Description
Technical field
The utility model belongs to gearbox field, particularly relates to a kind of sedan gear-box housing.
Background technique
Existing sedan gear-box housing is Cast Steel, and comprises body, and the bottom surface of this body is a circle mould assembling face, mould assembling face circumferentially has one group of bolt and installs via hole.Simultaneously, the internal surface of bodies top has three bearing holes not of uniform size, and these three bearing holes are important, and wherein maximum bearing hole is through hole, all the other two bearing holes are blind hole, and maximum bearing hole and size bearing hole placed in the middle are on same straight line.
At present, casting gear box casing is from the side feed liquor of body, this casting mode easily causes sprue channel open away from the position of three bearing holes, the loss of velocity of casting liquid is larger, so just be easy to cause three bearing holes to produce the casting defects such as sbrinkage blowhole, and then cause blank up-to-standard rate lower, be badly in need of solving above-mentioned technical barrier for this reason.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of sedan gear-box housing, for ensureing the casting quality of three bearing holes, and ensures blank up-to-standard rate.
The technical solution of the utility model is as follows: a kind of sedan gear-box housing, the bottom surface of body (1) is a circle mould assembling face, this mould assembling face circumferentially has one group of bolt mounting holes (1a), three bearing holes (1b) not of uniform size are had at the internal surface at body (1) top, wherein maximum bearing hole (1b) is through hole, and all the other two bearing holes are blind hole, an outer side wall of described body (1) has a gear shift hole (1c) and three vehicle body attachment holes (1d), wherein gear shift hole (1c) opens on the termination at body (1) top, three described vehicle body attachment holes (1d) are tapped hole, these three vehicle body attachment holes are distributed on same leg-of-mutton three summits, it is characterized in that: on an outer side wall of described body (1), level is provided with a running channel and arranges muscle (1e), this running channel arranges that muscle opens the two ends to this outer side wall, and running channel arranges that wherein one end of muscle (1e) is connected with described gear shift hole (1c), described running channel arranges that muscle (1e) is solid construction, and its end face is plane, and its outer side surface is arc surface, and this arc surface is positioned at corresponding described bolt mounting holes (1a) inner side.
This case is designed more than adopting, arrange at running channel before being convenient to casting and muscle (1e) arranges running channel, thus intake from the side when casting, because running channel arranges that the position of muscle (1e) is close to three bearing holes (1b), molten steel just easily flows to three bearing hole (1b) places, thus avoid three bearing hole (1b) places to occur casting defect such as volume gas, sbrinkage blowhole etc. well, thus guarantee castability, and then ensure blank up-to-standard rate, so just overcome the defect of conventional construction well, and the utility model structure is simple, easy to implement.
The structural strength of muscle (1e) is arranged in order to strengthen running channel, running channel described in special envoy arranges that the end face and first of muscle (1e) is strengthened prominent muscle (1f) and second muscle (1g) of strengthening dashing forward and is connected, and these two reinforcements muscle of dashing forward are located on the outer side wall of described body (1) simultaneously; Described second strengthens prominent muscle (1g) is positioned at running channel layout muscle (1e) middle part, is positioned at the inner side that running channel arranges muscle (1e) outer side outside the prominent muscle of this second reinforcement; Described first strengthens prominent muscle (1f) is positioned at the second reinforcement and dashes forward between muscle (1g) and gear shift hole (1c), and this first protuberance strengthening prominent muscle is less than the second reinforcement muscle (1g) of dashing forward.
As preferably, described running channel arranges that the height (H) of muscle (1e) is 30 ± 1mm, and this running channel arranges that the outer side surface of muscle is the arc surface of evagination.
Beneficial effect: arrange at running channel before the utility model is convenient to casting and muscle arranges running channel, thus intake from the side when casting, because running channel arranges that the position of muscle is close to three bearing holes, molten steel just easily flows to three bearing hole places, thus avoid three bearing hole places to occur casting defect such as volume gas, sbrinkage blowhole etc. well, thus guarantee castability, and then ensure blank up-to-standard rate, so just overcome the defect of conventional construction well.
