With the popularization of automobiles, people have higher and higher requirements on the steering performance of the automobiles. At present, most of hydraulic power-assisted steering systems of automobiles adopt a high-pressure hose and steel tube structure and are connected through a joint.
The structure has obvious exposed defects under the condition of frequent operation of automobile steering, and has the following specific phenomena: when the temperature of hydraulic oil rises suddenly and is more than or equal to 130 ℃, the torque force of an automobile steering wheel is increased, the system loses the steering power-assisted function, and can cause the blade to be blocked in a pump body to cause direction failure and cause hidden danger to the safety performance of an automobile when the temperature is serious; meanwhile, the steering oil pump continuously bears huge load to cause continuous rise of oil temperature, and the steering oil pump and the high-low pressure oil pipes are continuously in a 150 ℃ working environment due to the fact that the length of the steel pipe section is relatively short and the heat dissipation effect is poor, so that the service life of the steering oil pump is greatly shortened. And the steering power-assisted effect is obviously reduced, so that the steering is heavy, and the driving steering portability is influenced.
As shown in fig. 1-2, the present embodiment provides a heat dissipation steering oil tube assembly, which includes a steering oil tube hard tube 1, a heat sink 2, and a steering oil tube flexible tube 3, where the steering oil tube hard tube 1 has a plurality of straight sections 11 and bent sections 12, and every two straight sections 11 are connected by a bent section 12; the at least two straight sections 11 are sleeved with radiating fins 2, and the inner walls of the radiating fins 2 are attached to the outer wall of the steering oil pipe hard tube 1; the steering tube hose 3 is connected to one end of the steering tube rigid tube 1.
This embodiment is through setting to the multistage form of buckling to the oil pipe hard tube 1 that turns to, has increased windward heat radiating area, and 11 covers in the straight section portion that turns to oil pipe hard tube 1 simultaneously are equipped with fin 2, 2 inner walls of fin and the laminating of 1 outer wall of oil pipe hard tube, for turning to the heat dissipation of oil pipe hard tube 1, guarantee the commonality and reduce and maintain the replacement cost to make to turn to oil pipe and have better thermal diffusivity, avoid turning to the difficulty.
Specifically, the steering tube rigid tube 1 provided by the present embodiment has six straight sections 11 and five bent sections 12 to increase the heat dissipation area against the wind better, and in other embodiments, the straight sections 11 and the bent sections 12 may be arranged as needed. Meanwhile, in the present embodiment, the three straight sections 11 are sleeved with the heat dissipation fins 2, and in other embodiments, more heat dissipation fins 2 may be provided to enhance the heat dissipation effect. Meanwhile, on the premise of considering the assembly space and the pipeline fixing space, the lengths of the radiating fins 2 should be distributed as long as possible so as to improve the overall heat radiation performance.
Furthermore, the steering oil pipe hose 3 is connected with the steering oil pipe hard pipe 1 through a buckling joint 4, so that the sealing performance between the connection part of the steering oil pipe hose 3 and the steering oil pipe hard pipe 1 is guaranteed.
Further, the heat sink 2 provided by the present embodiment includes an upper heat dissipating fin 21 and a lower heat dissipating fin 22, where the upper heat dissipating fin 21 and the lower heat dissipating fin 22 are detachably connected, specifically, the upper heat dissipating fin 21 and the lower heat dissipating fin 22 are connected by a bolt 23, and a nut is fastened, so that inner walls of the upper heat dissipating fin 21 and the lower heat dissipating fin 22 are tightly attached to an outer wall of the steering oil pipe rigid tube 1. Meanwhile, when the whole vehicle is in a bad operation condition, the surface of the radiating fin 2 is easy to accumulate too much mud, so that the radiating performance is influenced, the radiating fin 2 is made into a split design, the upper radiating fin 21 and the lower radiating fin 22 are easy to separate, so that the radiating fin 2 is detached, the upper radiating fin 21 and the lower radiating fin 22 are cleaned, and the risk that peripheral parts are soaked due to incomplete vehicle-mounted cleaning and washing is avoided. Meanwhile, the existing steering oil pipe hard pipe can be used, and the radiating fins 3 are additionally arranged subsequently, so that the universality is ensured, and the maintenance and replacement cost is reduced.
Further, the upper heat dissipating fin 21 has an upper semi-curved surface and a plurality of upper fins circumferentially spaced along the upper semi-curved surface, and the distance between two adjacent upper fins is equal. More specifically, the upper fins are substantially the same length, and the upper fins that interfere with fasteners such as bolts 23 and nuts may be appropriately reduced in length, with the upper fins possibly being equal in length without interference.
Similarly, the lower heat dissipating fin 22 has a lower semi-curved surface and a plurality of lower fins circumferentially spaced apart from each other along the lower semi-curved surface, and the distances between two adjacent lower fins are equal. More specifically, the lower fins are substantially the same in length, and the lower fins, which interfere with fasteners such as bolts 23 and nuts, can be appropriately reduced in length, with the possibility of the lower fins being equal in length without interference.
In this embodiment, the upper heat dissipating fins 21 and the lower heat dissipating fins 22 are made of aluminum, which has better heat dissipating performance. The steering oil pipe hard pipe 1 is a steel pipe, and the steering oil pipe hose 3 is a rubber hose.
