Abstract
The utility model relates to a lower oil pan assembly which is simple in structure, capable of enhancing the strength of a lower oil pan, and not prone to deformation. The lower oil pan assembly is arranged on the lower portion of an engine and comprises a body. The body comprises a combination surface locked on the lower portion of the engine and a storage chamber which protrudes towards the side far away from the engine. The surface which is on the periphery side of the storage chamber and is connected with the inner edge of the combination surface is provided with a plurality of folds in a stamped mode so as to enhance the strength of the storage chamber. The surface which is on the storage chamber and is not connected with the inner edge of the combination surface is provided with reinforcing grooves in a stamped mode. The reinforcing grooves are of an X shape or a strip shape.
Description
Technical field
The utility model relates to a kind of lower oil pan assembly.
Background technique
Lower oil sump is generally positioned at engine engine bottom, and the shell using crankcase seals as oil storage tank.Main Function is to prevent that impurity from entering, and collects and store the lubricant oil being flowed back to by each friction surface of motor, and the part that leaves heat, prevents oil ageing.Its structure shape is different, depends primarily on the space of engine compartment.Some engine compartment limited space and irregular will be dodged the various component in engine compartment simultaneously, causes the shape of lower oil sump special-shaped especially, the special limit, and this just has higher requirement to extra-deep drawing drawing work.
Low carbon steel, because its intensity is low, hardness is low and soft, therefore claim again mild steel, is scarcely used for engineering structure part through heat treatment.It is usually used as the first-selection of lower oil sump, but it can not have large-area smooth flat or curved surface again, otherwise easily caves in, thereby reduces the volume space of lower oil sump, thereby makes the oil mass holding be less than the value of holding of appraising and deciding, and causes easy leakage of oil.
Summary of the invention
Therefore,, for above-mentioned problem, the utility model proposes a kind of simple in structure, intensity that can strengthen lower oil sump, on-deformable lower oil pan assembly.
For achieving the above object, the utility model has adopted following technological scheme: a kind of lower oil pan assembly, it is located at engine engine bottom, comprise body, described body comprises the junction plane that is locked in engine engine bottom, to the room that holds away from engine engine one side projection, described all sides that hold room and be provided with a plurality of fold with junction plane interior along the mode by punching press on the face being connected and hold the intensity of room with enhancing, described hold on room and with junction plane in along on disjunct respectively the mode by punching press be provided with strengthening groove, described strengthening groove is X-shaped strengthening groove or bar shaped strengthening groove.
Further, the outer of described junction plane convexes to form to the side away from holding room the convex edge that prevents oil spilling, and described junction plane is inwardly downward-sloping gradually along outer, and angle of inclination is 5～10 °.
By adopting aforementioned techniques scheme, the beneficial effects of the utility model are: compare with existing lower oil sump, this lower oil sump holds all sides of room and along the mode by punching press on the face being connected, is provided with a plurality of fold to strengthen the intensity that holds room with the interior of junction plane, make it not yielding, described hold on room and with junction plane in along on disjunct respectively the mode by punching press be provided with strengthening groove, make it not yielding; Further, the outer of described junction plane convexes to form to the side away from holding room the convex edge that prevents oil spilling, and described junction plane is inwardly downward-sloping gradually along outer, can increase oil reserve, more practical.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is worm's eye view of the present utility model.
Fig. 3 is the schematic cross-section at A-A place in Fig. 2.
Embodiment
Now with embodiment, the utility model is further illustrated by reference to the accompanying drawings.
With reference to figure 1, Fig. 2, Fig. 3, the present embodiment provides a kind of lower oil pan assembly, it is located at engine engine bottom, comprise body, described body comprise be locked in the junction plane 1 of engine engine bottom, to holding room 2 away from engine engine one side projection, on described junction plane 1, be arranged at intervals with a plurality of attachment holes that are connected with engine engine 11, between described each adjacent attachment hole 11, be provided with bar shaped oil spilling groove 12.Described all sides that hold room 2 and be provided with a plurality of fold 21 to strengthen the intensity that holds room 2 with the mode by punching press on the interior face being connected along 1a of junction plane 1, described hold on room 2 and with junction plane 1 interior along on disjunct of 1a respectively the mode by punching press be provided with strengthening groove 22, wherein two strengthening grooves 22 are X-shaped strengthening groove, and a strengthening groove 22 is bar shaped strengthening groove.
The outer 1b of described junction plane 1 convexes to form the convex edge 13 that prevents oil spilling to the side away from holding room 2, described junction plane 1 is inwardly downward-sloping gradually along outer 1b, and its inclined angle alpha is 10 °.Wherein inclined angle alpha is preferred value, and it can be also any number between 5～10 °.
Compare with existing lower oil sump, this lower oil sump holds all sides of room and along the mode by punching press on the face being connected, is provided with a plurality of fold to strengthen the intensity that holds room with the interior of junction plane, make it not yielding, described hold on room and with junction plane in along on disjunct respectively the mode by punching press be provided with strengthening groove, make it not yielding; Further, the outer of described junction plane convexes to form to the side away from holding room the convex edge that prevents oil spilling, and described junction plane is inwardly downward-sloping gradually along outer, can increase oil reserve, more practical.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but those skilled in the art should be understood that; within not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
