Abstract
The utility model discloses a kind of end cap of hydrodynamic retarder, comprise end cap body, end cap body is provided with a boss, boss is provided with an axis hole, the side of boss is provided with one around axis hole for the anchor ring arranging oil sealing; Described anchor ring is provided with multiple groove.The utility model weight saving, and the generation that can reduce pore and husky hole on anchor ring when casting.
Description
Technical field
The utility model relates to a kind of end cap of hydrodynamic retarder.
Background technique
Hydrodynamic retarder is a kind of complemental brake system, and automobile, when deceleration or lower long slope, enables hydrodynamic retarder, passable
Steady deceleration, can reduce brake frequency of utilization, is a good complemental brake system, is generally arranged on gearbox rear end concerning automobile.As shown in Figure 1, in prior art hydrodynamic retarder end cap on be provided with boss 01, boss 01 is provided with an axis hole 02, the side of boss 01 is provided with one around axis hole 02 for the anchor ring 03 arranging oil sealing, when installing hydrodynamic retarder, anchor ring 03 is for arranging oil sealing, the radial width of current anchor ring 03 is comparatively large, making the wall thickness of boss 01 comparatively large, making when casting this end cap, easily on anchor ring, produce pore and husky hole, and the heavier-weight of this end cap.
Model utility content
Technical problem to be solved in the utility model is, provides a kind of end cap of hydrodynamic retarder, its weight saving, and can reduce the generation in pore and husky hole on anchor ring when casting.
For solving the problems of the technologies described above, the end cap of the hydrodynamic retarder that the utility model provides, comprising:
End cap body, end cap body is provided with a boss, boss is provided with an axis hole, and the side of boss is provided with one around axis hole for the anchor ring arranging oil sealing;
Described anchor ring is provided with multiple groove.
As preferably, described groove is arc groove, and multiple arc groove all extends along the circumferential direction arc of anchor ring, and multiple arc groove intervals are arranged.
As preferably, the opposite side of described boss is active chamber wall, and active chamber wall is curved along the radial direction of axis hole, and the bottom of arc groove parallels with active chamber wall.
After adopting above structure, the utility model compared with prior art, has following advantage:
In the utility model, anchor ring arranges arc groove, alleviate the weight of this end cap, and owing to being provided with arc groove on anchor ring, making, when casting this end cap, to add the mobility of the raw material being cast as anchor ring, the generation in pore and husky hole on anchor ring after increasing mobility, can be reduced.
Accompanying drawing explanation
Fig. 1 is the structural representation of the end cap of hydrodynamic retarder in prior art;
Fig. 2 is the structural representation of the end cap of hydrodynamic retarder in the utility model;
Fig. 3 is the sectional drawing of the end cap of hydrodynamic retarder in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Shown in Fig. 2, Fig. 3, the end cap of the utility model hydrodynamic retarder comprises end cap body 1, end cap body 1 is provided with a boss 101, boss 101 is provided with an axis hole 102, the side of boss 101 is provided with one around axis hole 102 for the anchor ring 103 arranging oil sealing, and when installing hydrodynamic retarder, rotatingshaft is located on axis hole 102, oil sealing is arranged on anchor ring 103, spills from axis hole 102 to avoid the oil in the active chamber of hydrodynamic retarder.
Described anchor ring 103 is provided with multiple groove, and described groove is arc groove 104, and multiple arc groove 104 all extends along the circumferential direction arc of anchor ring 103, and multiple arc groove 104 interval is arranged, and multiple arc groove 104 circumference is spaced apart.
Anchor ring 103 arranges arc groove 104, alleviate the weight of this end cap, and owing to being provided with arc groove 104 on anchor ring 103, make when casting this end cap, add the mobility of the raw material being cast as anchor ring 103, the generation in pore and husky hole on anchor ring 103 after increasing mobility, can be reduced.
The opposite side of described boss 101 is active chamber wall 105, active chamber wall 105 is curved along the radial direction of axis hole 102, the bottom of arc groove 104 parallels with active chamber wall 105, that is the bottom of arc groove 104 is the shape matched with active chamber wall 105, the degree of depth of arc groove 104 can be increased like this, to alleviate the weight of this end cap to greatest extent.
Below only apply preferably example with regard to the utility model and made explanation, but can not be interpreted as it is limitations on claims, structure of the present utility model can have other to change, and is not limited to said structure.In a word, all various changes done in the protection domain of independent claims of the present utility model are all in protection domain of the present utility model.
