Research and innovation as growth "engine"
Hutchinson is permanently searching for innovative technical solutions. Each question raised by a manufacturer or an automotive equipment supplier is seen as a new challenge to be met head-on. With access to significant development resources (especially digital simulation), the companies owned by Hutchinson are also able to benefit from the skills and expertise of the Montargis Research Centre in France. As a world leader in industrial rubber manufacturing, Hutchinson is currently using several alternative technologies: elastomer thermoplastics and metal parts (steel, aluminium, etc.).
Noiseless belt in EPDM
Hydraulic dampening linear tensioners
In the accessory drive system of a thermal engine (automobile, HGV, agricultural, marine, etc.), it is necessary to guarantee a minimum tension of the belt and to limit the effects of the latter's vibration and slipping. This is why is may be necessary to use automatic tensioners. This makes it possible to eliminate all types of harmful effects such as tolerance of shape and position of the accessories (pulleys, rollers...), the dynamic extension of the belt, the wearing of the belt, unevenness (cyclical irregularities of the engine) or transient phenomena (start-up/stopping of the engine).
The elastic STRETCHY BELT®
The STRETCHY BELT® boasts a degree of elasticity that guarantees the correct tensioner without the need to add a tensioner. This technology results in major savings on the cost of the function and its spatial requirements (engine is more compact), as well as in a reduced weight of the entire system, which in turn has a positive effect on the vehicle's fuel consumption. The STRETCHY BELT® also has the ability of absorbing dynamic tension peaks related to unevenness (cyclical engine irregularities) and to the commissioning (or decommissioning) of accessories such as the alternator, the air-conditioning compressor, etc. This results in vibrations and therefore in the noise level of the system.
Active anti-vibration disengagement
Its latest generation active supports are used on top-of-the-range vehicles (first application on BMW 5 series) and is gradually being used more by all manufacturers.
Multi-axed vibration disengagement
Barrier films in the fuel and air-conditioning pipes
Elastomer-based pipes have incomparable flexibility. Nevertheless, theses are permeable to gasses, especially petrol fumes or coolant liquid in the vehicle air-conditioning systems. To address this issue, Hutchinson has developed pipes with thermoplastic films that act as "barrier" layers and prevent the effusion of the gasses.
Mecatronics of the magnetic measurement systems
Hutchinson Paulstra is developing magnetic coding systems based on charged polymers, used for measuring speed, travel or position. These products can be used for linear measurement or in rotation with regards to exposed or contained applications: coding seal for ABS, for example. Their characteristics give them a significant advantage in terms of thermal, chemical (aggressive fluids) and mechanical (shocks, accelerations, vibrations) resistance, as well as a high level of precision and reliability.
