Sensors for safe driving a car significance. Evonik production VESTAMID L1930 polyamide 12, is headquartered in Germany, Valeo Schalter und Sensoren GmbH has selected as the steering angle sensor gear mechanism materials to ensure smooth and safe vehicle capable of driving in the dark, winding or slippery The pavement.
 
Turn the steering wheel steering angle sensor measuring the degree, and continued to pass the driver's direction of travel to the dynamic stability control system - namely, electronic stability control systems or ESC. ESC will expect the traveling direction of the driver and the actual direction of the vehicle are compared, use to make the necessary adjustments to the orientation direction of the brake on each wheel. This has many benefits, such as preventing the vehicle on a curve can be accelerated to ensure that the driver control of the vehicle.
 
A sensor mounted on the steering column, a steering drive gear comprises a rotor, and a rotor driven by two different teeth of the pinion (vernier caliper principle). Magnets embedded in the gear inside to take advantage of a Hall or magnetoresistive angle sensor detects the rotational orientation of the gear. Angle sensors provide electrical signals in turn can help to calculate the absolute steering angle of the vehicle. Materials for gearing must meet strict requirements to ensure that the steering angle sensor of high accuracy and durability, and to maintain the necessary accuracy angle.
 
VESTAMID L1930 product exactly have these features: as a polyamide 12, which can take place over a wide temperature range (-40 ℃ -125 ℃) stable physical properties with only minor changes in different humidity; molding almost no dimensional changes.
 
The material even in subfreezing also has a very high impact resistance and notch (notched) impact strength, and has good resistance to oil, fuel, hydraulic oil and salt solution resistance, making it ideal for automotive applications. Its excellent wear resistance and low coefficient of sliding friction of the steering angle sensor gear is very important, but it can also noise damping.
 
VESTAMID series products have been widely fifty years many well-known manufacturers in the automotive industry use. Sustainable development so that it can be applied to more and more areas, from the line system (piping system) to the cable sheath, to a very small injection molded parts.
