  • Patent number: 8820188
    Abstract: A park-position mechanism includes a selector mechanism that includes a cam mounted on a selector hub shaft, a park gear mounted on a main shaft and corresponding in position to the cam, a park arm arranged between the cam and the park gear. The park arm has a holed base fit over a stud that rotates and supports the park arm in a crankshaft case. A torsion spring is arranged between the park arm and the crankshaft case with ends attached to the park arm and the crankshaft case respectively. The park arm has a driven section and an engaging section respectively extending from opposite sides of the holed base. The engaging section forms a projection. The driven section forms a hole in which a guide rod is received in an axially movable manner. The guide rod is engaged with the earn and is thus selectively driven by the cam to cause engagement of the projection of the engaging section with the park gear. A resilient member is arranged between the hole and the guide rod.

  • Patent number: 8127731
    Abstract: This invention is to provide a tappet clearance adjusting cover coupled with a secondary air valve. The tappet clearance adjusting cover is disposed on a cylinder head of an engine. The secondary air valve includes a recessed element and a cap which jointly form a receiving space receiving therein a one-way valve. The recessed element is provided with an inlet pipe interposed between the cap and the tappet clearance adjusting cover. By disposing the secondary air valve on the tappet clearance adjusting cover and arranging the inlet pipe between the cap and the tappet clearance adjusting cover, with the one-way valve received in the receiving space of the secondary air valve, heat dissipation can be improved while the one-way valve is protected against premature deterioration and carbon deposition caused by a high-temperature exhaust gas from the cylinder head. Thus, reliability as well as a service life of the one-way valve is effectively increased.

  • Patent number: 8082816
    Abstract: A gear-shifting structure is provided for a vehicle. The vehicle includes a transmission box that contains therein a gear train, a clutch, a switching fork, a gear-shifting hub, and a motor. The motor cooperates with a worm shaft to actuate the clutching operation of the clutch and to cause movement of the gear-shifting hub in order to carry out the gear shifting operation. The motor has a rotary member that drives the worm shaft on which a worm and a cam are mounted. To effect gear shifting, the motor drives the worm shaft to have the cam abut and displace the clutch and at the same time, the worm drives the gear-shifting hub to thus realize the operation of gear shifting.

  • Patent number: 7841254
    Abstract: A gear-shifting safety device is provided for an all-terrain vehicle (ATV), including a gear lever, a gear-shifting hub shaft, a gear-shifting gear set, and a reversing bar. An end of the gear-shifting hub forms a step on which a block is provided. The block and the step form a stop face therebetween. The reversing bar has an end forming a stop section that is positionable on the step and is selectively in abutting engagement with the stop face so that to change to the reversing position, the reversing bar must be first actuated to disengage the stop section thereof from the stop face, allowing the switching fork to move to the reversing position on a position chute of the gear-shifting hub, thereby eliminating the damage of accidentally switching to reversing during the forward movement of the vehicle.
