ELECTRIC WORK VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18734389 titled 'ELECTRIC WORK VEHICLE
Simplified Explanation
The patent application describes an electric work vehicle with a motor controller, power take-off shaft, power distributor, and hydraulic continuously variable transmission to control and distribute rotational power efficiently.
- The electric work vehicle includes a motor controller to regulate the motor's rotation speed.
- It has a power take-off shaft that can connect to a work device and transmit rotational power from the motor.
- A power distributor distributes rotational power output from the motor to the hydraulic continuously variable transmission and the power take-off shaft.
- The hydraulic continuously variable transmission adjusts the speed of rotational power input and sends it to a travel device.
- The motor controller executes maintenance control to maintain the motor's output rotation speed at the desired level.
- Manual operation of a speed change operation tool can alter the transmission state of the hydraulic continuously variable transmission during maintenance control.

A hydraulic continuously variable transmission allows for smooth speed adjustments and efficient power transfer, leading to improved performance and control in various work applications.
Original Abstract Submitted
An electric work vehicle includes a motor controller to control a motor, a power take-off shaft capable of being connected to a work device and transmitting rotational power from the motor to the work device, and a power distributor to distribute rotational power output from the motor to a hydraulic continuously variable transmission and the power take-off shaft. The hydraulic continuously variable transmission changes a speed of rotational power input to the hydraulic continuously variable transmission, and outputs the resulting rotational power to a travel device. The motor controller is configured or programmed to execute maintenance control to maintain an output rotation speed of the motor at a rotation speed corresponding to a target rotation speed of the power take-off shaft. A transmission state of the hydraulic continuously variable transmission can be changed according to manual operation of a speed change operation tool while the maintenance control is executed.
