ラム式の変速機を有する車輌のバック装置に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a backing device for a vehicle having a shift drum type transmission that changes gears by rotating a shift drum.
(従来技術)
自動二輪車などで多用されているシフトドラム式変速機
では1通常バック装置を設けていない。(Prior Art) Shift drum type transmissions, which are often used in motorcycles, are not usually provided with a reversing device.

体を別設針にしなければならないという問題が生じる。There have conventionally been small three- or four-wheeled vehicles equipped with a transmission-equipped engine such as Kono for traveling on rough terrain, but in this case, a backup device may be required. When this backing device is integrated into the transmission, a problem arises in that the entire engine must be provided separately.

て面倒になる。Therefore, it is conceivable to interpose a forward/reverse switching mechanism between the transmission without a backing device and the rear wheel transmission, but in this case, after performing the forward/reverse switching, the shift drum of the transmission is set to the appropriate gear. Switching would require two steps of operation, which would be cumbersome.

An object of the present invention is to provide a reversing device for a vehicle that simplifies driving operations when switching between forward and reverse directions.

On the other hand, an interlocking mechanism is provided which rotates the shift drum to a predetermined stage in conjunction with switching of the forward/reverse switching mechanism.

ット36が逆転スる。When switching to reverse, the shift drum 30 is placed in the neutral position. At this time, the gear 78 fixed to the connecting rod 76 is in the state shown in FIG. When the pedal of the switching lever 62 is pushed down toward the side of the vehicle body with the left foot, the gear 80 engages with the gear 78 and the gear 78. Connecting rod 76° The shift drum 30 is rotated counterclockwise as shown in FIGS. 1 and 3, and in this state the detent mechanism 6
8.70. Therefore, the transmission 16 switches to a predetermined low speed gear 1, for example, the first gear, and the cylindrical cam 6° moves the fork 54 and the slider 46 toward the outside of the vehicle body. Therefore, the rotation of the countershaft 22, which is the output shaft, is transmitted to the gear 44 via the reverse gear group 50, 52, and the sprocket 36 is rotated in the reverse direction.

本実施例では歯車78.80により連動機構74を構成
し、変速機16の中立位置でのみ後進への切換えが可能
となっているので安全性が向上する。In this embodiment, the interlocking mechanism 74 is composed of gears 78 and 80, and switching to reverse is possible only when the transmission 16 is in the neutral position, improving safety.
また前進へ戻す時もシフトレバ−32の操作のみで自動
的に後進位置から前進位置にスライダ46が移動するの
で、前進への復帰操作も簡単で速やかに行える。Further, when returning to the forward direction, the slider 46 is automatically moved from the reverse position to the forward position by simply operating the shift lever 32, so that the return operation to the forward direction can be performed easily and quickly.
