Motorcycle accessories chain tension adjuster

The position where the late closing angle of the intake valve of the engine for motorcycle vehicle accessories decreases in order to increase the maximum torque at low speed. The intake camshaft is driven by the exhaust camshaft through a chain. A variable valve timing regulator is set between the two shafts. Under the action of the internal hydraulic cylinder, the regulator in motorcycle vehicle accessories can rise and fall. When the engine speed drops, the variable valve timing adjuster drops, the upper motorcycle chain is loosened, and the lower motorcycle chain acts on the rotating tension of the exhaust cam and the downward thrust of the adjuster. Because the exhaust camshaft cannot rotate counterclockwise under the action of the crankshaft timing chain, the inlet camshaft is subject to the joint action of two forces: one is the tension of the chain driven by the normal rotation of the exhaust camshaft; The second is the tension that the adjuster pushes the chain and transfers to the exhaust cam. The intake camshaft rotates additionally clockwise θ Angle, which speeds up the closing of the intake valve, i.e. reduces the late closing angle of the intake valve θ Degrees.
