Abstract
The utility model relates to semitrailer field, is a kind of movable towing plate device of semitrailer.It is characterized in that connecting cross beam is fixed on vehicle frame H-girder, the axis of revolution of traction flap is fixed on connecting cross beam, and there is towing pin the lower end of traction flap.Owing to having adopted the technical program, under rugged road environment and field when transportation, tractor truck crossbeam and trailer crossbeam are played a protective role, prevent that frame beam from turning round bad, traction seat, the towing pin phenomenon that fractures.Be applicable to road transport, again the non-road transport of special adaptation and field transportation.
Description
Technical field
The utility model relates to semitrailer field, is a kind of movable towing plate device of semitrailer.
Background technology
Traction saddle is that tractor truck is used for the drawing piece of tractive superimposed trailer.Have two kinds of structures, different by the degree of freedom allowing, have mono-pendulum type saddle, double pendulum type saddle minute.Conventional is mono-pendulum type saddle, i.e. fluctuating action radius before and after having allowed according to the road conditions of travelling after traction seat link trailer, and it can only make around bearing pin center the pendulum that longitudinally inclines of 8 ° of left and right.This type of traction seat has higher riding stability, is applicable to the high speed of travelling on better road surface, the superimposed trailer that underloading and barycenter are higher, and multiplex at van container superimposed trailer and high goods platform, on freight semitrailer in bulk, the torque that vehicle frame bears is larger; For the transportation of large part, heavy special equipment transportation, mono-pendulum type far away can not meet requirements, conventionally adopts double pendulum type saddle, and traction seat can also swing except swing, under different road environments, tractor truck crossbeam is played a protective role.But all have can not swing and rotate in vehicle-height direction.
Summary of the invention
The purpose of this utility model is the movable towing plate device that a kind of semitrailer will be provided.Movable towing plate device belongs to the traction of plurality of pendulums formula, coordinate with mono-pendulum type saddle or double pendulum type saddle, realized multiple degree of freedom traction, this movable towing plate device can not only be made around bearing pin center longitudinally inclining outside pendulum and swing of 8 ° of left and right, can also realize the swing in vehicle-height direction and the rotation along axis of revolution center of tractor truck or trailer.
The technical solution of the utility model is: a kind of movable towing plate device of semitrailer, it is characterized in that connecting cross beam is fixed on vehicle frame H-girder, and the axis of revolution of traction flap is fixed on connecting cross beam, and there is towing pin the lower end of traction flap.
Owing to having adopted technique scheme, under rugged road environment and field when transportation, tractor truck crossbeam and trailer crossbeam are played a protective role, prevent that frame beam from turning round bad, traction seat, the towing pin phenomenon that fractures.Be applicable to road transport, again the non-road transport of special adaptation and field transportation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In the drawings: 1, vehicle frame H-girder; 2, connecting cross beam; 3, axis of revolution; 4, traction flap; 5, towing pin.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
In Fig. 1, connecting cross beam 2 is fixed on vehicle frame H-girder 1, and the axis of revolution 3 of traction flap 4 is fixed on connecting cross beam 2, and there is towing pin 5 lower end of traction flap 4.
One group of concentric connecting cross beam 2 of lateral centre design processing at vehicle frame H-girder 1, traction flap 4 is connected and is tightened by bolts with the connecting cross beam 2 of vehicle frame by axis of revolution 3, can realize like this because Uneven road makes the swing in vehicle-height direction and the rotation along axis of revolution center of tractor truck or trailer, also realize conventional doing longitudinal swing, laterally swing around longitudinal axis along axis of pitch simultaneously.
