Maintenance (oil change) inspection display in steering wheel hubs of motor vehicles and boats, or in the middle of the handlebars on motor cycles. Alternatively: separate instrument

摘要

The object of the invention described in more detail is to keep a close eye on these important maintenance and inspection dates with the corresponding mileages of the vehicle. This has a positive bearing on the safety of road transport. As is well known, safety can also only be achieved with the correct tyre pressure which can be read off from display windows inside the steering wheel hub. In the case of motor cycles the data referred to would be read off from an instrument fitted in the middle of the handlebars.
