摘要:
A motorcycle (100) provided with a frame (102), two front steering wheels (12, 12), a right and a left steering pipe rotatably connected to the frame (102) and rigidly connected to two supporting assemblies (16, 16), one for each front steering wheel (12, 12) and a steering group consisting of two pairs of transversal arms - upper front (66), lower front (68), upper rear (70) and lower rear (72) arranged inverted at the opposite sides of a central steering pipe (14') and laterally connected through two lateral posts (74, 76) wherein on each of the supporting assemblies (16, 16) the fixed portions of two telescopic elements (22, 24) are constrained and each pair of telescopic elements (22, 24) is cantilever-mounted as regards the relative steering wheel (12).
摘要:
A vehicle control device which can provide compatibility between a high grip performance and fuel efficiency is provided. When a camber angle of a wheel 2 is adjusted to a negative camber, ground contact pressure in a first tread 21 is increased and ground contact pressure in a second tread 22 is decreased. Accordingly, the high grip performance is provided. On the other hand, when the camber angle of the wheel 2 is adjusted to a positive camber, the ground contact pressure in the first tread 21 is decreased and the ground contact pressure in the second tread 22 is increased. Accordingly, a rolling resistance becomes low, and fuel saving is achieved. In this manner, by adjusting the camber angle of the wheel 2, the compatibility can be provided between conflicting performances of the high grip performance and the fuel saving.

摘要:
Provided is a vehicle which, when a pair of left and right wheels are displaced with respect to the vehicle body due to the difference in drive force between the wheels, the two wheels are reliably displaced vertically in opposite directions such that neither wheel is disproportionately displaced and such that both wheels are steered during said displacement of both wheels vertically in opposite directions. The pair of left and right front wheels (3) are rotatably supported by a front wheel support member (29). An electric motor (25) applies drive torque to the front wheels (3) individually. A vehicle body frame (7) supports the front wheel support member (29) to allow rotation about a forwardly inclined steering axis (Lf). By allowing rotation of the front wheel support member (29) about the steering axis (Lf), the front wheels (3) are displaced relatively to one another vertically in opposite directions with respect to the vehicle body frame (7) and the front wheels (3) are steered. The front wheel support members (29) rotate due to the difference in torque applied to the front wheels (3) by the electric motor (25).

摘要:
Eine Radaufhängung (10) für ein Fahrzeug mit einem tragenden Fahrzeugelement (14) umfasst mindestens ein Paar von Einarmschwingen (12A,12B). Jeder Einarmschwinge (12A,12B) ist ein Hydraulikzylinder (18A,18B) zugeordnet, welcher an der Einarmschwinge (12A, 12B) und/oder an dem tragenden Fahrzeugelement (14) angelenkt ist. Jeder Hydraulikzylinder (18A,18B) ist durch einen beweglichen Kolben (25A, 25B) fluiddicht in zwei Kammern unterteilt. Eine erste Kammer (26A-1,26B-1) des Hydraulikzylinders (18A,18B) ist durch eine aktive Funktion und eine zweite Kammer (26A-2,26B-2) desselben Hydraulikzylinders (18A,18B) ist durch eine passive Funktion gekennzeichnet. Die aktive Kammer (26A-1,26B-1) ist flüssigkeitsgefüllt. Die aktiven Kammern (26A-1,26B-1) eines Einarmschwingen-Paars (12A,12B) kommunizieren über eine Flüssigkeitsleitung (28) in einem geschlossenen System miteinander. Die passive Kammer (26A-2,26B-2) ist fluidgefüllt, wobei das Fluid in der passiven Kammer (26A-2,26B-2) eine Kraft auf die Rückseite des Kolbens (25A,25B) ausübt, die im Wesentlichen der durch den Druck der Umgebungsluft ausgeübten Kraft entspricht und dadurch Positionen des Kolbens (25A,25B) unwesentlich beeinflusst.

摘要:
A riding lawn care vehicle may include a frame, a steering assembly, and an axle mount. The axle mount may include a first sleeve and a second sleeve disposed at opposite ends of the axle mount. The first and second sleeves may receive top portions of a first axle rod and a second axle rod. The first axle rod and the second axle rod each include a top portion and a bottom portion bent with respect to the top portion. The bottom portion may be received by the rear wheels. The first and second sleeves may be disposed in a fixed position relative to the axle mount and an orientation of the first and second sleeves may be provided such that the bottom portion of each of the first and second axle rods is substantially parallel to a driving surface in response to the steering wheel being oriented in a neutral position.
