Description

The utility model relates to the field of transport engineering and is used as a noise-damping sump of the crankcase of an internal combustion engine, which protects the crank mechanism from dust and dirt, and also serves as a collection of lubricating oil.

Known engine oil pan according to patent RU 2115007. The pallet is mounted on the engine block of the engine and is made in the form of a sheet part, including the bottom and connecting parts. An oil damper is located at the bottom.

The disadvantages of the known pallet are:

- increased weight due to its manufacture from metal;

- the need to use a casing that protects the pallet from shock, as it is made of a thin-walled sheet;

- insufficient noise absorbing properties of a thin-walled metal sheet;

- a relatively high manufacturing cost.

Known engine oil pan according to patent RU 2115813. The pallet is mounted on the ICE crankcase and contains interconnected bottom and top parts. The bottom part is made of a single layer of thin sheet metal, and the upper part is made of a three-layer metal-plastic-metal material. Direct hard contact between the parts may be absent due to the installation of a vibration damping element in the connecting joint. Mutual fastening of parts of the pallet can be both detachable and one-piece.

The disadvantages of the known pallet are:

- design complexity;

- increased weight due to the use of metal elements in the design;

- insufficient resistance to shock loads;

- insufficiently high noise vibration damping properties;

- the complexity of the manufacturing process;

- relatively high cost;

- the unresolved issue of the choice of seal material between the upper part of the pallet and the crankcase.

A well-known pan of the crankcase of an internal combustion engine, the body of which is made of a polymer composite material, namely, fiberglass reinforced polyamide Zytel 70G35 HSLRA4, developed by EIringKlinger (see information on September 29, 2009, posted on the Internet at: http: // www .plastic.ru / index.php? lang = ru & view = news & category_id = 28 & entry_id = 7681), selected as a prototype.

In the manufacture of the prototype pallet, an additional reinforcing component is required and the reinforcement operation is added, which increases the cost of the product (pallet) and complicates the process, since the cost of raw materials and electricity increases, as confirmed by the source Plastinfo.ru (see information on the Internet by email. address: http // mpol.ru / howto / novosti-rynka-upakovki / dupont-polishaet-ceny-n ...). These shortcomings of the prototype pallet, the casing of which is made of Zytel glass fiber reinforced polyamide 70G35 HSLRA4, are eliminated in the claimed technical solution, the task of which is to reduce the cost of the product.

The technical result is:

- simplification of the product and the manufacturing process due to the exclusion of fiberglass reinforcement of polyamide;

- reducing the cost of the pallet due to the exclusion of reinforcing fiberglass and reducing the share of energy costs (for reinforcement).

The technical result is achieved by the fact that in the sump of an internal combustion engine containing a housing made of a polymer composite material, a sealant, fasteners, according to the first embodiment of the utility model, the housing is made of REVA polyester blockamide, the sealant is made of rubber compound.

The technical result is achieved by the fact that in the oil pan of the internal combustion engine, comprising a housing made of a polymer composite material, a sealant, fasteners, according to a second embodiment of the utility model, the housing is made of polymer of the brand Arkaim, the sealant is made of rubber compound.

The technical result is achieved by the fact that in the oil pan of the internal combustion engine, comprising a housing made of a polymer composite material, a sealant, fasteners, according to the third embodiment of the utility model, the housing is made of PBT polymer, the sealant is made of rubber compound.

The technical result is achieved by the fact that in the sump of an internal combustion engine containing a housing made of a polymer composite material, a sealant, fasteners, according to a fourth embodiment of the utility model, the housing is made of POM-polymethylene polymer, the sealant is made of rubber compound.

The properties of the Arkaim polymer are described in TU2224-004-99232081-2009 (see information published on the Internet at: http://www.chelcsm.ru/products/all/222490/5397/ and at the email address: http: //www.google.com/search?ie=UTF-8&hl=en&q=%D0%BF%D0%BE%DO%...). Specifications TU2224-004-99232081-2009 for Arkaim polyetherblockamide were registered on March 30, 2009 at the Chelyabinsk Center for Standardization, Metrology and Certification (number 074/011999).

The implementation of the crankcase of the above polymer grades allowed to reduce the cost of the pallet, as these materials are cheap, as well as to simplify the product and the manufacturing process due to the exclusion of glass fiber reinforced polyamide.

In addition, the execution of the housing of the crankcase of the above polymer grades, as shown by experimental tests, increased tensile strength compared to the prototype pallet, the body of which is made of fiberglass-reinforced polymer brand Zytel polyamide 70G35 HSLRA4.

All of the listed grades of polymer composite materials of which the pallet body is made have the ability to work in the temperature range from -50 to +125 degrees Celsius, and are resistant to the effects of lubricating oils and fuels. They have sufficient viscosity, as a result of which they are well resistant to shock loads. Their specific gravity, lower than that of metals, allows the housing wall to be made with a greater thickness, which provides a significant increase in the noise and vibration damping properties of the pallet. The fact that the body of the pallet is made integral, simplifies its design, and this, in turn, allows us to simplify the technology of its manufacture.

The applicant, together with KAMAZ LLC, conducted sea trials of oil sumps on the engines of association vehicles in various climatic conditions. The tests revealed high reliability and durability of pallets, good tightness of the connection of pallets with engine crankcases, and an increase in noise and vibration damping properties compared to metal pallets.

The essence of the proposed utility model is illustrated by drawings.

Fig. 4 shows a section A-A in Fig. 1.

The pallet of the crankcase of the internal combustion engine contains a housing 1 made of a polymer composite material, inside of which partitions are made 2. On the end connecting surface 3 of the housing 1, a groove 4 is made, in which a seal 5 made of rubber compound is installed. In the connecting collar 6 of the housing 1, through holes 7 are made, in which the screws 8 for securing the pan to the engine crankcase are placed. Between the bottom end of the shoulder 6 and the heads of the screws 8, springs 9 are installed to compensate for temperature stresses.
