Like Fig. 1 and shown in Figure 2, the gear lever apparatus of this example (CLU:Change Lever Unit) 1 comprises: as the container-like device body 2 of sensor structure formation; Be installed on the housing 3 of the upper end of device body 2 dismantledly, with the open upper end of inaccessible this device body 2.
In device body 2, gear shift turning cylinder 4 is provided with around its central axis rotationally.In addition, run through to be provided with a choosing shelves turning cylinder 5 at this gear shift turning cylinder 4, vertical with gear shift turning cylinder 4.Further, an end of shifter bar 6 is rotatably installed on this choosing shelves turning cylinder 5.So shifter bar 6 can rotate for the center by gear shift turning cylinder 4, and can select grade turning cylinder 5 to rotate for the center.
Be provided with form and gear shift layout hole 7 that shifter bar 6 run through corresponding with the gear shift layout of the CLU1 of this example in the upper end of housing 3.The path that this shifter bar 6 passed through when this gear shift layout hole 7 was shifter bar 6 quilt operations.Shown in Fig. 3 (A), the gear shift layout 8 of this example has the first gear shift row Si1 that separates predetermined space configuration parallel to each other and the second gear shift row Si2,1 choosing shelves row Se.In this case, first and second gear shift row Si1, Si2 and choosing shelves row Se are orthogonal.
At the first gear shift row Si1,3 gears of Parking (P), neutral gear (N) and reversing (R) are configured to row successively from the top in Fig. 3 (A).In addition, at the second gear shift row Si2, upgrade (UP), 3 gears that drive (D) and lower category (DOWN) are configured to row successively from the top in Fig. 3 (A).Further, at a choosing shelves row Se, neutral gear (N), drive 3 gears that (D) and automanual switch (A/M) in Fig. 3 (A) from the right-hand row that are configured to successively.In addition, the N gear of the first gear shift row Si1 is identical with the N gear of choosing shelves row Se, and in addition, the D gear of the second gear shift row Si2 is also identical with the D gear of choosing shelves row Se.And gear shift layout hole 7 forms and these first and second gear shift row Si1, Si2 and choosing shelves row Se corresponding shape.
Like Fig. 1 and shown in Figure 2, at gear shift turning cylinder 4, Parking bar 9 and shifter bar 6 adjacent setting.Shown in Fig. 4 (A) to (C), this Parking bar 9 forms substantially planar.In this case, Parking bar 9 has the first arm 9a and the second arm 9b, and first and second arm 9a, 9b are orthogonal, form roughly L shaped.Parking bar 9 has the circular port 9c that is arranged in roughly L shaped bight, and runs through this circular port 9c through gear shift turning cylinder 4, is supported by gear shift turning cylinder 4 rotationally.
Vertically be provided with the cable connecting part 9d of the pin shape that the end with Parking cable 10 links at the leading section of the first arm 9a.Though not shown, the other end of Parking cable 10 links with the gear shift lock cell of the change-speed box (TM) that mechanically locks automatic transmission with hydraulic torque converter etc.And through stretching Parking cable 10, the work of gear shift lock cell mechanically locks change-speed box, and it can't be worked.
Be equipped with at the second arm 9b and be stuck hole 9e and lock hole 9f, lock hole 9f is same width than the narrow width that is stuck hole 9e or with being stuck hole 9e.Be stuck hole 9e and lock hole 9f and all form the roughly oblong of extending along the length direction of the second arm 9b.In this case, lock hole 9f compares the front that is positioned at the second arm 9b with being stuck hole 9e, and is stuck hole 9e and forms continuously.
As shown in Figure 1, at shifter bar 6, engaging separative element 11 is installed by mount pin 12, and this engaging separative element 11 moves with shifter bar 6 integratedly.Engaging separative element 11 has engagement section 11a, and this engagement section 11a is bent into approximate right angle and outstanding the setting towards Parking bar 9.And when shifter bar 6 was positioned at the first gear shift row Si1 shown in the solid line of Fig. 1, the engagement section 11a of engaging separative element 11 ran through being stuck in the 9e of hole of Parking bar 9.In view of the above, shifter bar 6 engages along the rotation direction around gear shift turning cylinder 4 with Parking bar 9.That is, Parking bar 9 can rotate with respect to the rotation and the shifter bar 6 of the above-mentioned rotation direction of shifter bar 6 integratedly.
In addition, when shifter bar 6 was positioned at the second gear shift row Si2 shown in the long and two-short dash line of Fig. 1, the engagement section 11a of engaging separative element 11 deviate from from the hole 9e that is stuck of Parking bar 9 fully.In view of the above, shifter bar 6 separates with Parking bar 9, removes shifter bar 6 and the binding of Parking bar 9 in above-mentioned rotation direction.So, Parking bar 9 become not with respect to the rotation of the above-mentioned rotation direction of shifter bar 6 and with shifter bar 6 interlocks.In addition, engagement section 11a needn't necessarily run through and is stuck hole 9e, only gets into to be stuck in the 9e of hole, and shifter bar 6 engages rotationally with Parking bar 9 and gets final product.
As shown in Figure 1, be provided with Parking rod lock unit 13 at the housing 3 of Parking bar 9 sides.This Parking rod lock unit 13 has screw actuator 13a, Lock Part 13b, all the time to the not shown spring of Lock Part 13b effect.Lock Part 13b is set at when shifter bar 6 is set at the D gear, with opposed with the lock hole 9f of the Parking bar 9 of shifter bar 6 unitary rotation.Then, during by excitation, Lock Part 13b overcomes the application force of spring, is set at the non-locked position of shown in the solid line of Fig. 1, deviating from fully from lock hole 9f at screw actuator 13a.At the non-locked position of this Lock Part 13b, Parking bar 9 can rotate.In addition, during not by excitation, Lock Part 13b is because the application force of spring is set at the latched position that shown in the long and two-short dash line of Fig. 1, gets in the lock hole 9f at screw actuator 13a.In the latched position of this Lock Part 13b, Parking bar 9 and the rotation direction engaging of Lock Part 13b at Parking bar 9, Parking bar 9 can't rotate, and Parking bar 9 remains on this position.
In addition, though the not shown gear lever lock cell that in the CLU1 of this example, is provided with when shifter bar 6 is positioned at the P gear, with gear lever lock limiting-members locking shifter bar 6, stops shifter bar 6 to move to other gear; When shifter bar 6 from the P gear when other gear moves, through stepping on brake pedal, remove shifter bar 6 by the locking of gear lever lock limiting-members with the screw actuator excitation, shifter bar 6 can be moved to other gear.This gear lever lock cell and gear lever lock cell with the record of above-mentioned TOHKEMY 2009-292387 communique are that the known in the past gear lever lock cell of representative is identical.And, in the Parking rod lock unit 13 of this example, the screw actuator of the gear lever lock cell that its screw actuator 13a was can dual-purpose known in the past.In view of the above, needn't be provided with special-purpose screw actuator at the screw actuator 13a of Parking rod lock unit 13, increase that can suppression device quantity realizes the miniaturization and of Parking rod lock unit 13.Under the solenoidal situation of screw actuator 13a dual-purpose gear lever lock cell, though the power transfer unit that solenoidal magnetic force is passed to Lock Part 13b uses not shown known in the past power transfer unit.So this power transfer unit is simple designability item, it explains omission.In addition, inferior in the situation of the miniaturization and that does not require Parking rod lock unit 13, also can be provided with special-purpose screw actuator at the screw actuator 13a of Parking rod lock unit 13.
As shown in Figure 1, for reaching, each gear that detects shifter bar 6 respectively selects P PARK Position P, in the CLU1 of this example, be provided with MLP detecting unit 14.This MLP detecting unit 14 has: the magnet 14a that is located at the lower end (device body 2 sides one end of shifter bar 6) of shifter bar 6; The Hall element 14b of can be opposed with magnet 14a and establishing at device body 2.In this case, Hall element 14b is made as the center of its center through choosing shelves turning cylinder 5, and is positioned on the straight line vertical with gear shift turning cylinder 4.And when shifter bar 6 was the position vertical with gear shift turning cylinder 4, the center of the center of magnet 14a and Hall element 14b was opposed.
Next, the control of the Parking rod lock unit 13 of this example is described.Whether the control of the excitation of the screw actuator 13a of Parking rod lock unit 13 is that TCU judges from the selecting the P PARK Position P signal of Hall element 14b input, have the above signal of certain value to input to that TCU carries out.That is, in the CLU1 of this example,, use the operational ton (position of choosing shelves row Se, more specifically be the work angle of choosing shelves direction) of the choosing shelves direction of shifter bar 6 as the parameter of the work of control Parking rod lock unit 13.So, TCU according to the work angle of the choosing shelves direction of shifter bar 6, be position, the excitation of control solenoid 13a and the non-excitation of the choosing shelves row Se of shifter bar 6.
And TCU will select the work angle and the predefined set angle of the shifter bar 6 of shelves direction to compare, and judge excitation and the non-excitation of screw actuator 13a.Particularly, TCU will be that decision content compares from select the P PARK Position P signal and the corresponding preset threshold of set angle of shifter bar 6 of Hall element 14b, judge excitation and the non-excitation of screw actuator 13a.So, select the decision content of P PARK Position P signal to constitute screw actuator excitation permission decision content, this screw actuator excitation permission decision content is set with 2, i.e. first and second decision content (first and second threshold value).And these first and second decision contents separately use according to the direction of operating of shifter bar 6.In addition, the excitation of the screw actuator 13a of Parking rod lock unit 13 control also can be that microcomputer replaces TCU, judges and selects in the P PARK Position P signal above-mentioned, and the microcomputer that whether has the above signal of certain value to input to be loaded in the CLU1 carries out.
Fig. 5 (A) and Fig. 5 (B) are explanations from the first gear shift row side of the shifter bar figure towards the control of the solenoidal excitation of the operation of the choosing shelves direction of the second gear shift row side and non-excitation; Fig. 6 (A) and Fig. 6 (B) are explanations from the second gear shift row side of the shifter bar figure towards the control of the solenoidal excitation of the operation of the choosing shelves direction of the first gear shift row side and non-excitation.
First and second decision content of screw actuator excitation permission decision content at first, is described.Shown in Fig. 5 (A) and Fig. 6 (A); Shifter bar 6 is being reference position C with gear shift turning cylinder 4 vertical positions; If shifter bar 6 from the work angle of the shifter bar 6 of reference position C under the situation that the first gear shift row Si1 direction is rotated for just; In addition, establish shifter bar 6 from the work angle of the shifter bar 6 of reference position C under the situation that the second gear shift row Si2 direction is rotated for negative.When shifter bar 6 was positioned at reference position C, the center of the center of magnet 14a and Hall element 14b was opposed.In view of the above, reference position C utilizes MLP detecting unit 14 to carry out the bench mark of the position probing of shifter bar 6.
And first decision content is set to that set angle and the θ 1 (for example+5 degree) of shifter bar 6 is cooresponding to select the P PARK Position P signal value from Hall element 14b.This first decision content is corresponding with the position of the shifter bar 6 of following state and set; This state is that the engagement section 11a of engaging separative element 11 begins to deviate from from the hole 9e that is stuck of Parking bar 9; But the part of engagement section 11a still gets into and is stuck in the 9e of hole, but the engagement section 11a and the Parking bar 9 of engaging separative element 11 are fastening state in the rotation direction of Parking bar 9.So first decision content is set the initial value of screw actuator excitation permission decision content when having shifter bar 6 in the excitation zone of screw actuator 13a.Like this, the reason of setting first decision content is, guarantees to prevent that the engagement section 11a that engages separative element 11 from removing preventing property with the engaging that engaging of Parking bar 9 removed, and, because shifter bar 6 is set at P gear or N gear under most of situation when it starts.
In addition, second decision content is set to that set angle and the θ 2 (for example-1 degree) of shifter bar 6 is cooresponding to select the P PARK Position P signal value from Hall element 14b.This second decision content is corresponding with the position of following shifter bar 6 and set; This position is that the engagement section 11a of engaging separative element 11 finishes to deviate from from the hole 9e that is stuck of Parking bar 9; The engagement section 11a of engaging separative element 11 is in the state that can't engage with Parking bar 9, but shifter bar 6 no show D select P PARK Position P.
Here, explain and shown in Fig. 5 (B), be positioned at shifter bar 6 that N selects P PARK Position P selects the operated situation of direction from P PARK Position P to D.In this case, when shifter bar 6 was positioned at N and selects P PARK Position P, what the engagement section 11a of engaging separative element 11 got into Parking bar 9 was stuck hole 9e, but engaging separative element 11 is in fastening state with Parking bar 9.In addition, screw actuator 13a is by excitation, and Lock Part 13b deviates from from lock hole 9f, is in the state that can't engage with Parking bar 9.Further, screw actuator excitation permission this moment decision content is set to first decision content.
If shifter bar 6 selects P PARK Position P to select P PARK Position P in the direction operation of choosing shelves and through set angle θ 1 to D from N, then shifter bar 6 gets into the non-excitation of screw actuator zone.But after shifter bar 6 got into the non-excitation of screw actuators zone, the engagement section 11a of engaging separative element 11 did not deviate from from the hole 9e that is stuck of Parking bar 9 fully, and was in the state that engaging separative element 11 and Parking bar 9 still can engage.Shifter bar 6 can carry out non-excitation to screw actuator 13a through getting into the non-excitation of screw actuator zone, and TCU removes the excitation of screw actuator 13a.Because screw actuator 13a becomes non-excitation, Lock Part 13b is because in the lock hole 9f of the application force entering Parking bar 9 of spring.In this case, because lock hole 9f is in the opposed position with Lock Part 13b, so Lock Part 13b stably gets in the lock hole 9f.In view of the above, Parking bar 9 is locked and is maintained at its position.Then, shifter bar 6 selects P PARK Position P through moving to D, and the engagement section 11a of engaging separative element 11 deviates from from the hole 9e that is stuck of Parking bar 9 fully.In view of the above, shifter bar 6 separates with Parking bar 9, removes shifter bar 6 and Parking bar 9 engaging in rotation direction.Consequently, shifter bar 6 can rotate with Parking bar 9 free of one anotherly.Even Parking bar 9 is in freedom with respect to shifter bar 6, because Lock Part 13b gets into lock hole 9f and lock Parking bar 9, so Parking bar 9 can't rotate, and shifter bar 6 is maintained at the turned position when being set in the D gear.So the hole 9e that is stuck of Parking bar 9 is maintained at and the engagement section 11a opposed position that engages separative element 11.In addition, if shifter bar 6 passes through set angle θ 2, then screw actuator excitation permission decision content is switched to second decision content.
Next, explain and shown in Fig. 6 (B), be positioned at shifter bar 6 that D selects P PARK Position P selects the operated situation of direction from P PARK Position P to N.In this case, when shifter bar 6 was positioned at D and selects P PARK Position P, the engagement section 11a of engaging separative element 11 deviate from from the hole 9e that is stuck of Parking bar 9, and engaging separative element 11 is in Parking bar 9 can't fastening state.In addition, screw actuator 13a becomes non-excitation, and Lock Part 13b gets in the lock hole 9f, is in the state that engages rotationally with Parking bar 9.Further, screw actuator excitation permission this moment decision content is set to second decision content.
If shifter bar 6 selects P PARK Position P to select P PARK Position P selecting a shelves direction to be operated and passing through set angle θ 2 to N from D, then shifter bar 6 gets into screw actuator excitation zone.But after shifter bar 6 got into screw actuator excitation zone, the part of the engagement section 11a of engaging separative element 11 got into being stuck in the 9e of hole of Parking bar 9, and engaging separative element 11 is in the state that engages rotationally with Parking bar 9.In this case, because the hole 9e that is stuck of Parking bar 9 is maintained at and engagement section 11a opposed position, stable also the entering swimmingly of the engagement section 11a that therefore engages separative element 11 is stuck in the 9e of hole.In addition, because shifter bar 6 passes through set angle θ 1, screw actuator excitation permission decision content is switched to first decision content.Because screw actuator excitation permission decision content is switched to first decision content, can carry out excitation to screw actuator 13a, TCU is with screw actuator 13a excitation.Because screw actuator 13a is by excitation, Lock Part 13b overcomes the application force of spring, deviates from from the lock hole 9f of Parking bar 9.In view of the above, remove the locking of Parking bar 9.Then, shifter bar 6 selects P PARK Position P through shifting into N, and the engagement section 11a of engaging separative element 11 significantly gets into being stuck in the 9e of hole of Parking bar 9, and shifter bar 6 and Parking bar 9 are stuck in rotation direction.Consequently, shifter bar 6 can rotate with Parking bar 9 integratedly.In addition, if shifter bar 6 passes through set angle θ 1, then screw actuator excitation permission decision content is switched to first decision content.
Like this; In the CLU1 of this example; Utilize the state that engage separative element 11 engagings and Parking bar 9 to utilize under the state of the state that Parking rod lock unit 13 locks maintaining shifter bar 6 and Parking bar 9, carry out the engaging of shifter bar 6 and Parking bar 9 and separate.
Next, the work of the CLU1 of this example is described.

In order to make vehicle launch, if shifter bar 6 is operated to the direction of D gear in choosing shelves direction from the N gear, then screw actuator 13a is in non-excitation, and Lock Part 13b is in latched position.In view of the above, the rotation of locking Parking bar 9, Parking bar 9 is maintained at its turned position.In addition, the engagement section 11a of engaging separative element 11 deviates from from the hole 9e that is stuck of Parking bar 9, and shifter bar 6 rotates with Parking bar 9 free of one anotherly.In view of the above, the operation of shifter bar 6 does not influence the mechanical caging unit of change-speed box, can be with good operation sense operation shifter bar 6.Then, shifter bar 6 is through for example being set at the D gear, and vehicle can start.
In order vehicle to be stopped and getting off, if shifter bar 6 is operated to the direction of N gear in a choosing shelves direction from the D gear, the engagement section 11a that then engages separative element 11 gets in the connecting hole 9e of Parking bar 9, and shifter bar 6 and Parking bar 9 engage in rotation direction.In addition, stepping under the situation of brake pedal, screw actuator 13a is by excitation, and Lock Part 13b is in non-locked position.In view of the above, Parking bar 9 can rotate.If shifter bar 6 is in the N gear and further rotates and be set at the P gear along the first gear shift row Si1, then Parking bar 9 also rotates with shifter bar 6 integratedly.Utilize the rotation of this Parking bar 9, the work of gear shift lock cell mechanically locks change-speed box.
According to the CLU1 of this example, promptly during the first gear shift row Si1, utilize engaging separative element 11 at the predetermined gear of having selected to set at least the P gear, Parking bar 9 engages with shifter bar 6.In view of the above, Parking bar 9 can also be worked at the operations linkage of the first gear shift row Si1 with shifter bar 6, can utilize the operation of shifter bar 6 to make the work of gear shift lock cell and lock change-speed box via Parking cable 10.In addition, during the second gear shift row Si2 beyond having selected not set the predetermined gear of P gear, remove shifter bar 6 and utilize the engaging that engages separative element 11 with Parking bar 9, Parking bar 9 is from shifter bar 6 separation.So even shifter bar 6 is operated at the second gear shift row Si2, Parking bar 9 can not worked yet, and can prevent the slip of Parking cable 10.In view of the above, can prevent that Parking cable 10 often slides when operation shifter bar 6, can prevent the towing of Parking cable 10.Consequently, when the second gear shift row Si2 was operated, the operation of shifter bar 6 can not receive the sliding resistance of Parking cable 10, can realize the raising of the operation sense of shifter bar 6, and can realize the raising of the durability of Parking cable 10 at shifter bar 6.
In addition, in the gear shift row beyond the first gear shift row Si1,, therefore can alleviate the restriction of the movable range of Parking cable 10 because Parking cable 10 does not slide.In view of the above, can improve the gear shift layout, be the degree of freedom of the operation mode or the work angle of shifter bar 6.
Further,, can utilize Parking rod lock unit 13 to prevent moving of Parking bar 9, Parking bar 9 is remained on the position when separating having selected the second gear shift row Si2 and Parking bar 9 beyond the predetermined gear when shifter bar 6 separates.In view of the above, when shifter bar 6 engages with Parking bar 9 again, shifter bar 6 is engaged reliably with Parking bar 9.
Further, 13 use under the situation of screw actuator 13a in Parking rod lock unit, through the screw actuator in this screw actuator 13a dual-purpose gear lever lock cell, can not use special-purpose screw actuator.In view of the above,, also can prevent the increase of number of devices, can effectively realize miniaturization and the lightweight of CLU1 simultaneously even be provided with Parking rod lock unit 13.
Further, utilize the state that engage separative element 11 engagings and utilize under the state of the state that Parking rod lock unit 13 locks maintaining shifter bar 6 and Parking bar 9, carry out the engaging of shifter bar 6 and Parking bar 9 and separate with Parking bar 9.In view of the above, the engaging again after the separating of shifter bar 6 and Parking bar 9 can be carried out reliably, and the slip of Parking cable 10 can be suppressed reliably.Particularly, through preestablishing and cooresponding first and second decision content of the work angle of shifter bar 6, can improve the reliability of the work of Parking rod lock unit 13.
In addition, the invention is not restricted to above-mentioned example, can carry out various design modifications.For example, the gear shift layout of CLU1 is between P gear and R gear, to set the N gear in above-mentioned example, but shown in Fig. 3 (B), also can the R gear be set between P gear and the N gear.In addition, the gear shift of gear shift layout row are set at first and second gear shift row Si1, these 2 row of Si2, but the gear shift layout also can be set at the gear shift layout with the above a plurality of gear shift row of 3 row.Further; Parameter as the work of controlling Parking rod lock unit 13; Use the work angle of the choosing shelves direction of shifter bar, but also can use other relevant parameter of operation of operation acceleration/accel etc. and the choosing shelves direction of shifter bar of choosing shelves direction of operating speed or shifter bar of the choosing shelves direction of shifter bar.Importantly, can in the scope of the technology contents that claim is put down in writing, carry out various design modifications.
