Abstract
The utility model discloses a bolt-transfixion structure used engine, which comprises a cylinder head (1), a cylinder head gasket (2), a positioning rhombic pin (3), a cylinder block (4), a positioning pin ( 5), a crankcase (6), a transfixion bolt(7), a positioning rhombic pin (8), a positioning pin ( 9), as well as other engine internal structure parts and external annexes. The utility model is characterized in that the transfixion bolt (7) runs through the crankcase (6), the cylinder block (4), the cylinder head gasket (2), and is fixed on the cylinder head (1). The advantages of adopting such bolt are that the engine only accepts tensile stress, the deformation of the cylinder liner is small, the reliability of piston pair parts use is high, the technology is simple, the cylinder block leaves out the complicated strengthening ribs, the manufacturing cost is low, the combustion performance is good, the noise is small. This transfixion bolts are suitable for diesel, petrol engine use, especially in the use of all-aluminum engine structure.
Description
Technical field
The utility model relates to a kind of motor with through bolt structure.
Background technique
High Temperature High Pressure in the engine behavior cylinder, high speed relative movement between piston pair and the cylinder sleeve, the distortion of cylinder sleeve directly have influence on the complete machine Performance And Reliability of motor.Usually, engine cylinder and cylinder head, the fastening of cylinder block and crankcase is relatively independent, passing cylinder head with bolt between cylinder block and the cylinder head is fastened on the cylinder block, same cylinder block also is to use bolton separately with being connected of crankcase, the cylinder block of this structure is especially born very high tensile stress when cylinder sleeve and near the burning of dividing plate thereof, cause the distortion of cylinder sleeve big, have influence on the lubrication effect and the endurance quality of piston pair, thereby have influence on the complete machine Performance And Reliability of motor, especially remarkable for the conventional cast Aluminum Alloy Cylinder Barrel influence that the tensile fatigue ultimate strength is low.
Summary of the invention
The purpose of this utility model be to provide a kind of overcome the available engine cylinder block especially cylinder liner be subjected to high tensile stress and deformed configurations, promptly adopt through bolt that cylinder block, crankcase, cylinder head are tightened together, realize improving the motor with through bolt structure of motor complete machine Performance And Reliability.The technological scheme that the utility model solves is, comprises cylinder head gasket, cylinder block, crankcase, through bolt, and feature is that through bolt passes crankcase, cylinder block, cylinder head gasket and is fastened on the cylinder head.
Cylinder block has the through hole that through bolt is installed, and crankcase has the through hole that through bolt is installed, and cylinder is stamped the screw that through bolt is installed.
The utility model has the advantages that: all dividing plates of cylinder block and cylinder sleeve almost only are subjected to tensile stress, and the cylinder sleeve of engine distortion is little, the secondary part operational safety of piston motion height; Cooperate combustion chamber scheme and the oil supply system scheme optimized, the engine combustion performance is good, and combustion noise is little; When adopting aluminium cylinder block, not resembling conventional motor needs cast iron edge circle to go supports main shaft to carry lotus, and cylinder block does not need complicated stiffening rib yet, has simplified manufacturing process; When adopting Aluminum Alloy Cylinder Barrel, the operational safety requirement can be satisfied, manufacture cost can be reduced effectively with conventional material and heat treatment process; Be suitable for diesel oil, petrol engine use.
