Abstract

PURPOSE:To enable to establish selectively a speed change ratio of a back gear at a value larger sufficiently than a normal one, by a method wherein an auxiliary input shaft is provided concentrically on an input shaft to be driven by an engine through a reduction clutch, and a counter shaft is provided in parallel with the auxiliary input shaft. CONSTITUTION:A gear 7 is fixed to an input shaft 6 to be connected with a crank shaft 4 through a clutch 5 and an auxiliary input shaft 9 is provided beyond the gear 7 through a reduction clutch 8. The auxiliary input shaft 9 side of the clutch 8 supports a gear 11 rotatably to the same shaft 9 and the clutch 8 is connected with either of gears 11, 7 selectively. Gears 12-15 whose numbers of cogs are different to each other are fixed to the auxiliary input shaft 9, which are meshed with gears 17-19 supported by a countershaft 16 supported close to the auxiliary input shaft 9 appropriately. The titled device is enabled to obtain a far larger speed reduction ratio as compared with the ratio obtainable at the time of connection with a gear 7 side, when a back gear 21 is made selectively connectable on the countershaft 16 by providing a low speed clutch 20 and the clutch 8 is connected with a gear 11 side.

The gears 17, 18, 19 on the counter shaft 16 and the reverse gear 21 operate in the same manner as in the conventional case, and the rotation of the input shaft 6 is changed into four forward speeds and one reverse speed.

されることになる。When the reduction clutch 8 connects the auxiliary input shaft 9 to the gear 11 side, the rotation of the input shaft 6 is controlled by the gears 7 and 22.
, gear 23, gear 11, rig/clutch 8, and auxiliary input shaft 9 in this order. After this, the gears 12, 13, 14.15 on the sub input shaft 9, the gears 17, 18, 19 on the counter shaft 16, and the gear 2 for reverse
1, the human power shaft rotates 60 times and is shifted in four forward speeds and one reverse speed.

装置を、小型に構成できることになる。As shown in the above table, in the structure shown in FIG. 1, the ratio □ of the first speed does not change in both the H range and the L range. Therefore, when the reduction clutch 8 is connected to the gear 11 side, the low-speed clutch 20 on the main gear ratio side has a structure (not shown) that does not connect with the gear 22, so that in the H range, the forward speed is 4
This means that a transmission with three forward speeds and one reverse speed in the L range can be configured in a compact size.

Although the reduction ratio is larger than the speed, when escaping from a rough road by following its own trajectory, it can retreat at extremely low speed without slipping, which is advantageous for off-road operation.

A gear 2 integral with this gear 22a is rotatably supported on the
3 (supported by the counter shaft 16 in the one shown in FIG. 1) is meshed with the gear 11 on the sub-input shaft 9. This embodiment can also obtain the same functions and effects as those of FIG. 1.
