As Fig. 1~shown in Figure 4, the valve timing adjustment device 1 of this example 1 roughly comprises: the bent axle (not shown) by chain (not shown) and motor (not shown) is first solid of rotation 1 of rotation synchronously; And be provided in this first solid of rotation 1 and with fixing all-in-one-piece second solid of rotation 3 of the end face of air inlet or exhaust cam shaft (below be called camshaft) 2.
First solid of rotation 1 comprises: have the sprocket wheel 4a of the rotary driving force of accepting bent axle (not shown) in the outside and have in the inboard towards the housing 4 of the outstanding a plurality of crawler shoe 4b of radially inner side; And the protecgulum 5 and the bonnet 6 that seal the inner space of this housing 4, the three utilizes bolt 7 to be fixed into one.
Second solid of rotation 3 is made of rotor 10, and this rotor 10 comprises: across packing ring 8 utilize bolt 9 one be attached on the end face of camshaft 2 protuberance 10a and from the peripheral part of this protuberance 10a towards the outstanding a plurality of blade 10b of radial outside.A plurality of inner spaces that the blade 10b of this rotor 10 will be formed by the crawler shoe 4b of housing 4 are divided into: in a plurality of advance angle hydraulic chamber 11 that makes rotor 10 accept when advance side is rotated relatively that oil pressure supplies with respect to first solid of rotation 1 and in a plurality of retardation angle hydraulic chamber 12 that makes rotor 10 accept with respect to first solid of rotation 1 that oil pressure supplies with when the retardation angle side is rotated relatively.In each advance angle hydraulic chamber, be communicated with supply, the discharging oil pressure advance angle oil circuit 13, in each retardation angle hydraulic chamber, be communicated with supply, the discharging oil pressure retardation angle oil circuit 14.
On the crawler shoe 4b of housing 4, be formed with the reception hole (first hole) 15 that radially connects.Being equipped with from the radial outside insertion in this reception hole 15 can be along this roughly columned stop pin 16 that radially moves back and forth.In addition, on the direction of intersecting with reception hole 15 of crawler shoe 4b (rotor 10 axially), be formed with roughly columned hole (second hole) 4b-1, be inserted in the roughly columned axle 17 that the rear end of the rear end of the helical spring 18 in the described reception hole 15 and stop pin 16 is inserted in the described hole 4b-1 with the form of urge lock pin 16 and block.
Peripheral part at the protuberance 10a of rotor 10 is formed with engaging recessed part 19, when rotor 10 was positioned at maximum retardation angle position with respect to the relative position of housing 4, the front end of described stop pin 16 engaged before radially inner side and then with described engaging recessed part 19 under the application of force of helical spring 18.In addition, on this engaging recessed part 19, be communicated with releasing oil circuit 20.
Below action is described.
At first, when rotor 10 was positioned at Fig. 1~Fig. 3 and Fig. 5, maximum retardation angle position shown in Figure 6 with respect to the relative position of housing 4, stop pin 16 engaged (state is locked and fastened) with engaging recessed part 19 under the application of force of helical spring 18.Under this state, if make stop pin front end 16a pressurized to engaging recessed part 19 supply oil pressure by removing oil circuit 20, then stop pin 16 overcomes the application of force of helical spring 18 and slides towards radial outside in stop pin reception hole 15, is disengaged with engaging of engaging recessed part 19.At this moment, the oil of stop pin back pressure side is discharged from the space that is arranged between stop pin reception hole 15 and the axle 17.As Fig. 7, shown in Figure 8, by in advance angle hydraulic chamber 11, supply with oil via advance angle oil circuit 13, and the oil in the retardation angle hydraulic chamber 12 are discharged via retardation angle oil circuit 14, as shown in Figure 4, the rotor 10 that stop pin 16 has been removed locking relatively rotates towards advance side.
In addition, is the occasion of advance angle position at rotor 10 with respect to the relative position of housing 4, oily by in retardation angle hydraulic chamber 12, supplying with via retardation angle oil circuit 14, and the oil in the advance angle hydraulic chamber 11 are discharged via advance angle oil circuit 13, rotor 10 relatively rotates towards the retardation angle side.If rotor 10 turns to maximum retardation angle position with respect to the relative position of housing 4, then stop pin 16 engages with engaging recessed part 19 sliding towards radially inner side in reception hole 15 under the application of force of helical spring 18.
As mentioned above, adopt this example 1, owing to diameter is approached take in hole and this reception hole of the diameter of stop pin and helical spring reception hole to be formed on the crawler shoe across, and the axle that inserts the substantial cylindrical shape in this hole blocks helical spring flying out, so can make big footpath for the hole of this insertion and also can make of mould, can be with the also disposable formation in hole when forming housing by casting etc.Therefore, need not to carry out hole processing, can cut down fabricating cost by cutting.In addition,, therefore need not cutting because axle can use the parts of the simple shape of substantial cylindrical shape, can be by disposable formation such as castings.Consequently, can cut down fabricating cost, can reduce dimensional accuracy, and can improve processing and assembling.
Example 2.
Fig. 9 is the sectional elevation of the major component of expression example 2, and the diameter of axle 17 constitutes less than the diameter of stop pin reception hole and the diameter of helical spring 18.Adopt this structure, the assembly fixture 21 that can use the U font with the two fork sheet 21a that pass the gap (space) 22 that forms between stop pin reception hole 15 and the axle 17 is towards radial compression helical spring 18.Consequently, can easily axle 17 be inserted among the hole 4b-1 that is provided with vertically, can improve assembling.In addition, after assembling, after having pulled down assembly fixture 21, be arranged on stop pin reception hole 15 and the gap 22 of axle between 17 and can play and be used to make the oil drainage hole that oil discharges to stop pin back pressure side or the effect of oil-discharge trough.
Example 3.
Example as shown, axle 17 for example constitutes D tee section shape in order to have helical spring at least one the plane seat surface 17a of carrying on the axial direction of outer circumferential face, and set each size, with the end face that causes axle 17 arc surface and stop pin in mistake when relative because of axle 17 assembly directions, made the end face of stop pin and the arc surface butt of axle 17 before in stop pin is received into reception hole 15 fully, make the front end of stop pin outstanding from the interior week of housing 4 all the time.Consequently, as shown in figure 11, rotor 10 can't insert towards direction shown in the arrow, and perhaps as shown in figure 10, rotor 10 can't rotate, and therefore can know it is loading error, can prevent the outflow of wrong assembly parts reliably.
On the other hand, when the end face of the D of axle 17 shape planar surface portion 17a and stop pin 16 is relative, this D shape planar surface portion 17a compression helical spring 18 of 17 and make stop pin 16 outstanding from reception hole 15, but because each size was set for before the D shape planar surface portion 17a butt of the end face of stop pin and axle 17 and stop pin 16 can be pushed in the reception hole 15 fully, but therefore regular event.
In addition, because the seat surface of helical spring 18 or screw pin 16 directly push axle 17, therefore the D shape planar surface portion 17a of axle 17 is compensated by the rotation of axle 17 in shaft insertion hole with respect to the meeting of inclination slightly of the glide direction of helical spring 18.
Example 4.
Fig. 8 is the figure of expression example 4, with the protecgulum 5 of the end butt of axle 17 and the either party in the bonnet 6 or both sides' (only being protecgulum 5 among Fig. 8) on be formed with the location indentations 5a that engages with shaft end.Adopting this structure, is the occasion of D tee section shape at axle 17 for example, by in advance location indentations 5a being formed D tee section shape, can prevent the loading error of axle 17, and can prevent to cause axle 17 rotations because of vibration.
Example 5.
Figure 12 is the sectional elevation of the major component of expression example 5, and axle 17 constitutes cylindrical shape, and stop pin 16 constitutes cylindrical shape with the level.The arc surface butt of one end of the seat surface of helical spring 18 and axle 17, the stepped part butt of the other end and stop pin 16 forms around the minor diameter part of stop pin.In addition, the end face of stop pin 16 minor diameter part sides when the stop pin release with the axle the arc surface butt, thereby prevent helical spring being close to.
Adopt this structure, owing to can make helical spring diameter and take between the aperture roughly the samely, so reception hole 15 becomes guide when helical spring stretches, play the effect that prevents to tilt.
In addition, as the example of this example in the seat surface of helical spring 18 occasion with the arc surface butt of axle 17, in order to prevent the distortion of seat surface portion, two circle or three circles of reeling of helical spring seat surface portion can being reeled.
