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.

A railway vehicle, including an emergency braking device including at least one brake module, wherein each module includes a contact element intended to be in contact with the ground at the moment of braking, and movable between a retracted position and a deployed position in which the contact element is in contact with the ground and is able to slow down the moving railway vehicle by applying a pressure force to the ground, and at least one control unit that is capable of communicating commands to the brake module, wherein the control unit is able to communicate to the brake module the command to deploy the contact element to its deployed position when at least a portion of the vehicle leaves the track on which the vehicle is traveling.

A braking system includes a frame, an actuator coupled to the frame, a rotating joint coupled to the actuator and the frame, an arm coupled to the rotating joint, a brake pad having a connector, the connector pivotably coupled to the arm, and a torsion spring positioned at the connector to bias the brake pad relative to the arm.

Road vehicle comprising: a frame provided with a plurality of metal elements interconnected with one another; at least one drive wheel; at least one electric motor connected to the drive wheel; an electronic power converter, which controls the electric motor; and a dissipator device that is connected to the electronic power converter, is configured to dissipate electrical energy and comprises an expendable body that undergoes an endothermic transformation when an electric current flows through it.

A braking device for a vehicle includes a track, a brake pad, and a bar. The track is configured to couple to an underside of the vehicle. The track includes a stopping feature disposed along a length thereof. The bar has a first end in engagement with the track and an opposing second end coupled to the brake pad. The first end of the bar moves along the track and selectively engages with the stopping feature. The stopping feature permits movement of the first end of the bar in a first direction along the track but inhibits or selectively inhibits movement of the first end of the bar in an opposing second direction along the track.
