Abstract
A hydromechanical/hydrostatic automotive energy management system comprising two hydraulic units, the system adapted to provide: An efficient, continuously variable optimal transmission ratio, an intermittent optimal engine operation in city traffic and regenerative braking, thereby, the system is able to reduce a car's fuel consumption by as much as one half while improving drivability.
Claims17
An automotive energy management system comprising in combination:
- a housing,
- a first hydraulic unit having a first input/output member, a first reaction member, a first inlet port and a first outlet port,
- a second hydraulic unit having a second input/output member, a second reaction member which is coupled to said housing for obtaining therefrom an external reaction to torque developed in said second hydraulic unit, a second inlet port and a second outlet port,
- clutch means for selectively coupling said first reaction member to said second input/output member, and,
- brake means for selectively anchoring said first reaction member to said housing.
2 more elements
The system of claim 9 wherein said first reaction member carries a swash-plate and a distributor plate between which said first reaction member is sandwiched.
