摘要:
A hydraulic supply system for a motor vehicle includes an internal combustion engine, a pump driven by the internal combustion engine, and a hydraulically operated component that is driven by hydraulic fluid transported by the pump. An electric motor is provided to drive the pump when the internal combustion engine is not running.
摘要:
A hydraulic arrangement by which a plurality of shift rails of a transmission are actuated, including one double acting cylinder per shift rail by which the respective shift rail can be moved back and forth. A first hydraulic valve is connected upstream of the plurality of shift rails and has a first output and a second output, by which a first shift pressure and a second shift pressure for actuating the shift rails can be provided. A second hydraulic valve is connected between the first hydraulic valve and two of the shift rails, and by which it is selectively possible for the first output of the first hydraulic valve to be associated with one of the double acting cylinders of the two shift rails, and the second output of the first hydraulic valve to be associated with the other double acting cylinder of the two shift rails.
摘要:
The invention relates to a hydraulic system for actuating a continuously variable belt-driven conical-pulley transmission having two conical pulleys encircled by an endless torque-transmitting means, each of which comprises two conical disks, one of which is axially movable depending on the pressure in an associated pressing chamber, and having a torque sensor which includes a torque sensing chamber that is connected to a hydraulic energy source and is linked with the pressing chambers.The invention is distinguished by the fact that the pressing chambers are connected via a first hydraulic resistance element to the torque sensing chamber, and via a second hydraulic resistance element to an additional pressure chamber, in which a lower pressure prevails than in the pressing chambers and/or the torque sensing chamber.

摘要:
A conical pulley assembly with integrated torque sensor. A torque-dependent force is transmitted through a transmitting component to a sensing piston whose position determines the pressure in a sensing chamber. The transmitting member is connected to the movable disk, and is formed in such a way that it transmits the torque-dependent force to the sensing piston in a manner that is dependent on the position of an axially movable disk of the conical pulley.
摘要:
An automatic transmission in the form of a belt-driven conical pulley transmission having input side and output side pairs of conical disks. An endless torque-transmitting member extends between the pairs of conical disks for transmitting torque between the input side disks and the output side disks. The strand natural frequency of the endless torque-transmitting member is permanently adjustable to minimize strand vibrations that can cause undesired noise.
摘要:
A swirl disk is composed of at least one metallic material, and is configured as having at least one intake area and at least one outlet orifice, the at least one outlet orifice being introduced in a lower base layer, and having at least two swirl channels emptying into a swirl chamber, the swirl chamber being provided in a central swirl-producing layer. An upper layer is configured as a cover layer, which over its entire cross-sectional surface represents a closed layer without orifice contours. All the layers of the swirl disk are directly built up on top of each other using electroplating metal deposition (multilayer electroplating). The swirl disk is suitable for a use in a fuel injection valve, in particular in a high-pressure injection valve for directly injecting the fuel into a combustion chamber of a mixture-compressing, external-ignition internal combustion engine.
摘要:
A conical disk array for a belt-driven transmission having sets of conical friction disks on the input and output sides that are operatively coupled to each other by an endless torque-transmitting means to transmit torque. At least one friction disk of the conical friction disk sets has a friction surface structure with ground grooves that are not coaxial with each other. A grinding device for grinding the friction surface has its axis of rotation skewed relative to the axis of rotation of the friction disk being ground. A method is for producing a friction surface structure on a friction disk of a conical disk array with a grinding device with which the rotating friction disk serves to form a non-coaxially-oriented friction surface pattern as the friction surface.
摘要:
A belt-driven conical-pulley transmission having a pair of conical disks on a power input side and carried on an input shaft, and a pair of conical disks on an output side of the transmission and carried on an output shaft, each pair of conical disks including an axially fixed disk and an axially movable disk. An endless torque-transmitting means extends around and is in contact with the input side disks and the output side disks for transmitting torque between the pairs of disks. The transmission is optimized to minimize noise emitted by the transmission when it is in operation.
摘要:
A transmission noise attenuation device for a bearing assembly of a belt-driven conical-pulley transmission having a chain that serves as an endless torque-transmitting device. A shaft is rotatably supported in a bearing that includes a bearing outer ring with a cylindrical outer surface, wherein the bearing is supported in a bearing housing. At least one cam ring is positioned between the bearing housing inner surface and the bearing outer ring outer surface. The cam ring is elastically deformable to allow limited radial movement between the bearing housing inner surface and the bearing outer ring outer surface.
