Yamaha Motor: a look dedicated to ABS [VIDEO]

The system ABS is the central topic of a new Tips and Tricks event proposed on the Facebook page linked to yamaha Motor.

The argument

Marco Risso, technician of yamaha Motor for over 20 years, it has summarized one of the most interesting and now widespread innovations for the safety of travellers. An acronym linked to a German expression meaning: “Anti-blocking system”. An integrated device, it is underlined on this occasion, which prevents the wheels from locking when braking.
Whatever your driving attitude, more or less aimed at fun, this video highlights some key aspects of the system. A solution which, for example, is not present by regulation in MotoGP, therefore it is not discussed in the premier class precisely because it is not possible to adopt “no electronic braking management system”. In this case, a rider's sensitivity is even more effective and functional on dry surfaces, a slightly different matter on wet surfaces.
Shifting attention to the mechanics, when braking the prepared fluid is brought under pressure by a pump, which in turn produces pressure on the brake pads. In an ABS system, therefore, the liquid passes through a hydraulic unit or also called “ABS unit”, controlled by a specific electronic control unit. Based on the inputs coming from the speed sensors combined with the wheels, if the control unit perceives a tendency for the wheel to lock, it activates a valve inside the aforementioned hydraulic unit. Through this, some oil flows out and the pressure on the brake caliper drops, avoiding locking, as mentioned. Then, when the control unit senses a normalization of speed from the wheel, it tightens the valve again and thus stabilizes the normal pressure on the braking caliper.
Speaking of the old ABS systems, the valves were larger and offered action “on/off”. Basically they were open or closed. They were noticeable during braking “oscillations” on the brake lever, due precisely to the pressure levels. Today, however, the systems are more advanced and compact, equipped with “linear control valves” is “partialize” the passage of oil, as highlighted by the technician, with short braking distances. An aspect to consider with the variability of conditions present on the roads. Advice is also provided on this occasion.
