Abstract: A hydraulic system for an agricultural vehicle is proposed. The hydraulic system comprises a main hydraulic circuit, which is fed with hydraulic fluid by a main hydraulic pump, a variable displacement charge pump which supplies charge pressure to the main hydraulic pump, and a lubricating hydraulic circuits. In order to keep efficiency losses on the vehicle to a minimum, particularly at high engine speeds, part of the hydraulic fluid delivered by the charge pump can be diverted to the lubricating hydraulic circuit.

Abstract: The invention concerns a tire pressure adjusting system for setting the pressure in a tire mounted on a vehicle. A pressure source assigned to the vehicle and at least one connecting line are provided, with which the pressure source can be connected to a tire. The tire can be mounted on a rim. Within the space formed between the tire and the rim, a dividing means is provided, with which the space can be divided into two chambers. In order to reduce the time period for a change in the tire pressure, a means of limitation be provided, with which the volume expansion of a chamber can be limited to a maximum volume value that can be set, and that to change the pressure of the tire only the pressure in one of the two chambers needs to be changed.

Abstract: A vehicle braking system includes a wheel braking unit with an actuator, friction unit, and resilient member. The wheel braking unit is controlled by an operating element. The braking system can be operated in a normal operation mode by a control parameter. The braking system can be operated in a safety mode when the control parameter falls below a threshold value. In the normal mode, the control parameter acts on the actuator so that the actuator establishes a first air clearance in the friction unit. When in the safety mode, a resilient member establishes a second air clearance, which is smaller than the first air clearance.

Abstract: The present invention relates to an apparatus for coupling an implement to a working vehicle, having two lower link bars, a length-adjustable upper link bar, and two lifting elements. The end closest to the working vehicle, of each of the lower link bars and the upper link bar, is swingably mountable, and the other end closest to the implement is likewise swingably mountable. The upper link bar is essentially disposed centrally in the upper region of the coupling apparatus. The two lower link bars are disposed essentially laterally in the lower region of the coupling apparatus. One end of each of the lifting elements can be swingably mounted on a respective lower link bar. A supported load from the implement which acts on the working vehicle does not lead to diminishment of the load on a vehicle axle. For this purpose, the coupling apparatus is characterized in that the respective other ends of the lifting elements directed toward the implement, can be swingably mounted in essentially an upper region of the coupling apparatus.

Abstract: A control system controls a three point implement hitch assembly of a tractor. The three point implement hitch assembly includes an upper link and two lower links. The upper link includes an adjustable length double acting hydraulic unit. The position of each lower link is controlled by an adjustable length double acting hydraulic unit. A hydraulic circuit controls communication between the hydraulic units, a hydraulic supply and a hydraulic tank. The circuit permits each hydraulic unit to be controlled independently of one another.

Abstract: The invention concerns a steering and braking system for a motor vehicle which has wheels on opposite sides thereof. Each wheel has a brake unit that can be controlled by an operator actuating a brake device, such as a brake pedal. At least one of the brake units is controlled in response to a turning maneuver of the motor vehicle independent of the actuation of the brake pedal, so that a higher braking force is applied to an inside one of the brake units with respect to the curve than is applied to an outside one of the brake units with respect to the curve.
