Abstract
The forced lubricating pump for engine consists of forced lubricating pump and DC motor, and may be used in various motor vehicle and ships. Oil inlet pipe and oil outlet pipe are connected to crankcase oil tray and main oil duct separately. The forced lubricating pump is driven by the DC motor with control system. During the operation, the DC motor is first started to drive the forced lubrication pump before the engine is started, the engine oil inside the crankcase oil tray is pumped out and conveyed to the main oil dust and the surface of various driving parts and the surface of the parts has one layer of oil film before the engine is started. Thus, the "dry friction" can be eliminated radically.
Description
Technical field
What the present invention relates to is a kind of design and the manufacturing technology field that can eliminate the lubricant pump of motor " dry friction " phenomenon.
Background technique
The modern automotive car engine is to be the energy with gasoline, diesel oil, is with formations such as crankshaft-link rod, distribution devices on the structure.Behind the engine start, its running force-transmitting member is to guarantee its proper functioning under high speed, high temperature, condition of high voltage by lubricating oil.There is not the oil lubricating motor just can not work.And the lubricating system of modern motor is composite lubricated by the combination of pressure lubrication and splash lubrication dual mode, guarantees the lubricated of engine running force-transmitting member.Depended on pressure lubricated critical piece is as crankshaft bearing, connecting rod bearing, camshaft bearing casing wall and piston etc.The lubricated of these parts is behind engine start, and machine oil pumps the machine oil that certain pressure is arranged under the effect of oil pump in engine sump tank, deliver to each force-transmitting member through fuel filter, primary oil filter etc.Make these parts surfaces form one deck oil film, make parts surface become indirect friction, to guarantee the motor proper functioning by direct friction.But motor stagnation of movement a period of time before relaunch, especially before the cold start engine, the machine oil of each parts surface all is back in the engine sump tank more than 90% under the effect of gravity in the motor.Just there is not machine oil between the part of engine running power transmission at this moment.And motor from start oil pump work to oil delivery to each running force-transmitting member surface, then need 15～40 seconds time.And high engine speeds running during this period of time just is in the direct friction state between each parts.Its wear extent is quite big.Nei direct friction is exactly " dry friction " that is commonly called as during this period of time.Show that according to test once the wear extent of " dry friction " is equivalent to the wear extent of 1200 kilometers of automobile runnings, very big to the influence in working life of motor.Being consumed by " dry friction " more than 50 percent of motor car engine life-span.For solving " dry friction " phenomenon, be present a great problem.Up to the present, also do not have not sell on market with like products of the present invention or use in practice.
Summary of the invention
The purpose of this invention is to provide a kind of lubricant pump that can solve " dry friction " problem effectively, to increase substantially the working life of motor.Structure of the present invention is as shown in drawings: be made of pressure lubrication pump and motor.Have direct current motor on the pressure lubrication pump, motor has motor control system, and magnetic switch and start button etc. are arranged on the control system.Have filler opening and oil outlet on the lubricant pump.Filler opening and oil outlet have oil inlet pipe and oil outlet tube respectively, and oil inlet pipe is connected on the engine sump tank, and oil outlet tube is connected on the motor main oil gallery.On the lubricated pump shaft connecting sleeve is arranged.By connecting sleeve and the direct current drive arbor knot that links.Have land on the lubricated pump housing, be fixed together by tie-plate and direct current motor shell.Installation method of the present invention is: the pressure lubrication pump is installed in motor main oil gallery one side, is fixed on the automobile frame, oil inlet pipe is connected on the oil sump, oil outlet tube is connected on the motor main oil gallery.Start button etc. is installed in the operator cabin.With the accumulator of motor-driven vehicle is power source.Using method of the present invention is: before engine start, press start button earlier, start direct current motor, the motor drives lubricant pump, machine oil in the oil sump is transported to the motor main oil gallery by oil inlet pipe, oil outlet tube, be transported to the surface of the force-transmitting member that respectively turns round respectively by main oil gallery, make it before engine start, just form oil film at each parts surface.And then ato unit, original " dry friction " phenomenon is fundamentally disappeared, can increase substantially the working life of motor, the present invention is simple in structure, and is reasonable in design.Can fundamentally solve motor " dry friction " problem, prolong the working life of motor significantly.Using effect is very good.
