Abstract
The invention discloses a shift lever assembly of the two-gear transmission assembly of electric vehicle. A first steel ball locating groove, a second steel ball locating groove and a third steel ball locating groove are formed in the front side of the left end of a shift lever from left to right side by side. The structure of the first steel ball locating groove and the structure of the third steel ball locating groove are identical. The long edge of the first steel ball locating groove is in the radial direction of the shift lever. A first groove is formed in the center of the first steel ball locating groove. The long edge of the second steel ball locating groove is in the radial direction of the shift lever. A second groove is formed in the center of the second steel ball locating groove. A gear shifting groove is formed in the top of the right end of the shift lever. The right end face of the fork-shaped portion of a gear shifting fork is provided with three locating planes. The sleeve-shaped portion of the front side of the gear shifting fork is arranged on the right portion of the gear shifting rod in a sleeved mode. An elastic cylindrical pin is inserted into a pass hole in the gear shifting fork and a pass hole in the shift lever at the same time. The shift lever assembly can slide under the shifting of a gear shifting rocker arm assembly, and then gear shifting is conducted; during gear shifting, locating can be achieved through locating steel balls in the locating steel ball grooves; besides, the gear shifting fork and the shift lever are fixed firmly.
