摘要： A hydrodynamic-mechanical vehicle drive wherein an engine drives the primary portion of an input clutch whose secondary portion can receive torque with varying degrees of slip and rotates the pump of a counter-rotating hydrodynamic torque converter, either directly or through the medium of a differential. The turbine of the converter is adjacent to the inlet side of the pump and drives the input shaft of a reversing gearing which utilizes a friction clutch to drive the take-off shaft forwardly and a friction brake to drive the take-off shaft in reverse. The turbine and the pump rotate in the same direction during hydrodynamic braking and the pump is then rotated at a speed which depends on the degree of slip of primary portion of the input clutch relative to the secondary portion. The clutch or the brake of the reversing gearing operates without slip during hydrodynamic braking, and the converter has a guide blade ring which is disposed between the pump and the turbine, as considered in the direction of fluid flow in the converter chamber from the pump toward the turbine. The ring changes the direction in which the fluid circulates under the action of the pump. The control system of the drive includes a control valve or an analogous component which changes over the reversing gearing in response to a braking command, and means for automatically increasing the slip of the input clutch when the control valve changes over the reversing gearing.

摘要： The compressor includes a housing defining a pressure space including chambers and passages connected thereto for conveying sealing and lubrication liquid to and from an impeller shaft rotatably mounted in the housing. The impeller shaft is stepped and mounted for limited radial movement, and includes an elastically bendable torsion shaft portion having a diameter which is a minimum with respect to the torsional stresses imposed thereon. A relieving piston is carried by the torsion shaft portion and the impeller shaft further includes a main compressor shaft portion carrying at least one impeller. A torsion shaft sealing surrounds the torsion shaft portion and serves as the main sealing forming a shield between the pressure within the pressure space and atmospheric pressure. A sleeve surrounds the relieving piston and is formed with axially spaced grooves in its surface facing the relieving piston, and annular discs are mounted on the relieving piston and cooperate with the grooves to compensate the axial thrust. A chamber is defined, on the one hand, by the torsion shaft portion and the torsion shaft sealing end, on the other hand, by the relieving piston, the sleeve and the housing, and a supply conduit is connected to this chamber to supply sealing and lubricating liquid thereto serving to absorb the internal pressure within the housing.
