduced. So the problem that partial stress creates deformation can be avoided. So the service life of the product and the loading rating of the product can be improved under the condition of no change of the prior art and components.
Description
The utility model relates to the combination of tractor truck-trailer, particularly relates to an a kind of car carries the main portion of another car goods by the device at another car front portion of its supporting that has or rear portion saddle drawbar frame traction coupling.
Saddle drawbar frame traction coupling is made up of saddle body, support and towing pin lock body and steering unit, wherein the saddle body is coupled as one by bearing and minor axis and two supports, and can forward and backward swing on support, support directly is fixed on the crossbeam of tractor truck, and towing pin is locked in the towing pin lock body by steering unit.As Chinese patent CN2156096 number disclosed a kind of saddle drawbar frame traction coupling that comes to this.
Above-mentioned traction coupling, the top board of its saddle body is to be formed by the steel plate compacting, the centre that oblong location that forward and backward shrouding and left and right side plate are formed and spacing sheet frame are fixedly welded on the top board bottom surface, saddle sports association connects the fixing welding in the top board place semicircle holder of support portions.Because the load that is added on the saddle body top board is delivered on the support by the semicircle toss, the top board at semicircle holder position obtains the supporting of support, and load is then born by the intensity of self fully in all the other positions of top board, makes the top board of saddle body easily produce local deformation.And the application force that tractive force produces saddle body top board mainly concentrates on the centre of top board, also easily makes top board produce deformation.In addition, sheet frame is that solder joint is many more by welding and top board secure bond, causes roof deformation easily more, and prior art must be carried out the large tracts of land welding.These factors greatly reduce the load-carrying grade of the service life and the product of product.
Main goal of the invention of the present utility model is to provide a kind of can overcome the defective that above-mentioned technology exists, the traction coupling with stronger saddle body structure intensity.
Second goal of the invention of the present utility model is to provide a kind of pressure or tractive force of can making as far as possible reasonably to be distributed on the top board, to improve the traction coupling of saddle body structure intensity.
Goal of the invention of the present utility model is achieved in that on the basis of existing saddle drawbar frame traction coupling, with the simple welded structure between present location, the spacing sheet frame, be improved to the welded structure that patches mutually, make it to become a integral body in conjunction with firm; In addition the location, positioning plate patching on the basis of structure, forms latticed, and with the bottom of saddle body top board fixing weldering knot formation one integral body.
On specific design, have plug receptacle on left and right interior plate and two blocks of tail lattice plates, forward and backward lattice plate (being forward and backward shrouding) is a plug-in unit, forward and backward lattice plate is plugged on the plug receptacle of left and right inboard, the socket of two blocks of tail lattice plates is inserted on the left and right interior plate, the plug receptacle place is fixing for welding, and the pinboard integral solder is fixed on the bottom surface of top board.
Semicircle holder and scapulet also can be taked the mode of connector as the parts of main holding capacity, form with interior plate and lattice plate patch, welded structure.Be that side plate has on its corresponding position and the corresponding to socket of semicircle holder shape, the semicircle holder patches, welds thereon, and is weldingly fixed on top board; Scapulet also be with forward and backward lattice plate on socket patch, weld fixing, and together be welded on the top board bottom surface.
For convenient welding be semicircle holder filling lubricating oil, top board and semicircle holder contact site have through hole, and the through hole radius of top board is greater than the radius of semicircle holder through hole, so that make the two secure bond better from welded top.In addition, top board is provided with the bowtie shaped slot of drawing, strengthens the integral surface structure of top board, can allow lubricating oil be formed on the attrition surface of saddle body, and they are back on lock body and the towing pin.
Saddle bottom this patches netted welded structure, can reduce weld nugget between sheet frame and the top board, thereby, can avoid welding the distortion that causes, reach better planeness.In addition, patching welded structure can effectively that top board is suffered local pressure, form whole stressed by this structure that patches, avoid local pressure to produce the difficult problem of distortion, and can under the situation that does not change existing technology and parts, improve the service life of product and the load-carrying grade of product.
Below with reference to accompanying drawing an embodiment of the present utility model is described in detail.
Fig. 1 is a saddle body of the present utility model bottom surface structural representation;
Fig. 2 is the structural representation at interior plate position, Fig. 1 left side.
Referring to Fig. 1, Fig. 2.The left and right interior plate (1) of saddle body, (2) and tail lattice plate (3), (4) are provided with plug receptacle (as (13) of left side board, forward and backward lattice plate (5), (6) are plug-in unit, forward and backward lattice plate is plugged on the plug receptacle of left and right interior plate, the socket of two blocks of tail lattice plates is inserted on the left and right interior plate, the welding of plug receptacle place is fixing, and the pinboard integral solder is fixed on the bottom surface of top board (7).Have on interior plate (1), (2) and the corresponding to socket of semicircle holder (9) shape (8), the semicircle holder patches, welds thereon, and is weldingly fixed on top board; Socket on scapulet (10) and forward and backward lattice plate (5), (6) patches, welds fixing, and is together to be weldingly fixed on top board (7) bottom surface.Top board (7) has through hole (11) and (12) with semicircle holder (9) contact site, and the through hole radius of top board is greater than the radius of semicircle holder through hole, and the butterfly that top board (7) is provided with drawing contains oil groove (14).
