Electric Vehicles Robotics Industrial applications Multi-Cone-Clutches Multi-Speed Transmissions
A Strategic & Technical Snapshot
𧩠Why Cone Clutches Make Sense for EVsCone clutches solve the two big problems that make traditional dogâclutch or synchro-based multiâspeed EV transmissions unattractive:
â High torque at zero RPM EVs produce instant torque, which destroys dog clutches and makes synchronisation difficult. A cone clutch loves torque because the wedging action increases holding force.
â Smooth, slipâcontrolled engagement With motorâassisted synchronisation, a cone clutch can engage seamlessly with minimal heat and wear.
â Large torque capacity in a compact package A cone clutchâs surface area and wedging angle give it far higher torque density than flat clutch packs.

đ§ Architecture Advantages (EVâOptimised)
- 1) MotorâAssisted Synchronisation
- The EV motor itself becomes the synchroniser.
- This eliminates:
- synchro rings
- blocker mechanisms
- shift shock
- high wear
- 2) Stacked Cone Torque Multiplication
- Stacked cones multiply torque capacity without increasing diameter.
- This is the core of EVCCâs advantage:
- High torque, low axial force, compact packaging.
- 3) 2âSpeed or 3âSpeed Layouts
- 2âspeed: ideal for passenger EVs
- 3âspeed: ideal for performance, towing, commercial, or motorsport EVs
- 4) Low Heat, Low Losses
- Because the clutch only slips briefly during synchronisation, thermal load is tiny compared to wet clutch packs.
- 5) Competitor list:
- Legacy EV Transmission Approaches:
- 2-speed dog clutches Porsche Taycan)
- Wet multi-plate clutches (ZF, Magna)
- Planetary gearsets (Toyota, GM hybrids)
- đ Commercial Advantages
- â Higher efficiency
- Improved lowâspeed torque and highâspeed efficiency.
- â Smaller motor
- A multiâspeed EV can downsize the motor while maintaining performance.
- â Better towing, hill climbing, and sustained power
- A fixedâratio EV overheats under load; a multiâspeed EV doesnât.
- â Patentable differentiation
- Coneâclutch EV transmissions are not widely explored by OEMs, giving strong IP defensibility â especially with multiâcone, EVânative actuation.
- đ Competitive Landscape
- Most competitors use:
- 2âspeed dog clutches (Porsche Taycan)
- Wet multiâplate clutches (ZF, Magna)
- Planetary gearsets (Toyota, GM hybrids)
- None of these match the torque density, smoothness, or simplicity of a multiâcone EV clutch.
