Abstract
The utility model discloses a main bearing cap with a screw hole on the lateral and an air cylinder cooperating with the main bearing cap and a lateral fixing hole is positioned on the air cylinder at a position cooperating to said screw hole of the main bearing cap. The air cylinder and the main bearing cap are connected to form a whole by bolts and the whole is pressed evenly to avoid the situation that an instant pressure is too big to cause the air cylinder deformed, thus, a series of problems cased by the deforming of the air cylinder is avoided; the rigidity and strength of the air cylinder are improved and the weight of the air cylinder is reduced. As a result, a good effect of heat distributing is achieved.
Description
Technical field
The utility model relates to engine art, particularly a kind of main bearing cap and a kind of cylinder block that is used for motor.
Background technique
Motor is the machine that chemical energy is converted into mechanical energy, in fact its conversion process is exactly the process of work cycle, be exactly to be fuel in simple terms by in the combustion cylinders, produce kinetic energy, drive the reciprocal motion of piston in the cylinder, drive the connecting rod and the crank that links to each other with connecting rod that is connected on the piston thus, make reciprocal circular movement around crankshaft center, and outputting power.
Engine cylinder is important in a motor mechanical parts, and cylinder block is the skeleton that constitutes motor, is the installation basis of each mechanism of motor and each system, its inside and outside all major parts and annex that motor is installed.
Cylinder block is born very complicated load when engine running, each gas in the jar is to the even atmospheric pressure of cylinder head bottom surface and cylinder surface, through the lateral force of piston action in each casing wall, be added in power on each main bearing through bent axle, support is to each countertorque of supporting force of motor.The size of these power, direction constantly change with operating mode and crank angle, and the point of action of some power is also in continuous variation.In addition, even when motor does not turn round, each cylinder head bolt, Main bearing bolt also make fastened part stressed.More than various power and moment make the cylinder block each several part be subjected to the tension and compression bending of alternation, produce complicated stress phase.
Therefore, cylinder block must have enough strength and stiffness, crackle and damage can not take place, excessive distortion can not appear, especially the junction of cylinder block and cylinder head, cylinder liner, main bearing seat etc. are located, if insufficient rigidity will produce serious consequences such as seal failure, friction pair wearing and tearing aggravation, cylinder block extensional vibration aggravation, cylinder block generation additional stress
In all kinds of motors of on market, using at present, its engine cylinder generally all be alloy cast iron because the price of cast iron is low, the tensile strength height is used more extensive.The density of cast iron is big, and thermal conductivity is little, so cast-iron cylinder block has weight big, the shortcoming of radiating effect difference.
In order to solve the shortcoming of cast-iron cylinder block, also there is minority engine cylinder material to adopt the density of aluminum alloy aluminum alloy little, thermal conductivity is big, density has only 1/3rd of cast iron, thermal conductivity is four times of cast iron, so Aluminum Alloy Cylinder Barrel has well solved the heavy and bad problem of radiating effect of former cast-iron cylinder block.
In expansion space stroke, piston bears gaseous-pressure moving linearly in cylinder, converts rotatablely moving of bent axle to by connecting rod, and from the external outputting power of bent axle.And in air inlet, compression and exhaust stroke, flywheel releases energy and rotatablely moving of bent axle is changed into the straight line motion of piston.And the suffered power of bent axle is all born by the main bearing seat on the cylinder block.
Existing a kind of Aluminum Alloy Cylinder Barrel in upright arrangement, the cross-section structure of its main bearing seat position as shown in Figure 1, main bearing cap 40 only links to each other with main bearing seat (also being cylinder block 10) by Main bearing bolt 20,30.
In motor, each cylinder is not to do work simultaneously, thereby the stressed of each main bearing seat be alternate, and the tensile strength of aluminum alloy is low, so cause the cylinder block distortion very big.In case and following problem can appear in the cylinder block distortion:
A. scurry under the high-temperature gas, the oil temperature height causes machine oil rotten;
B. cylinder seal is bad, and cylinder pressure descends, and causes engine power to descend;
C. because cylinder leakage tester causes engine consumption to increase;
D. cylinder gap is excessive, and oil film forms bad, and the frictional force between friction pair increases greatly, causes the early stage abrasion of motor movement parts;
E. cylinder head plane deformation: bad with the cylinder head sealing, so that motor gas leakage, occurring cylinder pressure simultaneously and descend, power descends, the problem that oil consumption increases;
F. be out of shape and cause piston-cylinder to overlap this friction pair malfunction when serious, thereby scuffing of cylinder bore or stuck phenomenon occur, cause whole motor to damage.
Summary of the invention
The purpose of this utility model is the defective that overcomes above-mentioned prior art, and a kind of novel main bearing cap and cylinder block are provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of main bearing cap, its side are provided with at least one side screw.Left and right sides face all can be provided with at least one described side screw.
In addition, described main bearing cap is provided in a side of the main bearing cap of motor intermediate main bearing seat.
The technical solution of the utility model also comprises a kind of cylinder block, and position corresponding with above-mentioned side screw on it is provided with the side of cylinder block fixed hole.Its left and right sides all can be provided with described side of cylinder block fixed hole.This side of cylinder block fixed hole is a screw.
In addition, described cylinder block is V-type six cylinder cylinder block.
Positive progressive effect of the present utility model is: cylinder block and main bearing cap can be connected in one by bolt, make whole stressed even, stressed excessive situation when well having avoided instantaneous innings, thereby the stressed excessive cylinder block distortion that produces when having reduced greatly because of instantaneous office, so also fundamentally prevented to be out of shape a series of problems that occur because of cylinder block, improve the rigidity and the intensity of cylinder block, and alleviated the weight of cylinder block, also had good heat-radiation effect.
