Hereinafter, the structure for restraining mechanism 345 is described in detail.Containing part 351 has guiding elements 351a and protrusion component 351b.Guiding elements 351a is grasped from the position that advanced side courses of action 324a (bar guide groove 324) deviates downwards along advanced side Make path 324a to extend and movement can be slided along the longitudinal direction.Protrusion component 351b is located at the top of guiding elements 351a Portion, and advanced side courses of action 324a can be proceeded to.Guiding elements 351a and protrusion component 351b are by making a rodlike structure The top end part of part (for example, pole) is bent and is formed.
The bottom surface of side panel 322 be equipped be equivalent to " support bracket " of the invention bracket 346 and be equivalent to this hair The bracket 347 of bright " other support brackets ".As shown in figure 26, bracket 346 is set to bar guide groove 324 and bar guide groove when looking down Between 325.As shown in Figure 27, Figure 28, bracket 346 is by being flexed into side view U-shaped for one piece of metal plate, and then by two upper ends Side and rear side are flexed into flange shape and are formed forwards.Bracket 346 is fixed on side panel 322 via the flange part of front and back end Bottom surface.The front surface part and rear face portion of bracket 346 are located at different positions along the longitudinal direction, have through hole 346a. The state that two through hole 346a are overlapped when being formed as from front-rear direction.Guiding elements 351a is to run through two through holes 346a, and in the state support of front-rear direction movement free to slide (free to slide) in bracket 346.
As shown in figure 26, bracket 347 is set to the left side of advanced side courses of action 324a when looking down, that is, is set to across preceding The side opposite with bracket 346 into side courses of action 324a.As shown in Figure 27, Figure 28, bracket 347 is by rolling over one piece of metal plate Song is formed at L-shaped warpage.Bracket 347 is fixed on the bottom surface of side panel 322 via one side of L word.In the L word of bracket 347 The other side is formed with long hole 347a along the longitudinal direction.Long hole 347a is run through in the top end part for protruding component 351b, protrudes component One end of 351b is supported on guiding elements 351a, and the other end (top end part) is in front-rear direction movement (free skating free to slide It is dynamic) state support in bracket 347.
As shown in figure 27, bracket 347 is configured and is positioned to: the front end of long hole 347a is located at than advanced side courses of action 324a Front end also on the front at least protrude component 351b diameter length more than position, and the rear end of long hole 347a be located at than restrain The position of the diameter length of component 351b is also protruded rearward in position.
As shown in Figure 26~Figure 28, link rod part 352 has arm member 352a and bar component 352b.Arm connection is fixed on receipts The lower end of clutch lever 343 is cut, can be swung together around swinging center X with harvesting clutch lever 343.Bar portion is prolonged along front and back It stretches, rear end be connected to arm member 352a in a manner of it can rotate around the first axle center Y1, and front end is with can be around second The mode of axle center Y2 rotation is connected to the rear end of guiding elements 351a.Bar component 352b is in the middle part for slightly leaning on front end Divide curved rod member (for example, pole) downwards.
When harvesting clutch lever 343 is located at clutch off-position (referring to (a) of Figure 27), when side view, arm in from For swinging center X downwards and gently towards the state that front extends, harvesting clutch lever 343 is located at clutch communicating position (reference (b) of Figure 27) when, when side view, arm is in the state rearward and gently towards top extended from swinging center X.On the other hand, The front end of bar component 352b is attached at and slides mobile guiding elements 351a along the longitudinal direction, therefore gathers in clutch lever 343 When being operated into clutch communicating position (referring to (b) of Figure 27) from clutch off-position (referring to (a) of Figure 27), on one side The upper and lower position of front end is maintained rearward to move on one side, and rear end portion side is swung upwards around the second axle center Y2.
That is, link rod part 352 is configured to: harvesting clutch lever 343 from clutch off-position (referring to Figure 27 (a)) quilt When operating clutch communicating position (referring to (b) of Figure 27), then (observed along the direction of swinging center X) when side view, first axle Heart Y1 passes through the rear side of swinging center X, and connects the straight line L of the first axle center Y1 and the second axle center Y2 to cross over swinging center X Mode it is mobile.Therefore, harvesting clutch lever 343 is when being operated into clutch communicating position (referring to (b) of Figure 27), right Forwards in the case where the pulling force in direction, arm is pulled to front side, left side view by bar component 352b for bar component 352b effect When with as the tendency that rotates counterclockwise.But as described above, connection is fixed with the harvesting clutch lever 343 of arm member 352a It is connected to the front end 326a of bar guide groove 326, therefore cannot be rotated counterclockwise.It cannot square side movement further along.
By the above structure, protrudes component 351b and be in when gathering in clutch lever 343 and being operated into clutch off-position The state that the front side of side courses of action 324a that moves forward retreats, when harvesting clutch lever 343 is operated into clutch connection position When setting, by the swing of arm member 352a, guiding elements 351a is pulled to rear via bar component 352b and slides movement, protrusion Component 351b proceeds to the containing position of advanced side courses of action 324a.Therefore, as shown in figure 28, advance in protrusion component 351b It has arrived under the state (harvesting clutch 310A is connected state) for restraining position, even if main shift lever 341 is wanted from neutral path The side 324b is moved to advanced side, also due to being connected to protrusion component 351b restraining position, cannot grasp further along into side Make.Containing position and neutral road but even if harvesting clutch 310A is operated by connection, in the courses of action 324a of advanced side The operation of path between diameter 324b and the main shift lever 341 on retrogressing side courses of action 324c is also free.
It should be noted that when using restraining mechanism 345 and creating a diversion, even if wanting main shift lever 341 from containing Position operates side of marching forward by force, since harvesting clutch lever 343 is connected to the front end 326a of bar guide groove 326, operation Main shift lever 341 will not be operated surprisingly to advanced side than restraining position also.
(for restraining the relationship of mechanism and travel speed)
Based on Figure 29, the relationship for restraining mechanism 345 and travel speed is illustrated.As described above, no matter secondary speed change fills Set 309C speed change state how (either higher speed gear state or low speed speed change state), restraining mechanism 345 all can be with Clutch 310A operation is gathered in connected state, reduces the operating area of the advanced side of main shift lever 341.Pass through main transformer as a result, The maximum output value that speed variator carries out is lower, as a result, can be presented by main transformer speed variator and secondary speed-changing device 309C Maximum speed is lower.
Specifically, in the case where secondary speed-changing device 309C is in " higher speed gear state ", if harvesting clutch 310A is " dissengaged positions " (restraining mechanism 345 is " non-containing state "), then as shown in " Mode A ", the travel speed of advanced side Region becomes " 0 "~" V1 (maximum speed) ", if harvesting clutch 310A is that " connected state " (restraining mechanism 345 is " to restrain State "), then as shown in " mode C ", the travel speed region of advanced side becomes " 0 "~" V3 (maximum speed)=k × V1 ".? This, " k " is the coefficient for meeting " 0 < k < 1 ".
Even if secondary speed-changing device 309C is in " low speed speed change state ", similarly, if harvesting clutch 310A is " cutting State " (restraining mechanism 345 is " non-containing state "), then as shown in " Mode B ", the travel speed region of advanced side becomes " 0 " ~" V2 (maximum speed) ", if harvesting clutch 310A is " connected state " (restraining mechanism 345 is " restraining state "), such as Shown in " mode D ", the travel speed region of advanced side becomes " 0 "~" V4 (maximum speed)=k × V2 ".
As described above, restraining mechanism 345 by having, the connection to gather in clutch 310A is cut off as condition, is presented Four travel speed regions of twice of the speed change number of regions of secondary speed-changing device 309C can be presented in two kinds of velocity bands.Therefore, It, can be by a left side of gearbox 309B compared with gear columns to be set as to four situations in the secondary speed-changing device 309C in gear type Right width design obtains smaller, or gear thickness can become larger and improve the durability of secondary speed-changing device 309C.In addition, In the state that harvesting portion 303 is being driven, travel speed will not speed change be certain travel speed (V3, V4) more than, therefore Mobile devices 302 will not reach appropriate travel speed or more due to maloperation, can prevent engine 308 negative by height in advance Lotus.
Also there are other application methods for restraining mechanism 345.For example, desired low from secondary speed-changing device 309C is operated into Fast speed change state drives harvesting portion 303 and many high speed row fastly than status speed In the case where the state sailed, if on the basis of will gather in clutch 310A operation to connected state, by secondary speed-changing device 309C is operated to higher speed gear state, then can efficiently speedup to appropriate travel speed.However, being forgotten sometimes by secondary speed change Device 309C is operated to higher speed gear state.But due to have restrain mechanism 345, even if due to want speedup and incite somebody to action Main shift lever 341 operates side of marching forward, and can not operate the position for also leaning on speedup side than restraining position, can remind driver Secondary speed-changing device 309C is in low speed speed change state, and driver can be reminded secondary speed-changing device 309C operation to higher speed gear shape State.
(another embodiment of third embodiment)
In the above-described embodiment, speed change state (the either high speed regardless of secondary speed-changing device 309C is listed Speed change state or low speed speed change state), if harvesting clutch 310A becomes connected state, restraining mechanism 345 all can be at For the example for restraining state, but the present invention is not limited thereto.For example, becoming the premise of containing state as mechanism 345 is restrained Condition can also add the condition of " secondary speed-changing device 309C is in higher speed gear state ".
Although for example can be in this case, not illustrated especially such as flowering structure: by mechanical linkage or Person's electric control cuts off the company of guiding elements 351a and bar component 352b when secondary speed-changing device 309C becomes low speed speed change state Knot connects the connection of guiding elements 351a and bar component 352b when secondary speed-changing device 309C becomes higher speed gear state.
For the containing mechanism 345 of the other embodiments and the relationship of travel speed, it is illustrated based on Fig. 8.In pair In the case that speed change gear 309C is in " higher speed gear state ", if harvesting clutch 310A is that " dissengaged positions " (restrains machine Structure 345 is " non-containing state "), then as shown in " Mode A ", the travel speed region of advanced side is " 0 "~" V1 (maximum speed Degree) ", if harvesting clutch 310A is " connected state " (restraining mechanism 345 is " restraining state "), such as shown in " mode C ", The travel speed region of advanced side becomes " 0 "~" V3 (maximum speed)=k × V1 ".Here, " k " is to meet " 0 < k < 1 " Coefficient.
But if secondary speed-changing device 309C is " low speed speed change state ", restrains mechanism 345 and do not work, therefore regardless of Harvesting clutch 310A is " dissengaged positions " (restraining mechanism 345 is " non-containing state "), and still " connected state " (restrains mechanism 345 be " restraining state "), such as shown in " Mode B ", the travel speed region of advanced side becomes " 0 "~" V2 (maximum speed) ".
In this case, the generation more particularly to prevent the following state of affairs in advance, that is, be in high speed in secondary speed-changing device 309C and become Fast state and the homework department of big driving force is needed to be driven, when engine 308 is in the state of high load capacity, main transformer Speed variator is operated to high-speed side, and engine 308 is caused further to be applied load.
