Abstract
In this thesis, an investigation is done about the possibility to integrate electronic push brakes on a bicycle trailer. The bicycle trailer is a multifunctional trailer used when running, bicycling, or skiing. By conducting a concept developing process, this investigation aims to build a full-scale mock-up, that can be used as a proof of concept. The problem is divided into four sub-problems; brakes, manipulation of brakes, sensors, and electronics. Concerning the brakes, the results show that the pre-existing disc brakes on the trailer, which are provided to be used for run- ning, are strong enough according to the established specifications. Regarding the manipulation of brakes, the final concept presented in this thesis is a lead... (More)
In this thesis, an investigation is done about the possibility to integrate electronic push brakes on a bicycle trailer. The bicycle trailer is a multifunctional trailer used when running, bicycling, or skiing. By conducting a concept developing process, this investigation aims to build a full-scale mock-up, that can be used as a proof of concept. The problem is divided into four sub-problems; brakes, manipulation of brakes, sensors, and electronics. Concerning the brakes, the results show that the pre-existing disc brakes on the trailer, which are provided to be used for run- ning, are strong enough according to the established specifications. Regarding the manipulation of brakes, the final concept presented in this thesis is a lead screw- based concept for transferring rotational- to translational motion. The concept uses stepper motors for position control of the lead screw which allows for controlling the braking torque. The results show that this concept enables the disc brakes to produce enough torque to meet the specifications. Lastly, for the sensor model, an accelerometer was considered. The idea was to sense a brake event based on the acceleration data and brake correspondingly on the trailer. However, even though the result indicates that it is possible to sense break events, this approach introduced control problems and the conclusion is that another sensor measuring force between the bicycle and trailer is needed.
