The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2: 1. steering cylinder, 2. hydraulic reservoir, 3. triple valve, 4. HM Hydraulic Motor, 5. front steering oil cylinder, 6. hydraulic distributing valve, 7. hydraulic valve, 8. hoist cylinder, 9. rear steering oil cylinder, 10. electromagnetic valve, 11. limit switches, 12. three-dimensionals are turned round sub-switch.
It comprises electric system, hydraulic efficiency pressure system, inhibiting device, it is characterized in that: described electric system comprises that electromagnetic valve, three-dimensional turn round sub-switch, limit switch, and described hydraulic efficiency pressure system comprises HM Hydraulic Motor, hydraulic reservoir, distributing valve, steering cylinder, front steering oil cylinder, hydraulic valve, hoist cylinder, rear steering oil cylinder, triple valve; Described three-dimensional is turned round sub-switch and is fixed on the machine operation panel, and described hydraulic valve is fixed on the vehicle frame middle part and is connected with described electromagnetic valve, and the break-make of described hydraulic valve is turned round sub-switch to the control realization of described electromagnetic valve by described three-dimensional.Described inhibiting device and described rear steering oil cylinder be arranged in parallel, the sleeve that shifting axle is arranged in one is established in its outside, described shifting axle connects together with described rear steering oil cylinder by positioning plate, the middle part of described sleeve is provided with column, the flexible steel ball of one control shifting axle is arranged in the described column, and described steel ball is by described solenoid control.
During the work of the utility model self-propelled sprayer steering hardware, start first the driving driving engine, turn round the sub-switch position by the adjusting three-dimensional and realize turning function.Driving engine provides power for hydraulic efficiency pressure system, hydraulic pump works with hydraulic oil from hydraulic reservoir, through filter screen inhalant liquid press pump, transfer low pressure oil to high pressure oil, enter distributing valve, the hoist cylinder of leading up to carries out lifting and topples over, and one the tunnel turns to, this machine turn to except two take turns with four-wheel steering walking, also can carry out the side direction walking.Its steering hardware comprises electric system, hydraulic efficiency pressure system and an inhibiting device, and electric system is provided with three-dimensional and turns round sub-switch, electromagnetic valve and limit switch; Inhibiting device and rear steering oil cylinder be arranged in parallel, the sleeve that shifting axle is arranged in one is established in its outside, and shifting axle connects together with the rear steering oil cylinder by positioning plate, and the middle part of sleeve is provided with column, the flexible steel ball of one control shifting axle is arranged in the column, and steel ball is by solenoid control.Three interfaces of triple valve are connected with hydraulic reservoir, distributing valve, steering cylinder respectively, hydraulic valve is fixed on the middle part of vehicle frame, the above is connecting electromagnetic valve, control the electromagnetic valve action by the action of three-dimensional being turned round sub-switch, realize the break-make control of hydraulic valve, thereby realize the control of rear steering oil cylinder, reach the function of four-wheel steering and shifted laterally.When machine carries out two-wheel steering (2 ws), three-dimensional to be turned round sub-switch get to the two-wheel steering (2 ws) position, this moment, electromagnetic valve was not worked, and the P of hydraulic valve, the conducting of T hydraulic interface only have the front steering oil cylinder to carry out work, thereby realize the two-wheel steering (2 ws) function.When carrying out four-wheel steering, transfer three-dimensional and turn round sub-switch to the four-wheel steering position, this moment, limit switch and electromagnetic valve carried out work, T, the conducting of B hydraulic port with hydraulic valve, A, the conducting of P hydraulic port make rear steering oil cylinder and inhibiting device work, and rear steering oil cylinder and front steering oil cylinder are engaged under the control of hydraulic distributing valve collaborative back axle and propons and coordinate to turn to, the promotion front and rear wheel turns to, thereby realizes four-wheel steering.When carrying out shifted laterally, to turn round first sub-switch and get to four-wheel steering position adjustments trailing wheel direction, then will turn round sub-switch and get to the sidesway position, this moment, limit switch and electromagnetic valve were not worked, the P of hydraulic valve, the conducting of T hydraulic interface, only have the front steering oil cylinder to carry out work, it is consistent with the trailing wheel direction to regulate front-wheel, carries out the movement of side direction.
