Abstract: An active vibration isolation system for isolating a suspended platform from vibration input to the vibration isolation system base includes an exoskeleton, a rotary actuator, and a drive mechanism separate from the exoskeleton for providing force output from the rotary actuator to the suspended plant. The rotary actuator may include inner and outer rotors which rotate relative to each other. The rotary actuator may be free to translate relative to the vibration isolation system base and the suspended platform, and both the inner and outer rotors may be free to rotate relative to the exoskeleton.

Abstract: The present disclosure provides a machine and mechanism of an electrically controlled low-unsprung-mass wheel unit for vehicles. The design incorporates independent propulsion/braking, axle control, steering, and suspension (IPASS) of each wheel during vehicle movement. The purpose of the design is for a traction-adaptively-optimization (TAO) control which include but not limited as the following: 1) better road surface gripping and ride quality by lower unsprung mass; 2) safer, quicker, and sharper turning ability—transformative turning; 3) adaptive obstacle avoidance; 4) a list of new, unique, and advanced vehicle motion features. The mechanism comprises at least: an axle adjustment that controls the distance of a wheel from the vehicle body, which allows for the outward extension of the wheel via a slider. The slider is connected to a linear actuator, which is powered by the first independent electric motor for track width adjustment.

Abstract: A mounting portion of a battery is provided with a bracket that is placed to face a front face of the battery. A wire harness is placed forward of the battery in a vehicle and is displaced to one side of the bracket in a vehicle width direction, and a terminal that is connected to the wire harness is connected to an electrode. A guiding portion extends from an upper end portion of the bracket to a side portion of the bracket on one side in the vehicle width direction, and the wire harness can be slid along the guiding portion when the wire harness contacts the guiding portion from above. Accordingly, the wire harness is guided by the guiding portion to a position in a routed state in the vehicle width direction.

Abstract: A vehicle includes a frame, an engine, and an exhaust system. The frame includes a main frame and a sub-frame movably attached to the main frame. The sub-frame includes an exhaust bracket that includes a hollow collar. The engine includes an engine casing and an exhaust port. The engine is releasably attached to the sub-frame. The exhaust system includes a conduit, a conduit bracket, and a muffler. The conduit includes an upstream end and a downstream end. The upstream end is connected to the exhaust port. The conduit bracket includes a first end and a second end. The first end is attached to the conduit at a location intermediate the upstream end of the conduit and the downstream end of the conduit. The second end of the conduit bracket is movably attached to the hollow collar. The muffler is attached to the downstream end of the conduit.

Abstract: A drive wheel and suspension for a vehicle for mounting on a steering post to provide both a steering capability and propulsion to the vehicle. The drive wheel and suspension provides a spring suspension for that wheel of the vehicle, as well as what is effectively vehicle body mounting of the propulsion system so as to minimize un-sprung weight and to provide a compact assembly to support a suitable aesthetic and protective fender over the drive wheel and suspension.

Abstract: In an electrically-operated vehicle including rear wheels on right and left sides of a rear portion of a vehicle body, the electrically-operated vehicle includes a motor that drives the rear wheels, a battery 51 that is arranged above the motor, and a lower battery that is placed between the right and left rear wheels. The lower battery and the motor are arranged in a distributed manner over an axle of the rear wheels between a vehicle front side of the axle of the rear wheels and a vehicle rear side of the axle of the rear wheels. An upper end portion of a rear cushion is supported on a vehicle body frame, and the battery and the motor are supported on a lower end of the rear cushion.

Abstract: A heavy vehicle comprising at least four mounted assemblies, intended to draw machinery. The properties of the vehicle satisfy the relationship: ( ? ? - ? · ( 1 - ? ) ) 2 + ( ? - h ? · ? 2 ) 2 > ( h ? · ? 2 ) 2 , where, ??=?/L, ? being the turning radius of the vehicle and L being the wheelbase of the vehicle, K is the proportion of the total vertical stiffness under the front axle with respect to the sum of the total vertical stiffnesses under the front and rear axles of the vehicle, ? is the ratio between the forward offset of the center of gravity and the wheelbase, h? is the ratio between the height of the draft line above the level of ground that forms a horizontal plane and the wheelbase of the vehicle, ? is the ratio between the longitudinal component of the resistive force applied by the drawn machinery to the vehicle, and the weight of the vehicle.

Abstract: A wheelchair suspension is provided. The wheelchair suspension includes a frame, a pivot arm, a front caster, a drive assembly, and a rear caster. The pivot arm is pivotally coupled to the frame. The front caster is coupled to the pivot arm. Movement of the drive assembly in a first direction causes the pivot arm to substantially remain in a first position. Movement of the drive assembly in a second direction urges the pivot arm away from the first position.

Abstract: The rear suspension of a vehicle may include trailing arms connected by a torsion beam at both sides thereof, an in-wheel motor case attached to an outer lateral side of the trailing arm, a brake caliper fixed to the in-wheel motor case, a shock absorber having a lower end fixed to the in-wheel motor case, and a hub bearing fixed to an outer lateral side of the in-wheel motor case.

Abstract: An automotive vehicle suspension unit assembly located near the sides of a vehicle includes a driving axle shaft, a gear box, an electric motor, and a suspension beam. The driving axle shaft, which drives a wheel hub of the vehicle, defines an axis of rotation about which the wheel hub rotates. The gear box includes a pinion shaft connected to a pinion gear which meshes with a ring gear. The pinion shaft is driven by a motor drive shaft which extends outwardly from the electric motor. The motor generates the torque necessary to drive the driving axle shaft. As known, suspension beams extend transversely to the axis of rotation of the driving axle shaft. The electric motor is pivotally attached to the gear box by means of a flexible coupling and is pivotally attached to the suspension beam by means of a movable connection.

Abstract: An engine-drive train subassembly for a golf cart has a generally triangular engine mounting subframe with the engine cantilevered about the rear axles and with a single position front engine mount at the apex of the triangle mounted to permit the rear axles to rotate relative to the cart body, thereby permitting the cart to travel over rough terrain without tilting the cart body. A rubberlike flexible grommet surrounds a pivotable front mount member. This grommet simply rests on a cart frame member in a boltless coupling, and thereby permits movement of the engine frame when the flexible grommet is elastically distorted including a pivoting action caused when one of the rear wheels enters a rut, etc. The rear engine mount is coupled to the cart frame by a pair of springs mounted to the axles adjacent the rear drive wheels. The engine is cantilevered about the rear axles and partly extends therebelow for a low center of gravity.

Abstract: A power unit swing type motorcycle provided with a foot floor positioned lower than a line connecting the center of the front wheel axle and that of the rear wheel axle, and a power unit disposed so that its center of gravity is located substantially on the said line.

Abstract: An industrial truck of the narrow-aisle type having an upright rigidly connected to the frame of the truck and a drive unit pivotably connectible to the frame in certain selected rigid angular relationships in order to vary between predetermined limits the vertical angularity of the upright. The latter connection includes adjustable rigid connection members or struts mounted inwardly of the sides of the truck so that the upright can be securely mounted inwardly of upright members of the frame whereby to increase the lateral rigidity of the upright by adding thereto at least partially the lateral rigidity of the frame.
