The key objectives of the new wheel hub are as follows:
‘bolt on’ feature.
The four holes within the central ‘ axle ‘ are shown above. These threaded holes allow a constant velocity housing to attach via fasteners rather than integrated into the rear hub. The knock-on effect is a smaller wheel hub and wheel bearings, reducing the size of the upright supporting the wheel hub and the weight of the USM. It also reduces the necessity of having a different geometry for the front and rear wheel hubs. Implementing this allows the UGRacing team to have all four wheel hubs almost identical, reducing manufacturing complexity.
Straight axle.
UGRacing team previously implemented a step in the wheel hub, requiring two different sized wheel bearings. After reflecting on the 2019 design, UGRacing found this of no benefit. It improved the ease of assembly, as a step in the axle meant the two bearings could simultaneously press onto their final seat. However, removing the step…
