Abstract

The invention provides an infinitely variable speed transmission mechanism, and relates to the technical field of transmission mechanisms. The infinitely variable speed transmission mechanism comprises a transmission mechanism, wherein a threaded rod is arranged in the middle in the transmission mechanism; the front side and the rear side of the threaded rod are independently provided with a sliding chute; the middle of the outer part of the threaded rod is covered with a round pipe; the front side and the rear side of the inner wall of the round pipe are independently rotatably connected witha plurality of balls; the balls and the sliding chutes are in sliding connection; the left end and the right end of the threaded rod are independently in threaded connection with a thread ring; one side of each thread ring is independently welded with a shifting fork; two shifting forks have opposite orientations; the right side of the threaded rod is fixedly provided with a stopping block; and the left side of the threaded rod is fixedly connected with an air cylinder. The infinitely variable speed transmission mechanism has the beneficial effects that under mutual cooperation of the shifting forks, the thread rings and the threaded rod, transmission wheels can be driven to move between left and right, and a rotation wheel diameter of a variable speed belt is changed so as to achieve a purpose of speed regulation. The infinitely variable speed transmission mechanism has a simple structure, is stable in axial straight-line speed change in short distance and small space, is quick in improving speed and is simple to operate.

Description

technical field [0001] The invention relates to the technical field of transmission mechanisms, in particular to a continuously variable transmission mechanism. Background technique [0002] Continuously variable transmission is a type of automatic transmission, which refers to a transmission system that can continuously obtain any transmission ratio within the transmission range. The best match between the drive train and the engine operating conditions can be obtained through continuously variable transmission. Common CVTs include hydromechanical CVT, metal belt CVT and variable slope CVT. The existing continuously variable transmission mechanism has complex structure, high production cost, troublesome speed regulation, and slow speed increase. Contents of the invention [0003] The invention provides a continuously variable speed transmission mechanism, which can drive the transmission wheel to move left and right under the mutual cooperation of the shift fork, the th...
