Abstract
The utility model discloses a six-claw type intermediate ring used for an automobile synchronizer, which comprises a conical ring body provided with six convex claws. Sinking platforms are arranged at the bottom of both sides of each pawl. A transition arc-shaped surface is arranged between each sinking platform and the corresponding pawl. A transition inclined plane is arranged between one side of each sinking platform and the end surface of the conical ring body. The conical ring body is made of high carbon chromium bearing steel and the convex pawls are also made of high carbon chromium bearing steel. Since the conical ring body and the convex pawls both made of high carbon chromium bearing steel adopt an integrated structure, thus are high in hardness and good in wear resistance. A transition inclined plane is arranged between one side of each sinking platform and the end surface of the conical ring body, so that the effective contact area of the part of each pawl in fit with the side surface of a gear is increased and the stress applied on the root part of each sinking platform is reduced. Meanwhile, due to the adoption of the above structure, the anti-impact force of the convex pawls is increased. Therefore, the quality of the six-claw type intermediate ring used for an automobile synchronizer is increased.
Description
Technical field
The utility model relates to the assembly in a kind of synchronizer, particularly relates to a kind of six-paw type central ring that is used for automobile synchronizer.
Background technique
Current China automobile industry presents day by day significantly internationalization feature; The tariff barrier of imported auto weakens day by day; Automobile industry internationalization paces quicken; Automobile trans-corporation all gets into China's automobile industry with direct or indirect mode, and paces are accelerated because its auto parts and components of price factor are sought to domesticize, to adapt to the downward trend of car load part price.The synchronizer central ring, as the part of speed control system of car, its function is the synchronizing ring inner conical surface with after gear ring male cone (strobilus masculinus) to be joined contacts; Under the effect of friction torque, both rotate synchronously, and gear is zero with respect to the rotating speed of synchronizing ring; And further engage with the gear ring of gear to be joined; And accomplish gearshift, in the process of gear shift operation, synchronizer central ring mobile has certain impact property; Disconnected pawl takes place in actual use easily, and the wearing and tearing of conical ring body have simultaneously been pulled phenomenon and have also been compared serious.On the other hand, external central ring product adopts the steel for carburizing material mostly, in the course of working of reality, needs to have improved the price of product through technologies such as carburizing and quenchings.
Because the defective that above-mentioned existing synchronizer central ring exists, the design people actively studies innovation; In the hope of founding a kind of six-paw type central ring that is used for automobile synchronizer of new structure, adopt high-carbon-chromium bearing steel cooling impact briquetting or forge the car moulding, because the high-carbon-chromium bearing steel combination property is good; Has good machinability after the spheroidizing annealing; Quench and temper number height and even, wear-resisting property and contact fatigue strength are high, and hot-working character is good; Price is relatively cheap, has practicability.
The model utility content
The main purpose of the utility model is; Overcome the defective that existing synchronizer central ring exists; And a kind of six-paw type central ring that is used for automobile synchronizer of new structure, technical problem to be solved are provided is to make the hardness of its six-paw type central ring high, and wear-resisting property is good; Thereby be suitable for practicality more, and have the value on the industry.
The purpose of the utility model and solve its technical problem and adopt following technological scheme to realize.A kind of six-paw type central ring that is used for automobile synchronizer according to the utility model proposes comprises the conical ring body, it is characterized in that; Said conical ring body is provided with six dogs; Said dog two side bottoms are provided with heavy stand, and said heavy stand and said dog are through the arc surface transition, and a side of said heavy stand and the end face of conical ring body pass through chamfered transition; Said conical ring body is a high-carbon-chromium bearing steel conical ring body, and said dog is the high-carbon-chromium bearing steel dog.
The aforesaid six-paw type central ring that is used for automobile synchronizer, wherein, said conical ring body and said six dogs are integral structure.
The aforesaid six-paw type central ring that is used for automobile synchronizer, wherein, said six dogs are evenly distributed on the said conical ring body.
The aforesaid six-paw type central ring that is used for automobile synchronizer, wherein, the inclined-plane angle of a side of said heavy stand and said conical ring body end face is 10 °.
By technique scheme, the beneficial effect that the utility model is used for the six-paw type central ring of automobile synchronizer is:
Adopt the high-carbon-chromium bearing steel conical ring body and the dog of integral structure; Hardness is high, and wear-resisting property is good, and a side of heavy stand and conical ring body end face are through the design of chamfered transition; Increased effective area of contact of dog and gear side mating part; Reduced the stress of heavy stand root, and this structure improves the anti-impact force of dog, and then improved the quality that model utility is used for the six-paw type central ring of automobile synchronizer.
In sum, the six-paw type central ring that is used for automobile synchronizer of the utility model special construction, it has above-mentioned many advantages and use value, thereby is suitable for practicality more.
Above-mentioned explanation only is the general introduction of the utility model technological scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.
