Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1-5, a noise reduction structure for improving noise of an oil pump of an automatic transmission, has:
an oil cooler;
the oil inlet pipe and the oil outlet pipe are communicated with the oil cooler;
the oil outlet pipe expansion cavity is arranged on the oil outlet pipe; the expansion chamber is used to eliminate fluid pulsation excitation.
The connecting bracket can be connected with a front longitudinal beam of the vehicle body;
the rubber vibration damping pad unit is arranged on the connecting bracket; the oil cooler is connected with the connecting bracket through the rubber vibration damping pad unit. By utilizing the vibration isolation characteristic of the rubber cushion, the noise of the oil pump transmitted to the interior of the vehicle through the front longitudinal beam of the vehicle body is effectively blocked from the transmission path.
The oil cooler is also provided with a damping pad fixing bolt which penetrates through the rubber damping pad unit to be connected with the oil cooler and the connecting support. The connecting support is connected with the front longitudinal beam of the vehicle body through the connecting support fixing bolt.
The both sides of linking bridge all are equipped with rubber damping pad unit, and the both sides of oil cooler are connected with the rubber damping pad unit of linking bridge both sides respectively.
Vibration and noise generated in the working process of the oil pump are transmitted to the oil cooler through the oil outlet pipe and are transmitted into the vehicle through the connecting bracket with the front longitudinal beam of the vehicle body. In order to block the transmission of fluid excitation of an oil pump of the transmission to the inside of a vehicle, an oil outlet pipe expansion cavity of the transmission and a rubber vibration damping pad unit are additionally arranged between the transmission and a connecting support of a front longitudinal beam of the vehicle body to form a two-stage vibration damping system, vibration transmitted to the front longitudinal beam of the vehicle body by the oil pump is obviously reduced after vibration isolation of the vibration damping system, and noise of the oil pump in the vehicle is obviously reduced.
Has the following advantages: firstly, eliminating partial pressure pulsation through an expansion cavity of an oil outlet pipeline of a gearbox; after vibration isolation is carried out on the rubber vibration damping pad unit, the vibration of an oil pump at the front longitudinal beam of the vehicle body is obviously reduced; after vibration isolation of the rubber vibration damping pad unit, noise of the oil pump in the automobile is obviously reduced, and driving comfort is obviously improved.
After adopting foretell structure, reduce the structure transmission of oil pump noise to the car, reduce the car in the oil pump noise.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
