Patent number: 9109970Abstract: A method for circuit separation testing in a double gearwheel pump having two gearwheel pumps includes charging one of the two gearwheel pumps with pressure and measuring the pressure build-up in the charged gearwheel pump and/or the pressure-build up in the other gearwheel pump. The pressure build-up is preferably realized by the gearwheel pump itself. The gearwheel pumps have a common pump shaft and are preferably configured as hydraulic pumps of a hydraulic vehicle brake system with slip control. The method detects any leak at the leadthrough of the pump shaft through a partition wall between the two gearwheel pumps.Type: GrantFiled: January 31, 2011Date of Patent: August 18, 2015Assignee: Robert Bosch GmbHInventors: Georg Blosch, Norbert Alaze

Patent number: 6806602Abstract: The invention relates to an electromechanical wheel brake device, with an electric motor that can press a frictional brake lining against a brake body (brake disk) by a reduction gear (planetary gear) and a rotation/translation conversion gear (ball screw). The invention proposes embodying the electric motor as a transverse flux motor with three phase windings; each phrase winding has a circular, annular excitation winding that is disposed inside U-shaped yokes, which are distributed over the circumference of the excitation winding. This embodiment of the electric motor permits a compact design of the electric motor in an annular, hollow shaft design so that the reduction gear and the rotation/translation conversion gear can be disposed at least partially inside the electric motor.Type: GrantFiled: February 10, 2003Date of Patent: October 19, 2004Assignee: Robert Bosch GmbHInventors: Juergen Hilzinger, Frank Schumann, Georg Blosch, Guenter Kastinger

Publication number: 20040036370Abstract: The invention relates to an electromechanical wheel brake device (10), with an electric motor (18) that can press a frictional brake lining (14) against a brake body (16) (brake disk) by means of a reduction gear (34) (planetary gear) and a rotation/translation conversion gear (48) (ball screw). The invention proposes embodying the electric motor (18) as a transverse flux motor (18) with three phase windings (21); each phase winding (21) has a circular, annular excitation winding (22) that is disposed inside U-shaped yokes (24), which are distributed over the circumference of the excitation winding (22). This embodiment of the electric motor (18) permits a compact design of the electric motor (18) in an annular, hollow shaft design so that the reduction gear (34) and the rotation/translation conversion gear (48) can be disposed at least partially inside the electric motor (18).Type: ApplicationFiled: February 10, 2003Publication date: February 26, 2004Inventors: Juergen Hilzinger, Frank Schumann, Georg Blosch, Guenter Kastinger

Patent number: 6428118Abstract: An arrangement for avoiding rollovers when accelerating motor vehicles, single-track or double-track vehicles such as motorcycles or passenger cars in particular, with an arrangement for comparing a difference in rotational speed between the speed of at least one front wheel or the front axle and the speed of at least one rear wheel or the rear axle of the motor vehicle with an adjustable rotational speed difference threshold value. Also included is an arrangement for detecting a wheel acceleration for at least one front wheel and for at least one rear wheel and an arrangement for activating the vehicle's propulsion system when the rotational speed difference threshold value is reached or exceeded if the wheel acceleration is simultaneously negative for at least one front wheel and positive for at least one rear wheel.Type: GrantFiled: September 29, 1999Date of Patent: August 6, 2002Assignee: Robert Bosch GmbHInventor: Georg Blosch

Patent number: 6173820Abstract: The invention relates to a brake apparatus with an electric service motor, which serves to actuate the brake via an actuating device. To enable setting an air clearance, the apparatus includes a readjuster for setting the air clearance, the brake is actuated with the readjuster and then reversed by a defined length. To realize a parking braking function, the apparatus includes a parking brake that can be repositioned from a released position to a braking position and that acts on the actuating device.Type: GrantFiled: December 9, 1999Date of Patent: January 16, 2001Assignee: Robert Bosch GmbHInventors: Georg Blosch, Dieter Blattert

Patent number: 6012556Abstract: The invention relates to a braking apparatus having an electric service motor, which serves to actuate a brake via an actuating device. To enable adjusting an air clearance, the invention sets forth a helical gear and a load moment block, which blocks the helical gear against adjusting itself independently and allows adjustment by means of a readjusting motor. To adjust or establish the air clearance, the brake is actuated with the readjusting motor, until a brake lining contacts a brake body, such as a brake disk, and then moves backward by a defined distance. If the service motor and/or the actuating device fails, the braking apparatus can be released with the readjusting motor. In order to achieve a parking brake function, the invention sets forth a second load moment block for the actuating device.Type: GrantFiled: December 29, 1997Date of Patent: January 11, 2000Assignee: Robert Bosch GmbHInventors: Georg Blosch, Frieder Keller

Patent number: 5979613Abstract: A drum brake for use in a brake system (10) having first (14) and second (16) shoes retained on a backing plate (20). The first brake shoe (14) has a first end (22) connected to an actuator (12) and a second end (26) connected to an anchor arrangement (24) and the second brake shoe (16) has a first end (36) connected to the actuator (12) and a second end (38) connected to the anchor arrangement (24) The actuator (12) responds to an input signal during a brake application by moving the first (14) and second (16) brake shoes into engagement with a drum (18). The anchor arrangement (24) includes a load sensor (64) for measuring a torque generated between the first (14) and second (16) brake shoes and the drum (18).
