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.

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 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 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.
摘要翻译： 伺服系统包括轴颈安装在壳体中的管状驱动轴。 螺钉与固定在驱动轴中的螺母螺纹接合。 被驱动体被固定到螺钉的端部，使得螺钉可以与被驱动体发生直线运动，但不能旋转。 电动机可以通过齿轮将驱动轴以无限大的角度旋转，使得驱动轴可以在第一方向上连续地移动。 然后，叉子的一端由套在驱动轴上的邻接元件旋转。 此时，叉的另一端激活液压机械伺服机构，并因此启动液压驱动单元，以沿与第一方向相同和相反的第二方向移动驱动体。 此后，驱动轴通过被驱动体移回原来的位置。 因此，被驱动体移动预定距离。 以这种方式，根据特定数字控制信号的输入，被驱动体可以被移动，加速，减速和静止。

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.

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 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 processing machine includes a slide seat, a spindle head seat and a workpiece exchanger. A threaded guide rod is journalled on a machine bed, and is rotatable to move the slide seat on the machine bed along a first direction. The spindle head seat is mounted movably on the slide seat, and is movable reciprocally along a second direction perpendicular to the first direction. The workpiece exchanger includes an exchanger body mounted rotatably on the machine bed at a position adjacent to the spindle head seat, and two worktables mounted respectively and movably on opposite side surfaces of the exchanger body. The workpiece body is rotatable about a third direction, which is perpendicular to the second direction, by 180 degrees to align a selected one of the worktables with the spindle head seat.
