Abstract
Disclosed is a four-patch counterbalance block for a 474Q spherical graphite crankshaft, which is characterized in that the four-patch counterbalance block comprises a spherical crankshaft body molded integrally from cast iron; a first main journal, a first rod journal, a second main journal, a second rod journal, a third main journal, a third rod journal, a fourth main journal, a fourth rod journal and a fifth main journal are arranged sequentially from left to right on the spherical crankshaft body; four counterbalance blocks are arranged respectively between the first main journal and the first rod journal, between the third main journal and the second rod journal, between the third main journal and the rod journal, and between the fifth main journal and the fourth rod journal. With such a technical proposal, the four-patch counterbalance block has the advantages of light weight and low making cost, which is not only capable of improving the accelerating performance of the engine but also capable of remarkably minimizing the internal rotation resistance when the linkage mechanism of the crankshaft rotates with high speed, thus reducing oil consumption and noise. .
Description
Technical field
The utility model relates to the component on a kind of motor car engine, particularly a kind of four cylinder engine bent axle.
Background technique
Motor is the heart of automobile, and bent axle is one of key components and parts in the motor car engine motion width of cloth.The four cylinder engine bent axle of each engine production enterprise production of existing domestic automobile industry, basically be to adopt 8 traditional equilibrium block crankshaft structures, with 8 equilibrium blocks of 474Q ductile iron crankshaft is example, in conjunction with Fig. 1 as can be known, it comprises five main journals, four rod journals and eight equilibrium blocks, and the shortcoming of the bent axle of this structure is: 1, volume is big; 2, its weight generally at 9.8 kilograms, makes Heavy Weight; 3, because Heavy Weight makes the rotary inertia loss of engine start or braking big after installation, acceleration performance is poor, the oil consumption height; 4, consumptive material, cost height; 5, the computing ballance correction of bent axle directly influences engine performance: 8 equilibrium blocks: dynamically balanced amount of unbalance is≤150gmm.
Summary of the invention
The purpose of this utility model just provides a kind of in light weight and low 4 equilibrium blocks of 474Q ductile iron crankshaft of cost of production.
The utility model is achieved through the following technical solutions, be 4 equilibrium blocks of a kind of 474Q ductile iron crankshaft, it is characterized in that: it comprises the circular bent axle body by the ironcasting single forming, from left to right be furnished with first main journal on this bent axle body successively, the first connecting rod axle journal, second main journal, the second connecting rod axle journal, the 3rd main journal, the third connecting rod axle journal, the four main neck, the 4th rod journal and the 5th main journal are between first main journal and first connecting rod axle journal, between the 3rd main journal and the second connecting rod axle journal, be provided with a slice equilibrium block between the 3rd main journal and the third connecting rod axle journal and between the 5th main journal and the 4th rod journal.
The utility model adopts 4 equilibrium blocks, and it is compared with existing 8 equilibrium blocks, and its weight has only 8.6 kilograms, the weight that it obviously alleviates, and it is about 12.25% to have saved raw material, and the also corresponding minimizing of machining allowance has reduced cost of production simultaneously.
Owing to adopted technique scheme, the utlity model has following advantage:
1, this bent axle weighs 8.6 kilograms, and is lighter 1.2 kilograms than existing 474Q bent axle, and it is about 12.25% to save material, and the rotary inertia loss of car engine start and braking reduced, thereby reduced oil consumption;
2, the corresponding minimizing of machining allowance makes every unit price reduce nearly 20 yuan of expense, has also improved manufacturing efficiency when having reduced cost of production;
3, equilibrium block quantity reduces, and engine acceleration can be improved greatly, connecting rod inner rotational resistance under the state of running up is obviously reduced, thereby reduce oil consumption and noise.
4, the computing ballance correction of bent axle directly influences engine performance: the dynamically balanced amount of unbalance of 4 equilibrium blocks is≤75gmm, because the amount of unbalance of 4 equilibrium block bent axles has only 8 equilibrium block bent axles half, so, the motor of 4 equilibrium block bent axles during than the engine running of 8 equilibrium block bent axles vibration little, its stable working is good, also is better than the motor of 8 equilibrium block bent axles aspect anti-resonance.

Among the figure: 1. bent axle body; 2-1. first main journal; 2-2. second main journal; 2-3. the 3rd main journal; 2-4. four main neck; 2-5. the 5th main journal; 3-1. first connecting rod axle journal; 3-2. second connecting rod axle journal; 3-3. third connecting rod axle journal; 3-4. the 4th rod journal; 4. equilibrium block.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 2, the utility model comprises the circular bent axle body 1 by the ironcasting single forming, from left to right be furnished with the first main journal 2-1 on this bent axle body 1 successively, first connecting rod axle journal 3-1, the second main journal 2-2, second connecting rod axle journal 3-2, the 3rd main journal 2-3, third connecting rod axle journal 3-3, four main neck 2-4, the 4th rod journal 3-4 and the 5th main journal 2-5 are between first main journal and first connecting rod axle journal, between the 3rd main journal and the second connecting rod axle journal, be provided with a slice equilibrium block 4 between the 3rd main journal and the third connecting rod axle journal and between the 5th main journal and the 4th rod journal.
Described equilibrium block 4 can be fan-shaped, also can be curved.
In sum, the utility model adopts 4 equilibrium blocks, and it is compared with existing 8 equilibrium blocks has long-pending its significant effect, its weight has only 8.6 kilograms, and the weight that it obviously alleviates has been saved raw material about 12.25%, the also corresponding minimizing of machining allowance has reduced cost of production simultaneously; Equilibrium block quantity reduces, and engine acceleration can be improved greatly, connecting rod inner rotational resistance under the state of running up is obviously reduced, thereby reduce oil consumption and noise; The computing ballance correction of bent axle directly influences engine performance: the dynamically balanced amount of unbalance of 4 equilibrium blocks is≤75gmm, because the amount of unbalance of 4 equilibrium block bent axles has only 8 equilibrium block bent axles half, so, the motor of 4 equilibrium block bent axles during than the engine running of 8 equilibrium block bent axles vibration little, its stable working is good, also is better than the motor of 8 equilibrium block bent axles aspect anti-resonance.
