Description
Technical field
The utility model relates to auto parts and components field, particularly relates to the sliding universal joint of a kind of three ball pin.
Background technique
The high-performance constant velocity shaft assembly of passenger car is made up of fixed joint, sliding universal joint and the jack shaft be connected between universal joint usually.Sliding universal joint comprises three ball pin style and six bead, use the sliding universal joint of three ball pins more in the market, it comprises outer race and is set in three ball pin assemblies in outer race, three ball pin assemblies can slippage in outer race, three ball pin assemblies comprise spider, spider is evenly provided with three bearing pins, bearing pin is all arranged with roller, needle roller, catch and snap ring, the two ends of needle roller by catch and snap ring spacing, this construction cost is low, structure is simple, lightweight, but because roller is also limited while needle roller is by retainer ring spacing, roller slippage is little, pivot angle is little, so back-up ring, needle roller easily comes off or damages, clamping stagnation is there is in running, oscillation phenomenon, and existing three ball pin frictions are larger, overall transmission efficiency is lower.
Summary of the invention
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provides the sliding universal joint of three ball pins that a kind of internal friction is little, ball assembly slippage large, adjustable, the overall transmission efficiency of work pivot angle is high, operational shock is little.
For achieving the above object, technical solution of the present utility model is: the sliding universal joint of a kind of three ball pin, and it comprises sliding sleeve and is set in three ball pin assemblies in sliding sleeve; The chute for three ball pin assembly slippages is provided with in described sliding sleeve; Three ball pin assemblies comprise centre and are provided with roller assembly sheathed on three bearing pins and each bearing pin that the spider of spline, spider are evenly arranged; The cross section of each bearing pin and spider transition position is oval; Described roller assembly comprises outer roller, internal trolley and multiple needle roller; Described internal trolley inwall and bearing pin sidewall match, and are set on bearing pin; The face that described bearing pin contacts with described internal trolley inwall is sphere; Chute in outer roller outer wall and sliding sleeve matches, and it is set in the chute in sliding sleeve; Described internal trolley outer wall inside and outside two ends has annular protrusion A and annular protrusion B respectively, and described needle roller is arranged in the needle roller mounting groove that annular protrusion A and annular protrusion B forms; Described outer roller inwall outer end is provided with draw-in groove, is provided with spacing back-up ring, prevents needle roller from coming off in described draw-in groove.
Each bearing pin longitudinal section described above catercorner length is less than or equal to the length of described bearing pin geometrical center place cross-sectional diameter.Length due to the cornerwise length in bearing pin longitudinal section and bearing pin cross-sectional diameter is the extreme value of bearing pin surface any two points spacing, ensure that the wire length of any two point of contact of bearing pin and internal trolley is necessarily less than or equal to the diameter of bearing pin cross section so arrange like this, when bearing pin and roller adjust work pivot angle in the scope limited, bearing pin can match with internal trolley always.
Each bearing pin described above and spider transition position are the arc of indent, and during to ensure adjustment roller assembly pivot angle, the lower end of outer roller can coordinate with the arc concave shape of joint thus improve the pivot angle scope of roller assembly.
The external diameter of internal trolley outer end annular protrusion described above is less than the internal diameter of described spacing back-up ring, and internal trolley can be slided by the inwall of needle roller along described outer roller, to increase slippage.
Outer roller inwall inner end described above is provided with annular protrusion C, and the transition position of annular protrusion C and outer roller inwall is the arc of indent; The internal diameter of described annular protrusion C is less than the external diameter of described internal trolley inner end annular protrusion A, and to make outer roller come off, described outer roller can be rolled around internal trolley by needle roller.
Sliding sleeve described above passes through cold extrusion forming, the chute of described sliding sleeve all has two cross sections be arc guiding shoulder, relative to arrange in the middle part of chute single guide shoulder to be arranged so that ball adjustment operating angle like this time with guide the contact of take on more soft, the vibration in running can obviously reduction.
The utility model adopts three ball pin assemblies, has the advantage that internal friction is little, roller assembly slippage large, adjustable, the overall transmission efficiency of work pivot angle is high, operational shock is little.Needle roller is arranged in the needle roller mounting groove that annular protrusion A and annular protrusion B forms, and needle roller is relatively short, and outer ring does not have the mounting groove of needle roller, it is easily processed, and outer wall also can not be thinning, long service life.
