Technical Field
The utility model relates to the technical field of diesel engine manufacturing, in particular to a special-shaped large-inclination-angle oil bottom box.
Background
Along with the continuous development of modern technology, the functions are increased, the installation space of the diesel engine is more and more compact, and meanwhile, the required climbing angle (comprising pitching and rolling) of the whole vehicle is continuously increased. These requirements are met by employing a dry sump in combination with an external sump; and secondly, the oil pan with the oil pool with larger volume is adopted. The oil pan generally adopts cast aluminum structure, and now because the space is limited, the shape is complicated, satisfies whole car inclination demand.
The oil pan lubricating structure needs to be integrally planned, so that the oil pan can meet the use requirements of space installation and large inclination angle.
The prior art can not meet the requirements of the whole vehicle on working inclination angle and space installation under the condition of meeting the lubricating index requirements of the diesel engine.
Disclosure of utility model
In order to solve the defects, the utility model provides the special-shaped large-inclination-angle oil bottom box, which adopts a special-shaped casting structure to simultaneously meet the requirements of lubricating a diesel engine, space installation, working inclination angle of the whole vehicle and the like, so that the diesel engine is more compact in structure, can be used in a narrow space, and reserves a larger arrangement space for the whole vehicle.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
The utility model provides an oil bottom case at big inclination of abnormal shape, includes returns oil pump, hydraulic oil pump and oil pan, the oil pan comprises big, little oil pool, and big oil pool keeps apart with little oil pool through the oil baffle, the import and the little oil pool intercommunication of oil return pump, the export and the big oil pool intercommunication of oil return pump, the import and the big oil pool intercommunication of hydraulic oil pump.
The utility model further improves that the mounting surface of the oil pan is a flange surface.
A further development of the utility model consists in that the scavenging pump, the pressure oil pump are arranged above the small oil sump.
The utility model further improves that the oil return pipe of the oil return pump is connected with the oil baffle plate through the first fixing bracket.
The utility model further improves that the oil suction pipe of the oil pressing pump is connected with the oil baffle plate through a second fixed bracket.
The utility model further improves that the large oil tank is provided with an oil dipstick mounting seat.
By adopting the technical scheme, the utility model has the following technical progress:
1. the structure is reasonable and compact, and the lubrication requirement of the working condition of the large inclination angle of the diesel engine can be met.
2. The whole height is smaller, and the whole car arrangement requirement is met.
Drawings
FIG. 1 is a schematic view of the overall structure of the present application;
fig. 2 is a schematic view of the structure of the oil pan of the present application.
The oil return device comprises a flange surface 1, an oil baffle plate 2, a small oil tank 3, an oil baffle plate 4, a large oil tank 5, an oil dipstick mounting seat 6, an oil return pipe of an oil return pump 7, an oil suction pipe of the oil return pump 8, the oil return pump 9, an oil pump 10 and an oil suction pipe of an oil pump.
Detailed Description
The utility model is further illustrated by the following examples:
The utility model provides a special-shaped large-inclination oil bottom box, which is shown in figures 1-2 and comprises an oil return pump 8, an oil pump 9 and an oil bottom shell.
The oil pan is composed of a large oil tank and a small oil tank, the large oil tank 4 is isolated from the small oil tank 2 through an oil baffle 3, the large oil tank 4 can design the volume of the large oil tank 4 according to design requirements, an oil suction pipe 7 of an oil return pump is communicated with the small oil tank 2, an oil return pipe 6 of the oil return pump is communicated with the large oil tank 4, and an oil suction pipe 10 of a pressure oil pump is communicated with the large oil tank 4.
Optionally, the mounting surface of the oil pan is a flange surface 1, and the flange surface 1 is provided with a mounting hole for connecting with an engine body.
Optionally, in order to utilize the limited space, a scavenging pump 8, a pressure oil pump 9 are arranged above the small oil sump 2.
Alternatively, since the scavenging pump 8 is located above the small oil pool 2, the scavenging pipe 6 of the scavenging pump may be lengthened, and may be fixed with the oil baffle 3 by a fixing bracket so as not to vibrate the scavenging pipe.
Alternatively, at the same time, the oil pump 8 is fixed with the oil baffle 3 by a fixing bracket, and the oil pump 9 is arranged as the oil return pump 8.
Optionally, in order to observe how much oil is, a dipstick mount 5 is mounted on the large oil sump 4.
The working process and the application are as follows:
1. The oil pan is a wet oil pan and has the main function of providing enough lubricating oil for normal operation of the diesel engine. However, the oil pan is different from an oil pan with a common structure and a deeper oil pool, and the oil pool can be arranged in the transverse direction only due to the limitation of the space of the whole machine, so that the lubricating oil quantity requirement of a diesel engine is met by adopting a special structure.
2. It can be seen from fig. 2 that the oil pan is connected with the crankcase of the diesel engine through the flange face 1 bolts, and two large and small oil tanks are arranged together, the oil pump 9 and the oil return pump 8 are respectively arranged, the oil pump 9 absorbs oil from the large oil tank 4 to lubricate the whole engine, gravity flows back into the small oil tank 2 after passing through each friction pair, the oil return pump 8 sucks oil into the pump through the oil suction pipe, and then the oil return pipe sends the lubricating oil into the large oil tank 4, so that the oil pump 9 can suck enough lubricating oil to lubricate the whole engine, and the diesel engine can normally work under various working conditions and large inclination angles (pitching 32 degrees and rolling 20 degrees).
3. The oil pan has compact structure, the whole body can be arranged at about 180mm, the space is saved, and the severe requirement of the whole car arrangement is met.
The above examples are only illustrative of the preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model, and various modifications and improvements made by those skilled in the art to the technical solution of the present utility model should fall within the scope of protection defined by the claims of the present utility model without departing from the spirit of the design of the present utility model.
