Abstract
The utility model discloses a three-ball pin blind hole type universal joint finish forged tank casing which can move axially. As the essential transmission component of a passenger vehicle, a flange is arranged on the outer wall of the utility model, three sections of arc surfaces are evenly distributed in the inner hole of an inner cavity to form three ball paths, the inner cavity is closed at a flange end, the three ball paths of the inner cavity are blind holes, the flange is a circular structure, the closed end, the cavity wall and the flange are an integral structure, the inner cavity is closed at the flange end, to enable the three ball paths of the inner cavity to form blind hole ball paths. The utility model solves the problem that oil is leaked in the prior through hole type universal joint finish forged tank casing.
Description
Technical field
The utility model relates to the constant velocity universal joint finish forging pot shell that a kind of car drivetrain system is adopted, be specifically related to a kind of can axially movable three ball pin blind-hole type universal joint finish forging pot shells.
Background technique
Can axially movable tripod universal joint because of its complex structure, processing, detection difficulty are big, it has many excellent properties such as compact structure, in light weight, low noise, reliability height, freedom from repairs.At present, the transmission system of the whole world car overwhelming majority all adopts the transmission part of this universal joint as key.
The inner chamber of these product three ball pins is evenly distributed in the endoporus by three sections arc surfaces, so just formed three alleys 1 naturally in endoporus.Because of the operating characteristic of its product, so concentricity and alley indexing accuracy between each structure of inner chamber of three ball pins of this product are wanted high.Because of its structure uniqueness,, also meet the trend of world today's development of manufacturing simultaneously both at home and abroad so manufacturing firm all adopts inner chamber precision forging blank technology at present, can satisfy required precision like this, has reduced manufacture cost and cycle again.
As shown in Figure 1, existing three alleys 1 that can axially movable tripod universal joint inner chamber are through hole 2, thereby need pressure side lid at its flange 3 ends, in case leak-stopping oil.Because being pressed into of end cap be interference fit, link is and is rigidly connected, thereby still can produce leakage of oil in use, and assembly parts increased the production installation procedure, also is not easy to transportation.
Summary of the invention
Easily cause leakage of oil in order to overcome existing passing hole type structure that can axially movable tripod universal joint pot shell, influence the deficiency in working life, the purpose of this utility model is: provide a kind of can axially movable three ball pin blind-hole type universal joint finish forging pot shells, this three balls pin blind-hole type universal joint finish forging pot shell can make the universal joint product with compact structure, prevent leakage of oil, improve working life, and help making, install and transportation.
The technological scheme that its technical problem that solves the utility model adopts is as follows: a kind of can axially movable three ball pin blind-hole type universal joint finish forging pot shells, its outer wall one end is provided with flange, inner chamber is evenly distributed in the endoporus by three sections arc surfaces, form three alleys, described inner chamber seals at flange end, three alleys of inner chamber are blind hole, and described flange is a round structure, and this closed end and chamber wall and flange are overall structure.
The beneficial effects of the utility model are: realize integrated, the good airproof performance of product structure, increase product working life.Because three alleys of the utility model finish forging pot shell are blind hole, the flange end sealing forms overall structure, realize that product structure is integrated, thereby product hermeticity is good, has solved the leakage of oil problem of prior art, has increased the working life and the usability of product.
