As shown in fig. 1 to 7, the automobile of the present invention includes a damper wheel 100 for a rotating body for connection with a crankshaft of the automobile by a belt.
The vibration damping wheel 100 for the rotating body comprises a belt pulley 1, a compression ring 2 arranged in the belt pulley 1 and fixed with the belt pulley 1, a rotating shaft 3 arranged in the belt pulley 1 and coaxially arranged with the belt pulley 1 and used for driving a rotor to rotate, a shaft sleeve 4 fixed with the rotating shaft 3, a vibration damping spring 5 propped between the shaft sleeve 4 and the compression ring 2 along the circumferential direction, a damping ring 6 sleeved outside or inside the rotating shaft 3, a damping sleeve 7 arranged between the damping ring 6 and the vibration damping spring, a self-lubricating bearing 8 arranged between the shaft sleeve 4 and the belt pulley 1 along the radial direction, sealing covers 9 arranged at two ends of the shaft sleeve 4 along the axial direction and a protective sleeve 10.
The belt pulley 1 is in interference fit with the compression ring 2, and the shaft sleeve 4 is in interference fit with the rotating shaft 3. The damping ring 6 is clamped and fixed with the compression ring 2 along the radial direction. The manner of securing of the present invention is not limited to an interference fit.
The self-lubricating bearing 8 can enable the belt pulley 1 to generate relative motion with the shaft sleeve 4 and the rotating shaft 3.
The damping sleeve 7 outside the damping ring 6 can increase the number of friction surfaces and the friction area. The damping ring 6 and the compression ring 2 are mutually fixed in the rotation direction in a clamping manner. The damping ring 6 may be made of nylon or the like. The damping sleeve 7 can be made of steel, aluminum, nylon and the like.
The protective sleeve 10 may be disposed between the rotating shaft 3 and the vibration isolation spring 5, or may be disposed between the vibration isolation spring 5 and the sleeve 4.
The vibration damping wheel 100 for a rotating body according to the present invention provides the following two embodiments according to the arrangement form of the vibration isolation springs of the spring main body 51.
Embodiment one:
As shown in fig. 2 to 5, in the present embodiment, the vibration isolation spring 5 includes a spring main body 51, a first catching portion 52 extending in a radial direction from one end of the spring main body 51, and a second catching portion 53 extending in a radial direction from the other end of the spring main body 51.
The damping ring 6 is sleeved on the inner side of the rotating shaft 3.
The first clamping portion 52 and the second clamping portion 53 are connected to the pressure ring 2 and the sleeve 4, respectively. Limiting grooves used for being clamped with the first clamping part 52 and the second clamping part 53 are respectively arranged on the compression ring 2 and the shaft sleeve 4.
As shown in fig. 5, when the vibration isolation spring 5 is in an uncompressed state, the damping sleeve 7 abuts against the vibration isolation spring 5, and the force point of the vibration isolation spring 5 is spaced from the first catching portion 52 by 90 degrees in the circumferential direction. When the vibration reduction wheel 100 for a rotating body is in a static state, the first circle of the vibration isolation spring 5 is in encircling contact with the damping sleeve 7, the torsion direction is in a free state, the vibration isolation spring 5 is precompressed along the axial direction, and the vibration isolation spring 5 is twisted in the torsion direction under the action of external torque, so that a positive pressure is generated for the damping ring 6 at a position where the first clamping part 52 forms an included angle of 90 degrees with the damping sleeve to generate damping.
In this embodiment, when the crankshaft drags the pulley 1 through the belt to accelerate, the compression ring 2 press-fitted with interference presses the first clamping portion 52 of the vibration isolation spring 5 and presses the vibration isolation spring 5, the vibration isolation spring 5 is tightly held and contracted, the second clamping portion 53 presses the shaft sleeve 4, and the rotating shaft 3 press-fitted with interference drives the rotator to rotate.
When the crank drags the pulley 1 to decelerate, the rotating shaft 3 and the shaft sleeve 4 continue to accelerate due to the inertia, the vibration isolation spring 5 expands, and the rotating shaft 3 and the pulley 1 rotate relatively. The spring rate of the vibration isolation spring 5 reduces the natural frequency of the system to a firing frequency well below idle speed, while the moment due to the load of the vibration reduction wheel 100 for the rotating body and the relative acceleration between the pulley 1 and the rotating shaft 3 creates a pressure on the damping sleeve 7 at a position 90 ° apart from the first catch 52 of the vibration isolation spring 5 and acts on the rotating shaft 3 through the damping ring 6, which pressure creates a great friction damping between the damping ring 6 and the rotating shaft 3 and between the damping ring 6 and the damping sleeve 7.
In particular, under some extreme conditions, the greater torque generated by the greater torsion angle of the vibration isolation spring 5 can generate greater friction damping, which can inhibit the speed fluctuation of the rotor under all orders and reduce the influence of the rotor on the accessory system. When the pulley 1 is rapidly decelerated, the pressure is reduced due to the expansion of the vibration isolation spring 5, and the friction damping is correspondingly reduced, so that the relative clutch rotation between the rotating shaft 3 and the pulley 1 is facilitated.
Embodiment two:
As shown in fig. 6 to 7, the compression ring 2 is provided with a first thread slope along the circumferential direction, the shaft sleeve 4 is provided with a second thread slope along the circumferential direction, and the first thread slope and the second thread slope respectively support against two ends of the vibration isolation spring 5.
When the vibration isolation spring 5 is in an uncompressed state, the damping sleeve 7 is abutted against the vibration isolation spring 5, and the stress point of the vibration isolation spring 5 and one end abutted against the vibration isolation spring 5 and the compression ring 2 are separated by 90 degrees along the circumferential direction.
When the vibration reduction wheel 100 for a rotating body is in a static state, the first circle of the vibration isolation spring 5 is in encircling contact with the damping sleeve 7, the torsion direction is in a free state, the vibration isolation spring 5 is precompressed along the axial direction, and the vibration isolation spring 5 is twisted in the torsion direction under the action of external moment, so that positive pressure is generated for the damping ring 6 at the position of an included angle of 90 degrees between one end of the vibration isolation spring 5, which is abutted against the compression ring 2, and the damping sleeve to generate damping.
The damping ring 6 is provided with a protruding part which is fixed with the compression ring 2 in the rotating direction, so that the compression ring 2 and the shaft sleeve 4 can rotate in a relative friction manner.
When the belt pulley 1 is dragged by the crankshaft to accelerate by the belt, one end of the vibration isolation spring 5 is extruded by the compression ring 2 in interference press fit with the belt pulley 1, the vibration isolation spring 5 is expanded under pressure, the other end of the vibration isolation spring is extruded by the shaft sleeve 4, and the rotor is driven to rotate by the rotating shaft 3 in interference fit with the shaft sleeve 4.
When the crankshaft drags the belt pulley 1 to decelerate, the rotating shaft 3 and the shaft sleeve 4 continue to accelerate under the action of inertia, the vibration isolation spring 5 contracts, and the rotating shaft 3 and the belt pulley 1 rotate relatively. The spring rate of the vibration isolation spring 5 reduces the natural frequency of the system to a much lower ignition frequency than idling, and at the same time, the moment due to the load of the vibration reduction wheel 100 for the rotating body and the relative acceleration between the pulley 1 and the shaft generates a pressure to the damping sleeve 7 at a position 90 ° apart from the vibration isolation spring 5, which is the end where the vibration isolation spring 5 and the compression ring 2 are abutted, and acts on the rotating shaft 3 through the damping ring 6, which generates a great friction damping between the damping ring 6 and the rotating shaft 3 and between the damping ring 6 and the damping sleeve 7. When the pulley 1 is rapidly decelerated, the pressure is reduced due to the shrinkage of the vibration isolation spring 5, and the friction damping is correspondingly reduced, so that the relative clutch rotation between the rotating shaft 3 and the pulley 1 is facilitated.
In the damper wheel 100 for a rotating body of the present invention, when a speed difference is generated between the pulley 1 and the shaft, the damper ring 6 rubs against the wall surface of the rotating shaft 3. Because the load and the angular acceleration of the vibration reduction wheel 100 for the rotating body cause the moment generated by the deflection angle of the vibration isolation spring 5 to act on the damping ring 6, a positive pressure is generated at the position of the vibration isolation spring 5 at a 90-degree interval to act on the damping ring 6, the positive pressure causes the relative friction between the damping ring 6 and the rotating shaft 3 to generate friction damping, and the damping can reduce the influence of the speed fluctuation of the rotational inertia of the rotating body on an engine accessory belt system.
According to the vibration reduction wheel 100 for the automobile and the rotating body, the vibration reduction spring 5 is arranged, so that the vibration reduction wheel 100 for the rotating body can reduce the natural frequency of a system to be far lower than the ignition frequency of idling through the spring rate of the vibration reduction spring 5; by providing the damping ring 6, vibrations at all orders are suppressed by high damping. The use of high damping allows the amplitude of the damper springs to be reduced, which is advantageous for improving the durability and life of the damper wheel 100 for a rotating body.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
