Abstract:
A three wheeled vehicle (502) is disclosed having a vehicle frame (504) with a frame sidewall providing a substantially flat surface, with recesses in the flat surface. Alignment arms have inner ends and outer ends, where the inner ends are mounted to the frame sidewall, and the outer ends mount a wheel hub. The inner ends have couplings with pivotal portions and fixed portions, the pivotal portions being at least partially positioned within the recesses, and the fixed portions being attached to the substantially flat surface.
Abstract:
A self propelled conveyance is disclosed having an extendable frame. A floor pan is attached to the inner perimeter of the extendable frame and a driver's seat is disposed on a front to back center line of the floor pan. A pair of front wheels are attached to the extendable frame. The front wheels extend beyond the outer perimeter of the frame. A rear wheel assembly is one or two individual wheels separated by a short distance. Like the front wheels, the rear wheel assemble extends beyond the outer perimeter of the frame. Passenger seats are disposed behind the driver seat and each of the passenger seats are offset from the center line of the conveyance. Because the wheels extend beyond the perimeter of the frame, they act as active collision shock absorbers in collisions.
Abstract:
A children's ride-on vehicle is provided with a chassis (12) formed at least in part of molded plastic, a seat (14) mounted to the chassis (12) and configured to accommodate a driver, and first and second driven wheels (16, 18) mounted to the chassis (12) on opposite sides of the seat (14). A motive power source for the wheels (16, 18), including a battery (38) and two electric motors (112, 114) is mounted to the chassis (12) and is operable to drive each wheel (16, 18) selectively in a forward direction or a reverse direction under control of a foot-pedal (74), power/braking switch and two armrest-mounted joysticks (20, 22).
Abstract:
Three-wheeler having two front wheels acting as directional wheels, and one rear wheel acting as the driving wheel, endowed with a considerably high transversal and longitudinal stability thanks to the particular ratio between its values of wheel base and track, to the arrangement of its seats, and to its rear suspension, the vehicle being equipped with reverse gear installed on one of its front wheels.
Abstract:
Three or four wheeled vehicle which leans into corners so as to remain stable even when the vehicle has a narrow track. The steering mechanism is such that leaning of the vehicle to either respective side of the vertical causes the front steering wheels (10) to turn in the same steering direction, e.g. a lean to the left causes an anticlockwise, when viewed from above, turning of the front wheels (10). The front wheels (10) can be supported on a parallelogram linkage system (17, 18) so that the steering axis (16) of the wheels (10) remain parallel with the vehicle body as the vehicle leans. Steering can be controlled through a steering wheel (14) which, disregarding the influence of body lean, turns the front wheels (10) in a steering direction relative to the turn of the steering wheel which is opposite in sense, e.g. an anticlockwise turn of the steering wheel (14) produces a clockwise turn, when viewed from above, of the front wheels (10). In order to produce a predetermined steering characteristic the ratio between the angle of lean of the vehicle and the responsive angle of turn of the front wheels (10) varies with the forward velocity of the vehicle.
Abstract:
A vehicle frame may comprise a plurality of interlocking tab and slot frame members forming a three-dimensional structure. A custom vehicle frame construction may be specified, designed and built based on a purchaser's selection. The three-dimensional structure may comprise a tab and slot panel to which additional tab and slot frame members are attached. The tab and slot frame members may have an attachment device disposed thereon for attachment of a vehicle component selected by the purchaser of the vehicle frame.
Abstract:
The present teaching provides a three wheel zero emission dumper vehicle (100), the vehicle comprising a chassis (150), the chassis supporting: two fixed front wheels (180), a single steering rear wheel (190), and a load carrying assembly, wherein the vehicle is configured such that a distribution of weight supported by the chassis is such that a centre of gravity of the vehicle is maintained within a triangle formed by the contact of the wheels on the ground in both loaded and unloaded states of the load carrying assembly.
Abstract:
A motorcycle (100) provided with a frame (102), two front steering wheels (12), a steering pipe rotatably connected to the frame (102) and rigidly connected to two supporting assemblies (16), one for each front steering wheel (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). On each of the supporting assemblies (16) the fixed portions of two telescopic elements (22, 24) are constrained. Each pair of telescopic elements (22, 24) is cantilever-mounted as regards the relative steering wheel (12).
Abstract:
Es wird ein Radsegment (1) zur schwenkbaren Anbringung einer Fußplatte (2) an eine Stützwinde (30) beschrieben, wobei das Radsegment (1) ein teilzylindrisches Mantelelement (3) mit einer auf seiner Unterseite (4) gewölbten Abrollfläche (5) und zwei radial auf dem Mantelelement (3) stehende Seitenwände (6a, 6b) aufweist, in deren oberen Abschnitt jeweils ein Anschlagpunkt (7a, 7b) ausgebildet ist. Darüber hinaus ist eine Anordnung eines Radsegmentes (1) an einer Stützwinde (30) geschützt. Der Erfindung lag unter anderem die Aufgabe zugrunde, ein Radsegment (1) bei gleicher Festigkeit kostengünstiger herzustellen. Diese Aufgabe wird erfindungsgemäß mit einem Radsegment (1) gelöst, welches als einstückiges Gussteil gefertigt ist.
