Abstract

A connecting tool of a motor testing platform comprises a first coupler (8), a flange (7) and a stepped shaft (6), wherein the first coupler (8), the flange (7) and the stepped shaft (6) are sequentially connected with a measurement and control machine. The connecting tool of the motor testing platform is further provided with a fixed support (2) which is provided with a connecting portion (3), one end of the connecting portion (3) is connected with the stepped shaft (6), the other end of the connecting portion (3) is connected with a second coupler (1), the second coupler (1) is connected with a tested motor and divided into a fixed end (11) and a detachable movable end (12), and the movable end (12) is connected with the tested motor. The connecting tool of the motor testing platform can meet testing requirements on motors with different capacities, is convenient to replace, and is high in system concentricity, stable and capable of being widely applied to the field of motor testing platforms.

Description

Technical field [0001] The invention relates to a connection tool for a motor test bench. Background technique [0002] New energy vehicles, as a new force that is clean and pollution-free, and can save energy for human survival, have been increasingly favored by people, and many countries are sparing no effort in research and development. The electric drive system, which is the heart of new energy vehicles, is also developing rapidly in this tide. In particular, the diversification of motors has become the basis for different models. For example, the difference in motor capacity will be applied to different levels of car models. Due to the difference in capacity This will result in different radii of the motor output shafts. Therefore, only the development of the motor test bench connection tool for the same capacity is not only unsatisfactory for versatility, but also a waste. At the same time, due to the long distance between the measuring and controlling machine and the moto...
