Abstract
The utility model discloses a lubrication system of motor car engine. Surface of a cranked main journal bearing hole (4) of a main bearing seat (1) on a cylinder body is provided with oil holes communicating with a main oil line. A communicating boosted oil hole is arranged between the surface and outer side face of the cranked main journal bearing hole (4) of the main bearing seat (1). By comparing the technical proposal above with exiting lubrication system of motor car engine, the utility model increases the pressure of lubrication on the cylinder, and improves stability of lubrication, which make a cylinder wall, a piston, a piston ring and a piston pin get enough lubrication, thus improving performance of the engine, and prolonging service life of the engine.
Description
Technical field
The utility model relates to automobile chassis, and more particularly, the utility model relates to a kind of automotive engine lubrication system.
Background technique
At present, in motor car engine, for the bigger friction surface of load, as crankshaft journal and connecting rod bearing, cam journal and the camshaft bearing etc. of crankshaft main journal and main bearing, bent axle, all adopt the mode of pressure lubrication, promptly lubricant oil is infeeded friction surface and be lubricated with certain pressure.This mode is lubricated reliable, but structure is comparatively complicated.For the lighter distribution device of picture load, as cam, tappet, valve stem and rocking arm etc., then adopt the mode of splash lubrication or spray lubrication, the moving part bump machine oil that changes splashes the next oil droplet or the mode of oil mist lubrication friction surface when promptly utilizing engine operation, or is injected into reciprocating friction surface through oilhole.This mode is simple in structure, but reliability is relatively poor.
The speed of related movement of cylinder or cylinder liner and piston is big in motor car engine, working surface temperature height, and abrasion is serious, needs well lubricated and cool condition.But be subjected to the restriction of structure, in present various types of motor car engines, can only adopt splash lubrication.Lubricant oil branch multichannel behind main oil gallery enters each main bearing lubrication, and then, the inclined oil hole of air on bent axle flows to crankpin bearing lubrication, sprays to cylinder wall from the connnecting rod big end oilhole again, and lubricated cylinder, piston, piston ring and wrist pin flow back to oil sump afterwards.Lubricant oil is to carry out the lubricated connecting rod that flows to again later of main bearing, and oil pressure descends; Connnecting rod big end is moving, and oilhole sprays can't guarantee to be injected into the desired position, and therefore, lubricated effect is not ideal enough, has influenced the proper functioning of motor, has reduced service life.
The model utility content
Problem to be solved in the utility model provides a kind of automotive engine lubrication system, its objective is to strengthen the lubricated of cylinder wall and piston etc.
To achieve these goals, the technological scheme that the utility model is taked is: this automotive engine lubrication system that is provided, the surface of the crankshaft main journal bearing hole of the main bearing seat on its cylinder body is provided with the oilhole that communicates with working connection, described main bearing seat is established a supercharging oilhole that communicates between the surface and outer side surface of its crankshaft main journal bearing hole.
Described supercharging oilhole is a step hole, its in the aperture of crankshaft main journal bearing hole one side of main bearing seat greater than its aperture in outer side surface one side of main bearing seat.
The radial skew of the crankshaft main journal bearing hole of the axis of described supercharging oilhole and main bearing seat, shape in an angle.
Described supercharging oilhole leans on the outer side surface aperture of main bearing seat to establish the oilhole outer end counterbore of a coaxial line, and the bottom surface of oilhole outer end counterbore is perpendicular to the axis of supercharging oilhole.
In described supercharging oilhole, establish the oil pipe spigot that cooperates with two step internal diameter, its underside portion that stretches out oilhole outer end counterbore connects with the oil pipe socket by screw thread, if the termination of oil pipe is in the hole of oil pipe socket, the diameter of the termination of oil pipe is greater than the aperture on the interior edge face of oil pipe socket.
Technique scheme is compared with the lubrication system on the present motor car engine, the utility model has improved the pressure of lubricant oil at the cylinder place, improved lubricated stability, it is lubricated more fully that cylinder wall, piston, piston ring and wrist pin are obtained, improve the performance of motor, prolonged its working life.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the supercharging oilhole shown in Figure 1 and the structural representation of oil pipe connection.
Number in the figure is: 1, main bearing seat, 2, oilhole outer end counterbore, 3, the supercharging oilhole, 4, the crankshaft main journal bearing hole, 5, main journal hole oil groove, 6, the oil pipe spigot, 7, the oil pipe socket, 8, oil pipe.
Embodiment
Shown in the structural representation that supercharging oilhole and the oil pipe of the structural representation of the present utility model of Fig. 1, Fig. 2 connects, the utility model is an a kind of automotive engine lubrication system, the surface of the crankshaft main journal bearing hole 4 of the main bearing seat 1 on its cylinder body is provided with the oilhole that communicates with working connection, lubricant oil branch multichannel behind main oil gallery enters each main bearing lubrication, and the main journal and the main bearing rubbing surface of bent axle is lubricated.Also be provided with main journal hole oil groove 5 on the surface of the crankshaft main journal bearing hole 4 of main bearing seat 1, make the main journal all surfaces of bent axle fully to contact, improve lubricating efficiency with lubricant oil.
Technical conceive of the present utility model is to get lubricant oil on main bearing seat 1, lubricant oil is directly introduced being lubricated to cylinder wall and piston.Its concrete measure is: described main bearing seat 1 is established a supercharging oilhole 3 that communicates between the surface and outer side surface of its crankshaft main journal bearing hole 4.This is a passage of getting lubricant oil from main bearing seat 1.By pipeline lubricant oil is delivered to cylinder wall then, improve the oil pressure of this place's lubricant oil.
The radial skew of the crankshaft main journal bearing hole 4 of the axis of supercharging oilhole 3 and main bearing seat 1, shape in an angle.The purpose of this structure is convenient at place, aperture processing counterbore, so that the fixedly oil pipe socket 7 of usefulness of oil pipe 8 is installed.
In supercharging oilhole 3, establish the oil pipe spigot 6 that cooperates with two step internal diameter, its underside portion that stretches out oilhole outer end counterbore 2 connects with oil pipe socket 7 by screw thread, if the termination of oil pipe 8 is in the hole of oil pipe socket 7, the diameter of the termination of oil pipe 8 is greater than the aperture on the interior edge face of oil pipe socket 7.The other end of oil pipe 8 directly leads to the cylinder wall place, cylinder wall, piston, piston ring and wrist pin is carried out lubricated fully with the profit oil with elevated pressures.
Technique scheme is compared with the lubrication system on the present motor car engine, the utility model has improved the pressure of lubricant oil at the cylinder place, improved lubricated stability, it is lubricated more fully that cylinder wall, piston, piston ring and wrist pin are obtained, improve the performance of motor, prolonged its working life.
