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: A system for controlling the temperature of a charge air stream flowing through an air-cooled intercooler of a turbocharged internal combustion engine, with a fan for producing a cooling air stream acting on the intercooler and with an actuation unit for controlling the flow of cooling air as a function of charge pressure present at the intercooler.

Abstract: An exhaust gas after-treatment system includes an oxidation catalytic converter, a carbon-particulate filter, a device for burning off carbon-particulate matter within the carbon-particulate filter, and an exhaust gas cooling unit downstream of the filter for reducing the exhaust gas temperature in the exhaust gas flow. In order to reduce the fuel consumption overall, the device cooling unit can be deactivated.

Abstract: A fan assembly for an agricultural tractor includes a rotatable fan mechanically driven by a drive shaft coupled to an internal combustion engine. A fan shroud encloses the outer periphery of the fan and is mechanically connected to the engine. A bearing is mounted on the drive shaft and supports the fan shroud so that the drive shaft is rotatable with respect to the fan shroud. The bearing prevents radial and axial movement of the fan shroud relative to the drive shaft. A fan housing is connected to a radiator which is connected to the engine. The fan housing is coupled to an end of the fan shroud by a friction coupler which prevents rotation of the fan shroud.
