[Patent description] Power steering oil storage tank device
【 Technical field 】
[0001] The invention relates to an automobile power steering system, in particular to a power steering oil storage tank device.
【 Background technique 】
[0002] The main structure of the power steering tank is the assembly of the tank body, filter element, tank cover, oil scale and sealing ring. Its purpose is to provide power oil and oil cooling for the power steering system, and the power system filters the impurities of the system through the oil circulation, so as to ensure that the driver can easily manipulate the steering wheel through the power steering system, reduce driver fatigue and enhance driving comfort.
[0003] The traditional power steering oil tank is mainly composed of a tank body, a filter element arranged in the tank body and a central pipe, and the tank body is provided with an oil inlet and an oil outlet, and the axial end of the tank body is provided with an opening, and the opening is provided with a tank cover that closes the tank body. A sealing ring is arranged between the tank body and the tank cover; The sealing ring is installed between the lid and the tank body through the screw lock, and then the sealing ring is installed between the lid and the tank body. This assembly method requires high precision, and the compression force required by the sealing ring cannot be achieved by manual locking, and its sealing cannot be guaranteed. In the traditional tank, the tank locking mechanism and the oil scale are set relatively independently, that is, the tank locking mechanism and the oil scale need to be set respectively on the tank lid. The processing process is not only complicated, but also the increase of processing steps will increase the production cost, and the assembly process will become complicated.

【 Content of invention 】

[0004] Aiming at the shortcomings of the prior art, the invention provides a power steering storage tank device with good sealing property, low processing cost and convenient assembly.
[0005] In order to realize the above purpose, the invention provides the following technical scheme: a power steering oil storage tank device comprises a tank body with an installation cavity, a filter element arranged on the tank body, an oil scale, an opening is provided at the axial end of the tank body installation cavity, a tank cover is arranged at the opening, and a sealing part is arranged between the tank cover and the tank body. The tank body is provided with an inlet oil pipe and an outlet oil pipe with its installation cavity, the installation cavity is provided with a tank locking mechanism, the tank body locking mechanism includes a filter core shaft arranged in the filter core, the axial end of the filter core shaft is threaded with the inlet oil pipe, and the other end is locked with a locking head extended to the outside of the tank body, which is characterized in that the tank lid is detachable connected with the tank body. A connecting edge is arranged parallel to the side wall of the tank body, and an elastic flanging edge is arranged between the connecting edge and the tank body, and a pressing space is arranged between the elastic flanging edge and the inner wall of the tank body, and the seal is arranged in the pressing space; The filter core shaft is arranged towards one end of the opening of the tank body, and the oil scale is inserted in the cavity, and the locking head is a knob connected with the oil scale.

[0006] Using the above technical solution, the tank body and the tank cover are connected through the elastic flanging edge on the tank cover. The elastic pressure of the elastic flanging edge on the tank cover can not only seal the seal, but also ensure the tightness of the seal between the tank body and the tank cover, so that there will be no leakage. Moreover, the elastic flanged edge contradicts the elastic pressure of the seal on the side wall of the tank through the seal, so that the lid can be firmly installed on the tank; The oil scale is inserted in the filter core shaft of the filter core, so that the oil scale and the locking mechanism of the tank are connected together. In the process of processing, the oil scale does not need to be installed separately, which reduces the processing process, reduces the assembly time, and reduces the production cost.
[0007] The invention is further arranged as follows: the elastic flanged edge comprises a flanged edge arranged parallel to the connecting edge and connected by an arc connecting strip, an arc transition edge arranged relative to the other end of the connecting end with the arc connecting strip, and a straight edge connected with the arc transition edge and extended towards the tank body, and the straight edge is arranged vertically with the side wall of the tank body. The other end of the straight edge connected with the arc transition edge is provided with a buckle retaining edge connected vertically with the straight edge and extending towards the tank body; The cross section of the seal is in the shape of "L", including a short side and a long side, the short side is sealed with the opening of the tank body, and the two sides of the long side are respectively provided with at least one sealing bump and the inner wall of the tank body and the folding edge.
[0008] Using the above technical solution, the elasticity of the elastic flapping edge is good, and the setting of the retaining edge can prevent the external media or corrosive media from entering the sealing place between the tank lid and the tank body to cause damage to the seal, and play a protective role in the seal; The sealing parts adopt the way of multi-point sealing, so that the sealing performance is improved, and the sealing of the tank body and the lid is guaranteed.
[0009] The invention is further arranged as: the can cover is provided with an elastic installation opening at the installation point of the oil scale, the elastic installation opening is provided with an elastic oil baffle, the edge of the elastic installation opening is provided with an elastic folding edge, and the sealing pad is provided between the elastic oil baffle frame and the elastic folding edge; The elastic oil baffle frame comprises a frame body in the shape of "U" in cross section and a skirt which is arranged at the opening of the frame body and is folded towards the outside of the frame body. A sealing ring is arranged between the skirt edge and the knob of the oil scale.
[0010] The skirt edge is provided with a bulge towards the sealing ring, and the vertex of the bulge is sealed against the sealing ring.
[0011] After the above technical solution is adopted, a two-stage sealing method is adopted between the oil scale and the tank lid to greatly improve the sealing performance.
[0012] The invention is further described below in conjunction with the attached drawings.
