Abstract
The utility model discloses a disk claw type middle ring for a gear box synchronizer, which comprises a conical ring body and a protruding claw, wherein the conical ring body comprises an outer conical surface and an inner conical surface; the inner conical surface is provided with the protruding claw; sunk platforms are arranged at the bottoms of the two sides of the protruding claw; and the sunk platforms have transition with the protruding claw by a circular arc surface. The design that the sunk platforms have transition with the protruding claw by the circular arc surface effectively reduces stress concentration, thereby increasing the service life of the products of the disk claw type middle ring for the gear box synchronizer.
Description
Technical field
The utility model relates to the assembly in a kind of synchronizer, particularly relates to a kind of dish pawl formula central ring that is used for Synchromous device of gearbox.
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, traditional 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.
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 dish pawl formula central ring that is used for Synchromous device of gearbox of new structure, technical problem to be solved are provided is to make its generation that effectively reduces disconnected pawl phenomenon, the working life of improving this product; 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.The dish pawl formula central ring that is used for Synchromous device of gearbox according to the utility model proposition; Comprise conical ring body and dog; Said conical ring body comprises male cone (strobilus masculinus) and inner conical surface; Said inner conical surface is provided with dog, and the bottom of said dog both sides is provided with heavy stand, and said heavy stand and said dog are through the arc surface transition.
The aforesaid dish pawl formula central ring that is used for Synchromous device of gearbox, wherein, the length of said dog is 8-8.3mm, wide is 4mm.
The aforesaid dish pawl formula central ring that is used for Synchromous device of gearbox, wherein, said heavy stand and said dog are the arc surface transition of 0.8mm through radius.
By technique scheme, the dish pawl formula central ring that the utility model is used for Synchromous device of gearbox has advantage at least:
Heavy stand and dog have effectively reduced concentrating of stress through the design of arc surface transition, and then the life-span of having improved the utility model product.
In sum, the dish pawl formula central ring that is used for Synchromous device of gearbox 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.
Description of drawings
Fig. 1 is the described dish pawl formula central ring plan view that is used for Synchromous device of gearbox of the utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined model utility purpose is taked, below in conjunction with accompanying drawing and preferred embodiment, to the embodiment of the utility model specify as after.
As depicted in figs. 1 and 2, be used for the dish pawl formula central ring of Synchromous device of gearbox, comprise conical ring body and dog; The conical ring body comprises male cone (strobilus masculinus) 3 and inner conical surface 1, evenly is provided with three dogs 2 on the inner conical surface 1, and the length of dog 2 is 8.3mm; Wide is 4mm, and the bottom of dog 2 both sides is provided with heavy stand 4, and heavy stand 4 is the arc surface transition of 0.8mm through radius with dog 2; Effectively reduced concentrating of stress, and then the life-span of having improved the utility model product.
The above; It only is the preferred embodiment of the utility model; Not being that the utility model is done any pro forma restriction, though the utility model with the preferred embodiment exposure as above, yet is not in order to limit the utility model; Anyly be familiar with the professional and technical personnel; In not breaking away from the utility model technological scheme scope, make a little change or be modified to the equivalent embodiment of equivalent variations when the technology contents of above-mentioned announcement capable of using, be the content that does not break away from the utility model technological scheme in every case;, all still belong in the scope of the utility model technological scheme any simple modification, equivalent variations and modification that above embodiment did according to the technical spirit of the utility model.
