Abstract

A four-point distribution power assembly suspension device comprises a front suspension device and a rear suspension device, wherein one end of the front suspension device is fixedly connected with an engine shell, the other end of the front suspension device is fixedly connected with a vehicle frame longitudinal beam, one end of the rear suspension device is fixedly connected with a side board of a gearbox shell, and the other end of the rear suspension device is fixedly connected with the vehicle frame longitudinal beam; one end of the rear suspension device is fixedly connected with the middle portion of the side board of the gearbox shell, and the other end of the rear suspension device is fixedly connected with the vehicle frame longitudinal beam; the rear suspension device comprises a suspension bracket, a suspension soft cushion assembly and a suspension bracket, the top of the suspension soft cushion assembly is fixedly connected with the middle portion of the side board of the gearbox shell through the suspension support, and the middle portion of the suspension soft cushion assembly is fixedly connected with the vehicle frame longitudinal beam through the suspension bracket. According to the design, the span distance between the front suspension device and the rear suspension device is increased, vibration isolation performance of a power suspension system is enhanced, whole-vehicle comfort is enhanced, the rear suspension device is not provided with a transverse beam, original assembly space of a vehicle model is not changed, and a suitable range is wide.

Description

technical field [0001] The invention relates to a suspension device of an automobile power system, in particular to a four-point arrangement type power assembly suspension device, which is particularly suitable for increasing the longitudinal span of the front and rear suspensions of the automobile and improving the comfort of the whole vehicle. Background technique [0002] As an important support and vibration isolation element of the powertrain, the engine mount has high requirements for the support and vibration isolation of the engine mount. The existing technology is a four-point mounting method. The engine rear mounting assembly is generally fixed on the engine flywheel housing or the clutch housing. The front and rear mountings have a small longitudinal span of the vehicle and cannot meet the rigidity in a specific direction. and strength requirements, poor vibration isolation performance, and due to more rigid contact, the impact deformation and dynamic deformation ...
