摘要： A composite accumulator includes a base having a closed end and an open end, the base having an inner surface that defines a cavity and having a fluid port in communication with the cavity for communicating a hydraulic fluid in and out of the cavity. A cover is disposed over the open end of the base and is secured to the base by a fastener. A piston is disposed within the base and the cover. The piston is sealed to the inner surface of the cover and is translatable along an axis. A biasing member is disposed within the base and the cover and located axially between the piston and the cover. The base and the cover are plastic.

摘要： A dual clutch transmission having improved packaging and reduced spin losses provides a five, six or seven forward speeds and reverse. An input shaft includes two or three gears which are in constant mesh with and directly drive associated gears freely disposed on a pair of parallel quills. Synchronizer clutches associated with these driven gears selectively synchronize and connect the gears to the quills which are, in turn, connected to countershafts residing within the quills. Additional gears which are in constant mesh with a pair of ring (output) gears are synchronized and connected to the countershafts by additional synchronizer clutches. Activation of two synchronizer clutches and one input clutch provides a selected gear ratio and transfers torque from the input shaft to the output ring gears.
