Problems solved by technology

Since a reliability test needs to be continued for a long time, and the failure of bearings or universal joints often occurs after a long period of heavy-load operation, once the existing two methods fail, it will cause serious damage to the reliability test. Great damage, seriously affecting the improvement of productivity, wasting a lot of energy and time

Embodiment Construction

[0019] The preferred specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0020] figure 1 and figure 2 Shown are all prior art, specifically:

[0021] figure 1 Shown is an existing engine power take-off (PTO) test connection device, which is used for reliability tests of large heavy-duty vehicle engines such as cement mixer trucks. This engine has two output ends, one is located at the bottom, that is, the engine connection plate 2; the other is located at the top, that is, the PTO output flange 1 of the engine. An elastic coupling 3 is connected to the engine connection plate 2, and then connected to a dynamometer 4 through a cardan shaft 5. The universal transmission shaft 5 is a short shaft with universal joints 6 at both ends, one of which is connected to the elastic coupl...

Abstract

The invention discloses an engine power output test connection device. The connection device is used for connecting a PTO (Power Take Off) output end of an engine and a dynamometer, and comprises two transition shafts and shaft coupling transmission equipment which is fixedly arranged on a test platform; one transition shaft is connected with the PTO output end of the engine and the input end of the shaft coupling transmission equipment; and the other transition shaft is connected with the output end of the shaft coupling transmission equipment and the input end of the dynamometer. Furthermore, the shaft coupling transmission equipment is a transition dynamometer for transmitting power. The connection device is the engine power output test connection device with reliability in operation and lower fault rate; and the requirements of an engine PTO reliability test can be met.

Description

technical field [0001] The invention relates to a connection device, in particular to a power output test connection device for a heavy-duty engine. Background technique [0002] In the reliability test of the engine, it is necessary to keep the engine running for a long time without interruption and heavy load, and detect the power output (that is, PTO, the abbreviation of Power Take Off) performance of the engine. This kind of detection needs to fix the engine on the experimental platform, and then connect the PTO output end of the engine to a special dynamometer device with a transition shaft for testing. In the engine reliability testing of large heavy-duty vehicles such as cement mixer trucks, since there are two output terminals of the engine, which are designed to be in up and down positions, and the upper one is the PTO output terminal, there are also two corresponding dynamometers, and Designed to be in an up and down position. However, limited by the size of the ...
