SM25T Posted December 19, 2021 Share Posted December 19, 2021 Think about it ... look at the way the driveshafts turn when driving forwards ... you want them to tighten the hub nuts. Link to comment Share on other sites More sharing options...

aerobod - near CYYC Posted December 19, 2021 Share Posted December 19, 2021 In reality, there is no need for opposite threaded hub nuts and it can be argued they are the wrong way round. The most torque difference between the drive shaft and hub is caused by the friction at the tyre opposing the torque applied while accelerating. On the right hand wheel the clockwise driveshaft rotation is opposed by the relative anticlockwise hub rotation, therefore the friction of the nut face against the hub face causes the nut to be rotated anti clockwise relative to the axle. The axle splines only allow this very small fretting movement, though, so it is inconsequential in reducing the clamping torque of the nut.Basically there is no rational reason to have the hub nuts handed, especially in the way they are on the Caterham and not found on any modern car that I know of for driveshaft hub nuts or bolts.

Member Jonathan Kay Posted December 19, 2021 Member Share Posted December 19, 2021 Have you seen the Founder's explanation... but on centre-locked wheels?Jonathan Link to comment Share on other sites More sharing options...
aerobod - near CYYC Posted December 19, 2021 Share Posted December 19, 2021 Hi Jonathan, I think the original rational for spinners on centre lock wheels was relating to the higher braking forces, but the brake rotor forces are reacted through the wheel nuts, not the hub nut / spinner on our cars, so I don't think the Founder's principles apply to the current design.

Member Jonathan Kay Posted December 19, 2021 Member Share Posted December 19, 2021 Yes, it's different. But his approach to explanation was interesting. : - )Jonathan Link to comment Share on other sites More sharing options...
