Drum Brake Unit

INTRODUCTION

Current industrial requirements need increasingly advanced safety systems adapted to every machine requirements.
One of the most important features of all cars as basic equipment is the brakes, one of the most important safety systems in a car (even the most important one), essential for the driver safety, since they are the main means of protection in the road.
The brake system helps to decrease the speed and stop the vehicle, therefore it must work accurately.
There are two types of braking systems in a car: drum brakes and disc brakes.
Drum brakes are located in the wheel itself. They were used in the first cars, but from the 60s and 70s on they were replaced by disc brakes in the front shaft.

EXERCISES AND PRACTICAL POSSIBILITIES

1. Understanding of a drum brake.
2. Brake study with primary and secondary shoe.
3. Study of the coefficient of friction
4. Study of the braking difference of the primary and secondary shoe.
5. Study of different brake configurations.
6. Calculation of the reactions in the supports
