摘要:
The present invention provides a two wheel vehicle structure, including: a vehicle frame and a multi-ratio transmission system. The vehicle frame has two wheels and an input tubular member. A crank is attached at each end of the input tubular member. The multi-ratio transmission system includes: a multi-ratio transmission device, a first sprocket, a second sprocket and a chain. The multi-ratio transmission device is installed inside the input tubular member and located at a rotation center of the cranks. The second sprocket is coaxially installed on a wheel axle of a driving wheel and is provided with a ratchet wheel. When the cranks rotate, the rotation motion of the cranks are transmitted to the first sprocket through the multi-ratio transmission device, subsequently, the motion is transmitted to the second sprocket from the first sprocket through the chain, thereby propelling the driving wheel to rotate.

The second sprocket is coaxially installed on a wheel axle of a driving wheel. The chain is engaged with the first sprocket and the second sprocket. When the cranks rotate, the first sprocket also rotates in synchronization therewith. The rotational motion generated is transmitted to the multi-ratio transmission device and at the same time transmitted to the second sprocket through the chain, thereby propelling the driving wheel to rotate.

A multi-ratio transmission system with parallel vertical and coaxial planet gears is provided, including: multiple planet gear sub-systems, a coupling assembly, a setting element, a setting element controller, an annular gear, a cylindrical casing, a sprocket and a central axle. The planet gear sub-systems are disposed coaxially in series along a first axis. Each of the planet gear sub-system includes a sun gear and at least one planet gear. The coupling assembly transmits the rotation between every two adjacent planet gear sub-systems. The setting element optionally engages with the sun gear. The annular gear is engaged to the planet gear and is installed onto a one-way clutch. The cylindrical casing encloses the planet gear sub-systems. The sprocket is installed onto the one-way clutch for connecting an external transmission system. The central axle enables the hollowed tube of the setting element controller to rotate around the central axle.

An optical precision mold machining device is mountable on a chuck of an ultraprecision machining apparatus to perform an aspherical molding process by a cutting tool, and includes a fixture gripped by jaws of the chuck and having positioning holes in a matrix arrangement, a plurality of fasteners extending through the corresponding positioning holes, and a mold including a retained surface with locking holes for insertion of the fasteners, and a mold surface portion having a sprue, a runner and multiple mold bases. Each mold base has sub-runners in communication with the runner. An injection direction of the sprue is parallel to an initial running direction of the runner. The mold is moved with the fixture relative to the cutting tool to a predetermined machining position where each mold base is machined to form therein a cavity with an aspherical cross-section.
