ELECTRIC DRIVER FOR WHEELED GROUND SURFACE MODIFYING MACHINE
A battery powered driver for propelling a wheeled ground surface modifying machine includes at least one wheel contacting a ground surface, a battery powered electric motor, control circuitry configured to manage delivery of electrical battery power to the electric motor to control a sped of the driver, at least one pedal attached to a pedal axle and tiltable in each of a forward and rearward direction with respect to the pedal axle, and at least one pedal tilt sensor configured to output one or more signals to the control circuitry indicating a degree of tilt of the at least one pedal. The control circuitry is configured to control the electric motor to accelerate the driver forward based on the one or more signals indicating a forward tilt of the at least one pedal, the electrical battery power delivered to the electric motor for forward acceleration proportional to a degree of forward tilt of the at least one pedal, and to control the electric motor to accelerate the driver rearward based on the one or more signals indicating a rearward tilt of at least one pedal, the electrical battery power delivered to the electric motor for rearward acceleration proportional to a degree of rearward tilt of the at least one pedal.
Closed-loop electronic slipping belt transmission speed control system for a walk-behind lawn mower
A transmission speed control system for a walk-behind lawn mower includes a transmission, a transmission positioning assembly, and an electronic control unit. The transmission is tiltable about and operably engaged with a drive axle shaft. The transmission positioning assembly tilts the transmission between first and second angular positions. A belt tension between a drive belt and a transmission pulley of the transmission continuously increases from a minimum belt tension when the transmission is in the first angular position to a maximum belt tension when the transmission is in the second angular position. The rotational drive force exerted on the drive axle shaft by the transmission and a resulting driving speed of the lawn mower vary proportionally with the belt tension. The electronic control unit controls the transmission positioning assembly to tilt the transmission based on target and detected driving speeds.
TRANSPORT TRAILER WITH ON-BOARD CHARGING STATION
A transport trailer, method of construction of the trailer, and method of operation of the trailer that supplies electrical power to power equipment during transport, the transport trailer includes a power coupling for receiving power from a vehicle towing the transport trailer and conduit for transmitting the power from the vehicle to a power charging arrangement, the power charging arrangement comprising a power transmitting pad compatible with a power capture resonator used to charge an on-board battery of power equipment.
Safety device for motor vehicle
A safety device for motor vehicle includes a microprocessor having set therein a tilt angle default value, a controller coupled with the ignition device and brake device of the motor vehicle, an angle sensor mounted to the body of the motor vehicle and an operator sensor installed in the directional control device. The microprocessor activates the controller to turn off the ignition device and to actuate the brake device if the motor vehicle is tilted excessively or when the operator goes out of the sensing range of the operator sensor, avoiding danger.
CLOSED-LOOP ELECTRONIC SLIPPING BELT TRANSMISSION SPEED CONTROL SYSTEM FOR A WALK-BEHIND LAWN MOWER
A transmission speed control system for a walk-behind lawn mower includes a transmission, a transmission positioning assembly, and an electronic control unit. The transmission is tiltable about and operably engaged with a drive axle shaft. The transmission positioning assembly tilts the transmission between first and second angular positions. A belt tension between a drive belt and a transmission pulley of the transmission continuously increases from a minimum belt tension when the transmission is in the first angular position to a maximum belt tension when the transmission is in the second angular position. The rotational drive force exerted on the drive axle shaft by the transmission and a resulting driving speed of the lawn mower vary proportionally with the belt tension. The electronic control unit controls the transmission positioning assembly to tilt the transmission based on target and detected driving speeds.
ELECTRIC POWER EQUIPMENT
Provided is electric power equipment that allows a battery to be installed and removed with ease. The electric power equipment (1) includes a main body (2) defining a battery receiving recess (40) having an open upper end, and a battery (20) configured to be received in the battery receiving recess, wherein an upper part of a front end part of the battery is provided with a projection (108) projecting in a forward direction, and a rear end part of the battery is provided with a grip, and wherein an upper edge of the front end part of the battery receiving recess is provided with a supporting surface (36) configured to support a lower surface of the projection at least when the battery is being removed from the battery receiving recess.
TOTAL TASK VEHICLE
A total task vehicle (TTV) may operate indoors to move a variety of different types of materials and accomplish a variety of different types of tasks, using tools and accessories powered by/connected to the TTV. One or more high power density (HD) battery packs may provide both 240V DC to 380V DC and 120V AC power to propel the TTV and also to function as a generator for tools and accessories attached to the TTV. A high torque/high speed convertible drive system may allow the TTV to operate in a ride-on mode, a walk-behind mode, providing for flexibility and adaptability in use of the TTV.
Steering responsive speed-controlled buggy
A steerable, self-propelled cart for safely delivering heavy loads, such as concrete, within job sites with unlevel, irregular, or sloped terrain. A cargo bucket is tiltable over front drive wheels for transporting and dumping cargo. Hydraulic drive motors driven by a hydraulic pump propel rear wheels at a selectable speed. Steering handlebars rotate a steering column that turns the rear wheels. A throttle cable extending from the handlebars controls the throttle setting by pivoting a throttle lever mounted on the hydraulic pump. Limiting linkages extend from flanges on an anchor bracket secured to the steering column to a bridge on the throttle lever. As the steering column rotates, the limit linkages are wound partially about it, pivoting the throttle lever by pulling on the bridge, reducing pump speed. Heavy steering displacements will retract the throttle lever to reduce cart speed notwithstanding the previous speed setting chosen by the operator via the cable.
TRACTOR HAVING DUAL HYDROSTATIC DRIVE WITH SINGLE HAND CONTROL AND ATTACHMENT ADAPTER FOR POWERED ATTACHMENTS
A tractor has a base for supporting a motive power source, left and right driven wheels, and left and right transmissions for the respective left and right wheels; a handle structure coupled to the base for grasping by an operator from behind the tractor; a drive system for driving each of the left and right transmissions with motive power from the motive power source; wherein the left and right transmissions are hydrostatic transmissions, further having a speed regulator control lever on each transmission that allows seamless control of the transmission from reverse speed through neutral into forward speed; and a transmission control coupled to each speed regulator control lever; further wherein there is a longitudinally disposed space between the left and right transmissions, and a power take off shaft is disposed in the space extending anteriorly and driven by the motive power source for powering a powered attachment arranged to be attached at the anterior of the tractor, further including a shaft extension of said power take off shaft extending posteriorly for driving a rear power take off for powering a rear mounted powered attachment.
