Abstract
The utility model provides a sealing structure of a ball stud and a dust cover, which includes a front shaft swing arm ball pin seat, a ball head leather cup, a ball head pin, a clamp hoop and a dust cover, wherein the dust cover is covered outside a pin neck part and a pin rod part of the ball head pin; a ring of spacing boss is arranged on or above a conical surface section of the pin rod part of the ball head pin; a ring of annular framework with an L-shaped cross section is arranged on the inner ring of a dust cover upper hole; the dust cover upper hole is sleeved on the pin rod part; and the dust cover upper hole is spaced through the matching of the overturned edge of the annular framework and the spacing boss. Through the spacing boss additionally arranged on the ball head pin and the annular framework additionally arranged in the dust cover upper hole, the ball head and the ball head leather cup are sealed against water and silt. The sealing structure of the ball stud and the dust cover has a simple and reasonable structure, is easy to manufacture, is favorable for protecting the ball head and the ball head leather cup against water and silt, improves the performance of the ball pin and the dust cover, and prolongs the service life of the front shaft swing arm assembly.
Description
Technical field
The utility model relates to mechanical sealing technology, is specifically related to the sealing configuration of ball stud and dust-proof cover in the automobile front axle swing arm assembly.
Background technique
As shown in Figure 1; In the existing automobile front axle swing arm assembly; Ball stud is to adopt the conical surface of ball stud 3 to cooperate with the last hole of dust-proof cover 5 with the sealing configuration of dust-proof cover, and the means of fixation of the following hole of dust-proof cover and front axle swing arm ball key seat 1 is that clip 4 is tightened, and its major defect is that ball stud is with in wheel and the bob process; The hole moves up and down with respect to the ball stud conical surface and swings on the dust-proof cover; Dust-proof cover receives flexural oscillations and variation of ambient temperature and harmful liquid corrosion effect for a long time, has increased hole and the conical surface section of ball stud and the fit up gap of pin neck (the pin neck is realized transition through conical surface section and pin rod portion under pin rod portion) on the dust-proof cover; To water and silt are got in the bulb leather cup; Quickened the wearing and tearing of bulb in bulb leather cup 2, caused serious problems such as the bulb pine is spacious, hair fastener, abnormal sound, hard steering inefficacy, this all can bring potential safety hazard to driving.
The model utility content
The purpose of the utility model provides and a kind ofly can overcome the above-mentioned defective of existing in prior technology, reasonable in design, a kind of ball stud that does not influence front axle swing arm assembly appearance and modeling and the sealing configuration of dust-proof cover.
The utility model technological scheme is following:
The sealing configuration of a kind of ball stud and dust-proof cover, it comprises front axle swing arm ball key seat, bulb leather cup, ball stud, clip, dust-proof cover; The ball head of said ball stud is divided in the bulb leather cup of front axle swing arm ball key seat; Dust-proof cover is enclosed within outside the pin neck and pin rod portion of ball stud, and the following hole of dust-proof cover is connected with front axle swing arm ball key seat and fixes through clip.The position is provided with a circle positive stop lug boss on the conical surface section of the pin rod portion of said ball stud or conical surface section; On said dust-proof cover the inner ring in hole be provided with one the circle section be the ring skeleton of L type; The last borehole jack of said dust-proof cover is in pin rod portion, and the flange through ring skeleton cooperates with positive stop lug boss and carries out spacing to the last hole of dust-proof cover.
Compared with prior art; When the ball stud axis moved downward, ball stud did not have limit structure in the conical surface section of pin rod portion to the utility model to hole on the original dust-proof cover, and Kong Yi falls into the less pin neck position of size on the dust-proof cover; To make can not waterproof and dustproof etc. problem; Through the positive stop lug boss that on ball stud, increases, the ring skeleton that increases in the hole on the dust-proof cover plays the effect that does not get into water and silt in sealing bulb and the bulb leather cup.The utility model is simple and reasonable, and is easy to manufacture, helps protecting bulb and bulb leather cup not by the entering of water and silt, improves the performance of ball stud and dust-proof cover, prolonged the working life of front axle swing arm assembly.
Description of drawings
Accompanying drawing 1 is the sealing configuration of original ball stud and dust-proof cover.
Accompanying drawing 2 is the ball stud of the utility model and the sealing configuration of dust-proof cover.
Among the figure: 1-front axle swing arm ball key seat, 2-bulb leather cup, 3-ball stud, 4-clip, 5-dust-proof cover, 6-positive stop lug boss, 7-ring skeleton, 8-knuckle, 9-bolt, 10-nut.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is done further explain;
Referring to Fig. 2, the ball head of ball stud 3 is divided in the bulb leather cup 2 of front axle swing arm ball key seat 1, and the upper end of the pin rod portion of ball stud 3 is passed the swing arm locking hole of knuckle 8 and is locked by bolt 9 and nut 10.Dust-proof cover 5 is enclosed within outside the pin neck and pin rod portion of ball stud 3, and the following hole of dust-proof cover 5 is connected with front axle swing arm ball key seat 1 and is fixing through clip 4.The sealing configuration of ball stud and dust-proof cover is that a circle positive stop lug boss 6 is established in position on the conical surface section of the pin rod portion of ball stud 3 (or conical surface section); On dust-proof cover 5 inner ring in hole establish one the circle section be the ring skeleton 7 of L type; With the last borehole jack of dust-proof cover 5 conical surface section, cooperate with positive stop lug boss 6 on the conical surface section through the flange of ring skeleton 7 and to carry out spacing the last hole of dust-proof cover 5 in pin rod portion.
In vehicle traveling process; Move up and down with respect to the conical surface section of ball stud 3 and swing with the ring skeleton 7 in the last hole of the rotation of wheel and bob process dust-proof cover 5; Positive stop lug boss 6 on this moment conical surface section cooperates with the flange in the ring skeleton 7; Controlled effectively that Kong Yi falls into the less pin neck position of size on the dust-proof cover 5, prevented the entering of water and silt etc. effectively, improved the sealability of ball stud and dust-proof cover; Serious problems such as motion hair fastener, abnormal sound, the pine of the bulb position that has solved ball stud 3 in bulb leather cup 2 is spacious have improved the driving safety performance.
