Problems solved by technology
However, it is difficult to change the stiffness of the coil spring after it is selected.
The air spring is a part of the computer suspension system, and it needs to be used in conjunction with the sensor and the actuator. It is actively controlled. Its overall structure is complex, consumes energy, and the manufacturing cost and use cost are high. The peer-to-peer connection affects the original use height space of the vehicle

specific Embodiment approach 2
[0011] The outer spring rigidity of the helical spring is large, and the internal spring rigidity is small, and the basic socket connection method is the same as the specific embodiment, except that the rubber washer is set to the bottom 5 of the spring connection sleeve accordingly.
specific Embodiment approach 3
[0012] The helical spring connecting sleeve can be used upside down, and the rubber gasket and the sand leak are changed accordingly, and the socketing method is basically the same as the specific embodiment.
[0013] More ideal is the specific implementation mode 1. Because the contact between the top of the spring connecting sleeve and the rubber washer and the spring buckle plate is far away from the wheel, the edge of the buckle plate extends downward to cover a part of the outer spring, so that the silt thrown up by the wheel will And the water will not fall to the joint between the top of the sleeve and the buckle plate, which improves the service life of the spring connection sleeve (including the rubber washer).

The invention discloses a spiral spring connecting device (a spiral spring connecting sleeve) for vibration reduction of automobiles, which is characterized in that two spiral springs with different diameters and different rigidities are sleeved together for using; one spring is arranged inside the sleeve, and the other spring is arranged outside the sleeve; and the external spring streches out of the top of the sleeve from the bottom of the sleeve, and the internal spring streches out of the bottom of the sleeve from the top of the sleeve. Firstly, the two springs are compressed simultaneously, when the springs are compressed to a certain space, after the part of the spring with small rigidity, stretching out of the sleeve, is compressed, the top or bottom of the spring sleeve is in contact with a spring buckle disk or tray, and residual gravity and impact force are born by the spring with large rigidity. After the coupling use of two springs has the advantages that both of the non-loaded and fully-loaded vehicles have a good vibration reduction function on flat roads and rugged roads, thereby achieving the ideal goal of suspension control; and the used space of the original spiral spring can not be increased.
Description
Technical field: [0001] The invention relates to automobile vibration reduction, which is used for the socket connection of the elastic support element of the suspension - the coil spring. Background technique: [0002] Application number 200580030040X, name: long stroke strong long combined spring, the invention relates to a long stroke, variable elastic coefficient combined spring, including two springs with different coefficients, connected end-to-end, so that the piston and the middle convex The combination of the edge parts, the low elastic constant spring is compressed, and then the high elastic spring is compressed, each spring can be assembled separately and connected together to produce a combined spring, allowing different types of springs to be combined to meet specific application needs. [0003] Automotive suspension is divided into passive suspension, semi-active suspension and active suspension. The suspension is mainly composed of springs (such as leaf sprin...
