Angle Gear Drive at it's best!
Efficient angle gear drive for your side-mounted engine cooling system.
Does your thermal management system in the commercial vehicle require a highly efficient fan drive, particularly, in terms of tightened exhaust gas regulations? Our angle gearbox is an important module in this system.
It is not only space-saving and energy-efficient, but also convincing in terms of performance and smoothness. Our angle gearbox takes place in a drive segment where precision is important in all speed ranges.
Kendrion's angle gearbox convinces with its impressive compact and weight-optimized design. It enables lateral radiator installation in buses and coaches, allowing for flexible and efficient layout of the cooling system. Powered by the engines belt drive, the use of angle gearboxes allows for otherwise additionally required components, such as pumps, valves or hosing packages, to be omitted. The installation effort as well as the activation and control are reduced to a minimum, along with the costs. We're talking 'pure mechanical power transfer from the engine's belt drive to the fan'. Compared with all other clutch technologies on the market, Kendrion realizes the highest efficiency for fan clutches.
When combined with a two- or three-speed fan clutch, which can be positioned either upstream or downstream of the angle gearbox, you're looking at a compact system solution providing fuel savings and high efficiency. Kendrion's angle gearboxes of the LINNIG brand are used worldwide under any imaginable operating conditions
