Description
Technical field
The present invention relates to general gasoline engines and manufacture field, particularly relate to a kind of crankcase.
Background technology
The generally crankcase of electromotor is the important composition parts of electromotor equal power device, and crankcase includes casing
And the cylinder block two parts combined as a whole with casing.The effect of box-like body is to install bent axle, has in electromotor works
Important effect.Existing crankcase, simple in construction, function is the most single, it is impossible to meet use demand.Therefore, it should
A kind of new technical scheme is provided to solve above technical problem.
Summary of the invention
It is an object of the invention to: for above-mentioned deficiency, it is provided that a kind of rational in infrastructure, the crankcase that using effect is good.
For achieving the above object, the technical solution used in the present invention is:
A kind of crankcase, including box-like body, cylinder block, described box-like body is provided with inverted sections, and described casing is originally
The middle part of body is provided with bent axle borehole jack, and the bottom of described box-like body is provided with base, and the outside of described bent axle borehole jack is that divergent shape sets
Multiple reinforcement, one end of described reinforcement is had to be connected to inside the correspondence position of bent axle borehole jack outer, the other end and inverted sections
The correspondence position of wall connects, and the inwall of the lower plane distance box-like body of described reinforcement has certain height, at least one institute
Stating and be provided with at least one vibration absorbing structure on reinforcement, the bottom of described crankcase is provided with the heat radiation that a row is parallel to each other
Sheet, the top of described fin is connected as a single entity with box-like body.
Further technical scheme is:
Described shock sucking structure is dynamic vibration absorber.
Air channel through before and after being provided with in the angle region that the bottom of described cylinder block and box-like body are formed.
Due to the application of technique scheme, the present invention compared with prior art has the advantage that
1, the crankcase of the present invention, at least one described reinforcement is provided with at least one dynamic vibration absorber, and it can
To absorb the vibration that crankcase inner body produces in the course of the work, making gasoline engine operating reliable, fault rate is few, Ke Yiyan
Its service life long.
2, the crankcase of the present invention, is provided with, in the bottom of crankcase, the fin that a row is parallel to each other, at cylinder
Air channel through before and after being provided with in the angle region that the bottom of body and crankcase are formed, the design of such structure can effectively be dropped
Low block temperature, makes gasoline engine operating reliable, and fault rate is few.
Accompanying drawing explanation
Accompanying drawing 1 is present configuration schematic diagram.
In the figures above: 1, box-like body, 2, bent axle borehole jack, 3, cylinder block, 4, reinforcement, 5, inverted sections, 6, absorbing knot

Body 1 is connected as a single entity.
Preferably as second embodiment, the present embodiment is the further restriction to embodiment one, described shock sucking structure
6 is dynamic vibration absorber.
Preferably as the 3rd embodiment, the present embodiment is the further improvement to embodiment one, described temperature-sensing element
6 are installed on inner chamber end face by the way of silk-screen or stickup.
Preferably as the 4th embodiment, the present embodiment is the improvement to embodiment one, the bottom of described cylinder block with
Air channel 9 through before and after being provided with in the angle region that box-like body 1 is formed.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, on the premise of without departing from principle of the present invention, it is also possible to make some improvement or replacement, these improve or replace also
Should be regarded as protection scope of the present invention.
