Abstract
The utility model provides a bridge case driving cylindrical gear assembly, comprising a bridge case driving cylindrical gear and a bushing; multiple end-face keys are arranged at one end of the bridge case driving cylindrical gear, an inter-axle half axle gear is arranged at the other end of the bridge case driving cylindrical gear, a cylindrical gear is arranged in the middle of the outer side surface of the bridge case driving cylindrical gear, an axial through hole is arranged in the bridge case driving cylindrical gear, and the bushing is in clearance fit with the through hole; the bridge case driving cylindrical gear assembly is characterized in that an arc-shaped oil guide groove is arranged at the edge of the through hole at the end of the bridge case driving cylindrical gear, with the end-face keys, and the two ends of the arc-shaped oil guide groove are communicated with the through hole; according to the bridge case driving cylindrical gear assembly, the quantity of lubrication oil entering an inter-axle differential via the bridge case driving cylindrical gear assembly is increased, the effect of lubricating the inter-axle differential is better played, and parts are prevented from being burned.
Description
Technical field
The utility model relates to a kind of driving gear, relates in particular to initiatively cylindrical gears assembly of a kind of gap bridge case.
Background technique
In the existing automotive engineering, transmission shaft need be connected with interaxial differential through gap bridge case active cylindrical gears assembly, realizes differential drive; Existing gap bridge case initiatively is not set to the oil groove that lubricant oil leads on the cylindrical gears assembly specially, makes that lubricant oil is difficult to flow on the interaxial differential through gap bridge case active cylindrical gears assembly, and this just causes interaxial differential to be burnt to death easily, damages device.
The model utility content
To the problem in the background technique, the utility model provides initiatively cylindrical gears assembly of a kind of gap bridge case, comprise gap bridge case initiatively cylindrical gears and lining; Gap bridge case initiatively cylindrical gears one end is provided with a plurality of straight end-face keys (being used for and transmission shaft engagement transferring power); The gap bridge case initiatively the cylindrical gears the other end be provided with the between centers differential gear (be used for interaxial differential in planetary pinion engagement transferring power); The gap bridge case initiatively is provided with cylindrical gears in cylindrical gears outer side surface middle part; The gap bridge case initiatively is provided with axial hole in the cylindrical gears, and lining cooperates with via clearance; Its improvement is: the gap bridge case initiatively through hole edge of cylindrical gears upper-end surface key place end is provided with the arc oil guide slot, and arc oil guide slot two ends are communicated with through hole.The lubricant oil that the arc oil guide slot is splashed in the time of can rotating parts on the end face of straight end-face key place plays leading role; It is imported in the gap between gap bridge case active cylindrical gears and the lining; Increase the oil mass that gets into the lubricant oil of interaxial differential through gap bridge case active cylindrical gears assembly, interaxial differential is played lubrication.
On the aforementioned schemes basis, in order to improve the lubricants capacity that passes through, the utility model has also been done following improvement: said arc oil guide slot has two, and two arc oil guide slot are symmetrical set vertically.
In order to improve the efficient that lubricant oil passes through from the gap between gap bridge case active cylindrical gears and the lining; The utility model has also been done following improvement; Sleeve outer surface is provided with along the axially extended spiral oil groove of crossing of lining, crosses the oil groove two ends and is communicated with lining two ends end face.
The useful technique effect of the utility model is: can increase through the gap bridge case cylindrical gears assembly oil mass that gets into the lubricant oil of interaxial differential initiatively, interaxial differential is played lubrication effect preferably, prevent that parts from burning to death.

Fig. 2, gap bridge case be the end-face structure schematic representation of cylindrical gears upper-end surface key place end initiatively.
Embodiment
A kind of gap bridge case is the cylindrical gears assembly initiatively, comprises gap bridge case initiatively cylindrical gears 1 and lining 2; Gap bridge case initiatively cylindrical gears 1 one ends is provided with a plurality of straight end-face key 1-1; Gap bridge case initiatively cylindrical gears 1 the other end is provided with between centers differential gear 1-3; The gap bridge case initiatively is provided with cylindrical gears 1-2 in cylindrical gears 1 outer side surface middle part; The gap bridge case initiatively is provided with axial hole in the cylindrical gears 1, and lining 2 cooperates with via clearance; It is characterized in that: the gap bridge case initiatively through hole edge of cylindrical gears 1 upper-end surface key 1-1 place end is provided with arc oil guide slot 2, and arc oil guide slot 2 two ends are communicated with through hole.
After adopting the structure of the utility model; During the parts operation; Because of transmission shaft rotates the lubricant oil that is splashed on gap bridge case active cylindrical gears 1 end face, just under the leading role of arc oil guide slot 2, flow in the gap between gap bridge case active cylindrical gears 1 and the lining 2; And finally flow in the interaxial differential, guarantee that the motion of each parts in the interaxial differential obtains lubricated preferably.
In order to increase the oil mass that arc oil guide slot 3 imports, the utility model has also been done following improvement: said arc oil guide slot 3 has two, and two arc oil guide slot 3 are symmetrical set vertically.
In order to increase the efficient that lubricant oil passes through from the gap between gap bridge case active cylindrical gears 1 and the lining 2; The utility model has also been done following improvement: lining 2 outer surfaces are provided with along the lining 2 axially extended spiral oil grooves 4 of crossing, and cross oil groove 4 two ends and are communicated with lining 2 two ends end faces.
