A method and system for estimating the remaining useful life of a filter in a lubrication system is disclosed along with exemplary system components.

A straddle vehicle includes: a prime mover; a hydraulically actuated main clutch; an oil control valve unit; a power unit case accommodating at least the main clutch; an oil pan mounted beneath the power unit case; a clutch-dedicated pump; a primary filter disposed in an oil passage between the oil pan and the clutch-dedicated pump; and a secondary filter disposed in an oil passage between the clutch-dedicated pump and the oil control valve unit. The primary filter and the secondary filter are mounted on a bottom surface of the power unit case and covered from below by the oil pan.

The present disclosure is directed to a filter system for a wind turbine, comprising at least a filter device having a filter housing with a volume portion and a cap portion, both defining a filter volume for receiving the oil filter. The filter housing is equipped with an inlet port, an outlet port and a pressure port. The filter system further comprises a pressurizing device having an interface port, and supply means for providing pressurized gas via the interface port, preferably into the filter housing of the filter device. The pressurizing device is configured for being connectable to the pressure port, preferably via a compensation duct. Furthermore, a method is disclosed, wherein the pressurizing device is connected to the filter housing, lubricant is discharged by applying pressurized gas into the filter volume, the cap portion is removed and an oil filter is subsequently replaced.

An oil strainer is arranged between an oil pan configured to close a lower opening of a transmission case and a control valve body which is installed in the lower opening. The control valve body has a discharge hole of oil in a portion opposing the oil strainer. The oil strainer has an oil suction port in a portion opposing the oil pan, and has a rib projecting on the control valve body side on a surface of a portion opposing the control valve body. When seen from the oil pan side, the oil suction port and the discharge hole are provided so that positions are not matched from each other. When seen from the oil pan side, the rib is provided to cross a straight line passing through the oil suction port and the discharge hole in a region between the oil suction port and the discharge hole.

Provided are a lubricating system and a pumping unit including the lubricating system. In addition to the lubricating system, the pumping unit further includes a rack, a transmission wheel located in the rack, and a transmission conveying device cooperated with the transmission wheel. The lubricating system includes an oil pool and a roller lubrication device. A bottom of the transmission wheel is impregnated in the oil pool. The roller lubrication device is in rolling contact with the transmission conveying device. An oil return device is disposed above the oil pool and configured to collect splashing oil driven by the transmission conveying device. After the splashing oil is cleaned twice, the splashing oil flows back into the oil pool.

A liquid filter has inflow and outflow faces connected by a throughflow path. A one-piece filter body of a folded filter medium bellows is provided. Each fold has first and second fold sheets joined at a fold edge and two fold end faces. The filter body is installed into a pre-defined installation space of a vehicle, the installation space defined and delimited by a base free-form surface, a cover free-form surface, and a side free-form surface. The fold edge heights of the folds are adapted to a contour of cover free-form surface; base free-form surface; or cover and base free-form surfaces. First folds with first fold edge height and second folds with second fold edge height that differ from each other are provided. Third folds have fold end faces adapted to a contour of the side free-form surface facing these fold end faces. An envelope around all fold end faces and rim folds deviates from a rectangle.

A removable oil filter system includes an oil filter mount, an oil filter element removably connected to the oil filter mount, an impending-bypass indicator connected to the oil filter mount and in fluid communication with an oil in the oil filter system, and a full-bypass indicator in fluid communication with the oil filter mount. The impending-bypass indicator is capable of reporting an impending-bypass condition of the oil filter system. The full-bypass indicator is capable of reporting a full-bypass condition of the oil filter system.

A hybrid drive module, comprising an electric motor (110) and a power electronics module (300) operatively connected to the electric motor (110) whereby the power electronics module is integral to the electric motor (110).

The invention relates to a pressure oil filter system for a hydraulic transmission, in particular for a motor vehicle transmission, comprising at least one oil pump which can be actuated as required and which has a pressure side and a suction side, a pressure line to a consumer and at least a first oil filter which is arranged at the pressure side of the oil pump in the pressure line, wherein means for damping pressure surges during intermittent operation of the oil pump are provided in the pressure line upstream of the first oil filter in the flow direction of the oil.

A parking lock for a transmission of an electric or hybrid vehicle is disclosed. The parking lock includes a lock device including an actuatable actuating element and a setting element adjustable between a deployed position and a retracted position. The locking device is configured such that, in response to repeated actuation of the actuating element, the setting element is, via a coupling mechanism, adjusted alternately between the retracted position and the deployed position. A camshaft is provided with a cam arranged on the camshaft that is connected in terms of drive to the lock device. A ratchet wheel is provided with a pawl that is adjustable between an engagement position, where the pawl blocks a rotation of the ratchet wheel, and a release position, where the blocking of the ratchet wheel is released. The setting element adjusts the pawl between the engagement position and the release position.
