20100071361 | Compensating Reservoir For A Hydraulic Motor Vehicle Brake System - A compensating tank for a hydraulic motor vehicle brake system, having a housing including a housing upper part and a housing lower part and having a device for monitoring the tank filling level of the compensating tank, including a switching unit, which is welded to the housing and has a plug connector, and including a sensor or switching element which can be switched by a transducer at a switching point S at which the switching unit generates a signal for an electronic control unit. The housing has a depression for holding the switching unit, with the switching unit having a base body composed of plastic, which base body is welded to the housing in the depression, and with the depression being provided such that the base body of the switching unit forms a planar surface with the housing. | 03-25-2010 |
20100308850 | METHOD FOR TESTING A CONTAINER WARNING DEVICE OF A COMPENSATION CONTAINER, AND TESTING APPARATUS FOR TESTING A CONTAINER WARNING DEVICE - A method for testing a reservoir warning apparatus of a fluid reservoir for a hydraulic motor vehicle brake system, with the reservoir warning apparatus comprising a switching unit with at least one reed contact as the switching element. In order to find all possible faults in the reed contact, a dynamic contact resistance and a transient response of the reed contact are measured at the preassembled switching unit. | 12-09-2010 |
20110239758 | METHOD FOR OPTIMIZING THE SWITCHING BEHAVIOUR OF A VESSEL WARNING DEVICE OF AN EQUALIZING VESSEL AND EQUALIZING VESSEL FOR A HYDRAULIC MOTOR VEHICLE BRAKE SYSTEM HAVING A VESSEL WARNING DEVICE WITH OPTIMIZED SWITCHING - A method for optimizing the switching behaviour of a tank warning device of a compensation tank, in particular for a hydraulic motor-vehicle brake system, with a housing and the tank warning device for monitoring the tank filling level of the compensation tank. The tank warning device including a switching unit with a reed contact as a switching element, which can be switched by means of a magnet at a switching point S at which the switching unit generates a signal for an electronic control unit. A compensation tank including a tank warning device which has been optimized in terms of switching by means of a method according to the invention is also disclosed. The reed contact and the magnet are matched to one another in a manner optimized in terms of switching in such a way that the magnet switches at a single switching lobe of the reed contact. | 10-06-2011 |
20110308246 | ASSEMBLY COMPRISING A FLUID RESERVOIR AND A MASTER CYLINDER FOR A MOTOR VEHICLE HYDRAULIC BRAKE SYSTEM - An assembly includes a fluid reservoir and a master cylinder for a motor vehicle hydraulic brake system, the fluid reservoir being fastened to the master cylinder by a releasable connection and including at least one connection fitting, which is received in a corresponding connection aperture of the master cylinder. The fluid reservoir includes one or more components, which under a defined force applied to the fluid reservoir, allow a movement of at least one part of the fluid reservoir in the direction of the master cylinder. | 12-22-2011 |
20120186245 | ASSEMBLY MADE OF A PRESSURE MEDIUM STORAGE TANK AND A MANUALLY ACTUATED MAIN CYLINDER, IN PARTICULAR FOR A HYDRAULIC MOTORCYCLE BRAKE SYSTEM - The invention relates to an assembly including a pressure medium reservoir and a manually actuable master cylinder, in particular for a hydraulic motorcycle brake system, wherein the pressure medium reservoir is connected permanently to the master cylinder by at least one pressure medium connection, wherein the master cylinder has at least one pressure chamber, which can be connected to wheel brakes. According to the invention, provision is made for a protection device to be arranged in the region of the pressure medium connection, the device preventing air from penetrating into the pressure chamber and allowing air to escape in the direction of the pressure medium reservoir. | 07-26-2012 |
20130025274 | CONTAINER, PARTICULARLY FOR HYDRAULIC VEHICLE BRAKE SYSTEMS - The invention relates to a reservoir, in particular for hydraulic motor vehicle brake systems, having one or more pressure medium chambers, a filler neck for filling the reservoir with pressure medium and a pressure medium passage, which is connected to the filler neck and has an opening facing the pressure medium chamber. In order to provide a reservoir which reliably prevents the pressure medium from leaking when the vehicle is in extreme positions and which, at the same time, can be produced in a simple and inexpensive manner, the proposal according to the invention is that the pressure medium passage be provided as a lateral channel which extends in the longitudinal direction along the reservoir, starting from the filler neck, and be formed by walls of an upper part and of a lower part of the reservoir. | 01-31-2013 |
20130036814 | FLUID RESERVOIR FOR A MOTOR VEHICLE HYDRAULIC BRAKE SYSTEM - A motor vehicle hydraulic brake system fluid reservoir for use with an electronic control unit. The hydraulic brake system fluid reservoir has a housing including a reservoir interior space having at least one fluid chamber, and a device for monitoring a reservoir filling level including a switch unit, which with a contact carrier projects into a guide sleeve, which extends into a separate chamber of the reservoir interior space. A sensor element or switch element is arranged on the contact carrier and is operable by a pickup carried on the guide sleeve at a switching point, at which the switch unit generates a signal for the electronic control unit. The separate chamber is connected to the fluid chamber by way of a fluid connection. Valve means are also provided, which serves to control the fluid flow between the separate chamber and the fluid chamber. | 02-14-2013 |
20130152579 | ASSEMBLY MADE OF A COMPENSATING TANK AND A MASTER CYLINDER FOR A HYDRAULIC MOTOR VEHICLE BRAKE SYSTEM - The invention relates to an assembly made of a compensating tank and a master cylinder for a hydraulic motor vehicle brake system, wherein the compensating tank has two fastening attachments, each with an opening, wherein openings align with an opening in the master cylinder, and the compensating tank is fastened by a detachable connection by a fastening pin that extends through the aligned openings. In order to improve the installation and possible dismantling of the fastening pin, and at the same time to maintain an optimized assembly weight, the invention proposes that the fastening pin be made of plastic and interact in a positive- or force-locking manner with at least one of the openings of the fastening attachments. | 06-20-2013 |
