Description
Technical field
The utility model relates to technical field of automobile engine, is specifically related to a kind of high-pressure common rail device.
Background technique
Along with the development of engine technology, high pressure direct injection technology, with its advantage such as low stain, high efficiency, is subject to the favor of more and more motor manufacturer, is widely used in the automobile both at home and abroad such as benz, BMW, Reynolds and Volvo.High-pressure concentrator is made up of parts such as engine control module (ECU), high-pressure common rail, high pressure oil pump, oil sprayers, ECU is by processing sensor feedback signal, control the parameters such as the emitted dose of oil sprayer, time for spraying and jet pressure, ensure that motor is in optimum Working.As the important component part of high-pressure concentrator, high-pressure common rail, while realization distributes high pressure fuel function, also has the effect of balanced each oil nozzle jet pressure.Under actual conditions, high-pressure common rail, except the pressure that high pressure fuel generation is born in inside, also bears the dither that motor brings in outside.Therefore, in the process of design high-pressure common rail, not only to thicken tube wall, also will increase the intensity with motor attachment portion.The connection fixing block that attachment portion in existing high-pressure common rail between connecting tube and attachment post adopts precision casting to be made in conjunction with mach method mostly, and high-pressure common rail will bear the dither that motor brings in the course of the work, be fixedly connected with by fixed block, not only without buffering and the effect of shock insulation, and its volume is large, Heavy Weight, complex process, cost of production is high.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of high-pressure common rail device, the utility model is not only effectively solved conventional high-tension common rail and is connected by the fixed block of casting between attachment post with connecting tube, not only cushion, isolating affection is poor, and volume is large, Heavy Weight, complex process, the problem that cost of production is high.
The utility model is achieved through the following technical solutions:
A kind of high-pressure common rail device, comprise main oil pipe road (8), main oil pipe road (8) two ends are provided with hermetic terminal (6), main oil pipe road (8) body one sidewall is provided with fuel inlet fitting (10), opposing sidewalls is provided with oil injector seat (2), attachment post (1), oil injector seat (2) is communicated with by connecting tube (7) main oil pipe road (8), it is characterized in that: be provided with shock insulation damping device (4) between described connecting tube (7) and attachment post (1).
The further Technological improvement plan of the utility model is:
The shock insulation bumper bracket (41) that described shock insulation damping device (4) is made through sheet metal process for metal sheet, shock insulation bumper bracket (41) one end is connected with attachment post (1), and opposite end is connected with connecting tube (7).
The further Technological improvement plan of the utility model is:
Described shock insulation bumper bracket (41) one end is provided with opening slot (42), all curved concavity in two ends.
The further Technological improvement plan of the utility model is:
Described shock insulation bumper bracket (41) two ends are all fixedly connected with connecting tube (7), attachment post (1) by soldering.
The further Technological improvement plan of the utility model is:
Described main oil pipe road (8) is also provided with pressure transducer joint (9).
The further Technological improvement plan of the utility model is:
Described connecting tube (7) is communicated with main oil pipe road (8) by connecting tube joint (5)
The utility model compared with prior art, there is obvious advantage: the fixed block that traditional precision casting is machined to by the utility model, be replaced by the shock insulation bumper bracket be made up of sheet metal process, shock insulation bumper bracket one end is provided with opening slot, not only further increase the effect of the shock insulation buffering of shock insulation bumper bracket, and the volume of high-pressure common rail, weight, technique and cost of production are all significantly reduced.
Accompanying drawing explanation
