Abstract
The utility model discloses an articulated structure used for articulating the front frame and the rear frame of the vehicle, which belongs to the engineering machinery technology field. The articulated structure comprises a front frame, a rear frame and an upper articulated part and a lower articulated part of the front frame and the rear frame. The articulated structure is characterized in that an axle sleeve is fixed and arranged on the front frame of the upper articulated part, and an upper articulated pin axle is sleeved in the axle sleeve; a bearing is fixed and arranged on the rear frame of the lower articulated part, and a lower articulated pin axle is sleeved in the bearing. The articulated structure has the advantages of high bearing strength, simple structure, low production cost and convenient maintenance.
Description
Technical field
The utility model relates to technical field of engineering machinery, relates in particular to construction machinery and equipment pivotally connected frame articulated structure.
Background technology
In loader, road grader or Other Engineering machinery, be one of member of paramount importance in this body structure of vehicle as the vehicle frame that carries its deadweight and external force of gravity.Because the requirement of complete machine manoevreability, the vehicle frame of articulated vehicle does not all adopt integral type at present, but uses radial type in a large number, so the articulated structure of front vehicle frame and back vehicle frame is particularly important.Usually, the hinge point of front vehicle frame and back vehicle frame is divided into articulated section and following articulated section, and at present, generally there are two kinds of textural association forms upper and lower articulated section: one, axle sleeve is all adopted in upper and lower articulated section; Two, bearing is all adopted in upper and lower articulated section, and bearing is cone bearing or oscillating bearing.For first kind of version, loading strength is limited, and cost is low, and assembling is safeguarded inconvenience easily, generally is used for the mini engineering vehicle, and for second kind of version, loading strength is higher, the cost height, and the assembling difficulty, easy to maintenance, generally be used for large engineering vehicle.Therefore, if guaranteeing that articulated structure is simple under the vehicle frame pivotally attached intensity prerequisite, productive costs is low, and maintaining is convenient, the difficult problem that domestic and international exactly manufacturing firm faces.
Summary of the invention
The utility model is intended to propose a kind ofly can satisfy the pivotally connected frame loading strength, and simple in structure, low production cost and maintaining be vehicle frame articulated structure before and after the articulated vehicle easily.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
Vehicle frame articulated structure before and after a kind of articulated vehicle comprises the last articulated section and the following articulated section of front vehicle frame, back vehicle frame, front vehicle frame and back vehicle frame, and it is characterized in that: be fixed with axle sleeve on the front vehicle frame of articulated section on described, last hinging pin shaft is placed in the axle sleeve; Be fixed with bearing on the back vehicle frame of described articulated section down, following hinging pin shaft is placed in the described bearing.
Described bearing is through anchor bearing loam cake and following anchor bearing lower cover are fixed down.
Described bearing is the roller cone bearing.
Advantage of the present utility model is:
Because the utility model in the stressed following articulated section bigger than normal of vehicle frame, adopts the roller cone bearing, and for adopting axle sleeve structure in stressed relatively last articulated section less than normal, thereby reached the operating needs of construction machinery and equipments such as loader, and loading strength is good, assembling is simple, maintainability is good, and productive costs is low.
Description of drawings
Fig. 1 is an integral structure scheme drawing of the present utility model
Fig. 2 is the A-A sectional structure scheme drawing of Fig. 1
The specific embodiment
As shown in Figure 2: vehicle frame articulated structure before and after the articulated vehicle comprises the last articulated section and the following articulated section of front vehicle frame 1, back vehicle frame 2, front vehicle frame 1 and back vehicle frame 2 being fixed with axle sleeve 3 on the front vehicle frame 1 of described upward articulated section that last hinging pin shaft 4 is placed in the axle sleeve 3; Be fixed with bearing 5 on the back vehicle frame 2 of described articulated section down, following swivel pin axle sleeve 6 is in described bearing 5.Described bearing 5 is the roller cone bearing.Described bearing 5 is through anchor bearing loam cake 7 and following anchor bearing lower cover 9 are fixing down.
Because the utility model in the stressed following articulated section bigger than normal of vehicle frame, adopts the roller cone bearing, and for adopting axle sleeve structure in stressed relatively last articulated section less than normal, thereby reached the operating needs of construction machinery and equipments such as loader, and loading strength is good, assembling is simple, maintainability is good, and productive costs is low.
The utility model is widely used in loader, road grader and the Other Engineering machinery.
