Abstract
The utility model relates to a full trailer traction frame of a truck. The full trailer traction frame of a truck comprises a traction rod, a traction ring connected at the left end part of the traction rod, and a traction frame body connected at the right end part of the traction rod, wherein the traction frame body comprises a traction frame and a bogie, the traction frame and the bogie are rotatably connected by a connecting shaft; an elastic device is arranged at the rotatable connection part of the traction frame and the bogie along the side beside the axis of the connecting shaft and at a position between the traction frame and the bogie, two ends of the elastic device are respectively connected with the traction frame and the bogie; and a rolling device is arranged in the inner ring of the traction ring. A ball is arranged between the inner ring and the outer ring of a thrust ball bearing, so that a center pin inserted into the inner ring is not easy to fracture due to abrasion, and the friction between the frame and the traction frame is changed from plane friction into rolling friction inside the bearing; therefore, friction loss is greatly reduced, the operation cost is reduced, and the trucking safety factor is improved.
Description
Technical field
The utility model relates to a kind of drawbar frame, particularly a kind of lorry independent trailer drawbar frame.
Background technology
The lorry independent trailer is had many uses general in transit industry, generally couples together wheel tractor and independent trailer through link on the drawbar frame and the hook on the vehicle frame transportation large-tonnage goods.Drawbar frame is used to reduce the turn radius of vehicle in independent trailer, to reduce the requirement of vehicle to road, parking space etc.Because the vehicle frequency of utilization is high, load is big, in Freight Transport, can cause the center pin of drawbar frame and the lower surface undue wear of bogie truck, thereby causes the center pin fracture, and this has brought potential safety hazard for the transportation of lorry independent trailer.If often change center pin or drawbar frame, also can increase operation cost.
The utility model content
The technical matters that the utility model will solve provides a kind of lorry independent trailer drawbar frame, can reduce the frictional loss between vehicle frame and drawbar frame, cuts operating costs, and improves the Freight Transport safety factor.
For solving the problems of the technologies described above; A kind of lorry independent trailer drawbar frame; Comprise draw bar, be connected the eye hitch of draw bar left part and be connected the traction support body of draw bar right part; It is characterized in that: said traction support body comprises drawbar frame and bogie truck; This drawbar frame and bogie truck are rotatably connected through adapter shaft, and side and the position between this drawbar frame and this bogie truck at this drawbar frame and the bogie truck place of being rotatably connected along this adapter shaft axis direction are provided with springing, and the two ends of this springing are connected with this bogie truck with this drawbar frame respectively; Be provided with tourelle in the interior ring of said eye hitch.
Wherein, said tourelle is a thrust ball bearing.
Wherein, said drawbar frame total length is 180 centimetres-230 centimetres.
Compared with prior art, the utility model has the advantages that: 1, said lorry independent trailer drawbar frame can make the friction between vehicle frame and the drawbar frame become bearing in-to-in friction of rolling by planar friction, thereby significantly reduces frictional loss.2, said lorry independent trailer drawbar frame can effectively be buffered under the reverse load effect suffered radial impact power between the drawbar frame and bogie truck, and then the be separated generation of accident of the drawbar frame and the bogie truck that prevent trailer coupling.
Description of drawings
Fig. 1 is the structural representation of the utility model lorry independent trailer drawbar frame.
Fig. 2 is the enlarged diagram of thrust ball bearing.
Among the figure: 1. draw bar, 2. eye hitch, 3. traction support body, 4. thrust ball bearing.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Like Fig. 1, shown in Figure 2. a kind of lorry independent trailer drawbar frame; Comprise draw bar 1, be connected the eye hitch 2 of draw bar 1 left part and be connected the traction support body 3 of draw bar 1 right part; Said traction support body 3 comprises drawbar frame and bogie truck; This drawbar frame and bogie truck are rotatably connected through adapter shaft; Side and the position between this drawbar frame and this bogie truck at this drawbar frame and the bogie truck place of being rotatably connected along this adapter shaft axis direction are provided with springing, and the two ends of this springing are connected with this bogie truck with this drawbar frame respectively; Be provided with tourelle in the interior ring of said eye hitch 2.
Wherein, said tourelle is a thrust ball bearing 4.
Wherein, said drawbar frame total length is 180 centimetres-230 centimetres.
Be provided with tourelle in the ring in the eye hitch 2 of said lorry independent trailer drawbar frame, this tourelle is a thrust ball bearing 4.When eye hitch 2 with fix through center pin after the kingpin hole on the vehicle frame is aimed at.So just can connect to ground drawbar frame, drag trailer through drawbar frame.Be provided with ball between the inner ring of the thrust ball bearing of said lorry independent trailer drawbar frame and outer ring; The center pin that make to insert its inner ring is easy to wear and rupture; Also make the friction between vehicle frame and the drawbar frame become bearing in-to-in friction of rolling, thereby significantly reduce frictional loss by planar friction.
The length of drawbar frame directly influences full manoevreability and stability of hanging lorry.When lorry travelled on ramp or bend, drawbar frame can produce inclination, and tractive force will be passed to independent trailer with certain angle, be unfavorable for the transmission of tractive force.The length of suitable drawbar frame can reduce the power transmission angle, helps the transmission of tractive force.If will increase himself quality, and be unfavorable for turning to and moveing backward but drawbar frame is oversize.So the utility model is decided to be 180 centimetres-230 centimetres with the drawbar frame total length.
The traction support body 3 of the utility model lorry independent trailer drawbar frame; Comprise drawbar frame and bogie truck; This drawbar frame is rotatably connected through adapter shaft with this bogie truck; Side and the position between this drawbar frame and this bogie truck at this drawbar frame and this bogie truck place of being rotatably connected along this adapter shaft axis direction are provided with springing, and the two ends of this springing are connected with this bogie truck with this drawbar frame respectively, and are compressed state; The utility model can effectively be buffered under the reverse load effect suffered radial impact power between the drawbar frame and bogie truck, and then the be separated generation of accident of the drawbar frame and the bogie truck that prevent trailer coupling.
More than show and described groundwork and the principal character and the advantage thereof of the utility model.The technological personage of the industry should understand; The utility model does not receive the restriction of above-mentioned implementing regulations; The principle of describing in above-mentioned implementing regulations and the specification sheets that just is used to explain the utility model; Under the prerequisite that does not break away from the utility model principle and scope, the utility model also can have various changes and modifications, and these variations and improvement all belong in the utility model scope of requirement protection.
The utility model requires protection domain to define with appending claims and other equivalent.
