IDLING TAP PREVENTING DEVICE FOR TRANSMISSION

PURPOSE:To prevent a gear tap from being generated in the time of idling, by constituting a device such that one end of an oil receiver cylinder presses a countershaft in the axial direction or releases it from being pressed in accordance with the pressing force of spring and the vertical movement of a float. CONSTITUTION:In the time of idling, a counter gear 21, as it rotates, scrapes oil, and its level is placed in a position 10a. Here a float 7 moves upward, and as the float moves an oil receiver inner cylinder 4 moves leftward by pressing force of a spring 5. And the inner cylinder 4, whose lip 9 comes into contact with a countershaft end face 1, stops by pressing it. Accordingly, rotating resistance is always given to a countershaft 19, and a gear meshing tap is prevented by suppressing the gear 21 from floating in the rotary direction by the amount of backlash. While in the time of running, the oil level is placed in a position 10b because a rotary speed of the gear 21 increases, and a loss of driving power is prevented by moving the float 7 downward while the inner cylinder 4 rightward so as to eliminate the contact of the lip 9 with the end face 1.
