Konstruktion av broms till motståndsvagn
Sammanfattning: Baltic fitness, which is the project owner, is a company that invests in Swedish-made training equipment. This work has been about constructing a resistance brake for a weight-bearing resistance sled, consisting of a chassis on wheels and four handles. Resistance sleds are often used for training purposes where the practitioner pulls or pushes the handles. In order for the exercise to have maximum effect the carriage must have some type of braking function that gives more resistance to the work and makes the work heavier. A preliminary study initiated the project to investigate various brake types and resistors used in vehicles and training equipment. Concepts for the brake function were designed with regard to the carriage construction and the requirements set by the project owner. Calculation have been made to ensure that the braking function creates sufficient resistance. The final result was two concept proposals, a magnetic resistance brake that acts like an electromagnetic retarder in heavy vehicles, without mechanical friction. The second concept is an electric resistance brake where an electric motor acts as a generator and a high load resistor loads the motor shaft.
