Abstract

The utility model relates to an independent oil baffle structure for an automobile oil sump, which is characterized in that a plurality of long holes are machined on both sides of the middle part of an arched oil baffle, and hammer-type holes are arranged among the long holes. The independent oil baffle structure has compact structure and reasonable design; on one hand, the arched oil baffle is independent of the oil sump, a crankcase is separated from the oil sump, therefore when the automobile runs on slope or brakes in emergency, or runs on bump road surfaces, the splashed oil is effectively closed in the oil sump, the crankshaft also revolves in the independent and closed space, and the crank throw of the crankshaft and the sliding and bubbling of the counterweight block are effectively prevented; on the other side, the rigidity of the oil baffle is increased through the arched structure and the reinforcement rib structure, the mechanical vibration of the oil baffle and the crankcase is effectively reduced, the intensity of the noise reaching oil sump from the crankcase is greatly reduced through the absorption and weakening of the opening structure, and the vibration and noise of the oil sump is also effectively reduced.

Description

Stand alone type automotive oil drain pan oil baffle structure

Technical field

The utility model relates to a kind of automotive oil drain pan stand alone type oil baffle structure.

Background technique

At present, usually adopt on the automotive oil drain pan oil baffle structure to prevent that crankshaft crank and balancing weight from buying oil and increase mechanical vibration and the noise that oil sump rigidity reduces oil sump.Because, during engine operation, the mechanical vibration of parts and noise pass to by cylinder body and make the oil sump position become one of the main vibrations of motor car engine and noise source in the thin-walled cavity of oil sump, if and the crankshaft crank counterweight foaming of buying oil, can influence the lubricated and cooling of motor, the functional reliability that threatens the hydraulic unit that utilizes engine oil pressure work simultaneously.

Traditional oil sump oil baffle generally is fixed in oil sump inside by the mode of welding or installation, on the one hand, when travelling on automobile or road surface of jolting during in climb and fall, Emergency braking, machine oil splashes in the oil sump, the crank throw of bent axle and balancing weight have the possibility of buying oil, causing machine oil to bubble influences the lubricated and cooling of motor, provides pressure to come the reliability of the hydraulic components of work also to constitute a threat to utilizing machine oil; On the other hand, mechanical vibration during engine operation and noise directly pass to the oil sump part of thin-walled by crankcase, and mechanical vibration and noise can not get effective reduction.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, and a kind of compact structure, reasonable in design is provided, and prevents that effectively crankshaft crank and balancing weight from buying oil, reducing the free-standing automotive oil drain pan oil baffle structure of oil sump vibrations and noise.

In order to achieve the above object, the technical solution adopted in the utility model is: have a plurality of slotted holes in both sides, arcuation oil baffle intermediate portion, also have the plektron hole between the slotted hole.

The utility model has the advantages that:

The utility model compact structure, reasonable in design, on the one hand, the arcuation oil baffle is independent of outside the oil sump, crankcase and oil sump are kept apart, therefore, when automobile at climb and fall with stop in emergency or jolting under the road traveling condition, the machine oil that splashes effectively is enclosed in the oil sump, and bent axle also turns round in the space of independent sealing, has effectively prevented the buy oil generation of foaming phenomenon of crankshaft crank and balancing weight; On the other hand, the arcuation structure of stand alone type oil baffle and the rigidity that reinforcing rib structure has strengthened oil baffle, can effectively reduce the mechanical vibration that self and crankcase transmit, the noise that crankcase transmits is through the absorption of open-celled structure and weaken, intensity reduces greatly when passing to oil sump, effectively reduces the vibration and the noise at oil sump position.

Fig. 2 is the right elevation of Fig. 1.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

By Fig. 1-Fig. 2 as can be known, the utility model has a plurality of slotted holes 2,4,7 in both sides, arcuation oil baffle 8 intermediate portion, also has plektron hole 5 between the slotted hole 4,7.

Described arcuation oil baffle 8 plate faces are provided with many stiffening ribs 1, the arcuation oil baffle about in the of 8 two-end part be located at flange 6, have a plurality of bolts hole 3 on the flange 6.

The utility model is arranged at free-standing oil baffle, the stand alone type oil baffle is installed between cylinder body and the oil sump by bolt, crankcase and oil sump are effectively kept apart, to crankcase acoustic noise reducing and absorption, and bent axle is turned round in the crankcase space of sealing, effectively avoid crank throw and balancing weight to buy oil.

On the one hand, the arcuation oil baffle is independent of outside the oil sump, crankcase and oil sump are kept apart, therefore, when automobile at climb and fall with stop in emergency or jolting under the road traveling condition, the machine oil that splashes effectively is enclosed in the oil sump, and bent axle also turns round in the space of independent sealing, has effectively prevented the buy oil generation of foaming phenomenon of crankshaft crank and balancing weight; On the other hand, the arcuation structure of stand alone type oil baffle and the rigidity that reinforcing rib structure has strengthened oil baffle, can effectively reduce the mechanical vibration that self and crankcase transmit, the noise that crankcase transmits is through the absorption of open-celled structure and weaken, intensity reduces greatly when passing to oil sump, effectively reduces the vibration and the noise at oil sump position.
