However, because the existing water pump is arranged in the middle of the front end of the engine, the cooling range of the radiator and fan is relatively close to the lower end of the whole machine. This arrangement leads to suboptimal cooling performance of the radiator and fan
In order to optimize the cooling performance of the fan, it is necessary to move up the radiator and the height of the fan arrangement, that is, to move up the arrangement height of the water pump, but the upward movement of the water pump will cause interference between the lifting lugs of the whole machine and the water pump, and also affect the air conditioner in the air conditioner. The layout position on the whole machine

The invention discloses a front end structure of an engine. The front end structure comprises an auxiliary installing piece, a water pump and a fan. The lower portion of the auxiliary installing piece is fixedly connected with the upper portion of the front end of an engine body, and the upper portion of the auxiliary installing piece is fixedly connected with a cylinder cover at the front end of the engine. A lifting lug is arranged at the upper end of the auxiliary installing piece, and the cylinder cover of the engine is not provided with the lifting lug. A pump body of the water pump is arranged at the front end of the auxiliary installing piece, and a belt wheel of the water pump is located at the middle portion of the auxiliary installing piece. The fan is arranged at the front end of the belt wheel of the water pump. According to the front end structure, by means of the auxiliary installing piece, the installing height of the water pump is increased to the upper portion of the engine body, namely the upper portion of the whole machine, the installing and arranging heights of the radiator and the fan on the whole machine are increased, a cooling system is closer to the cylinder cover, and the cooling performance of the radiator and the water pump is optimized; and meanwhile the problems of interference between the lifting lug of the whole machine and the water pump and the arrangement of an air conditioner are solved.
Description
technical field [0001] The invention relates to the field of engines, in particular to an engine front end structure. Background technique [0002] The existing non-road engine integrated water pump arrangement is controlled by the cost of the whole machine. The water pump is generally arranged in the middle of the front end of the engine (in the height direction) and fixedly installed on the front end of the body; the front end of the water pump is installed with a driving fan, and the water pump An air conditioner is installed above. The front-end gear train adopts a double-layer gear train arrangement. The first layer of gear train parts includes crankshafts, generators (for some models), water pumps, tensioners, etc.; the second layer of gear train parts includes water pumps, air conditioners, generators (other Some models), etc., the water pump drives the air conditioner or generator. The cooling sequence of the engine cooling system is generally water pump-oil cooler...
