Automobile gear shifting flexible shaft with high heat insulation performance

Abstract

The invention discloses an automobile gear shifting flexible shaft with high heat insulation performance, and particularly relates to the technical field of flexible shafts. The automobile gear shifting flexible shaft comprises a steel wire flexible shaft main body, a hose, a first shaft base and a second shaft base; a heat insulation mechanism is arranged at the outer end of the steel wire flexible shaft main body; the heat insulation mechanism comprises a first heat insulation sleeve; a second heat insulation sleeve is arranged on one side of the first heat insulation sleeve; first heat-resistant resin is arranged at the outer end of the first heat insulation sleeve; a vertical pipe is fixedly arranged at the top end in the first heat insulation sleeve; a one-way valve is fixedly arranged at the outer end of the first heat insulation sleeve; an air collecting box is fixedly arranged on one side of the top of the second ceramic coating; and a fan is fixedly arranged at the top end inthe air collecting box. The first heat insulation sleeve and the second heat insulation sleeve are installed at the outer end of the hose, and an exhaust fan is used for exhausting air in the first heat insulation sleeve and the second heat insulation sleeve to isolate heat transfer, so that the heat insulation effect can be improved, the hose at the outer end of the steel wire flexible shaft bodycan be prevented from being baked to deform, and normal gear shifting of a vehicle is guaranteed.

Description

technical field [0001] The embodiment of the invention relates to the technical field of flexible shafts, in particular to a flexible shaft for shifting gears of automobiles with high heat insulation performance. Background technique [0002] The flexible shaft is mainly used for the transmission where the axes of the two transmission machines are not on the same straight line, or where relative movement is required during work. It can bend around various obstacles and transmit rotary motion over long distances. It is suitable for occasions subject to continuous vibration to ease the impact, and also suitable for occasions with high speed and small torque. There are three kinds of flexible shafts: steel wire winding type, coupling and wire spring type. In the automotive field, the shaft of the car engine transmits power to the gearbox, and the transmission ratio from the output shaft of the gearbox to the wheels is constant. A "flexible shaft" is installed on the output s...

Problems solved by technology

[0004] To this end, the embodiment of the present invention provides a flexible shaft for automobile shifting with high heat insulation performance, by installing the first heat insulation sleeve and the second heat insulation sleeve on the outer end of the hose and using the exhaust fan to extract the first heat insulation sleeve The air inside the sleeve and the second heat insulation sleeve is used to insulate the heat transfer, so as to improve the heat insulation effect, thereby preventing the hose at the outer end of the flexible wire shaft body from being baked and deformed, and ensuring that the vehicle can shift gears normally. The problem affecting the normal use of the vehicle due to the deformation of the flexible shaft
