Description
Technical field
The utility model relates to trailer technical field, in particular to a kind of hitch frame suitable for trailer.
Background technique
For trailer especially central axle trailer, the structure of hitch frame is most important, and hitch frame is firstly the need of receiving
The tractive force and brake force of full trailor operation.The form that the hitch frame of existing trailer mostly uses greatly bail to add draw beam is welded on
On the vehicle frame of trailer, since trailer load-carrying increases, and general running time is longer, and after hitch frame damage, replacement is not easy.And only
Only with bail plus the hitch frame of draw beam form, common intensity is not high, and the time used is shorter.General hitch frame and rear car
The connection of frame part uses welded type, and the hitch frame of this structural shape is welded together with vehicle frame in production, wanted in welding
Guarantee welding precision, otherwise there is tractive force sideslip and cause to grind tire, while the followability of trailer is poor.
Summary of the invention
In order to overcome the shortcomings in the prior art, the utility model provide it is a kind of give repair and replacement be suitable for trailer
Hitch frame, technical solution is：A kind of hitch frame suitable for trailer, composition include bail, draw beam and rear haulage
Device, the bail are fixedly mounted on the front end of draw beam, and the tail end of the draw beam is fixedly installed with rear towing device, institute
State rear towing device include while stringer one, while stringer two and rear cross beam, it is described while stringer one and while stringer two the fixed weldering in top
Be connected together, it is described while stringer one and while stringer two top be fixedly welded on the tail end of draw beam, the both ends of the rear cross beam
Be fixedly welded on respectively while stringer one and while stringer two bottom, it is characterised in that：It is described while stringer one and while stringer two bottom
End is respectively arranged with the mounting rail one and mounting rail two being parallel to the horizontal plane, and is provided on the mounting rail one and mounting rail two
Bolt mounting holes, it is described while stringer one and while stringer two outside be fixedly welded with reinforcing beam one and reinforcing beam two, it is described plus
The bottom of brutal one and reinforcing beam two is respectively arranged with mounting surface one and mounting surface two, and the mounting surface one and mounting surface two are distinguished
In the same horizontal line with mounting rail one and mounting rail two, bolt installation is provided on the mounting surface one and mounting surface two
Hole.
It is described while stringer one and while stringer two middle part be provided with front beam, the both ends of the front beam are fixedly welded respectively
While stringer one and while stringer two middle part, the front beam is parallel with rear cross beam.
It is described while stringer one, while stringer two and rear cross beam formed an isosceles triangle.
The utility model has the beneficial effects that：
1, traction frame body uses welded type, and bail uses fabricated construction, and the connection of hitch frame and vehicle frame is using dress
With formula, high strength steel is can be used in the material of hitch frame, this kind of structure had both met intensity and rigidity requirement, while also being met light
Quantization requires.
2, the connection of hitch frame and vehicle frame uses assembled, and using being bolted, in production, traction can with vehicle frame in this way
To be fabricated separately, it is conducive to batch production.Assembly precision is adjustable simultaneously, fastens after adjusting, it is ensured that the precision of assembly.
3, it since hitch frame uses assembled, is more convenient in maintenance and repair, it, can be only in the case where hitch frame is impaired
Hitch frame is changed, without replacing entire hitch frame band vehicle frame.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the assembly state diagram of the utility model.
In figure：Bail 1, draw beam 2, side stringer 1, side stringer 24, front beam 5, rear cross beam 6, reinforcing beam 1 add
Brutal 28, mounting rail 1, mounting rail 2 10, mounting surface 1, mounting surface 2 12.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
In fig. 1 and 2, a kind of hitch frame suitable for trailer, composition include bail 1, draw beam 2 and rear haulage
Device, the bail 1 are fixedly mounted on the front end of draw beam 2, and the tail end of the draw beam 2 is fixedly installed with rear haulage dress
Set, the rear towing device include while stringer 1, while stringer 24 and rear cross beam 6, it is described while stringer 1 and while stringer 24
Top is fixed and welded together, it is described while stringer 1 and while stringer 24 top be fixedly welded on the tail end of draw beam 2, it is described
The both ends of rear cross beam 6 be fixedly welded on respectively while stringer 1 and while stringer 24 bottom, it is characterised in that：The side stringer one
3 and the bottom end of side stringer 24 be respectively arranged with the mounting rail 1 and mounting rail 2 10 being parallel to the horizontal plane, the mounting rail 1
Be provided with bolt mounting holes on mounting rail 2 10, it is described while stringer 1 and while stringer 24 outside be fixedly welded with plus
The bottom of brutal 1 and reinforcing beam 28, the reinforcing beam 1 and reinforcing beam 28 is respectively arranged with mounting surface 1 and mounting surface
2 12, the mounting surface 1 and mounting surface 2 12 respectively with mounting rail 1 and mounting rail 2 10 in the same horizontal line, it is described
Bolt mounting holes are provided on mounting surface 1 and mounting surface 2 12.
It is described while stringer 1 and while stringer 24 middle part be provided with front beam 5, the both ends of the front beam 5 are fixed respectively
Be welded on while stringer 1 and while stringer 24 middle part, the front beam 5 is parallel with rear cross beam 6.
It is described while stringer 1, while stringer 24 and rear cross beam 6 formed an isosceles triangle.
When assembly, the front end for the vehicle frame that the tail end insertion of hitch frame is needed to equip, the front end of vehicle frame is provided with and installs
The corresponding bolt mounting holes of bolt mounting holes on beam 1, mounting rail 2 10, mounting surface 1 and mounting surface 2 12, pass through
Hitch frame is fixed on the front end of vehicle frame by bolt.Due to being provided with reinforcing beam 1 and reinforcing beam 28 on hitch frame, guaranteeing to fill
Match it is even closer in the case where, intensity also greatly improves.Due to while stringer 1, while stringer 24 and rear cross beam 6 formed one
A isosceles triangle, at the same while stringer 1, while stringer 24 middle part be provided with a front beam 5 parallel with rear cross beam 6,
The intensity and rigidity of hitch frame are increased, to increase the anti-twisting property of hitch frame.Since this hitch frame and vehicle frame use spiral shell
Bolt is fixedly connected, and when hitch frame damage, progress that can be more convenient is replaced in time, in order to avoid influence operating efficiency.
