  • Publication number: 20160254731
    Abstract: An electrical machine is particularly suited as an electric motor of a motor vehicle. The machine has a rotor mounted rotatably by way of a rotor shaft and a position emitter with a rotationally fixed sensor unit and with a sensor emitter fixed relative to the rotor shaft. The emitter is an injection molding with an emitter head receiving a magnet, in particular a magnetic dipole, and with a joint shank. Alternatively, it is provided, together with the magnet on the emitter head side, with an plastic over-molding forming the joint shank. The joint shank is joined to the rotor shaft on the face side of a shaft end by form fit, forming a press fit or an interference fit.

  • Patent number: 9211877
    Abstract: An actuator (1), especially for a motor vehicle parking brake has a telescopic device (2) that actuates a brake cable (6), and a drive unit which is equipped with an electromechanical drive for actuating the telescopic device (2). The actuator (1) further has a displacement sensor unit for detecting the actuating travel of the telescopic device (2) as well as a force sensor unit for detecting the force applied to the brake cable (6) by the drive unit. The displacement sensor unit and the force sensor unit are disposed next to each other in or on the housing (3) of the telescopic device (2) while being separated from the brake cable (6). The assembly has a particularly simple and compact design while reducing the constructive and mounting effort required during the production of the actuator.

  • Publication number: 20150184713
    Abstract: An actuator for a motor vehicle functional unit includes a force transmission unit transmitting an actuating force to an actuating member and being displaced by a measuring travel in a force transmission direction. A force measurement device detects an actual value of the actuating force and includes a spring acting in the force transmission direction, having resilient action counter to which the force transmission unit is displaced and being tensioned by the actuating force over a resilient excursion, a micro switch having smaller switching travel than the measuring travel and being actuated upon displacement of the force transmission unit if the actuating force reaches the actual value, and a stop element for actuating the switch. The switch or element are coupled to or fixed relative to the force transmission unit and the switch and/or element are resiliently supported to compensate for a difference between the switching and measuring travels.

  • Publication number: 20150183413
    Abstract: A gearing unit of a motor vehicle actuator, in particular an electric parking brake, includes a gearing housing in which a driven first shaft and a driving second shaft having fixed rotational axes are located. A first toothed wheel is mounted on the first shaft and a second toothed wheel is mounted on the second shaft. The first toothed wheel and the second toothed wheel engage with one another through a third toothed wheel. The housing for the third toothed wheel has at least two spatially offset bearing points in order to adjust a transmission ratio between the first shaft and the second shaft. An electric parking brake having a gearing unit is also provided.

  • Publication number: 20150152929
    Abstract: A device for generating a force applied to a component includes a force generating element supported on a resilient support device having first and second, or only a second, spring elements in series in a force transmission chain being stressed during force transmission. The first spring element is less stiff than the second. The first spring element is stressed by a first supporting force over a first spring travel. A spring travel exceeding the first spring travel and a force absorption by the first spring element exceeding the first supporting force are prevented by a first mechanical engaging device. The second spring element is formed by a spring module having a second spring stressed by a second mechanical engaging device with a second supporting force permitting the second spring to only be further stressed when exceeding the second supporting force. A travel sensor detects displacement of the force generating element.

  • Publication number: 20140231194
    Abstract: A setting device, particularly a motor vehicle parking brake includes a remotely-operated drive, a hollow shaft, a spindle shaft and an elastic element. The hollow shaft is driven by the remotely-operated drive so that the hollow shaft rotates. The spindle shaft moves relative to the hollow shaft within the hollow shaft due to the rotation of the hollow shaft. The spindle shaft is connected to a brake cable such that the spindle shaft can apply and release the brake as it moves in different directions within the hollow shaft. The elastic element is loaded due to movement of the hollow shaft as the hollow shaft is driven in an attempt to release the brake while the brake cable is blocked.

  • Patent number: 8662263
    Abstract: A setting device, particularly a motor vehicle parking brake, has a telescopic device (2; 3), which can be axially displaced by a setting unit (10) in a housing (1) or the like and which contains a hollow shaft (2) and a spindle shaft (3). This spindle shaft is axially connected to the hollow shaft in a manner that enables it to rotate and advance and actuates a brake cable (4). The setting device also has an axial advancing support between the hollow shaft (2) and the housing (1) via at least one elastic element (5) serving as a force sensor when the brake is pulled or in the event of a blocked brake release. According to one embodiment, a second elastic element (6) is provided for recognizing blocking of the brake cable (4) during an attempt to release the brake and, accordingly, after the release in tension of the first elastic element (5).

  • Publication number: 20080142317
    Abstract: The invention relates to a spindle (1), in particular an electromechanical parking brake of a vehicle, which is embodied as a component of a spindle drive. The aim of the invention is to secure, in a detachable and simple manner, a standard cable pull comprising fittings to a spindle. Said aim is achieved in that a coupling part (7) comprising a receiving section (8) which is used to receive a fitting (9) of the cable pull (6) and a securing section (10) is provided on one free end section (11) of the spindle (1). The securing section (10) of the coupling part (7) are crimped to the free end section (11) of the spindle (1). The invention also relates to a connecting method.

  • Publication number: 20070251774
    Abstract: To provide a simple cable compensation in an actuating device (1), particularly an electromechanically actuated motor vehicle parking brake, a coupling device (20; 40) for canceling and restoring a frictional connection between the actuator (3) and brake cable pull (4)is provided. To this end, the coupling device (20; 40) has a coupling element (21; 41) which, when the brake cable pull (4) is released, can, in order to cancel the frictional connection, be deflected and transferred into a defined final position via a gate (26, 27, 28, 29, 30, 31, 32, 33, 34, 35; 44, 45, 46, 47, 48).
