Abstract
The utility model discloses a synchronous steering device for an industrial vehicle, which is characterized in that the synchronous steering device for an industrial vehicle comprises a screw rod of a screw nut which is connected with a power mechanism of a vehicle, and a steering chain which is fixedly connected with the screw rod, wherein, the steering chain can be respectively connected with chain wheels which are respectively arranged on a rotating shaft of each wheel. Since the utility model uses a driving mechanism of the steering chain, which is formed by fixedly connecting the screw rod of a screw nut and the screw rod, the utility model has the advantages of small size, simple operation, low cost, and reliable performance.
Description
The utility model relates to a kind of synchronous steering hardware of powered industrial truck, especially relates to a kind of synchronous steering hardware that is used for powered industrial trucks such as fork truck, order-picking trucks.
At present, in industrial and mining enterprises, powered industrial truck such as fork truck, order-picking trucks etc. are absolutely necessary and produce equipment, because various machinery and equipment are more in the workshop, put mixed and disorderly, the space of travelling of vehicle is very little, and this just requires its steering flexibility with height, and existing powered industrial truck often can not meet the demands; In addition, existing powered industrial truck such as fork truck have shovel fortune dead angle in use, and these are all made troubles to production, also are unfavorable for the raising of production efficiency.For this reason, people develop the powered industrial truck of four wheel drive, mainly are to come transferring power by two-way cylinder, realizing the synchronous rotation of four-wheel, but this transferring structure exist volume big, handle defectives such as complexity, cost height.
The purpose of this utility model just is to provide a kind of steering hardware more reasonable, and its volume is little, cost is low, the synchronous steering hardware of the simple powered industrial truck of manipulation.
The purpose of this utility model can realize by following measure:
The utility model comprises the screw leading screw that is connected with vehicular power plant, turns to chain with leading screw is fixed together, turn to chain respectively be installed in each wheel axis of revolution on sprocket wheel be connected.
Actuating unit in the utility model is electrical motor or other actuating unit.
Since the utility model adopt the screw leading screw and with the design that turns to chain that leading screw is fixed together, make it to have that volume is little, simple to operate, with low cost, the advantage of dependable performance.
Accompanying drawing is a transmission device schematic diagram of the present utility model.
The utility model is done explanation in further detail below in conjunction with drawings and Examples:
As shown in the figure: the utility model comprises the screw leading screw 4,3 that is connected with vehicular power plant 5, turn to chain 13 with leading screw 3 is fixed together, turn to chain 13 respectively be installed in each wheel axis of revolution 2 on sprocket wheel 1 be connected, actuating unit 5 is an electrical motor.Screw is the screw that has spur gear wheel in the utility model, and turning to chain is roller chain, and hydraulic steering gear is the deflector that has safety valve.
Principle of work of the present utility model is as follows: give DC motor 11 power supplies by direct supply 12, DC motor 11 drives hydraulic oil pump 9, and then the hydraulic steering gear 6 that pipeline 7 links to each other with hydraulic oil pump 9 is passed through in driving, by hydraulic steering gear 6 control low-speed motors 5, drive again screw leading screw 4,3 and be connected with leading screw 3 turn to chain 13, turn to chain 13 to drive turning to synchronously of each wheel axis of revolution 2 realization four-wheel by the sprocket wheel 1 that is installed in respectively on each wheel axis of revolution 2.The working medium of hydraulic oil pump 9 derives from fuel tank 8, and the chargine line of hydraulic oil pump 9 is provided with an oil filter 10.
