Embodiment Construction

[0026] As shown in Fig. 1, what the present invention provides is a kind of high-speed power loss test method of automobile transmission, and this figure is the process block diagram of this method; What Fig. 2 shows is the test equipment that above-mentioned test method adopts and tested piece Structure.

[0027] The technical scheme that the present invention takes is: the high-speed power loss test method of this automotive transmission involved, the tested part is the transmission 3 of the automobile, and the test equipment of the described high-speed loss test is a transmission running test bench 1, and the test bench A dynamometer 5 and an oil temperature tester 4 are provided. On the test bench, the transmission 3 of the automobile and the engine 2 are connected according to the connection method of actual product assembly. The test items are the output value of lubricating oil temperature and transmission driving power. The procedure of the test method is:

Abstract

A method for testing high speed power loss of speed variator on automobile includes adding set amount of lubricating oil into speed variator, starting up engine and running engine continuously as per test condition, increasing amount of lubricating oil step by step slowly, measuring oil temperature and output value of driving power from speed variator continuously and stopping measurement till oil temperature or driving power output value is changed suddenly, recording temperature of lubricating oil and output valve of driving power from speed variator.

Description

technical field [0001] The present invention relates to automobile manufacturing technology, more specifically, the present invention relates to a kind of high-speed power loss test method of automobile transmission. Background technique [0002] The amount of lubricating oil added to the automobile transmission should be appropriate. Too little oil will affect the lubrication of the parts in the gearbox and accelerate the wear of the parts, thereby reducing the service life of the transmission assembly; The oil churning loss is increased, and its transmission efficiency is reduced. Especially in high-speed operation, the oil temperature will rise sharply, thereby reducing the service life of the transmission. Therefore, it is necessary to pass the high-speed loss test of the transmission to determine the appropriate amount of fuel. This test can verify the size of the power transmission loss of the transmission assembly under high-speed operation, so as to determine whethe...
