A vehicle, such as a rail vehicle, has an electrodynamic braking apparatus with at least one brake resistor. The at least one brake resistor forms a portion of the vehicle body shell that is permanently closed and over which air flows on the exterior, in particular, during travel of the vehicle. In the alternative, the brake resistor is arranged in the immediate vicinity of the permanently closed portion. The brake resistor conducts away heat outwardly to the environment via the permanently closed portion. There is also described a brake resistor for a vehicle, in particular for a rail vehicle, which is configured accordingly.

The reducer includes a screw, threaded internal rollers, and a tapped internal casing. The internal rollers each being in mesh firstly with the screw and secondly with the internal casing by means of at least one thread of opposite hand to a thread of the screw and of the same hand as a thread of the internal casing. The reducer further includes a tapped external casing and external rollers each in mesh firstly with the internal casing and secondly with the external casing. The external rollers are provided with at least one thread of opposite hand to a thread of the internal casing and of the same hand as a thread of the external casing.

A multidirectional wheel system, apparatus, and method to control one or more multidirectional wheels to provide multidirectional motion or movement for a movable apparatus, such as a skateboard, roller blades, a car, a motorcycle, a cleaning robot, to which the one or more multidirectional wheels are attached. The multidirectional wheel system includes a braking system to slow and/or stop the movement of the multidirectional wheel(s). At least one of the multidirectional wheels is an omnidirectional wheel, with a plurality of multidirectional wheels acting thereon to control movement thereof. The multidirectional wheel system includes a drone, wherein the omnidirectional wheel operates based on instructions from the drone.

A method for braking a vehicle, which is moving along a carriageway, by a braking device which has at least one friction brake and at least one regenerative brake for braking at least one wheel of the vehicle, wherein an anti-lock braking operation is carried out by the braking device, at least one braking torque which is to be applied to the wheel by the braking device being at least temporarily limited to a prespecifiable value by a regulating device of the vehicle during the anti-lock braking operation to at least temporarily prevent locking of the wheel relative to the carriageway, wherein the braking torque for braking the wheel is applied to the wheel at least partially by the regenerative brake at least during a portion of the anti-lock braking operation, and also to a vehicle which executes the disclosed method.

A brake gear motor (1) comprising an electric motor (2) having a motor shaft (3); a reducer (4) operatively connected, with its input side (9), to said motor shaft (3), to receive a movement and a driving torque and transmit them with its side output (10) to the brake; a housing (5) having at least one chamber (6, 28, 29); said at least one chamber (6, 28, 29) being at least partly delimited by at least one chamber wall or mantle (7) wherein a support plate (8) is provided in said housing; said motor (2) is accommodated, at least in part, in said at least one chamber (6, 28, 29); said motor shaft (3) is supported freely rotatable in said support plate (8); said reducer (4) is accommodated in said at least one chamber (6, 28, 29); said reducer (4) is supported freely rotatable in said support plate (8); said housing (5) comprises a connection rim to the brake (11) suitable to couple said housing (5) to a brake calliper (12) so as to interface with said output side (10) of the brake and allow the movement of at least one brake pad (13) towards and away from a disc brake disc (14) and exert a braking action; and in which said support plate (8) divides said housing in three chambers (6, 28, 29), a first chamber (6) accommodates the output side (10) of the reducer (4), a second chamber (28) houses at least a part of the electric motor (2), a third chamber (29) houses the input side (9) of the reducer (4) or side of the reducer connected to the electric motor (2), wherein said second chamber (28) is closed by a first cover (40) substantially cup-shaped, selected from a set of cup-shaped covers, that forms a first cover compartment (46) of a predefined size and suitable for housing a portion of a specific size of electric motor (2), in order to adapt said brake gear motor group (1) to different applications, by changing only said first cover (40) in said of first covers, and keeping the housing (5) unchanged.

A spoke for a wheel can include a first end, a second end, and an attachment section therebetween, the first end and the second end extend at an acute angle with respect to each other, the attachment section including a non-circular portion in cross-section.
