Double-ring stepless speed changer

Abstract

The invention relates to a double-ring stepless speed changer, which comprises a casing, a driving shaft and a transmission shaft, wherein the driving shaft and the transmission shaft are in parallelarrangement; a driving ring is coaxially arranged outside the driving shaft; the driving ring and the driving shaft are connected through a telescopic rod structure; a transmission ring is coaxially arranged outside the transmission shaft; the transmission ring and the transmission shaft are connected through the telescopic rod structure; the driving ring and the transmission ring maintain the exterior contact and friction contact; each of the driving ring and the transmission ring comprises a ring bone and a ring sleeve made of elastic materials; the ring bone comprises a tightly winding mainspring ring; all layers of the mainspring ring are tightly attached and can relatively slide; the telescopic rod structure arranged in the peripheral direction of the driving shaft and the transmission shaft is electrically connected with a controller. The double-ring stepless speed changer has various advantages that the structure is novel; the repair is convenient; the occupied space is small; the installation and the use are convenient, and the like. The technical defects of the stepless speed change in the prior art can be effectively overcome.

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. cumbersome; the mechanical transmission method is simple in structure, convenient and cheap in maintenance, but the processing and lubric...
