Description

Reinforcing rib structure of oil pan

Technical Field

The utility model relates to the technical field of engine accessories, in particular to a reinforcing rib structure of an oil pan.

Background

The oil sump is the lower half part of the engine crankcase, also called the lower crankcase, and is a shell which closes the crankcase and is used as an oil storage tank to prevent impurities from entering, collect and store lubricating oil flowing back from each friction surface of the engine, dissipate part of heat and prevent the lubricating oil from being oxidized. As the demand for ride comfort of automobiles increases, the NVH characteristics of automobile engines become more of a concern to host factories. NVH is an english abbreviation for Noise, Vibration and Harshness (Noise, Vibration, Harshness), a comprehensive problem of measuring the quality of manufactured automobiles, which gives the users of automobiles the impression of being most immediate and superficial. For the oil pan, generally, the measure of reducing sound source vibration or reducing sound energy is often adopted to reduce mechanical noise, and in order to achieve the effects of high strength and high mode, the thickness of the oil pan is mostly increased, but the weight of the oil pan is increased, and the cost is increased. Therefore, designers think of the mode and the structural strength of the oil pan which are increased by the reinforcing ribs on the bottom position of the inner cavity of the oil pan to avoid resonance and resonance, but the reinforcing ribs arranged on the bottom position of the inner cavity of the oil pan separate the bottom of the oil pan into a plurality of areas, and the upper surface of the reinforcing ribs protrudes out of the bottom wall of the oil pan.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a reinforcing rib structure of an oil pan, which can meet the requirements of modes and strength and can completely discharge engine oil.

In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides a strengthening rib structure of oil pan, includes the oil pan body, the bottom position department of oil pan body inner chamber is provided with deep floor and separates the bottom cavity, and the oil drain has been seted up to oil pan body bottom and lateral wall juncture, deep floor close to bottom position department and set up the via hole of intercommunication both sides cavity.

In the above scheme, deep floor separates the oil sump of oil pan body bottom, has improved the intensity and the mode of oil pan, punches simultaneously in deep floor bottom, and the machine oil in the different oil sumps can circulate each other for the oil pan oil drain is smooth and easy and be favorable to reducing oil pan bottom machine oil and remain when the maintenance.

Detailed Description

As shown in fig. 1 and 2, the reinforcing rib structure of the oil pan comprises an oil pan body 10, a reinforcing rib plate 11 is arranged at the bottom of an inner cavity of the oil pan body 10 to separate a bottom cavity, an oil drain hole 12 is formed at the junction of the bottom and a side wall of the oil pan body 10, and a through hole 111 communicating the cavities on two sides is formed at the position, close to the bottom, of the reinforcing rib plate 11. Set up deep floor 11 in the bottom of oil pan body 10 inner chamber and separate the oil bath of oil pan body 10 bottom, improved the intensity and the mode of oil pan, punch in deep floor 11 bottom simultaneously, machine oil in the different oil baths can circulate each other for oil pan oil drain is smooth and easy and be favorable to reducing oil pan bottom machine oil and remain when the maintenance.

In order to ensure the strength and the mode of the oil pan, a plurality of reinforcing rib plates 11 are arranged at the bottom of the inner cavity of the oil pan body 10 at intervals, the plate surfaces of the reinforcing rib plates 11 are arranged in the vertical direction, and the through holes 111 formed in the reinforcing rib plates 11 are beneficial to discharging engine oil and have the function of reducing the weight of the oil pan to a certain extent.

As a preferable scheme of the present invention, the through hole 111 and the oil drain hole 12 on each reinforcing rib plate 11 are located in the same vertical plane, that is, the hole cores of the through hole 111 and the oil drain hole 12 are located on the same straight line (a straight line in a non-horizontal plane), which is beneficial to the flow of the engine oil and reduces the oil drain time.

According to the characteristic that liquid flows from a high position to a low position, the bottom wall of the oil pan body 10 is arranged obliquely, and the oil drain hole 12 is arranged at the junction position of the side wall and the bottom of the oil pan body 10 at the bottommost position. Therefore, the oil in the oil pan flows from the high level to the oil drain hole 12 at the bottom and is drained, and the oil residue at the bottom of the oil pan is further reduced.

The oil drain hole 12 is obliquely arranged in accordance with the bottom wall of the oil pan body 10, so that the oil drain hole is more favorable for discharging the engine oil.

The outer wall of the oil pan body 10 is integrated with a mounting boss 13, and a part of engine accessory mounting points are integrated, so that the rigidity and NVH performance of the engine are improved. At the same time, the compactness of the engine arrangement is also increased.
