Abstract

The invention relates to a gear shifting mechanism suitable for an automobile two-gear gearbox, and belongs to the technical field of gearbox gear shifting. A gear shifting motor is fixedly arranged in the gearbox, a coaxial worm is fixed to an output shaft of the gear shifting motor, the horizontal worm is meshed with a horizontal fan-shaped turbine on one side, a gear shaft is fixedly connected to the rotating center of the fan-shaped turbine, and the upper end of the gear shaft is rotationally connected with a gear shifting cover plate through a bearing. The upper end of the gear shaft is connected with an angle sensor on the upper end face of the gear shifting cover plate, a gear shifting boss is fixedly arranged on the side, away from the worm, of the fan-shaped turbine, a shifting fork shaft is arranged below the gear shifting boss, a gear shifting fork is connected to the shifting fork shaft in a sliding mode, and two check blocks are arranged on the upper end face of the gear shifting fork at intervals. The gear shifting boss is arranged between the two check blocks. The problem that at present, a domestic two-gear gearbox is immature in structure is solved.

Description

technical field [0001] The invention belongs to the technical field of gearbox shifting, and in particular relates to a shifting mechanism suitable for a two-speed gearbox of an automobile. Background technique [0002] The main components of the powertrain of a new energy electric vehicle are the motor and the gearbox. At present, the motor market is flourishing, and some technical routes have been formed. In terms of gearboxes, most of the models already on the market use single-stage gearboxes. The advantages of single-stage gearboxes are that there are not too many components, quality is easy to guarantee, cost is low, and reliability is high. The disadvantage is that the motor cannot work in the optimal efficiency zone, which also limits the maximum speed and maximum gradeability. If a low-cost low-speed motor is used, the maximum speed of an electric vehicle with a single-stage reduction box is generally 80Km / h ~ 100Km / h, and the grade is generally about 20%. If you...
