Vibration isolation device of oil pressure sensor

Abstract

The invention relates to a vibration isolation device of an oil pressure sensor. The oil pressure sensor (6) is arranged on an oil pressure sensor seat (1); a red copper washer (8) is arranged between the oil pressure sensor seat (1) and the oil pressure sensor (6); a vibration isolator is composed of a rubber vibration isolation ring (2), a supporting sheath (3) and a rubber vibration isolation sheath (4), wherein the rubber vibration isolation ring (2) is arranged outside the rubber vibration isolation sheath (4); the supporting sheath (3) is arranged in the rubber vibration isolation sheath (4); the vibration isolator is connected with an engine by virtue of a bolt (5) and a washer (7); an oil pressure vibration isolator seat (1) is provided with an oil circuit interface (9); a base (11) is arranged at the lower part of the oil pressure vibration isolator seat (1); a reinforcing rib (13) is arranged at the lower part of the base (11); and the oil circuit interface (9) is connected with the base (11) by virtue of a rectangular stand column (10) and the reinforcing rib (13). The vibration isolation device provided by the invention is simple in structure and is convenient to mount and operate, the problem that the failure rate of the oil pressure sensor is high is solved, and the service life of the oil pressure sensor is prolonged.

Description

technical field [0001] The invention belongs to the field of electronic control of diesel engines, and in particular relates to a vibration isolation device for an oil pressure sensor. Background technique [0002] With the application of diesel engine electronic control technology, the oil pressure sensor plays an important role in the diesel engine oil pressure protection function and is responsible for the collection of oil pressure signals. The internal circuit of the oil pressure sensor is relatively complex, and it is installed on the diesel engine. Due to the severe vibration of the high-strength diesel engine, the damage rate of the oil pressure sensor is high and the service life is short. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an oil pressure sensor vibration isolation device, which plays an isolation and attenuation role in the transmission path of the diesel engine vibration to the oil pressu...
