Belt Tensioner Affects Brake Operation Patents (Class 192/224.1)
  • Patent number: 11102925
    Abstract: A drive system includes a first transmission, a second transmission and at least one flexible driving member. The first transmission is operably coupled to a first set of wheels to provide drive power to the first set of wheels responsive to engagement of the first transmission. The second transmission is operably coupled to a second set of wheels to provide drive power to the second set of wheels responsive to engagement of the second transmission. The at least one flexible driving member is operably coupled to a remote actuator and a drive shaft of the walk-behind outdoor power equipment device. The at least one flexible member selectively engages one of the first transmission or the second transmission to switch a walk-behind outdoor power equipment device between all wheel drive operation and another drive mode via the remote actuator.

  • Patent number: 10458178
    Abstract: The invention is a motorized gearbox assembly. The motorized gearbox assembly includes a motor that drives an output shaft. The output shaft actuates a window covering by applying torque to a tilt rod of the window covering. The output shaft extends substantially an entire length of the motorized gearbox assembly. It also has a through-channel that extends substantially an entire length of the output shaft, so that the tilt rod can pass entirely through the motorized gearbox assembly. Because of this, the motorized gearbox assembly can be used for retrofitting blinds. In some embodiments, the motorized gearbox assembly has a diametrically polarized magnet driven by the output shaft, and a position encoder that measures the output shaft's position and number of rotations.

  • Patent number: 9868224
    Abstract: A band saw machine with a disk brake device is provided. A lower gravity wheel is provided with a disk which is turned synchronously. The circumferential edge of the disk is provided with a brake seat. A brake wire provided at the bottom of the band saw machine is connected with a brake lever which can be pivoted. The upper end of the brake lever is in contact with a micro switch seat. Thereby, when the brake lever is pressed, the upper end of the brake lever is away from the micro switch seat, such that the band saw machine is cut off the power supply to stop running. The brake wire links the crank of the brake seat. The brake seat brings a brake action to the disk, such that the lower gravity wheel stops running so as to stop the operation of the saw band of the band saw machine. The present invention provides practical effects of emergent stopping and safety.

  • Patent number: 9326446
    Abstract: A clutch assembly attachable to a rotational output shaft of the engine, wherein the clutch assembly is configured to drive at least one implement of a lawn maintenance vehicle is provided. The clutch assembly includes a first pulley fixedly attached to the output shaft, a second pulley independently rotatable relative to the first pulley, and a belt extending between the first and second pulleys and an idler pulley that is movable between an engaged position and a disengaged position. The clutch assembly further includes a third pulley directly connected with the second pulley, wherein rotation of the second pulley is directly transferred to the third pulley, and rotation of the third pulley provides an output rotation of the clutch assembly.
