摘要： A brake system for controlling a brake of a unit hauled by a vehicle, the brake system including a first pedal for braking a right rear wheel of the vehicle through a first braking circuit, a second pedal for braking a left rear wheel of the vehicle through a second braking circuit, an input line arrangement including a first input line for receiving a fluid from the first braking circuit and a second input line for receiving a fluid from the second braking circuit, at least one output line for sending a fluid to the brake of the hauled unit, and a selective connector for selectively connecting the input line arrangement to the output line by setting a first connection configuration when the vehicle has a speed greater than a threshold value and a second connection configuration when the vehicle has a speed lower than the threshold value, whereby in the first connection configuration pushing any of the pedals activates the brake of the hauled unit, and in the second connection configuration pushing only one of the pedals leaves the brake of the hauled unit inactive, so that the vehicle can be steered by braking.

摘要： A control apparatus is configured to control a brake of a unit hauled by a vehicle. The vehicle includes a plurality of brakes for braking the wheels of the vehicle, a trailer brake for braking the hauled unit, and a parking brake for keeping the vehicle braked while it is stationary. The control apparatus includes a line for sending a fluid to the trailer brake through a control valve in order to brake the hauled unit in certain working conditions, a further line for sending a further fluid to the trailer brake in order to activate the trailer brake in other working conditions, and a valve device for controlling flow of the further fluid in the further line, the valve device being responsive to a signal indicative of the status of the parking brake.

摘要： A hydraulic system for a work vehicle has a high pressure circuit for providing high pressure hydraulic fluid, a medium pressure circuit for providing medium pressure hydraulic fluid, and a low pressure hydraulic circuit for providing low pressure hydraulic fluid. The high pressure circuit has a variable displacement charge pump that provides pressurized hydraulic fluid only to a high pressure variable displacement pump according to demand, which provides the further pressurized hydraulic fluid to a priority valve according to demand. The medium pressure circuit has a medium pressure variable displacement pump that provides pressurized hydraulic fluid according to demand. The low pressure circuit has at least one low pressure variable displacement pump that provides pressurized hydraulic fluid by way of an oil cooler and/or an oil cooler bypass controlled by a proportional valve.
