rumpulipasjärjestelmä
Rumpulipasjärjestelmä refers to a drum brake system, a type of brake used in vehicles. In this system, the braking mechanism consists of brake shoes that press outward against the inner surface of a rotating drum. This drum is attached to the wheel. When the brakes are applied, a hydraulic system forces the brake shoes against the drum, creating friction. This friction converts the kinetic energy of the rotating wheel into heat, slowing down the vehicle. Rumpulipasjärjestelmä is a common braking technology, particularly in older vehicles or as a parking brake mechanism in some modern cars. The drum itself typically houses the brake shoes and a wheel cylinder, which contains pistons that push the shoes outward. The efficiency of a rumpulipasjärjestelmä depends on factors such as the material of the brake shoes and drum, their condition, and the adjustment of the system. While disk brakes have become more prevalent due to their superior heat dissipation and performance, drum brakes remain a cost-effective and reliable solution for certain applications.
