Embodiment 1

[0036] like Figure 3 to Figure 4 As shown, the continuously variable transmission mechanism of the relay transmission of the variable diameter gear includes three parts: the transmission toothed belt group 2, two relay transmission gears 1 and two variable diameter adjustment mechanisms 3, wherein the power input shaft 4 is connected to a variable diameter adjustment mechanism 3. The diameter adjustment mechanism is connected, and the power output shaft 5 is connected with another diameter reduction adjustment mechanism to realize the transmission of stepless speed change. The specific structure of each part is as follows:

[0037] There are two relay transmission gears in a pair, one is the driving wheel and the other is the driven wheel, which are connected and driven by the transmission toothed belt group. The reduction adjustment of the transmission gear can change the transmission ratio between the driving and driven wheels. Its specific structure includes a variable-d...

Abstract

The invention discloses a variable-speed transmission mechanism for relay transmission of variable-diameter gears. The variable-speed transmission mechanism comprises two variable-diameter relay transmission gears, variable-diameter adjusting mechanisms, a power input shaft and a power output shaft, wherein the two variable-diameter relay transmission gears are connected with each other through a transmission gear group; the variable-diameter adjusting mechanisms are respectively arranged on the two variable-diameter relay transmission gears; the power input shaft is connected with one variable-diameter adjusting mechanism, and the power output shaft is connected with the other variable-diameter adjusting mechanism. Based on the basic principle of infinitely variable speed, through unique and novel design concept, variable transmission ratio of a main driven wheel is realized by utilizing a clack body combined type variable-diameter wheel body, effective variable-diameter control is realized through the variable-diameter adjusting mechanisms, and power transmission is realized through engagement of gear belts and gears; the variable-speed transmission mechanism is simpler in structure, superior in weight volume and lower in production and manufacturing costs; moreover, the variable-speed transmission mechanism is firmer in structure, the bearing load and torque transmission capacity are greatly improved, and the problems in the prior art that thermal decay exists and larger torques cannot be transmitted through friction transmission speed are solved, so that the variable-speed transmission mechanism can be widely applied to large-displacement automobiles.

Description

technical field [0001] The invention relates to the technical field of continuously variable transmission (CVT), in particular to a continuously variable speed transmission mechanism of variable diameter gear relay transmission. Background technique [0002] A continuously variable transmission is a transmission whose transmission ratio can be continuously changed within a certain range, referred to as CVT (abbreviation of Continuously Variable Transmission in English). It uses the transmission belt and the driving and driven wheels with variable working diameter to transmit power, and can realize the continuous change of the transmission ratio, so as to obtain the best match between the transmission system and the engine working conditions, maximize the use of the characteristics of the engine, and improve the performance of the vehicle. The power and fuel economy are more and more used in automobiles. [0003] A core problem of continuously variable transmission is how to...
