Abstract
A pneumatically automatic gearshift executer for the second gear of an electric bus is disclosed, wherein a gearshift for the first gear, the neutral position and the second gear is realized by the combined control of three solenoid valves. Additionally, a clutch is integrated to control the solenoid valves, so that the pneumatically automatic gearshift executer for the second gear of an electric bus is compact in structure and reliable in performance. A permanent magnet is combined on a gearshift shifting head and used together with a gearshift sensor, so that the position of the gearshift shifting head can be accurately measured. A dustproof seat is installed at one side of a gearshift shaft, so that the entrance in a gearbox of dust and water can be avoided.
