Description
Technical field
The invention belongs to technical field of automobile parts, relate to a kind of vehicle hose.
Background technique
Automobile, as people's means of transportation, is one of main traffic tool.Automobile has many component that are distributed in each orientation of vehicle body, makes, and be arranged on different azimuth because this type component is mostly rigid material, so they are not suitable for directly connecting and carrying out transmission, therefore flexible axle just appears in vehicle body at large.Because the clutch of operating mechanism and automobile is that rigid construction and mounting point are far away, so flexible axle is particularly useful for the operating mechanism of automobile and being connected of automobile clutch.
As everyone knows, driver, as need change the speed of driving a vehicle, just must swing to realize by handling operating handle, and control system has been carried out the reciprocating stroke of both direction, and therefore flexible axle need to carry the active force of both direction, i.e. thrust and pulling force.The quality of flexible axle has directly determined the gearshift performance of automobile.
Flexible axle comprises mandrel and flexible pipe, and flexible pipe parcel mandrel, flexible pipe is the key position of flexible axle.In above-mentioned reciprocating stroke, the wear resistance of flexible pipe and not yielding be to determine one of important key element of flexible axle life-span.
In sum, need to design good, the on-deformable vehicle hose of a kind of wear resistance.
Summary of the invention
The object of the invention is to have the problems referred to above for existing technology, proposed good, the on-deformable vehicle hose of a kind of wear resistance.
Object of the present invention can realize by following technical proposal: a kind of vehicle hose, comprise the crust that is hollow setting and the internal lining pipe that is arranged on outer intracutaneous, between described internal lining pipe and crust, be provided with successively the first flat filament, steel wire floor and the second flat filament, described the first flat filament concentric is arranged on internal lining pipe outer wall and closely wraps up in the shape of a spiral internal lining pipe, described steel wire floor concentric is arranged on the first flat filament outer wall, described steel wire floor is made up of some steel bars that are evenly distributed on the first flat filament outer wall, described the second flat filament concentric arranges and tight in the shape of a spiral wrapped wire layer, described the second flat filament and crust inwall fit tightly, wherein, described internal lining pipe is made up of nylon composite materials, described nylon composite materials is become to be grouped into by following parts by weight: nylon 1311:60-90 part, POM:5-25 part, carbon fiber: 10-30 part, silicone powder: 1-3 part, TPUE: 0.5-10 part, bulking agent: 6-9 part, antioxidant: 0.5-2 part.
Internal lining pipe in vehicle hose of the present invention is made up of nylon composite materials, and nylon composite materials is mainly made up of POM, carbon fiber and some auxiliary agents enhancing nylon 1311.Nylon 1311 has good physical and mechanical properties, and the performances such as its tensile strength, impact strength, flexural strength, the modulus of elasticity in static bending are suitable with nylon 12, and water absorption rate is significantly less than nylon 12; Flexural modulus, impact strength and nylon 11 are suitable. and elongation at break, apparently higher than nylon 11, has good electrical property and thermal characteristics simultaneously, is a kind of model engineering plastic of function admirable.And POM output is large, the high comprehensive performances such as rigidity, intensity, elasticity, fatigue resistance, chemical-resistant, wear resistance.By POM and nylon 1311 blend, prepare the good internal lining pipe of the mechanical property such as high strength, high wear resistance in conjunction with the advantage of two kinds of polymer.
