2、  摘 要履帶車輛的轉(zhuǎn)向機(jī)構(gòu)是重要的總成之一，其性能的優(yōu)劣直接影響著車輛的轉(zhuǎn)向機(jī)動性和生產(chǎn)效率。因此對性能優(yōu)良的轉(zhuǎn)向機(jī)構(gòu)的研究一直是車輛工程領(lǐng)域的重要研究課題。履帶式工程機(jī)械的轉(zhuǎn)向機(jī)構(gòu)普遍采用單功率流的轉(zhuǎn)向離合器和制動器，兩者相配合，使兩側(cè)履帶以不同速度行駛，實現(xiàn)轉(zhuǎn)向。這種結(jié)構(gòu)非常簡單，同時也易于實現(xiàn)轉(zhuǎn)向，但是要實現(xiàn)小半徑轉(zhuǎn)向時需借助摩擦元件的打滑來實現(xiàn)，造成嚴(yán)重的功率浪費，降低摩擦元件的使用壽命。同時駕駛操作費力，還不好準(zhǔn)確把握車輛的轉(zhuǎn)向半徑。本設(shè)計為推土機(jī)設(shè)計采用的一套動力差速式轉(zhuǎn)向裝置。該轉(zhuǎn)向機(jī)構(gòu)主要包括一個轉(zhuǎn)向差速機(jī)構(gòu)、一個液壓泵、一個液壓轉(zhuǎn)向馬達(dá)和轉(zhuǎn)向控制器，它將轉(zhuǎn)向和差速

3、和為一體，簡化了機(jī)械的結(jié)構(gòu)，提高了機(jī)械的使用性能。該機(jī)構(gòu)具有差速的同時，還具有差速鎖的效果，并具有降速增扭的功能，大大提高了履帶車輛行駛通過性和轉(zhuǎn)向性能。關(guān)鍵詞：差速式轉(zhuǎn)向機(jī)構(gòu)；轉(zhuǎn)向離合器；轉(zhuǎn)向半徑；履帶車輛；轉(zhuǎn)向控制器ABSTRACTThe steering mechanism of tracked vehicle is one important part of the unit, and itsperformance will directly affect the mobility and productivity of the vehicle.
