Embodiment 1

[0037] A kind of high pressure power steering gear rubber hose of the present invention such as figure 1 As shown, the rubber hose of the high-pressure power steering gear is composed of the inner tube rubber layer 1, the fiber thread reinforcement layer 2 and the outer tube rubber layer 3 sequentially from the inside to the outside; in this embodiment, the inner tube rubber layer 1 or the The rubber component weight ratio of the outer tube rubber layer 3 is:

[0038] Chlorosulfonated polyethylene rubber CSM: 100; Magnesium oxide: 15;

[0039] Anti-scorch agent: 0.7; Carbon black 660: 50;

[0040] Paraffin oil: 5; Accelerator DM: 1.5;

[0041] Accelerator TMTD: 0.5.

[0042] The manufacturing process of a kind of high-pressure power steering rubber hose of the present invention is as follows: figure 2 shown, including the following steps:

[0043] a. Weigh the rubber components of the rubber layer of the inner tube or the rubber layer of the outer tube according to the a...

Embodiment 2

[0051] The second embodiment is basically the same as the first embodiment, except that in this embodiment, the weight ratio of the rubber components of the inner tube rubber layer 1 or the outer tube rubber layer 3 is:

[0052] Chlorosulfonated polyethylene rubber CSM: 100; magnesium oxide: 13;

[0053] Anti-scorch agent: 0.5; Carbon black 660: 45;

[0054]Paraffin oil: 3; Accelerator DM: 1;

[0055] Accelerator TMTD: 0.3.

[0056] In the manufacturing process steps of the high pressure power steering hose:

[0057] a. Weigh the rubber components of the rubber layer of the inner tube or the rubber layer of the outer tube according to the above weight ratio, and process them by an internal mixer. In order to prevent the rubber from overheating and scorching, the rubber components are reversely mixed. Mixing, and using a rotor speed of 15RPM, the inlet temperature of the cooling water is controlled below 20°C, and the glue output temperature after mixing is 120°C, so that th...

Embodiment 3

[0061] The third embodiment is basically the same as the first embodiment, except that in this embodiment, the weight ratio of the rubber components of the inner tube rubber layer 1 or the outer tube rubber layer 3 is:

[0062] Chlorosulfonated polyethylene rubber CSM: 100; Magnesium oxide: 18;

[0063] Anti-scorch agent: 1.2; Carbon black 660: 55;

[0064] Paraffin oil: 8; Accelerator DM: 2.5;

[0065] Accelerator TMTD: 0.8.

[0066] In the manufacturing process steps of the high pressure power steering hose:

[0067] a. Weigh the rubber components of the rubber layer of the inner tube or the rubber layer of the outer tube according to the above weight ratio, and process them by an internal mixer. In order to prevent the rubber from overheating and scorching, the rubber components are reversely mixed. Mixing, and using a rotor speed of 20RPM, the inlet temperature of the cooling water is controlled below 20°C, and the glue outlet temperature after mixing is 130°C. Thus fi...

Abstract

The invention relates to the technical filed of automotive part manufacture, in particular to a high-pressure power steering gear rubber tube and a manufacturing process of the high-pressure power steering gear rubber tube. The high-pressure power steering gear rubber tube is formed by sequentially compositing an inner pipe rubber layer, a fiber wire enhancement layer and an outer pipe rubber layer from inside to outside. The main sizing material is chlorosulfonated polyethylene rubber (CSM). Each layer of rubber enables a banburying machine to be manufactured into rubber compounds to be compounded and extruded, two copies of fiber wires are weaved on the outer surface of the inner pipe rubber layer, then a pipe blank is formed by extruding the outer pipe rubber layer and wrapping on the surface of the fiber wire, the pipe blank is sleeved on a pipe die core to be arranged in a steam vulcanization tank for vulcanization, and the rubber pipe is obtained after depoling and level pressure of the pipe blank. The high-pressure power steering gear rubber tube has the advantages of being heat-resisting, oil-resisting, voltage-resisting, age-resisting, good in pulse performance, low in manufacture cost and high in percent of pass, and greatly meeting development requirements of modern automotives.

Description

technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to a rubber hose for a high-pressure power steering gear and a manufacturing process thereof. Background technique [0002] There are four main categories of car structure design, among which the chassis system includes brake system and power steering system. The design of these two systems plays an important role in the safe driving of the car. Automobile steering systems can be divided into two types: mechanical steering systems and power steering systems according to the energy source of the steering. The mechanical steering system relies on the steering force of the driver to manipulate the steering wheel to realize the wheel steering; the power steering system realizes the wheel steering by means of the hydraulic pressure generated by the automobile engine or the driving force of the electric motor under the control of the driver. The system is also called a s...
