DETAILED DESCRIPTION

The present disclosure relates to a vehicle component. The vehicle component may constitute a portion of a vehicle frame. The vehicle component may be a front fork or a rear fork, e.g. a front/rear fork of a bicycle, e-bike or motorcycle.


The vehicle component may be a(n individual) component that transfers (at least part of) a gravitational force acting on a payload of a vehicle to at least one (propulsive) element that interacts with an ambient environment of the vehicle, e.g. for the sake of providing a propulsive force and/or for the sake of allowing the vehicle to glide/roll over an ambient surface. The payload may include a driver, a rider and/or a passenger of the vehicle. The payload may include an inanimate payload. The ambient surface may be terrain. Similarly, the ambient surface may be a water surface, e.g. a surface of a body of water. The (propulsive) element may be a terrain-engaging element, e.g. a terrain-engaging element selected from the group consisting of a wheel, a skid, a ski and a (continuous) track. Similarly, the (propulsive) element may be a marine (propulsion) element, e.g. an element selected from the group consisting of a float, a hull, a water ski, a jet nozzle and a propeller. For the sake of conciseness, the term “terrain-engaging element” will be used hereinafter to designate any (propulsive) element as described hereinabove, regardless of whether such element is a marine element. (An elucidation of the term “any” is given in the closing paragraphs of this specification.) The vehicle may be a vehicle selected from the group consisting of a bicycle, an e-bike, a motorcycle, a moped, a (terrestrial) rover, a snowmobile, a snow scooter and a (personal) watercraft. As such, the vehicle may be a vehicle selected from the group consisting of a human-powered vehicle, a (gasoline and/or electric) motor-powered vehicle and a vehicle powered by both human and (gasoline and/or electric) motor power. In the context of the present disclosure, the term “e-bike” may be understood as a bicycle comprising an electrically powered motor that contributes a driving force to at least one wheel of the bicycle.

The tubular structure may be an arm of a fork, e.g. a front/rear fork of a bicycle, e-bike or motorcycle. The tubular structure may be a yoke portion of a fork, e.g. a front/rear fork of a bicycle, e-bike or motorcycle


The vehicle component may comprise/consist (substantially) of a first arm, a second arm and a yoke portion. Any of the first arm, the second arm and the yoke portion may be a tubular structure as described supra and may comprise an interior wall as described supra. Each of the first and second arms may comprise/define a receptacle, e.g. a dropout, opening or bore, (in a rearmost/lowermost 10% of the respective arm) that receives a (respective) end of an axle (of a wheel). A “rearmost”/“lowermost” region of the first/second arm may be understood as a region most distal from the yoke portion. The yoke portion may interconnect the first and second arms (at a (respective) forward/upper portion of each of the first and second arms). The fork may comprise a space between the first and second arms that accommodates a (forward/upper) portion of the wheel (as known in the art). The fork may be a monolithic/unitary structure. The fork may be termed a “swingarm”.


The yoke portion may comprise a cylindrical receptacle. The cylindrical receptacle may constitute a barrel of a slide link. Similarly, the yoke portion may form a piston of the slide link. The slide link may comprise a barrel and a piston (that slides at least partially within the barrel). The barrel may comprise a (circular) cylindrical inner wall. The piston may slide within the barrel along a (linear) slide axis. The piston may comprise a (circular) cylindrical outer wall, e.g. a cylindrical outer wall that (within tolerances as known in the art) matches (the dimensions of) the cylindrical inner wall of the barrel. The cylindrical outer wall of the piston may have a length of at least 10%, at least 20% or at least 30% of a length of the cylindrical inner wall of the barrel. The cylindrical outer wall of the piston may have a length of at most 40%, at most 30% or at most 20% of a length of the cylindrical inner wall of the barrel. The cylindrical outer wall of the piston may have a length of at least 5 cm or of at least 10 cm. The cylindrical outer wall of the piston may have a length of at most 10 cm or at most 20 cm. The length of the cylindrical outer wall of the piston and/or cylindrical inner wall of the barrel may be measured parallel to the slide axis. The cylindrical inner wall of the barrel may have a minimum dimension of at least 5 cm, at least 8 or at least 10 cm, e.g. as measured perpendicular to the slide axis (at the respective location). The cylindrical inner wall of the barrel may have a maximum dimension of at most 15 cm, at most 12 cm or at most 10 cm, e.g. as measured perpendicular to the slide axis (at the respective location). At least 80%, at least 90% or (substantially) an entirety of the slide link (by volume and/or by weight) may be a material selected from the group consisting of steel, aluminum and carbon fiber. Similarly, at least 80%, at least 90% or (substantially) an entirety of the barrel (by volume and/or by weight) may be a material selected from the group consisting of steel, aluminum and carbon fiber and at least 80%, at least 90% or (substantially) an entirety of the piston (by volume and/or by weight) may be a material selected from the group consisting of steel, aluminum and carbon fiber.


The yoke portion may be asymmetric relative to a (first) plane orthogonal to the second rotational axis (and midway between the receptacles of the first and second arms). As touched upon supra, the barrel/piston may comprise a circular cylindrical inner/outer wall. An axis of symmetry of the barrel/piston may be parallel to the (aforementioned first) plane. The axis of symmetry of the barrel/piston may be offset by at least 5 mm, at least 10 mm, at least 15 mm or at least 20 mm from the (aforementioned first) plane (in a direction away from the drivetrain). The vehicle component may constitute a chain stay, e.g. together with the remainder (e.g. barrel/piston) of the slide link not formed by the yoke portion. A chain stay may be understood as an element that supports a driving axis (e.g. a bottom bracket) relative to a driven axis (e.g. the axle axis), i.e. prevents the driven axis from being (unduly/catastrophically) pulled toward the driving axis as a result of a drivetrain force (e.g. the tension of a driven chain or belt). The chain stay may be an elevated chain stay. An elevated chain stay may be understood as a chain stay having a portion located higher (e.g. more distant from the terrain) than a drivetrain/chain of the vehicle. The chain stay may have the overall general shape of an arch and may comprise a central/elevated region. A bottom surface of (the central/elevated region of) the chain stay may be located at least 2 cm, at least 4 cm or at least 6 cm higher than the drivetrain. The central/elevated region may have a length of at least 10 cm, at least 15 cm or at least 20 cm. A forward/upper portion of the (respective) first/second arm may constitute the (respective) central/elevated region. An acute angle between the axis of symmetry of the barrel/piston and a longitudinal axis of the central region may be in the range of 30° to 60°. Similarly, an acute angle between the axis of symmetry of the barrel/piston and (a major surface of) the bottom surface of the central region may be in the range of 30° to 60°. The yoke portion may have a length of at least 10 cm, at least 15 cm or at least 20 cm, e.g. as measured in a direction parallel to at least one of a slide axis of the slide link and an axis of symmetry of the barrel.


The yoke portion may comprise at least one, at least two or at least four interior wall(s) that extends from an outer wall of the yoke portion to a wall forming the barrel. Any of the interior walls of the yoke portion may (longitudinally) divide a tubular (outer wall) structure of the yoke portion into a first tubular chamber and a second tubular chamber (e.g. as described supra). An angle between a respective major surface of any adjacent walls may be (substantially) equal to 360° divided by the total number of such walls (provided at a given cross-section (through the barrel and) orthogonal to at least one of a slide axis of the slide link and an axis of symmetry of the barrel). Any of the interior walls may have a (minimum) length, e.g. as measured parallel to a slide axis of the slide element or an axis of symmetry of the barrel, of at least 50% or at least 80% of a length of the barrel, e.g. as measured parallel to a slide axis of the slide element or an axis of symmetry of the barrel.


A first inner wall of the first arm that faces the second arm may comprise a first bulging region. Similarly, a second inner wall of the second arm that faces the first arm may comprise a second bulging region. The first bulging portion may protrude further in a direction of the second arm than an intermediate region of the first inner wall intermediate the bulging region and the yoke portion. The second bulging portion may protrude further in a direction of the first arm than an intermediate region of the second inner wall intermediate the bulging region and the yoke portion. The protruding of the first/second bulging portion may be in a direction orthogonal to the aforementioned (first) plane. The bulging region may protrude at least 4 mm, at least 6 mm or at least 8 mm further than the (respective) intermediate region. The bulging region may constitute at least 5%, at least 10%, at least 15% or at least 20% of an area of the (respective) inner wall. The bulging region may have a (generally) V-shaped cross-section in a plane orthogonal to a straight line from the axle axis to the yoke portion and orthogonal to the (aforementioned first) plane (through an apex of the bulging region). Similarly, the bulging region may have a (generally) V-shaped cross-section in a plane parallel to a straight line from the axle axis to the yoke portion and orthogonal to the (aforementioned first) plane (through an apex of the bulging region).


At least one of the first and second arm may comprise an interior wall that extends from an outer wall of the respective arm that faces away from the other arm to the (respective) first/second inner wall. The interior wall may (longitudinally) divide the respective first/second arm into a first tubular chamber and a second tubular chamber (e.g. as described supra). The interior wall may be substantially perpendicular to the outer wall. The interior wall may intersect the respective first/second inner wall at the apex of the (respective) first/second bulging region. The interior wall may extend over at least 60%, at least 80% or an entirety of a length of the bulging region, e.g. as measured in a longitudinal direction of the first/second arm and/or parallel to the interior wall. The apex of the bulging region may be located in a rearward/lower half or rearward/lower third of the central region. The bulging region may extend beyond the central region in a direction of the receptacles.


At least one of the first and second arm may comprise an opening that perforates the (respective) inner wall (of the first/second arm). The opening may have a diameter of no more than 6 mm, no more than 8 mm, no more than 10 mm or no more than 12 mm.
