Detailed description of the invention
For understanding content of the present utility model further, in conjunction with the accompanying drawings and embodiments the utility model is described in detail.
Embodiment 1
Composition graphs 1 and Fig. 2, a kind of fluid control steering hardware of the present embodiment, comprises crossbeam 1, supporting leg 2, axle sleeve 3, Linkage steering 6 and hydraulic actuating cylinder 7, and described supporting leg 2 lower end is provided with wheel, and this wheel can pass through fluid motor-driven, to reduce integral structure.In supporting leg 2 upper end, fulcrum 4 is housed, this fulcrum 4 is fixedly connected with supporting leg 2, and when fulcrum 4 rotates, supporting leg 2 can synchronous axial system.In the present embodiment, fulcrum 4 is vertically arranged on the downside of crossbeam 1 by axle sleeve 3, and axle sleeve 3 is fixed on crossbeam 1, and fulcrum 4 and axle sleeve 3 are rotationally connected, then wheel can rotate relative to crossbeam 1.
Routine arranges middle steering driving mechanism and is mostly laterally fixing, and driver train must depart from certain distance with face, wheel fulcrum place, otherwise cannot Direct driver.And in the present embodiment, hydraulic actuating cylinder 7 is fixed on crossbeam 1, and when hydraulic actuating cylinder 7 installation direction does not rotate with wheel, direction is identical, is hinged with Linkage steering 6 at the telescopic end of hydraulic actuating cylinder 7, this Linkage steering 6 other end and fork 5 hinged, this fork 5 is fixed on fulcrum 4.This mechanism can directly be stretched by the piston rod of Hydraulic Elements hydraulic control cylinder 7, without the need to other bracing or strutting arrangements, greatly reduces parts, simplifies housing construction, alleviate body weight.
During agricultural machinery running, larger Turning radius will cause large stretch of crop to be damaged by pressure, in order to reduce Turning radius, just need to increase steering angle, therefore the Linkage steering 6 in the present embodiment is arranged to primarily of one section 61, connecting rod and two section 62, connecting rod composition, as shown in Figure 2, the end that connecting rod is a section 61 and fork 5 hinged, the piston rod of the end that connecting rod is two section 62 and hydraulic actuating cylinder 7 is hinged, and the angle between one section 61, connecting rod and two section 62, connecting rod is 130 ~ 150 °.When angle is less, such as 90 °, connecting rod becomes the arm of force for two section 62 completely, and the starting stage is difficult to transmit larger power, even can be stuck; When angle is larger, due to hydraulic actuating cylinder 7 and fulcrum 4 on the same line, larger turn to thrust although can transmit, angle range is less, otherwise Linkage steering 6 can be interfered with fulcrum 4, and steering hardware is destroyed.Preferably, this angle can be selected to be 135 °.
What deserves to be explained is, when wheel does not turn to, the hinge-point of one section 61, connecting rod and fork 5 is between two section 62, connecting rod and fulcrum 4, and namely the initial position of fork 5 is partial to the left side of fulcrum 4.Because within the scope of the rise of piston rod, Linkage steering 6 is rotating to be limited in scope, if its hinge-point is positioned on the right side of fulcrum 4, the swingable scope of fork 5 is less, can not realize the object increasing angle range.
Embodiment 2
A kind of fluid control steering hardware of the present embodiment, its basic structure is identical with embodiment 1, and its difference is: the angle in the present embodiment between one section 61, connecting rod and two section 62, connecting rod is 145 °, when not turning to, and one section 61, connecting rod is parallel with crossbeam 1.In the initial steer stage, because fork 5 longitudinal travel when rotating near the lateral cross section position crossing fulcrum 4 is less, parallel structure design more contributes to the simplification of structure.
Embodiment 3
A kind of fluid control steering hardware of the present embodiment, its basic structure is identical with embodiment 2, its difference is: in the present embodiment, the length of one section 61, connecting rod is not less than the length of fork 5, makes fork 5 have larger slewing area on the right side of fulcrum 4, increases angle range.
The present embodiment additionally provides a kind of from walking agricultural machinery, and four wheel shafts of this agricultural machinery are by fluid motor-driven, and four wheel places are all provided with above-mentioned fluid control steering hardware.
Not only course changing control precision is high for scheme of the present utility model, by this steering hardware, reduces Turning radius, enormously simplify the physical construction of agricultural machinery, alleviates agricultural machinery weight, decreases the damage to crops, be convenient to promote the use of when travelling in farmland.
Schematically above be described the utility model and embodiment thereof, this description does not have restricted, and also just one of the embodiment of the present utility model shown in accompanying drawing, actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from the utility model and creating aim, design the frame mode similar to this technical scheme and embodiment without creationary, protection domain of the present utility model all should be belonged to.
