Title: ENGINE SPEED LIMITER, AND VEHICLE
Abstract:
An engine speed limiter, and a vehicle. The engine speed limiter comprises a rotational pull piece and an oil feed restriction piece. The rotational pull piece comprises a rotational shaft (10) and a pulling force generating piece (20). The pulling force generating piece (20) is connected to the rotational shaft (10), and is driven by the rotational shaft (10) to rotate to generate a pulling force. The oil feed restriction piece comprises a cylinder (30) and an oil feed passage provided on the cylinder (30). The cylinder (30) is further provided with an oil limitation passage (31). The oil feed passage is connected to an oil supply pipe of the engine, and the oil limitation passage (31) and the oil feed passage pass across each other. The oil feed restriction piece further comprises a piston (32) movably disposed in the oil limitation passage (31). The piston (32) is connected to the pulling force generating piece (20) for controlling the flow area of the oil feed passage. The engine speed limiter can effectively limit the engine speed, so as to limit the speed of the vehicle.
