The research on vehicle dynamics contributes significantly to the development of the automotive industry. It has been conducted for many years by various research centres which use their own or commercial research stands. Purchasing a commercial mobile stand offered on the market is a serious financial problem. Additionally, it does not always give possibilities to measure all relevant parameters. Therefore, there was developed an own solution of such a device which is the subject of this publication. The paper presents a structure solution of only one of the modules constituting a mobile stand for testing the dynamics of a vehicle movement. The described module is a head used for measuring the steering angle and angular velocity of a wheel. It is an original, non-applied solution which allows to measure the actual steering angle of a vehicle. The advantage of the presented solution is that a simple design allows for a quick assembly and disassembly of the device in any vehicle by only one person. The stand was made at the Department of Vehicles and Fundamentals of Machine Design at the Technical University of Lodz. The attempts of assembly of the stand and tests on various passenger cars proved its practicality and possibilities of achieving the assumed research on the dynamics of vehicle movement.
