Abstract:
A low horsepower transmission is disclosed. In one embodiment, a drive shaft is operably coupled to a prime mover and a driven shaft is axially aligned with the drive shaft and operably coupled to a rotary load. Two sets of geared wheels are aligned and rotatably mounted to opposite sides of the drive shaft and the driven shaft. A shuttle clutch positioned on the driven shaft is operable to reciprocate between mating engagement with a clutch associated with the first set of geared wheels and a clutch associated with the second set of geared wheels. The engagement of the shuttle clutch determines which set of geared wheels will transmit torque.
Abstract:
An apparatus is provided in one example embodiment and includes a power management module configured to receive data associated with travel being proposed by an end user of an electric vehicle. The power management module is configured to suggest a starting time for the travel based on time of use (ToU) rates for electricity consumption and a current level of power in the electric vehicle. In more specific embodiments, the data associated with the travel includes a starting location, an ending location, and a proposed drive time. In other embodiments, the power management module is further configured to interface with a mapping tool in suggesting the starting time for the end user. The power management module can be configured to obtain the ToU rates from a utility, and the ToU rates are provided as a function of time.
Abstract:
A marine reduction gearbox, or transmission, is provided with variably engageable clutches connected in torque transmitting relation between a prime mover and a propeller shaft. These variably engageable clutches permit the prime mover to be connected to the propeller shaft in partial torque transmitting association. One advantage of this type of apparatus is that the prime mover can be partially loaded during crash reversal procedures while the propeller shaft is still and inhibited from rotating by the action of a brake. This preloading of the prime mover while at idle speed increases the power output of the prime mover and prepares it for an eventual connection to a rotatable propeller shaft with the brake disengaged or partially disengaged. This procedure prevents the stalling of the prime mover, especially when the prime mover is a high break mean effective pressure engine. A second advantage of the use of a variably engageable clutch is that a marine vessel can be operated at speeds lower than that which would result from direct connection between a prime mover operating at idle speed and a propeller shaft.
Abstract:
A bi-directional torque transmission unit (1) comprises an input shaft (2) connectable to a prime mover and provided with an input drive gear wheel (3), first and second driven shafts (4, 4A) each having a driven gear (5, 5A) constantly in mesh with the input drive gear wheel (3), so that they are rotatable in the same direction, a hydraulically actuated and modulated clutch (7, 7A) interconnecting each driven shaft (4) with an intermediate, output shaft (6, 6A) and a final, output shaft (11) connectable to a load, and both the first and the second output shafts (6, 6A) having an output gear (12, 12A) whereby selective or simultaneous engagement of one or other of the modulated clutches (7, 7A) transmits torque to the final output shaft (11).
Abstract:
A marine reversing gearing having a drive shaft, a forward clutch, a forward pinion coaxially arranged with respect to the drive shaft and capable of being coupled therewith by means of the forward clutch for forward travel. Two intermediate gears continuously mesh with the forward pinion, there also being provided two intermediate pinions which are rigidly connected with a respective one of the intermediate gears. A large gear continuously meshes with both intermediate pinions. There are also provided a reverse clutch and a rearward pinion which is coaxially arranged with respect to the drive shaft and can be coupled therewith by the reverse clutch for rearward travel, and two reversing pinions are driven by the rearward pinion. The intermediate gears meshing with the forward pinion exclusively transmit power as forward gears during the forward travel. Both of the reversing pinions mesh with the rearward pinion and with a respective rearward gear, and each of both intermediate pinions also are fixedly connected with one of the rearward gears.
Abstract:
A reverse and reduction gear for ships wherein three clutch units are arranged arcuately around a large gear mounted on a thrust shaft, each clutch unit comprising an auxiliary shaft, loosely carrying driving and driven gears, and a clutch interposed between the two gears, and the driving gear of the center clutch unit is coupled to the input shaft and meshed with the driving gears of the clutch units on both sides, said driven gears of the three clutch units being meshed with the common large gear on the thrust shaft.
