Description
Technical field
The utility model relates to hydrodynamic retarder technical field, specifically refers to a kind of hydrodynamic retarder grease chamber housing.
Background technique
For the downhill retardation of heavy truck, lorry, slow down usually through automobile braking safety auxiliary device, the core component of this device is hydraulic buffer, heavy truck, the lorry main shaft speed of a motor vehicle can be made to reduce, thus reach the object of downhill retardation by this hydraulic buffer.
At present, the active chamber housing that the housing of comparatively common hydrodynamic retarder mainly comprises grease chamber's housing, is installed on the end cap of grease chamber's shell one end, is installed on grease chamber's housing the other end, wherein active chamber housing is divided into left and right two halves, half is arranged on grease chamber's shell end and one-body molded with grease chamber's housing, for active chamber housing parts integrated with grease chamber's housing, in industry, custom is referred to as active chamber left shell, and second half installation separately then becomes active chamber right shell body.
At present, for grease chamber's housing of above structure, the position be connected with grease chamber's shell body at active chamber left shell connects mainly through arc transition, but the straight outer wall protruding arc-shaped transitional surface is provided with at oil-hole location place, after the straight outer wall of this evagination is arranged, overall span is larger, the position wall thickness on the one hand active chamber left shell being connected with grease chamber's shell body increases, cause active chamber left shell and grease chamber's shell body connection part integral wall thickness ununiformity even, then easily casting defect is there is like this when casting, reduce the castability of product, the straight outer wall overall weight weight of evagination on the other hand, add the gross weight of whole grease chamber housing virtually, and needed raw material is more, the object of province's material cannot be reached.
Model utility content
The technical problems to be solved in the utility model is, provides one effectively can reduce oilhole place wall thickness, and can alleviate overall weight, reaches the hydrodynamic retarder grease chamber housing of province's material object.
For solving the problems of the technologies described above, the technological scheme that the utility model provides is: comprise grease chamber's shell body, be located at grease chamber's shell body end and active chamber left shell integrated with grease chamber's shell body, arc transition connecting wall is provided with between described active chamber left shell and grease chamber's shell body, this arc transition connecting wall offers oilhole, described oilhole protrudes to arc transition connecting wall outside and forms oil duct, the arc transition connecting wall of described oilhole upper and lower sides is also provided with the reinforcement gusset protruded to arc transition connecting wall outside.
Described stiffening rib slab integral is semicircle tabular, and outer end keeps flushing with active chamber left shell outer side wall.
Also be provided with short reinforcement gusset on the left of described oilhole, this short reinforcement gusset is crossing with oil duct outer wall vertical.
Oilhole is directly arranged on the arc transition connecting wall between active chamber left shell and grease chamber's shell body by hydrodynamic retarder grease chamber of the present utility model housing, that is the straight outer wall eliminating evagination of the prior art is equivalent to, effective like this weight alleviating whole grease chamber housing, eliminate a large amount of raw material, the more important thing is that the arc transition connecting wall wall thickness hinge structure making oilhole place is effectively thinning, maintain the even of whole arc transition connecting wall wall thickness, avoid because of wall unevenness or blocked up and casting defect that is that produce, improve the castability of product.In addition, the setting of the oil duct of evagination, adds the intensity of whole oilhole, is also convenient to the equipped of the miscellaneous part docked with oilhole, and strengthens the setting of gusset, compensate for the intensity of the arc transition connecting wall at oilhole place.
Further, described stiffening rib slab integral is semicircle tabular, and outer end keeps flushing with active chamber left shell outer side wall, and the casting of semicircle tabular is simple, and intensity is good, and keeps flushing to prevent when being equipped with miscellaneous part interfering phenomenon.
Further, be also provided with short reinforcement gusset on the left of described oilhole, this short reinforcement gusset is crossing with oil duct outer wall vertical, adds the intensity of oil duct.
Accompanying drawing explanation
Accompanying drawing is the structural representation of the utility model hydrodynamic retarder grease chamber housing.
Shown in the utility model figure: 1 grease chamber's shell body, 2 active chamber left shells, 3 arc transition connecting walls, 4 oil ducts, 5 strengthen gusset, 6 short reinforcement gussets.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, hydrodynamic retarder grease chamber of the present utility model housing, comprise grease chamber's shell body 1, be located at shell body 1 end, grease chamber and active chamber left shell 2 integrated with grease chamber's shell body 1, namely active chamber left shell 2 and grease chamber's shell body 1 are integral type structure, simultaneously casting.
Complete arc transition connecting wall 3 is provided with between described active chamber left shell 2 and grease chamber's shell body 1, this arc transition connecting wall 3 directly offers oilhole (unmarked), described oilhole protrudes to arc transition connecting wall 3 outside and forms oil duct 4, namely the cylindrical body in hollow, this cylindrical center hole and oilhole are coaxially set.
The arc transition connecting wall 3 of described oilhole upper and lower sides is also provided with the reinforcement gusset 5 protruded to arc transition connecting wall 3 outside, after this reinforcement gusset is arranged, the intensity of the arc transition connecting wall at oilhole place can be increased.
As the improvement project of the present embodiment, described reinforcement gusset 5 entirety is in semicircle tabular, and outer end keeps flushing with active chamber left shell 2 outer side wall, such outer end keeps the reinforcement gusset flushed when grease chamber's housing and miscellaneous part are equipped with, interference when just can not protrude active chamber left shell and cause equipped.
In addition, for increasing the intensity of oil duct 4, short reinforcement gusset 6 is also provided with on the left of described oilhole, this short reinforcement gusset 6 is crossing with the outer wall vertical on the left of oil duct 4, and in the present embodiment, outer wall on the right side of described oil duct 4 is also connected with the diapire of active chamber left shell 2, so also can increase the intensity of oil duct.
Hydrodynamic retarder grease chamber of the present utility model housing, by arranging complete arc transition connecting wall, and oilhole is directly set on this arc transition connecting wall, so just eliminate the straight outer wall of evagination in prior art, significantly reduce the weight of grease chamber's housing, save raw material, reach the object of province's material, make the wall thickness reduction at oilhole place simultaneously, maintain the even of the integral thickness of whole arc transition connecting wall, ensured castability.
