Abstract: The present invention has a purpose of improving mountability of a brake system capable of performing slip control operation of a front wheel and a rear wheel to a motorcycle. The present invention further has a purpose of obtaining a motorcycle that includes such a brake system. In a front-wheel braking section (20), a friction force, which is applied to a front wheel (3) by a first friction application device (21), varies according to a hydraulic pressure of a brake fluid in a master cylinder (22) during service braking and varies by control of a hydraulic pressure adjustment mechanism (32, 33, 36, and the like) by a controller (60) during the slip control operation. In a rear-wheel braking section (40), a friction force, which is applied to a rear wheel (4) by a second friction application device (50), varies by control of an actuator (41) by the controller (60) during the service braking and during the slip control operation.

Abstract: An arrangement for throttling a fluid flow includes a throttle element arranged so as to influence a flow cross section in a fluid duct. The throttle element has a resiliently elastic disc-shaped basic body which is arranged with a top side and a bottom side between at least two supports in the fluid duct. The body is arranged in such a way that the flow cross section can be variably adjusted as a function of a pressure difference between the top side and the bottom side of the resiliently elastic disc-shaped basic body. At least one support bears against the top side of the resiliently elastic disc-shaped basic body, and at least one support bears against the bottom side of the resiliently elastic disc-shaped basic body.

Abstract: In a hydraulic unit of a vehicle brake system having a first pump element, which is assigned to a first brake circuit, and a second pump element, which is assigned to a second brake circuit, the second pump element has a different delivery from the first pump element.

Abstract: A spring element includes a disc-shaped basic body, in which at least one spring bridge is inserted. The basic body has at least one dynamic throttle point to throttle a fluid flow. The basic body has a resilient configuration in a region of the at least one throttle point. Accordingly, an opening cross section of the at least one throttle point is configured to be set variably depending on a pressure difference.

Abstract: A device for throttling a fluid flow includes a basic body which has at least one throttle point with a predefinable opening cross section. The basic body has a resilient configuration at least in a region of the at least one throttle point. Accordingly, the opening cross section of the at least one throttle point is configured to be set in a variable manner as a function of a pressure difference.

Abstract: An electric motor includes an armature shaft which is mounted in at least one floating bearing. The floating bearing comprises a bearing inner ring, which is positioned on the armature shaft, a bearing outer ring, which is received in a bearing seat, and a fluid pump for a vehicle fluid system having the electric motor. Lubricant disposed between the armature shaft and the bearing inner ring forms a hydrodynamic lubricant film and generates a constant relative movement between the armature shaft and the bearing inner ring.

Abstract: In a hydraulic fluid pump, in particular for a vehicle brake system, having a housing and a piston that is mounted in an axially movable manner in the housing in a piston chamber. A drive moves the piston and a sealing element seals off the piston chamber in the direction of the drive. The sealing element is designed as a diaphragm that extends through the piston chamber transversely with respect to the movement direction of the piston.

Abstract: A method and a device, respectively, for detecting the amount of wear on the carbon brush drive system of an electrically commutated d.c. motor which is used, for example, in the form of a pump motor in a motor vehicle. The d.c. motor is driven by at least two carbon brushes and includes means for detecting the generative follow-up voltage. The amount of wear on at least one carbon brush is derived from the time behavior of the generative motor voltage and displayed to the driver.
