Embodiment Construction

[0010] The present invention will be further described below in conjunction with accompanying drawing:

[0011] exist figure 1 Among them, the journal of the driving shaft 1 is connected with the inner ring of the rolling bearing 2, and is fastened by the retaining ring 13 for the shaft. One end of the guide shaft pin 10 stretches into the inner cavity of the driving shaft 1, and the pin seat is connected with the driving shaft 1; the other end is connected with the inner ring of the miniature bearing 8. The driving shaft 1 is connected with the transmission part of the engine output. When the engine is running, the driving shaft 1 and the guide shaft pin 10 rotate synchronously with the engine, and the two constitute the driving body.

[0012] One end of the driven sleeve 3 is connected with the outer ring of the rolling bearing 2 and fastened by a retaining ring 14 for the hole; the other end is connected with the hollow end cover 7 by threads. The hollow end cover 7 is th...

Abstract

This invention relates to a clutch of a cooling fan in a diesel, in which, TiNi shaped memory alloy is excellent in shape memory, super spring and high damp, this invention utilizes the special performance of said material to manufacture temperature sensed drive elements in a mechanical structure composed of an active part, a slave part, a drive part, a driving element and cooling fans, the driving elements matches with the release spring to act on the taper roller at the same time, which can move in the included angle formed by a taper R-guide way groove of the slave jacket and the taper face of the end of the active shaft to combine or separate the active and the slave bodies.

Description

technical field [0001] The invention is an internal combustion engine accessory, in particular to a mechanical internal combustion engine cooling fan clutch. Background technique [0002] The cooling fan of the car engine is designed according to the worst operating conditions that the machine can encounter. It consumes about 5% of the engine's rated power under rated conditions. At present, the cooling fans of most automobiles are directly driven by the engine. The fan rotates with the engine. Therefore, the cooling fan is operated under non-design working conditions (for example: when the ambient temperature is 10°C-20°C, more than 95% of the time can work without the fan). Inevitably prolonging the engine warm-up time leads to cold wear and waste of fuel. This waste accounts for about 5% of a car's fuel consumption. Therefore, the application of fan clutches in automobiles is one of the four internationally recognized fuel-saving measures. [0003] There are many ty...
