Differential Gearings TRIZ Cases

A vehicular differential apparatus uses a single center washer with distinct axial clearances for coupling members and side gears.

Pre-calculating shim thicknesses based on target apex positions minimizes NVH issues at high rotational speeds.

Pre-machined differential housing flanges guide laser weld seams and absorb fumes, reducing pores and distortion in ring gear assemblies.

Interlocking thrust members and conical disc-shaped springs bias side gears to reduce radial movement, noise, and overrunning in limited slip differentials.

Sawtooth profile on ring gear inner surface establishes precise alignment with differential housing, eliminating installation errors and reducing pinion wear.

A differential lock actuator uses a reed switch and magnet for contactless position sensing.

A ferrous shield member encloses a magnetic field sensor and sensing magnet to isolate detection components from electromagnetic coil fields.

Segmented ring gear design isolates welding heat from critical gear teeth, suppressing thermal distortion and maintaining structural durability.

Segmented fixtures clamp differential case portions independently, enabling angular laser welds that reduce stress concentration and improve joint strength.

Continuous temperature modeling reduces drive torque when limits are exceeded, protecting differentials from heat damage.

Removal of snap rings from the differential mechanism prevents holdout ring displacement during speed variations, eliminating clutch damage risks.

Cam assembly moves clutch members axially to disengage from the central driver, reducing noise and vibration during speed differentials.

Segmented pinion housing projections distribute torque loads to resolve gear strength limitations in helical face gear differentials.

An externally mounted plenum pumps hydraulic fluid to actuate a differential piston, eliminating the need to modify the transaxle housing structure.

A compact bevel differential gear mechanism uses a densely packed pinion array to transfer torque between side bevel gears.

Controller commands differential lock activation using articulation and steering angle sensors to maintain traction during straight travel.
