In order to solve the above technical problems, the flange axle construction on Retarder main shaft of the present invention includes ring flange and flange Axle;Flange shaft vertical connection at the center of ring flange;The one end of the flange shaft away from ring flange has and oil scavenge pump The snap-in structure of impeller connection;The ring flange is provided with away from flange shaft side and is connected with the journal collar on Retarder main shaft Annular connecting portion;The annular connecting portion, ring flange and flange shaft are coaxial.

The flange shaft is multidiameter structure, from ring flange one end to away from ring flange one end be respectively the first ladder section and Second-order bench;The radius of the first ladder section is less than the radius of second-order bench;The first ladder section and the second ladder Section is coaxial;The snap-in structure is the transmission groove being located in second-order bench.

The outer circumference surface of the annular connecting portion is provided with the helicitic texture being connected with journal collar.

Described helicitic texture is anti-pitch thread.

The end face of the annular connecting portion and ring flange forms the accommodating chamber for accommodating lubricating oil;The circumference of the ring flange It is uniformly provided with least two through hole;The through hole is more than the radius of flange shaft but less than accommodating chamber to the distance in the ring flange center of circle Radius.

The circumference of the ring flange is uniformly provided with 4 through holes.

Annular connecting portion, ring flange and the flange shaft are integrally formed.

After above structure, the present invention compared with prior art, has advantages below:1st, flange axle construction delays fluid power The main shaft of fast device is connected with oil suction impeller of pump, and flange axle construction and the axiality of main shaft are high, and the rotatory force of main shaft is transmitted To oil suction impeller of pump, so that oil scavenge pump can convey oil incessantly in automobilism to lubricate Retarder part; 2nd, the circumference of ring flange is uniformly provided with through hole, the function of the existing conveying oil of these through holes, also there is easy disassembly flange axle construction Effect, oil transportation is acted on together as one with dismounting, save the procedure of flange shaft;3rd, flange axle construction has the appearance of conveying oil Receive chamber;Oil can be so delivered to the main shaft of Retarder by accommodating chamber, the part that lubrication coordinates with main shaft, extend main shaft Life-span.

Embodiment

Invention is described in more detail with reference to the accompanying drawings and detailed description.

Referring to shown in accompanying drawing 1 to accompanying drawing 4, the flange axle construction on Retarder main shaft of the present invention, it includes ring flange 1 With flange shaft 2;The flange shaft 2 vertical connection at the center of ring flange 1;One end tool of the flange shaft 2 away from ring flange 1 There is the snap-in structure being connected with oil suction impeller of pump;The ring flange 1 away from the side of flange shaft 2 be provided with Retarder main shaft Journal collar 4 connect annular connecting portion 3;The annular connecting portion 3, ring flange 1 and flange shaft 2 are coaxial.

The flange shaft 2 is multidiameter structure, is respectively the first ladder section from ring flange one end to remote ring flange one end 2.1 and second-order bench 2.2;The radius of the first ladder section 2.1 is less than the radius of second-order bench 2.2;First rank Bench 2.1 and second-order bench 2.2 are coaxial;The snap-in structure is the transmission groove 2.3 being located in second-order bench 2.2, this Sample, in one projection engaged with transmission groove 2.3 of local corresponding setting that oil suction impeller of pump and transmission groove 2.3 connect, Just the rotatory force of ring flange 1 can be made to be transferred to fuel pump impeller.Certainly, snap-in structure does not limit to and this one kind in the present embodiment Structure, such as snap-in structure can also be the projection being located in second-order bench 2.2, connect accordingly in oil suction impeller of pump and projection The place connect sets a groove engaged with projection accordingly, can also realize the rotatory force of ring flange 1 being transferred to oil pump Impeller.Such as snap-in structure can also be the spline being located in second-order bench 2.2, connect accordingly in oil suction impeller of pump and spline The corresponding setting in place one connect and spline slot, can also realize the rotatory force of ring flange 1 being transferred to fuel pump impeller.
