Automatic transmission capable of transmitting power by aid of shaft and plungers

Abstract

The invention relates to the field of electronic-control automatic transmissions for vehicles, in particular to an automatic transmission capable of transmitting power by the aid of a shaft and plungers. The automatic transmission is characterized in that semicircular pits are uniformly machined on the radius circumferential surface of the shaft and are matched with the plungers corresponding to the semicircular pits, and the plungers are integrally connected with the shaft under the action of external pressure, so that the power can be transmitted. The automatic transmission with the structure has the advantages that the automatic transmission is simple in structure as compared with the traditional gear transmission, automatic gear shifting can be implemented without cutting off the power, the driving smoothness and the dynamic performance of a vehicle are improved, the economical efficiency is enhanced, and the automatic transmission not only can be used in limousines and light vehicles, but also can be conveniently popularized in trucks and heavy vehicles.

Description

technical field [0001] The invention relates to the field of electronically controlled automatic transmissions for vehicles, in particular to an automatic transmission that transmits power through shafts and plungers. Background technique [0002] Vehicle automatic transmissions have been widely used in cars so far, and have been favored by the majority of users as the first choice for car purchases. Due to the complex production process and high cost of automatic transmissions equipped on vehicles in our country, most of the automatic transmissions used and produced in China are 4-5 speed automatic transmissions, and low-end cars are basically not equipped for installation. Automatic transmissions above 5 speeds are all used in high-end luxury cars. This restricts the demand and use of automatic transmissions by the majority of users, and the invisible price barrier keeps them out. At the same time, due to the structure and price factors, the global automatic transmission...
