Cycle Transmission Exhibiting Low Steering Interference Effects

Номер: US20160039493A1
Автор: Payne Thomas Andrew
Принадлежит:

A novel transmission for cycles that significantly reduces torque interference with steering operations is provided. Such a transmission allows for improved recumbent cycling capabilities. The inventive device thus includes a combination of a fixed transmission assembly that reduces torque levels and a movable transmission assembly that multiplies torque levels, allowing for the avoidance of high torque effects through the vehicle's steering axis. As such, the capability of the overall cycle device to steer properly and to a rather wide angle from center while implementing such a torque transfer protocol allows for a unique recumbent cycle configuration. Such a device, then, may be utilized for a human-powered cycle vehicle or one that further includes an electrical component to allow for automated drive capabilities through a rear wheel or wheels, as well. The method of implementation of such a transmission within a variety of cycle devices is also encompassed within this invention. 1. A combination manual/electrical vehicle comprising a frame , a vehicle transmission , a manual pedal assembly , a plurality of wheels , a steering component exhibiting a steering axis , and an electrical power generation component , wherein said vehicle transmission comprises a fixed transmission assembly component that exhibits torque reduction and a subsequent movable transmission assembly component that exhibits torque multiplication , wherein said fixed transmission assembly component is attached to said frame and said movable transmission assembly component is rotatable about said steering axis , wherein said vehicle transmission comprises both direct and overdrive capacities , wherein said fixed and movable components comprise a single power transmission path , and wherein said electrical power generation component provides for the automated movement of at least one of said wheels on demand.2.

Автор: Yuuichi Yoneda
Принадлежит: Yamaha Motor Co Ltd

A drive unit for use in an electric straddled vehicle provides high motor output while the size of the drive unit is kept from increasing. The drive unit includes a motor, a first gear, a rotation shaft, a second gear, and bearings. The motor includes a rotor shaft. The first gear is provided on the rotor shaft to rotate at a same speed as the rotor shaft. The rotation shaft is parallel or substantially parallel to the rotor shaft. The second gear is provided on the rotation shaft and meshes with the first gear. The bearings support the rotation shaft in a rotatable manner. The bearings at least partially overlap the motor when viewed in an axial direction of the rotation shaft.

Smart gearing system for bicycle

Номер: US09976630B2
Автор: Kim Leung Luk
Принадлежит: Individual

A bicycle gearing system includes input and output shafts, two planetary gear systems, and a clutch mechanism. The clutch mechanism includes three clutch presser plates for frictional engagement with two clutch disks and a clutch base. A motor rotates a camshaft formed with cams selectively engageable with cam followers for driving the clutch presser plates to rotate. Steels balls are provided within cavities formed between the clutch presser plates and a clutch housing to convert rotation of clutch presser plates to linear force for frictional engagement with the two clutch disks and the clutch base. Different angles of rotation of the camshaft produce different clutch and gear combinations and different gear ratios.

Cycle transmission exhibiting low steering interference effects

Номер: US09669895B2
Автор: Thomas Andrew Payne
Принадлежит: Individual

A novel transmission for cycles that significantly reduces torque interference with steering operations is provided. Such a transmission allows for improved recumbent cycling capabilities. The inventive device thus includes a combination of a fixed transmission assembly that reduces torque levels and a movable transmission assembly that multiplies torque levels, allowing for the avoidance of high torque effects through the vehicle's steering axis. As such, the capability of the overall cycle device to steer properly and to a rather wide angle from center while implementing such a torque transfer protocol allows for a unique recumbent cycle configuration. Such a device, then, may be utilized for a human-powered cycle vehicle or one that further includes an electrical component to allow for automated drive capabilities through a rear wheel or wheels, as well. The method of implementation of such a transmission within a variety of cycle devices is also encompassed within this invention.
