Abstract

The invention relates to testing equipment, in particular to a flywheel-adjustable device of an automobile dynamometer. An adjustable flywheel (6) sleeves a shaft (4) on the left side or the right side of a fixed flywheel (5); an adjustable flywheel connecting bolt (7) penetrates through a hole in the adjustable flywheel (6) from the left side or the right side to be meshed with the thread in a hole in the fixed flywheel (5). The adjustability of an inertia flywheel is improved, the device dissembling difficulty is alleviated, and the security reliability of the device is improved.

Description

technical field [0001] The patent of the present invention relates to testing equipment, especially the flywheel adjustable device of automobile dynamometer. Background technique [0002] It is used for testing automobile dynamometer inertial simulation loading test. The inertial flywheel device for automobile dynamometer is used, and an integral flywheel structure is adopted. The inertia of this structure is constant and cannot be changed; The test disassembly is complicated, the safety is poor, and the inertia cannot be adjusted, which is increasingly unable to meet the needs of modern industrial development. Contents of the invention [0003] In view of the above problems, on the basis of the existing device, the original independent integral flywheel is changed into a plurality of flywheel groups connected in series, so that the weight of the flywheel can be changed, so that the inertia of the flywheel can be adjusted, reducing the time required for flywheel tests with...
