The invention relates to a method for maintaining total braking power of a rail vehicle while taking the available friction conditions into consideration. The method includes recognizing that at least one unit is wheel-slide controlled; retrieving the type of friction prevailing on the wheel-slide controlled units; determining the values 0 and K0 for each unit that is wheel-slide controlled; forming a function for the value 0 and a function for the value K0, in each case over the entire length of the units comparing the actual braking request in each of the units, to the function of the value K0, and changing each braking request in each of the units, towards the respective value of the function of K0.

A high-speed transportation with a transporter enveloped by low pressure in running tube includes a running tube, a running rail, a carrier structure, a control system, a braking system and a driving system. The running tube is an extended tube structure enveloped by a tube wall. A plurality of one-way airflow windows are provided on the tube wall, and the direction of airflow passing through the plurality of one-way airflow windows are controllable. The driving system includes a blocking-type running drive structure, a running blocking structure and a blocking-type running pressure-reducing structure which are provided in the running tube and run along the running tube. The carrier structure is a compartment structure. A connecting structure includes a flexible telescopic connecting structure and a rigid non-telescopic connecting structure.

Devices, systems, and methods are described that provide an braking system for a motor vehicle. The braking system extends a friction device from beneath the vehicle to contact the driving surface. Orientation of the friction device and forces applied to the braking device can be adjusted during the braking procedure.

In some braking devices forces generated during braking are directed to a load bearing arm and supporting frame, thereby minimizing damage to actuating devices. The friction device can be retracted after use, permitting normal vehicle operation.
