Differential Gearings TRIZ Cases
- Differential Ring Gear Welding Distortion Control
Segmented simultaneous welding reduces thermal strain and distortion in flange-to-ring gear joints while preventing spatter ingress into the differential case.
- Radial Shaft Pin Locking Differential Assembly
Radially extending shaft pins replace axial bolts to reduce weight and assembly complexity in mechanical locking differentials.
- Solenoid Valve Damper Chamber Oil Filling for 4WD
A working-oil filling member positions above the reservoir surface to reliably fill a damper chamber within an electromagnetic solenoid valve.
- Helical Gear Differential Pre-load Mechanism
A spring-loaded thrust block biases helical gear differential side gears to reduce component wear.
- Axle Assembly with Annular Band Retainer
Axle assembly uses an annular band and secondary retainer to support the shaft.
- Differential Assembly Link Pinion Mounting
A differential assembly mounts pinion gears directly on links between flange members to reduce component count.
- Electromechanical Dual-Wheel Differential Locking System
An electromechanical actuator moves a locking pin to engage the inner and outer hubs, eliminating manual nut operation that requires exiting the vehicle.
- Torque-Responsive Differential Brake for Directional Stability
A differential brake device couples output sun gears via friction to enhance vehicle directional stability.
- Parallel-axis helical differential with integral brake shoes
Integral case shoes frictionally engage helical pinions to limit differential motion, preventing gear misalignment during high torque loads.
- Power Transfer Unit Disconnect Mechanism for FWD AWD Package Space
A hydraulic servo actuates a clutch within the transaxle to disconnect power transfer between the power source and secondary axles.
