Abstract

The invention discloses an automatic transmission which comprises a transmission switching system and a gear transmission system, and a reverse action device is matched with a one-way conical surface clutch to achieve gear shifting. The automatic transmission is characterized in that the reverse action device comprises an assembly of a spring seat of a driven frame and an outer conical surface ring and an assembly of a spring seat of a driving frame and a sliding sleeve seat, and the transmission switching system further comprises a manual hydraulic reverse gear. The spring seat is a single-group spring seat or a double-group spring seat; the single-group spring seat is assembled with the sliding sleeve seat or the outer conical surface ring through a buckle or a pressing plate and then is welded with the pressing plate. And the double-group spring seat is assembled with the sliding sleeve seat or the outer conical surface ring through a buckle or a pressing plate and then is welded with the pressing plate. The lever or the driving lever of the manual hydraulic reverse gear is also matched with a reversing microswitch and a forward microswitch of an electric vehicle. When the automatic transmission is assembled on the electric vehicle, the gradeability can be enhanced, and the endurance mileage can be increased.

Description

technical field [0001] The invention relates to an automatic gear shifting device of an electric vehicle drive system, in particular to an automatic gear transmission assembled on the rear axle of an electric vehicle, which can also be applied to the middle drive of a two-wheel vehicle, and belongs to the technical field of mechanical transmission. Background technique [0002] At present, electric vehicles on the market are generally not equipped with automatic transmissions, which have small torque and high current. Whether it is climbing, speeding up, or carrying a load, it must be realized by doubling the current, especially in mountainous and hilly areas where frequent climbing is required. Slope, consumes a lot of power, greatly reducing the mileage of the continuation. The service life of the battery is short, and it is easy to burn out the motor and controller. The existing manual shifting is also very inconvenient. It is necessary to park the vehicle before operati...
