Patent number: 9651065Abstract: A mechanical system has a component, which is movable under friction. An oscillating micromotion (dither) is impressed upon the component, which, if necessary, is added to a non-oscillating base motion of the component. It is provided that the micromotion (without the base motion that is additional, if necessary) is faster within a period of the oscillation in the one direction and is of shorter duration than in the opposite direction (asymmetrical dither).Type: GrantFiled: May 5, 2010Date of Patent: May 16, 2017Assignee: ROBERT BOSCH GMBHInventors: Martin Zipperer, Winfried Moser, Klaus-Peter Schnelle, Steffen Schumacher, Lothar Krauter, Rene Deponte, Christof Ott

Patent number: 6852054Abstract: Two methods for operating a motor vehicle driven by an internal combustion engine (VM) and by two electrical machines (E1, E2) are proposed. The motor vehicle has a transmission (G) with two power paths (LP1, LP2) controllable independently of one another. Each power path (LP1, LP2) is coupled via a respective epicyclic gear (P1, P2) to one of the electrical machines (LP1, LP2) and to the input shaft (KW) of the transmission (G) and can be coupled via shiftable gears (1, 2, 3, 4, 5, 6, R) to the output shaft (AW) of the transmission (G). The object is to make it possible to operate the motor vehicle more efficiently. To reduce circulating mechanical power flow between the two power paths (LP1, LP2), particularly in the boost mode or upon recuperation of braking energy, the gear combination (1, 2, 3, 4, 5, 6, R) is varied, or the engine rpm is lowered, or only one electrical machine (E1, E2) is used as a generator.Type: GrantFiled: September 25, 2001Date of Patent: February 8, 2005Assignee: Robert Bosch GmbHInventors: Stefan Tumback, Klaus-Peter Schnelle

Patent number: 6811820Abstract: A friction lining for wet running consists of a fabric which can be applied to a carrier (6) and is partly impregnated with resin. In order to provide favorable friction conditions it is proposed that the porosity of the fabric (1) impregnated with resin is higher in the zone of the friction face (4) by a lower resin content in a surface layer (h) than in the remaining layer.Type: GrantFiled: October 3, 2002Date of Patent: November 2, 2004Assignees: Miba Frictec GmbH, Hexcel CorporationInventors: Klaus Dieter Löcker, Gerhard Hartner, Günter Mikolasch, Peter Schnell, Franz Maier-Lehner, Johann Oisser, Rüdiger Spaun

Patent number: 6558283Abstract: A transmission (15; 15a; 15b; 15c), in particular for motor vehicles, has two planetary gears (16; 16c, 17; 17c), whose ring gears (18; 18c, 19) are connected by a crown gear (12) to the crankshaft (11; 11a; 11c) of an internal combustion engine. Each planetary gear (16; 16c, 17) is coupled to a respective gear shaft (31, 32), on which input gear wheels (1E-5E, RE) for various gear ratios are disposed. The input gear wheels (1E-5E, RE) mesh with output gear wheels (1A-5A, RA) disposed on an output shaft (40; 40a; 40c). It is provided that each planetary gear (16; 16c, 17) be coupled with an electric machine (26, 27), and the electric machines are for instance connected to the sun wheels (23; 23a, 24; 24a) of the planetary gear (16; 16c, 17). With the arrangement described, especially for use in hybrid vehicles, relatively high total efficiency and infinitely variable gear ratios can be achieved.Type: GrantFiled: May 2, 2001Date of Patent: May 6, 2003Assignee: Robert Bosch GmbHInventor: Klaus-Peter Schnelle

Publication number: 20030005784Abstract: An apparatus is proposed for coupling at least one secondary assembly (32), in particular a starter generator, to a primary assembly (20), in particular an internal combustion engine. The at least one secondary assembly (32) and the apparatus for coupling (26) are connected to each other by means of a transmission mechanism (27). The apparatus has an epicyclic gear (38) which connects the primary assembly (20) to the transmission mechanism (27) and the epicyclic gear (38) can be switched between two multiplications by means of a first coupling (53). The first coupling (53) is a free-wheel coupling and a ring gear (50) of the epicyclic gear (38) can be immobilized in at least one rotation direction by means of a second coupling (56).Type: ApplicationFiled: March 1, 2002Publication date: January 9, 2003Inventors: Klaus-Peter Schnelle, Stefan Tumback

Patent number: 5855068Abstract: For a device for cutting plants with a cutting line (36, 38) which rotates around an axis of rotation and is wound on a reel (13), wherein a slide (16) releasably locks the reel (13) by means of a cam (26) with respect to elements which rotatingly take it along, wherein the length of the free end (37, 39) of the cutting line (36, 38) can be adjusted by unlocking the reel (13), wherein the slide (16) is displaced out of its locked position into its unlocked position by means of centrifugal force in the course of the shortening of the cutting line (36, 38), the cutting line adjustment is simplified and functionally improved in that the slide (16) is maintained in its locked position only by means of the force equilibrium of the mass support forces between its cam (26) and a detent (28) on the reel side, out of which it is displaceable by centrifugal force into its unlocked position, so that the reel (13) can rotate in respect to the cup (12), wherein the cam (26) is returned into the locked position by the massType: GrantFiled: December 12, 1996Date of Patent: January 5, 1999Assignee: Robert Bosch GmbHInventors: Guenter Zilly, Wilhelm Hepperle, Beate Eger, Albert Ruess, Klaus-Peter Schnelle, Jan P.
