Description
Technical field
The utility model relates to a kind of truck drive shaft, especially a kind of truck drive shaft seal closure.
Background technique
Truck drive shaft comprises the driving shaft and constant velocity universal joint that are connected, seal closure is established and is sealed between which, seal closure and driving shaft connecting part, and all only have one deck to seal with constant velocity universal joint housing connecting part, and clamped by collar, after long-time use, seal closure repeatedly deformation and impaired, especially just easily forms breakage in junction, makes it blow-by, volatilize in a large number will cause scrapping of truck drive shaft when interior oil like this, therefore must address this problem.
Summary of the invention
The technical problems to be solved in the utility model is: the truck drive shaft seal closure providing a kind of better tightness.
Scheme of the present utility model is:
A kind of truck drive shaft seal closure, comprise the cover body in accordion, the left end of cover body is little, right-hand member is large, longitudinal section is circular, described cover body left end is the tubular seals section matched with driving shaft, and described cover body right-hand member matches with constant velocity universal joint shell, and described cover body right-hand member has first and is sealed lip, be sealed inside lip first and be provided with circular step, the first longitudinal section being sealed lip is circular and first is sealed lip and exceeds described circular step to the right; Described cover body internal surface is also provided with arc scrobicular ring, and the spacing of arc scrobicular ring and circular step is at one centimetre to three centimetres.
Further improve as such scheme:
The outer surface of described cover body right-hand member is provided with the annular recess of at least one;
Described tubular seals section and the first internal surface being sealed lip are provided with sealing tooth;
Described circular step is provided with and is shorter than described first and is sealed second of lip and is sealed lip, and first is sealed the longitudinal section of lip also in circular;
Described tubular seals section has a reverse extension;
The beneficial effects of the utility model are:
Circular step can be fitted with constant velocity universal joint shell, and first is sealed lip and plays seal action, can improve sealing effect; The setting of arc scrobicular ring, be carry out direct collision in order to avoid in cover body movement process with constant velocity universal joint shell rim, can prevent cover body from being knocked against hard by constant velocity universal joint shell rim, thus guaranteeing its working life.

Embodiment
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
Embodiment 1:
As shown in Figure 1, truck drive shaft seal closure described by the present embodiment, comprise the cover body 1 in accordion, the left end of cover body 1 is little, right-hand member is large, longitudinal section is circular, described cover body 1 left end is the tubular seals section 2 matched with driving shaft 10, described cover body 1 right-hand member matches with constant velocity universal joint shell 11, it is characterized in that described cover body 1 right-hand member has first and is sealed lip 3, be sealed inside lip 3 first and be provided with circular step 4, the first longitudinal section being sealed lip 3 is circular and first is sealed lip 3 and exceeds described circular step 4 to the right; Described cover body 1 internal surface is also provided with arc scrobicular ring 5, and the spacing of arc scrobicular ring 5 and circular step 4 is at two centimetres.Wherein, the width of circular step 4 is first twices being sealed lip 3 thickness, can add heavy thickness like this, not cracky.
Truck drive shaft seal closure described by the present embodiment, its beneficial effect is: circular step 4 can be fitted with constant velocity universal joint shell 11, and first is sealed lip 3 and plays seal action, can improve sealing effect; The setting of arc scrobicular ring 5, be carry out direct collision in order to avoid in cover body 1 movement process with constant velocity universal joint shell rim, can prevent cover body 1 from being knocked against hard by constant velocity universal joint shell rim, thus guaranteeing its working life.
Embodiment 2:
As shown in Figure 2, the truck drive shaft seal closure described by the present embodiment, as different from Example 1: the outer surface of described cover body 1 right-hand member is provided with the annular recess 6 of two.
Seal closure is pressed on constant velocity universal joint shell by collar when installing, and can arrange projection at collar internal surface, and when press seal cover, projection can match with annular recess 6, is pressed into by seal closure in annular recess 6, such sealing effect is better.
Embodiment 3:
As shown in Figure 3, the truck drive shaft seal closure described by the present embodiment, as different from Example 2:
The internal surface of described tubular seals section 2 is provided with sealing tooth 7; Described circular step 4 is provided with and is shorter than described first and is sealed second of lip 3 and is sealed lip 8, and first is sealed the longitudinal section of lip 3 also in circular.
Second is sealed lip 8 can improve sealing further, formation be double-layer seal.
It should be noted that, driving shaft should be arranged and the groove sealing tooth 7 and match, to improve sealing.
Embodiment 4:
As shown in Figure 4, the truck drive shaft seal closure described by the present embodiment, as different from Example 3: described tubular seals section 2 has a reverse extension 9.
Reverse extension 9, together with tubular seals section 2, forms the sealing to driving shaft place, and their combination increases sealing surface greatly, useful to raising sealing effect.
