One type is the mechanical power steering on the basis of development. Power steering systems use either a driver's manual and engine power steering system for the transition energy. Under normal circumstances, the vehicle steering the energy required only a small part of the offer by the pilots, and most of the energy from the engine through the steering afterburner devices provide. However, in turn afterburner device failure, the general should also be able to bear the steering by the driver of independent tasks. So, today, power steering system, because of its excellent stability and maneuverability is beginning to dominate the market. The slide-valve-type constant flow hydraulic power steering because of its simple structure, low cost, leak less, consume less power etc. have been widely used. For example, Star - Steyr 91 series, CQ30290, the Yellow River site Dengjun using slide-valve type constant flow hydraulic power steering. Therefore, the design for the heavy-duty truck to carry out regular flow of slide-valve-type hydraulic power steering gear design calculations.
