Abstract

The invention relates to a complete double-row same-kind center wheel row transmission including a planetary row structure, an input and output lock connection and brakes. A star connection planetaryrow structure with no less than two rows of planetary rows is adopted, one complete double-row exists, remaining single-layer star planetary rows are same-kind center wheel rows, and the planetary rowstructure has four conditions. The input and output lock connection has six kinds of characteristics. The gear positions of the transmission are controlled by all brakes, and half-linkage and the neutral position exist. By means of the transmission, the structure is simplified, the number of meshed gears is decreased, the self weight of the transmission is reduced, the loss during transmission isreduced, and meanwhile, the length of the entire planetary row structure is decreased as many as possible. An inverse transmission also belongs to the protecting scope of the transmission.

Description

technical field [0001] The invention relates to a planetary gear transmission, specifically a planetary gear transmission with a complete double-layer star planetary gear and the rest of which are star-connected planetary gears of the same type of center wheel planetary gear, and the planetary gear gears are controlled by controlling each brake. . Background technique [0002] In order to convert the torque and speed of the transmission power system, many power machines are equipped with planetary transmissions. Existing planetary transmissions shift gears by controlling clutches and braking clutches. Different planetary transmissions have their own technical characteristics in terms of their planetary structures and input-output locking connections (including the combination of clutches and braking clutches). I have invented the planetary transmission that changes gears all by controlling each brake. However, the various planetary gear transmissions mentioned above have c...
