Definitions

  • the present invention relates to a transmission mechanism of a continuously variable transmission for heavy loads. Mouth. Background Technology
  • the present invention has low wear even under heavy loads, and has a simple operation that allows a continuous shift from a stop to a certain number of rotations, and a free shift even during a load rotation.
  • the present invention relates to a step transmission, and controls the revolving motion of a planetary gear in a planetary gear device by increasing or decreasing the oil flow resistance of a hydraulic pump that is linked to the revolution. It is a unique continuously variable transmission.
  • FIG. 1 shows an embodiment of the continuously variable transmission of the present invention.
  • FIG. 1 is a cut-away side view of the first embodiment
  • FIG. 2 is a cut-away front view taken along the line A- ⁇ of FIG.
  • FIG. 5 is a partially cutaway front view of a part of an automatic flow control mechanism of the hydraulic pump and a flow control valve.
  • FIG. 4 is a partially cutaway front view of a second embodiment of the hydraulic pump and the flow control valve.
  • a planetary gear (5) is meshed around a sun gear (2) fixed to an input shaft (1) in FIG.
  • the gear (5) meshes with a sun gear (5) fixed to the output shaft (4).
  • the planet gear (5) is supported by a shaft (6) and mounted on a holding frame (7).
  • the holding frame (7) is provided with a gear (8).
  • the gear (8) meshes with the gear (9) to move the hydraulic pump (10.
  • the hydraulic pump (10) is a gear pump.
  • the discharge amount control valve is connected to the discharge port of the hydraulic pump. (11) is installed, the valve (") is connected to the control handle 2), and all the hydraulic pumps (10) are immersed in oil. If the control handle (12) is completely closed while the input shaft ( ⁇ ) is rotating, the hydraulic pump (10 ) Does not rotate, and thus the holding frame (7) does not rotate.At this time, the rotation of the sun gear (2) is transmitted to the planetary gear (5).
  • a sheave mechanism (17) is provided on the shaft (16) of the gear (9) driven by the gear (8) of the holding frame (7), and Reciprocate the ton.
  • the two chambers (20 and 20 '>) of the cylinder (19) separated by the piston 8 are short-circuited to each other.
  • the cylinder is filled with oil.]
  • Lube (11) is installed]
  • the pulp 1) is connected to the control hand 2).
  • a plurality of such devices are provided in order to prevent pulsation, and the sives that move each of them have different rotation angles evenly.
  • the hydraulic pressure is controlled by changing the opening of the valve (11) by the control handle 2, and the rotation of the output shaft is continuously variable as in the case of the hydraulic pump. Can be. -Industrial potential
