Electric vehicle wheel hub cover bolt tension test tool

Abstract

The utility model belongs to electric motor car accessory production technical field, concretely relates to a kind of electric motor car hub cover bolt tension test tool, including placing plate, the upper surface of placing plate is overlapped with hub bottom surface, multiple hub bolts are installed on the hub.The utility model is by the multiple pull rods of axial uniform distribution, make the hub bolt to be measured be pulled in synchronism on its actual installation circumferential position, perfect reproduction its real layout and constraint condition on hub, when using, bolt can be according to the assembly position on hub and be pulled to measure, to accurately simulate the stress condition of hub bolt everywhere, and device is in use, using positioning column is positioned to hub center, then all hub bolts are pulled tight synchronously by the multiple pull rods of axial uniform distribution, ensure that the loading force of tension testing machine passes through hub center, eccentric load is effectively avoided, and test data is accurate and reliable.
