  • Patent number: 8944954
    Abstract: The gearing has an input element (8) which is connected in terms of drive to an output element (9) via gearing elements. One of the gearing elements is a regulating element (12) with which the rotational speed of the input element (8) can be changed for passing on to the output element (9). The rotational speed of the output element (9) is increased when the rotational speed of the regulating element (12) decreases. The torque present at the input element (8) is conducted on via the regulating element (12) to the output element (9) such that the input torque is present at the latter.

  • Patent number: 7198013
    Abstract: A device and method for the relative adjustment of the angle of rotation of a camshaft with respect to the crankshaft of an internal combustion engine that utilizes a hydraulically activated actuating element, through the adjustment of which the phase position of the camshaft can be directly or indirectly changed. The actuating element is bordered by two pressure chambers, which can be loaded with or relieved of hydraulic fluid via control lines. A control valve is provided, which, depending upon an operating state of the internal combustion engine, forces a flow of oil that is forced from an oil reservoir by an oil pump via a first control line to a first pressure chamber, while oil from a second pressure chamber is returned to the oil reservoir via a second control line, and vice versa. At least one controlled bypass is arranged between the two pressure chambers. In this manner, the speed of adjustment of the camshaft adjuster can be advantageously increased.

  • Patent number: 6871621
    Abstract: A camshaft adjuster for motor vehicles has a stator and a rotor rotatable relative thereto between which pressure chambers are provided. Pressure medium is supplied in a controlled way via a valve to the pressure chambers in order to rotate the rotor relative to the stator. Mounting of the valve in the internal combustion engine of the motor vehicle is often difficult when mounting conditions are tight, sometimes even impossible. In order for the camshaft adjuster to be usable even in tight spatial conditions, the valve is arranged on the side facing away from the camshaft connection. The valve can therefore be arranged stationarily axially outside of the engine of the motor vehicle. The camshaft adjuster requires thus only little mounting space.

  • Patent number: 6742486
    Abstract: A system for relative angle-of-rotation adjustment of a camshaft of an internal-combustion engine. An adjusting unit has an interior part connected with the camshaft, and a cell wheel with several cells distributed along the circumference. Interior part webs divide the cells into two pressure spaces. Hydraulic pressure admitted or relieved from the pressure spaces causes camshaft rotation between two end positions. A movable locking element in the cell wheel or the interior part opens up a hydraulic line to a pressure space when in an unlocked position. When in a locked position, bores in the interior part are closed off. The locking element can move into first and second unlocking positions, whereby the various bores are opened at desired intervals as the locking element moves. As a result, the useful life and the functionality of the locking device is improved.

  • Patent number: 6742484
    Abstract: At least one locking device between an interior part and cellular wheel, which is equipped with a movable locking element that acts together with at least one counter-element in a respectively other component of the two components cellular wheel or interior part, causes the interior part to be able to be locked relative to the cellular wheel in at least one final position. The locking and/or unlocking process of the locking element occurs through at least one oil duct that leads to the locking element. Between two pressure chambers in or on the cellular wheel an opening connected with the oil duct is arranged, whose passage to the two pressure chambers is controlled in dependence on the adjusting position of the interior part. This way, the cam shaft adjusting unit can be locked safely.
