The transmission system is the beating heart that converts raw engine power into wheel motion, enabling vehicles like cars, trucks, and industrial machinery to perform with efficiency and control. This intricate network of components works in unison to transfer power, adjust speed, and ensure precision, whether on a straight highway or a challenging curve. At Leax do Brasil, we recognize that every part of this system matters, which is why we leverage cutting-edge technology and precision engineering to deliver solutions that blend performance, durability, and innovation.

So, how does the transmission system actually work? It begins with the clutch, a key feature in manual vehicles, acting as a switch between the engine and the transmission. When the driver presses the pedal, it temporarily disconnects the engine’s power, allowing smooth gear shifts that adapt the vehicle to varying driving conditions. In automatic models, this role is taken by the torque converter, a fluid-based device that transmits power seamlessly, eliminating manual input and providing a smoother driving experience.

Next comes the gearbox, the brain of the system. It manages the balance between torque and speed, shifting gears to give the vehicle the strength to climb hills or the velocity for highway cruising. Whether it’s a manual gearbox, controlled by the driver’s gear selection, or an automatic one, guided by advanced sensors and electronics, the precision of each gear is critical to prevent wear and maintain efficiency. At Leax, our gearboxes are crafted with minimal tolerances, using CNC machining and heat treatments to enhance component durability.

The propeller shaft then steps in, carrying power from the gearbox to the differential or directly to the wheels, particularly in rear-wheel or all-wheel-drive vehicles. Made up of a sturdy tube, articulated universal joints, and connecting flanges, it endures vibrations and misalignments without sacrificing energy transfer. Leax do Brasil produces propeller shafts with dynamic balancing and high-quality materials, ensuring every rotation is smooth and reliable, even under tough conditions.

Finally, the differential completes the system, smartly distributing power between the wheels. In a turn, for instance, it allows the outer wheel to spin faster than the inner one, maintaining stability and grip. This component demands high-precision parts, like bevel gears and bearings, to function flawlessly. At Leax, every differential is built to exacting standards, embodying our dedication to excellence.

The value of high-precision parts extends beyond basic operation: they minimize wear, extend vehicle lifespan, and optimize fuel efficiency. A poorly designed transmission system or low-quality components can lead to mechanical failures, unwanted noise, or unexpected breakdowns. With over a decade in the Brazilian market and the backing of the Sweden-based Leax Group, Leax do Brasil delivers tailored solutions for automakers and the aftermarket alike. In 2025, we continue to innovate, embracing sustainable practices and advanced technologies to provide not just parts, but trust in motion.
