Embodiment Construction

[0009] The invention provides a multi-stage shifting flywheel device for a railway locomotive vehicle test bench. The multi-stage shifting flywheel device includes a flywheel shaft 1, a shift mechanism 4 and a box body 5. The multi-stage shifting flywheel device realizes the combination of multiple flywheel shafts 1 through the shift mechanism 4, and meets the speed regulation requirements of the dynamometer motors of the vehicle test bench during the test process of locomotives of different power levels.

[0010] As shown in the figure, the flywheel shaft 1 is installed in the box body 5. There are at least two flywheel shafts 1. Each flywheel shaft 1 is installed coaxially in sequence. The middle part of the flywheel shaft 1 is disc-shaped, and the two ends of the flywheel shaft 1 are It is used to install the shaft body of the positioning bearing. There is a shifting mechanism 4 between the flywheel shafts 1. The multi-stage gear shifting flywheel device realizes the combina...

Abstract

The invention discloses a multi-stage shift flywheel device for a test rig of a railway locomotive, and the multi-stage shift flywheel device comprises at least two flywheel shafts arranged in a box body, wherein the flywheel shafts are sequentially and coaxially arranged, and the middle part of each flywheel shaft is in a circular disc shape; and the two end parts of the flywheel shafts are shaft bodies for installing positioning bearings, and a gearshift is arranged between the two flywheel shafts and is used for realizing the combination of the flywheel shafts and meeting the speed adjustment requirements of a power-measuring motor of the test rig in the test process of the locomotives of different power levels. The problem that the difference in the moment of inertia of the flywheels needs to be realized when the tested locomotives have greater difference in different power levels and speed levels can be solved, and different moment of inertia of the flywheels can be obtained by the combination of different numbers of flywheel shafts so as to meet the test requirements of various locomotives. The multi-stage shift flywheel device is suitable for the test rig of the railway locomotive, and has the advantages of simpleness and easiness in implementation, safety and reliability, strong generality, and wide application range.

Description

technical field [0001] The invention relates to the technical field of railway locomotives, in particular to a multi-stage shifting flywheel device applied to a railway locomotive vehicle test bench. Background technique [0002] In order to adapt to the test of locomotives with different power levels and speed levels, the railway locomotive test bench requires different moments of inertia for the flywheel device used to stabilize the speed and store energy. For different locomotives, different flywheel devices need to be processed and stored, which not only causes waste of processing and raw material costs, but also brings pressure on equipment storage. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a multi-stage shifting flywheel device which can be tested by using different grades of locomotives. [0004] The technical solution adopted by the present invention is that the multi-stage shifting flywheel device include...
