Abstract

A composite driving device for a machine oil pump of an engine is formed by a driving shaft, a machine oil pump impeller, a mechanical driving mechanism and a motor driving mechanism, wherein one end of the driving shaft is fixedly connected with the machine oil pump impeller, the mechanical driving mechanism is composed of a belt pulley and a ratchet wheel pawl device, two sets of pawls are symmetrically arranged on the inner side of the belt wheel, the pawls are matched with the ratchet wheels, and the ratchets are fixed at one end of the driving shaft. The ratchet wheel pawl device at the position belt pulley guarantees complete separation of the driving shaft and the mechanical driving mechanism when the motor works, thereby avoiding consumption of excess energy. The machine oil pump is driven by the motor driving mechanism to work, thereby resolving the problem of machine oil carbonization caused by partial high temperature when the engine suddenly shuts down, and avoiding damage of parts of the engine. By means of an intelligent control system, the engine is enabled to be in good lubrication and radiation states always, thereby prolonging service life of the engine.

Description

A kind of engine oil pump combined driving device
Technical field
The utility model relates to a kind of engine motor oil pump drive, is particularly useful for the compound drive pattern of bent axle, motor of turbosupercharged engine oil pump, belongs to technical field of internal combustion engines.
Background technique
Motor is as the power resources of automobile; The quality of its workmanship directly has influence on the usability of car load; And engine oil pump can in time provide machine oil, is the necessary condition that guarantees that machine runs well, because motor not only need lubricate heat radiation when proper functioning; And also require to continue heat radiation after shutting down, with the engine failure that prevents that local long-time high temperature from causing damage of components and machine oil carbonization to cause.At present; Automobile engine oil pump generally adopts the crank-driven mode, and after the high engine speeds running was shut down suddenly, oil pump also quit work; Can't be dispelled the heat rapidly in gas distribution system and cylinder body part and cause engine failure, especially even more serious to the negative effect that turbosupercharged engine brought.
The model utility content
The purpose of the utility model is the disadvantage that exists to present automobile engine oil pump driving mode, a kind of intelligent control is provided, can be motor engine oil pump combined driving device lubricated and heat radiation machine oil in time is provided.
The said problem of the utility model realizes with following technical proposals:
A kind of engine oil pump combined driving device; Comprise live axle, oil pump impeller, mechanical driving mechanism and motor-driven mechanism in the formation; Said live axle one end is fixedly connected with the oil pump impeller, and said mechanical driving mechanism is made up of belt pulley and click apparatus, and the inboard symmetry of said belt pulley is installed two cover ratchets; Said ratchet and ratchet are equipped, and said ratchet is fixed on live axle one end.
Above-mentioned engine oil pump combined driving device; Said motor-driven mechanism is made up of motor, motor gear and axle shaft gear; Said motor is fastenedly connected through output shaft and motor gear, said motor gear and axle shaft gear engagement, and said axle shaft gear is fixed on the live axle.
Above-mentioned engine oil pump combined driving device also is provided with intelligent control system, and said intelligent control system is made up of oil temperature sensor and microprocessor, and they are electrically connected with motor control switch.
Live axle and mechanical driving mechanism broke away from fully when the click apparatus of the utility model through the belt pulley place guaranteed machine operation, had avoided the consumption of excess energy; Drive oil pump work through motor-driven mechanism, solved motor and shut down the machine oil carbonization problem that localized hyperthermia causes suddenly, the engine component of having avoided causing thus damages; Make motor be in good lubricated radiating state all the time through intelligentized control system, thereby prolong engine operational life.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the structural representation of the utility model.
Each label is among the figure: 1, belt pulley, 2, ratchet, 3, ratchet, 4, live axle, 5, axle shaft gear, 6, the oil pump impeller, 7, motor, 8, motor gear.
Embodiment
Referring to accompanying drawing; The utility model comprises live axle 4, oil pump impeller 6, mechanical driving mechanism and motor-driven mechanism in constituting; Said live axle 4 one ends are fixedly connected with oil pump impeller 6, and said mechanical driving mechanism is made up of belt pulley 1 and click apparatus, and the inboard symmetry of said belt pulley is installed two cover ratchets 2; Said ratchet 2 is equipped with ratchet 3, and said ratchet 3 is fixed on live axle 4 one ends.
Referring to accompanying drawing; Motor-driven mechanism during the utility model constitutes is made up of motor 7, motor gear 8 and axle shaft gear 5; Said motor 7 is fastenedly connected through output shaft and motor gear 8, said motor gear 8 and axle shaft gear 5 engagements, and said axle shaft gear 5 is fixed on the live axle 4.
Referring to accompanying drawing; The working principle of the utility model is: the power of mechanical driving mechanism is through belt pulley 1 (devices such as chain, gear) input by engine crankshaft; When normal working of engine; Belt pulley promotes ratchet 3 rotations through being installed in its inboard ratchet 2, and it is that motor provides machine oil lubricated and heat radiation that the live axle 4 that is fixedly connected with ratchet drives oil pump; The effect of motor-driven mechanism is: behind engine stoping operation; Drive live axle 4 and oil pump impeller 6 through motor 7; Make oil pump work, the ratchet in the mechanical driving mechanism rotates with live axle at this moment, and ratchet is as driving part in click apparatus; The Driving force of ratchet is disengaged, and belt pulley is in stop state.The unlatching of motor receives the control of oil temperature sensor, and when system's oil temperature was lower than setting value, oil pump quit work; The utility model adopts intelligentized control device, has guaranteed the timely heat radiation lubricating of motor, has prolonged the working life of motor, is specially adapted to the drive controlling of turbosupercharged engine oil pump.
