Abstract
A transaxle and a two-speed drive module thereof. The two-speed drive module comprises an input shaft, an output shaft, and gear sets used for transmitting power between the input shaft and the output shaft. The gear sets comprise: a two-speed gear set having two groups of shift gear pairs that have different speed ratios, the shift gear pairs being capable of transmittingly connecting to or disconnecting from the input shaft so as to output the rotational speed of the input shaft at different speed ratios; a planetary gear set having an output end thereof being transmittingly connected to the output shaft; and a connecting gear set by which the two-speed gear set is transmittingly connected to the planetary gear set. The two-speed drive module can implement a reduction in the radial dimension, and can reduce the ground clearance of a transaxle.
