Transmission e-Fluids

Improving the efficiency and extending the life of the drivetrain system.

Transmission e-Fluids

ADVANCED TRANSMISSION E-FLUIDS FOR DRY and WEt e-motors

The demands on e-transmissions are more severe than conventional transmissions, with maximum torque delivered at low speeds and the increasing integration of electric motors into the transmission. Castrol are developing transmission e-Fluids that protect the gears and maintain required di-electrical properties and component compatibility to allow electronics to function correctly over their lifetime.

THE CHALLENGE

Future EV motor-transmissions can be enhanced by adding a shifting device to reach higher speeds, operate with synchronizer systems at high speeds and loads and to enable the eMotor to drive in the most efficient range.

 

OUR TECHNOLOGY

Castrol Wet Plus Transmission e-Fluid’s specially-developed technology, with its optimised friction levels for synchronizer systems and clutches, allows efficient shifting under high loads and speeds and to operate the eMotor in the most efficient range.

 

THE RESULT

Castrol Wet Plus transmission e-fluids help extend the life of the drivetrain system.

Castrol Wet Plus Transmission e-Fluid provides enhanced friction control allowing efficient and stable shifting under all driving conditions in multi speed gearboxes.

Wet Transmission e-fluids

THE CHALLENGE

EV motors can generate extremely high torque at low speeds.  The transmission element has to deal with more than double input speeds from the motor and the motor unit operates immersed in the transmission fluid. 

 

OUR TECHNOLOGY

Castrol Wet Transmission e-Fluid’s low viscosity formulation is specifically developed to deliver low electrical conductivity, enhanced system protection and helps the e-motor run cooler enabling it to operate at high efficiency.

 

THE RESULT

Castrol Wet Transmission e-fluids help extend the life of the drivetrain system.

Castrol Wet Transmission e-Fluid provides enhanced transmission cooling for improved e-motor performance and has reduced electrical conductivity compared to conventional fluids, protecting the motor against arcing.

DRY TRANSMISSION E-FLUID

Dry Transmission e-fluids

THE CHALLENGE

EV motors can generate extremely high torque at low speeds. The EV transmission must deal with this and can face more than double input speeds from the electric motor, putting the lubricant under immense stress.

 

OUR TECHNOLOGY

Castrol Dry Transmission e-Fluid helps overcome the challenges the drivetrain system faces by providing enhanced protection, reduce viscosity loss and fast release of entrained air.

 

THE RESULT

Castrol Dry Transmission e-fluids help extend the life of the drivetrain system.

Castrol Dry Transmission e-Fluid provides enhanced transmission protection, helping extend the life of the drivetrain system and increase the vehicle range per battery charge.
