Gearboxes TRIZ Cases

A partitioned transmission case uses ring-gear oil transfer and gravity return to balance differential lubrication and stirring resistance across speeds.

A pre-assembled slotted hollow-shaft coupling uses friction clamping to avoid jamming while enabling secure, torsionally rigid torque transfer.

A separate central gearbox lets open-roof systems reuse ATS motor controls while vibration dampers cut noise and cabin vibration.

A constant-section cylindrical motor case simplifies assembly, improves alignment, and cuts noise, vibration, and manufacturing cost.

A rotary pop-up screen adjusts display exposure to keep key driving information visible while limiting view obstruction during infotainment use.

A coaxial double-planetary layout cuts gear idling and power loss, raising ground clearance while reducing noise, leakage, and maintenance.

An eccentric transmission-differential layout improves lubricant circulation, limits sedimentation, and supports flexible torque paths in compact vehicle powertrains.

A nested rotor and gear shaft layout uses three bearings, wave spring preload, and balancing to reduce misalignment, noise, weight, and assembly effort.

A brake disk placed between parallel drive and driven shafts saves axle space and cuts vibration and noise by braking after speed reduction.

A shared gearbox lets heat-engine and electric-motor power split by flight phase, improving cruise fuel use while avoiding oversized engines.

A shared oil flow path combines gear lubrication and cooling through the pump and cooler, cutting drive unit size and circuit complexity.

A two-step PTO adapter attachment creates torque-wrench clearance and avoids supporting the full PTO, helping prevent leaks and fastening failures.

A banjo-style axle housing with bolted side access, stiffening plates, and sealing cuts weight while preserving strength and serviceability.

An axial oil passage links bearing holding portions to feed lubricant into deep reduction-gear bearings for stable lubrication and cooling.

A motor-driven screw bar tilts the vehicle AVN monitor toward the passenger seat, improving viewing access without losing driver usability.

A parallel motor layout and carrier-integrated park lock make the electric drive axle more compact while protecting strength and service life.

A bolt through the intermediate shaft bore stiffens the gearbox cover near the shaft, reducing deflection, mesh misalignment, and bearing wear.

A threaded stopper assembly cuts fit gaps in adjustable antenna drives, improving initial phase calibration accuracy with fewer parts.

A three-part vehicle drive case supports parallel drive sources while cutting sealing interfaces, reducing sealing parts and manufacturing cost.

An inertia body on elastic suspension helps a vehicle anti-vibration mount filter vibrations above 600 Hz without added size or durability loss.

An extending member shifts the ring gear connection in the thrust direction to cut radial vibration transfer to the case and reduce noise.

A portal trailing arm with meshed gears transfers torque while maintaining track width and suspension geometry on rough off-road terrain.

Separating the strainer chamber from the gear chamber keeps oil at the pump inlet, reducing air suction and improving circulation.

A cycloidal reducer with permanent magnet synchronous motors improves torque precision, compactness, and resistance to sudden jolts.

A replaceable orientation sheet with an oil groove cuts friction noise while improving casing tightness and mounting strength.

Nested seal loops and a vent space keep hydraulic fluid, coolant, and air separated while enabling sensor-based leak detection.

External power preheats hydraulic fluid during charging, cutting battery drain at cold start while keeping work vehicle hydraulics ready.

A shaft-integrated oil pump uses rotation to cool the gearbox and electric machine efficiently while preventing fluid intrusion into the air gap.

By placing the band brake actuator beside the outer and side walls, this case shows a compact stepped transmission layout without losing gear switching.

Dynamic oil pump speed control adjusts lubricant level and pump power to cut churning loss while maintaining motor and reducer cooling.

A gearbox-side bolt layout enables vertical vehicle axle drive assembly, avoids upending, and improves tool access in tight housing spaces.

A coaxial dual-gear-ring layout places the wheel between drive rings to cut installation space and enable full 360° steering.

A beaded or locally reinforced cover limits axial deformation under gear stress, improving seat lifter gear stability and durability.
