  • Patent number: 6141616
    Abstract: A wheel braking system for a motor vehicle includes sensors, controllable actuators, and an electronic control device for regulating the rpm of a vehicle wheel when an actual driving state of the vehicle differs from a specified desired driving state calculated as a function of the driving parameters, using a mathematical vehicle model. An automatic correction of the vehicle model, corresponding to a deviation of the desired driving state specified at the moment from the actual driving state at the moment, is performed during vehicle operation if an ideal driving condition exists. The ideal driving condition is a driving state in which it is known that no deviation that leads to regulation occurs. At least one condition is defined by which it is detected whether ideal driving condition exists.

  • Patent number: 5490582
    Abstract: A locking wheel chock, for positioning between adjacent tandem wheels on spaced axles of a vehicle having no independent braking system provides upper and lower pairs of wheel contacting blocks connected in spaced relationship by a telescoping body assembly. The telescoping body assembly carries a rack on one portion and a fastening lever with a partial pinion on the other portion to engage the rack to adjust the length of the body assembly to move the wheel blocks into and out of fastening engagement with the tandem wheels for preventing relative rotation. Each wheel block is independently pivoted to allow tangential contact with the adjacent tire tread. A lock prevents movement of the fastening lever to maintain positioning and prevent tampering with the wheel chock when the fastening lever is in fastening position. A first species of wheel block provides paired adjustably spaced blocks on each side of the center line of tandem wheels.

    Abstract: A compactor module is adapted to be attached to a tractor module to form a complete unit. Eight pneumatic tires support the rear portion of the compactor. An emergency or parking brake is attached to each compacting wheel. The brakes are interconnected by a continuous cable and pulley control system. All brakes are applied in unison when the cable tension in the control system is increased, due to the retraction of a piston rod of an air cylinder connected to one end of the cable. The rod retracts when the pressure in the air cylinder falls below a certain predetermined level. The rod projects outwardly when the pressure in the air cylinder returns above the predetermined level. The tension in the control system is relaxed when the air pressure in the cylinder again rises above the predetermined level, the rod returns to its extended position, and the brakes are substantially simultaneously released.

  • Patent number: 4169524
    Abstract: A disc brake service piston for heavy equipment and off-the-road vehicles has an annular configuration and is sealingly and reciprocably received in an annular cavity forming a pressure chamber. During brake disassembly requiring removal of the piston from the cavity, the piston must be disconnected from a series of piston retracting mechanisms. The arrangement permits the force of one piston retraction spring to be relieved at a time. A tool is used which has a thread at one end and a handle at the other end. The threaded end is inserted into a tapped hole at the end of a return spring guide pin which transmits the spring force of one retracting mechanism to the piston. The tool can then be moved to compress the guide pin spring so that the pin is moved a sufficient distance to expose a cross pin therein which provides the connection between the guide pin and the piston. The cross pins are removed, one by one, from all of the spring guide pins of all of the mechanisms.

In a second embodiment, the skate board wheel brake assembly includes the rear wheels and is attached to the rear end of a conventional skate board. In a third embodiment, the brake assembly is molded to be integral with the skate board.

  • Patent number: 3948333
    Abstract: Traction may be enhanced by jets of air which may be mounted in front and at the rear of the wheels of the automobile. Furthermore an embodiment of the present invention provides a means to support a single-wheeled vehicle in an upright position by directing jets of air against the roadway. The air from the jets being exhausted from nozzles in front and in the rear of the single-wheeled vehicle, whereby tilting of the singlewheeled vehicle forwardly or rearwardly while it is in motion is prevented.
