| In order to improve brake capability of medium-price and low-price motorcycles, a kind of economical and practical Anti-Lock Brake System (ABS) and its testing system need to be researched and developed urgently at present. This paper narrated the principle of motorcycle anti-lock brake control, provided the calculating method of controlling parameter and derived a formula about the braking pressure and friction factor of real road conditions. A mechanical motorcycle anti-lock brake controller was contrived and the series-design theory was completed on the basis of this formula; the construction parameters and design of nonlinear-spring were also addressed. The construction of testing system was designed and controlling principle was narrated. The input and output pressure of the controller were tested statically and dynamically under high μ, mid μ and low u conditions and real road conditions in computer routing, the controller satisfied two goals: delay and reduce the peak of braking pressure and produce superior braking distance. This controller has three virtues: the novel construction, the convenient for installation and the competitive price. Now it is in a small batch production and it will have a brisk market prospect. |
