Abstract

The utility model relates to an overrunning clutch lubricant passage way structure which comprises a shell body, a bearing, a spline, an inner ring, a snap ring, an overrunning clutch and a planet gear. The overrunning clutch lubricant passage way structure further comprises a sealing ring which is arranged between the inner ring and the shell body. A gap exists between the shell body and the bearing. The gap is communicated with an oil hole arranged in the shell body. The overrunning clutch is arranged on the outer side of the inner ring, and the inner side of the inner ring is arranged on the bearing through the spline. An oil pipeline is arranged in the middle of the inner ring. The oil pipeline is communicated with an oil inlet hole arranged in the overrunning clutch. The spline is a non-full tooth spline. An oil pipeline is arranged in an incomplete tooth portion. One end of the oil pipeline is communicated with the oil pipeline of the inner ring, and the other end of the oil pipeline is communicated with the gap. The oil hole is communicated with a hydraulic system of a speed changer. The overrunning clutch lubricant passage way structure is simple in structure and reasonable in design, and reduces the manufacturing difficulty and cost. Efficient lubrication oil quantity can be provided for the overrunning clutch, and therefore the abrasion can be prevented. The normal operation of an automatic speed changer can be ensured, and the failure rate of the overrunning clutch is reduced.

Description

The overrunning clutch lubricant oil road structure
Technical field
The utility model relates to a kind of oil channel structures, particularly relates to a kind of lubricant oil road structure for the automatic gearbox overrunning clutch.
Background technique
In the automatic transmission working procedure, when rotating, voussoir erects and is stuck between the interior fit on anchor ring to (clockwise or counterclockwise) when the overrunning clutch one party, thus the braking rotating part.The larger then braking moment in gap between voussoir and the overrunning clutch inner ring is less, and in order to obtain larger braking moment, design gaps is less usually.When overrunning clutch rotated to other direction, rotating speed was usually very high, and long time running can make serious wear between voussoir and the overrunning clutch inner ring, thereby affected the braking moment of overrunning clutch.In order to reduce the wearing and tearing of overrunning clutch, good lubricating must be provided, and automatic transmission is interior usually all is to adopt the splash lubrication mode to overrunning clutch, and this lubricating system is under high rotating speed and high moment of torsion operating mode, lubricants capacity is not enough, causes easily parts wear and ablation.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, provide a kind of simple in structure, reasonable in design, can make the lubricants capacity that provides satisfy the operating conditions of overrunning clutch, guarantee the novel overrunning clutch lubricant oil road structure of the normal operation of each component of speed changer.
In order to achieve the above object, the technical solution adopted in the utility model is: comprise housing, bearing, spline, inner ring, snap ring, overrunning clutch and planet wheel, it also comprises seal ring, described seal ring is installed between inner ring and the housing, there is the gap between described housing and the bearing, the oilhole that has on gap and the housing is connected, the outside of described inner ring is equipped with overrunning clutch, the inboard is installed on the bearing by spline, have oil duct in the middle of the inner ring, oil duct communicates with oil inlet hole on the overrunning clutch, described spline is non-full-depth tooth spline, and toothless portion) divides and has oil duct, and oil duct one end is connected with oil duct in the inner ring, the oil duct the other end is connected with the gap, and described oilhole is connected with the hydraulic system of speed changer.
The utility model has the advantages that: 1, simple in structure, reasonable in design, reduce manufacture difficulty and cost; 2, can provide overrunning clutch enough lubricants capacities, wear prevention is guaranteed the normal operation of automatic transmission; 3, reduce the overrunning clutch rate of fault, improved the quality of automatic transmission.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model comprises housing 1, bearing 2, spline 11, inner ring 8, snap ring 10, overrunning clutch 7 and planet wheel 6, it also comprises seal ring 3, described seal ring 3 is installed between inner ring 8 and the housing 1, there is gap 5 between described housing 1 and the bearing 2, the oilhole 4 that has on gap 5 and the housing 1 is connected, the outside of described inner ring 8 is equipped with overrunning clutch 7, the inboard is installed on the bearing 2 by spline 11, have oil duct 9 in the middle of the inner ring 8, oil duct 9 communicates with oil inlet hole on the overrunning clutch 7, described spline 11 is non-full-depth tooth spline, and toothless portion) divides and has oil duct, and oil duct one end is connected with oil duct 9 in the inner ring 8, the oil duct the other end is connected with gap 5, and described oilhole 4 is connected with the hydraulic system of speed changer.Described snap ring 10 is installed on the bearing 2, is positioned at the right side of inner ring 8.Described seal ring 3 is lip-type packing.Described seal ring 3 is O-ring seals.
The utility model comprises housing 1, bearing 2, spline 11, inner ring 8, snap ring 10, overrunning clutch 7 and planet wheel 6 etc.It also comprises seal ring 3, seal ring 3 is installed between inner ring 8 and the housing 1, seal ring 3 general employing lip-type packings, also can adopt the O RunddichtringO, the purpose that adopts seal ring is that the lubricant oil that prevents from leading to overrunning clutch leaks when flowing through slit between inner ring 8 and the housing 1, the loss of lubricant oil not only can cause the waste of lubricant oil, and causes the Lubricating Oil pressure drop low, reduces the lubrication effect to overrunning clutch.
Have gap 5 between the utility model housing 1 and the bearing 2, the oilhole 4 that has on gap 5 and the housing 1 is connected; The outside of inner ring 8 is equipped with overrunning clutch 7, inboard is installed on the bearing 2 by spline 11, has oil ducts 9 in the middle of the inner ring 8, and oil duct 9 communicates with oil inlet hole on the overrunning clutch 7; Spline 11 is non-full-depth tooth spline, and toothless portion) divides and has oil duct, and oil duct one end is connected with oil duct 9 in the inner ring 8, and the oil duct the other end is connected with gap 5; Oilhole 4 is connected with the hydraulic system of speed changer.Oil inlet hole on oil duct, oil duct 9 and the overrunning clutch 7 that forms owing to hypodontia in hydraulic system, oilhole 4, gap 5, the spline 11 has formed the lubricating oil path of overrunning clutch.In the lubricating oil path of hydraulic system, by forming oilhole 4 in housing 1 boring, as the entrance of introducing lubricant oil, lubricant oil through in the gap 5 between housing and the part, the spline 11 because the oil duct that hypodontia forms and oil duct 9 provide lubricant oil to overrunning clutch, oil inlet hole design on the overrunning clutch 7 is in the middle of voussoir, the voussoir of energy sufficient lubrication overrunning clutch and the inner ring of overrunning clutch avoid causing parts wear and ablation like this.Snap ring 10 is installed on the bearing 2, is positioned at the right side of inner ring 8, and purpose is to prevent that inner ring 8 from axially moving along spline 11, plays the effect that inner ring 8 is fixed, and can prevent that lubricant oil from leaking on spline 11 right sides simultaneously.
The utility model discloses a kind of overrunning clutch lubricant oil road structure, draw a lubricating oil path in hydraulic system, overrunning clutch is carried out pressure lubrication, changed traditional splash lubrication mode.By the change of lubricating system, can offer more fully lubricants capacity of overrunning clutch, effectively prevent the wearing and tearing of overrunning clutch, reduce the overrunning clutch rate of fault, improve the quality of automatic transmission.
