Description
Technical field
The utility model relates to a kind of manual gear of vehicle, is meant a kind of three conical-surface-type synchronizer of Automotive manual transmission especially.
Background technique
At present, adopt single conical surface type synchronizer at home and abroad in the manual gear of vehicle mostly, include shifting gear, synchro converter ring, tooth cover and tooth hub assembly, shifting gear is provided with gear combining tooth, and synchro converter ring cooperates with gear combining tooth, and the two forms synchronously and rotates, in rotating synchronously, synchro converter ring and gear combining tooth are in relative position, make synchronizer gear sleeve can enter the gear combining tooth transferring power smoothly, finish the gear shift action.The speed changer that this transmission power is bigger is more painstaking when gear shift, and the phenomenon of bad engage a gear is especially obvious, and it is bigger that the driver operates strength ratio.Single conical surface type speed changer is owing to be subjected to the restriction of structure space simultaneously, and it is little to make axial dimension adjust the space, especially when low speed one, second gear, moment of torsion rotates bigger, the two occurs and synchronously badly cause greater impact to produce noise, and the tooth cover easily impacts with gear combining tooth, working life is short.
For this reason, application number is: 01280043.0, notice of authorization number is: CN 2513822Y, patent name improves speed changer list conical surface type synchronizer for the utility model patent of " twin cone lock ring synchronizer ", adopts and forms two secondary participation runnings of synchronous cone of friction between external cone, internal cones and synchronizing cone three.Though this model utility is improved original technology, effect is not very desirable, and gear shift still has retardance, and the gear shift dynamics still needs bigger than normal.
Summary of the invention
The utility model is in order to solve the deficiency that above-mentioned prior art exists, provide a kind of rational in infrastructure, compact, operate succinct, light three conical-surface-type synchronizer of Automotive manual transmission, avoided automobile when the change into lower gear position, the phenomenon of engage a gear, engage a gear impact and noise occurs being difficult for.
For achieving the above object, the utility model adopts following scheme: a kind of three conical-surface-type synchronizer of Automotive manual transmission, include shifting gear, interior ring, conical ring, outer shroud, tooth cover and tooth hub assembly, ring in described, conical ring and outer shroud are set on the circular frustum of shifting gear from inside to outside successively, on circular frustum opening end, offer at least two above square grooves, the conical ring small end face is provided with the projection that is complementary with square groove, conical ring can be connected with shifting gear by the square groove on the circular frustum, interior ring large end face is provided with at least two above overhead kicks, and the overhead kick on the interior ring is placed in the groove that outer shroud large end face place is complementary with it.
The utility model further is set to: offer three square grooves on the described circular frustum opening end, interior ring large end face is provided with three overhead kicks, and outer shroud is provided with three grooves that are connected with overhead kick on the interior ring.
Described circular frustum, interior ring, conical ring and outer shroud have an identical tapering, and range of taper is 7 ° to 9 °.
The beneficial effects of the utility model are: the utility model is compared with original technology, adopt outer shroud and conical ring, conical ring and interior ring, three pairs of conical surface type friction pair structures that form between interior ring and shifting gear frustum, finishing the tooth cover by single conical surface type of past or two conical surface types combines tooth rotation synchronously and becomes by three conical surfaces and finish this process with shifting gear, increased the friction torque of gear synchronizing process, thereby reduced berth-changing strength and shortened the synchronous deadline, effectively improved net synchronization capability, avoided in the past automobile simultaneously when the change into lower gear position, engage a gear appears being difficult for, engage a gear impacts and the phenomenon of noise, has improved the travelling comfort of car load.
Below in conjunction with embodiment and accompanying drawing the utility model is further specified.
