This brake patent does not cover real brakes on motorbikes, disc brakes on wheels, which are called service brakes in engineer speak. In this case, it has to do with an extra braking gadget that will be utilized when the automobile is fixed. Time for parking.
Parking brake and immobilizer
Parking brakes prevail on automobile, however not on bikes previously. Particularly for heavy motorbikes, it makes sense to safeguard them from rolling. Depending upon the weight of the vehicle and the gradient in the parking area, this can occur even with the equipment engaged. Which is twice as frustrating: initially when you need to get up once again, which takes a great deal of effort, and after that when you need to fix a crashed bike, which is costly.
Brake shoes or brake band on the drive shaft
Heavy devices from BMW typically have a cardan last drive. And this is precisely where the innovation patented by BMW worker Thomas Ringholz can be found in: It supplies an extra braking gadget on the cardan straight behind the transmission output. The drive shaft is totally surrounded by a brake gadget. The drive shaft can be struck “frictionally” with brake shoes or additionally with a brake band. Or rather: hold tight. This brake is not planned to be utilized while driving. At finest, it can be considered an emergency situation brake that works weakly while driving, for emergency situations when the so-called service brakes stop working.
Mechanical, electromechanical or automated
At the front here is the extra function of the parking brake, likewise called the parking brake. They can be triggered mechanically, ie by pulling a cable television or connection, each with a “parking block”. The brake shoes– or brake band– are hydraulically managed for low operating forces and high stopping power. Electric operation is likewise prepared, ie by pushing a button– or straight when the motorbike is fixed. Another function is the incorporated immobilizer function to avoid unapproved motion of the vehicle.
BMW R 18 with open drive shaft
The cruiser designs of the R 18 design series from BMW are set to utilize a brand-new radial parking brake. They are extremely heavy and each has just a side stand, no primary stand. And: With the R 18 designs, the drive shaft is open, which would make it much easier to change the trademarked brake gadget. Much like in the very first image from the patent application, which plainly reveals the environment understood from the R 18.
Maybe likewise with the brand-new BMW R 1300 GS
In concept, nevertheless, a cardan parking brake might likewise be created and set up in other designs in the future utilizing a totally confined cardan working on the rear wheel’s swing arm. This likewise uses to the much heavier K 1600 designs with six-cylinder engines, however likewise to the very popular GS and other designs with fighter engines and cardan shafts. Maybe particularly with the brand-new BMW R 1300 GS, which is anticipated in2023 The cardan brake can likewise be utilized as a security gadget in the occasion of cardanic problems– as currently mentioned in the patent application.
Automatic transmission and electrical drives
The topic of parking brakes to avoid rolling is really essential in cars with automated transmissions and in cars with electrical drives in basic. That is why most BMW motorbike designs, with the exception of the C 400 designs, are geared up with extra micro-brakes on the rear brake disc. This different brake caliper is triggered when the side position is set down– a smart service, however it includes unsprung mass to the rear wheel. For designs with a cardan last drive, this can be prevented by utilizing a brand-new patent brake.
Cardan brakes have actually been around prior to
Almost 100 years earlier, in the 1920 s, there were radial brakes on BMW motorbikes. On the BMW R 42– not as a parking brake, however as a “service brake”, ie for braking while driving. Cardan brakes were likewise often utilized on BMW bikes in racing.

Conclusion
Kadian brake from BMW– it was practically 100 years back, however as a parking brake it is a creation that appears to make good sense today. A growing number of with heavy designs without primary stop and later on designs with automated transmission or with an electrical motor. It is not yet understood if and when the Kadian parking brake will get in series production at BMW. Perhaps likewise with the brand-new BMW R 1300 GS, which is anticipated in 2023.
