  • CONSTANT SPEED CONTROL METHOD FOR VEHICLE AND DEVICE THEREOF
    Publication number: 20110130930
    Abstract: A constant speed control method for a vehicle and a device thereof are disclosed. The constant speed control method includes steps of: firstly examining if a constant speed switch of the vehicle is pressed by an electronic control unit; allowing the electronic control unit to enter a constant speed mode when the constant speed switch is pressed; and sending a signal by the electronic control unit, so as to lock a throttle locking device for maintaining an opening degree of a throttle valve, and to adjust an transmission ratio of an electric continuously variable transmission (ECVT) for maintaining the constant speed driving of the vehicle. The present invention is further related to a constant speed control device for implementing the above method.

  • All-terrain vehicle gear-shifting safety device
    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.

  • Vehicle shifting mechanism
    Patent number: 7779977
    Abstract: A vehicle shifting mechanism configured for actuation of a clutch and gear-shifting of a shift drum in a transmission is disclosed, which includes a camshaft linked to the shift drum; an actuating motor for driving the camshaft to allow the camshaft to make one revolution to shift the shift drum with one gear; and a cam connected to the camshaft to coaxially rotate with the camshaft and abutting against a release bearing actuating element to actuate engagement and disengagement of the clutch. The cam has a symmetrical contour such that the camshaft driven by the actuating motor is capable of making one unidirectional revolution to enable actuation of the clutch and the gear-shifting of the shift drum to occur concurrently.

  • HANDLE-MOUNTED PARKING BRAKE DEVICE FOR AN ENGINE-POWERED WHEELED VEHICLE
    Publication number: 20100210417
    Abstract: A handle-mounted parking brake device includes a parking brake lever movable between a first position, where a brake unit is disposed at a non-braking position for permitting rotation of a wheel axle of a vehicle, and a second position, where the brake unit is disposed at a braking position, and a cutoff switch having a mechanical switch body displaceable with movement of the parking brake lever between switch-on and switch-off positions, where a condenser discharge ignition is powered by and cut off from a DC power supply, respectively. Premature activation of a starter motor can be avoided to ensure cutoff of an engine when the vehicle is in a parking brake state so as to reliably prevent inadvertent operation to drive the vehicle.
