Skateboard trucks and skateboards using the improved trucks are disclosed. Truck according to the present invention can comprising a hanger with wheels. A base assembly is included having an at least partially hollow housing section. The hanger is rotationally mounted to the base assembly. The hanger also comprises a hanger portion that is within partially hollow housing section. Compressible spring elements are included within the partially hollow housing section, wherein the hanger portion operates on the compressible spring elements when the hanger rotates in relation to the base assembly. Skateboard are also disclosed that utilize the truck. One or more trucks are mounted to the skateboard deck with the truck having internal compressible spring elements that are compressed when turning the skateboard. The internal compressible spring elements also expand to return the truck to a neutral position when the skateboard is not turning.

A skateboard truck includes a metal bolt called a kingpin and a threaded fastener, called a hex nut, which when combined hold the two main components of a truck together: the baseplate, which is mounted to the bottom surface of the skateboard deck; and the turning part of the truck called the hanger, which is mounted onto the baseplate by means of the kingpin, and affixed tightly into the baseplate by means of a threaded shaft nut assembly permanently affixed within the baseplate. Two bushings placed along the shaft of the kingpin and on either side of a flange protruding from the hanger hold the hanger in place by the tightening of the kingpin into the threaded shaft nut fastener. The kingpin is oriented such that a threaded portion of the kingpin (on an end opposite a bolt head portion) is generally facing towards a bottom surface of the skateboard deck.

A rotation powered vehicle drive mechanism includes an elongated chassis slot disposed within a respective lateral exterior portion of a chassis assembly. An elongated platform slot is disposed within a respective lateral portion of a platform assembly, and is configured such that it is substantially opposed to the chassis slot. The platform assembly is pivotally secured to the chassis assembly thereby allowing for rotation through a platform rotation angle of the platform assembly with respect to the chassis assembly about a rotation axis. The rotation of the platform assembly results in an increase or decrease of a variable slot height which is measured between the chassis slot and the platform slot. A cart assembly is disposed between the chassis assembly and the platform assembly, and is operatively coupled to the chassis slot and to the platform slot. The cart assembly has a cart height and is constrained by the chassis slot and the platform slot to a position on the chassis assembly wherein the cart height is substantially equivalent to the variable slot height. In this manner the cart assembly is configured to translate along the chassis assembly upon rotation of the platform assembly with respect to the chassis assembly. A helical drive shaft is rotationally secured within the chassis assembly and operatively coupled to the cart assembly such that translation of the cart assembly results in rotational motion of the helical drive shaft. A truck assembly is pivotally secured to the chassis assembly. The truck assembly includes an axle rotationally secured to the truck assembly and operatively coupled to a plurality of wheels. The axle is operatively coupled to the helical drive shaft such that rotation of the platform assembly with respect to the chassis assembly in a first angular direction results in rotation of the axle and respective wheels in the first angular direction.

An electric skateboard has a frame assembly that includes a deck with an opening of the deck to house a battery case mounted to a bottom of the deck. The frame includes a top plate that covers the opening and forms with the battery case an enclosure. A battery pack is positioned in at least partially in the enclosure. Front and a rear trucks are mounted to the bottom of the deck. At least one of the first and front and rear trunks is coupled to first and second wheels mounted on axles of the front and rear trucks. The front truck is mounted on the front end and a rear truck is mounted on rear end of the deck. First and second wheels are powered by one motor with a differential and a shaft coupled to the first and second wheel. The motor is coupled to the shaft to rotate the first and second wheels. The motor is electrically connected to the battery pack through a rear channel. The motor rotates the first and second wheels in the same directions and propels the electric skateboard forward and backward.

The utility model relates to the field of skateboard fitting, specifically relating to an adapter for surfskate comprising a fixing plate, a rotating plate, an centre shaft screw and a locking nut wherein said fixing plate and rotating plate link together via centre shaft screw and locking nut; a torsion spring is sleeved on centre shaft screw between fixing plate and rotating plate, and the top of torsion spring is fixed on fixing plate, and the bottom is fixed on rotating plate; said centre shaft screw located on top and bottom of rotating plate are sleeved with a thrust bearing wherein thrust bearing on the top of rotating plate is provided within torsion spring; on the side of fixing plate closing to rotating plate is equipped with limiting groove and on the side of rotating plate closing to fixing plate is equipped with limiting block matching with limiting groove.

A skateboard truck includes a metal bolt called a kingpin and a threaded fastener, called a hex nut, which when combined hold the two main components of a truck together: the baseplate, which is mounted to the bottom surface of the skateboard deck; and the turning part of the truck called the hanger, which is mounted onto the baseplate by means of the kingpin, and affixed tightly into the baseplate by means of a threaded hex nut. Two bushings placed along the shaft of the kingpin and on either side of a flange protruding from the hanger hold the hanger in place by the tightening of the kingpin into the threaded shaft nut fastener. The kingpin is oriented such that a threaded portion of the kingpin (on an end opposite a bolt head portion) is generally facing towards a bottom surface of the skateboard deck.

A braking system having a rotating element that rotates about an axis, and a braking device for braking the rotating element. The braking device has a first braking element that is movable between a rest position and a braking position and has an annular braking surface which is arranged concentrically with respect to the axis and has a brake disc which is co-rotationally connected to the rotating element and has first and second frictional surfaces. The annular braking surface of the first braking element is arranged at a distance from the brake disc in the rest position, and is in contact with the first frictional surface thereof in the braking position. A second braking element is arranged such that in the braking position the first braking element presses the brake disc against the second braking element such that the second braking element is in contact with the second frictional surface.

A skateboard axle assembly is described, having a connection plate for mounting the axle assembly to a skateboard deck and a wheel axle. The wheel axle has two ends, to each of which a wheel can be mounted. The wheel axle is movably coupled to the connection plate by two articulated arms. In addition, a skateboard having at least one skateboard axle assembly is described.

In one aspect, a modular board exercise system includes a skateboard. The skateboard includes a deck. The deck includes a plurality of hookable portions, and a pair of skateboard trucks coupled with a bottom side of the deck. The skateboard truck includes a pair of skateboard wheels. The system includes a plurality of resistance bands includes an elastic resistance band, a handle coupled with the distal end of the elastic resistance band, and a connecter clip coupled with the proximate end of the elastic resistance band. The connecter clip is attachable to one of the hookable portions. The system includes a stopper base. The stopper base includes a flat pad including a flat pad with a pair of grooves configured to hold each pair of skateboard wheels in a fixed position.
