At the central portion of tabular surface 22a, through the abutting part 21 that is welded with cylindrical shape.Abutting part 21 is provided with along central shaft X, has specified length L1 (for example 3mm).
Abutting part 21 runs through the length direction total length and has same diameter (for example 0.5 φ), and its front end face 21a is the same with above-mentioned tabular surface 22a, becomes the tabular surface with central shaft X quadrature.
In this embodiment, this front end face 21a becomes the bearing surface with the direct butt of overlap when overlap intensity is estimated.
At this, in the overlap evaluating apparatus 1 of embodiment, become the structure of pushing overlap with abutting part 21, abutting part 21 need have when pushing not the hardness of regulation that can bending at least.Under the situation of formation abutting parts 21 such as the cut of passing through axial region 22, have hardness in order to make abutting part 21, need to quench, therefore make cost of manufacture rise.With abutting part 21 during,, just need axial region 22 all not constituted high rigidity as long as abutting part 21 has the hardness of regulation at least with axial region 22 splits design.
In addition, when this abutting part 21 being installed in the front end of axial region 22, do not need aforesaid quenching through welding.Therefore, can suitably prevent the rising of cost of manufacture.
The roughly total length that axial region 22 runs through length direction forms (with reference to Fig. 1 (a)) with same diameter.Shown in Fig. 3 (a), the outer peripheral face in the base end part 22b of axial region 22 side is provided with external thread 22c.
Bear an end of axial region 22 sides of portion 23 at plunger; Be provided with the boss portion 231 of bearing portion's 23 paths than plunger; In the central authorities of this boss portion 231, connect boss portion 231 and bear the half-way of portion 23 and be formed with threaded hole up to plunger, this threaded hole is formed with internal thread 23a in interior week.
Therefore, the base end part 22b side of axial region 22 is born portion 23 to binding so that external thread 22c is screwed into state and the plunger of internal thread 23a.
Plunger bears portion 23 and has cylindrical shape, and shown in Fig. 4 (a), its D outer diameter 7 is littler than the inside diameter D 4 of the through hole on the plunger installation portion 13 14.
Thus, plunger installation portion 13 can be in through hole 14 moving axially along central shaft X.
Shown in Fig. 3 (a), plunger bears in the portion 23, and the outer peripheral face of central portion in the longitudinal direction is formed with the chimeric groove 232 of ball 30b of bulb stopper 30, and this groove 232 formed around circumferentially the spreading all over full week of central shaft X.
In this threaded hole, be screwed with bolt B, bear the other end of portion 23, be fixed with limiter 24 via bolt B at plunger.
Fig. 4 (b) is the B-B sectional view among Fig. 3 (a), (c) is the figure of the part of the limiter 24 in the only expression (b), is the figure that limiter 24 is described respectively.
Shown in Fig. 3 and Fig. 4 (c), the D outer diameter 8 of limiter 24 is identical with the external diameter of limiter 24 sides of plunger installation portion 13, from central shaft X axially and plunger installation portion 13 butts and stop up the opening of through hole 14.
At the central portion of limiter 24, connect limiter 24 and be provided with and make bolt B insert logical bolt hole 24a along thickness direction.
Plunger at limiter 24 bears on the face of portion's 23 sides, is provided with the recess 24b (with reference to Fig. 4 (b), (c)) of inside diameter D 7 that bears the external diameter coupling of portion 23 with plunger with the mode of surrounding bolt hole 24a.In addition, bearing on the face of portion's 23 opposition sides of limiter 24, be provided with the recess 24c (with reference to Fig. 3 (a)) of the internal diameter of the head that can take in bolt B with the mode of surrounding bolt hole 24a with plunger.This recess 24c forms with the degree of depth of the head B1 that can take in bolt B.
In limiter 24, the position at the radial outside of bolt hole 24a is provided with the pin insertion hole 24d that is used to insert spline pin 25 to plunger with bearing portion's 23 side openings.In addition, with the position of this pin insertion hole 24d coupling, to being provided with through hole 24e than pin insertion hole 24d path with plunger with bearing portion's 23 opposition side openings.
The degree of depth h2 of pin insertion hole 24d forms with the axial length L 2 short length than spline pin 25.Therefore, when spline pin 25 was inserted into pin insertion hole 24d, an end of spline pin 25 was more outstanding than the face of plunger installation portion 13 sides.
In this embodiment; Spindle unit 20 is inserted main part 10 from plunger installation portion 13 sides; When the ball 30b of bulb stopper 30 was arranged on and bears the chimeric position (with reference to Fig. 3 (a)) of the groove 232 of portion 23 with plunger, 25 of spline pins were inserted into the otch 13b of plunger installation portion 13.
Under this state, be inserted into the otch 13b of main part 10 at the limiter of spindle unit 20 24 outstanding spline pins 25, therefore, spindle unit 20 is set up with the state with respect to main part 10 splines.
In addition, spindle unit 20 (abutting part 21, axial region 22, plunger bear portion 23, limiter 24, bolt B) is disposed on the central shaft X through the spline pin 25 that is inserted into otch 13b.Therefore, in the scope that is positioned at through hole 14 of spindle unit 20, just the ball 30b of bulb stopper 30 contacts with lining 15 on spindle unit 20.
Therefore, spindle unit 20 is limiting to the acting force of axial mobile quilt from bulb stopper 30, and having in effect on the spindle unit 20 under situation about circumferentially moving, serves as main acting on the sliding resistance with lining 15 from the big power of the acting force of bulb stopper 30 recently.
Action to overlap evaluating apparatus 1 describes.
Fig. 5 is the figure that the evaluation to the overlap T of the cross part that is in oilhole A and oilhole B describes; (a) be the figure that the state before the evaluation of overlap is described; (b) being the figure that the evaluation according to overlap describes to axially movable situation spindle unit 20, (c) is the figure that the situation of overlap T bending is described according to the evaluation of overlap.
At first, shown in Fig. 5 (a), from the direction of intersecting with overlap T with the abutting part 21 of spindle unit 20 to overlap T near, shown in dummy line among the figure, make abutting part 21 and overlap T butt.
Make overlap evaluating apparatus 1 when the direction of pushing overlap T with abutting part 21 moves from this state, effect is from the counter-force of overlap T on spindle unit 20, and the power that the spindle unit direction that arrow F2 representes in figure is moved works.
Shown in Fig. 5 (b), overlap T has when not coming off dangerous enough intensity, though overlap T receive that abutting part 21 pushes can bending yet.Like this; Have corresponding to the counter-force F2 that acts on the pressing force of overlap T from abutting part 21 because on spindle unit 20, act on; So than the big moment of directed force F 1 that is input to spindle unit 20 from bulb stopper 30, ball 30b is brought to and breaks away from groove 232 to leaving direction that plunger bears portion 23 at this counter-force F2.
Thus, the integral body of spindle unit 20 moves to the direction of leaving overlap T, and the spline pin of limiter 24 25 breaks away from the otch 13b of plunger installation portions 13, becomes the state that plunger bears portion 23 and the face butt of the downside of through hole 14.
That is, have at overlap T under the situation of the dangerous enough intensity that do not come off, spindle unit 20 is to moving axially, and limiter 24 comes off from the plunger installation portion of main part 10.Utilizing moving of this spindle unit 20 can grasp overlap T is the dangerous overlap that do not come off.
On the other hand, shown in Fig. 5 (c), when overlap T does not have enough intensity, overlap T bending when receiving abutting part 21 and push.
In this case, in the moment of overlap T bending, abutting part 21 disappears from the counter-force F2 that overlap T bears.In addition, because big unlike the directed force F 1 from bulb stopper 30 from the counter-force F2 of overlap T, therefore, spindle unit 20 is maintained at the initial position shown in Fig. 5 (c).
Therefore, because through overlap T bending, abutting part 21 disappears from the counter-force F2 that overlap T bears, spindle unit 20 can not move, and therefore, can be judged to be overlap T is that the dangerous overlap that comes off is arranged.
Whether like this, spindle unit 20 bears from the counter-force F2 of overlap T and to moving axially, come off from the plunger installation portion 13 of main part 10 based on the limiter of spindle unit 20 24, even whether residual also can the difference simply is good overlap.
As previously discussed, a kind of overlap evaluating apparatus that the intensity of the overlap in the oil circuit that is formed at automatic transmission is estimated is provided in this embodiment, it possesses: cylindrical main body portion 10; Spindle unit 20, it is by main part 10 supporting and can move vertically, and makes distolateral being positioned at outside the main part 10 that has with the abutting part 21 of overlap butt; Bulb stopper 30; It applies the acting force (500gf) of regulation to spindle unit 20; The counter-force of bearing from overlap when pushing overlap through abutting part 21 with opposing; Bulb stopper 30 is radially connecting main part 10 and be provided with in the direction of the acting force that spindle unit 20 is applied regulation from spindle unit 20; Spindle unit 20 is set at following formation, that is: so that when the direction of leaving overlap (axially) moved, another distolateral modes of then giving prominence to from main part 10 that are positioned at main part 10 were provided with than the acting force of stipulating is big when the counter-force of bearing from overlap.
According to this formation, when the counter-force that the acting force of regulation bears from overlap when pushing overlap was big, spindle unit 20 was held in original position.And when the counter-force of bearing from overlap was bigger than the acting force of regulation, spindle unit 20 bore from the counter-force of overlap and moves to another distolateral (leaving the direction of overlap).
Therefore, under the intensity of overlap enough and not came off dangerous situation, the pressing force that abutting part 21 is pushed overlap became big, surpassed moment of the acting force of regulation in the counter-force of bearing from overlap, and spindle unit 20 moves to the direction of leaving overlap.On the other hand, under the not high situation of the intensity of overlap, because will bending when the overlap midway of pushing overlap through abutting part 21, therefore, spindle unit 20 can not move to the direction of leaving overlap.Thus, whether to moving axially, just can judge whether be that the dangerous overlap that comes off is arranged based on spindle unit 20.In addition, at this moment, can not produce fragment that can become snotter etc.
In addition, constitute, the periphery of bearing portion 23 at the plunger of the spindle unit that is positioned at main part 10 20 is provided with the chimeric groove 232 of ball 30b of bulb stopper 30.
According to this formation, through ball 30b axial the moving of axes parts 20 reliably of bulb stopper 30.
At one of main part 10 distolateral reducing diameter part 11; Spindle unit 20 is supported vertically movably; At the other end of spindle unit 20, to be provided with from axially and the other end butt of main part 10 and stop up the limiter 24 of the other end side opening of main part 10 with main part 10 identical D outer diameter 8, spindle unit 20 is set at following formation; That is: make from limiter 24 and engage with the otch 13b of main part 10, be supported by the state of main part 10 with spline to main part 10 side-prominent spline pins 25 (projection).
According to this formation,, therefore, can make the pressing force that acts on overlap even owing to can prevent that when pushing overlap spindle unit 20 from rotating through abutting part 21.
In addition, when spindle unit 20 moved to the direction of leaving overlap, limiter 24 came off from main part 10, therefore, can grasp spindle unit 20 ground reliably and move.
In addition, be set at following formation, that is: at one of main part 10 distolateral reducing diameter part 11, spindle unit 20 is supported via the lining 15 of nylon system vertically movably.
In the embodiment, because main part 10 and spindle unit 20 be made up of stainless steel, therefore, if lining 15 is not set, then when spindle unit 20 moves vertically, the metal of the same race sliding resistance that produces of sliding each other becomes big.So, can not the plunger that the counter-force of bearing from overlap suitably is sent to bulb stopper 30 butts be born portion's 23 sides, the overlap evaluation precision reduces.When the lining 15 of the nylon system of being provided with, because therefore the resistance force diminishes of when spindle unit 20 moves vertically, bearing, improves the overlap evaluation precision.
Abutting part 21 is set at following formation; That is: has an identical cylindrical shape of total length L diameter that runs through length direction; In the front of spindle unit 20, be provided with the tabular surface 22a with the axial quadrature of spindle unit, abutting part is fixed in the central authorities of tabular surface 22a through welding.
Through abutting part 21 being made as other parts, thereby, when wearing and tearing take place abutting part 21, only change abutting part and get final product.In addition, form under the situation of abutting part, need processing such as quenchings grade in order to ensure the intensity of abutting part 21 through the front end at spindle unit 20 such as cut.Relative with it, abutting part 21 is made as other parts and through welding fixedly the time, it is cheap that cost of manufacture becomes.
Then, the overlap evaluating apparatus 1A to second embodiment describes.
Among the overlap evaluating apparatus 1A of second embodiment, thereby use spring S to replace the ball match 30 of the 1st embodiment to limit spindle unit 20 axial moving.
Therefore, spindle unit 20 bears portion 23 at the spring abutting part 23A that the base end part 22b of axial region 22 possesses cylindrical shape to replace above-mentioned plunger.
This spring abutting part 23A forms with the through hole 14 little diameters than main part 10, in through hole 14, can move vertically.
And, the end of spring S is arranged at the face butt with axial region 22 opposition sides of spring abutting part 23A.
At main part 10 and end 10a reducing diameter part 11 opposition sides, acting force governor motion 50 is screwed into and is installed on through hole 14.
Acting force governor motion 50 possesses: flange part 52, adjusting screw 53 that periphery is formed with the axial region 51 of external thread 51a, extends to radial outside from the cardinal extremity of axial region 51.
Axial region 51 has the external diameter with the internal diameter of through hole 14 coupling, makes the external thread 51a of periphery be screwed into the internal thread 10b of main part 10 and be fixed in main part 10.
At axial region 51, be provided with spring installation portion 511 than axial region 51 paths at the front end of spindle unit 20 sides.Spring installation portion 511 has cylindrical shape, and the other end of spring S is installed to embedding outside its periphery.
At axial region 51,, run through being provided with the flange part 52 that extends to radial outside full week at the outer peripheral face of the cardinal extremity of the outside that is positioned at main part 10.
Adjusting screw 53 is overlooked to having annular shape, and centre portion is provided with and makes axial region 51 insert logical opening 53a therein.Inner peripheral surface at opening 53a is provided with internal thread (not shown).Therefore, adjusting screw 53 is screwed into and is installed on the periphery of axial region 51, and under this state, adjusting screw 53 can moving axially along central shaft X.
In this embodiment; Through regulating the distance L x of adjusting screw 53 and flange part 52; Can regulate the length L y of the axial region 51 that is positioned at main part 10,, change the axial length L z of spring S through changing the length L y of this axial region 51; Thereby, can regulate the acting force that acts on spindle unit 20 from spring S.
In this embodiment, with the situation of the 1st embodiment likewise, with acting force the mode of spindle unit 20 left side (abutting part 21 leaves the direction of main part 10) application of force in figure is regulated each length L x, Ly, Lz with 500gf.

Fig. 7 is the figure that the evaluation to the overlap T of the cross part that is in oilhole A and oilhole B describes; (a) being the figure that the evaluation according to overlap describes to axially movable situation spindle unit 20, (b) is the figure that the situation of overlap bending is described according to the evaluation of overlap.
Shown in Fig. 7 (a), with the abutting part 21 of spindle unit 20 from the direction of intersecting with overlap T to overlap T near, make abutting part 21 and overlap T butt.
Make overlap evaluating apparatus 1A when the direction of utilizing abutting part 21 to push overlap T moves from this state, effect has the counter-force from overlap T on spindle unit 20, and the power that the spindle unit direction that arrow F2 representes in figure is moved works.
Spring S is connected to the spring abutting part 23A of spindle unit 20, and the direction that arrow F1 representes in figure has limited spindle unit 20 axial moving to spindle unit 20 application of forces.
When overlap T has the sufficient intensity that does not come off dangerous, even pushed by abutting part 21 can bending yet for overlap T.So; Because effect is corresponding to the counter-force F2 that acts on the pressing force of overlap T from abutting part 21 on spindle unit 20, therefore, at this counter-force F2 than the big moment of directed force F 1 that is input to spindle unit 20 from spring S; Spring S is compressed (in the situation of Fig. 7, being compressed to Lz ' from Lz).
Thus, axial region 22 moves to figure right-of-center in political views direction, and the mark Mk of the periphery of axial region 22 is hidden in the reducing diameter part 11 of main part 10 and becomes and cannot see.
That is, have at overlap T under the situation of the dangerous sufficient intensity that do not come off, because spindle unit 20 is to moving axially; Mark Mk is hidden in the reducing diameter part 11 of main part 10 and becomes and cannot see; Therefore, Mk cannot see according to mark, and can grasp overlap T is the dangerous overlap that do not come off.
On the other hand, when overlap T does not have enough intensity, shown in Fig. 7 (b), then bending when overlap T is pushed by abutting part 21.
In this case, because bigger from the counter-force F2 that overlap T bears than abutting part 21 from the directed force F 1 of spring S, therefore, spindle unit 20 can be to moving axially.Therefore, the mark Mk of the periphery of axial region 22 can not be hidden in the reducing diameter part 11 of main part 10 and becomes and cannot see.
In addition, in the moment of overlap T bending, because abutting part 21 disappears from the counter-force F2 that overlap T bears, therefore, according to the situation that its counter-force disappears, also can grasp overlap T is that the dangerous overlap that comes off is arranged.
Like this, in the overlap evaluating apparatus 1A of second embodiment, spindle unit 20 bears from the counter-force of overlap T and to moving axially, based on whether cannot see the mark Mk that is installed on axial region 22, even whether residual also can the difference simply is good overlap.
As previously discussed, a kind of overlap evaluating apparatus that the intensity of the overlap in the oil circuit that is formed at automatic transmission is estimated is provided in second embodiment, it constitutes possesses: cylindrical main body portion 10; Spindle unit 20, it is through main part 10 supporting and can move vertically, and makes distolateral being positioned at outside the main part 10 that has with the abutting part 21 of overlap butt; Spring S; The acting force (500gf) of the regulation that it applies spindle unit 20; The counter-force of bearing from overlap when pushing overlap through abutting part 21 with opposing; Spring S is radially being arranged in the main part 10 in the direction of the acting force of regulation applying spindle unit 20 from spindle unit 20; In the periphery of the spindle unit 20 of the outside that is positioned at main part 10, bigger and make spindle unit 20 when axially (direction to leaving overlap moves) moves than the acting force of regulation in the counter-force of bearing from overlap, invisible position is provided with mark Mk in the reducing diameter part that is hidden in main part 10 11.
According to this formation, when the counter-force of bearing from overlap when pushing overlap at the acting force of regulation was big, spindle unit 20 was held in the origin-location.And when the counter-force of bearing from overlap was bigger than the acting force of stipulating, spindle unit 20 bore from the counter-force of overlap and to another distolateral (leaving the direction of overlap) and moves, and the mark Mk of spindle unit 20 becomes and cannot see.
Therefore; Under the intensity of overlap enough and not came off dangerous situation, the pressing force that abutting part 21 is pushed overlap became big, surpasses the moment of the acting force of regulation in the counter-force of bearing from overlap; Spindle unit 20 moves to the direction of leaving overlap, and mark Mk becomes and cannot see.On the other hand, under the not high situation of the intensity of overlap, because the overlap midway of pushing overlap at abutting part 21 is with regard to bending, therefore, spindle unit 20 can not move to the direction of leaving overlap.Therefore, mark Mk still can see.Thus, whether cannot see, can judge whether be that the dangerous overlap that comes off is arranged based on the mark of spindle unit 20.In addition, at this moment, can generation can not become fragment of snotter etc. yet.
