Description
Technical field
The utility model is related to a kind of steering oil pipe, more particularly to a kind of commercial car steering oil pipe, it is particularly applicable to increasing
Plus stroke is with the basis of improving radiating effect, by heat abstractor further to improve radiating effect.
Background technology
Traditional commercial car steering oil pipe is mainly made up of steel pipe, and steering oil is after turning to machine heating, and oil temperature is high.Start
Machine steering pump is closer to the distance from the machine of steering, and heat dispersion is very poor, causes to turn to insufficient, the too high steering oil temperature of oil temperature radiating
The aging of steering sealing gasket can be accelerated, decline sealing gasket sealing property, the steering behaviour of steering is reduced.
Authorization Notice No. is CN203186406U, and authorized announcement date is that in September, 2013 utility model patent of 11 days is disclosed
A kind of steering oil pipe with radiator, it include respectively with turn to two sections of oil return hoses that oil can and steering gear are connected, and
The oil return hard tube of two sections of oil return hoses is connected, its oil return hard tube uses U-shaped radiating aluminum pipe, while being equipped with similar radiator on aluminum pipe
The radiator of piece, by radiator by heat in pipeline, is delivered in air as far as possible.Although the design can pass through radiator
Radiating effect is improved, but it still has following defect：
First, the oil return hard tube in the design uses u-tube structure, and stroke is shorter, is unfavorable for radiating；
Secondly, the heat abstractor in the design is one time punching molded aluminum slice, is the entirety that multiple thin slices are constituted, one
Denier wherein has a damage, must replace whole heat abstractor, later maintenance cost is larger；
Again, the combination of the aluminum slice in the design and oil return hard tube is suit, and the firmness of connection is poor, together
When, aluminum slice itself lacks the effect of enhancing connection, and overall connectivity robustness is weaker.
The content of the invention
