Abstract
The utility model relates to an insulating soft shaft. The insulating soft shaft is characterized in that an internal aluminium foil tube and an external aluminium foil tube are sleeved on a straight wire tube of the soft shaft; an insulating material is arranged between the internal aluminium foil tube and the external aluminium foil tube; a fixed cover of an insulating tube is respectively arranged at the two ends of the external aluminium foil tube; and a support spring ring is wound on the insulating material between the insulating material and the external aluminium foil tube. The insulating soft shaft has low thermal conductivity, low thermal capacity, good insulating performance, good chemical stability, corrosion resistance, good electric insulating property, better elasticity and flexibility, convenient processing and installation, good thermal stability and good thermal shock resistance; and the operating temperature can be 800 DEG C to 1350 DEG C.
Description
Technical field
The utility model relates to a kind of heat insulation flexible axle.
Background technique
Unexpectedly strive under the very fierce situation in current various countries automotive industry, the soft manipulation of shorter and shorter employing of cycle that each automobile factory's vehicle updates can well be satisfied these harsh day by day requirements.The flexibility of flexible axle self can be avoided interfering its arrangement convenience in addition with other system in layout effectively, needs the part of design few, and the generalization of manufacturing, seriation, highly specialized, distortion are very easily convenient
But in the process of flexible axle layout, will pass through near the high-temperature part (as turbosupercharger) sometimes, cause the material melts distortion of the crust of flexible axle and internal lining pipe, that cooling back flexible axle can occur is stuck, send out a wrinkle phenomenon lost efficacy flexible axle.So the appearance of heat insulating tube has solved this problem, no longer allow Automobile Design teacher for how getting around the high-temperature part headache.The outer one deck aluminium foil of old in the past process using and inner one deck asbestos paper are locked at the heat insulation method on the flexible axle.Its shortcoming is as follows: 1, water-proof performance is low, and after being drenched by water, asbestos paper lost efficacy, and lost effect of heat insulation.2, the no strong point in the aluminium foil, in transportation or assembly process, after aluminium foil was extruded, thermal conductivity increased, and effect of heat insulation reduces.3, after the locking of aluminium foil two ends, air can't circulate, poor radiation.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of have elasticity and pliability preferably, is convenient to the effective flexible axle of heat insulation and dissipation of installation and processing.
The utility model adopts following technological scheme:
In the utility model is set with on flexible axle raw silk rings pipe the aluminium foil pipe and outside the aluminium foil pipe, between inside and outside aluminium foil pipe, be provided with thermal-protective material, aluminium foil pipe two ends are provided with the heat insulating tube fixed cover outside, thermal-protective material and outside the supported spring circle is arranged around the home on the thermal-protective material between the aluminium foil pipe.
The utility model heat insulating tube fixed cover is provided with radiation hole.
The utility model good effect is as follows: the utlity model has low heat conductivity, low heat capacity, excellent heat insulation property and good chemical stability, anti-erosion, electrical insulating property is good, has elasticity and pliability preferably, be convenient to installation and processing, the utlity model has good thermostability, thermal shock resistance, serviceability temperature can reach: 800 ℃～1350 ℃.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model left view;
Accompanying drawing 3 is the A portion enlarged view of the utility model accompanying drawing 1.
In the accompanying drawings: aluminium foil pipe, 5 thermal-protective materials, 6 flexible axle raw silk rings pipes, 7 radiation holes in 1 heat insulating tube fixed cover, 2 supported spring circles, the 3 outer aluminium foil pipes, 4.
Embodiment
Shown in accompanying drawing 1,3, in the utility model is set with on flexible axle raw silk rings pipe 6 aluminium foil pipe 4 and outside aluminium foil pipe 3, be provided with thermal-protective material 5 between the inside and outside aluminium foil pipe 4,3, aluminium foil pipe 3 two ends are provided with heat insulating tube fixed cover 1 outside, thermal-protective material 5 and outside supported spring circle 2 is arranged around the home on the thermal-protective material 5 between the aluminium foil pipe 3.
As shown in Figure 1, the utility model adopts aluminium foil pipe 4 in inner one deck, wraps a kind of thermal-protective material 5, and thermal-protective material 5 skins support with supported spring circle 2, and then are contained in the outer aluminium foil pipe 3, adopt two heat insulating tube fixed covers 1 to be fixed on the flexible axle.
The utility model adopts a compound pillar of overfill protection of supported spring circle 2, and the utility model is not damaged by pressure in transportation or assembly process.
As shown in Figure 2, the utility model is provided with 8 radiation holes 7 on the fixed cover 1 of two heat insulating tubes, can take away the part heat by air ventilation in vehicle driving.
Aluminium foil pipe 3,4 had certain reflecting action in the utility model was outer, and the part heat can reflect back.
The utlity model has the triple protection effect of heat insulation, heat radiation and anti-heat, the heat insulation reliability of the utility model is strengthened greatly.
