Abstract
The utility model discloses an improved anti-abrasion synchronizer. The improved anti-abrasion synchronizer comprises a shell. The shell comprises a middle support. The two ends of the middle support are provided with a first connecting ring and a second connecting ring respectively, the first connecting ring and the second connecting ring are connected with the middle support in a sliding mode, a conical cavity is formed in the inner portion of the shell, an inner sleeve and an outer sleeve are arranged inside the conical cavity, and the conical cavity, the outer sleeve and the inner sleeve are connected in sequence in a sleeved mode. The performance of the synchronizer is superior to that of a common synchronizer, the cost is low, the structure is reasonable and the synchronizer is economical and practical. The connecting rings are prevented from deflecting, therefore, generation of the noise is prevented and the stability of running of the connecting rings is improved.
Description
Technical field
The utility model relates to a kind of improved wear-resisting synchronizer, belongs to the automobile part field.
Background technique
At present, synchronizer has been widely used in the gear-driven automotive transmission of mechanical type, due to its use, make the performance of mechanical type manual speed-changer greatly improve, not only make gear shift light, avoid impacting, make simultaneously the mean lifetime of speed changer and whole power train also be improved, also be conducive to improve power character and the fuel economy of automobile.Exchange the raising of block sense requirement along with engine technology development and client, single cone synchronizer can not meet the demands gradually, so double-cone synchronizer occurs.But double-cone synchronizer is when satisfying the gearshift performance, also appeared cost high, be subjected to the deficiency such as transmission dimensions restriction.
The model utility content
For the deficiency that prior art exists, technical problem to be solved in the utility model is, a kind of improved wear-resisting synchronizer is provided, and avoided connecting ring generation beat, and then avoided the generation of noise, improved the stability of connecting ring running.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of improved wear-resisting synchronizer, comprise shell, its shell comprises an intermediate support, the two ends of intermediate support are respectively arranged with the first connecting ring and the second connecting ring, and the first connecting ring and the second connecting ring and intermediate support are slidably connected; Described enclosure is provided with a conical cavity, is provided with inner sleeve and outer sleeve in conical cavity, and conical cavity, outer sleeve and inner sleeve are socketed successively.
Optimize, above-mentioned improved wear-resisting synchronizer, the front end of its inner sleeve is a step surface, the rear end of step surface is provided with fluted disc.
Optimize, above-mentioned improved wear-resisting synchronizer, its outer sleeve inside is provided with the stepped slot that coordinates with step surface, and the front end of outer sleeve is provided with outer tooth disk, and the rear portion of outer tooth disk is provided with pitch face.
Optimize, above-mentioned improved wear-resisting synchronizer, the internal surface of its conical cavity is provided with the groove that coordinates with pitch face.
Optimize, above-mentioned improved wear-resisting synchronizer is provided with spring groove between its first connecting ring and the second connecting ring and intermediate support, is provided with spring in spring groove, and the two ends of spring contact with the second connecting ring with the first connecting ring.
The performance of the utility model synchronizer is better than common synchronizer, and is with low cost, rational in infrastructure, economical and practical; Avoid connecting ring generation beat, and then avoided the generation of noise, improved the stability of connecting ring running.
