Abstract
The utility model belongs to automobile transmissions, and in particular relates to a novel automobile synchronizer. The novel automobile synchronizer comprises a high-speed gear joint tooth, a low-speed gear joint tooth, a single-cone synchronization ring, a tooth seat, a spring, a pushing block, a positioning block, a tooth sleeve, a double-cone intermediate ring and a double-cone inner ring. The novel automobile synchronizer is characterized in that a singe cone is adopted on a high-speed gear side; double cones are adopted on a low-speed gear side; the single-cone synchronization ring is a double-cone outer ring; and the double-cone inner ring is clamped with the tooth seat. According to the novel automobile synchronizer, the double-cone outer ring completely adopts the single-cone synchronization ring, the intermediate ring is connected with a gear cone through a bump, and the double-cone inner ring is connected with the tooth seat through the bump, so that inner and outer rings of the synchronizer and the tooth seat keep rotating synchronously, the double-cone intermediate ring and a gear rotate synchronously, the inner and outer rings and the intermediate ring relatively rotate during synchronization, two friction moments are produced, and the synchronization can be accomplished. The development difficulty and the management cost of the synchronizer are reduced. The synchronizer is high in part generality and convenient in gear-shifting.
Description
Technical field
The utility model belongs to the automotive transmission class, specifically a kind of new automobile synchronizer.
Background technique
Synchronizer is one of key components and parts in automotive transmission, and the synchronizer performance is directly determining the driving comfortability of shift of transmission performance and automobile.To improving constantly that the car steering travelling comfort requires, part automobile factory requires to adopt double-cone synchronizer on speed changer low speed gear along with the user.
Most of double-cone synchronizer is fully different from single cone synchronizer structure pattern in the market, and mould and the processing of single cone synchronizing ring and dual-cone synchronous ring can not be general.And the Capacity design such as the general employing of double-cone synchronizer, namely top gear is identical with bottom gear conical surface working diameter, but because the required synchronizer time of speed changer extension top gear is shorter, causes the relative bottom gear of related components operating life of high gear side to want high.Guaranteeing under the prerequisite in bottom gear synchronizer life-span, the top gear synchronizer life-span had relatively rich more than, caused the waste of speed changer cost.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, designing a kind of top gear side adopts single cone, bottom gear side to adopt bipyramid, and single cone synchronizing ring is the new automobile synchronizer of bipyramid outer shroud, makes it take into account Economy when improving the shift of transmission travelling comfort.
The utility model is achieved through the following technical solutions:
The utility model is a kind of new automobile synchronizer, comprise ring in top gear soldered tooth, bottom gear soldered tooth, single cone synchronizing ring, toothholder, spring, pushing block, positioning block, tooth cover, bipyramid central ring, bipyramid, it is characterized in that: adopt single cone, bottom gear side to adopt bipyramid in the top gear side, and single cone synchronizing ring is the bipyramid outer shroud.
Ring and toothholder clamping in the utility model bipyramid.
The utility model bipyramid outer shroud is used single cone synchronizing ring fully, central ring is connected with the gear cone with projection, in bipyramid, ring is connected with toothholder by projection, guarantee that the synchronizer inside and outside ring keeps synchronizeing rotation with toothholder, and bipyramid central ring and gear synchronous rotate, when synchronous, synchronous inner and outer rings and central ring relatively rotate, and produce two friction torque, guarantee synchronous completing.The utility model is due to the development difficulty that has reduced synchronizer and administration cost, and part universality is good, the gearshift is light.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is made specific descriptions;
As shown in Figure 1, the utility model by encircle 9 in top gear soldered tooth 1, single cone synchronizing ring 2, toothholder 3, spring 4, pushing block 5, positioning block 6, tooth cover 7, bipyramid central ring 8, bipyramid, bottom gear soldered tooth 10 forms, adopt single cone in the top gear side, the bottom gear side adopts bipyramid, single cone synchronizing ring 2 is the double-cone synchronizer outer shroud, clamping between ring 9 and toothholder 3 in bipyramid, its snap fit is on the end face of ring 9 in bipyramid, projection to be set, on synchronizer gear seat 3 end faces respective protrusions be provided with can with the nested groove that coordinates of projection, its protrusions and groove are generally three pairs.
working procedure of the present utility model is as follows: during down shifting, tooth cover 7 moves right under the drive of shift fork, under the effect of spring 4 and positioning block 6, pushing block 5 moves with tooth cover 7, the end contact bipyramid outer shroud of pushing block 5 (i.e. single cone synchronizing ring 2 in figure), bipyramid outer shroud rotation 1/4th circular pitches, end relief locking face on tooth cover 7 contacts with bipyramid outer shroud locking face and enters lockup state, at this moment, toothholder 3 drives the rotation of bipyramid outer shroud, the bipyramid outer shroud is identical with toothholder 3 rotating speeds, toothholder 3 drives ring 9 rotations in bipyramid simultaneously by snap fit, in bipyramid, ring 9 is also identical with the rotating speed of toothholder 3, and bipyramid central ring 8 and bottom gear soldered tooth 10 and the gear rotational speed that is connected thereof are identical, bipyramid central ring 8 is synchronising torque with bipyramid outer shroud and the interior ring 9 of bipyramid owing to existing speed discrepancy to produce friction torque, final speed discrepancy disappears, tooth cover 7 cross the double-cone synchronizer outer shroud and with 10 combinations of bottom gear soldered tooth, the end of putting into gear.
when hanging top gear, tooth cover 7 is moved to the left under the drive of shift fork, under the effect of spring 4 and positioning block 6, pushing block 5 moves with tooth cover 7, the end contact list cone synchronizing ring 2 of pushing block 5, single cone synchronizing ring 2 rotation 1/4th circular pitches, end relief locking face on tooth cover 7 contacts with single cone synchronizing ring 2 locking faces and enters lockup state, at this moment, toothholder 3 drives single cone synchronizing ring 2 rotations, single cone synchronizing ring 2 is identical with toothholder 3 rotating speeds, and the coupled gear rotational speed of top gear soldered tooth 1 is identical, single cone synchronizing ring 2 and top gear soldered tooth 1 are synchronising torque owing to existing speed discrepancy to produce friction torque, final speed discrepancy disappears, tooth cover 7 cross single cone synchronizing ring 2 and with 1 combination of top gear soldered tooth, the end of putting into gear.
