Abstract: A suspension system for the drive wheel or wheels of a human powered vehicle provides a direct and rigid connection between the mounting of a driving pulley and the mounting of a driven pulley for rotating the drive wheel or wheels. A single and simple pivot junction allows the swing necessary for suspension of a rigid rear triangle carrying both of these mountings. A pressurized gas bag or a spring system is used to provide a biasing force between the rear triangle and a front triangle. This allows the maximum efficient use of human effort and avoids compromising the ideal operator position on the vehicle, as well as providing adjustable shock absorbing capabilities.

Abstract: A bicycle, motorcycle or the like is fabricated from a pair of frame sections. A front frame section includes the front fork and wheel, handlebar assembly and seat. A rear frame section includes the crank assembly, pedal assembly and the rear stays and wheel. A shock absorber resiliently couples the front and rear frames to one another intermediate the crank assembly and seat. The lower terminus of the shock absorber is secured to a center support stay of the rear frame, the upper terminus of the shock absorber being coupled to one plurality of selectable locations on a diagonal support of the front frame. The point of coupling alters the relative stiffness of the suspension to compensate for the load imposed on the bicycle seat. The front and rear frames are pivotally coupled to one another forwardly from the lower terminus of the shock absorber in a manner which will permit adjustment of the force required to activate the suspension.

Abstract: There is disclosed a shock absorber which is contained within the head tube of a bicycle. The shock absorber has an outer cylinder that is rotationally received within the head tube and secured at its upper end to a handlebar support member, such as a gooseneck. An inner cylinder is slidably received within the outer cylinder and secured at its lower end to the fork that supports the front wheel. Each of the cylinders has longitudinal grooves, the inner cylinder having longitudinal grooves on its outer surface which align with longitudinal grooves on the inside wall of the outer cylinder. A plurality of bearing balls are received in the tracks which are formed by the longitudinal grooves of the cylinders and a thin-wall bearing retainer is concentrically received between the inner and outer cylinders having a plurality of apertures at predetermined spacing which are aligned along the bearing tracks, each of the apertures capturing one of the bearing balls.

Abstract: A bicycle seat assembly permits a bicycle seat to rotate or be laterally displaced short distances in order to absorb movement by the user's body and to increase the comfort of the user while riding a bicycle.

Abstract: A bicycle frame includes a front frame having a cross bar, a rear frame including a center post, and a leaf-spring-like flexible plate interconnecting the cross bar to the center post. A shock-absorbing member is pivotally secured at its ends to the front end of the cross bar and to the bottom of the center post in a triangular arrangement. The shock-absorbing member includes a coil spring that stores energy as the shock absorber member is extended in a first direction and the frame is expanded, which energy is returned to the bicycle frame upon relaxation of the coil spring. However, the shock-absorbing member is substantially incompressible in the opposite direction so that it prevents the front and rear frames from collapsing undesirably. This also allows forces to be transmitted from the front frame to the rear frame through the shock-absorbing member in the second opposite direction thus taking some stress off of the flexible plate.

Abstract: A suspension system includes a long-travel suspension configuration for the seat of a bicycle. For instance, this long-travel arrangement could take the form of either a spring-loaded telescoping seat tube mechanism or a single-leaf spring extending horizontally from the seat to a forward attachment point fairly near the steering head. In order to prevent the constant bobbing up and down that this type of suspension usually causes when the rider is pedaling, the suspension also includes a second suspension mechanism which allows the pedal-and-crank assembly to move substantially in unison with the seat. However, this coordinated suspension movement occurs only over bumps and obstacles of relatively moderate size because the total suspension travel of the pedal-and-crank assembly, on a sort of reversed swingarm arrangement, is only about half the overall travel of the seat.

Abstract: Mountain bicycle suspension having a shock absorber whose function can be selectively disabled by blocking normal compression and extension response to optimize suspension characteristics for different riding conditions, e.g. rigid suspension for efficient use of energy during hard acceleration and hill climbing, and soft suspension for control on downhill runs and cruising under smooth terrain conditions.

Abstract: A bicycle shock-absorbing apparatus includes an upper tube telescopically received in a lower tube. A plurality of compressive members are positioned inside the upper tube. A socket bolt member having a socket portion and a rod portion is mounted on a mount member of the lower tube by its rod portion while allowing its socket portion to be slidably received in a lower portion of the upper tube and to contact against a bottom one of the compressive members. When the bicycle receives a shock from an uneven terrain, the upper tube slides downward inside the lower tube while the compressive members therein will be compressed, thereby absorbing the shock.

Abstract: This invention relates to a front wheel resilient suspension system for a chainless bicycle where a horizontal bar member extends between a main bar member located under the bicycle seat to a horizontal bar connector mechanism which is resiliently mounted to both the horizontal bar member and the handlebar of the chainless bicycle.

Abstract: The headset of a conventional mountain bicycle is modified to permit the load supported by the front wheel to be transferred to the bicycle frame through a column of compressed air to minimize shock and vibration to the rider when riding over rough ground. A valve matching those in the mountain bicycle tires is located on the steering axis above the handle bar stem and permits the compressed air pressure to be adjusted for different rider weights through use of a conventional bicycle pump. The typical air pressure required with the shock absorber unloaded is less than the tire pressure. The shock absorber design should permit hard use for long periods without maintenance.

The anti-pitch system includes a torsion rod which links the rear swing arm to the forward control arm. The torsion rod resists unequal angular displacements of the control arm and the swing arm relative to the chassis, thereby resisting pitching motions such as normally occur during hard braking of the front wheel or during hard acceleration. The torsion rod does not however affect substantially equal displacements of the front and rear suspensions, that is, substantially vertical motions of the motorcycle chassis, such as occur in response to varying weight loads on the motorcycle or in response to dips or rises in a road. The system is particularly adapted to a motorcycle having a one-sided front suspension system.

A pair of upper and lower control arms extend forwardly from the body of the motorcycle and are attached by universally pivotable ball joints to a kingpin which extends along one side of the front wheel. The front wheel includes an offset hub and is journalled in a cantilevered arrangement to a bearing assembly which is affixed to the lower end of the kingpin and which is positioned at the center of the wheel. The control arms are hinged to the body and are appropriately sprung and damped so that the kingpin and front wheel swing vertically in suspension travel with respect to the body in response to weight and shock loads on the front wheel. The kingpin is connected to a handlebar assembly by means of a telescopic splined steering column. A variety of springing and damping mechanisms may be adapted to the suspension system.

The rear suspension system can be mounted in a relatively narrow space, and even with devices of relatively large capacities mounted thereabout, it can exhibit its damping characteristics satisfactorily.

Abstract: This disclosure relates to apparatus for preventing the nose dive produced when a motorcycle is sharply braked. The motor cycle includes a frame, front and rear wheels, and front and rear mounting means for connecting the wheels to the frame. The anti-nose-dive apparatus includes a generally U-shaped torsion bar having a center portion and front and rear arms. The center portion is rotatably mounted on the frame, the front arm is connected to the front mounting means, and the rear arm is connected to the rear mounting means. When the vehicle is moving and is sharply braked, the front end of the frame tends to move down relative to the front wheel. This action twists the torsion bar causing the rear mounting means to tend to rise. The reaction on the torsion bar causes the rear end of the frame to move down relative to the rear wheel, thereby reducing the amount of the nose dive.

Abstract: A vehicle suspension system for the chassis of motorcycles and like vehicles comprising:(a) a support frame adapted to receive a wheel axle at the lower portion thereof, and being movably mounted with respect to the chassis both in the longitudinal median plane of the cycle as a result of movement of the suspension system as well as in rotation around an axis for steering;(b) upper and lower frames for controlling the position of the support frame in the longitudinal median support plane positioned between the chassis and the support frame;(c) a shock absorber positioned to elastically maintain the support frame with respect to the chassis in the longitudinal median plane whereby the wheel axle moves along a trajectory determined by the frames as a function of the forces being exerted on the cycle; and(d) an independent mechanical element connecting the support frame to handlebars, and being independent of the frames to allow control of the rotational position of the support frames around its axis.

Abstract: The main frame member of a motor-cycle mounts a steering head supporting the front fork, and at its rear end also a rear fork. Both forks are provided with shock absorbers and especially with motor-cycles suited for moto-cross running the movements of the forks in action may be considerable. The combined center of gravity of motorcycle and rider will change due to road and driving conditions, which means that the load upon the shock absorbers will change continuously. Undue compression or expansion of the front fork shock absorbers will alter the inclination of the front fork in relation to the plane of the ground, which makes steering difficult. To counteract such alterations the steering head includes a hoirzontal pivot and lever means connected to the rear fork for adjusting the position of the vertical axis of the steering head by causing a rotation of the head about the horizontal pivot in response to the swinging of the rear fork.

Abstract: This disclosure provides an oil brake device for use in the bicycle in which a saddle support is resiliently suspended independent of a main body frame so as to prevent the transmission of shock and vibrations of front and rear wheels in bicycle riding.
