Problems solved by technology

The vibration of the engine body is directly transmitted to the vehicle body through the drive axle and transmission shaft. The gear meshing excitation of the drive axle and the acceleration and deceleration torque impact will be directly transmitted to the engine body, which will cause vibration and noise problems of the vehicle body, and will also cause zero Vibration fatigue failure of components
It can be seen that this scheme has the disadvantages of poor reliability and comfort.

Abstract

The invention discloses an engine suspension and front drive axle integrated arrangement structure which comprises an engine suspension system and a front drive axle suspension system, the engine suspension system comprises an engine front suspension, the front drive axle suspension system comprises an axle suspension hanging ring and an elastic bushing, the number of the engine front suspension is two, the two engine front suspensions are installed on the first multifunctional support and the second multifunctional support respectively, the first multifunctional support and the second multifunctional support are both hinged to the drive axle, and the axle suspension lifting ring is installed on the drive axle. By means of the integrated design of the engine suspension and the drive axle suspension, it is avoided that in the first technical scheme, the number of parts is large, the installation space is insufficient, and the weight of the parts is large, and meanwhile, the defects of vibration noise and poor durability and reliability caused by rigid connection of the metal bracket in the second technical scheme are avoided. The structure is suitable for an engine.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an integrated arrangement structure of an engine mount and a front drive axle. Background technique [0002] Generally, off-road vehicles with longitudinally mounted engines and front independent drive axles need to fix the engine and drive axle main reducer to the vehicle frame through the suspension system (including elastic shock absorbers and connecting brackets) respectively. On the one hand, the suspension system needs to support the weight and impact of the engine / drive axle final drive, and on the other hand, it needs to have the function of vibration and noise reduction to isolate or reduce the transmission of vibration, so that the car has good NVH performance. In order to realize the first function, it is necessary to design independent connecting brackets for the respective suspension systems. In order to realize the second function, it is necessary to design indepen...
