Abstract
The utility model discloses an engine crankcase and an engine of the engine crankcase. The engine crankcase comprises a crankcase body and a disk cover, wherein a tensioning rod is arranged on the crankcase body, and an oil blocking part used for blocking engine oil from spurting is arranged on an oil inlet hole of the tensioning rod. According to the engine crankcase, due to the fact that the oil blocking part is arranged on the oil inlet hole of the tensioning rod, in the running process of the engine, the engine oil is blocked by the oil blocking part when making spurting movement along with rotation of a crankshaft, part of the engine oil is accumulated below the oil blocking part, and therefore an oil storage structure specially used by the tensioning device is formed, the engine oil flows into the tensioning rod along with opening of a check valve in the tensioning rod, a hydraulic system is stimulated to push the tensioning rod to move, and a timing chain is tensioned; the oil blocking part can guarantee that engine oil supplying in the tensioning rod is sufficient, and therefore tensioning pressure is guaranteed, the problem that the tensioning device loses efficacy because the engine oil in the tensioning rod is insufficient is effectively solved, and the tensioning device is higher in reliability and durability.
Description
Technical field
The utility model relates to a kind of engine components and motor, particularly a kind of engine crankcase and installed the motor of this crankcase.
Background technique
The necessary tensioning of timing chain of motor, just can make wheel shaft drive valve to open and close in the correct time, fitting piston completes stroke, and valve is opened too early or excessively closed evening and all can cause the faults such as motor excessive fuel consumption, unable, pinking, also can make valve and up piston collisions and damage motor.In order to make timing chain all the time in best tensioning state, tension device has all been installed in crankcase, can automatically to timing chain, carry out the adjusting of rate of tension.Existing tension device generally comprises nutted rod for tensioning pressure is provided, for tension arms and the Idle wheel for directly contacting with timing chain of transmission.Wherein, be provided with spring in nutted rod, the top of spring handle nutted rod withstands on tension arms, thereby passes to Idle wheel tensioning timing chain by tension arms.But only relying on the elastic force that spring-compressed produces is to form suitable tension force, so the nutted rod coupling together with crankcase is designed to a hydraulic pressure installation.Nutted rod is provided with oil inlet hole and the one-way valve entering for engine motor oil, after timing chain is loosening, and one-way valve conducting, machine oil enters the bottom of nutted rod, promotes hydraulic system to promote nutted rod motion, makes timing chain tensioning.
In prior art, nutted rod is generally arranged in the crankcase of motor, on nutted rod, have an above oil inlet hole, because oil inlet hole lacks special oil-bearing structure around, in engine operation process, engine motor oil can only enter oil inlet hole along with the motion random that splashes, the engine oil quantity not only entering does not guarantee, and the machine oil entering may be thrown out of because of other parts high speed rotary motion, cause nutted rod inner engine oil not enough, the tensioning pressure of generation is not enough, tensioning mechanism lost efficacy.
Therefore, be necessary existing engine crankcase to improve, make it be provided with the special oil-bearing structure for tension device, guarantee that nutted rod inner engine oil is sufficient, thereby assurance tensioning pressure, effectively solve the tension device Problem of Failure causing because of nutted rod hole inner engine oil deficiency, make tension device reliability, durability higher, and implement convenient, simple in structure.
