变速箱的互锁机构可防止同时挂上两个档。泰山—12拖拉机变速箱有两根变速轨,变速轨端部环槽处两根轴之间有一个互锁销,互锁机构工作原理如图所示。互锁销长度等于两根变速轨槽底间距h减去一根变速轨槽深(图a),这样移动任一根变速轨,锁销就把另一根变速轨卡住(图b),实现互锁。我们在实际工作中发 The gearbox interlock prevents the two gears from hanging up at the same time. Taishan -12 tractor gearbox has two speed rails, speed rail at the end of the groove between the two axes have an interlock pin, interlock mechanism works as shown. The length of the interlocking pin is equal to the distance h between the bottom of the two transmission track grooves minus the depth of one of the transmission rail grooves (Fig. A), so that any one of the transmission rails is shifted and the locking pin catches the other transmission rail (Fig. B) To achieve interlocking. We send in the actual work
