Provided is a versatile platform having high versatility without increasing its weight. A versatile platform is used for a transport vehicle for crops, a security robot, or the like. The versatile platform includes a first axle, a second axle, a pair of first wheels and, a pair of second wheels and, motors and for driving the four wheels, a first steering portion for steering the first wheels, a second steering portion for steering the second wheels, and a battery support portion. A vehicle body frame integrally joins the first axle and the second axle and supports a work unit for performing operation. The vehicle body frame includes horizontal bar members and vertical bar members and is formed into a frame shape. The whole upper surface of the vehicle body frame is exposed to the outside.

Disclosed herein is an adjustable suspension mount system that includes a subframe for attachment to a suspension device of a vehicle. The system further includes a first and second mount link for attaching the subframe to a frame of a vehicle. A positioning device for attaching to the frame of the vehicle and the subframe is also included. The adjustable suspension mount system may also attach to a second suspension device of the vehicle as well as other further suspension devices. Further disclosed is a vehicle having the adjustable suspension mount system, a kit for providing the adjustable suspension mount system, and methods of using the adjustable suspension mount system for raising and lowering a vehicle.

A scooter has a load-carrying deck, a steering rod for steering a front wheel, two outriggers arranged on opposite sides to be pivotable between retracted stowed positions and extended support positions. Each outrigger has a wheel mounted movably on the outrigger to move between a stowed position and a ground-contacting support position. The outriggers when in their support position form a wider loading surface than the deck alone. A control arm is attached to the steering rod for movement between a folded/stowed position lying adjacent to the rod and an operating position extending forward from the steering rod. A sensor detects movement of at least a section of the control arm and, in response thereto, provides control inputs to an electric motor driving a rear wheel.

There is provided a three-wheeled vehicle that can maintain the ground contact surfaces of wheels and the road surface in contact with each other at all times, and that can suppress direct transmission of most of an impact from the road surface to a platform. First to third wheels are attached to a body frame that is rigid. The platform and the body frame are connected to each other by a connecting structure. First to third three degree of freedom non-restricted connecting mechanisms and first to third three degree of freedom restricted connecting mechanisms that form the connecting structure are deformed to allow the platform to make a bouncing motion, a rolling motion, a pitching motion, and a combined motion thereof within a restricted range when an impact is applied to the body frame from the road surface.

A tunable hydraulic vibration damping mount comprises a universal outer housing, inner sleeve, main spring assembly, bottom compliance assembly, and inner bushing. Each of a plurality of flow channel members comprises a cylinder having a common inner diameter, a common outer diameter, and a helical track having a cross-sectional area and a length defining a volume of the helical track. The helical track of each flow channel member defines a different volume. A selected flow channel member is positioned between the inner bushing and the outer housing and between the main spring assembly and the bottom compliance assembly. The selected flow channel member provides a selected dynamic performance of the damping mount.

A self-stabilizing vehicle includes a mass gyroscope which is fixed at an occupant compartment chassis corresponding to a portion where occupants sit. The occupant compartment portion may tilt outwards in response to the centrifugal force. If the vehicle has three or more wheels, the load is evenly distributed on the left wheel and the right wheel which move oppositely up and down about an effectively centrally-mounted shaft pin. Further, the present disclosure proposes a method for operating the self-stabilizing vehicle. According to the self-stabilizing vehicle and the operating method thereof, a vehicle having a narrow body may be used. When the vehicle undergoes external forces such as the centrifugal force and the crosswind, the occupant compartment can maintain the vertical stability even though the wheels may slide sideways.

A straddle-type vehicle includes a vehicle body frame; a power unit supported by the vehicle body frame; a seat mounted at a position higher than the power unit; a handle bar mounted at a position more forward than the seat; a pair of front wheels spaced apart from each other in a vehicle width direction; a pair of suspensions spaced apart from each other in the vehicle width direction and connecting the pair of front wheels to the vehicle frame; and a vehicle body vibration control damper including end portions connected to a first attachment portion and a second attachment portion, respectively, mounted on the vehicle body frame so as to be spaced apart from each other in a vehicle front-back direction, and mounted so as to extend in the vehicle front-back direction with at least a portion thereof located between the pair of suspensions.

A spring supported tray for mitigating a dominant frequency imparted thereto is provided. The spring supported tray includes a tray including a topside and underside, and configured to support an object on the topside, and N springs supporting the tray, N being a positive integer. A first end of each of the N springs is disposed at the underside of the tray. A second end of each of the N springs is disposed so as to receive vibrational motion imparted to the second end of each of the N springs from a source of the vibrational motion, the vibrational motion having a dominate undesired frequency Each of the N springs has a spring constant k defined by the equation:

[00001]$k=\frac{f_n^2.Math.4.Math..Math.{}^2.Math.w}{\mathrm{Ng}}$

where w denotes the collective weight of the tray and the object, g denotes the force of gravity, and f.sub.n denotes a natural frequency of the spring supported tray supporting the object, wherein f.sub.n is a lower frequency than the dominate undesired frequency f.sub.dom.
