Abstract
The utility model provides a novel hinge positioning structure of a loader. The novel hinge positioning structure mainly comprises an upper positioning hinge shaft and a lower positioning hinge shaft. The upper positioning hinge shaft mainly comprises an upper hinge shaft, an upper knuckle bearing and an upper support sleeve. An upper fixing plate and the upper support sleeve are disposed in the middle of the upper hinge shaft. The lower end of the upper support sleeve is pressed against a rear frame upper hinge lower plate. The upper knuckle bearing is of a fixing rotary structure. The lower portion of the upper knuckle bearing fixes the upper hinge shaft through an upper fixing pressing plate and a nut. The lower positioning hinge shaft mainly comprises a lower hinge shaft and a lower knuckle bearing. A lower fixing plate and a lower support sleeve are disposed in the middle of the lower hinge shaft. The lower knuckle bearing is of a fixing rotary structure. The lower support sleeve is directly connected with the lower fixing pressing pate. The lower end of the lower support sleeve is pressed against the lower fixing pressing plate. An adjusting pad is disposed between the lower fixing pressing plate and a rear frame lower hinge lower plate. The novel hinge positioning structure has the advantages that the upper positioning shaft and the lower positioning shaft are capable of positioning, quantitative abrasion caused by unilateral positioning is shared effectively, and the service of hinge shafts is prolonged.
Description
Technical field
The utility model belongs to technical field of engineering machinery, is specifically related to the hinged location structure of a kind of loader.
Background technology
Wheel loader is a kind ofly to take handling bulk material and be main earth moving machinery, can be widely used in the places such as the engineerings such as highway, railway, harbour, harbour, colliery, mine, goods yard, water conservancy, national defence and urban construction, configure multiple equipment and can realize the functions such as handling, excavation, fragmentation, a tractor serves several purposes.Loader front/rear frame is commonly articulated structure now, hinged location, upper end (or lower end), and the other end is generic connectivity.Wherein place, hinged location is mainly comprised of step jointed shaft, upper press cover, oscillating bearing, fixed disk, support set, nut etc., and generic connectivity place is comprised of common jointed shaft, upper press cover, oscillating bearing, lower cover etc.This structure is used for many years on loader, and shortcoming is that locating shaft wearing and tearing are comparatively serious, and the life-span is short, and dismounting difficulty after wearing and tearing, generic connectivity axle also abrasion deformation thereupon after locating shaft abrasion deformation, makes hinge portion occur loosening situation, then produces safety problem.
Summary of the invention
The utility model provides a kind of loader novel hinged location structure, to solve the problems of the technologies described above.
The utility model is mainly comprised of upper location jointed shaft and lower location jointed shaft, wherein upper location jointed shaft is mainly comprised of upper jointed shaft (Step Shaft), upper joint bearing, upper support cover, upper jointed shaft middle part arranges fixed disk and upper support cover, upper support cover lower end withstands on rear vehicle frame in hinged lower plate, upper joint bearing is fixing rotary structure, and bottom is fixed upper jointed shaft by upper fixed platen and nut; Lower location jointed shaft is mainly comprised of lower jointed shaft (Step Shaft), hypozygal bearing, lower support cover, lower jointed shaft middle part arranges lower fixed disk and lower support cover, hypozygal bearing is fixing rotary structure, lower support cover is directly connected with lower fixed platen, lower end withstands in lower fixed platen, under lower fixed platen and rear vehicle frame, between hinged lower plate, adjusting pad is set.
Preferably, in upper jointed shaft lower end and lower jointed shaft upper end, grease nipple is set respectively.
In upper jointed shaft lower end and lower jointed shaft upper end, grease nipple is set respectively, is easier to the filling of butter.
In the utility model, locate up and down jointed shaft and all can play positioning action, effectively shared the quantitative wearing that monolateral location produces, make jointed shaft life, complete machine hinged place is more firm, durable, hinged location structure works long hours continuously, and articulation steering is stable, jointed shaft abrasion condition obviously reduces, and maintenance rate declines 50%.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is upper hinged place described in the utility model structural representation;
Hinged lower plate on hinged upper plate, the hinged upper plate of 9 front frame, 10 rear vehicle frames on fixed platen, 7 nuts, 8 rear vehicle frames on fixed disk, 5 upper support covers, 6 on jointed shaft, 2 upper press covers, 3 upper joint bearings, 4 on 1 in figure.
Fig. 2 is lower hinged place described in the utility model structural representation;
Hinged lower plate under hinged upper plate, the hinged lower plate of 10 front frame, 11 rear vehicle frames under 1 time jointed shaft in figure, 2 lower covers, 3 hypozygal bearings, 4 lower fixed disks, 5 lower support covers, 6 adjusting pads, 7 times fixed platen, 8 nuts, 9 rear vehicle frames.
The specific embodiment
As shown in Figure 1, upper jointed shaft (Step Shaft) 1 middle part arranges fixed disk 4 and upper support cover 5, upper support is overlapped 5 lower end immediate roofs on rear vehicle frame in hinged lower plate 10, upper joint bearing 3 is fixed, is supported, upper joint bearing 3 is fixing rotary structure, and bottom is fixed upper jointed shaft 1 by upper fixed platen 6 and nut.
As shown in Figure 2, lower jointed shaft (Step Shaft) 1 middle part arranges lower fixed disk 4 and lower support cover 5, hypozygal bearing 3 is fixing rotary structure, lower support cover 5 is directly connected with lower fixed platen 7, lower end withstands in lower fixed platen 7, under lower fixed platen 7 and rear vehicle frame, between hinged lower plate 11, adjusting pad 6 is set, the relation under the rear vehicle frame of adjustment between hinged lower plate 11 and the hinged lower plate 10 of front frame.
As depicted in figs. 1 and 2, in upper jointed shaft lower end and lower jointed shaft upper end, grease nipple is set respectively.
Claims (2)
1. the novel hinged location structure of loader, it is characterized in that, mainly by upper location jointed shaft and lower location jointed shaft, formed, wherein upper location jointed shaft is mainly comprised of upper jointed shaft, upper joint bearing, upper support cover, upper jointed shaft middle part arranges fixed disk and upper support cover, upper support cover lower end withstands on rear vehicle frame in hinged lower plate, and upper joint bearing is fixing rotary structure, and bottom is fixed upper jointed shaft by upper fixed platen and nut; Lower location jointed shaft is mainly comprised of lower jointed shaft, hypozygal bearing, lower support cover, lower jointed shaft middle part arranges lower fixed disk and lower support cover, hypozygal bearing is fixing rotary structure, lower support cover is directly connected with lower fixed platen, lower end withstands in lower fixed platen, under lower fixed platen and rear vehicle frame, between hinged lower plate, adjusting pad is set.
