Abstract

A conical column constantly variable transmission comprises a transmission shell, an input shaft, an output shaft, a gear shifting push pump, a conical column a, a conical column b, a push rod, a pushplate, a driving belt, a sliding sheet gear a and a sliding sheet gear b. The input shaft is installed at one end of the transmission shell in a rotating mode, and the output shaft is installed at the other end of the transmission shell in a rotating mode. The conical column a is fixedly installed on the input shaft, and the conical column b is fixedly installed on the output shaft. The sliding sheet gear a is installed on the conical column a, and the sliding sheet gear b is installed on the conical column b. The driving belt sleeves the sliding sheet gear a and the sliding sheet gear b. Thegear shifting push pump drives the push rod to move leftwards and rightwards, the push rod can drive the push plate to move leftwards and rightwards, the push plate pushes the driving belt to move, the driving belt drives the sliding sheet gear a and the sliding sheet gear b to move on the conical column a and the conical column b, the diameters of the sliding sheet gear a and the sliding sheet gear b can be continuously changed, and therefore the variable speed ratio transmitted by the input shaft to the output shaft can be continuously changed.

Description

technical field [0001] The invention relates to the field of continuously variable transmissions, in particular to a cone-column continuously variable transmission. Background technique [0002] Continuously variable transmission, which uses the drive belt and the variable working diameter of the main and driven wheels to transmit power, can realize the continuous change of the transmission ratio, so as to obtain the best match between the transmission system and the engine working conditions. [0003] The existing continuously variable transmission comprises two pulleys and a metal belt, and the metal belt is sleeved on the two pulleys. The pulley is composed of two discs. The grooves in the middle of the two discs form a V shape. One of the discs is operated by a hydraulic control mechanism, which can be separated and drawn according to different engine speeds. The V-shaped concave The slot widens or narrows accordingly, raising or lowering the metal belt, thus changing t...
