Patent number: 8635002Abstract: A method of controlling at least one coupling in a powertrain of a motor vehicle includes the steps of: determining at least one slip value which represents an instantaneous slip between different axles of the motor vehicle or between different wheels of an axle; forming an absolute value of the slip value which corresponds to the amount of the slip value; summing the absolute value or a substitute value derived therefrom to a last-formed slip sum value to form an instantaneous slip sum value; comparing the instantaneous slip sum value with a slip sum threshold value: and generating a control signal for actuating the coupling if the instantaneous slip sum value reaches or exceeds the slip sum threshold value.Type: GrantFiled: February 27, 2012Date of Patent: January 21, 2014Assignee: Engineering Center Steyr GmbH & Co KGInventors: Christoph Brenner, Gerhard Frühwirth

Patent number: 7604562Abstract: A drive axle for a light vehicle includes a chain drive and a differential, which comprises a differential cage (2) with a long neck (6, 7) at both sides, balance pinion gears (13) and two axle pinion gears (16), with the axle pinion gears (16) being journaled radially and axially in the differential cage (2). Proximal ends of axle shafts (21, 22) are plugged in the axle pinion gears (16) and at the distal ends of the necks (6, 7) in radial bearings (19) of the differential cage (2) and are supported further outwardly in a fixed bearing (33, 34) connected to the vehicle. The axle pinion gears (16) have conical parts (17) at their rear side remote from the balance pinion gears (13) and can cooperate with a conical inner wall of the differential cage (2).Type: GrantFiled: August 31, 2006Date of Patent: October 20, 2009Assignee: Engineering Center Steyr GmbH & Co.

Patent number: 7588512Abstract: A drive axle for a light vehicle having a chain drive and a differential is provided, wherein the axle pinion gears (11, 12) are connected to their half-axles (6, 7) in one piece and to the vehicle via fixed bearings (8, 8?). One of the half-axles (6) is made as a tube which receives an inner shaft (13) in a journaled manner which is fixedly plugged in the other half-axle (7). The differential cage (22, 22?) is partly spherical and surrounds the balance pinion gears (20) and is fixedly connected to a chain sprocket (25). The differential cage comprises two symmetrical shells (22, 22?) between which the chain sprocket (25) is directly fastened to the balance pins.Type: GrantFiled: September 26, 2006Date of Patent: September 15, 2009Assignee: Engineering Center Steyr GmbH & Co.

Patent number: 7559259Abstract: A method is provided for the determination of a torque which is transmitted along a torque transmission path which extends at least along a shaft of a motor vehicle. A rotary position signal is produced by a first speed of rotation sensor at a first section of the transmission path and a rotary position signal is produced by a second speed of rotation sensor at a second section of the transmission path. At a point in time at which a known torque is transmitted along the transmission path, a first rotary position signal relationship is determined with reference to the instantaneously generated rotary position signals, the rotary position signal relationship serving as an offset value. At a later point in time, a second rotary position signal relationship is determined with reference to the instantaneously generated rotary position signals. The transmitted torque is calculated on the basis of the offset value and of the second determined rotary position signal relationship.Type: GrantFiled: June 13, 2007Date of Patent: July 14, 2009Assignee: Engineering Center Steyr GmbH & Co.
