Abstract
The invention discloses a cooling system of a fan clutch. The cooling system comprises a driving shaft, wherein a driving disc is fixedly connected onto the driving shaft. The right side of the driving disc is provided with a cover body, and the left side of the driving disc is provided with a shell body. Two oil return channels are symmetrically arranged on the cover body, and the axis of each oil return channel is vertical to the axis of the driving shaft. Two oil return holes are also arranged in the cover body, and each oil return hole and each oil return channel are respectively and correspondingly arranged and are communicated with each other. As the two oil return channels are symmetrically arranged on the cover body, the dynamic unbalance of the clutch is reduced. The axes of the oil return channels are adjusted to be vertical to the axis of the driving shaft, so that a machining technology of the oil return holes of the clutch is greatly simplified, and the machining cost is reduced. The axis size of the driving disc and the cover body is compressed, so that the space volume of the clutch is reduced by about 10 percent, the radial clearance of annular grooves between the driving disc and the shell body as well as the cover body is reduced, and the capacity to transfer torque of the clutch is increased.
Description
Technical field
The present invention relates to the vehicular clutch field, relate in particular to a kind of radiation system of fan clutch.
Background technique
The conventional fan clutch is the device that relies on silicone oil high viscosity characteristic transmitting torque, and is as shown in Figure 1, and through the folding of control valve block 101 with the relative position adjustment solenoid valve of oil inlet hole 102, thereby the control oil inlet quantity is realized the control to rotating speed.It can come adjustment rotation speed of the fan automatically according to temperature signal, thereby motor is worked under suitable temperature, improves the engine operation performance.But there is following shortcoming in conventional clutch: (1) has only a spill port 103 and a drainback passage 104; This can cause clutch in the high speed rotating process, to produce great unbalanced force; Life-span to clutch produces adverse influence, and the sensitivity of oil return simultaneously also is difficult to guarantee that this can cause the used time of clutch disengage process elongated; It is big that power loss becomes, and influences the usability of silicone oil; (2) drainback passage 104 is angled with clutch axis, and structure is loaded down with trivial details; (3) more too fat to move on the structure, driving disc 105 is anterior protruding, and lid 106 front portions are also protruding thereupon, and to obtain enough space mounting valve blocks 101 parts such as grade, this will make clutch volume and weight increase; (4) annular groove 108 radial clearances between driving disc 105 and housing 107, the lid 106 are bigger, are unfavorable for the clutch moment of torque transmission, uprise at the clutches engaged rate of sliding in state, and power loss is serious.

Following constipation closes embodiment's accompanying drawing, and specific embodiments of the invention is done further to detail, so that technological scheme of the present invention is easier to understand, grasp.
Description of drawings
Fig. 1 is the fan clutch sectional view of existing technology;
Fig. 2 is the sectional view of the embodiment of the invention.
Embodiment
Embodiment:
A kind of fan clutch radiation system of present embodiment; As shown in Figure 2, comprise driving shaft 1, driving shaft 1 connects driving disc 2 through bearing fixing; The right side of driving disc 2 is provided with lid 3; The left side is provided with housing 4, is symmetrically arranged with two drainback passages 5 on the lid 3, the axis of each drainback passage 5 all with the axis normal of driving shaft 1; Also be provided with two spill ports 6 on the lid 3, each spill port 6 and drainback passage 5 corresponding setting and connection respectively.Driving disc 2 is provided with valve block 7, and the cavity between lid 3 and the valve block 7 is an accumulator 8, and silicone oil is housed in it, and each drainback passage 5 is communicated with accumulator 8 respectively; Be equipped with annular groove 9 between driving disc 2 and lid 3 and the housing 4, be communicated with through oil inlet hole 10 between annular groove 9 and the accumulator 8, be communicated with through spill port 6 between annular groove 9 and the drainback passage 5.On the outer surface of housing 4 fan is installed.Be respectively equipped with radiating fin 11 on the outer surface of housing 4 and lid 3, prevent that clutch temp is too high, prolong silicone oil service time.Be connected with Electronic Control Assembly 12 through bearing fixing on the driving shaft 1.The radial clearance of annular groove 9 is 0.2mm ~ 0.4mm, is excellent with 0.3mm especially.
