| Sumario: | Mekara Electric Vehicle 02 is
a type of city car that converts conventional vehicles into electric vehicles
at the Universitas Indonesia. The brake booster component system still uses a type of vacuum
brake booster. The
brake booster is a component in the brake system that reduces the force on the
driver's pedal in the vehicle braking process. The vacuum brake booster
requires a vacuum generated by the engine intake manifold. In an electric car,
there is no vacuum in the intake manifold because the engine is changed by an
electric motor. The use of a vacuum brake booster in electric cars requires an
additional component of a vacuum pump. The use of a vacuum pump on a vehicle
battery requires electricity consumption of 3.9 Watt hours. In this study, we
aim to design a new electric brake booster mechanism as
a replacement for the vacuum brake booster mechanism. We used our proposed
method to design an electric brake booster component and make a prototype. The
prototype was tested using a rig test simulation. The electric brake
amplifier applies the magnetic force generated by the solenoid and pulls the
lever bar connected to the brake master. The brake pedal that is stepped on by
the driver activates the flow of electricity on the solenoid and activates a
magnetic pull force so that the driver's force in pressing the brake pedal will
be assisted by an electric brake booster mechanism. Electric
brake boosters can reduce electricity consumption by 28.2%. |
