A limiting protrusion 113 is provided at the lifting start end of the installation groove 11, and the limiting protrusion 113 is located on the side of the notch groove 114 opposite to the lifting direction of the spring 2, so as to prevent the clamping foot 21 from being separated from the notch groove 114 during the process of the spring 2 reciprocatingly compressing, deforming and restoring the deformation, and the clamping foot 21 is limited on the limiting protrusion 113, and will not be further displaced along the descending direction of the installation groove 11, causing wear to the cushion body at the lifting start end of the installation groove 11. Preferably, the limiting protrusion 113 is made of a material with strong rigidity to effectively limit the spring foot of the spring end ring and avoid stress wear on the rubber material part of the cushion body.
[0044] In one embodiment, in order to movably fix the spring foot in another simple design manner to completely eliminate the problem of water accumulation caused by the blockage of the water flow hole 111 due to the interference of the spring end ring, and effectively solve the problem of premature loss of the back side of the cushion body caused by stress concentration at the separation point between the spring 2 and the cushion body, the present application provides a new spring cushion, including a spring mechanism and a cushion mechanism, the spring mechanism includes a plurality of springs 2; the cushion mechanism includes a cushion body and a plurality of mounting grooves 11 provided on the cushion body, the plurality of mounting grooves 11 all have a cavity matching the spring end ring, a water flow hole 111 is opened at the groove bottom lift starting end of the mounting groove 11, a first groove 112 is opened at the groove bottom located on the outer periphery of the water flow hole 111, and a second groove 116 is opened on the back side of the cushion body corresponding to the separation point between the spring end ring and the mounting groove 11. A limiting protrusion 113 is provided at the lifting starting end of the mounting groove 11, and the limiting protrusion 113 is located on the side of the notch groove 114 opposite to the lifting direction of the spring 2, so as to prevent the clamping foot 21 from being separated from the notch groove 114 during the process of the spring 2 reciprocatingly compressing, deforming and recovering its deformation, and the clamping foot 21 is limited on the limiting protrusion 113, and will not be further displaced along the descending direction of the mounting groove 11, causing wear to the cushion body at the lifting starting end of the mounting groove 11. The limiting protrusion 113 is provided with a first magnetic element, and the spring foot of the spring end ring extends outward to form a clamping foot 21, and the end of the clamping foot 21 adopts a second magnetic element. The clamping foot 21 is magnetically attracted to the first magnetic element on the limiting protrusion 113 during the repeated compression and deformation of the spring 2 by magnetic attraction, so as to separate the gap between the spring end ring and the first groove 112, avoid the water flow hole 111 to the maximum extent and avoid the possibility of the spring end ring contacting with the accumulated water and causing rust, and completely eliminate the technical problem of the spring end ring blocking the water flow hole 111. There is no need to open the notch groove 114, and the processing and installation are simpler and more convenient. It can also avoid the accumulation of moisture when a large amount of water is accumulated in the installation groove 11, which overflows directly from the notch groove 114 to the cushion body and causes mildew and rot. The active adsorption method of the spring foot is relative to the fixed clamping method of the spring foot, and will not cause structural loss to the repeated compression and deformation of the spring 2, thereby affecting its reset ability.
[0045] In a more specific embodiment, the groove depth of the first groove 112 is 2-5 mm, and the groove depth of the second groove 116 is 1-3 mm. In a more specific embodiment, the groove depth of the first groove 112 is 2.6 mm, and the groove depth of the second groove 116 is 1.5 mm.
[0046] In the second aspect, based on the same inventive concept, the present application provides a suspension, including a control arm and the novel spring cushion as described above. The suspension provided by the present application has a novel spring cushion with a first groove 112 provided on the periphery of the water flow hole 111 and a second groove 116 provided on the back of the cushion body corresponding to the separation point between the cushion body and the spring end ring, so that the spring 2 is not easily corroded, and the cushion body is not easily damaged prematurely due to the repeated compression stress concentration of the spring 2.
[0047] On the third aspect, based on the same inventive concept, the present application provides a vehicle, characterized in that it includes the suspension as described above. The vehicle provided by the present application has better anti-water accumulation and anti-corrosion performance and is more durable due to the use of the above suspension.
