Connecting Rods TRIZ Cases
- Crankshaft Pendulum Absorbers Reduce Vibration Friction
Pendulum absorbers balance rotating crankshaft mass to suppress vibration, reducing friction losses from fewer main bearings.
- Composite Rocker Beam with Radial Clevis Lugs
Machining separates radial clevis lugs in composite rocker beams, resolving the trade-off between high twisting strength and manufacturing complexity.
- Multi-link Engine Geometry Reduces Crank Journal Load
Specific lower link angles reduce crank journal load at bottom dead center, allowing increased piston stroke while maintaining bearing cap strength.
- Hollow Profile Wishbone for Weight and Strength Trade-off
A hollow profile wishbone reduces dead weight while maintaining structural rigidity through optimized geometry.
- Connecting Rod Fracture Start Groove Forming
Mechanical broaching replaces laser heating to eliminate thermal distortion and uneven groove widths while lowering equipment costs.
- Hydraulic Connecting Rod Poppet Valve Control
Segmented poppet valves replace sliding spools in a hydraulic connecting rod, eliminating seal wear and leakage at high engine speeds.
