Abstract
The invention discloses an automobile synchronizing ring. The automobile synchronizing ring comprises a synchronizing ring body (1), wherein an internal conical surface of the synchronizing ring body (1) is provided with a screw thread (6); three positioning lugs (3) and three sliding block pushing and stopping blocks (4) are correspondingly arranged on the synchronizing ring body (1); gear teeth (2) area are arranged in every two adjacent positioning lug (3) and two adjacent sliding block pushing and stopping block (4); the synchronizing ring body (1) is provided with a sliding block limiting step groove (5); the sliding block limiting step groove (5) is positioned at the bottoms of the sliding block pushing and stopping blocks (4); and the sliding block limiting step groove (5) and the sliding block pushing and stopping blocks (4) are in centrally symmetrical. According to the automobile synchronizing ring provided by the invention, low-carbon alloy steel with high quality and low price is used for replacing expensive copper alloy to manufacture the automobile synchronizing ring, a friction surface is made of molybdenum material, and the automobile synchronizing ring has obvious technical economical advantages of being low in material cost, high in material utilization ratio, high in product geometric accuracy and long in service life and the like.
Description
Technical field
The present invention relates to a kind of automotive synchronizing ring.
Background technique
Along with the manufacturing fast development of domestic automobile, the high speed development of Medium or severe type automobile and motor bus particularly, the introduction of advanced foreign technology, medium-heavy automobile is extended and expansion towards many gears, large-tonnage, high-quality direction, and Medium or severe type automobile synchronizer technology and technological level also improve constantly thereupon and upgrade.The base steel sprayed molybdenum synchronizing ring that represents external advanced technologies technical quality level has been developed utilization in American-European, Japan, and the synchronizing ring that China's Medium or severe type automobile and motor bus use is stuck on the level of production of Cuprum alloy mostly.Synchronizing ring is used for automobile running balance speed-change and gearshift as the vital part of automobile gearbox, handles light and flexible, and its dimensional accuracy and application structure feature have very important impact to the performance of car load.
Summary of the invention
The invention provides a kind of automotive synchronizing ring, low-carbon alloy steel with super quality and competitive price replaces expensive Cuprum alloy to make automotive synchronizing ring, Mo is made rubbing surface, combine the advantage of Precision Forming Technology and sprayed molybdenum technology, have that the cost of material is low, stock utilization is high, and the product geometric accuracy is high, the significant technological and economical advantages such as long service life.
The present invention has adopted following technological scheme: a kind of automotive synchronizing ring, comprise the synchronizing ring main body, the inner conical surface of described synchronizing ring main body is provided with screw thread, correspondence is provided with three locating lugs and three slide block thrust blocks on the synchronizing ring main body, is provided with the gear teeth between adjacent two locating lugs and slide block thrust block; It is characterized in that described synchronizing ring main body is provided with the spacing step trough of slide block, the spacing step trough of described slide block is positioned at the bottom of slide block thrust block, both Central Symmetries.
The described screw thread side of being dental structure, pitch is 2mm; Described thread surface is provided with molybdenum layer, molybdenum layer thickness 0.7～0.8mm; The spacing step trough of described slide block is semicircular arc hierarchic structure; Described synchronizing ring main body is the alloyed steel structure; Be provided with six gear teeth between described adjacent two locating lugs and the slide block thrust block.
The present invention has following beneficial effect: automotive synchronizing ring of the present invention is set up the spacing step trough structure of slide block in slide block thrust block position, when the synchronizer shift slide block is moved by axial force, upper end of slide block face and slide block thrust block are fitted, slide block lower end surface and the large cylindrical of T-shaped positioning block are interfered by spacing the avoiding of the spacing step trough control of slide block, the synchronizing ring inner conical surface screw thread side of employing dental structure, thread surface is provided with molybdenum layer, not only being conducive to improve friction torque keeps rubbing surface wear-resistant simultaneously, low-carbon alloy steel with super quality and competitive price replaces expensive Cuprum alloy to make automotive synchronizing ring, Mo is made rubbing surface, combine the advantage of Precision Forming Technology and sprayed molybdenum technology, have that the cost of material is low, stock utilization is high, and the product geometric accuracy is high, the significant technological and economical advantages such as long service life.
