摘要： A synchromesh device for a transmission of an industrial truck such as a fork lift truck includes a main shaft, forward and reverse change gears, synchronizing hub fixed to the main shaft by means of spline grooves, a coupling sleeve axially slidably engaged with spline grooves formed in the outer circumference of the synchronizing hub, and balk-rings formed in their inner surfaces with conical surfaces facing to conical surfaces formed in the side of a clutch gear integral with the forward change gear and of a clutch gear integral with the reverse change gear, respectively.According to the invention, conical angles of the conical surfaces are more than 10.degree. and preferably less than 11.degree., thereby reducing surface pressures acting between the synchronizing slide surfaces during the synchronization to improve the durability remarkably.
摘要翻译：用于诸如叉车的工业车辆的变速器的同步啮合装置包括主轴，正向和反向换档齿轮，通过花键槽固定到主轴的同步轮毂，与所形成的花键槽轴向滑动地接合的联接套筒在同步轮毂的外周和形成在其内表面上的阻挡环，其锥形表面面对形成在与前变速齿轮一体的离合器齿轮的侧面上的锥形表面，以及与倒档齿轮成一体的离合器齿轮，分别。根据本发明，锥形表面的锥角大于10°，优选小于11°，从而减少同步期间作用在同步滑动表面之间的表面压力，从而显着提高耐久性。
