Description

technical field

[0001] The invention relates to the technical field of automobile transmissions, in particular to a double-input-shaft five-speed-ratio transmission mechanism. Background technique

[0002] In some applications, the transmission system is required to have multiple speed ratios to expand the output speed and torque range to meet application requirements, such as vehicles with complex and changeable driving conditions, which require a wide range of speed and torque to meet starting, acceleration, climbing, high-speed Driving and other driving conditions, different working conditions have huge differences in speed and torque requirements, and automobile engines, especially gasoline engines and diesel engines widely used as automobile engines, provide a limited range of speed and torque, especially for high-efficiency speed and torque. The torque range is smaller, and the automobile transmission is required to provide multiple speed ratios to adjust the contradic...
