Since the sliding gear sleeve is provided with a plurality of grooves which are in bilateral symmetry, the utility model ensures the impact from the gear shifting of the cushion cylinder when the synchronizer shifts from one gear to other gear, and also ensures the accurate position of the synchronizer in neutral gear, so the gear box can realize power-taking-off when the vehicle stops; the two ends of the groove are provided with slopes, so the locking-ring on the other side of the synchronizer can enter locking state in advance while plucking the gear; and the sliding gear sleeve is also designed with a coupling gear for preventing offside, thus being capable of ensuring the gear shifting stroke.
Description
Technical field
The utility model belongs to automobile making class field, is specifically related to a kind of lock ring type odd-side synchronizer in the gearbox.
Background technique
Most of in the market odd-sides all are to adopt asymmetric structure with the sliding gear collar of lock ring type synchronizer, this asymmetric structure has caused very big difficulty to assembling, has increased working strength of workers, has reduced efficiency of assembling, simultaneously, cause loading error easily.And this synchronizer does not have neutral when switching to another gear by a gear, can not make speed changer realize the parking power taking.
Summary of the invention
The purpose of this utility model is to solve the deficiency described in the background technique, a kind of more reasonable structure is provided, uses more reliable lock ring type odd-side synchronizer.
Technical solution of the present utility model is: the utility model is a kind of lock ring type odd-side synchronizer, comprise the tooth hub, be arranged on a plurality of pins in the tooth hub and be set in the sliding gear collar of tooth hub end, its special way is: be provided with a plurality of grooves corresponding to pin on the internal ring wall of described sliding gear collar.
Also be provided with slide block between above-mentioned tooth hub and the sliding gear collar, this slide block and sliding gear collar are all about axially symmetry, the center line of pin and the coincidence of slide block center of tooth hub medial axis.
Above-mentioned synchronizer also includes low gear side outer conical ring of friction and the interior conical ring of low gear side friction that is arranged on tooth hub one side, and conical ring all embeds the tooth hub in low gear side outer conical ring of friction and the friction of low gear side.
The two ends of above-mentioned groove respectively are provided with a slope, and extend outside the top of groove is oblique on this slope.
The internal ring wall of above-mentioned sliding gear collar is provided with anti-offside connection tooth.
Because the utility model is by being provided with a plurality of grooves to sliding gear collar, and bilateral symmetry, thereby guarantee that synchronizer is when switching to another gear by a gear, the impact that brings during the bounce cylinder gearshift, guarantee the accurate location of synchronizer when neutral simultaneously, make speed changer can realize the power taking of stopping.Two ends at groove are provided with the slope, guarantee that synchronizer when plucking retaining, makes the lock ring of synchronizer opposite side enter lockup state in advance; Also designing on the sliding gear collar has anti-offside connection tooth, can guarantee the stroke of shifting gears accurately.Conical ring all embeds the tooth hub in low gear side outer conical ring of friction simultaneously of the present utility model and the friction of low gear side, directly drive conical ring rotation in low gear side outer conical ring of friction and the friction of low gear side by the tooth hub, changed traditional indirect drive mode, further guaranteed the synchronism of lock ring type odd-side synchronizer by conical ring in the moving low gear side friction of low gear side friction outer cone endless belt.

Embodiment
Shown in Fig. 1,2, lock ring type odd-side synchronizer provided by the utility model, comprise that conical ring 3, low gear rub conical ring 10, high gear in conjunction with gear ring 11 in conjunction with gear ring 4, sliding gear collar 5, tooth hub 6, slide block 7, pin 8, spring 9, high gear side in the outer conical ring 1 of low gear side friction, low gear side friction central ring 2, the friction of low gear side, wherein, the high gear side adopts single cone structure, high gear side friction conical ring 10 links to each other with transmission output shaft 15 by tooth hub 6, and the high gear side links to each other with high gear side gear 12 in conjunction with gear ring 11; The low gear side adopts biconical surface structure, outer conical ring 1 of low gear side friction and low gear side friction central ring 2, low gear side friction central ring 2 and the interior conical ring 3 of low gear side friction, form two pairs of friction pairs respectively, the outer conical ring 1 of low gear side friction all is connected with synchromesh gear hub 6 with the interior conical ring 3 of low gear side friction, and be connected with transmission output shaft 15 by tooth hub 6, low gear side friction central ring 2 is connected in conjunction with gear ring 4 with low gear, and is connected with low gear gear 13 in conjunction with gear ring 4 by low gear.
Design has a plurality of grooves 16 on the sliding gear collar 5, and bilateral symmetry, and simultaneously, a slope 17,18 has been designed on the both sides of groove 16 respectively, can guarantee synchronizer when plucking retaining, makes the lock ring of synchronizer opposite side enter lockup state in advance.Many group spring 9, pin 8 and slide blocks 7 are housed in the tooth hub 6, corresponding with the groove 16 on the sliding gear collar 5 respectively, thereby guarantee that synchronizer is when switching to another gear by a gear, the impact that brings during the bounce cylinder gearshift, guarantee the accurate location of synchronizer when neutral simultaneously, make speed changer can realize the power taking of stopping.In addition, also designing on sliding gear collar 5 internal ring walls has anti-offside connection tooth 19, can guarantee the stroke of shifting gears accurately.
Referring to Fig. 3,4,5, when high gear switches to low gear, sliding gear collar 5 moves right, combining gear ring 11 disengagements with high gear and arriving neutral gear position on the sliding gear collar 5 in conjunction with tooth, in this process, the inclined-plane 18 on sliding gear collar 5 right sides can promote pin 8 and slide block 7 moves right, slide block 7 can promote the outer conical ring 1 of low gear sides friction with friction pair (outer conical ring 1 of low gear side friction and low gear side friction central ring 2 at this moment, low gear side friction central ring 2 and the interior conical ring 3 of low gear side friction, the friction pair of Zu Chenging respectively) compresses, because the existence of speed discrepancy between friction pair, make the outer conical ring 1 of low gear side friction rotate an angle, because the conical surface compresses, so produce friction, the beginning synchronizing process, speed discrepancy until 15 of low gear gear 13 and transmission output shafts is zero, and synchronizing process finishes, and sliding gear collar 5 continues to move right until combining gear ring 4 with low gear in conjunction with hanging up low gear.
It is identical with above-mentioned principle to switch to high gear by low gear.
