Abstract
The invention relates to a gear engaging limiting structure for a synchronizer. Combining teeth, an inner ring, a middle ring, an outer ring, a toothholder and a toothed sleeve are sequentially arrayed on one axis of the synchronizer. A sliding block groove and a limiting groove are formed in a spline part of the toothed sleeve, a sliding block is embedded in a groove of the toothholder, and a limiting block is arranged in the groove of the toothholder; an internal spline is arranged on the toothed sleeve, an external spline is arranged on the toothholder, the toothed sleeve is arranged on the toothholder in a sleeving mode through the splines, and a spring butts the sliding block in a sliding cover groove in the inner wall of the toothed sleeve; the limiting block has the limiting effect on gear engaging of the synchronizer, the distance between the sliding cover groove and the limiting groove is equal to the gear engaging stroke, and in the gear engaging process, the combining teeth are engaged to the limiting block to stop gear engaging. The gear engaging limiting structure has the advantages that multiple product requirements can be met through one cutter, and time and money are saved. Different from the limiting mode of previous products, the manufactured cutters of the previous products are diverse, and the management cost and cutter cost are huge. According to the limiting mode, multiple products can be machined through the cutter, the design is optimized, and resources are used reasonably.
Description
Technical field
The present invention relates to automobile manufacturing field, especially relate to a kind of synchronizer and to put into gear limit structure.
Background technique
Most of automotive transmission adopts synchronizer gearshift in the market, and excessive for preventing synchronizer gear sleeve from hanging, cause synchronizer spring and synchronizer positioning block to come off, cause synchronizer to lose efficacy, synchronizer is provided with position-limit mechanism; The limit method variation of automobile synchronizer in the market, its construction cost is high, make trouble.
Summary of the invention
For overcoming the problems referred to above, the concrete scheme that the present invention adopts is as follows:
A kind of synchronizer is put into gear limit structure, an axis is arranged in sequence with synchronizer in conjunction with tooth, inner ring, central ring, outer shroud, toothholder and tooth cover, is characterized in that: the spline part of described tooth cover is arranged with slide block slot and restraining groove, slide block is embedded in the groove of toothholder, and limiting stopper device is at the groove of toothholder.
Described tooth has put internal spline, and toothholder has external splines, and tooth cover is by spline housing on toothholder, and slide block withstands in the slip lid groove of tooth cover inwall by spring.
Described limiting stopper have been put into gear position-limiting action to synchronizer, and this is enough convenient and swift, and not only its manufacture cost, technological advantage are given prominence to, in addition its engage a gear rapidly, level and smooth.
The distance of described slip lid groove and restraining groove equals stroke of putting into gear.
When putting into gear, in conjunction with tooth put into gear limiting stopper part stop.
Advantage of the present invention is: one cutter can be met multiple product demand, has saved the waste of time with money.Product limit method is in the past different, and its cutter manufactured is also diversified, and administration expenses, cutter expense is extremely huge.Our this limit method one multiple for cutter Product processing, both can optimize design, reasonably make use of resource again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the schematic diagram of limit structure of the present invention.
Embodiment
As shown in Figure 1, 2, a kind of synchronizer is put into gear limit structure, an axis is arranged in sequence with synchronizer in conjunction with tooth 1, inner ring 2, central ring 3, outer shroud 4, toothholder 5 and tooth cover 6, the spline part of tooth cover 6 is arranged with slide block slot and restraining groove, and slide block 7 is embedded in the groove of toothholder 5, and limiting stopper 8 device is at the groove of toothholder 5.
Described tooth cover 6 has internal spline, toothholder 5 has external splines, tooth cover 6 is by spline housing on toothholder 5, and slide block 7 is withstood on tooth and overlaps in the slip lid groove of 6 inwalls by spring.
Described limiting stopper 8 pairs of synchronizers have been put into gear position-limiting action.
The distance of described slip lid groove and restraining groove equals stroke of putting into gear.
When putting into gear, in conjunction with tooth 1 put into gear limiting stopper 8 part stop.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any those of ordinary skill in the art are in the technical scope disclosed by the present invention; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
