Rubber spacer light track structure with vibration reduction and noise reduction functions
The invention discloses a rubber spacer light track structure with vibration reduction and noise reduction functions. The rubber spacer light track structure with the vibration reduction and noise reduction functions comprises a track beam, tracks and rubber pads, wherein the track beam comprises two track beam bodies which are used for fixing the tracks and arranged oppositely in parallel, the cross section of the track beam bodies is rectangular, and the extending direction of the track beam bodies is the same with the extending direction of the two tracks; connection rods used for increasing the anti-bending inertia moment of the track beam in the sectional direction are arranged between the track beam bodies, the multiple rows of connection rods keep flush with the top face and the bottom face of the track beam bodies, the sectional shape is set to be the same double-layer connection rods, the plane where the double-layer connection rods at any tow is perpendicular to the lateral face of the track beam bodies, and arc transition sections are arranged at the positions, connected with the track beam bodies, of the connection rods; each rubber pad is mainly formed by connecting multiple rubber layers made of high-damping rubber materials. The rubber spacer light track structure with the vibration reduction and noise reduction functions increases the transverse connection stiffness and the sectional anti-bending inertia moment of the track beam, and can greatly reduce environment vibration and noise.
