Abstract
The utility model relates to the field of cargo transportation vehicles, in particular to a trailer gooseneck, which comprises a traction frame, a connecting ring arranged at the head of the traction frame, and a wheel group arranged at the bottom of a trailer and used for bearing the weight of the gooseneck. The trailer gooseneck is characterized by also comprising a traction seat and a pull bar. The traction seat is longitudinally and rotatably connected with the tail of the traction frame. The two sides of the traction seat are respectively provided with a set of wheel group traction fixed holes and the two sets of wheel group traction fixed holes are symmetrically arranged. The wheel group is rotatably connected with one end of the pull bar and the other end of the pull bar is rotatably connected with the traction seat through the wheel group traction fixed holes. Due to the adoption of the trailer gooseneck, the rotation radius of a trailer head that tows a trailer is effectively shortened. Therefore, the steering flexibility of the whole trailer is improved. The trailer gooseneck facilitates the driving of a trailer.
Description
Technical field
The utility model relates to the goods transport vehicular field, is specially a kind of gooseneck boom neck of trailer.
Background technology
The gooseneck of trailer is the transom of tractor truck and trailer, and its afterbody of gooseneck of existing trailer is captiveed joint with trailer, so, owing to only have gooseneck to rotary connection with tractor truck, causes its radius of rotation big, to such an extent as to the underaction that becomes behind the trailer on the trailer headband.
Summary of the invention
The purpose of the utility model is to provide a kind of and is rotationally connected with tractor truck, flexibly connect with trailer, and the tractor truck radius of rotation that has trailer is diminished, and gooseneck more flexibly becomes.
In order to achieve the above object, the utility model is achieved in that
A kind of trailer gooseneck, it comprises drawbar frame, is located at the coupling link of drawbar frame head, the wheels that are arranged at the trailer bottom of carrying gooseneck weight; This gooseneck also comprises traction seat and pull bar; Traction seat and drawbar frame afterbody vertically are rotationally connected, and the traction seat both sides are provided with the wheels traction and fixation hole of one group of symmetry; Wheels are rotaryed connection with an end of pull bar; The other end of pull bar is rotaryed connection with traction seat through wheels traction and fixation hole.
Described trailer gooseneck, wheels horizontally rotate and are connected in the trailer bottom.
The utility model adopts above-mentioned design, and itself and tractor truck, trailer are flexible connection, the radius of rotation in the time of can effectively shortening the tractor truck balanced full trailer, thus improved the flexibility ratio that turns to of full car, for going of trailer brings convenience.
Description of drawings
Fig. 1 is the utility model and trailer, trailer bonded assembly scheme drawing.
Fig. 2 is the birds-eye view of the utility model.
Fig. 3 is the schematic perspective view of the utility model drawbar frame, traction seat.
The specific embodiment
Below further specify the utility model through specific embodiment.
Like Fig. 1, Fig. 2, shown in Figure 3, a kind of trailer gooseneck, it comprises drawbar frame 1, is located at the coupling link 3 of drawbar frame 1 head, the wheels 4 that are arranged at the trailer bottom of carrying gooseneck weight; This gooseneck also comprises traction seat 2 and pull bar 5; Traction seat 2 vertically is rotationally connected with drawbar frame 1 afterbody, and traction seat 2 both sides are provided with the wheels traction and fixation hole of one group of symmetry; Wheels 4 are rotaryed connection with an end of pull bar 5; The other end of pull bar 5 is rotaryed connection with traction seat 2 through wheels traction and fixation hole.
The gooseneck of described trailer, two pairs of wheels 4 symmetries horizontally rotate and are connected in the trailer bottom.
The advantage of the utility model is that itself and tractor truck, trailer are flexible connection, the radius of rotation in the time of can effectively shortening the tractor truck balanced full trailer, thus improved the flexibility ratio of full car, for going of trailer brings convenience.
