Brembo exhibited at IAA Commercial Vehicle Show in Hanover last week, with a wide range of products dedicated to heavy vehicles
Brembo puts its technological know-how and unrivalled experience to work for the professional, producing extremely reliable braking systems for every category of commercial and industrial vehicle.
These vehicles, whether light (up to 6 tons), medium (from 6 to 16 tons) or heavy (over 16 tons), demand superior braking power as the braking system is subjected to repeated, frequent loads in varying road conditions.
The work demanded of a braking system and the heat that it must dissipate during braking are directly proportional to the mass of the vehicle and the speed it is travelling at when braking starts. The brakes therefore have to work hardest when the vehicle is fully loaded and at maximum operating speed – conditions that are relatively common for a commercial vehicle.
As a result, the braking system is subject to more stress than other vehicles, making it all the more crucial that it be suitable for the application. Brembo responds to these requisites by supplying all the major manufacturers in the segment with original braking systems that set the standards for quality, reliability and durability.
Light commercial vehicles
Light commercial vehicles (up to 6 tons), used for mid-long range transport, require braking systems that offer superior performance and can withstand the stress caused by a combination of intense use, heavy loading and high braking speeds typical of these vehicles. For these vehicles, Brembo produces braking systems boasting excellent performance, outstanding structural strength and simplified maintenance, consisting of brake discs up to 300 mm in diameter featuring exclusive pillar venting technology, and cast iron hydraulic calipers.
The structural strength of these components maintains maximum vehicle efficiency over time, minimizing the frequency and duration of stoppages for maintenance. The superlative engineering of Brembo braking systems also increases the durability of friction materials such as discs and pads.
Medium commercial vehicles
Medium commercial vehicles, weighing generally between 6 and 16 tons, combine the maneuverability necessary for city centers with the performance required for long haul journeys and particularly demanding missions. Brembo’s approach to this market is founded on two precepts: safeguarding the business interests of the client – which equates to a focus on reliability, durability and simplified maintenance – and ensuring the safety and wellbeing of the truck driver.
For medium commercial vehicles, Brembo produces front disc brake systems consisting of oversized hydraulic calipers and pads, and ventilated discs in diameters up to 330 mm.
Heavy commercial vehicles
Heavy commercial vehicles (over 16 tons), used predominantly for nationwide and international transport on highways with very high mileages and average speeds, require braking systems designed with particular regard for the durability of their components. For these vehicles, Brembo designs and manufactures ventilated discs with diameters up to 432 mm that are reliable, resistant and extremely durable thanks to the use of exclusive pillar venting technology.
First and foremost, the calipers in a commercial vehicle must ensure superlative reliability, integrity and safety for years and in all conditions.
Brembo calipers are built to last the entire lifetime of the vehicle and to resist weather corrosion. The design of the seals plays a major part in preventing infiltration and corrosion. Aspects such as reliability, durability and maintenance also play key roles in the design process. For vehicles up to a gross vehicle weight of 6 tons, Brembo designs and manufactures single- and dual-piston front and rear floating hydraulic calipers made from cast iron. For vehicles between 6 and 10 tons, Brembo produces oversized floating hydraulic calipers to satisfy the greater demands for braking power of these vehicles.
There are no peaks in the daily usage of a braking system for commercial vehicles – the system is subjected instead to repetitive thermo-mechanical stress, which the brake disc must withstand effectively.
The discs produced for these vehicles range from 280 mm diameter components weighing approximately 9 Kg for light commercial vehicles, to units up to 432 mm in diameter and weighing over 36 Kg for heavy industrial vehicles. These discs ensure power and durability for braking systems in vehicles that travel frequently fully loaded, but also the braking comfort necessary for passenger transport vehicles.
To achieve this, all the components of the caliper must be engineered to exacting standards and suitably protected from the elements.
Brembo responds fully to the needs of the sector with a range of cast iron discs sized appropriately to increase resistance to the thermo-mechanical stresses that occur on heavy vehicles. For critical applications such as industrial vehicles, Brembo uses its exclusive pillar venting technology, developed and patented by the group’s Research and Development Centre.
Compared with discs from other manufacturers, Brembo discs with pillar venting technology improve material distribution, increase heat exchange surface area and produce greater air turbulence in the ventilation gap. All of these factors significantly contribute to reducing cooling times and minimizing thermal cracks.
In commercial and professional vehicles, the parking brake must be absolutely safe, reliable and simple to use at all times. Brembo supplies mechanical and electrical parking brake systems. The first one may either be integrated in a combined with a caliper or drum, or isolated in DIH (drum in hat) installations, to provide the ideal solution to the many different needs and demands of different commercial vehicle manufacturers. The mechatronic solution (electric parking brake), for vehicles up to 7.5 tons, will supply a vehicle for the first time starting from 2019.
