Embodiment Construction
[0011] The present invention is described in further detail below:
[0012] The present invention relates to a ten-speed transmission with fixed shaft and planetary compound transmission. The transmission is a ten-front three-reversed transmission, which is composed of a fixed shaft transmission part and a planetary transmission part, including an input shaft, an intermediate shaft, a coupling shaft and an output shaft. , Seven pairs of meshing fixed shaft gears, eight operating members (can be four double-sided synchronizers) and a compound planetary row.
[0013] The engine power is transmitted from the input shaft to the intermediate shaft, and the fixed shaft gear on the intermediate shaft divides the power and transmits it to the composite planetary row through the coupling shaft (connection I shaft, connection II shaft and connection III shaft), and the planetary row concatenates the power from The planetary carrier output controls two operating parts at the same time, a...

The invention discloses a ten-gear transmission with the dead axle and planet composite transmission function. The ten-gear transmission with the dead axle and planet composite transmission function is composed of a dead axle transmission portion and a planetary transmission portion, and comprises an input shaft, an intermediate shaft, a coupling shaft, an output shaft, seven pairs of normally-meshed dead axle gears, eight control parts, namely four double-sided synchronizers, and a composite planetary row. Power of an engine is transmitted to the intermediate shaft from the input shaft, the power is divided by the dead axle gears on the intermediate shaft, then the power is transmitted to the composite planetary row through the coupling shaft, junction is carried out on the power through the composite planetary row, the power is output through a planet carrier, the two control parts are controlled at the same time, and ten forward gears including two overdrive gears, and three reverse gears can be achieved. According to the ten-gear transmission with the dead axle and planet composite transmission function, due to the fact that the dead axle and planet composite transmission mode is adopted, a plurality of gears are achieved through a compact structure, gear shifting impact of vehicles can be reduced, and gear shifting quality is improved.
Description
technical field [0001] The invention belongs to the technical field of mechanical transmission, and relates to a transmission, in particular to a ten-speed transmission with fixed shaft and planetary compound transmission. Background technique [0002] With the development of control technology, automatic transmissions have tended to be popularized. Regardless of the fact that there are too many gears and the driver is tired of changing gears frequently, increasing the number of gears in the transmission or adopting a continuously variable transmission can effectively improve the shifting speed of the vehicle. gear quality and ride comfort. CVTs are generally used in low-emission, low-power vehicles due to their limited carrying capacity, which has certain limitations. Mechanical stepped transmissions are widely used in vehicle transmission due to their high transmission efficiency. At present, the number of gears is mostly designed as five, six or even eight gears. [000...
