A utility cart includes a suspension having an integral perch bracket having a plurality of legs structured to straddle an axle of the utility cart, and can include an opening into which a spring pin (e.g. a pin of a leaf spring) can be inserted. The perch bracket can alternatively include a brake cable attachment feature located on an end of the bracket. In one form the end can extend from one leg and be folded toward an opposing leg. The perch bracket can be cut from sheet stock of material, and stamped into final or near final form. In one embodiment a threaded nut can be attached to the legs of the perch bracket.

A golf cart vehicle is disclosed having a suspension that includes a single suspension device that provides for a plurality of functions. In one embodiment the single suspension device includes a plurality of transverse mounted leaf springs that are longitudinally spaced apart from one another to provide a spring and control arm combined effect. The leaf springs can be coupled to a wheel, such as through a steering knuckle via a ball and socket joint. The leaf springs can further be mounted to a chassis via clamps. In one embodiment the clamps are connected to the leaf springs through resilient bushings which can be spaced apart from one another to provide an anti-roll bar effect.

A vehicle includes a chassis, a suspension system, and a steering system operably coupled to the chassis and to the suspension. The chassis includes a mounting member that has a first elongated slot. The suspension system includes a beam that is pivotally coupled to the mounting member. The steering system includes a first axle, a second axle, a tie bar that extends between first and second tie bar ends, and a slider. The first and second axles are pivotally coupled with respect to the beam. The tie bar is operably coupled to the first and second axles and includes a second elongated slot that is configured to overlie the first elongated slot. The slider is positioned in the first and second elongated slots, and is configured to move in the first and second elongated slots to select a ratio of the tilting of the mounting member to the steering of the first and second axles.

Children's ride-on vehicles having a drive assembly that is selectively configured between a plurality of drive configurations, such as responsive to user inputs via user input devices, and a ground detection system that is adapted to detect when at least one of a plurality of wheels loses contact with the ground surface. The ground detection system may be adapted to restrict the plurality of drive configurations responsive thereto. This restriction may be automatic responsive to loss of contact of the at least one of the plurality of wheels with the ground surface, and it may be made regardless, or independent, of user inputs that otherwise would select and/or enable one of the restricted drive configurations.

A transporter that includes a platform for supporting a load and at least one primary ground-contacting element. The transporter includes an actuator for applying torque to the at least one primary ground-contacting element for propelling the transporter with respect to a surface. The transporter also includes a controller for controlling the actuator, the controller includes an input for receiving specification by a user of a desired direction of travel based on a position of a member with respect to a fiducial axis, a differentiator for calculating a rate of change of the position of the member with respect to the fiducial axis, and a processor for generating a yaw command signal based at least on the position of the member and the rate of change of the position of the member which is weighted based on the level of experience of the user.

A go-kart drive assembly with an internal combustion engine in the form of a reciprocating-piston or rotary-piston engine as a power source is described. The drive assembly includes a spur-gear reduction gearing between the internal combustion engine and a rear-wheel drive shaft of the go-kart. The spur-gear reduction gearing and the crank shaft (17) of the reciprocating engine or the engine shaft of the rotary-piston engine (17a) are accommodated in a common housing (10) that is preferably closed. The space or spaces (a, b) between the shafts of the spur-gear reduction gearing (27, 29; 30, 33) is fixed in the housing (10) so as to be invariable. The driving gear wheel (27) of the gearing (26) is mounted on the crank shaft (17) or the engine shaft (17a) and the driven gear wheel (33) of the gearing (26) is mounted on the rear-wheel drive shaft (6).
摘要:
A transporter for transporting a subject over a surface that may be irregular. The transporter includes a support platform for supporting a load, the loaded support platform defining fore-aft and lateral planes and characterized by a load distribution. A plurality of ground contacting elements are coupled to the support platform such that the transporter is statically stable with respect to tipping in the fore-aft plane. At least one of the plurality of ground contacting elements is driven by a motorized drive arrangement. A sensor module generates a signal indicative of the load distribution. Based at least on the load distribution, a controller commands the motorized drive arrangement.
摘要:
A modified racing vehicle having dimensions such that it can run on a track suitable for a conventional go-kart and which has substantially the characteristics of a single seater formula racing car. The vehicle has no differential on its rear axle (2) and no suspension on its rear and front axles (5) but is provided with weight transfer structure to compensate therefor. The steering geometry of the vehicle is arranged such that, for the radially outer steerable wheel with reference to a turning centre, a castor angle of the kingpin axis increases and the kingpin axis is inclined into the turn as the steering member (6) pivots and the outer steerable wheel is lifted upwards forcing the chassis (1) down whereby a downward force is exerted through the chassis (1) to a non-steerable wheel (4) that is the radially outer with reference to the turning center.

A go-kart construction uses a unibody construction wherein the body serves as a part of the suspension as well. The molded body is made from a flexible yet resilient material such as fiberglass or a suitable plastic such that it has sufficient flexion about a longitudinal axis to allow some twisting deformity without sagging when a passenger is supported in the vehicle. The forward suspension is mounted only to the forward portion of the molded body and includes a transverse member on which vertical bearings for the steerable guidance wheels are mounted, however, the transverse member is connected to the flexible body only by a pair of longitudinally extending members which are freely rotatably connected to the transverse member at their forward ends.
摘要:
A suspension unit for each rear wheel of a motor powered off-road four wheeled vehicle comprising a suspension arrangement with the inner members constructed for mounting on a fixed shaft secured to the vehicle and the outer casing carrying a swing arm terminating in a swivel joint to be secured to a single rear wheel axle and a pair of such a units in combination with a drive chain and sprocket device for the single axle and a braking system having at least one disc brake for fixed mounting on the rear axle with caliper carried on an operating arm supported from a bearing to be mounted on the same axle.
