Abstract

The invention relates to the field of heavy duty car engine accessories, in particular to an engine suspension which comprises a front suspension and a rear suspension, wherein the front suspension comprises a front suspension left bracket assembly, a front suspension rubber supporting assembly and a front suspension right bracket assembly; and the rear suspension comprises a rear suspension left bracket assembly, a rear suspension rubber supporting assembly and a rear suspension right bracket assembly. The engine suspension is novel in structure and ingenious in concept, meets the requirement of 360-degree multidirectional inertial impaction torsional vibration in car running, and makes up the state that the original Steyr motor suspension only bears the torsional vibration in the up-and-down direction and the left-and-right direction. The engine suspension is loaded reasonably, the vibration isolation rate meets the use requirement of domestic heavy duty cars at present, the vibration of the whole car is reduced, the car manipulation comfort is improved, the fatigue strength of a driver is reduced, the reliability of car parts is improved, the early damage of the parts is reduced, and the maintenance cost of the car is lowered.

Description

technical field [0001] The invention relates to the field of heavy-duty vehicle engine accessories, in particular to an engine mount. Background technique [0002] At present, domestic heavy-duty vehicles generally adopt Steyr heavy-duty vehicle engine mounts. Since Steyr heavy-duty vehicle engine mounts are products in the middle of the last century, they have not undergone technical improvement after being introduced into China, and their structures are aging. Domestic loading conditions, road conditions, and loading and use requirements vary greatly. At present, the vibration isolation rate of Steyr engine mounts installed on domestic heavy-duty vehicles can only reach about 45%, which cannot meet the current domestic use requirements of heavy-duty vehicles (required to be >70%). Resonance occurs in the speed range of the vehicle (different degrees of resonance occur at idle speed and high speed), and the vehicle vibrates and makes a lot of noise, which causes ear...
