Description
Technical field
The utility model relates to a kind of sink for driving-shaft assembly and with the driving-shaft assembly of sink.
Background technique
In car transmissions, truck drive shaft has the slip yoke of one end and gear-box to pass through spline joint at present, and transmission axle head is internal spline, gear-box end is external splines, gear in male splined shaft connection teeth roller box, fixedly two of male splined shaft bearings can produce heat when long-term running, cause whole gear-box temperature to rise, although temperature can be very not high, can affect the lubricant oil in bearing yet, this lubricant oil Yin Wendu rises and melts, run off in advance, affect the working life of bearing.
Model utility content
The problems referred to above that exist in order to solve prior art, the utility model provides a kind of sink for driving-shaft assembly and with the driving-shaft assembly of sink, object is to prevent that the heat because bearing rotary produces from rise whole gear housing temperature, cause the lubricant oil at bearing place to run off, and then shorten bearing life.
To achieve these goals, the utility model adopts following technological scheme:
A sink for driving-shaft assembly, is characterized in that, has housing, and this housing possesses:
The first opening and the second opening, it is located at respectively the relative both sides of this housing, for passing slip fork shaft;
At least one exhaust outlet, it is located at nearly the first opening side of this housing;
At least one air intake device, it is located at this housing periphery, and this air intake device has an intake grill and a fan sheet, and this fan sheet is located at intake grill side, and when driving-shaft assembly rotates, this fan sheet blows into the wind of surrounding environment in housing.
Further: this housing is column.
Further: this exhaust outlet is two, it is divided into housing the first opening end opposite side.
Further: the square groove of this intake grill for radially running through, groove one side is provided with square fan sheet, and fan sheet is towards transmission shaft sense of rotation.
Further: this air intake device is four, this air intake device circumferential arrangement is in housing periphery.
A driving-shaft assembly with sink, has slip yoke, and this slip yoke contains slip fork shaft, it is characterized in that, wears as above arbitrary described sink for driving-shaft assembly on slip fork shaft.
Compared to existing technology, the utlity model has following advantage: on automobile, install this with after assembly after the transmission shaft of sink, the bulk temperature of gear-box is well controlled, and the bearing on gear-box is also improved working life greatly, and customers' responsiveness using effect is very good.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Embodiment one: as shown in Fig. 1～4, a kind of sink for driving-shaft assembly, there is cylindrical shell 1, this housing 1 possesses the first opening 11 and the second opening that is poroid, it is located at respectively the relative both sides of housing 1 (two ends of cylindrical shell), and the effect of first, second opening is that sink is located on the slip fork shaft of driving-shaft assembly.
The opposite side of housing the first opening end is arranged with an exhaust outlet 3, and exhaust outlet 3 has square hole section and circular hole portion.
Embodiment two: as shown in Figure 5, a kind of driving-shaft assembly with sink, has interconnective transmission shaft 6 and slip yoke 4, and this slip yoke contains slip fork shaft, wears the sink for driving-shaft assembly as described in embodiment one on slip fork shaft.
Next, set forth sink: housing is cylindrical, housing four grooves (intake grill) of inner chamber opens outward 10mm * 34mm, a face of groove still remains attached on housing, like this on the excircle of housing, form four rectangle flabellums, flabellum becomes the angle of 10 degree with the center line a of cylindrical shell.At close stationary housing, that opens two relative sulculuses (circular hole portion) diameter 10mm, opening slot (square hole groove) width 8mm, sulculus and opening slot form exhaust outlet. because four flabellums of housing, area is less, when running, wind-force is little, and the direction of wind can not be controlled, can not well play the effect of cooling, but when the wind-force of four flabellums gathers together, from exhaust outlet out time, wind-force is just large, the wind being gathered together by four flabellums from exhaust outlet out, the direction of wind has been fixed like this, wind-force is also large, can well play the effect of radiating and cooling, when housing is fixed on slip yoke, transmission shaft running, housing is and then running also, the flabellum of housing just plays the effect of fan.When rotating speed is faster, wind-force is larger.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
