Abstract

The utility model provides a steering oil pipe with a radiator. The steering oil pipe with the radiator comprises two oil return hoses which are connected with a steering oil pot and a steering gear respectively, and an oil return hard pipe which is connected with the two oil return hoses. The oil return hard pipe is made of a U-shaped heat-dissipating aluminum pipe, meanwhile, the radiator which is similar to a heat-dissipating fin is installed on the aluminum pipe, and heat in a pipeline is transmitted to the air as far as possible through the radiator. Compared with the prior art, the steering oil pipe has the advantages that due to the fact that metal heat transmission is used in the radiator and the heat-dissipating aluminum pipe, the contacting area with the air is increased and the heat-dissipating effect is better, and in addition, due to the fact that the radiator and the oil return hard pipe are both made of aluminum materials, the steering oil pipe with the radiator has the advantages of being capable of lowering the weight of a finished vehicle and enduring corrosion.

Description

A kind of steering oil pipe with radiator

Technical field

The utility model relates to the steering swivel system technical field.

Background technology

Along with popularizing of automobile, people are also more and more higher to the motor turning performance requriements.For hydrostatic steering system, especially in summer or the higher area of temperature, when frequently turning to, the temperature of steering hydraulic oil can continue to raise.Oil liquid temperature raises, and to the corrosion of inner bodies such as power steerig pump and deflector and aging, causes part life to reduce aggravation.Turn to oil pipe in the prior art as shown in Figure 1, it in conjunction with forming, is connected one section steel pipe 3 by flexible pipe and hard tube between the first oil return flexible pipe 1 and the second oil return flexible pipe 2, be the fluid heat radiation.But the weight of steel pipe is heavier, has increased the weight of car load, the corrosion-resistant of steel pipe, and needing increases process of surface treatment, also can cause certain environmental pollution.The air that touches of steel pipe is limited in addition, and therefore the heat that transmits is also limited.

In sum, how reducing the turning to fluid operating temperature, is present those skilled in the art's problem demanding prompt solution.

Summary of the invention

The purpose of this utility model is to propose a kind of steering oil pipe with radiator at the too high problem of steering swivel system fluid operating temperature, strengthens the fluid heat radiation situation of pipeline, thereby reduces the system works temperature.

For reaching above-mentioned order ground, the utility model proposes following technical scheme:

A kind of steering oil pipe with radiator comprises respectively and two sections oil return flexible pipes that turn to oil can be connected with deflector, and the oil return hard tube that connects two sections oil return flexible pipes; It is characterized in that: described oil return hard tube adopts aluminum pipe, and at aluminum pipe radiator is installed.

Described radiator adopts the radiator of aluminium matter flake structure.

Described oil return hard tube is U-shaped heat radiation aluminum pipe.

The utility model increases by one section U-shaped heat radiation aluminum pipe in the middle of existing oil return hose line, the radiator of similar radiator fin is housed on the aluminum pipe simultaneously,, is delivered in the air as much as possible heat in the pipeline by radiator.Therefore compared with prior art, radiator is installed in the outside face of oil return hard tube, utilizes the heat transmission of metal, strengthened the area of contact with air, as much as possible heat is delivered in the air; In addition, radiator and oil return hard tube all adopt aluminum material, have reduced the weight of a part of car load, and good corrosion resistance.

The utility model pipeline and radiator processing technology are simple, realize easily, and assembling are simple, and production efficiency is higher, the stock utilization height, and dissipating area is big, can be good at realizing the demand of oil pipe.

Description of drawings

The scheme drawing of the structure of the plain tubing of Fig. 1 prior art;

Fig. 2 structural representation of the present utility model;

The structural representation of Fig. 3 radiator.

The specific embodiment

With reference to Fig. 2, the steering oil pipe after the improvement comprises the first oil return flexible pipe 1, the second oil return flexible pipe 2, connects oil return hard tube 4 and the radiator 5 of two sections oil return flexible pipes.The first oil return flexible pipe, 1 one ends link to each other with turning to oil can, and an end and oil return hard tube 4 are by anulated connection, and the second oil return flexible pipe, 2 one ends link to each other with deflector, and an end and oil return hard tube 4 are by anulated connection.Oil return hard tube 4 adopts U-shaped heat radiation aluminum pipe, and at aluminum pipe radiator 5 is installed.

In conjunction with Fig. 3 as seen, radiator 5 adopts the disposable punch forming of aluminum slice, and after 4 assemblings of oil return hard tube, two ends spot welding gets final product, and its volume that takes up room is little, and dissipating area is big, and the shape of radiator is arranged according to the space and adjusted easy realization.

During work, hydraulic oil flows out from the oil outlet of deflector, enters successively in the second oil return flexible pipe 2, oil return hard tube 4, the first oil return flexible pipe 1, enters then and turns to oil can.It is local preferably that pipeline is assemblied in air flow property as far as possible, and when fluid was flowed through oil return hard tube 4, heat passed to radiator 5 by oil return hard tube 4, and heat is better passed, and played the purpose that reduces the system oil liquid temp.

Claims (3)

1. steering oil pipe with radiator comprises respectively and two sections oil return flexible pipes that turn to oil can be connected with deflector, and the oil return hard tube that connects two sections oil return flexible pipes; It is characterized in that: described oil return hard tube adopts aluminum pipe, and at aluminum pipe radiator is installed.

2. the steering oil pipe of band radiator according to claim 1 is characterized in that: the radiator of described radiator employing aluminium matter flake structure.
