Abstract: A direction-reversing device includes at least one input shaft, an output shaft, and direction-reversing element with a clutch sleeve including a moving clutch sleeve, mounted to move axially on one of the shafts carrying it to enable occupying forward and reverse positions. This device also includes a blocking element that is driven in rotation by the input shaft that carries the moving clutch sleeve, whereby this blocking element is mounted to move between the off position, in which the moving clutch sleeve is able to switch from one operating position to the next, and the on position, in which the blocking element forms an obstacle that prevents the switching of the moving clutch sleeve from one position to the next, being able to switch automatically from the off position to the on position when the input shaft is driven at a speed of rotation that exceeds a predetermined threshold value.

Abstract: A transmission of an internal combustion engine is used in a saddle-type vehicle (buggy) for running on rough terrain. A crankshaft of the vehicle is arranged so that it is parallel with the traveling direction of the body. The transmission includes a mechanism for switching a gear for forward travel and a gear for backward travel. At least a part of the mechanism for switching the gear for forward travel and the gear for backward travel is provided between a crankcase and a crankcase cover. At least one of shafts forming the switching mechanism is partially overlapped with a main shaft or a counter shaft in the axial direction.

Abstract: A transmission system for an electric carrier includes a power source, a speed-reducing gear set, two parallel shafts rotated by the power source, two transmitting members fixed on the two shafts in a vertical condition. A one-way bearing is provided between each transmitting member and the shaft. And a carrier wheel is fixed on an output axle driven by the transmitting members. Clockwise and counterclockwise rotation of the power source with cooperation of the one-way bearings enables the transmitting course change the speed of the electric carrier, lowering the cost and saving energy.

Abstract: A forward/backward steering control mechanism installed in a toy car and coupled to a power drive and controlled by a remote controller to move the toy car forwards/backwards. The forward/backward steering control mechanism uses a remote controller-controlled server to move a movable gear on the transmission shaft of the toy car between a first transmission gear wheel, which is coupled to the power drive of the toy car, and a second transmission gear wheel, which is coupled to the first transmission gear wheel through two meshed idle gears, so as to control the direction of rotation of the transmission shaft, and to further control forward/backward movement of the toy car.

Abstract: A bevel gear forward/reverse mechanism comprises bevel gears, a locking device for forward drive and a band brake for reverse drive. The locking device includes tapered pins mounted to a flanged hub which is slidably mounted on an input shaft of a differential unit and locks the input shaft to the differential unit for forward drive. The differential unit is unlocked when the band brake stops the differential unit from rotating for reverse drive. This mechanism also provides a neutral and a drive shaft brake.

Abstract: A backward driving device for tricycle, especially scooter motorcycle remodelled for the disabled, to be installed to engine power output shaft, incorporated with a shifter for driving backward.

Abstract: A drive apparatus is provided for driving the cutterhead of a forage harvester forward and in reverse. The drive apparatus comprises a hub mounted at one end of a transverse shaft that drives the cutterhead. The hub is connected to and movable along this transverse shaft between a driving position and a non-driving position with respect to another transverse shaft that is connected to a tractor PTO. The cutterhead may be driven forward when the hub is in the driving position and in reverse when the hub is in the non-driving position. A removable belt may be utilized to drive the cutterhead in reverse.

Abstract: A fifth forward speed pinion is mounted by a bearing on the end of a countershaft that provides a space into which the bearing is fitted. A roller bearing mounted in the transmission casing supports the fifth speed pinion at the opposite end from that of the countershaft. The countershaft carries a reverse drive sprocket that is selectively connected to the countershaft by movement of a synchronizer clutch in accordance with control exercised by the vehicle operator. A reverse driven sprocket is drivably connected to the output shaft and torque is transmitted between the sprockets by a flexible, endless chain or belt.

Abstract: Tapper comprising a rotatable tapper main body, a positive rotation transmitting element and a reverse rotation transmitting element disposed in the main body, a holder member disposed in a lower portion of the main body, a driven shaft for holding a tap supported by the holder member and rotatable in positive and reverse directions, and a clutch ring for switching the direction of rotation mounted on the driven shaft. The axial displacement of the driven shaft brings the clutch ring into engagement with the positive rotation transmitting element or the reverse rotation transmitting element selectively to rotate the driven shaft in positive or reverse direction. Each of the clutch and the reverse rotation transmitting element is axially movably supported by a spring for absorbing an axial impact load to be exerted on the driven shaft when the direction of rotation is switched.

Abstract: A power transfer mechanism incorporated in a multiple path drive system includes a transfer case disposed between a source of input torque and at least one drive axle. The transfer case has a pair of parallel drive trains including a gear drive train and a chain drive train, and means for selectively engaging one of the drive trains as desired to provide power transfer. A sprocket in the chain drive train serves as one of the gears in the gear drive train.
