Abstract: The present invention is directed to a self-locking non-backdrivable gear system. The gear system may comprise a primary motor input and gear box. The primary motor input is for rotation of the gearbox about the axis of a drive shaft. The gearbox may comprise an input ring gear, one or more locking gears, fixed gear, and output gear. In operation, rotation of the primary motor input causes rotation of the ring gear which causes rotation of the locking gear which causes rotation of the output gear which causes rotation of the drive shaft. However, in the absence of rotation of the ring gear, a rotational force applied to the output gear causes the gear teeth on the fixed and output gears to lock the gear in place.

Abstract: The present invention provides a transmission capable of providing a forward and a reverse drive for a model vehicle. The transmission comprises a drive gear and at least one transfer gear which is capable of engaging the drive gear. The at least one transfer gear is contained within a gear housing. An output gear is coupled to an output shaft, and the output gear is capable of engaging the at least one transfer gear. The transmission also comprises a locker ring capable of receiving the output gear and a shift lever assembly which is coupled to the locker ring. The shift lever assembly is also capable of engaging the gear housing. The invention also provides a method of changing a direction of travel of a vehicle and a system for controlling a direction of travel of a vehicle.

Abstract: The Internal Combustion Engine Efficiency Unit (“ICEEU”) is a device that improves the fuel efficiency of vehicles powered by internal combustion engines, producing low-emission vehicles. It accomplishes this by replacing a single larger engine with two smaller engines, connected together via the ICEEU to produce a single rotary output that powers the vehicle. Both engines are used together when power is needed, but one engine can be shut down when the vehicle is cruising and needs less power to simply maintain its forward momentum. The ICEEU effectively removes the second engine completely from the power train when it is unneeded, so that it does not produce any drag, and also allows the second engine to reenter the power train as needed at any RPM or torque. The ICEEU comprises an open differential and two planetary gear sets to provide the phase shifting ratio that allows for a pair of internal combustion engines to be integrated and separated smoothly throughout operation.

Abstract: A high output transmission is made for increasing speed and torque from an engine or motor. It includes a planetary drive for gradually increasing speed output, a speed reducer for increasing torque output, and a friction brake which gradually slows and stops a wheel member of the planetary drive. The planetary drive wheel member is gradually slowed and stopped so that the planetary drive input to output speed ratio is increased starting from a 1 to 1 speed ratio. As the braking force is gradually increased power output is transmitted starting with a slow speed with high torque to a fast speed with lower torque and when the braking force is decreased power output resumes to a slow speed with high torque while the engine or motor can run at a set or constant speed. A clutch means is included in the transmission by the on/off action of the brake thereby providing a clutch and continuously variable transmission or CCVT.

Abstract: The invention comprises a simple and efficient transmission for varying speed and engagement of power, comprising a planetary drive with input means driven by a prime mover's output, scheduled friction clutch means for gradually slowing and stopping rotation of an idler wheel member of the planetary drive so that as the force of the clutch is increased, power is automatically transferred from the idler wheel member to the output of the planetary drive, starting with a slow speed with high torque to a fast speed with lower torque by scheduled increments which enable rotation of the output shaft, under load resistance, without prime mover stall.

Abstract: An infinitely variable rotary drive transmission system which provides a true infinitely variable speed range that begins with zero output and accelerates smoothly and steplessly into the over-drive range, provides limitless horsepower capacity and does not require a clutch mechanism to change speeds. The infinitely variable rotary drive transmission system comprises an input shaft, hub assembly, a plurality of identical differential gear assemblies and a plurality of cam rod assemblies operatively coupled to vary the rotational output velocity of an output shaft.

Abstract: A torque enhancer for use between a driving member and a driven member includes a housing and a gear set rotatably supported within the housing. The gear set has an input member, an output member, and a reaction member. Torque is transferred between the input member and the output member when rotation of the reaction member is resisted. A braking element is disposed within the housing and operably engages the reaction member to resist the rotation of the reaction member, thereby causing torque to be transferred between the input member and the output member. A controller means connected to the brake means modulates engagement of the reaction member by the brake means to maximize output member acceleration.

Abstract: This invention relates to a power transmission device for coupling an input or driving shaft with an output or driven shaft. The power transmission device permits the output shaft to be engaged or disengaged from the input shaft. The device comprises a first side gear mechanically connected to the output shaft and a second side gear mechanically coupled to a brake which can decrease the rate of rotation of the second side gear to zero. In one embodiment, the gear ratio between the first side gear and the second side gear is greater than one. The device further comprises carried gears rotatably engageably coupled with the first and second side gears such that the carried gears rotate between and around the first and second side gears. The carried gears are carried by a gear carrier. The carried gears are mechanically connected to the gear carrier such that rotation of the input shaft on its axis causes the gear carrier to carry the carried gears around the first and second side gears.

Abstract: A mechanic drive apparatus includes a driving shaft and a hollow rotatable housing which has a rear side mounted on one end of the driving shaft. An output shaft extends into the rotatable housing and is mounted rotatably thereto. The output shaft is aligned axially with the driving shaft. A driven gear is mounted fixedly on the output shaft and is disposed inside the rotatable housing. A pair of driven transmission shafts are disposed on opposite edges of the driven gear. Each of the driven transmission shafts is provided with a worm segment that extends into the rotatable housing and that meshes with the driven gear. A pair of intermediate shafts are mounted rotatably to the rotatable housing in a direction which is transverse to the output shaft. A small bevel gear is mounted fixedly on each of the intermediate shafts. A pair of belt drive units transmit the rotating force of the intermediate shafts to the driven transmission shafts.

Abstract: A variable transmission is disclosed. An input shaft for rotational input has a first gear securably mounted at the terminal end of the input. A cross shaft is spaced apart from the terminal end of the input shaft and a second gear is securely mounted at the second end of the cross shaft with the second gear in direct mechanical communication with the first gear. A fifth gear with a hub is rotatably mounted on the input shaft. A third gear is securably mounted at the first end of the cross shaft with the third gear being in direct mechanical communication with the fifth gear. An output shaft terminates in a fourth gear with the fourth gear positioned opposite the fifth gear and in direct mechanical communication with the third gear.
