Abstract
The invention discloses a system and a method for lubricating a crankshaft during the inclination of an engine, and belongs to the technical field of engine protection. When receiving a signal, an inclination angle sensor feeds back the signal to a controller, and the controller lubricates the crankshaft of the engine through an electromagnetic valve in real time according to the signal fed back by the inclination angle sensor. When a forward-backward or leftward-rightward inclination angle of the engine exceeds a certain angle such as 35 degrees, the electromagnetic valve is opened, an energy accumulator provides working pressure, and engine oil lubricates the crankshaft of the engine through an engine oil nozzle, so that the suction phenomenon of an engine oil pump can be avoided.
Description
Technical field
The present invention relates to motor resist technology field, relate in particular to the lubrication system and the method for a kind of motor bent axle when tilting.
Background technique
The engine crankshaft lubrication system generally is provided with oil sump, oil pump, oil injection nozzle and pipeline etc.; Not enough or before and after motor or inclination angle, the left and right sides when surpassing 35 ° when machine oil; Oil pump is inhaled less than the machine oil in the oil sump, emptying phenomenon occurs, can cause the engine crankshaft inordinate wear like this.
Summary of the invention
The lubrication system and the method for bent axle when providing a kind of motor to tilt at present; Through mounted angle sensor on motor; In the machine oil pipeline, be provided with solenoid valve and accumulator; And control with controller, can effectively solve the emptying phenomenon that causes when motor front and back or inclination angle, the left and right sides surpass 35 °.
Specifically realize through following technical proposals:
The lubrication system of bent axle when a kind of motor tilts; Wherein, Comprise and be installed in the dip sensor on the motor and be arranged on interconnective solenoid valve and accumulator in the machine oil pipeline; Said dip sensor, said solenoid valve are connected with a controller respectively, and said solenoid valve is between the oil pump and oil injection nozzle of motor, and said oil injection nozzle is over against engine crankshaft.
Preferably, the normal operating pressure of said accumulator is 0.4MPa.
The lubricating method of bent axle when technique scheme also discloses a kind of as above-mentioned motor inclination; Wherein, after dip sensor receives signal, give controller with signal feed back; Controller is lubricated engine crankshaft through solenoid valve according to the signal of dip sensor feedback in real time;
If inclination angle theta is less than pre-set threshold, the machine oil pipe is extracted the machine oil in the oil sump out under the effect of oil pump, through the direct lubricating engine bent axle of oil injection nozzle; If inclination angle theta is more than or equal to above-mentioned pre-set threshold, solenoid valve is opened, and accumulator provides pressure, through oil injection nozzle splash lubrication engine crankshaft.
Preferably, said pre-set threshold is 35 °.
Preferably, the normal operating pressure of said accumulator is 0.4MPa.
The beneficial effect or the advantage applies of technique scheme exist:
Through mounted angle sensor on motor, in the machine oil pipeline, be provided with solenoid valve and accumulator, and control with controller, can effectively solve the emptying phenomenon that causes when motor front and back or inclination angle, the left and right sides surpass 35 °.
