Abstract
A steering hinge mechanism for an agricultural small-sized loading machine comprises a front and rear frame hinge device, a hinge connecting rod component and a steering cylinder. One end of the hinge connecting rod component is connected with a front frame hinge plate in the front and rear frame hinge device, the other end of the hinge connecting rod component is connected with a rear frame hinge plate in the front and rear frame hinge device, one end of the steering cylinder is connected with the front frame hinge plate in the front and rear frame hinge device, and the other end of the steering cylinder is connected with the rear frame hinge plate in the front and rear frame hinge device. The front frame hinge plate in the front and rear frame hinge device is fixed onto the rear frame hinge plate by a hinge shaft, a hinge ball joint and the like. Two ends of a hinge connecting rod are respectively sequentially connected with the hinge ball joint, a bolt, a washer and nuts. The steering hinge mechanism is simple in structure, convenient in processing and low in cost, has fewer repair and maintenance procedures, and is particularly suitable for small hinge type steering agricultural loading machines or similar vehicles.
Description
Technical field
The utility model belongs to the loader field, relates to a kind of small farm loader, relates in particular to a kind of small farm loading machine steering linkwork.
Background technology
At present, the articulated steering mechanism of the small farm loader that China produces mostly adopts the post hinge structure of single degree of freedom, realizes turning to through the effect that turns to oil cylinder, and the swing of swing axle or back swing axle realizes that the agricultural loader four-wheel contacts to earth before adopting.Its complex structure, amount of parts is more, and cost is higher.Adopt the swing axle frame mode, swing axle can not be rigidly connected with vehicle frame, and intensity can not get strengthening, and can cause front vehicle frame or back frame strength not enough.And because the existence of swing axle causes the gap change between vehicle frame and the tire, in order to guarantee the minimum clearance between tire and the mudwing, often make that the center of gravity of vehicle frame is higher during design, be unfavorable for reducing the stability of car load.
The utility model content
It is a kind of simple in structure, easy to process that the purpose of the utility model is to provide, and the maintenance link is few, lower-cost small farm loading machine steering linkwork.
The technical scheme of the utility model is: small farm loading machine steering linkwork comprises: front and back vehicle frame articulated mounting, articulated linkage assembly, turn to oil cylinder; Front vehicle frame articulated slab in articulated linkage assembly one end and the front and back vehicle frame articulated mounting is connected; Back vehicle frame articulated slab is connected in the articulated linkage assembly other end and the front and back vehicle frame articulated mounting; Turn to that the front vehicle frame articulated slab is connected in oil cylinder one end and the front and back vehicle frame articulated mounting, turn to that back vehicle frame articulated slab is connected in the oil cylinder other end and the front and back vehicle frame articulated mounting.
Before and after in the vehicle frame articulated mounting the front vehicle frame articulated slab, back vehicle frame plate is through jointed shaft, hinged bulb and be installed in the last spacer on the hinged bulb, following spacer, packing ring, nut, the jam nut under the hinged bulb links together, gland is fixed on hinged bulb on the back vehicle frame articulated slab through bolt.
Articulated linkage two ends in the articulated linkage assembly are connected with hinged bulb, bolt, packing ring, nut respectively successively.
The utility model can reach following good effect after adopting technique scheme: this mechanism has possessed the double freedom function, thereby one degree of freedom is by turning to oil cylinder control to realize turning to, and another degree of freedom adapts to ground-surface out-of-flat automatically.Have simple in structure, easy to process, the maintenance link few, cost is low.Be specially adapted to the agricultural loader or the similar vehicles of small-sized articulated steering.

Fig. 3 is the structure D-D cross-sectional schematic of the utility model small farm loading machine steering linkwork.
The specific embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, small farm loading machine steering linkwork comprises: front and back vehicle frame articulated mounting A, articulated linkage assembly B, turn to oil cylinder C; Front vehicle frame articulated slab 1 among articulated linkage assembly B one end and the front and back vehicle frame articulated mounting A is connected; Back vehicle frame articulated slab 2 is connected among the articulated linkage assembly B other end and the front and back vehicle frame articulated mounting A; Turn to that front vehicle frame articulated slab 1 is connected among oil cylinder C one end and the front and back vehicle frame articulated mounting A, turn to that back vehicle frame articulated slab 2 is connected among the oil cylinder C other end and the front and back vehicle frame articulated mounting A.
Before and after vehicle frame articulated mounting A, mainly comprise: front vehicle frame articulated slab 1, back vehicle frame articulated slab 2, hinged bulb 11, gland 10, bolt 9, go up spacer 8, spacer 12, packing ring 13, nut 14, jam nut 15, jointed shaft 16 down.Front vehicle frame articulated slab 1, back vehicle frame plate 2 are linked together through jointed shaft 16, hinged bulb 11 and the last spacer 8, the following spacer 12 under the hinged bulb 11, packing ring 13, nut 14, the jam nut 15 that are installed on the hinged bulb 11, and gland 10 is fixed on hinged bulb 11 afterwards on the vehicle frame articulated slab 2 through bolt 9.
Articulated linkage assembly B mainly comprises: bolt 3, articulated linkage 4, hinged bulb 11.Articulated linkage 4 two ends are connected with hinged bulb 11, bolt 3, packing ring 7, nut 6 respectively successively.
After this linkwork assembled, can possess the function of two rotational freedoms.
When turning to the loculus oil-feed of oil cylinder C, vehicle frame articulated mounting A before and after the pulling, the angle before and after making between the front vehicle frame articulated slab 1 of vehicle frame articulated mounting A and the back vehicle frame articulated slab 2 diminishes; When turning to the big chamber oil-feed of oil cylinder C, the angle before and after making between the front vehicle frame articulated slab 1 of vehicle frame articulated mounting A and the back vehicle frame articulated slab 2 becomes big, thereby realizes turning to.When ground was uneven, second degree of freedom of this mechanism adapted to ground-surface out-of-flat automatically.
Adopt the agricultural loader of this mechanism to satisfy its need of work, and simple in structure, to use reliably, the maintenance link is few, and cost is lower, is the equipped ideal product that turns to linkwork of small farm loader.
