Away from setting double wedge, double wedge and chain are flexibly connected, and cone pulley is rotated with transmission shaft, drive half double wedge connecting rod by double wedge by chain
Self-locking nut slides up and down in groove.
The depth of groove of the stepless automatic transmission is parallel with the conical surface.
Upper end is placed equidistant with more than one double wedge in the middle part of half double wedge connecting rod of the stepless automatic transmission, and both ends are spiral shell
Line.
The cone pulley of the stepless automatic transmission is that thickness periphery in middle part is thin, and groove is set as three or more.
The self-locking nut of the stepless automatic transmission is cut from outside to inside slots together, is round spiral shell inside self-locking nut
The threaded connection of silk and half double wedge connecting rod two end, outside are semicircle, ellipse, half cone-shaped, trapezoidal or diamond shape.
The end B that the cabinet left front end of the stepless automatic transmission stretches out transmission shaft is input terminal, and cabinet right rear end stretches out
The C-terminal of transmission shaft is output end, and the input end B and output C-terminal are convertible.
The beneficial effects of the utility model are: due to using half double wedge connecting rod and self-locking nut activity sliding setting cone
In the groove of wheel, change the size of transmission ratio using chain drive, speed ratio value is big, and power transmitting is non-slip, can also arbitrarily take
With speed ratio, overload large torque transmission can be born.And it is small in size, structure is simple, and light-weight, manufacturing process is simple, installation and maintenance side
Just, oil consumption is low, and production cost is low, greatly reduces manufacture and maintenance cost, can realize with electronic product control system more intelligent
Combination, be the development trend of the following automatic gear-box.
