Embodiment 1

[0054] Example 1: Combining figure 1, the three (or appropriate number) connecting rods [2] of the crankshaft [1] are all installed (with a certain initial pressure or energy) compression springs (or compressible airtight air chambers) [3], and mutually form 120 degree angle (or equal angle), one end of the spring [3] is installed or tightly pressed on the shaft sleeve [12] of the connecting rod [2], and the other end is installed (or sleeved) on the bottom of the toothed spring seat [5] , the connecting rod [2] is movably connected with the toothed spring seat [5], and controls the movable range of the toothed spring seat [5] through the positioning (or braking) device [6] on the connecting rod [2], one-way The outer ring of the clutch (or locking mechanism) [4] processes the gear and meshes with the toothed spring seat [5], and the inner ring and the output shaft [7] are fixedly installed by splines or pin holes. In the process of torque transmission (or speed control), whe...

Embodiment 2

[0059] Example 2: Combining Figure 8 , Figure 9 , Figure 10 , it is three (or a suitable number) such as Figure 10 One end of shown elastic lever [86] is movably installed on crankshaft [1] through axle sleeve [90], and axle sleeve [90] space is advisable with longer so that crankshaft [1] can slide up and down in axle sleeve when rotating, The other end pin hole [91] is flexibly connected with the rack [83]; the support [87] is installed in the middle part of the elastic lever [86], and the support [87] can adopt Figure 9 Shown supporting structure, it is to install bearing [85] on the both sides of elastic lever [86] swing force, and bearing [85] warp shaft [89] is installed on the support [88], makes elastic lever [86] rotate It can move up and down during the torque transmission process; guide rails [84] are installed on both sides of the rack [83] so that the rack [83] can slide left and right on the guide rails [84], and the toothed outer ring of the one-way clut...

Embodiment 3

[0060] Example 3: Binding Figure 14 , it is that toothed connecting rod [2] is movably installed on the crankshaft [1] through the shaft sleeve [12], the transmission disc [35] is fixedly installed on the output shaft [7], the transmission disc [33] is installed movably, the transmission wheel [34], the transmission disc [33] is used as the outer ring (or inner ring) of the one-way clutch [4], and the transmission wheel [34] is used as the inner ring (or outer ring) of the one-way clutch [4] and is connected with the connecting rod The racks of [2] are meshed, and the two ends of the coil spring [13] are fixedly mounted on the transmission disc [35] and the transmission wheel disc [33] respectively, (the coil spring [13] can use one set or two sets and more than components). During the torque transmission process, the rotation of the crankshaft [1] causes the torque to be transmitted to the output shaft [7] by the toothed connecting rod [2] through the one-way clutch [4] to ...

Abstract

The invention discloses a stroke-variable elastic continuously-variable transmission or rotary speed controller which is a transmission mechanism with elastic elements or components in proper number as torque. During torque transmission, the elastic elements or components automatically adjust stroke to change transmission ratio by different degrees of elastic deformation according to change of work states and control requirements, and an auxiliary device is added into the elastic elements or components to change initial pressure (or energy) or elasticity coefficient of the elastic elements or components, or to adjust time ratio of energy accumulation and release (namely locking duty ratio) or adjust the number of the elastic elements or components involved in torque transmission, or adjust transmission ratio of input or output shafts in order to enhance stroke adjustment capability of the elastic elements or components during torque transmission, so that the transmission can acquire larger variable-speed, variable-torque or rotary speed control range and can complete continuously-variable transmission (or rotary speed control) tasks within a certain range. The stroke-variable elastic continuously-variable transmission or rotary speed controller is high in transmission efficiency, convenient to control and easy to produce.

Description

technical field [0001] The invention relates to a transmission, in particular to a transmission that utilizes elastic elements or components to adjust the overall stroke according to changes in working conditions and control requirements to realize stepless changes in torque and rotational speed, or to realize the control of a certain controlled rotating component. The speed is steplessly controlled. technical background [0002] Realizing continuously variable transmission is the goal that the automobile industry and many other industries have been longing for. The current hydraulic automatic transmission and electronically controlled continuously variable transmission have made great progress to a certain extent, but due to: 1. The transmission ratio of hydraulic automatic transmission is not Continuous, and the transmission efficiency is low, and the power performance and fuel economy are not ideal. 2. Electronically controlled continuously variable transmissions can onl...
