Bi-Hydrostat for use in hydraulic hybrid drive of motor car, has hydrostats that are arranged one behind another, where one of hydrostats is coupled with main drive shaft over freewheel for transmission of rotation torque

摘要

The bi-Hydrostat (1) has two hydrostats (2, 4) i.e. axial piston machines, comprising drive shafts (7, 8) coupled with a common main drive shaft (15) for transmission of rotational torque. One of hydrostats is rigidly connected to with the main drive shaft to swing in rotation directions (21, 23) for transmission of the rotation torque. Another hydrostat is coupled with the main drive shaft over a freewheel (19) for transmission of the rotation torque, where the hydrostats are arranged one behind another.
