摘要:
The present invention relates to controlling a speed of each wheel required for riding in a curved section or an unexpected situation for a motorcycle which is realized in "Korean Patent Number 10-0873537 titled a two-wheel moving body and a motorcycle having the same" and to which an electric motor is applied, and for a motorcycle or a transport means which is motor-driven, wherein two or more independent drive motors are applied to a front wheel and/or a rear wheel thereof. When a motor-driven transport means having three or more wheels runs in a curved section, since a rotational speed of a wheel disposed on an outer side from a center of a curve radius must be higher than a rotational speed of a wheel disposed on an inner side, riding stability can be seriously affected if the motors are not individually controlled to change the speeds. Accordingly, precise control for each motor is required. The present invention resolves the problem by using a physical phenomenon which occurs in the transport means when riding in a curved section and unique properties of a BLDC motor without using an additional controller. The motorcycle and the transport means mentioned above use the motor of an independent drive form for each wheel to consume less energy than when maneuvering the transport means with one motor and improve maneuverability and energy efficiency.

Die vorliegende Erfindung betrifft insbesondere eine Vorderradbaugruppe zum Antreiben eines Vorderrads eines Motorrads (M) mit Allradantrieb, mit - einer anzutreibenden Nabe (N), an der das Vorderrad angeordnet wird, - einer drehbaren Antriebswelle (AW) mit einem Antriebselement (AK), das zur Kopplung mit einem von einem Motor des Motorrades (M) angetriebenen Kraftübertragungselement ausgebildet und vorgesehen ist, um ein Drehmoment an die Antriebswelle (AW) zu übertragen, - einem Wellengelenk (1) zur Übertragung eines Drehmoments von der Antriebswelle (AW) an die Nabe (N). Erfindungsgemäß ist das Wellengelenk (1) zentral an der Nabe (N) angeordnet und als homokinetisches Wellengelenk ausgebildet, das die Antriebswelle (AW) und die Nabe (N) drehmomentübertragend und derart gelenkig miteinander verbindet, dass eine Winkelstellung der rotierenden Nabe (N) relativ zu der drehenden und die Nabe (N) antreibenden Antriebswelle (AW) über einen Lenker (LS) des Motorrads (M) veränderbar ist.
摘要:
The present invention is a two-wheel drive motorcycle. The drive train that supplies power to the front wheel is modified to include a series of rigid shafts or other internalized drive systems. The front wheel drive consists of components located on the axis of steering within the head tube and positioned symmetrically in a counterbalancing fashion within the front fork in order to counteract the torque reactions from the rotating fron wheel drive while providing a full range of steering. The front wheel drive lengthens and shortens in parallel with the shock-absorbing front fork. An engagement clutch, a one-way hub, and torque limiting clutch for the front wheel drive are also disclosed.

An alternating drive for wheeled vehicles comprises two opposite pedals which can move on a circular path about a pedal shaft secured on the cycle frame. The alternating drive is characterized in that it is equipped with two cranks (26, 27; 26a, 27a; 26b, 27b) which can be moved within a predetermined oscillating angle range about an auxiliary shaft (25) secured to the frame (10). Between the cranks (26, 27; 26a, 27a; 26b; 27b) and the pedals (21) is a driver connection which transforms the circular motion into an alternating oscillating motion with phases mutually offset by a half oscillation period. Disposed on each side of the axle (50) of the driven wheel (12) is a free-wheel mechanism (56, 57). The free-wheel mechanisms (56, 57) lock in opposite directions and are connected to the individual cranks (26, 27; 26a, 27a; 26b, 27b) by mutually independent traction elements (29; 82, 83).
摘要:
A two-wheel drive cycle (10) comprises a frame (11), a front fork assembly monted on the frame through a pivotal connection to steer the cycle, a front wheel (22) rotating on the fork assembly (20) about a first axis (40), and a rear wheel (24) rotating on the frame about a second axis (36). A front sprocket (4) is mounted on the front wheel and centered on the first axis to drive the front wheel, while a rear sprocket (42) is mounted on the rear wheel, is centered on the second axis and driven through the pedals or motor. A chain (43) is meshed with both the front and rear sprockets and guided between these front and rear sprockets through a plurality of gears and pulleys (44-48), including a set of gear and pulley engaging the chain and rotatively mounted on the frame close to the pivotal connection. A spring mechanism lengthens and shortens the chain loop as the front fork assembly is turned. In operation, the front wheel is driven through the pedals or motor, the rear sprocket, the chain meshed with both the front and rear sprockets, and the front sprocket.
摘要:
La bicyclette à entraînement sur les deux roues utilise un axe flexible allongé (50) ou câble servant à transmettre le mouvement rotatif ou le couple à la roue avant. Dans le mode de réalisation préféré de l'invention, une couronne dentée arrière (34) est montée sur la roue arrière pour actionner un pignon conique arrière (36). L'une des extrémités de l'axe flexible allongé (50) est reliée au pignon conique arrière (36) qui lui transmet un mouvement d'entraînement; l'autre extrémité dudit axe (50) est reliée à un pignon conique avant (55) venant en prise avec une couronne dentée avant (56) solidaire de la roue avant et actionnant ladite couronne. Un ensemble servant au déplacement en roue libre (60) se situe entre la couronne dentée avant (56) et le moyeu (100) de la roue avant pour faciliter la négociation de virages. Dans un autre mode de réalisation, l'ensemble de déplacement en roue libre (60) fait partie du pignon conique avant (55). L'invention s'applique à des bicyclettes à une ou plusieurs vitesses.
