Hybrid Vehicles TRIZ Cases

Maintaining minimum pressure in a working machine return line enables energy recuperation while reducing cavitation risk and hydraulic machine size.

An actuator-driven rocker and strut lock a ring in one rotational direction while allowing freewheeling in the other for hybrid transmissions.

A selected shim compensates clutch sub-assembly and cover tolerances, simplifying torque module assembly while reducing measurements, errors, and cost.

Split ring-gear support shafts shrink bearing size and simplify planetary gear assembly, improving packaging, weight, and installation.

A cam-driven friction clutch replaces hydraulic ratio switching in two-speed EV transmissions, cutting complexity and energy use.

Flywheel recesses clear the torque limiter's engaging portions, preserving torque capacity without radial growth or flywheel interference.

A shaft bore and oil baffle chamber route lube oil to two bearings in tight drive train spaces, reducing separate supply lines and wear.

Pre-charged accumulator flow support helps work machines meet peak hydraulic demand at lower engine speed, reducing fuel use, noise, and parasitic losses.

When return flow and pump demand diverge, a second hydraulic machine supplies make-up flow or recuperates excess energy for efficient, resilient operation.

Nested inner and outer electromagnetic clutches raise hybrid torque transfer while fitting limited transmission space.

Variable pulleys and clutch control let an accessory drive switch power between engine and flywheel, improving energy recovery and reducing clutch slip.

A torsional damper mass doubles as clutch support to cut hybrid module space, drag losses, and engine-start mechanical load.

Time-specific noise caps steer engine, transmission, and movement settings so autonomous machines keep working without breaching worksite sound limits.

Ambient air pressure and temperature are used to predict torque changes, preventing torque gaps and pendulum shifts in self-shifting drivetrains.

A merged backing plate with damping and a piston protrusion improves torque transfer while reducing axial deflection during clutch engagement.

An inward oil drain from the clutch balance chamber lubricates the damper, cutting pump work while lowering resonance, vibration, and noise.

A directional damper mechanism keeps drive-side torque transmission rigid while allowing driven-side torsion to suppress resonance and rattling.

A blended mineral-synthetic transmission oil uses amide and polyol ester additives to keep low viscosity while resisting gear seizure and shudder.

Amide and polyol ester additives let low-viscosity transmission oil maintain gear anti-seizing, resist shudder, and stay usable at high temperature.
