Abstract
The utility model discloses a transmission vibration damping device for a clutch. The transmission vibration damping device comprises a driven hub, a driven gear and buffer stoppers, wherein the driven hub is provided with a plurality of projections, and assembly holes are formed on the projections respectively; the driven gear is assembled on the driven hub and provided with kidney holes with the same number as the projections, and the projections penetrate the kidney holes; and the buffer stoppers are arranged in the kidney hole and on the two sides of the projections, at least one buffer stopper is in clearance fit with the projections, and at least one buffer stopper is in interference fit with the projections. The buffering of the transmission vibration damping device is designed to be two-level buffering, and the projections of the driven hub are pre-pressed by the buffer stopper assembled in interference fit, thereby ensuring that no radial clearance exists between the driven gear and the driven hub, and a clearance is reserved between the projections of the driven hub and the buffer stopper assembled in clearance fit. When the driven gear of the clutch is under impact, the buffer stopper in interference fit is stressed at first to form the first-level buffering; and when the impact is too large, the buffer stopper in clearance fit takes part in the buffering, so as to form the second-level buffering. As two-level buffering is adopted, the buffering effect is better.
