一种单双级行星齿轮组合式七挡自动变速器
摘要：
本发明公开了一种单双级行星齿轮组合式七挡自动变速器，包括由前排齿圈、前排太阳轮、前排行星架、前排第一行星齿轮和前排第二行星齿轮构成的前排双级行星齿轮机构；由中排齿圈、中排太阳轮、中排行星架、中排第一行星齿轮和中排第二行星齿轮构成的中排双级行星齿轮机构；由后排齿圈、后排太阳轮、后排行星架和后排行星齿轮构成的后排单级行星齿轮机构；其中，所述前排太阳轮和中排太阳轮制成共用的前中排太阳轮，所述前排行星架和中排行星架制成共用的前中排行星架。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。
摘要（英）：

The invention discloses a single-stage planetary gear and two-stage planetary gear combined seven-gear automatic transmission. The single-stage planetary gear and two-stage planetary gear combined seven-gear automatic transmission comprises a front-row two-stage planetary gear mechanism, a middle-row two-stage planetary gear mechanism and a rear-row single-stage planetary gear mechanism. The front-row two-stage planetary gear mechanism is composed of a front-row gear ring, a front-row sun gear, a front-row planetary rack, a first front-row planetary gear and a second front-row planetary gear. The middle-row two-stage planetary gear mechanism is composed of a middle-row gear ring, a middle-row sun gear, a middle-row planetary rack, a first middle-row planetary gear and a second middle-row planetary gear. The rear-row two-stage planetary gear mechanism is composed of a rear-row gear ring, a rear-row sun gear, a rear-row planetary rack and a rear-row planetary gear. The front-row sun gear and the middle-row sun gear are made into a shared front and middle-row sun gear. The front-row planetary rack and the middle-row planetary rack are made into a shared front and middle-row planetary rack. The automatic transmission has the advantages that the structure is simple and compact, a few types of machined parts exist, cost is low, the number of executive components is small, the executive components change slightly during gear shifting, and motion interference is not likely to occur.
