    摘要:

    為提高聯(lián)合收獲機的機動性和工作效率，設計了由濕式摩擦片離合器傳遞反轉(zhuǎn)動力的原地轉(zhuǎn)向行走變速器并進行試驗研究。結果表明：正、反轉(zhuǎn)動力轉(zhuǎn)換柔和傳遞可靠，理論轉(zhuǎn)向半徑為零；與傳統(tǒng)單邊制動轉(zhuǎn)向機構相比，作相同角度轉(zhuǎn)向時，轉(zhuǎn)向行程比后者下降了50%，轉(zhuǎn)向功耗比后者下降41.43%，并減輕了對田間地表的破壞。原地轉(zhuǎn)向技術的應用，可減少田間作業(yè)空行程，提高機器機動性，從而提高了聯(lián)合收獲機的整機技術水平。

    Abstract:

    In order to improve flexibility and operation efficiency of combine harvester, a pivot steering transmission was designed and tested. A clutch system with wet friction plate was used to transmit the positive and negative power Results showed that the exchange between forward rotation power and reverse rotation power was soft and reliable. Theoretical turning radius of combine harvester was zero. When steering at the same angle, the turning stroke and power consumption were reduced by 50% and 41.43% respectively, compared with traditional turning mechanism in one side brake. It could also reduce the damage to soil. The pivot steering transmission could reduce the idle stroke of field working and improve intelligence of combine harvester.
