Patent number: 10889270Abstract: Differentials having plate packs for exerting a braking torque onto the output shafts of the gear unit are known. The brake device is intended to be designed such that effective braking can be achieved using it and that it is easy to service. To this end, the invention makes provision for the brake device to be a drum brake having a passive element, exhibiting a cylindrical frictional surface, and brake shoes, the frictional surfaces of which brake shoes can be placed against the cylindrical frictional surface of the passive element. The passive element can be a brake drum or a radial brake disk, the cylindrical edge of which serves as a frictional surface. The passive element is fastened to the differential cage and/or one of the shafts. The brake shoes are held in a pivotable manner on a carrier plate fastened to the outside of the differential housing.Type: GrantFiled: August 8, 2017Date of Patent: January 12, 2021Assignee: Continental Teves AG & Co. oHGInventors: Ulrike Meyer, Martin Semsch, Uwe Bach, Jens Hoffmann, Ahmed Sefo, Wolfgang Ritter, Martin Gädke, Holger von Hayn, Adrian Messner

Publication number: 20190092298Abstract: A braking device for a hydraulic motor vehicle braking system having an electromechanically driven booster stage and a ball screw drive. In order to provide a braking device which is of particularly compact, cost-effective and weight-saving construction and has short pedal strokes, and an easily adjustable pedal characteristic curve, at the same time enabling effective direct action in case of failure of the booster stage and comfortable haptic feedback at the pedal during normal operation, the actuating force from a piston rod is introduced into the spindle, wherein the piston rod can be moved axially to a limited extent relative to the spindle and a spring element is inserted in the flow of force of the actuating force between the piston rod and the spindle, which spring is compressed axially when the actuating force is introduced.Type: ApplicationFiled: May 11, 2017Publication date: March 28, 2019Inventors: Uwe Bach, Jens Hoffmann, Martin Gädke, Holger von Hayn, Ahmed Sefo, Adrian Messner, Wolfgang Ritter

Patent number: 10151365Abstract: An expanding device for actuating one of the brake shoes of a drum brake includes a body of revolution and transmission bodies actuated by the body of revolution via ball track ramps. A spacer body is located between two partial bodies of the body of revolution, the spacer body guided by an adjustment spring keeping the partial bodies at the respectively reached distance. The spacer body is screwed onto a pin on the first partial body. A readjustment nut ensures that, when the two partial bodies are pushed apart, the spacer body rotates on the pin and moves away from a supporting surface on a partition of the second partial body. Upon renewed actuation of the brakes, the readjustment nut is guided such that the spacer body bears against the second partial body, but takes up a different position on the pin, the position corresponding to the air clearance readjustment.Type: GrantFiled: December 14, 2015Date of Patent: December 11, 2018Assignee: Continental Teves AG & Co. oHGInventors: Uwe Bach, Jens Hoffmann, Martin Gädke, Holger von Hayn, Ahmed Sefo, Thorsten Lahr, Wolfgang Ritter
