Abstract

The invention relates to a power disc, a torsion damper using the power disc, a transmission system and an automobile. The power disc comprises a disc body of which the axis extends in the left-right direction. At least two rubber mounting holes which are throughout the disc body in the left-right direction are formed in the disc body in the circumferential direction. Damping rubber sleeves are arranged in the rubber mounting holes. The damping rubber sleeves are provided with inner rubber holes allowing corresponding connecting pieces to penetrate in the axial direction, and walls of the holes are in force transmission fit with the connecting pieces in the radial direction. The power disc in the torsion damper drives a rotational inertia disc to rotate through the damping rubber sleeves and the connecting pieces arranged in the inner rubber holes of the damping rubber sleeves, and the damping frequency of the damper can be adjusted by changing the number of the connecting pieces. Meanwhile, as the connecting pieces are arranged in the inner rubber holes of the damping rubber sleeves, the connecting pieces play a role in driving the rotational inertia disc to rotate and also play a role in preventing the damping rubber sleeves from deforming excessively; besides, there is no need to additionally arrange centering and limiting elements, so the structure is simple.

Description

technical field [0001] The invention relates to a power disc, a torsional shock absorber using the power disc, a transmission system and an automobile. Background technique [0002] Passenger cars generally use diesel engines as driving devices. Diesel engines are compression ignition internal combustion engines. Compared with gasoline engines, the compression ratio is larger, the combustion process is violent, and the torsional vibration is large, which makes the vibration and noise of the whole vehicle louder. In addition, the torsional vibration of the crankshaft is transmitted to the transmission system, causing the torsional vibration problem of the transmission system, resulting in large noise of the rear axle and affecting the comfort of the vehicle. [0003] An effective measure to reduce the torsional vibration of the drive train is to use a torsional dynamic vibration absorber. However, the frequency band of the commonly used dynamic vibration absorber is relativel...
