Abstract

The invention discloses a crankshaft balance structure, which includes balance weights respectively arranged on several groups of crank arms with equal weight, and also includes a first counterweight arranged at the front end of the crankshaft and a second counterweight arranged at the rear end of the crankshaft. The mass of the first balance weight and the second balance weight are equal, the direction of the center of mass is opposite, and the direction of the center of mass of one of them is the same as the direction of the center of mass of the balance weight on the adjacent crank arm. In this way, the balance of the inertial force is maintained through the characteristics of the first counterweight and the second counterweight being equal in weight and reversed, and at the same time, one of them is in the same direction as the center of mass of the counterweight on the adjacent crank arm, so that the rotational inertia moment can be achieved Full balance and semi-balance of reciprocating inertia moment meet the basic balance design goal of the crankshaft system. Compared with the existing technology, there is no need to change the structure of the front and rear parts of the engine (such as the flywheel), which improves the universality and versatility . The invention also discloses an engine and a vehicle, the beneficial effects of which are as described above.
