Abstract
The invention discloses a three-dimensional hinged body for connecting a vehicle frame, which comprises a hinged body rear seat and a hinged body front seat, wherein the hinged body rear seat is provided with a traction shaft; and the hinged body front seat and the hinged body rear seat are hinged together by two hinge shafts which share a central line. The hinged body front seat and the hinged body rear seat are hinged together through the hinge shafts which share the central line, so the length of each hinge shaft is much shorter than that of the conventional hinge shaft. Under the condition of the same diameter, the hinge shafts of the three-dimensional hinged body, which have a small length, have a higher bearing capacity than long hinge shafts of the conventional products of the same kind. Because of the two hinge shafts, the overall bearing capacity of the three-dimensional hinged body is much higher than those of the conventional products of the same kind.
Description
Technical field
The present invention relates to the automotive engineering field, relate in particular to the three-dimensional articulated body of the forward and backward vehicle frame of a kind of junctor motor-car.
Background technology
Existing self-propelled vehicle connects forward and backward vehicle frame and often uses three-dimensional articulated body.Existing three-dimensional articulated body comprises that the articulated body back seat is provided with axis of traction, is arranged with the traction axle sleeve during use on the axis of traction by an articulated body back seat and an articulated body front stall that the hinge pin axle is hinged, and the traction axle sleeve is fixedly connected on the vehicle frame of back.Wherein, the middle part of hinge pin axle is installed on the articulated body back seat by two cone bearings, and the two ends of hinge pin axle are located on the articulated body front stall.The bottleneck of the bearing capacity of this three-dimensional articulated body is the hinge pin axle that it is long.Simultaneously, because this hinge pin axle can only be installed by two cone bearings, therefore single cone bearing is stressed bigger, thereby has limited three-dimensional articulated body single-piece bearing capacity.
Summary of the invention
The object of the present invention is to provide a kind of more three-dimensional articulated body of connection vehicle frame of large bearing capacity that has.
For achieving the above object, the three-dimensional articulated body of connection vehicle frame of the present invention comprises articulated body back seat and articulated body front stall, and the articulated body back seat is provided with axis of traction, and described articulated body front stall and articulated body back seat are hinged by the hinge pin axle of two concentricity lines.
Described articulated body front stall and articulated body back seat are hinged by the hinge pin axle of two concentricity lines, and the length of every hinge pin axle just can shorten more greatly like this.Under the identical situation of diameter because contraction in length, therefore the bearing capacity of every hinge pin axle of the present invention more than or equal in the like product in the past than the bearing capacity of band andgudgeon bearing pin; Because the present invention has two hinge pin axles, thus total bearing capacity more in the past like product improve greatly.In addition, make when of the present invention, the width between centers of two hinge pin axles can be adjusted according to the needs that connect forward and backward vehicle frame, makes the model of different width between centerss.
The middle part of every hinge pin axle all is installed on the articulated body back seat by two cone bearings and its two ends are located on the articulated body front stall.
All install by two cone bearings at the middle part of every hinge pin axle, so total bearing capacity will be dispersed on four cone bearings, and the stressed of single cone bearing reduced more greatly, and this has also improved bearing capacity of the present invention.
In a word, the present invention is simple in structure, and is easy to use, and four cone bearings can be installed easily, improves load-carrying capacity under the prerequisite that does not increase the hinge pin shaft diameter greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is a running condition reference diagram of the present invention.
The specific embodiment
" preceding " in the present embodiment, " back ", " on ", direction such as D score is as the criterion with the use state, wherein " preceding " is the headstock direction of self-propelled vehicle 18.
As shown in Figure 1 to Figure 3, connection vehicle frame of the present invention comprises articulated body back seat 2 and articulated body front stall 1 with three-dimensional articulated body, articulated body back seat 2 is provided with axis of traction 3, and described articulated body front stall 1 and articulated body back seat 2 are hinged by the hinge pin axle 5 of two concentricity lines.Wherein, the middle part of every hinge pin axle 5 all is installed on the articulated body back seat 2 by two cone bearings 6 and its two ends are located on the articulated body front stall 1.
As Fig. 3 and Fig. 1, shown in Figure 2, during use, be arranged with traction axle sleeve 4 on the axis of traction 3, traction axle sleeve 4 is fixedly connected on the vehicle frame 12 of back, thereby back vehicle frame 12 can be rotated around axis of traction 3 in perpendicular to ground-surface vertical plane with traction axle sleeve 4; Articulated body front stall 1 is installed on the front vehicle frame 13, can rotate mutually in the horizontal direction between the forward and backward seat 1,2 of articulated body, therefore, can be implemented on horizontal surface and the vertical plane between front vehicle frame 13 and the back vehicle frame 12 and rotates mutually.
Described articulated body front stall 1 and articulated body back seat 2 are hinged by the hinge pin axle 5 of two concentricity lines, and the length of every hinge pin axle 5 just can shorten more greatly like this.Under the identical situation of diameter because contraction in length, therefore the bearing capacity of every hinge pin axle 5 of the present invention more than or equal in the like product in the past than the bearing capacity of band andgudgeon bearing pin 5; Because the present invention has two hinge pin axles 5, thus total bearing capacity more in the past like product improve greatly.In addition, make when of the present invention, the width between centers 19 of two hinge pin axles 5 can be adjusted according to the needs that connect forward and backward vehicle frame 12, makes the model of different width between centerss.In a word, the present invention is simple in structure, and is easy to use, and four cone bearings 6 can be installed easily, improves load-carrying capacity under the prerequisite that does not increase hinge pin axle 5 diameters greatly.
Claims (2)
