摘要： A straddle type vehicle comprises a steering mechanism configured to steer a front wheel a steering damper device capable of variably generating a damping force working on a rotating action of the steering mechanism; and a control unit configured to control the damping force of the steering damper device to increase, when the front wheel of the straddle type vehicle in a wheelie state lands on a ground. The control unit controls the damping force to increase, after the front wheel lands on the ground and an oscillation occurs in the steering mechanism.

摘要： A bicycle comprising a frame; a handlebar assembly attached to an upper steering tube of the frame in such a way that at least the relative rotation between the two with respect to an upper axis is allowed, but the relative displacements between both in the directions perpendicular to the upper axis are restricted; a fork attached to a lower steering tube of the frame so that it has the same degrees of freedom relative to the lower axis between the fork and the lower steering tube as the degrees of freedom relative to the upper axis between the handlebar assembly and the upper steering tube; and a means for rotation transmission for transmitting at least partially a rotation of the handlebar assembly with respect to the upper tube into a rotation of the fork with respect to the lower steering tube.

摘要： A tricycle may be operable between a first mode of operation steerable by a tricycle rider, and a second mode of operation steerable by an individual pushing the tricycle. In both such first and second modes, the frame of the tricycle is configured to rotatably support the rear wheels and configured to support the head tube at a distance from the rear wheels such that a distance between the head tube and rear wheels need not necessarily be changed even when the front wheel axis location is changed from one mode to another.

摘要： A motorcycle has a front part and a rear part, the front part including handlebars and a handlebar stem with which there is associated an electronic damper controlled by a control unit controlling the action of the damper on the handlebars, provision being made for a device detecting the angle of rotation of the handlebars and the velocity of rotation of the handlebar stem within a handlebar head of the frame. The control unit includes a first block which receives data on the velocity of rotation of the handlebar stem and which on the basis of such velocity determines the presence of oscillating or weave movement of the motorcycle or a wobble movement of the handlebars, the first block of the control unit being connected to a second block and a third block of such unit which alternatively generate a control signal intended to damp the handlebar stem on the basis of the determination made by the first block so that any weave and/or wobble movement is cancelled out.

摘要： A shock-absorbent structure of an electric carrier is assembled with a steering system. The steering system includes a steering axis and two wheels linked with the steering axis. The shock-absorbent structure of an electric carrier includes a steering assembly and a wheel axle assembly. The steering assembly includes a bushing, a steering connecting portion connected to the bushing, and an accommodating space. The wheel axle assembly includes a body, two axle connecting members respectively disposed at two ends of the body, a body opening penetrating the body, an elastic body disposed between the body and the bushing, and a pressing member passing the body opening. The pressing member abuts at one end of the body corresponding to the bushing when the elastic body is in a diastolic state, and moves away from the bushing when the elastic body is in a compressed state.

摘要： A handlebar fixing structure enabling a handlebar to be attached to a high position to provide high vibration absorbency. The handlebar fixing structure includes a handlebar, a handlebar post supported above a steering system, and a handlebar clamper for fixing the handlebar to the handlebar post. The handlebar clamper includes a first damper member and a second damper member disposed so as to sandwich a cylindrical portion of the handlebar post and the handlebar from a direction orthogonal to the vehicle widthwise direction. An elastic member is interposed between the first clamper member and the handlebar post and between the second damper member and the handlebar post. The first damper member and the second clamper member are coupled with each other by a bolt and include abutting faces for abutting with each other so as to receive an axial force of the bolt.

摘要： The invention is a foot-propelled wheeled hobby and/or sport device which has a central wheel (1), a frame (4) including side plates (20) connected to each other and located on both sides of the central wheel (1) at a distance from it and foot plates (5) on the lower part of the side plates (20) protruding outwards from them, located below the wheel axle (6) which has a wheel hub (2) and, furthermore, a satellite wheel (7), connected to the frame (4), with a diameter smaller than the central wheel (1). The essence of the invention is that from the point of view of the main propelling direction of the device the satellite wheel (7) is located in front of the central wheel (1). The frame (4) has front and rear frame members (21a, 21b) stiffening the side plates (20), running along their side edges opposite each other. Stable stiffening members are connected at the end parts of the foot plates (5) to the lower ends of the frame members (21a, 21b). The height above the ground of the running surface of the satellite wheel (7) is selected with consideration to the flexibility of the flexibly deformable tyre of the central wheel (1) so that when the wheel tyre (23) is depressed on the effect of the weight of an averagely built person using the device the satellite wheel (7) comes into contact with the ground, so ensuring that the foot plates (5) are horizontal or essentially horizontal.
