Question

Q- A study by the Swedish Road Administration resulted that 59 % of all severe and fatal motorcycle accidents could be avoided by the use of anti-lock braking (ABS) systems. As a consequence, the European Union (EU) passed legislation that made ABS systems compulsary on all new motorcycles sold in the EU from 2014 onwards. Based on recent published fatality figures, this is predicted to save thousands of lives every year, including hundreds in the UK. ABS systems ensure that the wheels do not ‘lock up’ (i.e. stop rotating), during braking, while the motorcycle is still in motion. Briefly explain why this is important from a motorcycle safety and maintenance point of view.

Ans constant ܝܘ individual lever Na5 any the with A BS1 there The Anti lock Braking systems (ABS) berevents the locking of the wheels of bike when brakes are applied by the rider. This prevention of locking measurement of the individual wheel speed and then by compairing it with the wheel speeds predicted by this system. The measurement of speeds by speed Sensors. In the earlier models of Bikes with out ABS, the of the brake directly coronected with the caliper The Jonce applied by the rider on the lever is directly exerted on caliper and disc without interrupt in bikes without ABS. But in the bike models equiped an additional rechanism sisting of Electronic control unit and Hydraullic valve. So, due to this control mechanism, if during the application brakes meas wred speed of the wheel differs from the predicted speed by the system, this control mechanism takes over it wirects the brake force so as to keep the wheel at optimum slip level and thereby achiening the highest possible Deacleration make. This Electronic control unit is a programable unit which avoides the rotational speed of the wheel to Zero Rotational speed means Locking.
