As described in Figure 5, arm spare 22 is such as making with metal lath, and the intermediate portion is positioned on that part of outer circumferential face directly over the stop pin 7a around speed change lever 7.The 22a of first portion of arm spare 22 is along the vertical setting of the axis of speed change lever 7, and extends towards stopping device 20 from that part of outer peripheral portion facing to stopping device 20 of speed change lever 7.The second portion 22b and the speed change lever 7 of arm spare 22 are horizontally disposed with meeting at right angles, and extend back from that part of outer peripheral portion that is positioned on the automotive back of speed change lever 7.The 22a of first portion that extends towards device 20 plays a part a gear shift arm, and the second portion 22b on automotive back plays a part a selection arm.Select arm 22b to equal an actuating arm.
Next describe stopping device 20, Fig. 6 has shown the outward appearance of stopping device 20, and Fig. 7 has shown and installs 20 internal structure.One box-like housing 30 is installed on the upper surface of base plate 6, along the longitudinal extension of car body.Housing 30 is the box of a rectangular prism shape in form, in its one side opposite with speed change lever 7 one opening 30a is arranged.One block bearing 32 inserts housing 30 by its opening 30a.The main body 33 of stopping device 20 forms by housing 30 and bearing 32 are combined.One step 34 this as being formed in the front end of bearing 32, herein, be inserted in bearing 32 in the housing 30 facing to speed change lever 7.Step 34 is recessed from a sidewall 30b of housing 30.One bar chamber 35 is made of the space that the sidewall 30b of step 34 and housing 30 surrounds.
One slid chamber 36 is formed on the rear section of bearing 32, there, is inserted in bearing 32 in the housing 30 facing to a lateral margin of selecting arm 22b.Just the end face of 32 office, insertion part extends towards its opposite one side along vehicle width direction from bearing in chamber 36.Such as, the form of chamber 36 is on earth a square hole.The movable part 21 that is used to select is by the internal surface supporting of slid chamber 36, to slide in the choice direction of speed change lever 7.More specifically, the proximal part 21a of movable part 21 is essentially the corresponding lath of shape of its cross section and slid chamber 36 in form.The proximal part 21a of movable part 21 is inserted in the slid chamber 36 slidably.
With the distal portions of the movable part 21 selected pass on the side arm of housing 30 square hole 37 and towards speed change lever 7 projections.Breakthrough portion 39 with a hole 38 forms in the distal portion of movable part 21.Vertically or along the movement direction of speed change lever 7 extend along sluice gate 11 and 13 in hole 38.The selection arm 22b of arm spare 22 passes hole 38 slidably.Being dimensioned to of hole 38 can make that when speed change lever longitudinally moves arm 22b can motion longitudinally in hole 38 in sluice gate 11 or 13.Simultaneously, the size design in hole 38 become when speed change lever in transition sluice gate 12 during along transverse movement, another lateral margin of arm 22b can cooperate with the inner wall surface 38a in hole 38.Therefore, when speed change lever 7 moved in sluice gate 12, the whole movable part that is used to select 21 can be along sluice gate 12 and is moved at the longitudinal direction of slid chamber 36.Like this, handled when travelling longitudinally under the automatic or manual shift mode when speed change lever 7, movable part 21 breaks away from speed change levers 7, never can follow the motion of speed change lever 7.Only at speed change lever 7 between automatic and manual shift mode during conversion, movable part 21 just moves along the width direction (laterally) of car body integrally with speed change lever 7.Select arm 22b long enough,, select arm 22b to keep being inserted in the hole 38 always when speed change lever during in automatic shift mode or the longitudinal movement of manual shift mode lower edge.Hole 38 can be substituted by the groove (not shown) of an open-top, and this groove is formed in the distal portions of movable part 21 and extends longitudinally.In this case, allow arm 22b pass this groove so that carry out longitudinal movement.
The movable part 21 that is used to select has a fixed mechanism 40 at its proximal part 21a.Mechanism 40 can produce a retention force, speed change lever 7 is fixed on any end of sluice gate 12 as a fixing device.Fixed mechanism 40 has counterpart 42.Counterpart 42 is assemblied in the recess with projection or withdrawal, and this recess forms on the wall of proximal part 21a of the movable part 21 that is centered on by slid chamber 36, such as a side that forms in proximal part 21a.Force counterpart 42 to release recess by a pressure spring 41.Can be used as this counterpart 42 such as, steelie or pin with rounded ends.
More specifically, a hole 41a forms in a side of the movable part 21 that is used to select and passes across its thickness, shown in Fig. 9 A.Hole 41a contains counterpart 42 and is used for promoting the pressure spring 41 of counterpart 42.The a pair of recess 43 that is used for admitting counterpart 42 forms in the inner arm face of slid chamber 36, corresponds respectively to two positions, and when speed change lever 7 moved to any end of sluice gate, counterpart 42 alternately was positioned at this two positions.Such as, each recess 43 is a groove in form, is preferably the V-shaped groove of a vertical extension.When movable part 21 along with speed change lever 7 from an end motion of sluice gate 12 during to the other end, counterpart 42 breaks away from from one of recess 43, and cooperates with another.As a result, movable part 21 remains on its position according to the position of another recess 43, fixes speed change lever 7 thereby produced a retention force.Be used as with small ball under the situation of counterpart 42, each recess 43 can be made of a recessed sphere.By utilizing the change that enters or leave the retention force of the speed change lever 7 that recess 43 produces by counterpart 42, produced a kind of engaging in the beginning of mode transformation operation (conversion between automatic shift mode and manual shift mode) with when finishing and felt.
On the wall of side of the movable part 21 that is used to select and slid chamber in contrast 36, pair of contacts is arranged respectively, an i.e. suitable contact 44a and a fixed contact therefor 44b, such as, when movable part 21 arrives the position of its manual shift mode, these contacts 44a and 44b engage, to realize electrical connection each other.On the other hand, when movable part 21 was used for the position of automatic shift mode to it, contact 44a and 44b threw off and are not electrically connected.Especially, shown in Fig. 9 B, movable contact 44a is made of the movable contact plate 44c of basic U-shaped.Contact plate 44c two end portions is slidably inserted in a pair of slit 44d, and slit 44d lays respectively near the side of the movable part 21 the counterpart 42.The one contact spring 44e that is made of disc spring is arranged between the lateral parts of movable contact plate 44c back side central authorities and the movable part 21 opposite with it.Spring 44e forces plate 44c to make it to release towards fixed contact therefor 44b.More particularly, a hole 44f who is used for spring 44e forms in the lateral parts of two movable parts between the slit 44d, and the end of contact spring 44e is inserted in the 44f of hole slidably.Whole spring 44e keeps being compressed between movable contact plate 44c and the movable part 21.Fixed contact therefor 44b is connected to such as the substrate 44g that is made of a printing plate.Substrate 44g utilizes such as screw 44i and is fixed on wall portions corresponding to the 36b of slid chamber of contact plate 44c.
A pair of contacting part 44h is arranged on the surface of substrate 44g, and when movable part 21 is positioned at one when being used for the position of manual shift mode, this just has been electrically connected when contacting part 44b is contacted with movable contact plate 44c.When movable part 21 moved to the position that is used for automatic shift mode, this separately and no longer was electrically connected from contact plate 44c contacting part 44h.Substrate 44g is embedded on the wall portions of slid chamber 36, with the motion of obstruction free movable part 21.Pairing automatic shift mode in the position of movable part 21 or manual shift mode can indicate the electrical connection between contact 44a and the 44b or the signal that break away to connect and being detected out in response to one.Movable and fixed contact therefor 44a and 44b have constituted mode transformation system 24, are used for the acquisition model figure signal.
As shown in Figure 5, a neutral gear fixed mechanism 23 is contained in the bar chamber 35.Mechanism 23 comprises a pair of movable part 45a and the 45b that is used for gear shift, and each all has the profile that is similar to half fan-shaped fundamental triangle.These movable parts 45a and 45b are arranged in the bar chamber 35, to clamp a therebetween interdiction piece 32a (being shown among Fig. 7).Interdiction piece 32a forms on the end face such as the insertion portion of the bearing 32 in the housing 30.Interdiction piece 32a one corresponding to the position of the neutral position in the manual sluice gate 13 towards movable part 45a and 45b projection.In other words, movable part 45a and the 45b that is used for gear shift is arranged in moving direction along sluice gate 13.Parallel supporting axle 46 on the internal surface of a pair of sidewall 30b that is formed in housing 30 be inserted in the movable part 45a of their correspondences and 45b rotationally each in the underpart.Movable part 45a and 45b be by axle 46 supporting, with can shake to or shake from interdiction piece 32a (on the autokinesis direction of manual sluice gate 13).A pair of jaw 45c and 45d are respectively from the projection that makes progress of the adjacent portion of the upper end portion of movable part 45a and 45b.These jaws 45c and 45d are in the projection by the longitudinal extension slit 30 on housing 30 roofs above the housing 300.The longitudinal length of slit 30c is designed so that the jaw 45c that shakes around axle 46 and the displacement of 45d can not hindered.
The jaw 45c of projection above housing 30 and the 45d t that keeps at a distance each other, the width that this depends on interdiction piece 32a can pass through gear shift arm 22a between jaw.This distance or clearance t can be inserted between jaw 45c and the 45d arm 22a when speed change lever 7 moves to neutral position 13a in the 3rd sluice gate 13 from transition sluice gate 12.
Be used for the movable part 45a of gear shift and 45b utilize be arranged in movable part separately the pressure spring 47a between the wall of side surface and bar chamber 35 and 47b elastic force and promoted by the neutral position 13a in manual sluice gate 13.Like this, jaw 45c and 45d are maintained at neutral position 13a, and are subjected to spring 47a and 47b from both sides, promptly promote from front side and rear side.Therefore, when gear shift arm 22a was inserted between the jaw 45c of the movable part 45a that is used for gear shift and 45b and the 45d, arm 22a was flexibly pushed to neutral position 13a, and like this, speed change lever 7 just is maintained on the 13a of position.Be used for movable part 45a of gear shift and the effect that spring 47a plays first pushing device, another movable part 45b and spring 47b are as second pushing device.
When the neutral position 13a of speed change lever 7 in manual sluice gate 13 moves on to raising speed position 13b or decelerate position 13c, only be positioned at the movable part 45a that is used for gear shift and the 45b that handle on the side and swing to position 13b or 13c from neutral position 13a in the mode that cooperates with arm 22a.When this moment, pressure spring 47a or 47b were compressed, produced a reaction force that makes speed change lever 7 return to neutral position.
On the side of the preceding movable part 45a that is used for gear shift and 32 end faces of bearing in contrast, be furnished with pair of contacts respectively, i.e. a movable contact 48a and a fixed contact therefor 48b.When movable part 45a when moving to raising speed position 13b, these contacts 48a and 48b are electrically connected mutually.When movable part 45a got back to neutral position 13a, contact 48a and 48b threw off and no longer are electrically connected.The movable contact 49a and the fixed contact therefor 49b that have same conducting function with contact 48a and 48b also are arranged in the side of the back movable part 45b that is used for gear shift and the end face of bearing on the other side 32 respectively.Figure 10 has shown the structure of movable contact 48a and 49a and fixed contact therefor 48b and 49b.Because activity and fixed contact therefor 48a and 48b are identical respectively at textural and activity and fixed contact therefor 49a and 49b, below contact 49a and 49b will be described typically.
Movable contact 49a is made of the movable contact plate 55 of a basic U-shaped.The two end portions of contact plate 55 is inserted in a pair of slit 56 slidably, and this lays respectively on the side surface of movable part 45b slit 56.Between the side of the back of movable contact plate 55 central authorities and movable part 45b on the other side, has a contact spring 57 that constitutes by disc spring.Spring 57 forces plate 55 to be released from slit 56.More specifically, a hole 57a who is used for spring 57 is formed in the lateral parts of two movable part 45b between the slit 56, and an end of contact spring 57 is inserted in the 57a of hole slidably.Whole spring 57 keeps being compressed between movable contact plate 55 and the movable part 45b.Fixed contact therefor 49b is such as being connected on the substrate 58 that is made of a printing plate.Substrate 58 is by the wall 35a facing to the side separately of movable part 45a and 45b that is fixed in bar chamber 85 such as screw 58a.
More specifically, contact segment 59 is arranged on the surface of substrate 58, corresponding to each position of the movable contact plate 55 that is arrived when the movable part 45a that is used for gear shift and 45b move to raising speed or decelerate position 13b or 13c.When a movable part 45a was positioned at raising speed position 13b, preceding movable contact plate 55 contacted with preceding contact segment 59, thereby preceding contact segment is electrically connected mutually.When another movable part 45b was positioned at decelerate position 13c, back contact plate 55 contacted with back contact segment 59, from contact segment 39 disengaging electrical connection mutually then.When movable part 45a and 45b were positioned at neutral position 13a, its contact plate 55 was separately thrown off with contacting part 59, and like this, contacting part 59 is just thrown off mutually and is electrically connected.Substrate 59 is embedded in below the wall surface 35a of bar chamber 35, is used for the movable part 45a of gear shift and the motion of 45b in case its hinders.One raising speed or reduce-speed sign are output in response to an electrical conduction signal that obtains from movable contact 48a and 49a and fixed contact therefor 48b and 49b.Movable contact 48a and 49a and fixed contact therefor 48b and 49b have constituted gear shift transformation system 25.
As shown in Figure 7, movable contact 44a, 48a and 49a and fixed contact therefor 44b, 48b and 49b are connected in a shift controller 51 (see figure 1)s by a flexible cord 50 of drawing from bearing 32 and the connector 50a that is connected in flexible cord 50 ends, and it is by constituting such as a microcomputer.Handle control gear 51 from the mode transformation signal of movable contact 44a, 48a and 49a and fixed contact therefor 44b, 48b and 49b and raising speed and reduce-speed sign.More specifically, under control gear 51 effects, according to the position of speed change lever 7, control mode changes between automatic shift mode and manual shift mode.When speed change lever 7 was positioned at raising speed position 13b, the shelves level was set or changes to carry out the raising speed operation.When speed change lever 7 was positioned at decelerate position 13c, the shelves level was set or changes to carry out deceleration-operation.
A locking cam 52 that is connected in check plate 14 as shown in Figure 1 has the effect of the action of constraint speed change lever 7, and like this, speed change lever 7 only when braking pedal 53 is operated, could move to other position 11b to 11d from P position 11a.Lead 54 is parts that are used for the action of pedal 53 is passed to cam 52.
Next the operation of the speed change gear 5 that constitutes is by this way described.Suppose to be located at the D position 11d of the main switch mouth 11 at transition sluice gate 12 1 end places such as speed change lever 7.In this state, shown in Fig. 2 and 8, speed change lever 7 flexibly remains on D position 11d by stopping device 20.At this moment, because stressed and be assemblied in one of recess 43 by the counterpart of releasing from movable part 21 42, the movable part that is used to select 21 that has moved to main switch mouth 11 is maintained at above-mentioned position.When the motion of movable part 21 is restricted by this way, produced a power of fixing this movable part 21.When this retention force was delivered to speed change lever 7 by selecting arm 22b, speed change lever 7 just was fixed on an end place of transition sluice gate 12, promptly in the main switch mouth 11.Suppose the driver along main switch mouth 11 vertically move speed change lever 7 so that select any one to be different from other shift pattern 11a to 11c of D position 11d.In this case, the movable part 21 that is used to select moves never, has only and selects arm 22b slip in the hole 38 of the penetrating component 39 of movable part 21 longitudinally.Like this, if longitudinally handle speed change lever 7, it just moves along sluice gate 11 separately in the vertical, and movable part 21 is motionless.If stop pin 7a is assemblied in in the stop notch 16 at required shift pattern place any one by discharging the release 7c that handles knob, then speed change lever 7 just is maintained at required shift pattern so that implement automatic shift mode.
It is distolateral to suppose that speed change lever 7 moves to another of transition sluice gate 12 from D position 11d, promptly arrives the neutral position 13a of manual sluice gate 13, so that automatic shift mode is changed to manual shift mode.In this case, the movable part that is used to select 21 moves along the direction identical with speed change lever 7, shown in Fig. 3,11,14B and 14D.Like this, when speed change lever 7 was operated with above-mentioned direction, the lateral margin of selection arm 22 matched with the internal face 38a in the hole 38 on movable part 21, like this, makes the moving direction pressurized of whole movable part 21 along speed change lever 7.Therefore, the movable part 21 that is used to select slides along the direction identical with the speed change lever direction of operating, promptly enters slid chamber 36.When speed change lever 7 beginning when above-mentioned direction moves, counterpart 42 comes out from the recess 43 on the right-hand side (XR side), moves to the flattened side of slid chamber 36, like this, has just reduced speed change lever 7 to be fixed on the power in the main switch mouth 11 always.
When counterpart 42 left recess 43 by this way, retention force was more much smaller than the power when counterpart 42 is positioned at recess 43.Therefore, when mode transformation operation beginning, can obtain an engaging sensation.When speed change lever 7 when manual sluice gate 13 tilts, shown in Fig. 3 and 11, gear shift arm 22a and speed change lever 7 together around axle 8a, be that the axis that shakes of speed change lever 7 shakes, to tilt towards stopping device 20.Thereby stop pin 7a throws off from stop notch 16.When speed change lever 7 during at neutral position 13a, arm 22a has been ready to be received in that between the jaw 45c and 45d of projection above the stopping device 20.Yet, when speed change lever 7 when manual sluice gate 13 tilts and move to neutral position 13a, gear shift arm 22a is inserted between jaw 45c and the 45d.When speed change lever 7 arrived neutral position 13a, the counterpart 42 of the movable part 21 that is used to select was to the recess 43 of left-hand side (XL side).Thereby returned counterpart 42 in the 41a of hole utilizes the elastic force of pressure spring 41 and is pushed out and is fitted in the recess 43.In the time of in counterpart 42 is engaged in this recess 43, the motion of movable part 21 is restrained, and like this, speed change lever 7 just is maintained at the neutral position 13a in the manual sluice gate 13.As a result, speed change lever 7 transforms to manual shift mode from automatic shift mode, and counterpart 42 has limited the motion of movable part 21, like this, just can feel an engaging sensation when the mode transformation EO.When the slot type conversion was finished, the movable contact 44a of the movable part 21 that is used to select was electrically connected with the fixed contact therefor 44b of slid chamber 36, shown in Figure 14 D.Thereby an expression is sent to shift controller 51 from the signal that automatic shift mode transforms to manual shift mode.
In the example that describes below, the speed change lever 7 that transforms to manual shift mode by aforesaid operations is operated and moves along manual sluice gate 13 from neutral position 13a.Suppose that speed change lever 7 is such as moving towards raising speed position 13b to carry out the raising speed operation.In this case, preceding jaw 45c is with matching with speed change lever 7 proal gear shift arm 22a, shown in Fig. 4 .12 and 13E.Jaw 45C shakes forward around its corresponding axis 46.At this moment, the movable part 21 that is used to select is remained on the position that is used for manual shift mode by counterpart 42.The arm 22b that is used to select is inserted in the hole 38 of movable part 21 with motion (along the gear-change operation direction) longitudinally.Therefore, shown in Figure 12 and 14, when sliding in the hole 38 of arm 22b at movable part 21, allow speed change lever 7 to move along the raising speed direction.Then, just as in the automatic shift mode, speed change lever 7 becomes and is independent of movable part 21, and is movable to the interior raising speed position of manual sluice gate 13.
When speed change lever 7 arrived raising speed position 13b, shown in Figure 12 and 13E, the movable contact 48a that is used for the movable part 45a of gear shift was electrically connected on the fixed contact therefor 48b that is positioned at the bearing 32 on 35 front sides, bar chamber.Therefore, an expression speed change lever 7 detected signal that is converted into raising speed position 13b sends to shift controller 51.Thereby raising speed EO.
Handled with when decelerate position 13c moves when speed change lever 7, the back movable part 45b that is used for gear shift is shaken backward by the arm 22a effect that is used for gear shift.Equally in this case, the arm 22b that is used to select slides in the hole 38 of movable part 21.Therefore, allow speed change lever 7 to move towards decelerate position 13c.When speed change lever 7 arrived decelerate position 13c, the movable contact 49a of movable part 45b contacted with fixed contact therefor 49b, was sent to shift controller 51 thereby an expression speed change lever 7 changes to the detected signal of decelerate position 13c.In response to the detected signal of this expression raising speed or deceleration-operation, control gear 51 has changed the shelves level of automatic transimission.
As mentioned above, the stopping device that is used for the pattern change 20 utilizations of present embodiment have structurally fixed speed change lever 7 with the movable part (link) 21 that speed change lever 7 separates.According to this structure, when speed change lever 7 during conversion, can obtain an engaging sensation, and speed change lever 7 itself need not have any fixed mechanism between automatic shift mode and manual shift mode.The fixed function that can keep simultaneously, speed change lever 7.Like this, the structure of speed change lever 7 can be simplified, and the reliability of speed change lever 7 can be correspondingly improved.And the movable part that is used to select 21 that has produced retention force never can be followed the motion of speed change lever 7 when speed change lever 7 longitudinally moves in the first or the 3rd sluice gate 11 or 13.Therefore, handling speed change lever 7 so that during in the longitudinal movement of automatic or manual shift mode lower edge, speed change lever 7 can not be subjected to any by the load that produces of weight separately such as movable part 21, counterpart 42, contact plate 44c.Therefore, can reduce to be used for automatically and the steering force of the speed change lever 7 of manual shift mode, so just can improve the controllability of the speed change lever under every kind of pattern.
Especially, in above-mentioned main switch mouth 11 is parallel to each other the speed change gear of arranging 5 with manual sluice gate 13, stopping device 20 comprises the movable part that is used to select 21 with hole 38 (or groove), the arm 22a of speed change lever 7 passes this hole 38, also comprise the arm 22b that is used to select, and movable part 21 is by when moving, speed change lever 7 making arm 22b abut against the inner arm face in hole 38 (or groove) and moving along transition sluice gate 12 in sluice gate 12.Like this, although simple in structure, can realize the stop operation that reliability is high.
The sluice gate 13 that is used for manual shift mode has neutral position 13a, and it is corresponding to the other end of transition sluice gate 12, also has respectively first and second shift pattern 13b and the 13c in neutral position 13a front and back.Simultaneously, the speed change lever 7 that longitudinally moves in manual sluice gate 13 utilizes the neutral gear fixed mechanism 23 (second fixing device) on the base plate 6 and is maintained at neutral position 13a.Like this, when speed change lever 7 was not worked in sluice gate 13, it never can return less than neutral position, like this, had just improved the controllability at the speed change lever 7 of manual shift mode.
Neutral gear fixed mechanism 23 comprises that the movable part 45a and the 45b that are used for gear shift are used separately as first and second pushing devices.The first movable part 45a promotes speed change lever 7 by abutting against the speed change lever 7 between neutral position 13a and raising speed position 13b towards neutral position 1 3a.The second movable part 45b promotes speed change lever 7 by abutting against being positioned at the speed change lever 7 between neutral position 13a and the decelerate position 13c towards neutral position 13a.According to this structure, can reduce along the moment of inertia of the speed change lever 7 of manual sluice gate 13 operations.Like this, can reduce to operate the required power of speed change lever 7, and speed change lever 7 can be returned to the neutral position under manual shift mode.
Include the above-mentioned movable part that is used to select 21 in the main body of stopping device 20, be used for movable part 45a and 45b, fixed mechanism 40, neutral gear fixed mechanism 23, mode transformation system 24 and the gear shift shifting mechanism 25 of gear shift.Therefore, be used for the selection operation of speed change lever 7 and the various required function of variable speed operation and concentrate on single main body 33.The stopping device 20 that utilization is arranged in such a way only will install 20 and combine with speed change lever 7 and just can obtain the selection operation of speed change lever 7 and the required function of gear-change operation.In addition, device 20 can be used for the advantage of dissimilar gearshift 5 in addition.And because device 20 can only be connected on the automobile by being fixed to base plate 6, gearshift 5 can be installed and replace easily.Especially, because mode transformation system 24 and gear shift transformation system 25 all are contained in the stopping device 20, during the attended operation of device 20, cannot damage any switch.
Figure 15 has shown the second embodiment of the present invention.According to last embodiment, adopt the switch such as sensitive switch to replace above-mentioned movable contact and fixed contact therefor.These switches are used for sending the mode detection signal that is used for automatic shift mode and manual shift mode, also send raising speed signal and reduce-speed sign.More specifically, a sensitive switch that is used to select 60 utilizes a carriage 60a and is installed in the outer surface of housing 30, and is used for replacing the above-mentioned movable contact and the fixed contact therefor of output mode detected signal.Switch 60 detects an end or the other end that speed change lever 7 moves to transition sluice gate 12 by activateding when the motion of the movable part 21 arrow XL that are used to select or XR direction.A pair of sensitive switch 62a and the 62b that is used for gear shift is arranged on the outer surface of housing 30.When the neutral position 13a of speed change lever 7 in manual sluice gate 13 moved to raising speed position 13b or decelerate position 13c, these switches 62a and 62b were switched on or disconnect.The actuator separately 61 of switch 62a and 62b one corresponding to jaw 45c and 45d between any side of a position of clearance t, i.e. front side or rear side.This layout has guaranteed to have same effect with first embodiment.
Figure 16 has shown the third embodiment of the present invention.According to this embodiment, the movable part 21 that is used to select is designed to directly be taken to when contacting with speed change lever 7 and can slide on the arrow directions X when its part.More specifically, L shaped movable part 21 comprises that one is inserted in the slid chamber 36 with the first arm 65a and that moves from the first arm 65a along sluice gate 11 with the 13 second arm 65b that extend towards speed change lever 7 on the arrow directions X.The second arm 65b has one along sluice gate 11 and 13 slits 66 that extend.Speed change lever 7 passes slit 66.When speed change lever 7 moved on the arrow directions X in transition sluice gate 12, its outer circumferential face abutted against the inner peripheral surface of slit 66.Therefore, the first arm 65a of movable part 21 moves on the arrow directions X along sluice gate 12.Equally, utilize the movable part that is used to select 21 that determines shape by this way, can produce the effect same with first embodiment.
Figure 17,18 and 19 has shown the 4th enforcement of the present invention.According to this embodiment, a module switch (slide switch) is used for replacement activity contact and fixed contact therefor.The movable part 21 that is used to select has a downward perforate 21b at its close end 21a.At slid chamber's 36 downsides one module switch 67 is arranged.As shown in figure 18, switch 67 has a container 68.Fixed contact member 70a, 70b and 70c are arranged at the end 69 of container 68.Contact element 72 has a contact assembling set 71.One contact element that shakes 72 can joltily be supported by assembling set 71.Fixed component 70a is an open usually fixed contact member, and fixed component 70c is a fixed contact member of sealing usually.
Shaking contact element 72 has the contour shape of V-arrangement roughly, and like this, its neutral position N1 that departs from the position that it is supported by contact assembling set 71 slightly is depressed.Bead 75 is being pressed the V-arrangement surface of contact element from above.At operation piece 73 along a side of its movement direction and container towards a pressure spring 77 is arranged between the side arm of operation piece 73.Spring 77 promotes operation piece 73 always towards neutral position N1.When speed change lever 7 was positioned at automatic shift mode, operation piece 73 remained on neutral position N1 by the elastic force of pressure spring 77.When operation piece 73 was positioned at position N1, an end that shakes contact element 70a abutted against common sealed up fixed contact therefor 70c, did not have electrical conduction thereby make fixed contact member 70a and shake contact element 72.When speed change lever 7 when automatic shift mode transforms to manual shift mode, shown in double dot dash line among Figure 18, the movable part 21 that is used to select moves to the left side in the slid chamber 36.In this case, the wall surface of opening 21b cooperates with operation piece 73, and like this, operation piece 73 just slides into left hand position L (being shown among Figure 19), the elastic force of resisting pressure spring 19.Therefore, shake contact element 72 and move to the left side, promote by bead 75.When the other end of contact element 72 contacted open usually fixed contact member 70a, member 72 and 70a were electrically connected mutually.The automatic or manual shift mode of speed change lever 7 can be according to from the connection signal of module switch 67 or throw off signal and measured.
