A torque smoothing apparatus is utilized in conjunction with a large square baler (LSB), which includes a bale chamber, a plunger mounted for reciprocation within the bale chamber, and an LSB drive line. In embodiments, the torque smoothing apparatus includes a planetary gear train and a flywheel, which is mechanically coupled to the LSB drive line through the planetary gear train. An auxiliary motor having a motor output is mechanically coupled to the LSB drive line through the planetary gear train, while a controller is operably coupled to the auxiliary motor. The controller commands the auxiliary motor to selectively apply torque to the LSB drive line such that the torque applied by the auxiliary motor, taken in combination with a torque contribution of the flywheel, reduces variations in torque demands placed on a vehicle engine as the plunger reciprocates during LSB bale formation.

An example vehicle comprises: (i) a source of direct current power, (ii) at least one electronically-commutated electric motor configured to drive a wheel of the vehicle, and (iii) a voltage bus connecting the source of direct current power with the electronically-commutated electric motor.

A power take-off arrangement for a wave energy converter is described. The arrangement has a gearbox having a first shaft (20) connected to the wave energy converter (1) which is adapted to receive, in use, rotational motion from the wave energy converter. The gearbox has a second shaft connecting the annulus gear (31) to the generator shaft (36). A third shaft (38) is connected to one or more means (39) of applying torque to it. Torque applied by the one or more means (39) may be varied in operation so as to alter the relative rotational velocities and accelerations of the second and third shafts in response to any given rotational velocity or acceleration of the first shaft.

An example vehicle comprises: (i) at least one electric generator that can be electronically-commutated or passively rectified, (ii) at least one electronically-commutated electric motor configured to drive a wheel of the vehicle, (iii) a voltage bus connecting the electric generator with the electronically-commutated electric motor, and (iv) means of controlling voltage level of the voltage bus.

Provided is a non-excitation operable electromagnetic brake that includes a manually operable rotary cam for switching over a rotor to a brake releasing state, but that allows easy recognition of switchover to the brake released state via an operation reaction force and that also allows reliable keeping of the rotary cam under its acting state. Even when an electromagnet is under a non-excited state, when a rotary cam is rotatably operated to an acting position, an acting portion of the rotary cam slidably operates a rotor via a releasing plate to a brake releasing state against springs. The acting portion of the rotary cam is formed linear along a tangent at a center of the acting portion with respect to a rotary cam rotational direction.

A drive device has a superimposed transmission, an input shaft connected a main drive machine, one or more auxiliary drives, a hydrodynamic retarder for braking the auxiliary drive, and an output shaft to be connected to a working machine. The superimposed transmission has a planetary transmission, with the input shaft connected to a ring gear and the output shaft connected to a sun gear. The retarder is incorporated into a lubricating oil system of the drive device in parallel. A feed line branches from the lubricating oil system and leads to the retarder. A return line leads from the retarder and opens into the lubricating oil system. A valve enables the feed line to be released in the event of a rapid disconnection or energy supply failure of one of the drives, and thus the retarder can be filled with oil.

A milling machine includes an engine that generates output power and a rotor that receives the output power from the engine. The milling machine further includes a drivetrain coupled with the engine and the rotor for transmitting the output power to the rotor based on a desired output of the rotor. The drivetrain includes a transmission system operatively coupled with the engine for varying an output of the rotor without altering a load on the engine. The transmission system includes a hydrostatic arrangement operatively coupled with the engine. The transmission system also includes a mechanical arrangement coupled with the engine and the rotor arrangement. The drivetrain also includes a power transmitting arrangement coupled with the transmission system. The drivetrain further includes a gearbox coupled to the power transmitting arrangement and the rotor, such that the power transmitting arrangement is disposed between the transmission system and the gearbox.

Gearwheel transmission comprising a first stage and a second stage, the second stage being a differential gearing comprising a planetary gear train system which is executed in a quasi duplicated form, wherein a first component is forming a torque resisting means, wherein a second component is interconnected or interacting with an output shaft, the overall transmission efficiency in the first stage being higher than in the second stage and/or the overall capacity for transmitting torque in the second stage being higher than in the first stage.

A dual-mode active rear-wheel steering device, including: a steering motor, a main shaft, an intermediate gear, a transmission gear, a planetary gear coupling mechanism and a mode switching assembly. An output end of the steering motor is provided with a first input gear. An end of the main shaft drives a first rear wheel to rotate by a two-stage gear transmission system and a first rear-wheel motion conversion mechanism, and the other end of the main shaft drives a second rear wheel to rotate by the planetary gear coupling mechanism and a second rear-wheel motion conversion mechanism. The intermediate gear, the transmission gear and a sun gear of the planetary gear coupling mechanism are provided on the main shaft. The intermediate gear meshes with the first input gear.

An agitation/defoaming device is provided, which can independently control revolving and rotational motion and can change a rotational direction relative to a revolving direction without a two-system rotary drive. The apparatus includes a rotary driving source, a braking device for rotary motions; first and second rotors revolved around revolving shaft, and first and second rotational bodies and container holders pivotally supported by the first rotor. A braking force is applied to the second rotor revolving along with the first rotor, generating a rotational motion, which is transmitted to either the first or second rotational body according to the revolving direction of the first rotor. The rotational motion is then transmitted from the first or second rotational body to the container holder through the first rotational body, thereby transmitting to the object the rotational motion according to the revolving direction while revolving the object.
