Abstract
The utility model relates to a cylinder block of an automobile engine, in particular to a main bearing cap for the cylinder block of the automobile engine. A spring clamping piece is installed in the center of a main bearing cap body, a weight reduction groove is formed in the portion, at the upper end of the spring clamping piece, of the main bearing cap body, a rectangular locating groove is formed in the lower right end of the weight reduction groove in the longitudinal direction, and the spring clamping piece is movably arranged in the locating groove. By the adoption of the technical scheme, the main bearing cap for the cylinder block of the automobile engine has the advantages of being simple in structure and convenient to machine, saving raw materials, lowering the cost and effectively preventing the spring clamping piece on the main bearing cap body from falling off.
Description
Technical field
The utility model relates to a kind of automobile engine cylinder-body, by the structure of main bearing cap.
Background technique
Passenger car market requires harshness, reinforcing degree increasingly to improve day by day to engine performance at present, as the basic part of motor---the Design and manufacture of cylinder block also does more careful and more careful thereupon, do stricter and stricter, and main bearing cap is as carrying stress members important in cylinder block, can the height of its intensity works fine play vital effect for whole engine cylinder-body.Therefore, by main bearing cap structure do bearing capacity strong, factor of safety is large, could meet like this use requirement.As shown in Figure 1, in actual use, often can there is obscission in the spring card coordinating with main bearing cap, brings inconvenience to follow-up maintenance, also had a strong impact on the working life of cylinder block.
Summary of the invention
The purpose of this utility model is in order to solve above product failure risk, and a kind of automobile engine cylinder-body main bearing cap is provided, simple in structure, effectively avoids the spring card in main bearing cap to come off.
The technological scheme that the utility model adopted is for achieving the above object: a kind of automobile engine cylinder-body main bearing cap, main bearing cap center is provided with spring card, on the main bearing lid of spring card upper end, offer lightening grooves, lightening grooves bottom righthand side is offered a rectangular locating slot along the longitudinal, and spring card activity is placed in locating slot.
Described locating slot groove depth 5-7mm.
Owing to adopting technique scheme, the utlity model has following beneficial effect:
1, simple in structure, easy to process;
2, save raw material, reduce costs;
3, can effectively avoid the spring card in main bearing cap to come off.
Brief description of the drawings
Fig. 1 is traditional main bearing cap structural representation.
Fig. 2 is structural representation of the present invention.
In figure: 1 main bearing cap, 2 locating slots, 3 spring cards, 4 lightening grooves.
Embodiment
Below embodiment is illustrated:
A kind of automobile engine cylinder-body main bearing cap as shown in Figure 2, main bearing cap 1 center is provided with spring card 3, on the main bearing lid of spring card upper end, offer lightening grooves 4, lightening grooves bottom righthand side is offered a rectangular locating slot 2 along the longitudinal, the groove depth 6mm of locating slot, spring card activity is placed in locating slot.
Learn that by simulation the mode that spring card comes off is laterally to come off, adopt the utility model scheme, increase after rectangular locating slot in region along the longitudinal in main bearing cap, confirm by simulation, the intensity in this region of main bearing cap changes little, and has fundamentally stopped main bearing cap spring card and come off.
