Abstract

The invention discloses a driving source variable diesel engine cooling fan and a control method thereof. The cooling fan is applied to a diesel engine and comprises a spindle mounted on the diesel engine, wherein a belt pulley, a clutch, a direct-current motor and a retaining baffle are sequentially positioned and mounted on the spindle; a cooling fan body is embedded into the outer wall of the direct-current motor; the two side surfaces of the clutch are in direct transmission connection with the belt pulley and the cooling fan body respectively; and the retaining baffle is fastened to the end, away from the diesel engine, of the spindle in a threaded mode. According to the design of the driving source variable cooling fan, the cooling fan is adjusted according to the operation condition of the diesel engine and the condition of the clutch and is driven by the direct-current motor or the belt pulley, so that power loss of the diesel engine caused by the cooling fan is reduced, and the comprehensive heat efficiency of the diesel engine is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle engines, in particular to a diesel engine cooling fan with a variable driving source and a control method thereof. Background technique [0002] In pursuit of high thermal efficiency of the diesel engine, it is necessary to reduce the power loss caused by various accessories, and the cooling fan is an important power loss item. The traditional mechanical cooling fan has a simple structure and reliable performance, but it cannot adjust the fan speed according to the needs of different working conditions of the engine, and it is prone to insufficient or excessive cooling of the engine, resulting in low fan efficiency and high power consumption. In order to improve the efficiency of the cooling fan and reduce power consumption, in addition to optimizing the fan blade shape, the existing electric drive scheme can separate the fan from the belt drive system, and the fan can be independently controlled....
