Rotational angular velocity
1 drive ratio
main reduction ratio, the gear ratio means the driving axle of the final drive, which is equal to the ratio of the angular velocity of rotation of the shaft axle half-shafts, and also equal to the ratio of their rotational speeds.
have a greater impact on the car’s dynamic performance and fuel economy. Generally, the larger the reduction ratio of the main, strong acceleration performance and gradeability, and fuel economy is poor. However, if too large, it can not play the full power of the engine to achieve the desired speed. Drive ratio is smaller, the higher the maximum speed, better fuel economy, but poor acceleration and climbing ability.
