Embodiment 1

[0039] see figure 1 and figure 2 , the present embodiment discloses a single pair of gear continuously variable transmission device, including an external meshing driving wheel and a driven wheel. The driving wheel and the driven wheel have the same structure. Both the driving wheel and the driven wheel include gear teeth 6 and a base.

[0040] see Figure 8 and Figure 9 , the gear tooth 6 includes a gear tooth body 601 and a connecting block 602 . The connection block 602 is a rectangular parallelepiped as a whole. The four side walls of this cuboid are successively marked as a first side wall, a second side wall, a third side wall and a fourth side wall. The connecting block 602 is provided with a positioning hole 6021 passing through the upper and lower surfaces of the connecting block 602 . The gear tooth body 601 is disposed on the first side wall. A straight spring piece 603 is arranged on the third side wall. The straight spring piece 603 is provided with a wir...

Abstract

The invention provides a stepless speed change device for a single pair of gears. The stepless speed change device comprises a drive gear and a driven gear. Teeth of the drive gear mesh with teeth ofthe driven gear, the radius or the tooth number of the drive gear and the driven gear can be continuously changed according to the requirements of a transmission device ECU, and then stepless speed change is achieved. According to the stepless speed change device, stepless speed change is achieved while the transmission efficiency is improved.

Description

technical field [0001] The invention relates to the field of vehicle transmissions, in particular to a single-pair gear continuously variable transmission device. Background technique [0002] At present, transmissions are mainly divided into manual transmissions and automatic transmissions. The manual transmission is composed of many pairs of gears, and its efficiency is high, but it cannot realize stepless speed change, and its comfort is poor. There are many types of automatic transmissions, mainly hydraulic automatic transmissions (AT), electromechanical automatic transmissions (AMT), continuously variable automatic transmissions (CVT) and dual clutch transmissions (DCT). Although the automatic transmission is good in comfort, its efficiency is not as high as that of the manual transmission, and its structure is complicated. [0003] Therefore, it is urgent to develop a continuously variable transmission device with simple structure and high efficiency. Contents of t...
