Please refer to shown in Fig. 1, Fig. 2, the utility model embodiment one provides a kind of synchronizer, comprising:
Tooth hub 3, has along the circumferential outer edge 30 of tooth hub 3 successively spaced a plurality of annular groove 31, a plurality of slide block slot 32 and a plurality of bracket groove 35;
Tooth coaxial and that be slidably mounted on tooth hub 3 overlaps 4, and the circumferential inner surface of tooth cover 4 is provided with spline 40;
Be arranged on correspondingly a plurality of slide blocks 2 in a plurality of slide block slots 32 of tooth hub 3;
Synchronizing ring 1 in the coaxial a plurality of annular grooves 31 that are arranged on tooth hub 3, synchronizing ring 1 has the multipair projection 11 protruding towards tooth hub 3;
Be arranged on correspondingly a plurality of supports 5 in a plurality of bracket grooves 35 of tooth hub 3, support 5 comprises pedestal 50 and protrudes from pedestal 50 boss 52 extending, pedestal 50 protrudes pedestal 50 surfaces with boss 52 connecting parts and is provided with the raised line 51 compressing mutually with bracket groove 35, pedestal 50 two ends form the leg 53 with arc outer rim, the multipair projection 11 of synchronizing ring 1 is inserted into respectively in a plurality of bracket grooves 35 in couples one by one, and a pair of projection 11 being inserted in same bracket groove 35 forms Spielpassung with two legs 53 that are arranged on a support 5 in corresponding bracket groove 35 respectively, radially convex platform 52 at synchronizer connects with spline 40.
Particularly, support 5 is roughly convex shape, and raised line 51 compresses mutually with bracket groove 35, plays the effect of the lever strong point, and for example, when boss 52 is subject to the power consistent with raised line 51 protrusion directions, support 5 can rotate around raised line 51.Raised line 51 is along the length direction setting of pedestal 50, and the cross section of raised line 51 is any in arch, rectangular, square, trapezoidal and polygonal.The both ends of the surface of raised line 51 are arc shaped surface.In the footpath of synchronizer, convex 51 is greater than the distance of raised line 51 and two legs 53 with the distance of boss 52, has like this effect of boosting lever when shifting gears.Boss 52 has circular arc seamed edge 520.
Please refer to again shown in Fig. 3, the bracket groove 35 of tooth hub 3 forms opening in the circumferential outer edge 30 of tooth hub 3, when support 5 is installed to bracket groove 35 correspondingly, boss 52 is contained in this opening, between two leg 53 ends of each support 5 and the two ends cell wall of place bracket groove 35, forms respectively accommodation section 351.Synchronizing ring 1 is during with 3 assembling of tooth hub, and a pair of projection 11 is housed in respectively in two accommodation sections 351 of corresponding bracket groove 35 interior formation, and is arranged between two legs 53 of a support 5 in same bracket groove 35 and has respectively certain interval, forms Spielpassung.Figure 3 shows that example, when synchronizing ring 1 rotates counterclockwise, the projection 11 that is positioned at support 5 right sides compresses the leg 53 on support 5 right sides, because leg 53 has arc outer rim, thereby stressed being lifted, being equivalent to the leg 53 of support 5 around left side and rotating, the right side of boss 52 will raise diametrically.
Shown in Fig. 1 and Fig. 4, tooth cover 4 assembles by spline with tooth hub 3, and tooth hub 3 slides relatively, and wherein tooth hub 3 circumferential outer surfaces are provided with external splines, and tooth overlaps 4 circumferential inner surfaces and is provided with internal spline.Tooth hub 3 completes after assembling with tooth cover 4, is arranged on slide block 2 on tooth hub 3 and support 5 and all overlaps 4 circumferential inner surfaces with tooth and join.
The improvement of the present embodiment synchronizer is, in existing synchronizer structure, increase a plurality of support 5(and be preferably 3, bracket groove 35 is also 3,3 supports one by one correspondence are arranged in 3 bracket grooves 35 and spaced set), realization is when extension reverses gear, the axle at reverse gear place is carried out to reduction of speed braking, and the extension of being convenient to reverse gear, and does not affect again the use of synchronizer while hanging top gear simultaneously.Working principle below in conjunction with the synchronizer of Fig. 5-8 pair the present embodiment describes.
Please refer to shown in Fig. 5, while hanging top gear (five gears), tooth cover 4 slides to the right, promoting slide block 2 also slides to the right, slide block 2 promotes synchronizing ring 1 again and completes after presynchronization, and tooth cover 4 is hung into top gear, now, the spline 40 of the tooth cover 4 of support 5 correspondences is inoperative, and the synchronizer of the present embodiment is equivalent to a traditional inertial lock ring type synchronizer.
Simultaneously with reference to shown in Fig. 6, Fig. 7, hang while reversing gear, tooth cover 4 slides left again, and the boss 52 on the spline 40 promotion supports 5 relative with support 5 is to left movement, and the arc seamed edge 520 that boss 52 has is convenient to boss 52 and is slided on the inclined-plane 41 of spline 40.Because the raised line 51 on support 5 is pressed on tooth hub 3, boss 52 to left movement, two legs 53 of support 5 are overturn to the right, promote synchronizing ring 1 and move right with the cone of friction (not shown) of reverse gear and contact.Because the existence of speed difference produces friction torque, synchronizing ring 1 is rotated, the projection 11 of synchronizing ring 1 carrys out one of them leg 53 jack-up of support 5, makes the boss 52 of support 5 and spline 40 lockings of tooth cover 4, and tooth cover 4 can not continue toward the direction motion of reversing gear.Particularly, the inclined-plane 41 of spline 40 is pressed on boss 52 between inclined-plane 41 and the bracket groove 35 of tooth hub 3, and when extension is reversed gear, synchronizing ring 1 and cone of friction speed difference disappearance front boss 52 are locked between inclined-plane 41 and the bracket groove 35 of tooth hub 3.Until after synchronizing ring 1 and the disappearance of cone of friction speed difference, tooth cover 4 is just crossed boss 52, continuation is by the extension direction motion (as shown in Figure 8) of reversing gear, and now the reverse gear rotating speed on the same axis has dropped to easy extension into the rotating speed reversing gear (0 or extremely slow rotating speed) with cone of friction.
As from the foregoing, the present embodiment is increasing on the basis of installing space hardly, through the improvement design to existing synchronizer, increase support is set, make it have the function of conventional synchronizer and lever synchronizer, when hanging top gear, realize the function of conventional synchronizer, when extension reverses gear, realize the function of lever synchronizer, while having avoided reversing gear without synchronizer, put into gear and beat tooth problem and lever synchronizer excessive problem of gear shifting force when hanging top gear.
Synchronizer corresponding to the utility model embodiment one, the utility model embodiment two provides a kind of automobile, have the synchronizer described in the utility model embodiment one, the structure of this synchronizer and working principle refer to the utility model embodiment one explanation, also repeat no more herein.
Above disclosed is only the utility model preferred embodiment, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
