Abstract

The invention discloses an on-line stepless continuous speed change transmission device without vehicle stop. The on-line stepless continuous speed change transmission device is mainly composed of a box body, an input module, an intermediate module, a speed change module, an output module, and a tension spring. The input module comprises an input shaft and a supporting sleeve. The intermediate module comprises a control wheel, a bearing cover, a radial load bearing, an axial load bearing, a power cylinder, and a power disc. The speed change module comprises a shifter fork, a guide rail, a sliding block, a crank, and a shifter fork driving shaft. The output module comprises a friction wheel, a transmission cylinder, and an output shaft. The power disc and the supporting sleeve are arrangedaround the input shaft, and are connected by the tension spring extending in the axial direction. The tension spring is always in the stretched state. The structure is compact and operation is easy. On-line continuous stepless speed change of the transmission system is achieved without device stop during transmission operation of a machine, and accurate speed control is achieved.

Description

technical field [0001] The invention relates to the technical field of on-line continuous stepless speed change, in particular to a device capable of realizing the transmission function of on-line continuous stepless speed change under the condition that the transmission system does not stop. Background technique [0002] The traditional transmission system mostly uses gear transmission. When the speed needs to be changed, it is necessary to stop the car first to stop the output shaft from rotating. Through the gear box, the meshing of different gear ratios is changed, and then the transmission ratio is changed to change the speed of the output shaft. In this process, the motor needs to be started and stopped frequently, which not only consumes time, but also causes certain damage to the transmission system itself. [0003] Chinese invention patent CN88103976A discloses a double planetary stepless torque converter for power transmission. The double planetary stepless torque ...
