Title: Steering device for working vehicle
Inventor: KISHIDA HIROSHI
IPC: A01B69/00
Filed: 1990-02-22
Abstract: PURPOSE:To turn a working vehicle quickly and smoothly without causing the bad condition of a clutch by intermittently switching a two-position selector valve in such a state that it is switched to a drainage condition during a preset time on detecting that a hydraulic cylinder reaches the stroke end. CONSTITUTION:When a clutch disconnect operation command for one clutch is given, a control means C switches a three-position selector valve 17 to the pressure oil supply condition in a designated direction and supplies pressure oil to designated hydraulic cylinders 13L, 13R. The start of supplying pressure oil causes the cylinders 13L, 13R to contract, whereby steering clutches 12L, 12R are disconnected. Just after that, the cylinders 13L, 13R reaches the stroke end, and when the reach is detected by a sensor 20, the control means C switches a two-position selector valve 19 to the drainage condition and maintains the drainage condition extending over a preset time. After the lapse of the preset time, the control means C switches the selector valve 19 to the drainage stop condition, and supplies pressure oil to the designated cylinders 13L, 13R again. The above switching operation of the selector valve 19 is repeated until a clutch disconnect command is cancelled.

The amount of the recirculation thereof is determined by the opening area of the valve 8 and the pressure difference between the fore part and the hind part of the valve while the amount of suction air is determined by the opening area of a throttle valve 4 and the pressure difference between the fore part and the hind part of the valve. On the other hand, in the EGR control valve 11 controlling the flow amount of the choked section 6, the valve element 18 thereof is moved to control the pressure in the pressure chamber 7 so that the pressure difference between an EGR gas chamber 13 and a vacuum chamber 14 is balanced with a constant value determined by the effective area of a diaphragm 12 and the initial load of a spring 15. When a suction pressure becomes lower than the predetermined value thereof , a check valve 28 shuts off the atmosphere and closes the EGR control valve 11 to stop the exhaust gas recirculation.
