Abstract
The utility model discloses a kind of end cap of hydrodynamic retarder, comprise end cap body, one of this end cap body is throughly on the surface provided with multiple through hole, and multiple through hole is spaced apart along the edge of end cap body; The week of one end of described through hole, the week of one end of through hole, the week of one end of through hole was along being connected by inclined-plane with a surface of end cap body along being 1.5 ~ 3mm with the perpendicular distance on a surface of end cap body along the surface all protruding from end cap body.The utility model is easier to clear up iron filings.
Description
Technical field
The utility model relates to a kind of end cap of hydrodynamic retarder.
Background technique
Hydrodynamic retarder is a kind of auxiliary brake device for automobile, be mainly used in motorbus, urban public traffic vehicles, heavy truck and military vehicle, hydrodynamic retarder comprises housing, housing have shoe cream room and working oil chamber, impeller of rotor and stator impeller is provided with in working oil chamber, the output shaft of impeller of rotor and automotive transmission case is fixed together, and in motion, impeller of rotor also can rotate automobile.During hydrodynamic retarder work, pressurized air enters shoe cream room, oil pressure in shoe cream room is entered the cavity between stator impeller for hydrodynamic retarder and impeller of rotor, when hydrodynamic retarder is started working, impeller of rotor drives fluid to rotate about the axis, simultaneously, fluid moves along the direction blade of impeller of rotor and gets rid of to stator impeller, the blade of stator impeller produces reaction force to fluid, fluid outflow stator impeller goes back to impact rotor impeller again, so just form the resisting moment to impeller of rotor, impeller of rotor is made to produce braking torque, thus the decelerating effect realized vehicle.
The end cap of hydrodynamic retarder is mainly used in seal operation oil pocket, throughly on end cap be provided with multiple through hole, this end cap can be fixed by construction bolt in through hole, and the week edge of one end of through hole is surperficial lower than of end cap at present, that is the week edge of one end of through hole is positioned at the groove on a surface of end cap, like this, after end cap gets out through hole, in the groove of end cap, namely easily gather iron filings in the week of one end of through hole along place, this just requires a high expenditure of energy to clear up these iron filings, but also be not easy to clean out, make troubles to the manufacture of end cap.
Model utility content
Technical problem to be solved in the utility model is, provides a kind of end cap of hydrodynamic retarder, and it is easier to clear up iron filings.
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, one of this end cap body is throughly on the surface provided with multiple through hole, and multiple through hole is spaced apart along the edge of end cap body;
The week of one end of described through hole, the week of one end of through hole, the week of one end of through hole was along being connected by inclined-plane with a surface of end cap body along being 1.5 ~ 3mm with the perpendicular distance on a surface of end cap body along the surface all protruding from end cap body.
As preferably, the week of one end of described through hole is along being 2mm with the perpendicular distance on a surface of end cap body.
After adopting above structure, the utility model compared with prior art, has following advantage:
In the utility model, because the week of one end of described through hole is along the surface all protruding from end cap body, and the week of one end of through hole is along being connected by inclined-plane with a surface of end cap body, like this, after end cap body gets out through hole, iron filings accumulate on inclined-plane, because inclined convex is for a surface of end cap body, like this, with regard to being easy to, the iron filings on inclined-plane being cleared up, offering convenience to the manufacture of end cap.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A direction view in Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Shown in Fig. 1, Fig. 2, the end cap of the utility model hydrodynamic retarder comprises end cap body 1, one of this end cap body 1 is throughly on the surface provided with multiple through hole 101, and two surfaces of the through end cap body 1 of through hole 101, multiple through hole 101 is spaced apart along the edge of end cap body 1.
The week of one end of described through hole 101 is along the surface all protruding from end cap body 1, the week of one end of through hole 101 is along being 2mm with the perpendicular distance on a surface of end cap body 1, the week of one end of through hole 101 is along being connected by inclined-plane 102 with a surface of end cap body 1, inclined-plane 102 is circular, after end cap body 1 gets out through hole 101, iron filings accumulate on inclined-plane 102, because inclined-plane 102 protrudes from a surface of end cap body 1, like this, with regard to being easy to, the iron filings on inclined-plane 102 are cleared up.
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.
