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).

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.

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.

Vehicle electrification

The growing presence of electronic components in vehicles promotes better control, more safety and precision in the driving. In Cojali, we manufacture electronic components to optimise the performance of all systems, help the predictive maintenance and the reduction of possible failures.

Electromagnetic compatibility

The electronic components generate magnetic fields during their operation.<br>These fields can have an influence in the electronics of near components, therefore, a correct design is necessary. In Cojali all our components are designed under the ECE R10 regulation that stablishes the criteria that each electronic component must meet so that it can be installed in total safety.

Control of the whole lifecycle of the product

One of the most advanced assembly technologies of electronic components are the SMD assembly lines. In Cojali, we have this type of processes to ensure the comprehensive control of the production of electronic components.

Fuel consumption reduction

In order to monitor and reduce the fuel consumption, in Cojali we develop and manufacture sensors capable of knowing at all times the vehicle state, transmitting this information to all control units and optimising the operation of all systems.

Compliance with the emission standards

The demandable Euro 6 emission standards can be only met with high-technology sensors.

Therefore, in Cojali we manufacture NOx sensors and exhaust gas temperature sensors with a thoughtful design and high-quality materials, which guarantees their effectivity and their proper operation.

Driving comfort

The truck cabin is the drivers’ work “office”, therefore, it is essential that they feel comfortable during their working hours.

Some components of the climate control or driving assistance panels help with this comfort.

In Cojali we are committed to the repair and extension of the useful life of components with electronic control through our Cojali Reman range. A process that contributes to the environmental conservation and cost reduction for our customers. Our catalogue of remanufactured products includes brake callipers, valves, brake and suspension systems and ECUs, thereby covering a big part of the vehicle components subject to failure.

New possibilities for the workshop.

At Cojali, we provide the workshops with our repair service. We perform repairs through a complex and detailed process in which all components susceptible to wear are tested and replaced by new ones. Then, we check that the component is ready for assembly, while preserving the same specifications as the new original product.

Time reduction.

In Cojali we guarantee the delivery of the repaired part within 24-28 hours from its the arrival to our facilities and failure detection.

Exchange sale.

Cojali offers an exchange service of repaired parts. With this service, we can reduce even more the time, since it is not necessary that you send us the part to be repaired previously and within 24 hours you will receive the requested part.

Cost reduction.

The repair can be a 50% more economic than the acquisition of a new component, that is not really necessary, meeting all the original specifications of the product.

Environmental conservation.

Thanks to the remanufacture system, we can restore components at the end of their useful life so that they recover all their functionalities. Thereby contributing to the sustainability, avoiding environmental impact derived from the manufacture and implementation of a new component in the market.

Cojali standard. Our cooling systems adaptable to the main brands of truck, bus, light vehicle, passenger car, agricultural machinery and construction machinery are manufactured under the most demanding quality standards, as the ISO 16750, and they certify a long useful life, as well as the optimisation of the vehicle performance.

Together with our R+D+I team, made up of more than 100 industrial engineers, we insist on developing products that contribute to the optimal and sustainable operation of the components patenting our technology.

Know our cooling system in depth. Choose Cojali brand.

Efficiency and environmental care

The system of viscous clutches with fan is specially designed to be as energy efficient as possible in the vehicle cooling system. In Cojali we develop this system taking into account the cooling needs in any work condition, optimising the air flow generated by the fan. In this way, the fan speed is reduced in circumstances where the engine temperature is low, reducing the fuel consumption and noise level and thereby minimising the environmental impact.

High reliability and long useful life

In Cojali we guarantee high reliability and long life in all our products for cooling systems. The viscous clutches manufactured under the Cojali brand are devices that have no components in contact, therefore its wearing is reduced to the maximum. This is one of the main reasons why the viscous clutches present a huge advantage regarding other devices with the same functionality, as for example friction clutches of viscous clutches of the competence. Furthermore, our Quality Department implements a thorough control of the production process, showing special interest in ensuring that the product is finished in optimal conditions for its function.

Flexibility and product variety

We manufacture a wide range of clutches and fans for commercial vehicles, as trucks and buses, agricultural vehicles, construction machinery and light vehicles. We currently cover the 95% of the European market and are growing in the American and Asian market. Within the product range, there are clutches with different activation types and formats, and plastic fans with different characteristics. Furthermore, in Cojali we offer a lot of flexibility in the production of small amounts of product, thanks to the innovative design of our production line, that allows the manufacture of any clutch or fan reference available in the catalogue, without the need of big changes, saving in production costs.

Product customisation ability

Our Engineering Department develops each clutch and fan reference taking into account the specifications of each application. In Cojali we optimise the design to achieve a final product with the best offer in quality and price. Furthermore, we adapt to any product requirement for new application requests, offering specialised technical support if needed.

Quality control of finished product

The 100% of the components for cooling systems manufactured in Cojali undergo a thorough quality process to guarantee that the product specifications are met before its installation in the vehicle. In the case of the clutches, they undergo a specific test for each reference known as “end of line test”, that consists in simulating in a test bench the behaviour of the clutch in different operation phases. In the case of the fans, the 100% undergoes a balance test, to guarantee the stability of the fan-clutch system.

In Cojali we give priority to the driving safety and the resource optimisation. Therefore, complying with the most demanding regulations of the sector, as UNECE R13, SAE J1469 and DIN 74060-10, we develop and manufacture the best brake and suspension systems compatible with the main brands of truck, bus and trailer.

With a R+D+I Department made up of more than 100 industrial engineers, from Cojali we offer a catalogue in constant evolution and completely adapted to the technological advances of the automotive industry.

Know our pneumatic brake systems in depth. Choose Cojali brand.

Fuel saving thanks to the compressed air management

The power consumption of the compressor can oscillate between the 1-8% of the total power generated by the engine.

In Cojali we know that reducing this variable will mean a strategic advantage, not only in the sense of power, but also of increasing the useful life of all components.

A good management of the compressed air makes possible to optimise the operation of each of the valves that are part of the pneumatic system.

Toward electronic control in braking systems

For some years, the whole industry has evolved toward the electronic control and the VI braking system is no exception.

The electronic control has as main advantage the response speed of the system. In Cojali, we give special importance to this variable being aware of its relevance for the dynamic control of the vehicle (braking distance reduction, stability control…).

Compatible braking between truck and trailer

Some commercial vehicles combine several vehicles at a time and it is important that both of them perform the braking accordingly. The trailer control valves of Cojali transfer the braking request ensuring always the stability and coordination between them.

Braking safety

In a brake system, it is essential that the drivers feel safe every time they press the brake pedal.

Our foot brake valves afford a soft and gradual braking so that the driver feels the control of the vehicle at all times.

The most modern formats of this type of valve include an integrated electronic sensor to improve this comfort.

Transformation of pneumatic energy into mechanic energy

In the brake system, it is necessary to apply mechanic force on the brake drum or disc for the braking process.

The brake actuators or chambers of Cojali are in charge of transforming the pneumatic energy into braking mechanic energy.These products include IBV technology to avoid exposition to external humidity.

Long useful life

All valves of the vehicle pneumatic systems are exposed to adverse working conditions: high operation pressure, corrosive environment, humidity, etc. The valves of Cojali braking systems are manufactured with the best materials to guarantee the long useful life of all components.
