TRANSMISSION AND POWER SYSTEMS

We offer a wide catalogue of components for the transmission and power systems of the main brands of truck and bus. Our clutch servos use the most modern techniques in hydraulic or pneumatic transmission and they are designed carefully to get answers in a matter of seconds.

The transmission systems are having a fast transition to components that integrate electricity and electronics to these technologies. Thanks to the R+D+I team of Cojali and our vast experience in electronic systems, our product catalogue is in constant evolution to offer the market these new hybrid developments.

Gear shift comfort

Gear shift comfort

The gearbox is in charge of adjusting the transmission relation so that the vehicle optimises the power with a balance between revolutions and torque supplied.

The Cojali components have an optimal response speed so that this adjustment is performed within fractions of a second.

Furthermore, the automatic gearboxes include electronic elements in all peripheral components to achieve this speed in the gear shift.

Pushing force amplification

The clutches need a high activation force for the engagement/disengagement.

Our clutch servos allow an amplification of the applied force by the clutch pedal thanks to the help of the pneumatics system of the vehicle.

This component can be hydro-pneumatic (conventional gearbox) or electro-pneumatic (automatic gearbox).

Pushing force amplification
Sensibility in clutch pedal

Sensibility in clutch pedal

The manual gearboxes incorporate as main components the master cylinder and the clutch servo.

Both components are in charge of transforming the force that the driver applies on the pedal into pushing force on the clutch.

In Cojali, we achieve a good adjustment and quality for these components to ensure a correct sensibility on the clutch pedal.

Importance of the hydraulic fluid

The hydraulic fluid type can vary depending on the application and characteristics of the clutch servo. The most used ones are the brake fluid (DOT4) and the mineral oil (Pentosin). All internal parts that are part of these components are specifically chosen to work with a certain fluid type and, therefore, it is especially important to take this variable into account when performing the vehicle maintenance.

Importance of the hydraulic fluid
Durability and resistance

Durability and resistance

The transmission system undergoes a high number of activations and high mechanical requirements during its operation.

In Cojali, all components undergo the most demandable tests of useful life and protection against corrosion.
