A patient support apparatus includes a base having a length and including a plurality of caster wheels enabling movement of the patient support apparatus across a floor surface. An auxiliary wheel support structure is secured to the base and rotatably supports at least one non-castered auxiliary wheel. A drive mechanism including a motor may be configured to drive the auxiliary wheel. A braking system including at least one brake member may be configured to apply a braking force to decelerate the auxiliary wheel and is movable between a first position wherein the at least one brake member is disengaged from the auxiliary wheel and a deployed position wherein the at least one brake member is frictionally engaged with the auxiliary wheel to restrict rotation of the auxiliary wheel. The braking system may be configured to synchronize the braking forces applied to first and second auxiliary wheels.

Aspects hereof relate to a stand-on terrain working vehicle having a foot-operated parking brake system. The parking brake system includes a pedal assembly having a first pedal and a second pedal, an actuator coupled to the pedal assembly, a brake configured to be actuated between a set/engaged state and a released/disengaged state, and an over-center linkage. When the first pedal of the pedal assembly is depressed, the brake is actuated to the set/engaged state, and when the second pedal of the pedal assembly is depressed, the brake is actuated to the released/disengaged state. The over-center linkage is configured to bias the brake towards one of the set/engaged state and the released/disengaged state.

A motorcycle brake pedal lever includes a rod connected to a motorcycle and a base is connected to the rod. The base includes a bore. A pivotal member includes a first pivot and a second pivot extending toward different directions. The first pivot is pivotably connected to the bore of the base so that the pivotal member is pivotable about the first pivot. A peg includes a space formed therein, and the second pivot of the pivotal member is pivotably engaged with the space by a pin so that the peg is pivotable about pin and the second pivot. Multiple torsion springs are respectively mounted to the first and second. The torsion springs respectively contact the pivotal member, the base and the peg. The peg is returned relative to the pivotal member, and the pivotal member is returned relative to the base by the torsion springs.

Systems and device configurations are provided for reducing misstep, such as miscommunication between a vehicle and a driver that results in applying the incorrect pedal. Vehicle pedal configurations having a positioning element are described. Embodiments include pedal configurations having a pedal pad and at least one positioning element to adjust the pedal pad in response to pedal misstep.

A pneumatic brake pedal module for a “brake-by-wire” brake system of a vehicle is disclosed. The brake pedal module has a pivotably mounted brake pedal and having a damping unit, which is mechanically coupled to the brake pedal to generate a resistance when the brake pedal is actuated, such that the damping unit is subjected to tension when the brake pedal is actuated.

A pneumatic brake pedal module for a brake-by-wire brake system of a vehicle is disclosed. The brake pedal module includes a pivotably mounted brake pedal and a damping unit. The damping unit is mechanically coupled to the brake pedal to generate a resistance when the brake pedal is actuated. The damping unit comprises a housing and a piston, which is mounted movably in the housing and divides an internal space of the housing into a pressure chamber and a vacuum chamber. The pressure chamber and the vacuum chamber are connected to one another in terms of flow. The piston has on its running surface an encircling annular space in which a ring seal is accommodated in an axially movable manner. The ring seal is located at least in a flow path between the pressure chamber and the vacuum chamber and forms a restrictor in the at least one flow path, which restrictor frees different flow cross sections in the at least one flow path depending on the axial direction of movement, and damps the movement of the piston with differing degrees of strength depending on a direction of movement of the piston.

A brake pedal module for a brake-by-wire brake system of a vehicle is disclosed, having a carrier component for securing the brake pedal module on the vehicle, a brake pedal pivotably mounted on the carrier component, and a damping unit for producing a resistance during actuation of the brake pedal. The damping unit has an insert, which comprises at least one elastic element.
