Abstract: An electrical control belt continuously variable transmission system controls a movable driving half-pulley or movable driven half-pulley initiatively, by changing a driving interval between the movable driving half-pulley and a fixed driving half-pulley or a driven interval between the movable driven half-pulley and a fixed driven half-pulley, respectively, depending on different statuses, in order to adjust a velocity ratio. By manipulating the movable driving half-pulley or the movable driven half-pulley, the system may further form a driving gap between the movable driving half-pulley and a transmission belt or a driven gap between the movable driven half-pulley and the transmission belt, such that the power is cut off. Clamping the movable driving half-pulley or the movable driven half-pulley to the transmission belt may restore the outputting of the power.

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.

Abstract: An electronic control V-belt continuously variable transmission mechanism is applied in a power transmission system having an engine and support shafts for a driving pulley and a driven pulley, characterized by driving the driving pulley with power supplied by a pulley driving system such that a movable portion of the driving pulley moves axially to the driving-pulley support shaft, thereby enabling a movable portion of a driven pulley connected to the driving pulley to move in response to the axial distance variation, thus changing the rotational speed of the driven pulley. The contact between a cam guide groove of a bearing base of the pulley driving system and a cam guide device is transmitted through rolling friction, and the transmission efficiency is increased by a complex lead angle effect formed between a lead angle of the cam guide groove and a lead screw.
