Problems solved by technology

[0002] As national emission regulations become more and more stringent, domestic OEMs are beginning to develop small three-cylinder engines and small-displacement in-cylinder direct injection machines, because the inherent characteristics of three-cylinder engines and the large heat load of small direct injection machines will bring The problem of excessive vibration when coming to the bench test
Excessive vibration will not only affect the assessment and vibration measurement of the engine itself, but also affect the test equipment or even damage the test equipment

Embodiment Construction

[0012] With reference to the accompanying drawings, an engine test transmission vibration isolation device includes a support 10 on which a transmission mechanism 20 is connected, and the transmission mechanism 20 is driven by a belt. The core of the present invention is to add a belt transmission mechanism between the dynamometer and the engine, and use the vibration isolation effect of the belt transmission to weaken and block the vibration transmission when the dynamometer and the engine are rigidly connected, thereby reducing the impact of engine vibration on the engine. The impact of the bench test ensures the accuracy of data measurement, and also plays a good role in protecting test equipment such as dynamometers.

[0013] Further, the transmission mechanism 20 includes two parallel transmission shafts 21, one end of the two transmission shafts 21 is close to the middle position of the support 10, and the other end is arranged away from the middle position of the support...

Abstract

The invention discloses an engine test transmission vibration isolation device. The engine test transmission vibration isolation device comprises a support, wherein a transmission mechanism is connected to the support, and belt transmission is adopted by the transmission mechanism. Vibration transmission of rigid connection between a dynamometer and an engine is weakened and obstructed by utilizing the vibration isolation effect of belt transmission, the influence of external factors on the test effect is reduced, and the accuracy of measurement of test data of the engine bench test is guaranteed; and meanwhile, damage to test equipment such as dynamometer and the like caused by engine vibration is reduced, and the test equipment is effectively protected.

Description

technical field [0001] The invention relates to a tooling for an engine test room, and specifically designs a transmission vibration isolation device for an engine bench test. Background technique [0002] As the national emission regulations become more and more stringent, domestic OEMs are beginning to develop small three-cylinder engines and small-displacement in-cylinder direct injection machines, because the inherent characteristics of three-cylinder engines and the large heat load of small direct injection machines will bring The problem of excessive vibration when coming to the bench test. Excessive vibration will not only affect the assessment and vibration measurement of the engine itself, but also affect or even damage the test equipment. Therefore, the vibration of the transmission system of the engine bench test is an urgent problem to be solved by various manufacturers. Contents of the invention [0003] The object of the present invention is to provide an e...
