摘要： An articulated work vehicle with linked front and rear frames includes a joystick lever, a force imparting component, and a controller. The joystick lever can be moved to an inside or an outside with respect to an operator's seat by being operated by an operator, to change a steering angle of the front frame with respect to the rear frame. The force imparting component is configured to impart an assist force or a counterforce to an operation of the joystick lever by the operator. The controller controls the force imparting component so that an operating force required to move the joystick lever to the outside is different from an operating force required to move the joystick lever to the inside.

摘要： A steering system includes a user-manipulable steering control, a steering actuator, a pump, and a first valve assembly configured to control a flow of fluid from the pump to the steering actuator in response to manipulation of the steering control. The steering system also includes a rotary device coupled to the steering control. The rotary device is configured to direct fluid in response to manipulation of the steering control. The steering system further includes a second valve assembly movable between a first position in which the rotary device is not in fluid communication with the steering actuator and a second position in which the second valve assembly fluidly communicates the rotary device with the steering actuator.

摘要： A hydraulic traction system for vehicles is described. The system comprises a hydraulic vane motor mounted at each wheel of the vehicle, and equal number of identical hydraulic vane motors operated as engine driven pumps, and a control system for regulating the flow and direction of hydraulic oil during operation. The hydraulic motor is of a novel design that has a hollow non-drive shaft that accepts incoming hydraulic oil, this allows internal components of the hydraulic motor to be arranged in such a way to improve the efficiency of the hydraulic traction system.

The first and second arms have tie rod mounting portions to which the tie rod is mounted. At least one of the first and second arms has a first hydraulic actuator mounting portion to which one of the cylinder and the piston in the hydraulic actuator is mounted. The third arm has a second hydraulic actuator mounting portion to which the other of the cylinder and the piston in the hydraulic actuator is mounted. The first hydraulic actuator mounting portion is at a longer distance from axis lines of the differential yoke shafts than the second hydraulic actuator mounting portion in a plan view when the vehicle is traveling substantially straight.

摘要： A hydraulic shutoff device in the end positions of a servo cylinder is provided to prevent direct hard contact between the working piston (31) and the limit stops (47, 48) under working pressure and to enable withdrawal from end positions with hydraulic assistance. Idler pistons (32, 33) with limited displaceability are located on the working piston (31) and act as a seal, fitting tightly against the sealing edges (34, 35) of the working piston. The sealing edges (34, 35) control a bypass channel (36) located in the working piston (31). A spring (41) is inserted between the idler pistons (32, 33) in a chamber (40) which can be pressurized. When the working piston (31) comes into contact, for instance, with the limit stop (48) of the bush (43), the collar (45) knocks one idler piston (33) away from the sealing edge (35). Junction with the chamber (40) occurs through the bypass channel (36), whereupon the working pressure pushes the idler piston (32) back against the spring (41) away from its sealing edge (34). The working pressure can then drop between the pressurized pressure chamber (37) and the pressure chamber (38) until the spring (41) seals the idler piston (33) against the sealing edge (34) once again. The pressure which is thus adjusted in the pressure chamber (37) holds the working piston (31) together with the idler piston (32, 33) in the end position. The pressure thus adjusted is, however, below its maximum value.
