Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] The oil cooling pipe of the automatic transmission of the present invention comprises an inner pipe rubber layer, a fiber thread reinforcement layer and an outer pipe rubber layer from the inside to the outside, and the inner and outer pipe rubber layers include the following components:

[0038] Ethylene / acrylate 100 parts by weight

[0039] 1# vulcanizing agent 3.5 parts by weight

[0040] 1.5 parts by weight of crosslinking agent TAIC

[0041] Antiaging agent 445 1 part by weight

[0042] Reinforcing agent 990 80 parts by weight

[0043] Plasticizer TP759 8 parts by weight

[0044] Internal release agent 18D 1 part by weight

[0045] The fiber thread reinforcement layer is an aramid thread layer. Aramid yarn is selected as yarn because of its high strength, low elongation and good pulse performance.

Abstract

The invention discloses an oil-cooling pipe of an automatic gearbox and production process thereof. The oil-cooling pipe sequentially comprises an inner rubber layer, a fiber-wire strengthening layerand an outer rubber layer from inside to outside. The oil-cooling pipe is manufactured according to the steps of: (1) delivering rubber components of both inner and outer rubber layers to a banburyingmachine for mixing; (2) carrying out rapid detection to the semi-finished rubber material after the banburying process; (3) putting the rubber material into a 90 extrusion machine with straight headto extrude the inner rubber layer out; (4) adopting a 24-spindle vertical braiding machine to weave the fiber-wire strengthening layer on the extruded inner rubber layer; (5) adopting a T-shaped headto extrude the semi-finished product obtained in step (4) on the 90 extrusion machine so as to obtain the outer rubber layer; (6) cutting off the rubber pipe and carrying out vulcanization in a digester; and (7) obtaining the finished products after washing the rubber pipe and cutting pipe heads. The invention simplifies the production process, saves cost and leads the operation to be more convenient; and simultaneously, the binding is stable and the product quality is better.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an oil cooling pipe of an automatic transmission and a production process thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, cars have become one of the means of transportation for people. At present, more and more automobiles adopt automatic transmission structure, so the requirements for automatic transmission and related components are getting higher and higher. The automatic transmission is a combination of a hydraulic transmission transmission and a gear transmission transmission. It is composed of a liquid torque converter, a transmission gearbox, an oil pump, an oil cooling system, a control system, and a transmission device. Among them, the oil cooling system is an indispensable system of the automatic transmission. Its main function is to dissipate the heat generated during the working process of the aut...
