Theoretical Research on Ideal Brake Force Distribution of Tractor-semitrailer Cornering Braking
For tractor-semitrailer,load transfer during cornering braking caused big difference of the vertical load between coaxial wheels.As a result,braking efficiency and directional stability were affected seriously,the traditional design of braking force distribution between axles couldn’t meet the requirements.In this paper,a dynamic model of tractor-semitrailer was established according to the motion and force during cornering braking.The rule of vertical load changing of each wheel with longitudinal acceleration and lateral acceleration was obtained.Combining with the tire and road adhesion conditions,the ideal brake force distribution was achieved.The research could provide theoretical reference to better control strategy of tractor-semitrailer braking control system.
