This utility model discloses a motorcycle electronic
fuel injection throttle structure, including a
throttle body, a
throttle valve plate, and a return
assembly. An
idle speed adjustment
assembly is located on one side of the throttle body. The throttle valve plate is rotatably connected to the throttle body via a throttle valve shaft. The return
assembly is located on one side of the throttle body and includes a return
torsion spring and an auxiliary
torsion spring. One end of the return
torsion spring is sleeved on the throttle valve shaft. Through the linkage design of the return torsion spring and the auxiliary torsion spring, at a small
throttle opening, the two torsion springs together provide sufficient elasticity, reducing
idle speed vibration and improving
idle speed stability. At a large
throttle opening, the auxiliary torsion spring shares part of the elasticity of the return torsion spring, reducing the output torque required for the motor to overcome the
spring force. This reduces motor
energy consumption, allowing for more timely and smooth
power output from the engine at high speeds. Furthermore, the load is distributed between the two torsion springs, resulting in lower stress on each individual torsion spring,
lower risk of fatigue fracture, and longer lifespan.
