Abstract
The utility model discloses an oil returning structure arranged on a hydraulic retarder end cover. The oil returning structure comprises an oil returning opening (1) arranged on the wall of an axial hole in a flange disc (3) on the outer side of a sealing ring (4), and an oil conduction channel (2) arranged in the flange disc (3) and with one end communicated with the oil returning opening (1); the other end of the oil conduction channel (2) is communicated with an oil cavity of a hydraulic retarder; the oil returning opening (1) is formed in the bottom end of the wall of the axial hole in the flange disc (3) and the cross section of the oil returning opening (1) is circular or kidney-shaped. The oil returning structure disclosed by the utility model is used for recycling oil leaking from a gap between a shaft and the hole of the flange disc (3) of the hydraulic retarder end cover, so that the oil energy is circularly used and the cost is saved.
Description
Technical field:
The utility model relates to a kind of oil return system for the hydrodynamic retarder on the military products car, especially a kind of oil-returning structure be located on the hydrodynamic retarder end cap.
Background technique:
Hydrodynamic retarder is a kind of for the complemental brake system on automobile, in the hydrodynamic retarder running, needs to consume a large amount of oil, and at present, general hydrodynamic retarder has oil-returning structure, and oil can be recycled.Seal ring is housed for sealing on hydrodynamic retarder end cap flange plate axis hole, generally, because seal ring can not guarantee to seal fully, always have oil from the gap between axle and hole, leaking out, and herein not for the structure of recovered oil, this has just caused oily waste.
The model utility content:
The technical problems to be solved in the utility model is: provide a kind of for reclaiming the oil-returning structure on the hydrodynamic retarder end cap that is located at from the gap leakage oil out between axle on end cap and hole.
For solving the problems of the technologies described above, the utility model adopts a kind of like this oil-returning structure be located on the hydrodynamic retarder end cap: it comprises return opening and the Oil Guide passage that is located in flange plate and an end is communicated with return opening on the flange plate axis hole wall that is located at the seal ring outside, and the other end of described Oil Guide passage is communicated with the oil pocket of hydrodynamic retarder.
After adopting above structure, the utility model compared with prior art, has the following advantages: make oil utilize more fully, save oily use amount, thereby saved cost.
As preferably, described receiving port is located at the bottom of flange plate axis hole wall, and the oil of seepage on whole axis hole wall can reclaim.
As preferably, the cross section of described receiving port is oval, and the area that oil can contact is large, and the oil of recovery is also more.
The accompanying drawing explanation:
Fig. 1 is the schematic top plan view that the utility model is located at the oil-returning structure on the hydrodynamic retarder end cap.
Fig. 2 is the enlarged diagram of flange plate.
Shown in the utility model figure: 1, return opening, 2, the Oil Guide passage, 3, flange plate, 4, seal ring.
Embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the utility model is located at the oil-returning structure on the hydrodynamic retarder end cap, it comprises return opening 1 and the Oil Guide passage 2 that is located in flange plate 3 and an end is communicated with return opening 1 on the flange plate 3 axis hole walls that are located at seal ring 4 outsides, and the other end of described Oil Guide passage 2 is communicated with the oil pocket of hydrodynamic retarder.When hydrodynamic retarder is worked, when the oil in active chamber passes through flange plate 3, oil can be gone out by the gap leakage between flange plate 3 axis and hole, the oil leaked out flows in return opening 1 along hole wall, along Oil Guide passage 2, flow in the oil pocket of hydrodynamic retarder, oil does not cause waste like this, can re-use.
As preferably, described return opening 1 is located at the bottom of flange plate 3 axis hole walls, and the oil of seepage on whole axis hole wall can reclaim.
As preferably, the cross section of described return opening 1 is kidney-shaped, and the area that oil can contact is large, and the oil of recovery is also more.
Claims (3)
1. oil-returning structure be located on the hydrodynamic retarder end cap, it is characterized in that: it comprises the return opening (1) on flange plate (3) the axis hole wall that is located at seal ring (4) outside and is located at the Oil Guide passage (2) that flange plate (3) is interior and an end is communicated with return opening (1), and the other end of described Oil Guide passage (2) is communicated with the oil pocket of hydrodynamic retarder.
2. oil-returning structure according to claim 1, it is characterized in that: described return opening (1) is located at the bottom of flange plate (3) axis hole wall.
