Patent number: 10682996Abstract: The electromechanical brake force booster for a vehicle brake system comprises a drive arrangement for driving at least one actuating device which is designed for actuating a brake cylinder. The drive arrangement has at least one electric motor and a gearing for coupling the electric motor to the at least one actuating device. The gearing comprises at least one second spur gear and at least one first spur gear. Furthermore, the gearing has an intermediate gearing stage. The intermediate gearing stage couples the electric motor to the second spur gear and to the first spur gear in torque-transmitting fashion. The intermediate gearing stage drives the second spur gear directly and the first spur gear via at least one intermediate gear.Type: GrantFiled: September 16, 2016Date of Patent: June 16, 2020Assignees: ZF Active Safety GmbH, ZF Friedrichshafen AGInventors: Kurt Wingender, Martin Hofmann, Boris Koeth, Jose Manuel Calvo Martinez, Jens Sparfeld, Stefan Kammers, Paul Warkentin, Ingo Decker, Klemens Humm, Detlef Baasch

Patent number: 9260097Abstract: A vacuum brake servo includes a force input element, a control valve actuated by the force input element, a vacuum chamber connected to a vacuum source, and an operating chamber which, depending on the actuation of the force input element, can be connected to either the vacuum chamber or the surrounding atmosphere. The control valve has a control piston that can be actuated by the force input element and, together with a valve element, forms a seal seat having a seal seat diameter between the operating chamber and the surrounding atmosphere. In the area close to the seal seat, a guide channel is provided. When the seal seat is opened, air from the surrounding atmosphere flows into the operating chamber. The guide channel extends axially with a constant flow diameter over a predetermined length, wherein the flow diameter is less than or equal to the seal seat diameter.Type: GrantFiled: October 21, 2010Date of Patent: February 16, 2016Assignee: Lucas Automotive GmbHInventors: José Manuel Calvo Martinez, Jens Sparfeld, Detlev Knigge, Ulrich Zinnkann

Publication number: 20120227579Abstract: The invention relates to a vacuum brake servo for a motor vehicle braking system, comprising a rod-like force input element which is coupled or can be coupled to a brake pedal, a control valve which is actuated by means of the force input element, a chamber arrangement having a vacuum chamber which can be connected to a vacuum source, and also having an operating chamber which, depending on the actuation of the force input element, can optionally be connected to the vacuum chamber and to the surrounding atmosphere. The control valve has a control piston that can be actuated by means of the force input element and, together with a valve element, forms a seal seat having a seal seat diameter between the operating chamber and the surrounding atmosphere. In the area close to the seal seat, a guide channel is provided, through which, when the seal seat is opened, air from the surrounding atmosphere flows into the operating chamber as a result of a pressure difference.Type: ApplicationFiled: October 21, 2010Publication date: September 13, 2012Applicant: LUCAS AUTOMOTIVE GMBHInventors: José Manuel Calvo Martinez, Jens Sparfeld, Detlev Knigge, Ulrich Zinnkann
