Front and a rear truck are mounted to the bottom of the deck. At least one of the first and front and rear trunks are 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 mounted on a rear end of the deck. Upper and lower control arms share a single shaft.

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. Skateboards 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 removable skateboard brake apparatus for easily adding and removing brakes to a skateboard includes a clip base having a base underside and a base top side. A clip top has a top underside and a top top side. The top underside is pivotably coupled to the base top side. A spring is coupled to the clip base and the clip top to bias the clip top towards the clip base. The clip base and the clip top are attached to a deck of a skateboard. A brake housing has a housing top side coupled to the base underside, a housing bottom side, a housing inner side, a housing outer side, and a pair of housing lateral sides. A brake pad is coupled to the brake housing. The brake pad is coupled to the housing bottom side to contact a wheel perimeter of a wheel of the skateboard.

A caster board can include a front platform, a rear platform, and at least two neck sections extending between the front platform and the rear platform. The neck sections can serve as a torsion element allowing twisting of the front platform relative to the rear platform. An aperture between the neck sections can be configured to receive an insert. The insert can alter a structural characteristic of the caster board, such as the torsional stiffness of the caster board.

The invention comprises a truck and riding devices with a lean steering spatial mechanism comprised of rigid bodies and a single compliant body connected by joints forming a closed kinematic chain wherein the compliant body provides compression, tension, and torsional return spring forces for multi-axial functionality within the constraints of the lean steering spatial mechanism, allowing for the combined functionality of deep deck lean, improved lean steering control over a wider range of speed, improved speed stability, and full load bearing suspension. The invention has additional degrees of freedom and additional primary motions of floating and suspension.

Disclosed is a rotation mechanism (4) for an electric balance car. The rotation mechanism connects a left car body and a right car body of the electric balance car, and comprises a rotary shaft (40), a sleeve ring (41) and a bearing (42), wherein the sleeve ring (41) is fixedly connected to one side of the rotary shaft (40), the bearing (42) is sheathed on the other side of the rotary shaft (40), and a limiting part (411) is protruded outwardly at a position of an outer edge of the sleeve ring (41). Also disclosed is an electric balance car, comprising the rotation mechanism (4). The rotation mechanism of the electric balance car has a firm and reliable structure, operates smoothly, is convenient to install, and is durable.

An electrical balance car comprises pedals. Each pedal has a convex part located on the edge, and a concave part located in the middle and used to restore the pedal after the pedal descends under the effect of acting force. The electrical balance car can be controlled steadily and is ingenious in structure, easy to assemble and durable.

An electric weight sensing skateboard using one or more strain gauge systems to detect rider-induced strain on one or both trucks, an inertial sensor to detect accelerations and balance position, and wheel speed sensors. Throttle is controlled by rider position, for example, lean forward to increase speed, lean back to slow down. Several drive methods include a driver position detection velocity setpoint control, torque setpoint control, and direct velocity/torque control. A throttle remote is note required. Rider weight activates the motors.

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.

A steering axle unit (24) for chassis or skateboards, comprising a bearing block (1) and a steering axle body (98), wherein the bearing block (1) has a fastening plane (11) for fastening to a chassis or skateboard, particularly skateboard deck (52), wherein, in the assembled state, the fastening plane (11) is arranged on the chassis or skateboard particularly so as to be parallel to the designated direction of travel (25) of the chassis or skateboard, and wherein the bearing block (1) comprises a vertical axis CD (22) about which the steering axle unit (98) is arranged so as to rotate relative to the bearing block (1), an axle (8) that projects normally from the vertical median longitudinal plane of the bearing block (1) in the straight-ahead position being arranged on the steering axle body (98), wherein the vertical axis CD (22) is arranged on the median longitudinal plane of the bearing block (1) at an angle W1 (19) of less than 90° relative to the fastening plane (11) in the direction of the steering axle body (98), wherein the axle (8) is arranged at a normal distance (20) to the vertical axis CD (22), and wherein the axle (8) is arranged in front of the vertical axis CD (22) in the designated direction of travel (25) of the chassis or skateboard.
