Abstract
The utility model provides a fixing bracket for a high-pressure oil track of a diesel engine, which comprises a bracket body formed through casting. The fixing bracket is characterized in that a bracket installation hole used for fixing the bracket and an oil track installation hole used for fixing an oil track are integrally cast in the bracket body; the axial line of the bracket installation hole is parallel to the longitudinal axial line of the bracket body; the included angle between the axial line of the oil track installation hole and the longitudinal axial line of the bracket body is 10-40 degrees. The fixing bracket provided by the utility model has the advantages of simplicity and reasonability in structural design and convenience in installation and disassembly, enhances the strength of the bracket body by adopting a casting process, and alleviates the influence on the service life of the oil track caused by bracket vibration; the production cost is lowered; according to the fixing bracket provided by the utility model, the occupied space of the bracket and the oil track positioned on the bracket can be sufficiently saved, the integral structure of the bracket is compact, and the parts positioned on the periphery of the bracket can be effectively avoided, so that the normal working of the oil track can be ensured.
Description
Technical field
The utility model relates to a kind of diesel engine high-pressure co-rail system, especially a kind of diesel engine high-pressure oil rail fixed support.
Background technique
Along with the increasingly stringent of Abgasgesetz, on diesel engine, the coupling high pressure co-rail system reaches the preferential selection that higher emission level becomes domestic and international diesel engine manufacturer.Manufacturer's difference due to the high pressure co-rail system of the different of diesel engine body structure and coupling, cause the mounting arrangements of high pressure co-rail system component on diesel engine of all shapes and colors, high pressure oil rail is as the exterior part of motor, its means of fixation is also different along with diesel engine, but each diesel engine manufacturer can arrange its mounting point for the diesel engine characteristics of oneself.
In prior art, high pressure oil rail is according to the difference of its installing space size, and what have is directly installed on the component such as engine cylinder-body or cylinder cap; If limited by space or mounting hole, need to increase the support that oily rail is installed.At present, most of mounting brackets are steel plate punched or weldment, though support can meet, linkage function are installed, and weight is larger, and outward appearance is coarse, and it is also larger to pass to the vibration of high pressure oil rail; The structural design of a lot of oily rail supports causes the vibration of high pressure oil rail to surpass limit value, has greatly shortened the reliable life of high pressure oil rail, and this is the existing deficiency of prior art.
Summary of the invention
Technical problem to be solved in the utility model, be exactly for the existing deficiency of prior art, and provide a kind of diesel engine high-pressure oil rail support bracket fastened technological scheme, this scheme structural design advantages of simple, easy installation and removal can fully be saved support and be taken up room under the prerequisite that fuel rail is fixing, and the support intensity that adopts casting technique to manufacture is high, fixing oily rail is safe and reliable, and the vibration of support transmission oil supply rail is little, thereby the working life of having improved oily rail.
This programme is achieved by the following technical measures: a kind of diesel engine high-pressure oil rail fixed support, the rack body that comprises casting, the characteristics of this programme are: on described rack body, integrally casting is useful on support bracket fastened support mounting hole and for the oily rail mounting hole of fixing oily rail, the axis of described support mounting hole is parallel with the longitudinal axis of described rack body, and the angle between the axis of described oily rail mounting hole and the longitudinal axis of described rack body is 10 °～40 °.
The concrete characteristics of this programme are: being shaped as of described rack body is tabular, and the forward and backward plate face of rack body all is cast with the wedge shape stiffening rib of intercross arrangement.
Angle between the axis of described oily rail mounting hole and the longitudinal axis of rack body is preferably 25 ° of angles.
Described support mounting hole is unthreaded hole.
The internal surface of described oily rail mounting hole is provided with screw thread.
Described support mounting hole site is in two ends and the central authorities of described rack body.
Described oily rail mounting hole site is between adjacent two stands mounting hole.
The beneficial effect of this programme can learn according to the narration to such scheme, and this scheme comprises the rack body of casting, adopt casting technique can not only guarantee the bulk strength of support, and casting efficiency is high, and cost is low, on described rack body, integrally casting is useful on support bracket fastened support mounting hole and for the oily rail mounting hole of fixing oily rail, the axis of described support mounting hole is parallel with the longitudinal axis of described rack body, angle between the axis of described oily rail mounting hole and the longitudinal axis of described rack body is 10 °～40 °, angle between support mounting hole and oily rail mounting hole is preferably 25 ° of angles, in use, can fully save support and support the taking up room of rail that oil, make the overall structure of support compacter, effectively avoid the component of a frame peripheral, guaranteed the normal operation of oily rail, being shaped as of described rack body is tabular, and the forward and backward plate face of rack body all is cast with the wedge shape stiffening rib of intercross arrangement, has improved the intensity of support, can bear violent impact.This programme structural design is simple, and installation and maintenance are convenient, with low cost.As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment.
The plan view that Fig. 2 is Fig. 1.
The left view that Fig. 3 is Fig. 1.
In figure, 1 is the support mounting hole, and 2 is oily rail mounting hole, and 3 is stiffening rib, and 4 is rack body, 5 longitudinal axis that are rack body, 6 axis that are oily rail mounting hole.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, and, in conjunction with its accompanying drawing, this programme is set forth.
By accompanying drawing, can find out, described a kind of diesel engine high-pressure oil rail fixed support of this programme, the rack body 4 that comprises casting, being shaped as of described rack body 4 is tabular, and the forward and backward plate face of rack body 4 all is cast with the wedge shape stiffening rib 3 of intercross arrangement, for increasing the intensity of rack body 4, support is solid and reliable, thereby it is less to pass to the vibrations of guide rail; On described rack body 4, integrally casting is useful on support bracket fastened support mounting hole 1 and, for the oily rail mounting hole 2 of fixing oily rail, support mounting hole 1 is unthreaded hole, and is positioned at two ends and the central authorities of described rack body 4; The internal surface of oil rail mounting hole 2 is provided with screw thread, and between adjacent two stands mounting hole 1.
