MAIN COMPONENTS OF ABS
ABS is a electronic control system consists of
Modulator (Modulator Consists of Electronic control
unit + Modulator valve + Pump ) Polo wheels, Speed
Sensors, and connecting cables.
WHEEL SPEED SENSOR
The main use of a speed sensor is to monitor the speed
of the wheels in the vehicle. ABS speed sensors are
located at the Front fork lug and Swingarm mounting
of the vehicle. These sensors constantly monitor the
rotation of each wheel to evaluate whether the ABS
system needs to override manual braking of the
vehicle in slippery conditions. The speed sensor
calculates revolutions as well as evaluates continuity
between all wheels. Any detection of differences in
rotation can result in ABS engaging to control braking.
Speed sensors convert the pulses created by the
contact between the magnet and sensor ring through
a coil attached to the sensor. This voltage is passed
along to the controller. The controller counts the
number of pulses to determine wheel speed and
evaluates whether the ABS system should intercede
to control braking.
HOW ABS WORKS
1. Rider Pushes Brake Pedal
2. Piston Pushes Brake Fluid
3. Brake Fluid squeezes brake pads onto brake disc.
