  • Patent number: 11125192
    Abstract: A centrifugal air filter for an automotive system includes a plurality of single separators for setting an air flow passing therethrough in a turbulent motion and a separation area surrounding the plurality of single separators. The separation area receives particles from the air flow due to the centrifugal forces. A filter housing portion is located below a predefined or operation position for receiving particles from the air flow due to gravity, and an intake pipe is connected by an extraction line to a connecting pipe emerging on a filter housing and opening into the filter housing portion.
    Type: Grant

  • Patent number: 7806091
    Abstract: The invention relates to a cooling system for an internal combustion engine on a vehicle, preferably for an agricultural or industrial commercial vehicle. The cooling system includes a high temperature circuit and a low-temperature circuit. The high temperature circuit cools the internal combustion engine and includes at least a first cooler. The low temperature circuit cools a charge air cooler and, optionally, an oil cooler and includes at least one second cooler. The charge air cooler has at least two parts or stages. In the direction of flow of coolant in the low temperature circuit, the second cooler is connected downstream of a first part of the charge air cooler, the oil cooler and a second part of the charge air cooler. Alternatively or additionally, a further cooling circuit cools the charge air cooler and includes at least one cooler.

  • Publication number: 20090007857
    Abstract: The invention relates to a cooling system for an internal combustion engine (12) on a vehicle, preferably for an agricultural or industrial commercial vehicle, in particular, for a tractor. The cooling system (10) comprises a high temperature circuit (14) and a low-temperature circuit (20). The high temperature circuit (14) is provided for cooling the internal combustion engine (12) and comprises at least one cooler (18). The low temperature circuit (20) is provided for cooling a charge air cooler (22) and, optionally, an oil cooler (24) and comprises at least one cooler (26). The charge air cooler (22) is embodied with at least two parts or in two stages.

  • Patent number: 7322319
    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.

  • Patent number: 7047913
    Abstract: A cooling system is provided for a vehicle with an internal combustion engine. The cooling system includes a high temperature cooling circuit and a low temperature cooling circuit that is separated from the high temperature cooling circuit. The high temperature cooling circuit cools the engine and includes at least one cooler. The low temperature cooling circuit cools an oil cooler and, if necessary, a charge air cooler and includes a cooler. The oil cooler may be connected with the high temperature cooling circuit so the oil temperature may be controlled within a narrow temperature range.

  • Patent number: 5339494
    Abstract: The hinge for the hood of an agricultural tractor includes a reversing plate pivotally mounted on the vehicle body. A first hinge arm has one end coupled to the reversing plate and a second end coupled to the hood. A second hinge arm has one end coupled to the vehicle body and a second end coupled to the hood. The reversing plate is rotated by a manually-operated lever mechanism. A lock mechanism near a front end of the hood retains the hood in a closed position and releases the hood only after a first opening phase, after which the hood can be fully opened during a second opening phase. A gas spring is coupled between the vehicle body and the reversing plate. In the closed position the gas spring helps to hold the hood in the closed position. The gas spring helps to open the hood after the reversing plate is rotated by a certain amount beyond a neutral position.
