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, and a transmission mechanism 20 is connected to the support 10, and the transmission mechanism 20 is driven by a belt. The core of the invention is to add a belt drive mechanism between the dynamometer and the engine, and use the vibration isolation effect of the belt drive 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 influence of the bench test ensures the accuracy of the data measurement, and also plays a good role in protecting the test equipment such as the dynamometer.

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

Abstract

The invention discloses an engine test transmission vibration isolation device, which comprises a support, a transmission mechanism is connected to the support, and the transmission mechanism is driven by a belt. The vibration isolation effect of the belt drive is used to weaken and block the vibration transmission during the rigid connection between the dynamometer and the engine, reduce the influence of external factors on the test effect, ensure the accuracy of the engine bench test data measurement, and reduce the engine bench test data. The damage caused by vibration to test equipment such as dynamometer effectively protects the test equipment.

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] With the stricter and stricter national emission regulations, domestic OEMs have begun 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 engine bench test transmission system is an urgent problem to be solved by the manufacturers. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an engine test transmissi...
