FIG. 1 is a side view around a control section of a combine, which is an embodiment of the present invention, FIG. 2 is a vertical sectional view of a variable speed traveling device in this case, and FIG. FIG. 4 is a plan view of the shift guide portion of the continuously variable transmission mechanism. The transmission device 1 will be described. The transmission device 1 transmits the power of the input shaft 2 to the left and right traveling axles 3 and 3, which are the final output shafts. In addition, it has a mechanical friction type continuously variable transmission mechanism 4 and a gear slide type forward / reverse rotation switching mechanism 5. In addition to this, in this transmission path, a brake mechanism 6 that applies a brake to a certain transmission shaft and a downstream side of the brake mechanism 6 are provided, and the above power is branched to the left and right traveling axles 3 and 3 to be intermittently connected. A side clutch brake mechanism (hereinafter, simply referred to as a side clutch mechanism) 7, 7 and the like which is effective for braking when disconnected is also provided. The mechanical friction type continuously variable transmission mechanism 4 has the following structure that is inoperable when stopped. That is, an umbrella-shaped planet cone 8 is arranged on the circumference of a planet, and the input disc 10 and the output disc 11 connected to the input shaft 2 and the output shaft 9 are pressed against the front and rear surfaces thereof, respectively, and the planet cone 8 is attached. Ring 1 on the outer circumference
By pressing 2 and changing the position of this ring 12, the contact position of the planetary cone 8 is changed, thereby obtaining a gear shift,
It is of the so-called differential planetary mechanism type. The mechanical friction type continuously variable transmission mechanism 4 of this type is small in size but has a wide speed change range, and is particularly excellent in such a purpose because it can output 0 revolutions. When the power from the side is cut off, the frictional force (pressure contact force) between the ring 12 and the planetary cone 8 is too large, and the ring 12 cannot be moved, that is, the gear shift operation cannot be performed.
It is called an inoperable type when stopped. By the way, only the mechanical friction type continuously variable transmission mechanism 4 is housed in the sub case 42 adjacent to the upper portion of the main case 40 with the side wall 41 as a partition wall.
And make up the mission case. The gear slide type forward / reverse rotation switching mechanism 5 is a pair of transmission shafts 13 and 14 in the transmission path (the transmission shaft 13 is provided with the output shaft 9 of the mechanical friction continuously variable transmission mechanism 4 described above. Good) during vice axis 1
5, the slide gear 16 fitted to the one transmission shaft 13 is selectively meshed with the gears 17 and 18 fitted to the other transmission shaft 14 and the auxiliary shaft 15, respectively. It is a type that imparts forward and reverse rotations to 14. On the other hand, the operation of the mechanical friction type continuously variable transmission mechanism 4 and the forward / reverse rotation switching mechanism 5 is performed by using the single transmission lever 1
9. First, the gear shifting operation of the mechanical friction type continuously variable transmission mechanism 4 is performed by moving the ring 12 along the top surface of the planetary cone 8 as described above. The holder 20 and the gear shift lever 19 are connected by a link mechanism 21 or the like. The speed change lever 19 is, as shown in FIG.
Although it is guided by a guide guide 22 having a substantially H shape, this continuously variable transmission operation is set to be possible by the vertical motion component on both the F side (forward) and the R side (reverse). It's done (the faster you push it forward). Next, regarding the switching operation of the forward / reverse rotation switching mechanism 5, the guide guide 22 described above is used.
The auxiliary guide guide 24 is provided rotatably in the left-right direction with the speed change lever 19 inserted into a long hole 23 (allowing the vertical movement of the speed change lever 19 in the entire vertical direction) formed in the lower part of the vertical direction. Then, the sub guide guide 24 and the operation fork 25 linked to the slide gear 16 are connected by the link mechanism 26. Accordingly, if the shift lever 19 is moved in the left-right direction along the lateral passage of the H pattern of the guide guide 22, that is, if a lateral motion component is generated, the auxiliary guide guide 24 is also rotated in the left-right direction. Along with that, the link mechanism 26 and the like perform a predetermined operation, and the operation fork 25,
Therefore, the slide gear 16 is slid to switch between forward and reverse rotation. Further, the clutch body 2 which is the side clutch mechanism 7 and 7 is engaged with and disengaged from the transmission gear 27 which constitutes the transmission system by sliding on the transmission shafts 28 and 28.
Arms 31, forks 30, 30 for operating 9, 29
31 is fixed and the intermittent operation is performed by a remote predetermined rotation operation of the arms 31, 31.
In addition to this, a stop pedal 33 is provided near the foot of the control unit 32 such as a combine having the above-described configuration, and the stop lever 33 and the shift lever 19 and the side clutch mechanisms 7, 7 of the mechanical friction continuously variable transmission mechanism 4 described above. The arms 31, 31 are interlocked as follows. That is, the arm 34 is provided in the link mechanism 21 or the like adjacent to the speed change lever 19, and the wire 35 is stretched between the arm 34 and the stop pedal 33 (a cushioning spring 36 or the like is interposed therebetween). , The arms 31 and 31 are also connected to each other by a wire 37 or the like (if necessary, a buffer spring or the like is also interposed therein). Accordingly, when the stop pedal 33 is stepped on, the movement is transmitted to the gear shift lever 16 and the arms 31, 31 via the wires 35, 37, and the gear shift lever 16 is moved to the neutral side, that is, the mechanical friction continuously variable transmission mechanism 4. To the low speed side,
Also, the side clutch mechanisms 7 and 7 act on the disengagement side, respectively. In the above, it is needless to say that the tension of the wire 35 or the like is appropriately offset in the left-right direction so as not to get in the way of the foot or the like, and around the stop pedal 33, this shifts beyond the specified value. A stopper 38 is provided to regulate the position of the stop pedal 33, and the stop pedal 33 is always springed toward the original position by a return spring 39. By the way, according to the present invention, in the above, the sub-case 42 accommodating the mechanical friction type continuously variable transmission mechanism 4 is adjacent to the main case 40.
At this time, as can be seen from FIGS. 1 and 2, the forward / reverse rotation switching mechanism 5 housed in the upper portion of the main case 40, the support shaft 43 of the operation fork 25 attached thereto, the auxiliary shaft 15, and the downstream side. The transmission shaft 14 to the side side clutch mechanism 7, 7 is arranged so as to be included in the side projection plane of the mechanical friction type continuously variable transmission mechanism 5 housed in the sub case 42. Further, the side clutch mechanisms 7, 7 are arranged so as to be included in the downward projection plane of the mechanical friction type continuously variable transmission mechanism 4 and the forward / reverse rotation switching mechanism 5.

First, the forward / reverse rotation switching mechanism and the members associated therewith are provided in the side projection plane of the mechanical friction continuously variable transmission mechanism.
Also, since the side clutch mechanism is housed in the upper projection plane of both of these mechanisms, it is possible to make an aggregated installation space that does not project vertically, horizontally, forward and backward, and to make the mission case significantly smaller. it can. In this respect, in the case where the gear and the operating fork are installed at a position outside the projection plane, the size of the gear and the operating fork must be increased to reach the mating member, which further increases the size of the mission case. Further, this improves the weight balance of the mission case and is easy to handle when moving during assembly. Then, by doing so, the span of the support shaft, counter shaft, transmission shaft, etc. of the operation fork can be shortened, and both ends can be firmly supported by the side walls of the main case and the sub case. Thrust load can be reduced, which is advantageous in strength. Therefore, there is also an advantage that these members can be further downsized.
