Abstract

The invention discloses a pure electric commercial vehicle power assembly suspension system. According to the system, the front end of a power assemble comprising a motor is connected with the middle of a U-shaped-structure front suspension bracket through a front suspension support and a front suspension bolster assembly in sequence; the left end and the right end of the front suspension bracket are connected with a vehicle frame longitudinal beam; the rear end of the power assembly is connected with the vehicle frame longitudinal beam through a rear suspension support and a rear suspension bolster assembly in sequence; the front suspension support, the front suspension bolster assembly and the front suspension bracket are connected with one another in a vertical tightened mode, and the rear suspension support and the rear suspension bolster assembly are also connected in a vertical tightened mode; the front suspension bolster assembly comprises an upper framework, a rubber body and a lower framework; and the upper framework is internally provided with upper grooves, and the lower framework is internally provided with lower protrusion blocks connected with the corresponding upper grooves in a clamped mode. According to the design, the suspension system is suitable for power assemblies where motors are additionally arranged of pure electric commercial vehicles, and good in vibration isolation effect, the assembling difficulty can be lowered, three-direction limiting can be achieved, the weight is low, and the cost is low.

Description

technical field [0001] The present invention relates to a vehicle power assembly mounting system, in particular to a pure electric commercial vehicle power assembly mounting system and an assembly method thereof, and is particularly suitable for improving the performance of the power assembly of a pure electric commercial vehicle with an added motor. vibration isolation effect. Background technique [0002] In the automotive powertrain mounting device, the gearbox mounting system of a commercial vehicle is used as an auxiliary support device for the powertrain and is connected with the gearbox to ensure that the deformation and displacement of the gearbox do not exceed the allowable range during the operation of the vehicle. At the same time, it has a good ability to suppress vibration, but the vibration isolation effect of the existing commercial vehicle powertrain mount is weak. For example, the vibration isolation rate of Steyr type is only about 45%, which cannot meet th...
