| Popis: | The principles of functioning of stands for testing the braking qualities of wheeled vehicles are considered. Their advantages and disadvantages are analyzed. There is a general disadvantage of the most common power brake roller stands in practice – the difference in the shape of the contact spot and the acting forces and reactions of the wheel on the support rollers and in road conditions. As a result of the system analysis of structures, a modified method and design of a power roller stand with an original support device in the form of a horizontally rotating disk are proposed. The description of the principle of implementation of tests on braking qualities and suspension of vehicles is given. A preliminary analysis of the proposed stand design shows that in a static state, the wheel contact spot on such a disk is completely identical to the wheel spot on a horizontal road surface. When the disc rotates and the brake system is tested, the shape of the wheel contact spot on the support disc will change, but, according to the authors, slightly – similar to how the contact spot changes during the curvilinear movement of the car, characteristic of real operating conditions, but how much this will happen is the subject of further research. Purpose – development of a method and design of a stand that provides an increase in the reliability of testing the braking qualities of cars under operating conditions. Methodology system analysis of methods and designs of stands for testing braking qualities and suspension of vehicles, elements of block-modular design. Results: a patentable design of a power stand is proposed, free from the disadvantages of power roller brake stands. Practical implications the obtained results should be used in the creation and production of brake stands for monitoring the technical condition, when diagnosing and conducting technical inspections of vehicles under operating conditions. |
