Abstract
The utility model discloses a fastening and sealing structure of a crankcase oil tray of a steel plate pressing piece, which comprises an extending part of the crankcase oil tray, an engine cylinder and a fastening bolt connected with the extending part of the crankcase oil tray and the engine cylinder, wherein a rubber sealing piece is arranged between the extending part of the crankcase oil tray and the engine cylinder; a hanging piece is arranged on the lower surface of the extending part of the crankcase oil tray; the rubber sealing piece is composed of a sealing stripe passed by the fastening bolt and a stopping stripe extending upward at the end part of the sealing stripe and contacting to the engine cylinder; and the hanging piece is composed of a connecting stripe passed by the fastening bolt and a compressing stripe extending upward at the end part of the connecting stripe. The fastening and sealing structure of a crankcase oil tray of a steel plate pressing piece applies to the way that fastening and sealing structure of a crankcase oil tray of a steel plate pressing piece has two sealing processes, so the aging of the sealing piece can be avoided, good fastening and sealing can be kept for a long time, and the maintenance cost and work load are reduced.
Description
Technical field
The utility model relates to motor car engine, relates in particular to a kind of fastening sealing structure of steel stamping part oil sump.
Background technique
On the present motor car engine, oil sump generally uses steel stamping part, the housing top of oil sump has the oil sump extension part with the engine cylinder-body sealing, with the oil sump extension part directly with bolton to engine cylinder-body, and adopt the sealer sealing, when the volume of oil sump bigger, the planeness of oil sump extension part is difficult to guarantee, sealing effect is relatively poor, need to adopt seal ring to bring sealing, and seal band is easily aging, and the sealing of oil sump was lost efficacy gradually, oil leakage phenomenon can occur after a period of time, replacing just needs repairing.
The model utility content
Technical problem to be solved in the utility model provides a kind of fastening sealing structure of steel stamping part oil sump, and the fastening sealing structure of this kind steel stamping part oil sump can keep good fit sealing for a long time, has reduced maintenance cost and workload.
Solve this technical problem, the technical solution of the utility model is: a kind of fastening sealing structure of steel stamping part oil sump, comprise the oil sump extension part, engine cylinder-body and the clamping bolt that is connected oil sump extension part and engine cylinder-body, be provided with rubber seal between described oil sump extension part and the engine cylinder-body, the lower surface of described oil sump extension part is provided with suspender member, described rubber seal is made up of with the upwardly extending blend stop that contacts with engine cylinder-body in Stamping Steel Ribbon end the Stamping Steel Ribbon that clamping bolt passes, and described suspender member is made up of the upwardly extending pressing bar of connection strap and connection strap end that clamping bolt passes.
The blend stop of described rubber seal and the surface of contact of engine cylinder-body are rough surface.
The rough surface of described rubber seal is the cambered surface of inwardly shrinking.
The lower surface of the connection strap of described suspender member has resilient pad.
The fastening sealing structure of a kind of steel stamping part oil sump of the utility model is adopted in such a way, has two seals, can avoid Sealing aging, can keep good fit sealing for a long time, has reduced maintenance cost and workload.
Description of drawings
Below in conjunction with accompanying drawing the fastening sealing structure of a kind of steel stamping part oil sump of the utility model is done explanation in further detail:
Fig. 1 is the schematic representation of the fastening sealing structure of a kind of steel stamping part oil sump of the utility model;
Fig. 2 is the structural representation of rubber seal shown in Figure 1;
Fig. 3 is the structural representation of suspender member shown in Figure 1;
In Fig. 1, Fig. 2, Fig. 3,1, engine cylinder-body; 2, oil sump extension part; 3, clamping bolt; 4, resilient pad; 5, suspender member; 6, rubber seal; 7, blend stop; 8, Stamping Steel Ribbon; 9, pressing bar; 10, connection strap; 11, bolt hole.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, a kind of fastening sealing structure of steel stamping part oil sump, comprise oil sump extension part 2, engine cylinder-body 1, clamping bolt 3, rubber seal 6 and suspender member 5, rubber seal 6 is positioned between oil sump extension part 2 and the engine cylinder-body 1, the lower surface of oil sump extension part 2 has suspender member 5, rubber seal 6 is made up of with the upwardly extending blend stop that contacts with engine cylinder-body 7 in Stamping Steel Ribbon 8 ends the Stamping Steel Ribbon 8 that clamping bolt 3 passes, rubber seal 6 can produce distortion when sealing, blend stop 7 can inwardly shrink with the form of radian, in order to help sealing, the surface of contact of the blend stop of rubber seal 6 and engine cylinder-body 1 is selected rough surface, when the rough surface of rubber seal 6 is the cambered surface of inwardly shrinking, be more conducive to sealing; The lower surface of the connection strap 10 of suspender member 5 is placed with resilient pad.In the assembly process, rubber seal 6 is placed on the engine cylinder-body 1, then oil sump extension part 2 is compressed rubber seal 6, installing suspender member 5, suitably the blend stop with rubber seal 6 makes its distortion toward engine cylinder-body 1 side pressure, resilient pad 4 is installed again, with clamping bolt 3 pass connection strap, the oil sump extension part of resilient pad, suspender member successively, the Stamping Steel Ribbon of rubber seal is connected on the engine cylinder-body.Avoided oil sump and the soft of rubber material to contact like this, having reduced does not have bolt to contact existing danger, can carry out the sealing of two roads to cylinder body, and engine sump tank is played good sealing effect, good fit sealing be can keep for a long time, maintenance cost and workload reduced.
