Description

Reduce rigidity high pressure fuel pipe structure

Technical Field

The utility model belongs to the technical field of high pressure fuel pipe, more specifically say, in particular to reduce rigidity high pressure fuel pipe structure.

Background

The high-pressure oil pipe for the vehicle mainly appears in a high-pressure injection diesel engine and a high-pressure injection gasoline direct injection engine and can bear the oil pressure required by the engine in the running process; for high pressure oil pipes with less stiffness, the manufacturing tolerances can be moderately relaxed.

Based on the above, due to the fact that the high-pressure oil pipe is different in material, length and axial line shape, the rigidity of the whole shape is different, the pipe fitting with the higher rigidity is difficult to deform, and the tolerance in the installation is poor.

In view of the above, research and improvement are made on the existing structure and defects, and a high-pressure oil pipe structure with reduced rigidity is provided to achieve a more practical purpose.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a reduce rigidity high pressure fuel pipe structure to it is different to cause whole shape rigidity because high pressure fuel pipe material, length and axis shape are different to solve to put forward in the above-mentioned background art, and the great pipe fitting of rigidity warp the difficulty, the poor problem of tolerance nature in the installation.

The utility model relates to a reduce purpose and efficiency of rigidity high pressure fuel pipe structure is reached by following concrete technological means:

a high-pressure oil pipe structure capable of reducing rigidity comprises an oil pump end, a front bend, a rear bend, an oil rail end and a middle bend; the pipeline is of an integral structure, and three bending structures including a front bending structure, a rear bending structure and a middle bending structure are arranged in the whole pipeline.

Furthermore, the front bend and the oil pump end are located at the same vertical position.

Furthermore, the pipeline between the front bending part and the rear bending part is of an inclined structure which is deflected upwards, and a middle bending part is arranged between the front bending part and the rear bending part.

Furthermore, the rear bent rear side and the oil rail end are obliquely arranged.

Compared with the prior art, the utility model discloses following beneficial effect has:

the middle bending is arranged, so that a bending point is added in the middle of the high-pressure oil pipe, the rigidity of the high-pressure oil pipe can be reduced, the fault tolerance of the assembly of the high-pressure oil pipe is improved, the processing difficulty is reduced, and the bending point is particularly applied to the high-pressure oil pipe of the passenger car engine with a compact structure.
