VEHICLE HUB RESTRAINT SYSTEM FOR A CHASSIS DYNAMOMETER

The former method of restraining a vehicle for dynamometer testing required chain falls that hooked into underbody hard points. Most vehicle manufactures are moving towards flat underbodies, which drove the requirement for a hub restraint system.

​

This system was designed to use minimal tools for vehicle installation, making use of pins instead of fasteners. This allows for expedited vehicle exchanges. The arms are telescoping stainless steel turnbuckles, pinned at each end. The lower yoke (pictured) derives its strength from being clamped against the steel floor. The clamping force is generated from the large base.
