ABS System in Bikes

Posted by tan xiao yan on

From Wikipedia, you can get a general knowledge about ABS System. General speaking, it is used in motor vehicles to brake in the emergency. In recent years, some bicycle-makers gradually apply ABS system to bikes. It is good news to cyclists, perhaps. But bicycles installed ABS system cost much more than ordinary ones.

ABS system stands for the anti-lock braking system or anti-skid braking system. It is an automobile safety system. It allows the wheels on a motor vehicle to maintain tractive contact with the road surface according to driver inputs while braking hard. Hence prevent the wheels from locking up (ceasing rotation) and avoid uncontrolled skidding. This automated system uses the principles of threshold braking and cadence braking which were practiced by skillful drivers with previous generation braking systems. It does this at the much faster speed and with better control than many drivers could manage.

ABS generally offers improved vehicle control and decreases stopping distances on dry and slippery surfaces. However, on loose gravel or snow-covered surfaces, ABS can significantly increase braking distance, in spite of still improving vehicle steering control.

Since primary widespread use in production cars, anti-lock braking systems have been improved considerably. In recent years, this system versions can not only prevent wheel lock under braking but also electronically control the front-to-rear brake bias. This function, relying on its specific capabilities and implementation, is known as electronic brake force distribution (EBD), traction control system, emergency brake assist, or electronic stability control (ESC).

An ABS System comprises of these components:

Wheel speed sensors: detects the latent wheel lock and sends the signals to ECU. ECU stimulates the valves, motor, pump on the base of the inputs from wheel speed sensor.

Brake calipers: lower down or stop vehicles speed via piston motion.

Hydraulic unit: comprises of kinds of hydraulic components such as the pump, valves, accumulators along with a Motor.

Pressure release valves

A fast working computer harmonizes the entire process.

How ABS works

On detecting one wheel stopped rapidly all of a sudden, ABS will automatically reduce the braking stress on the wheel right now via opening a pressure release valve in the hydraulic system. ABS can also put the pressure back up through the hydraulic motor. The system reacts fast. It works just on the front wheel (which does most of the braking work).

So far, you must have had a better understanding of ABS system. Most cyclists might experience braking hard. As a result, many of you may fall down, jaws kissing the earth, or turning a back-somersault in. Now that ABS system can deal with braking work in the case of an emergency, why don't bicycle-manufacturers install it on the bikes? Some factories bring good news. First things first, let's get a further more information about its function.

Get full use of braking efficiency so as to shorten braking time and distance;

Prevent effectively vehicles from side slipping and going into a "snap". Ensure great stable rideability;

Easy to steer under the emergency braking circumstances;

Avoid excessive friction between the tire and the earth, allaying tire wear;

Prevent the wheel lock up due to an emergency situation.

ABS System is invented to avoid slipping or losing control of steering in the emergency. This invention is beneficial to all over the world. It denies the accidents caused by deadlock when bicycles turning and biking at a high speed. This production has the advantages of small size and simple assembly. Thus customers can purchase and install it on their own.

A bicycle installed ABS System is very promising. It promotes the low-carbon lifestyle. People who get used to driving cars or the old can ride the bicycles in that it is easier to learn. More importantly, bikes are safer.
