Embodiment Construction

[0034] Please refer to figure 1 , figure 1 A perspective view showing a locomotive turning left according to an embodiment of the present invention. Locomotive 100 has front wheels 102 and 104 suspended by axle 110, which is fixed to biaxial hub 202 (see figure 2 ), a steering arm 302 (see image 3 ) is connected to the frame 116 by a pair of wishbone (wishbone) 118, and another rear wheel 108. Note that the front wheels 102 and 104 are all planes, and the contact area between the tires and the ground is increased, so it is more stable and safe when braking and turning.

[0035] Please refer to figure 2 , figure 2 Shows front, side, and cutaway views of the front wheel steering system. figure 2 (A) is the front view of the front wheel steering system. Both front wheels 102 and 104 have tires with flat ground contact surfaces supported by the axle 110 of the biaxial hub 202. Below the axle 110 of the biaxial hub 202, there is a tilting axis 204 which is longitudinal ...

Abstract

The invention discloses a front wheel tilt-preventing front suspension and steering system for bicycles and motorcycles, wherein a frame is provided with two front wheels and a back wheel, the front wheels are provided with planar ground surfaces, a double-shaft hub is provided with a wheel shaft for supporting the two front wheels, a tilting bearing is arranged under the wheel shaft, a steering arm is provided with a tilting shaft, when the steering arm tilts, the tilting shaft can rotate in a titling shaft core, and the steering arm is connected to the frame through a pair of wishbones. During a turn, the steering arm, the frame and the back wheel tilts towards the turning side so as to keep the gravity center at the turning side to balance the centrifugal force, but the front wheels and the double-shaft hub do not tilt, so the turning is comparatively smooth and safe.

Description

technical field [0001] The invention relates to a suspension and steering system, in particular to a front suspension and steering system used for bicycles and locomotives to prevent the front wheels from tilting. Background technique [0002] Tricycles or locomotives have been provided in various single-wheel steer and two-wheel steer configurations. However, it still cannot make the product ride safely when turning or emergency braking. In fact, perhaps a common problem with tricycles or motorcycles is the lack of stability of the vehicle when turning left or right. The front wheel usually tilts so that the surface of the tire contacts the ground at the edge, thereby reducing the friction between the tire and the ground and causing it to slip outwards. [0003] US Patent No. 4,375,293 to solbes discloses a suspension and steering system in which all tires are tilted during a turn so that the friction between the tires and the ground is limited and the result is outward s...
