具有用于轮毂平移的带花键法兰的变速箱同步器
Abstract:
一种变速箱(BV)，所述变速箱包括输出轴(AS)，所述输出轴具有同步器(SB)，所述同步器包括：法兰(FL)，所述法兰包括与所述输出轴(AS)固定地连成一体的副轮毂(SM)并且具有外花键(CE3)；轮毂(MO)，所述轮毂包括内花键(Cl1)，所述内花键与所述副轮毂(SM)的外花键(CE3)配合，以用于能够使所述轮毂相对于所述副轮毂(SM)平移；以及套筒(MA)，所述套筒能够相对于所述轮毂(MO)平移，以便所述套筒的内花键(Cl2)与空转齿轮(PF1)的牙(CR)紧密联结。轮毂(MO)相对于副轮毂(SM)的该平移独立于所述套筒(MA)和所述空转齿轮(PF1)的制造尺寸变化地确保所述套筒(MA)的内花键(Cl2)与所述牙(CR)紧密联结并且具有最小化平移幅度。
Abstract(English):

A gearbox (BV) comprises a secondary shaft (AS) provided with a synchromesh (SB) comprising a flange (FL) comprising a sub-hub (SM) fixedly secured to the secondary shaft (AS) and provided with external splines (CE3), a hub (MO) comprising internal splines (CI1) collaborating with the external splines (CE3) of the sub-hub (SM) to allow translational movement with respect to the latter (SM), and a sleeve (MA) that can undergo a translational movement with respect to the hub (MO) so that the internal splines (CI2) thereof are closely coupled to dogs (CR) of an idling pinion (PF1). This translational movement of the hub (MO) with respect to the sub-hub (SM) guarantees close coupling of the internal splines (CI2) of the sleeve (MA) with the dogs (CR) with a minimal margin for translation, irrespective of dimensional variations in the manufacture of the sleeve (MA) and idling pinion (PF1).
