The utility model has the advantages of convenient operation, reliable working, high precision, more particularly the short verification periodicity can greatly decrease the development cost, is particularly suitable for determining the valve timing of internal combustion engine on trial.
Description
One, technical field
The utility model relates to a kind of testing apparatus of motorcycle part, specifically a kind of device that is used for determining the IC engine gas distribution phase place.
Two, background technique
In the internal combustion (IC) Engine Design process, after determining according to the valve lift value of targeted the subject of knowledge and the object of knowledge decision, the lift of valve actuating mechanism camshaft is easy to determine according to the rocking arm ratio, but intake valve advance angle and intake valve lag angle, exhaust valve advance angle and exhaust valve lag the angle determine but very difficult, and it is quite complicated, at present, often need finally to determine by a large amount of engine performance tests.Usually at first set out several different camshaft phase schemes according to design experiences and limited calculating, utilize pattern method or form cutting to process camshaft then respectively, carry out verification experimental verification at last and determine that the shortcoming of this method is: have high input, the development cost height, the construction cycle is long.
Three, summary of the invention
The purpose of this utility model provides a kind of device that can determine the IC engine gas distribution phase place economic, convenient, accurately and quickly.
The purpose of this utility model is achieved like this: a kind of device that is used for determining the IC engine gas distribution phase place, and it is characterized in that: it comprises mandrel, timing sprocket, intake cam, exhaust cam and two rolling bearings; Described mandrel is installed on the camshaft fixed base of cylinder head by two rolling bearings; Described timing sprocket is fixed on a side end of mandrel, the mark when which is provided with cylinder piston and being in top dead center position; Intake cam and exhaust cam are fixed on the mandrel by the fastening screw trip bolt that can change cam installation phase place, and intake cam and exhaust cam are separately fixed at and inlet valve rocker and the corresponding position of exhaust valve rocker arm by the axial limiting piece.
For intake cam and exhaust cam can be fixedly mounted on the mandrel, described fastening screw trip bolt is arranged on cam rise place of intake cam and exhaust cam.According to the driving force of motor orchestration mechanism, be identified for the power that tightens of fastening cam special screw, process screw thread in cam rise place, cam is fastening with screw.
Install for convenient, realize the axially locating of intake cam and rolling bearing better, described mandrel is provided with the shaft shoulder that is used for installing intake cam and rolling bearing, and the another rolling bearing can be installed in the end side of mandrel.
When carrying out engine performance test, need verify the phase place of cam according to the diverse location of intake cam and exhaust cam, thereby obtain best port timing.After a state finishes, unclamp the screw of fastening cam, rotate intake cam and exhaust cam respectively to the desired location that needs checking, be screwed again, make a service test then, finally just can determine best port timing for several times so repeatedly.
Compared with prior art, be Spielpassung with intake cam and exhaust cam and mandrel in the utility model, promptly can rotate with respect to mandrel, at different states, intake cam and exhaust cam are in different phase places, finally obtain best port timing, the testing apparatus of this definite IC engine gas distribution phase place can be used on the various motors by the camshaft actuated distribution device.Its advantage is: easy to operate, the reliable operation of this device, the precision height verifies that particularly setting cycle is short, can reduce development cost greatly.
