摘要:
The power transmission system for a vehicle includes a side flex chain assembly that transmits rotational drive from a power transfer assembly to at least one direction wheel, resulting in propulsion of the vehicle. The orientation of the side flex chain in relation to the axis of the crank sprocket and the side flex chain sprocket and the convex inner face of the bushings of the side flex chain allow the side flex chain to twist when the at least one directional wheel turns left or the right without disengaging from the crank sprocket or the side flex chain sprocket. The power transmission system is designed to be used with a steering system that allows the power transfer assembly to remain substantially in the sagittal plane when steering.

A toy vehicle for children, comprising a vehicle frame, a steering rod, and a front wheel component provided at the bottom of the steering rod. The vehicle frame comprises a main vehicle frame provided with a seat mechanism, a left side frame with a left rear wheel assembly, and a right frame with a right rear wheel assembly. The left side frame and the right side frame respectively are rotatably connected to the rear of the main vehicle frame. The vehicle frame is further provided with a driving mechanism used for driving the left side frame and the right side frame to rotate respectively relative to the main vehicle frame so as to allow the left rear wheel assembly and the right rear wheel assembly to approach or to move away from each other, and an operating mechanism used for driving the movement of the driving mechanism.

A toy vehicle for children, comprising a vehicle frame (1), a steering rod (4) extending in the vertical direction, and a front wheel component (2) provided at the bottom of the steering rod (4). The vehicle frame (1) comprises a main vehicle frame (1) provided with a seat mechanism (7), a left frame (12) provided at the rear with a left rear wheel component (31), and a right frame (13) provided at the rear with a right rear wheel component (32). The left frame (12) and the right frame (13) respectively are rotatably connected to the rear part of the main vehicle frame (1). The left rear wheel component (31) and the right rear wheel component (32) are omnidirectional wheels. Also provided on the vehicle frame (1) are a driving mechanism used for driving the left frame (12) and the right frame (13) to rotate respectively relative to the main vehicle frame (1) so as to allow the left rear wheel component (31) and the right rear wheel component (32) to approach each other or to move away from each other, and an operating mechanism used for driving the movement of the driving mechanism.

A sliding method on ice-surface aims at solve the problems of power output and poor durability and the difficulty in large-scale promotion. An ice-surface sliding tool includes a seat board, a U-shaped rod, sliding plates, H-shaped connecting frames, a pushing device, a hand-operated chain wheel and a reversing gear. One end of the upper end surface of the seat board is provided with a backrest. The U-shaped rod is provided on the side wall of the other end of the seat board. The lower end of the seat board is symmetrically provided with two sliding plates in parallel to each other. The sliding plates are connected with the lower end surface of the seat board through the H-shaped connecting frames. The pushing device is rotationally provided between the two H-shaped connecting frames. The hand-operated chain wheel is on the upper end of the U-shaped rod through a support bar.

A two wheeled vehicle is propelled by the feet of a rider and hand-grasped poles when pushing against the ground. A forward wheel on a forward member and a rear wheel on a rearward member align along a longitudinal axis. The forward member rotates about a vertical steering axis. A saddle supports the rider. A torso brace allows the rider to balance and steer the device.

A human-powered vehicle may include a frame and a drive member pivotally coupled to the frame. Pivotal reciprocal motion of the drive member in either direction may generate rotational motion to the wheels of the human-powered vehicle. The seat of the human-powered vehicle may be positioned such that an axis about which the drive member pivots is located below, or closer to the ground surface, than the seat.

A manually-powered vehicle propelled by muscular force, whose user maintains a standing position, and whose drive is hand-held. The vehicle according to the invention includes two drive wheels, with independent mechanisms installed inside them, which transform the swinging motion of the levers into unidirectional gyration of the drive wheels axis thus driving the vehicle forward, at least one neutral wheel mounted in a way allowing rotation around the vertical axis, and where a low-slung platform is attached directly to the casing of the mechanisms.

A human-powered-system utilizing an arm lever assembly and/or a pedal assembly to be adapted to or incorporated into other mechanisms including, but not limited to, wheelchairs and vehicles. The arm lever assembly includes an arm lever that is reciprocated to provide power and rotated left or right to provide steering control. Both assemblies are operatively connected to a converter, utilizing gears and one-way clutches that receives the reciprocal movements of the arm lever and converts them into a unidirectional output, to be utilized in combination or independently. The arm lever is further telescoping and when utilizing a slide mechanism operatively connected to the converter representing a first class lever offers a range of various leverages by correspondingly changing the length of the force and load end when extended and retracted.
