一种单双级行星齿轮组合式六挡自动变速器
摘要：
本发明公开了一种单双级行星齿轮组合式六挡自动变速器，包括由前排行星架(6)、前排行星齿轮(7)、前排太阳轮和前排齿圈构成的前排单级行星齿轮机构，由中排行星架(13)、中排第一行星齿轮(11)、中排第二行星齿轮(10)、中排太阳轮和中排齿圈构成的中排双级行星齿轮机构，以及由后排行星架(15)、后排行星齿轮(17)、后排太阳轮(16)和后排齿圈(18)构成的后排单级行星齿轮机构。本发明的自动变速器具有结构简单紧凑、加工零件类型少、成本低、执行元件少、换挡时执行元件变换少、不易运动干涉的特点。
摘要（英）：

The invention discloses a single-stage and double-stage planet gear combined type six-gear automatic transmission. The single-stage and double-stage planet gear combined type six-gear automatic transmission comprises a front-row single-stage planet gear mechanism composed of a front-row planet carrier (6), a front-row planet gear (7), a front-row sun gear and a front-row gear ring, a middle-row double-stage planet gear mechanism composed of a middle-row planet carrier (13), a middle-row first planet gear (11), a middle-row second planet gear (10), a middle-row sun gear and a middle-row gear ring, and a rear-row single-stage planet gear mechanism composed of a rear-row planet carrier (15), a rear-row planet gear (17), a rear-row sun gear (16) and a rear-row gear ring (18). The automatic transmission has the beneficial effects of being simple and compact in structure, few in machining part type, low in cost, few in executing component, little in executing component transformation during gear shifting and not prone to movement interference.
