Technical field
The utility model relates to a kind of steering hardware of power actuated vehicle, relates to a kind of four-wheel steering mechanism that is used for the omnidirectional running of powered industrial truck specifically and be a kind of powered industrial truck omnidirectional steering hardware.
Background technology
Along with the application of powered industrial truck such as fork truck is constantly widened, the performance requriements of its steering swivel system is more and more higher, especially in the narrow space operation, need steering swivel system can realize flexible operation functions such as little Turning radius or horizontal walking, this is that the general steering swivel system of industrial vehicle can't be realized.
The utility model content
At above-mentioned situation, the purpose of this utility model is to provide a kind of powered industrial truck steering swivel system, realizes that longitudinal driving four-wheel steering, crab row turn to, and cross running.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of powered industrial truck omnidirectional steering hardware, mainly by the storage battery that is used to provide power, electrical motor, Hydraulic Pump, hydraulic steering gear, solenoid directional control valve and front-wheel steering oil cylinder, rear-axle steering oil cylinder, turn to the sprocket wheel on the axis of revolution of chain and bonded assembly wheel to constitute; Above-mentioned storage battery is connected with electrical motor, be connected with hydraulic steering gear by pipeline by electric motor driven Hydraulic Pump, hydraulic steering gear connects solenoid directional control valve, front-wheel steering oil cylinder, rear-axle steering oil cylinder, turns to chain by turning to oil cylinder to connect driving, the sprocket wheel on the axis of revolution of chain connection wheel.
The utlity model has following advantage: rational in infrastructure, in-use performance is reliable, and control comfort is integrated with multiple steering mode, has solved the turn to problem of powered industrial truck in the flexible operation of small space.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Description of drawings
Fig. 1 is a system architecture scheme drawing of the present utility model.
Fig. 2 is a principle of work scheme drawing of the present utility model.
The specific embodiment
As Fig. 1, shown in Figure 2, a kind of powered industrial truck of the utility model omnidirectional steering hardware, main by the storage battery 12 that is used to provide power, electrical motor 6, Hydraulic Pump 7, hydraulic steering gear 8, solenoid directional control valve 11 and front-wheel steering oil cylinder 13, rear-axle steering oil cylinder 2, turn to the sprocket wheel 4 on the axis of revolution 1 of chain 3 and bonded assembly wheel 5 to constitute, wherein, storage battery 12 is connected with electrical motor 6, the Hydraulic Pump 7 that is driven by electrical motor 6 is connected with hydraulic steering gear 8 by pipeline, hydraulic steering gear 8 connects solenoid directional control valve 11, front-wheel steering oil cylinder 13, rear-axle steering oil cylinder 2, by turning to oil cylinder 2,13 connect driving turns to chain 3, the sprocket wheel 4 on the axis of revolution 1 of chain 3 connection wheels 5.
Principle of work of the present utility model is as follows:
Vertically the front two-wheeled independently connects to ground respectively, whenever takes turns identical sprocket wheel, turns to oil cylinder with messenger chain both to be connected by one, with the motion of oil cylinder piston bar, drives two-wheeled and does identical rotation; Back two-wheeled and front be symmetry fully, the direct motor drive Hydraulic Pump is sent into deflector with working medium (hydraulic oil) from hydraulic reservoir, through solenoid directional control valve and turn to oil cylinder to flow back to hydraulic reservoir through deflector again, direction of passage dish and solenoid directional control valve change and turn to advancing of oil cylinder, fuel-displaced direction, control steering oil cylinder piston rod sway, thereby Quality Initiative band movable sprocket is realized turning to of vehicle, during the longitudinal direction of car cruising, the front and back wheel counter-rotation, crab when row after turn to the adjustment of oil cylinder sense of motion, four-wheel is all rotated to same direction, realize the crab row, when corner reaches 90 when spending, whole wheel is horizontal by vertical change, get final product cross running, when solenoid directional control valve disconnected, the front-wheel steering oil cylinder was connected, the rear-axle steering oil cylinder disconnects, realize front-wheel steering, the front and back bridge is provided with two position transdusers respectively, the position of indication wheel.
Working process of the present utility model is such: electrical motor 6 drives Hydraulic Pump 7 working medium (hydraulic oil) is sent into deflector 8 from hydraulic reservoir 9 through oil filter 10, through solenoid directional control valve 11 (connecting forward or backwards) and front-wheel steering oil cylinder 13, rear-axle steering oil cylinder 2, flow back to hydraulic reservoir 9 through deflector 8 again, the direction of passage dish rotates drive deflector 8 and changes advancing of front-wheel steering oil cylinder 13 and rear-axle steering oil cylinder 2, fuel-displaced direction, control sprocket wheel oil cylinder piston bar sway, thereby control chain 3 drives sprocket wheel 4 and realizes turning to of wheel of vehicle 5, by solenoid directional control valve 11 just, oppositely connect the four-wheel steering of realizing wheel, the crab row turns to, walk crosswise and turn to, disconnection by solenoid directional control valve 11, front-wheel steering oil cylinder 13 is connected, rear-axle steering oil cylinder 2 disconnects, and realizes front-wheel steering.
The utility model is rational in infrastructure, and in-use performance is reliable, and control comfort is integrated with multiple steering mode, has solved the turn to problem of powered industrial truck in the flexible operation of small space.
In sum, be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
