Goal
Provide a compact, high-speed transmission that can shift under full load with near-100 % efficiency and significantly higher starting torque.
Problem
Conventional planetary gear transmissions are bulky, cannot shift under load, and lose efficiency during gear changes.
Concept Summary
A planetary gear set housed with an integrated clutch and axial-movable brake disc. The clutch connects two of the three rotatable members, while the brake disc, actuated by a lever, can open the clutch during operation, allowing gear changes under load. The housing is sealed for oil lubrication, enabling a compact, shock-free, high-speed gearbox.
Principles
- Planetary gear mechanics
- Clutch engagement/disengagement
- Axial brake disc actuation
- Lever-based hydraulic control
Scientific Domains
Materials
- Steel
- Oil (lubricant)
- Hydraulic fluid
Mechanisms of Action
- Torque transmission via sun, planet, and annulus gears
- Clutch plates lock/unlock selected gear members
- Brake disc movement disengages clutch during shift
- Lever lever hydraulic cylinder moves brake disc axially
Energy Sources
Applications
- Electric motor drives
- Cranes
- Industrial machinery
- Bicycles
- Vehicle powertrains
Claimed Performance
Near 100 % efficiency, gear change <0.001157 s, up to 7x higher starting torque, up to 40 % smaller electric motor, up to 40 % greater range, 25 % yield increase.
Limitations
- No independent experimental data presented
- Performance claims are not quantified with test results
- Reliance on hydraulic actuation may add complexity
Red Flags
- Lack of published test data or peer-reviewed validation
- Potential overstatement of efficiency and torque gains
