  • Patent number: 9758006
    Abstract: Disclosed herein are a driving unit and a robot cleaner having the same. The robot cleaner has a configuration in which an elastic member is supported so that an angle formed between the elastic member and a rotation shaft of the driving unit is provided in a predetermined range to offset a decrease in an elastic force generated while the robot cleaner is driving on a surface having steps and a driving wheel protrudes downward from the robot cleaner. Accordingly, there is the effect where a traction force is maintained at a predetermined level for maintaining the driving performance of the robot cleaner even while the robot cleaner is driving and the driving wheel is lowered to decrease the elastic force of the elastic member.

  • Patent number: 8479862
    Abstract: A branch joint is provided at the rear portion of an exhaust pipe. Second exhaust pipes with a small diameter arranged one above the other are branched at a position forward of an intersecting position P with a pivot plate. The second exhaust pipes are made to intersect the inside of the pivot plate. The gap between the pivot plate and the engine can be narrowed while ensuring a smooth exhaust. The exhaust path lengths of the second exhaust pipes are made to be offset from each other so as not to be the integral multiple of the wavelength of the exhaust sound in the operating area. This allows exhaust gases to interfere with each other in the muffler. Thus, the exhaust sound can be reduced and the muffler can be downsized. This allows for the slimming of the vehicle body without lowering the output of the engine.

  • Patent number: 5290201
    Abstract: An agricultural combine such as used in the harvesting of crops includes oscillating or fixed forward tandem drive wheels which are coupled to the combine's support frame, or undercarriage, to provide a smooth ride over rough fields and a more uniform crop cutting height above the soil. The combine also includes a body typically housing a diesel engine, operator controls such as in an enclosed cab, a grain and residue separating system, a grain storage bin, and an auger of off-loading the harvested grain. The combine body, which also typically has an array of row crop heads disposed on a forward portion thereof, is disposed on and coupled to the support frame in a slidable manner permitting the body to move forward to distribute the weight primarily over the tandem drive wheels for improved traction for operating in muddy fields and to accommodate larger grain loads.

  • Patent number: 4984663
    Abstract: A rotational force which was input from a transmission is received by a main shaft and transferred to the rear wheel side. The rotational force of the main shaft is transferred to the front wheel side through a hydraulic clutch. The hydraulic clutch receives the supply of an operating hydraulic pressure from an oil pump which is driven by a DC motor. Further, an operating hydraulic pressure is supplied in parallel to the hydraulic clutch from a second oil pump which is driven by the main shaft. The DC motor is driven only in the low-speed mode, stop mode, and reverse mode. On the other hand, after the motor was turned on at a rotational speed of a predetermined rotational speed or less, if the speed does not reach a second rotational speed higher than the predetermined rotational speed, the motor is not turned off.

  • Patent number: 4745825
    Abstract: A transfer gear has high speed and low speed modes with two wheel drive or four wheel drive. A main drive shaft has a main drive gear rotatably mounted on it. A main shaft is coaxial with the main drive shaft and carries a speed change gear rotatably on it and drives the rear wheels. The main shaft further rotatably supports a front drive gear which transfers power to the front wheels. A counter gear assembly provides a speed reduction between the main drive gear and the speed change gear. A first switching mechanism connects the main drive shaft to either the main shaft or the main drive gear. A second switching mechanism connects the main shaft either to the speed change gear or to the front drive gear, or disconnects both the speed change gear and the front drive gear from the main shaft, or connects both the speed change gear and the front drive gear to the main shaft.

  • Patent number: 4714126
    Abstract: A four-wheel drive vehicle having straddle-type seating. A power train is located beneath the seat and between the footpegs of the vehicle, the engine employs parallel output shafts located on either side of the crankshaft to drive power transmission means to the front and rear axles. A speed change mechanism is contained within the engine case along with the output shafts and includes a first transmission shaft between the crankshaft and one of the output shafts. The arrangement of the frame is such that the upper portion of the frame is narrower than the lower portion of the frame for appropriate rider comfort and footpeg location. The wheels are located such that the front and rear tracks are substantially the same and diagonals between the wheel centers cross close to the center of gravity of the vehicle. The cushion assemblies of the vehicle are inclined to increase cushion stroke and the steering assembly is arranged with crossing tie bars for maximum steering control with minimum mechanical complexity.

  • Patent number: 4706770
    Abstract: A utility hauling vehicle includes at least one steerable wheel suspended from the forward end of a rigid frame of the vehicle and front and rear pairs of unsuspended drive wheels mounted to the rigid frame rearwardly of the steerable wheel. The front pair of drive wheels is differentially driven and the rear pair of drive wheels is respectively coupled for being driven in unison with the front pair of drive wheels. A differential lock is provided for locking the rear pair of drive wheels and, hence, the front pair of drive wheels for rotation in unison. The suspension for the steerable front wheel or wheels acts to lift the forward end of the frame to transfer weight to the rear pair of drive wheels. Weight transfer can also be accomplished by mounting the front pair of drive wheels at a level above the rear pair of drive wheels. The vehicle has a load bearing zone substantially within a vertical projection of the largest area occupied by the drive wheels.

  • Patent number: 4560018
    Abstract: A drive mechanism is disclosed for rotating a pair of tandem wheel assemblies journalled on a centrally pivoted tandem drive housing. A jointless elastomeric belt extends about the wheel assemblies which are driven by two chains entrained over respective sprockets contained within the tandem drive housing. A planetary gear set is effective to powerably drive both chains with a differential action to minimize the influence of the belt loading upon the chains. The planetary gear set and the sprockets are constructed to deliver a greater torque to the rear wheel assembly than the front wheel assembly through the chains.
