Title:
ELECTRIC VEHICLE VARIABLE SPEED DRIVE SYSTEM WITH AUTOMATIC FEEDBACK SPEED REGULATION FUNCTION
Document Type and Number:
WIPO Patent Application WO/2021/248514
Kind Code:
A1
Abstract:
An electric vehicle variable speed drive system with an automatic feedback speed regulation function, the system comprising an input shaft (10), a connecting shaft (11) and an output shaft (12), wherein the input shaft (10), the connecting shaft (11) and the output shaft (12) are arranged in parallel; the input shaft (10) is connected to the connecting shaft (11) in a meshing manner by means of two input gears (13) meshing with each other; the connecting shaft (11) is provided with several gear-position fixed gears (14) which are sequentially arranged in the axial direction of the connecting shaft (11); each of the gear-position fixed gears (14) is connected to a gear-position movable gear (15) in a meshing manner; each gear-position movable gear (15) is rotatably connected to the output shaft (12); each gear-position movable gear (15) corresponds to one gear-position connecting mechanism (16) which is arranged on the output shaft (12); each gear-position connecting mechanism (16) is connected to the corresponding gear-position movable gear (15) so as to drive the output shaft (12) to rotate; each gear-position connecting mechanism (16) is connected to a gear-position adjusting mechanism (17); the gear-position connecting mechanism (16) is driven by the gear-position adjusting mechanism (17) so as to be connected to or disconnected from the corresponding gear-position movable gear (15); and the gear-position adjusting mechanism (17) comprises a push rod (18) connected to the corresponding gear-position connecting mechanism (16).
