Problems solved by technology

[0002] At present, continuously variable transmissions mainly adopt structures such as steel belt type and friction ring type. These structural methods all use friction transmission, resulting in relatively low torque that the existing continuously variable transmissions can withstand, and basically can only be applied to small cars and other loads. In the case of low temperature, the range of application is limited, and friction transmission can easily lead to rapid temperature rise of parts, resulting in large power loss, low transmission efficiency, and short service life of parts

Abstract

The invention discloses a continuously variable transmission mechanism, which comprises a front housing, a rear housing, a driven groove plate and a variable modulus drive device, and the driven groove plate is provided with intersecting forward grooves and reverse grooves at intervals. The variable modulus driving device includes a conical input shaft, a variable-diameter drive motor, a variable-diameter screw, a variable-diameter nut, and several sliding claws. The angles are equal, the input shaft is provided with a dovetail groove, the variable diameter nut is provided with a claw, the sliding claw is nested in the dovetail groove, and one end of the sliding claw is sleeved on the other end of the claw; And the claw drives the sliding claw to slide along the tapered end surface of the input shaft, thereby changing the modulus of the input shaft, and changing the number of engagement of the sliding claw with the forward groove and reverse groove on the driven groove plate, thereby changing the output shaft The speed can be adjusted continuously, the temperature rise is small, the power loss is small, the transmission efficiency is high, and the service life of each component is longer.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a continuously variable transmission mechanism and a transmission method. Background technique [0002] At present, continuously variable transmissions mainly adopt structures such as steel belt type and friction ring type. These structural methods use friction transmission, resulting in relatively low torque that the existing continuously variable transmissions can withstand, and basically can only be applied to small cars and other loads. In the case of low temperature, the range of application is limited, and friction transmission can easily lead to rapid temperature rise of parts, resulting in greater power loss, low transmission efficiency, and shorter service life of parts. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages mentioned above and provide a continuously variable transmission mechanism. [0004] In order...
