Abstract

PURPOSE:To stop the rotation of a shift rod simply and securely by driving a pin into said shift rod through a sleeve and a collar part, to fix said shift rod by stopping rotation. CONSTITUTION:An operating member 20 is rotatably fitted over a shift rod 2 which makes shift between a two-wheel drive and a four-wheel drive. With the collar part 21 of the operating member 20 being inserted into the opening part 24 of a sleeve 23, with a spring 25 interposed in between, a roll pin 20 is driven into the rod 2 in a direction perpendicular to the shaft, through the cut groove 26 of the sleeve 23 and the collar part 21, to fix the operating member 20 to the rod 2. The interposition of the roll pin 22 in the cut groove 26 as an opening of the sleeve 23, restrains the movement of the sleeve 23 in a direction around the shaft, with respect to the rod 2. Further, a snap ring 27 is fitted to the outer periphery of the rod 2, to restrain the axial movement of the sleeve 23 which is pushed rightward by the spring 25.

る。That is, i! is applied to the sleeve 7 of the shift lever A-6. The waiting mechanism for QIJ is to insert the shift rod 2 into the cylindrical part 8 of the sleeve 7, and to insert the snap rings 11 and 12 into the cylindrical part 8 on both sides with collars 9 and 10 interposed on both sides of the cylindrical part 8.
The collar 11 is further secured with a snap ring 13 fitted on the shift rod 2 on the outside, and the collar 9.10
It has a structure in which a sub-ring 14 is inserted between the two. Further, a bracket 15 is fixed to the left side of the sleeve 7 by driving a roll bin 16, a shift rod 3 is inserted into a plate portion 15a of the bracket 15, and the shift rod 2 is prevented from rotating by inserting the bracket 15 into the shift rod 3. is being carried out.

。The action of such a waiting mechanism is in two-wheel drive when the ball 18 is fitted into the ball groove 17 of the shift rod 2 as shown in the figure, and the ball is activated by moving the actuating member 4 to the left in conjunction with the shifter 1 operation. At the position where the ball 1B fits into the groove 19, the shift fork 6 switches to four-wheel drive. That is, the shift fork 6 causes a coupling sleeve of a not-shown synchronizing mechanism (four-wheel drive side only) to synchronously mesh with a four-wheel drive side clutch gear. In this switching to four-wheel drive, the sleeve 7 is moved together with the shift rod 2 under the pressure of the bracket 15 fixed on the right side.

3, J: Only the recolor 9 moves, and by compressing the spring 14 in the sleeve 7, the shift rod 2 returns to the initial position with the sleeve 7 remaining. Subsequently, when the coupling sleeve is synchronized with the 2-width side clutch gear in the four-wheel drive state, the restoring force of the compressed spring 14 pushes the sleeve 7 back to its initial position, and the shift 1 is shifted by the return of the shift A-7. The coupling sleeve engages the 2-width side clutch gear and switches to 2-wheel drive.

If you do not drill the shaft hole in the coushing and assemble the shift rod so that the distance between the shafts of the rod is accurate, the bracket will be twisted when the bracket is inserted, and the movement of the shift rod will be restricted by the bracket. There was a problem with being blocked.

~ The fork 6 is driven into four-wheel drive (operated while left in place). The member 20 and shift rod 2 move to the right, and the operating member 20
The collar part 2'1 is pushed into the open cylindrical part 24 of the sleeve 23 and compresses the spring 25, and the restoring force of the compressed spring 25 causes the sleeve 23, that is, the shift lever A
The vehicle is in a so-called samurai state in which the steering wheel 6 is biased toward the rightward two-wheel drive (11) side.

り由めＪることができる。Next, to explain the anti-rotation effect of the shift rod 2 in the waiting mechanism shown in FIG. Since the shift rod 2, the actuating member 20, and the sleeve 23 of the shift fork 6 are located in the cut groove 26 formed on the side where the roll bin 22 is driven, the shift rod 2, the actuating member 20, and the sleeve 23 of the shift fork 6 are integrated against movement around the axis when the roll bin 22 is driven. and the shift fork 6 has four wheels (not shown).
12-Since it is fitted into a groove A-shaped formed on the outer periphery of a coupling sleeve (not shown) that switches between drive and two-wheel drive, the shift lever A is fitted into the coupling sleeve.
The movement of the shift rod 6 around the axis is restricted, and the shift rod 2 can be rotated.

いる。Therefore, unlike the conventional device, there is no need for a rotation prevention structure in which the bracket 1 fixed by driving the pin 22 into the shift 1 rod 2 extends to the position of the other shift 1 rod 3 and is inserted into the shaft. : The number of parts is reduced by not using ~, and the roll bin 22 only needs to be driven into one place, resulting in a significant reduction in the number of processing steps and assembly steps. Further, the collar member constituting the waiting mechanism forms a collar portion 21 integrally with the operating member 20,
In addition, since a portion of the other collar is integrally formed on the closed side of the open cylindrical portion 24 formed in the sleeve 23, there is no need to prepare the collar member as a separate component as in conventional devices. In this respect as well, the number of parts is reduced, which reduces the number of processing and assembly steps, and furthermore, a simple structure is realized in which only one snap ring is required.

A part of the collar is inserted via a spring into the opening of the sleeve formed integrally with the shaft of the shift fork, and the collar is shifted from a direction perpendicular to the shaft to the sleeve insertion site through the sleeve and part of the collar. Since the pin is driven into the rod to prevent it from rotating, there is no need for a locking mechanism that pushes the other shift rod onto the bracket fixed to the shift rod. A part of the collar of the operating member used for Shift 1~Fork sleeve is integrated around the axis of Shift 1~Rondo by driving a bottle, and then Shift 1~
