Description
Technical field
The present invention relates to the component of motor, refer to particularly a kind of housing structure of motor car engine.
Background technique
The cylinder bottom generally is provided with oil sump, and oil sump is the Lower Half of crankcase, is called again lower crankcase, and its effect is to seal crankcase as the shell of oil storage tank, prevents that impurity from entering, and collects and store the lubricant oil that is flowed back to by each friction surface of motor.Traditional motor in the running, each rubbing surface is back to the machine oil of oil sump from motor, has greatly can continue to move along with the motion of crankshaft rod system, can cause like this frictional work of motor to increase; Machine oil in the oil sump can be splashed on the crankshaft rod system in addition, hinders the motion of crankshaft rod system, thereby has further increased the frictional work of motor.Therefore design a kind of rational engine cylinder body structure, get back to fast oil sump in order to make backflow machine oil, stop that the machine oil in the oil sump can be splashed on the crankshaft rod system, the oil level that minimizing continues to move with the motion of crankshaft rod system, thereby reduce the frictional work of motor, become problem demanding prompt solution.
Summary of the invention
The purpose of this invention is to provide a kind of novel engine cylinder body structure, so that the machine oil that refluxes from each friction surface of motor can Rapid Flow oil return drain pan, the oil level that minimizing continues to move with the motion of crankshaft rod system, simultaneously, prevent that the machine oil in the oil sump from spattering to crankshaft rod system, and will guide in the oil sump fast in company with the machine oil that crankshaft rod system moves together, thereby reach the purpose that reduces the engine running frictional work.
For achieving the above object, the technical solution used in the present invention is: a kind of housing structure of motor car engine, the oil sump that it comprises cylinder body and is located at cylinder base is provided with the first deflector structure at cylinder body bottom one sidewall, be provided with the second deflector structure at another relative sidewall, the position of the second deflector structure vertical direction is higher than the first deflector structure, and the first deflector structure is provided with guide channel.
The present invention passes through in cylinder base, the below that is crankshaft rod system arranges the first deflector structure, so that the machine oil that refluxes from motor is guided through guide channel Rapid Flow oil return drain pan by the first deflector structure, the oil level that minimizing is moved along with the motion of crankshaft rod system is avoided stagnating and is hindered the motion of crankshaft rod system with machine oil; Simultaneously, the first deflector structure is positioned at the crankshaft rod system below and which is provided with guide channel, bottom of the present invention is separated into the cavity of two relatively independent and don't complete closed, motion in the superincumbent cavity of crankshaft rod system, the machine oil that flows back to oil sump is intercepted in the oil sump, thereby avoid the machine oil in the oil sump to be splashed on the crankshaft rod system, significantly reduced the oil level in the crankcase, reduced the obstruction of machine oil to the crankshaft rod system motion; In addition, the second deflector structure is set above the guide channel on the first deflector structure, the second deflector structure will be led back to the first deflector structure fast in company with the machine oil that crankshaft rod system moves upward together, finally flow in the oil sump from guide channel, reduce the oil level in the crankcase, thereby further reduced the frictional work in the engine operation process; The present invention is simple and compact for structure, has effectively reduced the frictional work of motor, has reduced kinetic equation loss, has improved the efficient of motor, has saved operating cost.
Further, described the second deflector structure comprises guide plate, and the guide plate top is provided with fixed plate, and the guide plate both sides are respectively equipped with stiffening plate.Guide plate mainly plays guide functions; Stiffening plate is used for improving the integrally-built rigidity of the second guide plate and intensity; Fixed plate is the face that fixedly provides support of the second deflector structure, and the second deflector structure is installed on the cylinder side wall by fixed plate.
Again further, described guide plate is a bent plate that tilts, and the middle part of bent plate is provided with opening.The bent plate that tilts is conducive to from top to bottom water conservancy diversion; The opening at bent plate middle part is used for making allowances to crankshaft rod system, and the joint space-efficient has been avoided interfering with each other between crankshaft rod system and bent plate simultaneously.
Further, described bent plate comprises the arc plate of upper end, and from the terminal swash plate toward having a down dip and extending of arc plate.The swash plate that tilts to extend is used for water conservancy diversion, and the arc plate that joins with swash plate provides supporting surface for fixed plate, has also avoided occurring knuckle simultaneously, is conducive to the space layout of cylinder interior.
Preferably, described stiffening plate is perpendicular to guide plate, and the upper edge of stiffening plate is fixing along fitting with the side of guide plate.The stiffening plate that arranges perpendicular to guide plate when improving the second deflector structure rigidity and intensity, it on along with the side of guide plate along fully applying, be conducive to reduce guide plate because of the improper vibrations that crankshaft rod system moves and produces, abate the noise.
Further preferably, described the first deflector structure comprises that head end is fixed on the horizontal expansion plate on the cylinder side wall, and the end of horizontal expansion plate is bending downwards near another side-walls of cylinder body.The large size horizontal expansion part of the first deflector structure can separate crankshaft rod system and oil sump effectively; Its end when the horizontal expansion plate extends near cylinder side wall, that is: extending end, gradually bending downwards, this bending part can guide to the machine oil that refluxes from the top motor the oil sump of below well, leave one section little gap between the cylinder side wall of the bending part of horizontal expansion plate and vicinity, form the guide channel that machine oil flows into oil sump; A machine oil part that refluxes from motor at first flows into the housing oil sump behind the first deflector structure water conservancy diversion.
