Abstract
The utility model discloses a longitudinal rotational structure of a vehicle frame, which comprises hydraulic cylinders respectively arranged on both sides of the center of an articulated head, an articulated and a rotary bearing; the front end of the articulated head can be rotatably fixed on a connecting seat at the rear end of a front frame; the rotary bearing is circular and comprises an inner ring and an outer ring, wherein the inner ring and the outer ring are fixed via a clipping structure on the outer edge and a ball bearing in a clipping manner; and the rear end of the articulated head is fixed on the inner ring of the rotary bearing, and the outer ring of the rotary bearing is fixed on the front end of a rear vehicle frame. The utility model has the advantages of portable and flexible rotation, small friction, convenient lubricating, easy assembly and disassembly, high reliability, and good interchangeability; on the processing aspect, the requirements to the equipment, the processing process and the processing capability of the processing worker are all low, so that the production cost is further reduced, and the use and maintenance cost are reduced as well; and the longitudinal rotational structure is particularly suitable for the bumpy roads with rough and uneven ground surfaces.
Description
One, technical field
The utility model relates to the vertical rotational structure of a kind of vehicle frame.
Two, background technology
The vertical rotational structure of existing vehicle frame has two kinds: a kind of is the swing span structure, and a kind of is the cartridge type rotational structure.The swing rack and panel construction is that swing span is installed on bridge, and swing span adopts bearing pin to be connected with vehicle frame, and in the vehicle ' process, bridge lands to guarantee tire along with the bearing pin swing of swing span top, and there is structural arrangement inconvenience in the swing span structure, the shortcoming that center of gravity is high.The cartridge type rotational structure is used for articulated vehicle more, hinge portion is referred to as articulated joint in the middle of it, turn to by Driven by Hydraulic Cylinder when turning to, hinged first end and front vehicle frame are rigidly connected, the other end adopts inside and outside core structure to be connected with the back vehicle frame, adopt copper sheathing or nylon jacket transition in the middle of the core structure, by relatively rotating of inside and outside tube, before and after making bridge in the process of moving four-wheel land.The transition material of cartridge type rotational structure is easy to wear, causes cartridge type rotational structure tolerance clearance big after the wearing and tearing, and structural strength weakens, and dismounting inconvenience, and maintenance in the open air is difficulty very; In processing, processing technology is required high, Fabricating machinery is required high, processing workman's working ability is required high, so its productive costs is very high, and the cost that uses, safeguards is also very high.
Three, summary of the invention
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provides a kind of friction little, wear-resistant, easy to assemble, reliability height, the vertical rotational structure of the vehicle frame that interchangeability is good.
For achieving the above object, technical solution of the present utility model is: the vertical rotational structure of a kind of vehicle frame, and it comprises hydraulic actuating cylinder, articulated joint and the pivoting support that splits in both sides, articulated joint center; Hydraulic cylinder body is fixed on the front vehicle frame, and its piston rod is fixed in the articulated joint; The articulated joint front end rotatably is fixed on the Connection Block of front vehicle frame rear end; Pivoting support is a circle, is made up of inside and outside circle, and inner ring and outer ring are by the interface arrangment and the ball bearing of main shaft chucking maintenance of its outer rim; The articulated joint rear end is fixed on the pivoting support inner ring, and the pivoting support outer ring is fixed on the front end of back vehicle frame.
The utility model is vehicle frame center hinge contact with the articulated joint, realizes the left and right vehicle wheel handling maneuver under the effect of two hydraulic actuating cylinders.Connecting articulated joint with pivoting support, make it satisfy the vertically function of rotation of vehicle frame, its vertical maximum anglec of rotation reaches ± and 20 °, reach the purpose that four-wheel lands.The utility model has the rotation light and flexible with the frame mode of the pivoting support version replacement steel bushing/copper sheathing combination in the past of bearing type, and it is little to rub, convenient lubricated, easy to assemble, reliability height, the advantage that interchangeability is good.In processing, low for equipment requirements, processing technology requires low, and is low to processing workman's working ability requirement, and then productive costs is low, and the cost of its working service is also very low.It is rough and uneven in surface that the utility model is specially adapted to the face of land, the road conditions of jolting and rising and falling.
Four, description of drawings
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a front view of the present utility model;
Fig. 2 is a birds-eye view of the present utility model;
Fig. 3 is the AA cutaway view of Fig. 2.
Five, the specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, present embodiment comprises hydraulic actuating cylinder 5, articulated joint 3 and the pivoting support 6 that splits in both sides, articulated joint center.Hydraulic actuating cylinder 5 cylinder bodies are fixed on the front vehicle frame 1, and its piston rod is fixed in the articulated joint 3.Articulated joint 3 front ends insert in the Connection Block 11 of front vehicle frame 1 rear end, and are fixing by steering yoke bolt 2 rotations.Pivoting support 6 is a circle, is made up of inside and outside circle 10,8, and inner ring 10 and outer ring 8 are by the interface arrangment and the ball bearing of main shaft chucking maintenance of its outer rim.There is fixing structure articulated joint 3 rear ends, cooperate with the inner ring 10 of pivoting support, are connected fastening with pivoting support inner ring 10 it by bolt 7; The front end of back vehicle frame 4 has fixing structure, cooperates with pivoting support outer ring 8, pivoting support outer ring 8 is fixed on the front end of back vehicle frame 4 by bolt 9.
