Fékegységek

Fékegységek, in the context of automotive engineering, refers to the collective term for the components that constitute a vehicle's braking system. The primary function of fékegységek is to slow down or stop the vehicle by converting kinetic energy into heat through friction. A typical fékegység includes the brake pedal, master cylinder, brake lines, brake fluid, and the actual braking mechanisms at each wheel.

At the wheels, fékegységek can be either drum brakes or disc brakes. Drum brakes, historically common, consist of a rotating drum attached to the wheel hub and brake shoes positioned inside the drum. When the brakes are applied, the shoes are forced outward against the inner surface of the drum, creating friction. Disc brakes, now more prevalent due to their superior performance and heat dissipation, comprise a rotor (disc) that rotates with the wheel and a caliper that houses brake pads. When braking, the caliper squeezes the pads against the rotor.

Modern vehicles often incorporate advanced fékegységek such as Anti-lock Braking Systems (ABS), which prevent wheel lock-up during heavy braking, and Electronic Stability Control (ESC), which uses braking to help drivers maintain control during skids. The proper maintenance and functioning of all fékegységek are crucial for vehicle safety.
