A radio-controlled vehicle, in particular a radio-controlled lawn mower, comprising: a frame; an engine; at least one rolling unit to cause the radio-controlled vehicle, in use, to move on a ground; a drive system for each rolling unit; a remote control; a control unit, which exchanges signals with the remote control, the engine and each drive system; a belt drive assembly which is interposed between the engine and each drive system and is operated by the engine so as to cause the rotation of each drive system.

Methods and systems are provided for an accessory drive device. In one example, the accessory drive device comprises an input belt coupled to a pulley of a two-speed device and an output pulley coupled to an output belt configured to provide energy to an alternator or a belt integrated starter generator.

A camera cleaning device 10 includes an air intake port 12, a camera 13, and a flow path 14. The air intake port 12 is located in an internal combustion engine room ER of a mobile body 11. The camera 13 is mounted on the mobile body 11. The flow path 14 allows a fluid to flow from the air intake port 12 to an optical system of the camera 13.

A fire apparatus includes a chassis, a cab coupled to the chassis, a pump system coupled to the chassis and positioned at least partially behind the cab, and a driveline. The driveline includes a prime mover positioned beneath the cab and coupled to the chassis, a transmission, a sandwiched power take-off unit, and a brake system. The sandwiched power take-off unit is positioned between (a) the prime mover and (b) the transmission and the pump system. The brake system is positioned between the sandwiched power take-off unit and the pump system.

A power take-off includes a housing including a mounting surface that is adapted to be secured to a source of rotational energy. The mounting surface has an opening therethrough. An input mechanism includes an input gear that has a portion that extends outwardly from the housing through the opening provided through the mounting surface and is adapted to extend within and be rotatably driven about an input gear rotational axis by a driving gear contained within the source of rotational energy. An output mechanism is disposed within the housing and includes a driven gear that is rotatably driven about an output gear rotational axis by the input gear of the input mechanism. The rotational axis of the input gear and the rotational axis of the driven gear are movable relative to one another so as to minimize the transmission of torque transients and other vibrations therethrough during operation.

A motor vehicle includes a motor and a transmission including a drive shaft driven by the motor and connecting the motor to the transmission, a first output shaft extending along the vehicle longitudinal axis in the one direction, which first output shaft is connected to a wheel axle by a first differential, and a second output shaft extending along the vehicle longitudinal axis in the opposite direction, which second output shaft is connected to a second wheel axle by a second differential, characterized in that the drive shaft is disposed in the longitudinal axis of the motor vehicle and the first and the second output shaft are disposed on opposing sides relative to the longitudinal axis of the motor vehicle with identical spacing with respect to the longitudinal axis of the motor vehicle.

Methods and systems for a vehicle transmission are provided. In one example, a vehicle transmission system includes a first planetary gear set rotationally coupled to a second planetary gear set and a first electrical machine rotationally coupled to a gear in the first planetary gear set. The vehicle transmission system further includes a second electrical machine rotationally coupled to a gear in the second planetary gear set and a first clutch configured to selectively disconnect the first and second planetary gear sets from a drive axle.

Methods and systems for a vehicle transmission are provided. In one example, a vehicle transmission system is provided that includes a first planetary gear set rotationally coupled to a second planetary gear set, a first electrical machine rotationally coupled to a sun gear in the first planetary gear set, and a second electrical machine rotationally coupled to a sun gear in the second planetary gear set. The transmission system also includes an inter-axle differential including a third planetary gear set rotationally coupled to a first axle and a second axle and selectively rotationally coupled to the first planetary gear set and the second planetary gear set, wherein the inter-axle differential is configured to selectively enable and disable speed differentiation between the first and the second axles.

Overload protection systems and methods are provided for controlling the amount of energy delivered to the drivetrain of work vehicles including axles, transmission, and other components thereof including for vehicles using power boost. A sensor in operative communication with a primary power equipment unit driving a transmission of a work vehicle generates a torque signal representative of torque delivered to the transmission by the primary power equipment unit. The overload protection method and system uses the torque signal to control the torque delivered to the transmission of a work vehicle by the primary power equipment unit.
