Abstract

The invention discloses a variable transmission mechanism of electric motorcycles. The variable transmission mechanism comprises a driving belt pulley set, a driven belt pulley set, a transmission belt and an oil pressure device. The driving belt pulley set moves in the axial direction of the input shaft so as to adjust the first pitch circle radius. The driven belt wheel set moves in the axial direction of the output shaft so as to adjust the second pitch circle radius. The transmission belt is connected with the driving pulley set and the driven pulley set. The oil pressure device comprises a driving end cylinder body arranged on the driving belt pulley set and a driven end cylinder body arranged on the driven belt pulley set, the driving end cylinder body and the driven end cylinder body are communicated through a pressure groove, and pressure in the groove provides thrust for the driving belt pulley and the driven belt pulley so as to keep clamping force on the transmission belt.

Description

technical field [0001] The invention relates to the field of speed change mechanisms of electric locomotives, in particular to a speed change mechanism of electric locomotives which prevents transmission belts from slipping through an oil pressure device. Background technique [0002] On a locomotive that traditionally uses a fuel engine, a continuously variable transmission (Continuously Variable Transmission, CVT) is installed to drive the locomotive. Such as figure 1 As shown, the transmission device includes a drive pulley set 10 , a driven pulley set 11 and a drive belt 12 . The drive pulley set 10 is connected to the fuel engine 13 and rotates as the fuel engine 13 runs. When the drive pulley set 10 rotates, as the speed increases, the centrifugal force of the centrifugal roller 14 also increases and pushes the movable drive pulley to produce axial displacement, thereby changing the position of the drive belt 12 in the drive pulley set 10 (pitch circle diameter chan...
