摘要
商用车变速箱低挡同步器由三挡向二挡减挡,时常表现为换挡力大和换挡时间长等问题,DF6S900、DF6S720、DF6S650、DF5S550、DF5S470等多款现有主力商用车变速箱都存在低挡同步器动态换挡力重的问题,这主要是因为二挡单锥同步器同步容量偏低引起的,近几年,国内外多家研发机构都加大了对商用车变速箱低挡同步器的研发力度,为国内众多变速箱生产企业提供解决办法,多种结构的双锥同步器开始投入使用。对变速箱低挡同步器关键参数的优化设计进行了介绍,并通过相关试验对其给予验证,得到优化设计的实际价值,为推广提供支持。
Commercial vehicle lowgrade SYN transmission reduce gear from 3rd to 2nd, always appears some problems, such as shift force hard, shift time long and so on. DF6S900, DF6S720, DF6S650, DF5S550, DF5S470 and other main commercial vehicle transmission all have the problems of low - grade synchronizer dynamic shifting force hard, this is mainly because of the low capacity of the 2nd single cone SYN. In recent years, at home and abroad many R＆D institutions increase the R＆D power of commercial vehicle transmission low - grade SYN to, provide solutions for domestic large transmission manufacturing enterprises, a variety of structures of double cone SYN come into use. The optimization design of key parameters of low - grade SYN transmission is introduced, and through the relevant test this is verified, optimized design is valuable for promotion.
