ABSTRACT
The article deals with the analysis of possible causes of vehicle yaw during braking as one of the phenomena affecting passenger safety. The braking diagram of the vehicle and the change in vehicle deceleration during the braking process are analyzed. Based on the analysis of the wheel brake mechanism's structure, the identification of the number and location of redundant constraints, their possible influence on the mechanism's operation and braking process, is demonstrated. Notably, the existing redundant constraints can cause an abnormal load, leading to the operation of parts with unintended preloads and tensions, and thereby reducing the service life of brake parts and compromising the safety of the vehicle braking process. Using constructive methods by changing the structure of the mechanism, adding kinematic pair motions and using kinematic connections, three variants of new brake mechanism designs are proposed, which reduce the number of redundant links and can have a significant positive influence on brake operation.
