HYDRAULIC DRIVE AND BRAKING SYSTEM

摘要

A hydraulic drive and braking system for vehicles has at least one hydraulic machine (primary machine 71), preferably a pump, and at least another hydraulic machine (secondary machine 2), preferably an engine. Both hydraulic machines are linked to each other by corresponding hydraulic medium ducts. Besides the primary machine, a second hydraulic machine (accelerating machine 71') is non-rotatively coupled to the driving source (69). The accelerating machine (71') is rotatively coupled to the driving source (69). The accelerating machine (71') is in communication over I/O valves (14, 15) with an accumulator (4) and it (71') has an adjustable stroke.
