Description
Technical field
The utility model relates to a kind of forklift steering bridge, is specifically related to a kind of forklift steering bridge with turning speed limiting mechanism.
Background technology
The horizontal hydraulic oil cylinder type steeraxle of the general employing of steeraxle of four-wheel counterbalanced lift truck, drives wheel to rotate around steering yoke bolt by the straight-line displacement of hydraulic cylinder piston rod, forms the turning of travelling of vehicle.Fork truck travels and turns is the common action of vehicle, well-known, and roll-over accident the most easily occurs vehicle in the time travelling turning, and this is mainly because vehicle has lost lateral stability in the situation that of fast running.At present, the speed of a motor vehicle control of most four-wheel counterbalanced lift trucks in the time travelling turning is operated to realize by the subjectivity of chaufeur, seldom has the mechanism that turning driving automatic speed-limiting or deceleration are installed on vehicle.Minority fork truck has been installed turning automatic speed-limiting mechanism at the right wheel place of steeraxle, mainly to produce angle induction by installing angle potential device, and transmission of signal is to controller, and then limited the moving velocity of vehicle by controller, ensure the safety that turn inside diameter travels.But the complex structure of this speed limiting mechanism, the install and adjust of corner potential device is equally very complicated, and control accuracy is also inadequate, and its reliability decrease of long duration or completely lose affects drive safety.
Utility model content
The purpose of this utility model is to provide a kind of forklift steering bridge with turning speed limiting mechanism, and this forklift steering bridge is simple in structure, easy for installation, and control accuracy is high.
For achieving the above object, the utility model has adopted following technical scheme: comprise and be arranged on approaching inductive switch and being arranged on steering cylinder piston rod and the induction support that approaches inductive switch and match on steeraxle web, described steering cylinder piston rod is connected with steering swivel by connecting rod, and described wheel is fixed on steering swivel.
The described inductive switch that approaches is fixed on steeraxle web by approaching inductive switch mounting bracket.
Described induction support is L-type, comprise the first support of fixing with steering cylinder piston rod and with approach match the second support of induction of inductive switch, the first described support is provided with is convenient to install the waist shaped hole that regulates the second support and approach gap between inductive switch.
The described inductive switch mounting bracket that approaches is U-shaped bending part, and there is wing plate at the two ends of described U-shaped bending part respectively outside horizontal-extending, and described wing plate and steeraxle web fix, and described U-shaped bending part is provided with the circular hole that fixedly approaches inductive switch.
As shown from the above technical solution, the utility model by installing respectively approaching inductive switch and responding to support of the induction that cooperatively interacts on steeraxle web and steering cylinder piston rod, respond to the variation that turns to of steeraxle with this, and limit the moving velocity of vehicle by feeding back signal to controller, simple in structure, easy for installation, control accuracy is high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model induction support;
Fig. 3 is the structural representation that the utility model approaches inductive switch mounting bracket.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
A kind of forklift steering bridge with turning speed limiting mechanism as shown in Figure 1, comprise and be arranged on approaching inductive switch 2 and being arranged on steering cylinder piston rod 3 and the induction support 4 that approaches inductive switch 2 and match on steeraxle web 1, steering cylinder piston rod 3 is connected with steering swivel 6 by connecting rod 5, and wheel 7 is fixed on steering swivel 6.
Further, approaching inductive switch 2 is fixed on steeraxle web 1 by approaching inductive switch mounting bracket 8.
Further, as shown in Figure 3, approach inductive switch mounting bracket 8 for U-shaped bending part, there is wing plate 81 at the two ends of U-shaped bending part respectively outside horizontal-extending, wing plate 81 fixes with steeraxle web 1, and U-shaped bending part is provided with the circular hole 82 that fixedly approaches inductive switch 2.
Further, as shown in Figure 2, induction support 4 is L-type, comprise the first support 41 of fixing with steering cylinder piston rod 3 and with approach match the second support 42, the first supports 41 of induction of inductive switch 2 and be provided with and be convenient to install the waist shaped hole 43 that regulates the second support 42 and approach gap between inductive switch 2.The second support 42 can change its length, to change the angular range of turning Control for Speed Limitation.
The utility model has mainly adopted the variation that turns to that approaches inductive switch and respond to steeraxle, and its principle of work is as follows:
When steering wheel for vehicle is during in meta, steering cylinder piston rod 3 is also in symmetrical position, vehicle straight-line travelling is not turned, now be fixed on the inductive switch 2 that approaches approaching on inductive switch mounting bracket 8 and face the induction support 4 being fixed on steering cylinder piston rod 3, approach inductive switch 2 and produce an induced signal, vehicle control device collects after this signal, does not change Vehicle Speed.
When chaufeur is to the left or to the right when steering wheel rotation, hydraulic oil in hydraulic circuit promotes steering cylinder piston rod 3 left or rectilinear movement to the right, the movement of steering cylinder piston rod 3 promotes connecting rod 5, steering swivel 6 again, and then band motor car wheel 7 is around steering yoke bolt rotation, forms turn inside diameter and travels.When induction support 4 is along with center position is left in 3 rectilinear movements of steering cylinder piston rod, and stroke exceedes after the half of the second support 42 length, approach inductive switch 2 and lose the induction to induction support 4, now vehicle control device collects the variable signal that approaches inductive switch 2, initiatively Vehicle Speed is reduced to restriction, until chaufeur reverse operating bearing circle, induction support 4 is again returned to and approaches inductive switch 2 and have the position of induction, vehicle control device is just cancelled the restriction to moving velocity, returns to normal speed and travels.
The utility model is that turning speed limiting mechanism has been installed at wheel place on the right, and because steeraxle has symmetrical property, therefore this turning speed limiting mechanism also can be arranged on wheel place, the left side.
The beneficial effects of the utility model are: 1) integral structure is simple, installation, easy to adjust; 2) improve induction control accuracy, improved the fiduciary level that turn inside diameter speed limit is travelled; 3) this turning speed limiting mechanism is difficult for by stained, long service life.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skill in the art make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
