Title:
TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2021/062980
Kind Code:
A1
Abstract:
A transmission, used in an electric car, and a speed ratio gear case (2) and a gear selection case (3) being provided in an outer housing (1) of the transmission. No lubricating oil able to contact or splash into a friction component of a synchronizer is provided in the gear selection case (3). A fine intermediate shaft (4) penetrates a tubular coarse intermediate shaft (5), both ends of the fine intermediate shaft (4) extending out from the coarse intermediate shaft (5), and the coarse intermediate shaft (5) and the fine intermediate shaft (4) being positioned in the speed ratio gear case (2) and the gear selection case (3). The coarse intermediate shaft (5) and the fine intermediate shaft (4) positioned in the speed ratio gear case (2) are meshed with gears (27, 28) of an output shaft (26) by means of gears (6, 7) connected to each. The coarse intermediate shaft (5) and the fine intermediate shaft (4) positioned in the gear selection case (2) are each connected to gears (13, 15) and a synchronizer component, and gear selection is completed by power connection of the gears (13, 15) and the synchronizer component to a gear selection gear (14) in a gearshift rack (11) and a synchronizer component of an additional part. An advancer (12) is provided in the synchronizer, and before a gear to be meshed makes contact, the advancer (12) is used to cause the synchronizer friction part to make contact in advance and produces a frictional force, thus causing the gearshift rack (11) to be synchronized with the coarse intermediate shaft (5) and the fine intermediate shaft (4). The gearshift rack (11) is connected to an input shaft (19), and is connected to a hydraulic device (24) by means of a bearing, causing external gear selection signal power to be implemented. Thus, the frictional force of the friction component of the synchronizer is greater.
