摘要
汽車轉向系統(tǒng)分為機械式轉向系統(tǒng)和動力力式式轉向系。其中動力式的是在機械轉向器基礎上發(fā)展的。
動力轉向系統(tǒng)是一套兼用駕駛員體力和發(fā)動機動力為轉向能源的轉向系統(tǒng)。在正常情況下，汽車轉向所需的能量只有一小部分由駕駛員提供，而大部分能量由發(fā)動機通過轉向加力裝置提供。但在轉向加力裝置失效時，一般還應當能由駕駛員獨立承擔汽車轉向任務。因此，在今天，動力式轉向系統(tǒng)因其優(yōu)良的穩(wěn)定性和可操作性開始壟斷市場。而滑閥式常流液壓動力轉向器由于其結構簡單，造價低，泄漏較少，消耗功率較小等優(yōu)點曾被廣泛應用。例如斯達-斯太爾91系列、CQ30290、黃河地盤等均采用滑閥式常流液壓動力轉向器。
因此，本設計將針對重型載貨汽車，進行滑閥式常流液壓助力轉向系統(tǒng)的結構設計計算。
關鍵詞：重型貨車；滑閥；常流液壓；助力轉向；結構設計
Abstract
Automotive steering system is divided into mechanical power steering system and power steering system type. 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.
Key words: Heavy goods vehicles; slide valve; constant flow hydraulic; power steering; structural design
