Gear Lubrication/Cooling TRIZ Cases
- Integrated ATF Reservoir With PTC Heating for Faster Cold Starts
A PTC-heated ATF reservoir speeds cold-start fluid warming, improves viscosity control, and saves engine-room space with an integrated cooler.
- Vehicle Drive Oil Layout for Rotor Clearance and Lubrication
An oil receiving portion, supply passage, and raised discharge port keep oil below the rotor while sustaining transmission lubrication during vehicle tilt.
- Coaxial Axle Oil Baffle Mounting to Reduce Churning Losses
Using existing axle housing holes and fasteners, a coaxial modular baffle cuts fluid splashing and churning without extra machining.
- Integrated Oil Routing for Electric Drive Cooling and Lubrication
Active oil pumping and return passages direct lubrication and cooling to motor and reducer parts, improving heat removal under high load.
- Oil Accumulation Cover Structure for Stable Bearing And Gear Lubrication
An enlarged oil accumulation section and raised communication passage keep oil at bearing and gear low points to reduce wear and stabilize lubrication.
- EV Transmission Pre-Heating Using Coolant Heat Exchange
Cold-start EV losses are reduced by routing heat-source energy through a transmission heat exchanger to warm lubricant before driving.
- PTO Oil-Guiding Housing for Gear Cooling and Lubrication
Rotating gears drive oil toward a guided outlet, improving PTO cooling, lubrication, and oil removal in electric vehicle powertrains.
