The lock unit of speed changer shown in Figure 1, described lock unit has the sync-body 10 be coupled with the driving axis that can rotate around transmission axis A, and described sync-body is provided with outer toothed portion.But gearshift clutch collar 12 torsionally can axially movably be positioned in sync-body 10.Gearshift clutch collar 12 can be contrary vertically direction move, to be pulled in clutch teeth portion 14 or clutch teeth portion 16.
Clutch teeth portion 14 and forward gear, the unshowned gear of especially the highest forward gear is associated, and clutch teeth portion 16 is associated with the gear of reverse gear shift.In order to distinguish relatively easily, also apply term " forward gears " and " forward gears clutch teeth portion " and " reverse gear shift gear " and " reverse gear shift engagement sleeve teeth portion " below.
Clutch teeth portion 14,16 can torsionally be coupled with the gear be associated in a different manner.Clutch teeth portion such as can be formed on corresponding gear.In addition, they can be formed in separately, be connected on gear parts to be fixed on.At this, a possibility is, uses so-called clutch body 18, described clutch body is fixed on gear (shape engage ground, power ordinatedly and/or material engage ground), and also still there is cone of friction 20.3rd possibility is, uses the clutch disk 22 without cone of friction.Clutch teeth portion 16 is arranged on clutch disk 22.
Friction ring 24 is placed on cone of friction 20, and described friction ring has inner conical surface, and described inner conical surface to be preferably equivalent to cone of friction 20 in its gradient.The projection 26 of multiple finger-shaped is axially given prominence to from friction ring 24.
The feature of lock unit shown here is, there is friction ring 24 only in sync-body 10 in the axial side of the clutch body 18 be connected with forward gears, on the contrary, there is not friction ring on the opposite sides.
In sync-body 10, be provided with multiple recess 25 for locating inertia-type Synchronization Component 28, described inertia-type Synchronization Component is arranged in the recess 30 of the window shape in sync-body 10.
Each inertia-type Synchronization Component 28 comprises supporting member 32, and described supporting member is preferably configured to pin and extends radially outwardly.
Supporting member 32 is pre-tensioner by spring element 34 radially outward be close in inner side thereon.
The retainer 36 separated with supporting member coordinates with supporting member 32, and described retainer is preferably close on supporting member 32, and surrounds supporting member at least partly.
The groove 38 extended by the longitudinal axis here perpendicular to supporting member 32 that is coupled of supporting member 32 and retainer 36 is realized, and described groove is radially outwardly through inclined-plane 40 gauge.
On this inclined-plane and the inclined-plane 42 (see accompanying drawing 2 and 3) extended in groove 38 of being close to of this inclined-plane 40 and retainer 36 coordinates.
Retainer 36 is radially observed, and have the radial top side of the U-shaped with two axially extended supporting legs (see Fig. 1, being positioned at retainer 36 below), inclined-plane 42 (see Fig. 2) is between described two supporting legs, but this is optional.
The radial bottom side of retainer 36 is provided with radially-inwardly outstanding projection 44, and described projection is especially arranged on (see Fig. 1) on the free end of supporting leg.Each projection 44 has the stop surface 46 (see Fig. 4) of inclination, and wherein stop surface 46 is observed in the axial direction, mutually extends obliquely.
In the region charging between stop surface 46 of projection 26 part of friction ring 24 (see Fig. 4), described projection has stop opposing side 48 at its free end, and described stop opposing side preferably tilts corresponding to stop surface 46.
Shown in figure 2 on position, gearshift clutch collar 12 is positioned at neutral position or neutral position.Supporting member 32 has band and is bevelledly preferably spherical end, described end is positioned to may be locked in the recess 49 on the inner side of gearshift clutch collar 12, inertia-type Synchronization Component 28 is remained on neutral neutral position together with gearshift clutch collar 12, described neutral position occurs drag torque hardly.Recess 49 is also provided with inclined-plane.
When the direction of clutch collar 12 towards forward gears of shifting gears moves axially, due to the gradient on the end of supporting member 32 and the corresponding relative steepness in the recess 49 of gearshift clutch collar 12, supporting member 32 produces power, and described force is asked and supporting member 32 is inwardly moved.By inclined-plane 40,42, supporting member 36 moves axially (arrow see in Fig. 3) towards the direction of friction ring 24.
Due to the minimum drag torque occurred, friction ring 24 rotates according to sense of rotation to the left or to the right relative to the desirable neutral position according to Fig. 4, on the stop opposing side 48 stop surface 46 being close to be associated.
Therefore, when retainer 36 moves axially (arrow see in Fig. 4), retainer 36 is in axial direction pressed against on friction ring 24, makes fixing being pressed on cone of friction 20 of the inner conical surface of this retainer, and with this cone of friction rubbing contact.
Stop surface 46 and its stop opposing side 48 form angle, make to be applied on clutch collar 12 and the displacement force passing to face 46,48 makes friction ring 24 till reaching synchronization, can not forward neutral position to convolution.
It is synchronous that rotating speed by gear reaches with the rotating speed of sync-body 12, and the torque between friction ring 24 and retainer 36 declines suddenly, makes the gear shifting force of the axis by clutch collar 12, friction ring 24 can be extruded towards the direction in neutral position according to Fig. 4.Therefore, allow stop-motion body 36 to continue to move towards the direction of friction ring 24, projection 26 can be moved to deeper and formed in gap by stop surface 46.
Based on the offset movement (arrow see the level in Fig. 3) of retainer 36, supporting member 28 radially more upcountry can be extruded from recess 49, so that final release is for the path of clutch collar 12 of shifting gears.Gearshift clutch collar 12 the most at last clutch teeth portion 14 is coupled with the outer toothed portion in sync-body 10.
If as just mentioned, friction ring 24 slightly towards back rotation and retainer 36 move, so reach release position.
Stop position is as upper/lower positions, and in described position, stopped radially-inwardly directed being synchronized with the movement of supporting member 32 by retainer 36, stop-motion body 36 stops gearshift clutch collar 12 to continue to move axially towards the direction of gear.
If gearshift clutch collar 12 is taken to neutral position or neutral position again, so supporting member 32 is locked in corresponding recess 49 again based on spring element 34, and friction ring 24 and cone of friction 20 separate and carry retainer 36.
If should reverse gear shift be inserted, so vehicle stationary, make clutch body 18 be connected with the output shaft of transmission device and the gear be therefore also connected with car-wheel is also static.The sync-body 10 of still rotating due to moment of inertia must be braked, to be connected with torque mode with the static gear for reverse gear shift.
Friction ring 24 is same is the synchronizing process of zero for this to rotating speed.This can carry out as follows, namely steering equipment is configured to by retainer 36, supporting member 40 and gearshift clutch collar 12 and projection 26, the motion in the direction towards reverse gear shift gear of gearshift clutch collar 12 to be converted to the motion be pressed onto by friction ring 24 on cone of friction 20.
This steering equipment realizes as follows, and namely by also when by recess 49 and the inclined-plane on the free end of supporting member 32, (see Fig. 3's clutch collar 12 of shifting gears) moves to the right, supporting member 32 radially-inwardly extrudes again, to make retainer 36 move axially.
Also in this process, first between cone of friction 20 and sync-body 10, there is speed discrepancy, friction ring 24 is along the circumferential direction rotated slightly relative to position in the diagram.Then, one in stop surface 46 is close on its stop opposing side 48 be associated (stop position), make to hinder supporting member 32 radially-inwardly to continue motion, and therefore supporting member is arranged in the recess of gearshift clutch collar 12 and stops the motion of gearshift clutch collar.
After sync-body 10 is braked completely, just reach release position, on described release position, gearshift clutch collar 12 finally can be pulled in clutch teeth portion 16.
Be supporting member 32 in form of implementation shown in Fig. 1 to 4, described supporting member is directly close to the clutch collar motion and obstruction is shifted gears on gearshift clutch collar 12, because prevented the motion of supporting member 32 itself by retainer 36.
In the form of implementation of such as Fig. 5 to 8, the parts that function is identical are provided with the identical reference character adopted, and make it possible to omit elaborating of they, and just discuss difference.
In this embodiment, inertia-type Synchronization Component 28 improves relative to aforementioned inertia-type Synchronization Component 28.Also be provided with pin-shaped supporting member 32 here, described supporting member is contained in the hole 25 in sync-body 10.Here, supporting member 32 also has the bevelled spherical free end of band, when clutch collar 12 of shifting gears be positioned at according on the neutral position of Fig. 6 and 7 or neutral position time, described free end is positioned in the recess 49 on the inner side of gearshift clutch collar 12.
On supporting member 32 or around supporting member 32, be provided with retainer 36, the medial axis X of the imagination that described retainer can extend around the radial direction of supporting member 32 rotates.
Supporting member 32 radially-inwardly deflects, and wherein in order to realize relative movement, also can there is bearer ring 60 (see Fig. 7), and described bearer ring can be the sliding bearing for the radial motion of supporting member 32 and the rotary motion for retainer 36.
Also can imagine, supporting member 32 and retainer 36 are directly mutually coupled or are mutually integrally formed, and make it possible to realize the rotary motion in access aperture 25.
Retainer 36 has multiple finger shape plate 50 radially with respect to medial axis X projection, described finger shape plate is formed cross-shaped generally in shown form of implementation, wherein in two axial side, forms recess 52 between two finger shape plate 50.This recess 52 forms forked, and by finger shape plate 50 towards stop surface 46 gauge that medial axis X extends mutually.
Friction ring 24 is provided with radial outstanding projection 26 (see Fig. 5).Projection 26 is charged in the recess 52 between finger shape plate 50 (see Fig. 8).This projection 26 is configured to tapered gradually in a radial view, and has stop opposing side 48 directed on the contrary in a circumferential direction, and described stop opposing side is positioned at the opposite of the stop surface 46 in finger shape plate 50.
Gearshift clutch collar 12 has radially-inwardly directed extension part 56 on its radially inner side, and described extension part is charged in the gap between the axial finger shape plate 50 relatively extended (see Fig. 8).
Extension part 56 distance in a circumferential direction slightly larger than retainer 36 its accurately axial orientation time width, be namely positioned at the width (see Fig. 8) of release position.
When moving forward, being obtained by little drag torque and friction torque and acting on torque on friction ring 24, this friction ring being rotated slightly, and equally slightly rotates (dotted line see in fig. 8) according to the retainer 36 of Fig. 8 at this.The inclined-plane 40 of finger shape plate 50 is pressed against the inclined-plane 42 be associated on extension part 56.Inclined-plane 40,42 is preferably close to mutually completely.
If gearshift clutch collar 12 extrudes (see Fig. 8) left by its extension part 56, so therefore cause, retainer 36 is in reverse to the direction of arrow to back rotation.The inclined-plane of all mutual inclinations, namely inclined-plane 40,42, harmonious, makes until reach forward gears and sync-body 10 synchronization, on the release position shown in retainer 36 all can not forward in fig. 8 to convolution.
If then reach this synchronization, so retainer 36 can turn to convolution, and release is for the path in axial direction of clutch collar 12 of shifting gears.So, determine that the supporting member 32 in the neutral position of gearshift clutch collar 12 radially-inwardly offsets.In this form of implementation, be only the retainer 36 directly stopped for the path of clutch collar 12 of shifting gears.
If insertion reverse gear shift, due to the speed discrepancy of forward gears and sync-body 10, retainer 36 rotates equally.So stop the path for clutch collar 12 of shifting gears at be arranged in right side with reference to figure 8 one of two finger shape plate 50, because corresponding projection is close to by its inclined-plane 42 on the inclined-plane 40 that is associated equally.
Here, also due to the axial motion to the right by steering equipment and inclined-plane 40,42 and stop surface 46 and stop opposing side 48 and the axial force of gearshift clutch collar 46, the axial motion in the direction towards cone of friction 20 of friction ring 24 is realized.In addition, realize being used for the synchronous of reverse gear shift by the friction ring 24 on the side of forward gears.
When sync-body 10 is no longer rotated, friction ring 26 can move to release position according to Fig. 8, to discharge the path towards clutch teeth portion 16 for clutch collar 12 of shifting gears from stop position.
