Patent number: 7748488Abstract: The invention relates to a steering system for an agricultural or industrial utility vehicle, especially for a tractor. An electric drive (22, 24) is provided for each half of an axle, preferably a front axle (20), of the utility vehicle (10). Said electric drive can be driven by at least one wheel (26) associated with the each axle half. The electric drive (22, 24) can be controlled in such a manner that predetermined torque can be transmitted from the electric drive (22, 24) to the wheel (26) which is being driven. Preferably, the wheels (14) associated with a mechanical drive axle, particularly a rear axle (12) of the utility vehicle (10), can be driven by a mechanical drive (16, 18) of the utility vehicle (10). The invention also relates to a method for operating a steering system.Type: GrantFiled: September 20, 2004Date of Patent: July 6, 2010Assignee: Deere & CompanyInventors: Nicolai Tarasinski, Joachim Sobotzik, Marco Reinards, Bernd Kneer

Patent number: 7584722Abstract: The invention relates to a vehicle engine system. The engine system includes an internal combustion engine, a cooler of a cooling circuit, an electric generator driven by the engine from a side of the engine which is other than that which faces the cooler, and a fan for moving air through the cooler, all disposed in an engine compartment. An electric motor is powered by the generator and mechanically drives the fan through an output shaft which is mechanically connected to the fan. The output shaft of the motor is disposed in the engine compartment near a mechanical power take-off of the engine. The mechanical power take-off includes a belt pulley connected to a free end of an engine crankshaft.Type: GrantFiled: August 3, 2007Date of Patent: September 8, 2009Assignee: Deere & CompanyInventor: Joachim Sobotzik

Publication number: 20090211682Abstract: A device (30, 30?), in particular a rotary leadthrough for a tyre-filling system, is proposed. The device (30, 301) has a rotatable body (34, 34?) and a stationary body (32, 32?) and at least one chamber (106, 108, 106?, 108?) formed between the rotatable body (34, 34?) and the stationary body (32, 32?). The at least one chamber (106, 108, 106?, 108?) is delimited by opposite boundary surfaces (48, 54, 48?, 54?) of the bodies (32, 34, 32?, 34?) and by at least two sealing means (104, 104?) guided between the boundary surfaces (48, 54, 48?, 54?). At least one duct (46, 50, 52, 56, 46?, 50?, 52?, 56?) is formed in the stationary and in the rotatable body (32, 34, 32?, 34?) and issues into the at least one chamber (106, 108, 106?, 108?) between the sealing means (104, 104?). It is proposed to use sealing means (104, 104?) which are designed as brush seals.Type: ApplicationFiled: April 18, 2006Publication date: August 27, 2009Inventor: Joachim Sobotzik

Publication number: 20080087480Abstract: The invention relates to a device for generating electrical energy for an agricultural or industrial commercial vehicle, comprising an electrical machine (18) which may be operated as a generator, which may be mechanically driven by an internal combustion engine (12) on the vehicle and which comprises a stator (22) and a rotor (20). A mechanical torque generated by the internal combustion engine (12) may be transmitted by a shaft (14, 38) to a gearbox (40) on the vehicle. The rotor (20) of the electrical machine (18) is fixed to a flywheel (16) or an output shaft (14) of the internal combustion engine (12). The rotor (20) has a hollow armature embodiment and the shaft (14, 26, 38) runs through the rotor (20). A damper (26) is provided between the internal combustion engine (12) and gearbox (40) for damping mechanical torque variations.Type: ApplicationFiled: October 10, 2005Publication date: April 17, 2008Applicant: Deere & CompanyInventors: Nicolai Tarasinski, Joachim Sobotzik, Marco Reinards, Bernd Kneer

Publication number: 20070203629Abstract: The invention relates to a vehicle axle system for agricultural or industrial utility vehicles, comprising a movably, preferably oscillatingly, mounted vehicle axle (30) to which at least two wheels (28) can be rotatably fixed. A torque tube (38) is provided, one end of which can be connected to a vehicle (10) frame (14) while the other end thereof can be joined to the vehicle axle (30) so as to support the axle suspension. An electric drive (32) by means of which at least one wheel (28) that is fixed to the vehicle axle (30) can be driven is disposed on the vehicle axle (30). The aim of the invention is to supply the electric drives (32) with electrical power via supply lines which will not be damaged in normal conditions. The inventive vehicle axle system is characterized in that electrical components (40, 42) for the electric drive (32) are provided on, preferably in, the torque tube (38).Type: ApplicationFiled: October 28, 2004Publication date: August 30, 2007Applicant: DEERE & COMPANYInventors: Nicolai Tarasinski, Joachim Sobotzik, Marco Reinards, Bernd Kneer

Said tyre pressure regulating system (10) comprises a compressed air source. The vehicle comprises an internal combustion engine (20) provided with a turbocharger (22) as a compressed air source for the tyre pressure regulating system (10). In order to obtain a sufficiently high tyre pressure and to be able to fill the tyres (16) in a relatively rapid manner, the turbocharger (22) has a variable geometry.Type: ApplicationFiled: September 10, 2004Publication date: June 28, 2007Applicant: DEERE & COMPANYInventors: Nicolai Tarasinski, Joachim Sobotzik, Bernd Kneer, Fritz Glaser

Publication number: 20050016193Abstract: A cooling system for an agricultural vehicle, such as a tractor driven by an internal combustion engine includes a main cooling system containing a coolant. The cooling system includes a sorption cooling system which includes an evaporator for evaporating a refrigerant, a sorption chamber for the sorption of the refrigerant vapor, a desorption chamber for the desorption of the refrigerant from the sorbent, and a condenser for condensing the refrigerant. An exhaust gas stream from the engine is conducted to the desorption chamber to provide the heat necessary for the desorption. The evaporator is used for additional cooling of the coolant of the main cooling system and/or for cooling a second exhaust gas stream from the engine.Type: ApplicationFiled: July 21, 2004Publication date: January 27, 2005Inventors: Nicolai Tarasinski, Joachim Sobotzik
