【正文】 ull play to its highspeed driving performance and to ensure that the momentum on security. Evidently, this braking system design of practical significance. For the design of Foton View Light Bus,First developed structure of the braking system, the design determined by preand postdrum brakes, dualchamber tandem brake master cylinders, HHcrossline layout. This was followed by calculation of the main braking system design parameters (attachment coefficient determined simultaneously, the braking force distribution coefficient, the biggest brake brake torque), the main parameters of design and brake hydraulic drive system parameters. Drawing once again use puteraided design assembly drawing, layout plans and parts. Final braking force distribution of programming, the design of the braking system of indicators to evaluate the analysis. Through this design calculations designed to show that the braking system is reasonable, in line with standards. To meet its structure is simple, low cost, reliability requirements.
