Background technique
Existing vehicular planetary gear type differential mechanism is little because of the medium speed difference of going, and it is not serious to wear and tear, and problem is not outstanding; The general window that supplies the lubricant oil turnover that on housing, has; The axle journal place adds Thurst washer between differential gear and differential casing, adds spherical pad between planetary pinion and differential casing, mills out a plane on the planet pin to guarantee lubricating between the axle journal; Or differential gear, planetary pinion between cog are drilled with oilhole; Then lined between differential gear and differential casing in the technological scheme that has, perhaps planet pin is carried out simple thermal treatment, though raising is arranged; But also can't solve the gasoline through freewheeling of automobile device is placed the high slip wearing and tearing aggravation problem that produces on differential mechanism end to the driving wheel spindle nose, do not find the high slip planetary gear type of automobile differential mechanism so far as yet.When behind configuration coast device on differential mechanism end to the driving wheel spindle nose; Under the coast operating mode; Speed discrepancy increases tens times between planetary pinion and planet pin, side gear shaft and differential casing; Wearing and tearing aggravations, planetary gear type differential mechanism are gone and must be changed after three to 50,000 kilometers, cause that the automobile user cost increases, automobile reliability reduces.
Summary of the invention
The objective of the invention is to take comprehensive high abrasion technological scheme, a kind of planetary gear type differential mechanism that can adapt to high slip operating mode fully is provided.Be applicable to the automobile of the various power that installed the coast device additional, realize that automobile inertial utilizes best resultsization.The automobile of this case is meant all Motor Vehicle, comprises electric vehicle, new-energy automobile, except the vehicle of indifferential device.
Technological scheme of the present invention is:
On the axle journal of side gear shaft, planet pin, be respectively equipped with oil leab to improve the lubricating condition at two axle journal places; Adopt the high abrasion thrust washer between differential gear and differential casing and between planetary pinion and differential casing, high abrasion thrust washer material can be stainless steel pile-up welding hard alloy or tungsten-cobalt hard alloy or Steel Bond Hard Alloy or Furtulon or silicon nitride or tin-phosphor bronze or brass or red copper.
Oil leab also can be located on the differential casing that cooperates with the axle journal of side gear shaft, planet pin, the planetary pinion.
Differential gear, planetary pinion are adopted high alloy tool steel or high speed steel or import Wear Resisting Steel or low-carbon alloy steel for carburizing or carbonitrided steel or high wear-resisting cold process instrument Pinion Steel or special purpose vehicle gear alloyed steel, can be 20CrNi3 or 18Cr2Ni4WA or 30CrMnTi or 38CrMoAlA or 22CrMoH or 35CrMo or 42CrMoA or 30CrMoSiA or 17CrNiMo6,20CrNi2Mo or 25CrMoS4H or 34CrMoS4H or DC11 or SCM822H and high-carbon high-high-vanadium high-speed steel.
The heat treatment that side gear shaft, planet pin adopt can be that energetic ion carburized tungsten is handled or the compound carbonizing silicon cladding is handled or TD handles or boronising.
Or the diaxon surface adds batch coating, can be titanium carbide or titanium nitride.
Axle journal place between side gear shaft and its differential casing can be equipped with the anti-wear sleeve or the oil-impregnated bearing of oil leab, and anti-wear sleeve or oil-impregnated bearing adopt stationary fit with between differential casing.
Also can between planetary pinion and planetary pinion shaft neck, add anti-wear sleeve or oil-impregnated bearing.
When installing the automobile inertial utilized device additional on differential mechanism end to the driving wheel spindle nose, differential mechanism is independently installed, with two bearings bevel housing the seat hole in.
When differential casing need be arranged stiffening rib, can on a side body, establish the containing counterbore cover that extends to the opposite side housing, coat opposite side housing and interference fit with it, two side bodies are abutted against and touch the face location, lean on to contain the counterbore cover and feel relieved.Two side bodies set up stiffening rib outward separately, improve the differential casing bulk strength.
Further describe detailed technology content of the present invention and embodiment below in conjunction with accompanying drawing, embodiment described here is just schematic, and is not to be the restriction to All aspects of of the present invention.Only otherwise break away from the protection domain that essence of the present invention and claims propose, the then various distortion of relevant parts and/or reconfigure all row among the present invention in the present invention.Identical reference mark is represented same or analogous parts in the accompanying drawing.
