Flexible shaft for car selection and shifting

Abstract

The invention discloses a flexible shaft for selecting and shifting automobiles. The flexible shaft body includes a flexible shaft core wire and a flexible shaft plastic shell, and a flexible shaft nylon lining is arranged between the flexible shaft core wire and the flexible shaft plastic shell. The surface of the flexible shaft plastic shell is wrapped with heat-insulating aluminum platinum. The heat-insulating aluminum platinum is double-layered, and fibers for heat insulation are sandwiched between them. A rubber sheath is arranged between the heat-insulating aluminum platinum and the flexible shaft plastic shell. The heat-insulating aluminum platinum of the invention has a good heat-insulating effect, can prevent the flexible shaft body from being baked and deformed, ensures the normal use of the flexible shaft near the engine exhaust pipe, and enables the vehicle to shift gears normally, making the vehicle run more safely. The rubber sheath plays the role of heat insulation, reducing the heat transfer between the heat-insulating aluminum platinum and the plastic shell of the flexible shaft.

Description

technical field [0001] The invention relates to an automobile flexible shaft, in particular to an automobile flexible shaft for shifting gears. Background technique [0002] At present, the gear selection and shifting of automobiles all use flexible shafts. The flexible shaft includes a flexible shaft core wire for pulling. To protect the flexible shaft core wire, the flexible shaft core wire is wrapped with a flexible shaft plastic shell and a flexible shaft nylon lining. [0003] But the flexible shaft is generally very close to the engine exhaust pipe, such as figure 1 As shown, after the vehicle is started for a period of time, due to the high temperature of the engine exhaust pipe, the flexible shaft is often baked and deformed, resulting in the failure of the vehicle to shift gears normally and affecting the driving safety of the vehicle. Contents of the invention [0004] In view of the above technical problems, the present invention provides a flexible shaft for ...
