Abstract
A hydraulic transmission circuit is provided having at least two elementary hydraulic motors, each having a secondary enclosure and a main duct for fluid feed and a secondary enclosure and a main duct for fluid discharge. A fluid distributor distributes fluid from the main ducts to the elementary motors via the secondary enclosures. A control system controls the elementary motors. Valves connecting the fluid distributor to the secondary enclosures of the first motor put a secondary enclosure into communication with a main duct independent of an operating mode of any other elementary motor.
Claims18
A hydraulic transmission circuit comprising:
- at least first and second elementary hydraulic motors that are associated for procuring a common drive, each elementary motor having two secondary enclosures, one for feed and one for discharge;
- at least two main ducts respectively for fluid feed and for fluid discharge;
- a fluid distributor for distributing the fluid from said main ducts to said elementary motors via their secondary enclosures;
- and
- a control system for controlling the elementary motors;
- and
- wherein:
- the fluid distributor has valve means connected to the two secondary enclosures of the first elementary motor;
- said valve means being suitable for putting each of the secondary enclosures of the first elementary motor into communication with either one of the two main ducts, independently of the other secondary enclosure, whereby the first elementary motor can be put in a drive operating mode, in an opposing operating mode, or in an inactive operating mode, independently of the operating modes of the other elementary motors.
