A kind of flexible shaft for automobile shifting with high heat insulation performance

Abstract

The invention discloses a flexible shaft for automobile shifting with high heat insulation performance, specifically relates to the technical field of flexible shafts, comprising a steel wire flexible shaft main body, a hose, a first shaft seat and a second shaft seat, the steel wire flexible shaft The outer end of the main body is provided with a heat insulation mechanism; the heat insulation mechanism includes a first heat insulation sleeve, a second heat insulation sleeve is provided on one side of the first heat insulation sleeve, and a second heat insulation sleeve is provided at the outer end of the first heat insulation sleeve. A heat-resistant resin, a vertical pipe is fixed on the inner top of the first heat-insulation sleeve, a check valve is fixed on the outer end of the first heat-insulation sleeve, and a collection valve is fixed on one side of the top of the second ceramic coating. A bellows, a fan is fixed at the top inside the wind collecting box. The present invention installs the first heat-insulating sleeve and the second heat-insulating sleeve on the outer end of the hose and uses the exhaust fan to extract the air inside the first heat-insulating sleeve and the second heat-insulating sleeve to insulate heat transfer, thereby improving heat insulation As a result, the hose at the outer end of the flexible wire shaft main body can be prevented from being roasted and deformed, so that the vehicle can shift gears normally.

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
