Problems solved by technology

Energy loss at high torques due to the smooth surface of the conical wheel
The hydraulic system and the cone wheel that change the transmission ratio require extra energy to work, which will cause unnecessary energy loss to the engine or electric motor
Drive belts, steel belts, and chains are prone to breakage at high torque, or the cone wheel is strained

Abstract

A hydraulic stepless transmission comprises a transmission shell, a transmission ratio regulation slide block, a liquid medium filling hole, a driving blade, a gear shifting regulation rod, a drivingwheel set, a driven wheel set and a driven blade, wherein the gear shifting regulation rod which can slide horizontally is installed on the left side inside the transmission shell, the transmission ratio regulation slide block can slide horizontally under driving of the gear shifting regulation rod, volume-adjustable sealed cavities can be formed between two ends of the transmission ratio regulation slide block and the driving wheel set and the driven wheel set, and the space is full of a liquid medium; among an upper sealed cavity and a lower sealed cavity formed by the transmission ratio regulation slide block and the driving wheel set and an upper sealed cavity and a lower sealed cavity formed between the transmission ratio regulation slide block and the driven wheel set, the upper cavities are driven low-pressure cavities and the lower cavities are driven high-pressure cavities; and with pipelines, the driving high-pressure cavity communicates with the driven low-pressure cavity, and the driven high-pressure cavity communicates with the driving low-pressure cavity. The hydraulic stepless transmission provided by the invention has the advantages of action reliability, good operability, high gear ratio and high torque.

Description

technical field [0001] The invention relates to the field of transmission structure, in particular to a hydraulic continuously variable transmission. Background technique [0002] The CVT of the prior art changes the transmission ratio by controlling the closure and expansion of the conical wheel by a hydraulic pump to change the radius of gyration of the wheel body, and uses belts, steel belts, and chains for transmission. Due to the smooth surface of the conical wheel, energy is lost under high torque conditions. The hydraulic system and the cone wheel that change the transmission ratio require extra energy to work, which will cause unnecessary energy loss to the engine or electric motor. Drive belts, steel belts, and chains are prone to breakage or conical pulley strain when the torque is high. Contents of the invention [0003] The purpose of the present invention is to replace conical wheels, belts, steel belts, chains and other transmission components, reduce energ...
