Design of a parking brake for vehicles powered by an electric motor
 Kolčava, Jiří ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This diploma thesis deals with issues in the field of latch parking brakes, specifically the control mechanism. The key element of the work was the structural design of this mechanism, which converts the rotary movement of the electric motor into the translational movement of the control member enabling the latch to be inserted and extended from the latch wheel. The research part describes the main components of the mechanism and a description of individual types of control. This is followed by the creation of four conceptual designs and the selection of the optimal solution using the method of weighted coefficients. The structural part contains analytical strength calculations of the chosen conceptual design, including the solution of the kinematics of the mechanism. This part also deals with the analysis of the torque from the activation spring depending on the rotation of the crank mechanism and the subsequent optimization of the electric motor. In the end, the analytical strength calculations of selected structural units are verified by FEM analysis to confirm the functionality of the mechanism.
