Mounting method of engine suspension device for four-cylinder diesel engine

Abstract

The invention discloses a mounting method of an engine suspension device for a four-cylinder diesel engine. The mounting method comprises the steps that a connecting screw, a screw shaft sleeve, a lower damping rubber mat and an upper damping rubber mat are sequentially mounted on a diesel engine bracket; the engine suspension device is screwed through a screw head of the connecting screw, wherein in the screwing process, the upper damping rubber mat and the lower damping rubber mat are compressed; screwing is not stopped until the upper damping rubber mat and the lower damping rubber mat after combination are compressed to the height equaling the height of the screw shaft sleeve, in other words, the upper end face of the screw shaft sleeve is flush with the upper end face of the upper damping rubber mat, and mounting is completed. The mounting method is combined with the structure of the engine suspension deice, the reasonable steps are adopted, in this way, the mounting position is accurate, and the mounted engine suspension device have an excellent damping effect.

Description

technical field [0001] The invention relates to a fixed device for a diesel engine in engineering machinery, in particular to an installation method for an engine suspension device for a four-cylinder diesel engine. Background technique [0002] At present, small four-cylinder diesel engines are widely used in industrial vehicles of small construction machinery. Due to the unbalanced second-order reciprocating inertial force of the piston-connecting rod system in the diesel engine, compared with the six-cylinder diesel engine, the vibration of the four-cylinder diesel engine is more severe during operation; based on this, people will apply the vibration damping pad of the four-cylinder diesel engine The structure of the six-cylinder diesel engine is reduced in proportion to achieve the effect of vibration reduction of the four-cylinder diesel engine. For the small four-cylinder diesel engine, there is no supporting vibration-damping suspension device. At present, it is not o...

Problems solved by technology

Due to the unbalanced second-order reciprocating inertial force of the piston-connecting rod system in the diesel engine, compared with the six-cylinder diesel engine, the vibration of the four-cylinder diesel engine is more severe during operation; based on this, people will apply the vibration damping pad of the four-cylinder diesel engine The structure of the six-cylinder diesel engine is reduced in proportion to achieve the effect of vibration reduction of the four-cylinder diesel engine. For the small four-cylinder diesel engine, there is no supporting vibration-damping suspension device. At present, it is not only necessary to design a matching vibration-damping The suspension device also needs to design a reasonable installation method for the suspension device to achieve good vibration reduction effect and rigidity requirements, because if the vibration reduction device is not installed in place and the installation is unreasonable, not only will it not play a good role Vibration reduction effect, but will increase the vibration of the diesel engine
