Disclosure of Invention
The invention aims to provide a single-stage vibration isolation compressor suspension bracket for side installation of a new energy vehicle, and the vibration generated by an excitation source of the compressor can be effectively attenuated by adding a rubber bushing for shock absorption at each of three bracket mounting points connected with an electric drive system and matching with the connection relation between a rubber main spring and an inner pipe and an outer pipe of the bushing due to certain elasticity of the rubber main spring.
The aim of the invention can be achieved by the following technical scheme:
the single-stage vibration isolation compressor suspension bracket comprises a suspension bracket and three rubber bushings for shock absorption, wherein three supporting seats for installing the rubber bushings are arranged on the suspension bracket, reinforcing ribs are arranged between two adjacent supporting seats, and a plurality of connecting seats for connection are arranged on the suspension bracket;
the rubber bushing comprises a bushing inner pipe matched with the shaft body, a rubber main spring used for damping is arranged on the surface of the bushing inner pipe, a bushing outer pipe is arranged on the surface of the rubber main spring, and an upper limiting gasket is fixedly connected to the top of the bushing inner pipe.
As a further scheme of the invention: the bottom of rubber bush is provided with rubber gasket through the mode of interference pressure equipment to flush with the terminal surface of rubber main spring, rubber gasket is used for spacing and shock attenuation to the axial, be equipped with lower floor's spacing gasket through riveted mode on the terminal surface of bush inner tube.
As a further scheme of the invention: the rubber bushing is pressed into the supporting seat through interference connection, the upper limiting gasket is kept flush with the end face of the supporting seat, and the bushing inner tube, the rubber main spring and the bushing outer tube are assembled together through vulcanization.
The invention has the beneficial effects that: the compressor is connected to the suspension bracket connecting seat of the compressor suspension through the bolt, compares the pure aluminum connecting bracket of the original structure, adds a rubber bushing for shock absorption through each of three bracket mounting points connected with the electric drive system, and because the rubber main spring has certain elasticity, the connection relation between the rubber main spring and the bushing inner tube and the bushing outer tube is matched, the vibration generated by the compressor excitation source can be effectively attenuated, and the NVH comfort can be improved.
