Double star hydraulic continuously variable transmission

Abstract

The invention relates to a double-star hydraulic continuously variable transmission. The double-star hydraulic continuously variable transmission includes two transmission shafts arranged in parallel. A transmission cylinder is coaxially sleeved on the outside of each transmission shaft. The two transmission shafts The outer cylinder wall of the cylinder is cut outwards and frictionally contacted; a pair of electrode plates are arranged parallel to the upper and lower cylinder ends of the transmission cylinder, and the electrode plates are in sealing contact with the cylinder end of the transmission cylinder. The formed airtight cylindrical space is filled with electrorheological fluid; a guide tube is installed through the electrode plate, one end of the guide tube is connected to the controller, and the other end is connected with the airtight cylindrical space; The outer circumference of the transmission cylinder is evenly distributed with limiting columns, the limiting columns include a body and a telescopic base; the telescopic base is electrically connected to the controller; the transmission has a novel and unique structure, low manufacturing cost, and a compact structure. It has a large adjustment range and can meet wider use occasions.

Description

technical field [0001] The invention relates to a transmission, especially a continuously variable transmission. Background technique [0002] Continuously variable speed technology, using the transmission belt and the variable working diameter of the driving and driven wheels to cooperate with each other to realize the continuous change of the transmission ratio; the common transmission methods are divided into three types, liquid transmission, electric transmission and mechanical transmission; The manufacturing accuracy is too high, the price is expensive, and oil leakage is prone to occur during operation at the same time; although the electric transmission has a large adjustment range and a wide power range, it has low efficiency at low speeds and unstable operation, relatively high prices, and maintenance is also relatively difficult. It is cumbersome; the mechanical transmission method has a simple structure and is easy to maintain, but the processing and lubrication r...

[0002] Continuously variable speed technology, using the transmission belt and the variable working diameter of the driving and driven wheels to cooperate with each other to realize the continuous change of the transmission ratio; the common transmission methods are divided into three types, liquid transmission, electric transmission and mechanical transmission; The manufacturing accuracy is too high, the price is expensive, and oil leakage is prone to occur during operation at the same time; although the electric transmission has a large adjustment range and a wide power range, it has low efficiency at low speeds and unstable operation, relatively high prices, and maintenance is also relatively difficult. It is cumbersome; the mechanical transmission method has a simple structure and is easy to maintain, but the processing and lubrication requirements of the parts are relatively high, and the load-carrying capacity is low; therefore, the traditional continuously variable transmission methods have shortcomings and cannot be applied to more comprehensive occasions ; At the same time, the high price is not conducive to the promotion and use of continuously variable transmissions
