Is there an ABS system on a motorcycle?
There are ah! Now casually 8 9 thousand domestic motorcycle have ABS!
Car ABS can not be copied to the motorcycle, because the motorcycle space is extremely limited, so ABS also "do as the Romans", to change the volume and structure to meet the needs of motorcycles. Take the ABS device of Yamaha motorcycle as an example. (The engine next to the side); two sets of sensor components placed in parallel on both sides of the wheel, responsible for monitoring and feedback wheel rotation of the subtle changes; ABS electronic control unit (the engine is the most important parts of the hydraulic control valve ECU) placed in the rear (under the seat cushion), responsible for handling the sensor feedback information and issued a command signal, control the hydraulic control valve to increase or decrease the brake hydraulic pressure. When the ECU found that the wheel has been locked (slip) phenomenon, immediately react, so that the hydraulic control valve solenoid valve open, so that brake fluid reflux storage room, wheel brake pressure drop; when the wheel rotation is accelerated, ECU And instructed to re-close the hydraulic control valve, forcing the brake fluid out of the reserve room back to the brake clamp cylinder, the wheel brake pressure increases, the wheel rotation slows down. Its hydraulic changes can be completed in a tenth of a second, that is, instant wheel brake repeatedly retractable, will not be locked.
