In the bench test method of present domestic manual transmission, also there is not clear and definite special test variator when running up, because the test method of the transmission of power that the variation of oil mass causes loss numerical value.
Summary of the invention
Problem to be solved by this invention provides a kind of method of testing power loss in high speed of automotive transmission, its objective is by this verification experimental verification variator running up down, because the size of the transmission of power that the variation of oil mass causes loss.
To achieve these goals, the technical scheme that the present invention takes is: the method for testing power loss in high speed of this automotive transmission that is provided, test specimen is the variator of automobile, its testing equipment is a variator operational test platform, this testing table is provided with dynamometer and oily temperature tester, and on this testing table, automotive transmission connects with the connecting mode of engine by the actual product assembling, test event is the output valve that the gentle variator of lubricating oil oil drives power, and the process of this test method is:
A) described variator adds the lubricating oil of regulation oil mass;
B) described engine start, and lose test condition by high speed and move continuously;
C) the lubricating oil oil mass slowly increases;
D) test oil temperature numerical value and variator drive the output valve of power;
Stop when e) extremely warm rapid rising of oil or driving power sharply change, and the record lubricating oil oil temperature at this moment and the output valve of variator driving power.
Variator power loss in high speed test condition recited above is:
A) gear: variator is set to the highest gear;
B) running speed: engine is with the highest output rotational speed rotation;
C) load: the output shaft of variator is zero load;
D) oil temperature; When the regulation oil mass, setting oily temperature is 140 ℃.
Above-described high speed loss test method is 120% of regulation oil mass to the ceiling value that variator increases oil mass.
The standard that the transmission of power loss of added oil mass of described variator and variator meets the demands is: in the oil mass scope of regulation oil mass+10%, zero load driving power sharply rises or the oil temperature does not sharply rise.
The output valve that the variator that described dynamometer shows drives power is the minimizing value of power transmission outputting power; Described zero load driving power sharply rises and is meant that the registration of dynamometer does not have rapid increase.
Described variator is set to the highest gear, is meant when variator is five speed transmission, and it is set to 5 grades; Engine is meant that with the highest output rotational speed rotation its throttle is set to maximal value.
Described lubricating oil oil mass slowly increases, and the speed of its oiling does not cause that the disturbance that variator drives the output valve of power is a limit value when refueling.
The present invention adopts technique scheme, the size of the transmission of power loss that the variation owing to oil mass of checking variator under running up causes, thereby can judge whether the added oil mass of variator is suitable when design, and in the high engine speed range of engine, whether the transmission loss of variator can satisfy the requirement of the economy of car load.
