摘要： A frame of a vehicle includes a front fork unit pivotably connected to a head tube of a vehicle body mechanism, a crank axle disposed on the front fork unit for two front-wheel cranks to be pivoted thereon. Two front wheels are pivotably disposed on the cranks, respectively. A front-wheel counteracting mechanism is pivotably connected between each of the cranks and the front fork unit to transmit an impact force to the cranks so as to cause opposite upward and downward movements of the front wheels to thereby keep the front wheels in contact with the ground and to render movement of the vehicle steady and safe.

摘要： A self-balancing vehicle frame is mounted with two angle sensors and two wheels that are electrically and respectively coupled to the angle sensors, and includes a front frame assembly that includes two front frame units and a first connecting unit. The front frame units cooperatively define a connecting space therebetween. Each of the front frame units is mounted with a respective one of the wheels and a respective one of the angle sensors, and is operable to tilt the corresponding one of the angle sensors. The first connecting unit is located in the connecting space, and interconnects the front frame units such that the front frame units are rotatable relative to each other.

摘要： A servo system includes a tubular drive shaft journalled in a housing. A screw is engaged threadably with a nut which is fixed in the drive shaft. A driven body is secured to an end of the screw so that the screw can effect a rectilinear movement with the driven body but cannot rotate. A motor can rotate the drive shaft in an infinite angle through a gearing so that the drive shaft can move in a first direction continuously. Then, an end of a fork is rotated by an abuttment element which is sleeved on the drive shaft. At this time, the other end of the fork activates a hydromechanical servo, and hence a hydraulic driving unit, to move the drive body in a second direction which is equal and a opposite the first direction. After which, the drive shaft is moved back to the original position by the driven body. The driven body is therefore moved a predetermined distance. In this way, the driven body can be moved, accelerated, decelerated and stationary in accordance with the input of the specific numerical control signal.

摘要： A self-balancing vehicle frame includes two side frame units and a bearing unit interconnecting the side frame units such that each of the side frame units can tilt independently against the other of the side frame units. Each of side frames is mounted with a wheel, a driver, and a self-balancing electric system integrated with a pedal and handle. Through operation of hands and feet, each of the side frame units is operable to tilt the corresponding components forwardly and rearwardly. As such, a user can operate the vehicle using hands and/or feet to control travelling and turning of the vehicle.

摘要： An assistance system includes a resistance detecting unit obtaining a resistance factor, a database storing starting torque values and operating torque values, a torque calculation unit including a controller, and a torque-control handlebar grip operated to trigger an assigned gain and to tune the same to be provided to the torque calculation unit. When switched to an aided mode, the controller calculates a compensated torque value based on one of the starting/operating torque values and the resistance factor, calculates an output torque value by a product of the compensated torque value, the assist ratio and the assigned gain, and controls a torque motor to drive rotation of a driving wheel based on the output torque value.

摘要： A balancing transporter is provided to mitigate occurrence of undesired sudden turning and falling of a user by virtue of various mechanisms that control the source/cause of mistakes and implement post-mistake remedies. Two adjusting members are operated by the user for turning control in a manner that interference between operations on the adjusting members and on handles is prevented. Maximum allowance of difference between wheel speeds is introduced to prevent sudden turns due to inappropriate operation. A rotational interlock unit mechanically enables the adjusting members to rotate in opposite directions to prevent sudden turns. Shock absorption and balance compensation mechanisms are introduced to keep the balancing transporter from tilting.

摘要： A front fork assembly includes a shock absorbing assembly and an anti-revolving guiding member arranged in a front-rear direction and extending in an up-down direction to interconnect a suspending bracket and the connecting bridge, left and right connecting levers interconnecting a swing arm assembly and a crank pivoting shaft, and left and right cranks for mounting with two front wheels of a tilting vehicle. Occurrence of speed wobble of the front fork assembly is prevented to render driving of electric bicycles, scooters and motorcycles equipped with the front fork assembly better and safer, to shorten the braking distance of vehicles, to prevent spinning of vehicles during braking, to prevent side slip during turning, to provide more comfortable feeling of shock absorption of vehicles, and to render the driving stable when passing over obstacles.

摘要： A method for manufacturing a rolled retraction cord is provided. The method comprises the steps of: (A) preparing the sheet, the sheet comprising a first side edge and a second side edge opposite to each other; (B) placing the sheet on a first surface of a first forming member; (C) contacting the first side edge of the sheet with a second surface of a second forming member, the first side edge of the sheet sandwiched between the first surface of the first forming member and the second surface of the second forming member; and (D) applying a force via the first surface or the second surface to the sheet, and rolling the sheet from the first side edge to the second side edge to obtain the retraction cord. With this method, a rolled retraction cord with a smooth surface and enhanced ductility is capable of being provided.

摘要： A frame mechanism for a vehicle with at least three wheels includes wheel frame assemblies to support a vehicle frame assembly. By a shock absorbing assembly, a swing arm, two synchronizing levers and two linking shafts, when any kind of loading carried and external forces are applied to the vehicle, the wheels can constantly remain on the ground surface with the same traction so as to minimize the risk of yaw, drift and unbalance upon a turn or braking of the vehicle. Also, a variety of uneven movements of the wheels can be balanced and converted into a movement of the vehicle frame assembly in an up-and-down direction. In case of the wheels running off the ground, the wheels can be kept in a proper position for retouching down with safety and comfort.
