Abstract

The invention discloses a planetary and hydraulic combined automatic continuously-variable transmission. According to the planetary and hydraulic combined automatic continuously-variable transmission, a planetary deceleration starting system, a plunger hydraulic mandatory speed control system and a centrifugal force automatic random control system are organically combined together and the rigid advantages that planetary transmission is large in gear ratio and transmission power, the flexible advantages that a plunger hydraulic system is high in overload resistance, impact resistance and infinitely variable speed performance and the advantages that a centrifugal force control device is high in randomness are fully utilized, so that the large gear ratio and high-power power automatic continuously-variable transmission which is simple, efficient and reliable is achieved.

Description

technical field [0001] The invention relates to a transmission, in particular to a planetary hydraulic resultant force stepless automatic transmission which realizes power transmission through the organic combination of planetary deceleration start, hydraulic forced transmission, and automatic random control of centrifugal force.
