Description
Technical field
Engine field of sealing technology is the utility model is related to, more particularly to a kind of timing chain cover lid.
Background technology
Car engine timing transmission (the power transmission from bent axle to camshaft) system typically has three kinds of type of belt drive, i.e.,
Belt transmission, chain drive, gear drive etc., it is common for first two.For the engine using timing chain transmission, timing chain
Systematic part and engine interior driving parts necessarily contact, and caused mist of oil can be at this moment necessary to external diffusion in the course of work
Periphery is connected to gray iron to be sealed, avoid internal mist of oil from being leaked to external engine using timing chain cover lid.Start
Machine can produce various vibrations in the course of the work, while engine body temperature also raises, it is incident be exactly each part by
Thermal expansion, in the case, the mist of oil of engine interior may from timing chain cover lid and gray iron connection gap in ooze
Drain to outside.To ensure that engine interior mist of oil will not leak, it is desirable to the part of good sealing effectiveness, but timing chain
Cover lid connection engine cylinder-body and cylinder cap, span is big, realizes that the difficulty being fully sealed is larger.
Utility model content
The purpose of this utility model is to provide a kind of timing chain cover lid, it is ensured that with engine cylinder-body, cylinder cap, underframe
Mounting surface, which coordinates to form, to be tightly connected, and avoids mist of oil from revealing.
To achieve these goals, the utility model takes following technical scheme：A kind of timing chain cover lid, including cover lid sheet
Body, the both sides of bonnet body in the longitudinal direction are provided with flange, the installation of flange and engine cylinder-body, cylinder cap, underframe
Face corresponding matching, ramp down angle, the surface coating of described flange are provided between described flange and the side wall of bonnet body
There is silica gel.
In above-mentioned technical proposal, the screwed hole that the surface of flange is corresponded on the mounting surface of gray iron, underframe opens up
There is mounting hole, its fitting corresponding with mounting surface, bolt are uniformly passed through into installation again coated with silica gel in advance on the surface of flange
Hole carries out fastening installation with screwed hole, and silica gel is sealed the minim gap filling between flange and mounting surface, and silica gel exists
Being squeezed in installation process can extend to both sides, and a storage glue space silicon is at this moment formed between ramp down angle and mounting surface
Glue, avoid silica gel from directly falling in engine from being extruded between faying face, and store up glue space and fill up silica gel and greatly add
Strong sealing effectiveness.
Brief description of the drawings
Fig. 1 is the utility model schematic perspective view；
Fig. 2 is the utility model sectional perspective schematic diagram；
Fig. 3 is that the utility model flange coordinates sectional view；
Fig. 4 is the schematic perspective view that bonnet body is installed with gray iron, underframe.
Embodiment
Made further instructions with reference to 1~4 pair of the utility model of accompanying drawing：
A kind of timing chain cover lid, including bonnet body 10, the both sides of bonnet body 10 in the longitudinal direction are provided with flange
20, flange 20 and engine cylinder-body A, cylinder cap B, underframe C mounting surface corresponding matching, described flange 20 cover this with cover
Ramp down angle 21 is provided between the side wall of body 10, the surface of described flange 20 is coated with silica gel.The surface of flange 20 is corresponding
Cylinder body A, cylinder cap B, underframe C mounting surface on screwed hole offer mounting hole, uniformly applied in advance on the surface of flange 20
Silica gel is covered with again by its fitting corresponding with mounting surface, and bolt carries out fastening installation through mounting hole and screwed hole, and silica gel is by flange
Minim gap filling between side 20 and mounting surface is sealed, and silica gel is squeezed in installation process to be extended to both sides,
At this moment a storage glue space silica gel is formed between ramp down angle 21 and mounting surface, avoids silica gel from being directly squeezed between faying face
Go out to fall in engine, and store up glue space and fill up silica gel and greatly strengthen sealing effectiveness.
Described flange 20 is opened in corresponding cylinder body B and cylinder cap A join domain, cylinder body B and underframe C join domain
Provided with recess 22, described recess 22 is extended on ramp down angle 21.Cylinder body B and cylinder cap A, cylinder body B and underframe C when mounted two
Installation gap between two be present, corresponding to join provided with recess 22 and recess 22 with ramp down angle 21, at this moment silica gel, which is squeezed, to prolong
Extend in recess 22, forming continuous band with the silica gel on ramp down angle 21 blocks installation gap, further adds close
Seal effect.
The lower surface 11 of described bonnet body 10 is connected with engine oil pan D, is opened up on described lower surface 11
There is deep-slotted chip breaker 12, described deep-slotted chip breaker 12 joins with ramp down angle 21.Bonnet body 10 and cylinder body A, cylinder cap B, underframe C, which coordinate, to be connected
After connecing, its lower surface 11 is connected with oil pan D, is equally easy for accommodating silica gel and flange 20, ramp down provided with deep-slotted chip breaker 12
Silica gel on angle 21 forms continuous band, it is ensured that bonnet body 10 and oil pan D sealed connection.
The width of described flange 20 is more than 5mm, and the specification at ramp down angle 21 is 3mm × 30 °, and the specification of deep-slotted chip breaker 12 is
2mm × 45 °, the lower surface 11 of bonnet body 10 are higher than underframe C bottom surface.When oil pan D is installed, oil pan D's
Upper mounting surface is bonded with underframe C bottom surface, is existed between the lower surface of oil pan D upper mounting surface and bonnet body 10
Gap is installed, installation gap is that 0.15mm or so is easy to accommodate silica gel, because under engine behavior, bonnet body 10 can be by
The enough distortion allowances of bonnet body 10 are left in thermal expansion, installation gap for.
The surface of described flange 20 is uniformly laid with the raised line of reticulate pattern.Region between the raised line of reticulate pattern is used for
More silica gel are accommodated, add sealing effectiveness.
The surface middle part of described flange 20 uniformly offers the distance between mounting hole 23, adjacent mounting hole 23 and is in
Five times of the diameter of mounting hole 23 are between ten times of sizes.Specific arrangement mounting hole 23, the range of stress after fastening bolt can
The region covered between mounting hole 23 two-by-two, enhances sealing effectiveness.
The surface of described flange 20 is further opened with craft thread hole 24.Silica gel has stronger bonding effect, dismounting
Shi Renli is difficult to be dismantled, so coordinating provided with craft thread hole 24 and bolt, turn bolt is withstood to be made caused by flange
Firmly bonnet body 10 is separated with mounting surface.
