Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile leaf springs, in particular to a steel plate with a noise reduction function. Background Art
[0002] Leaf spring is the most widely used elastic element in automobile suspension. It is an elastic beam of approximately equal strength composed of several alloy spring leaves of equal width but unequal length. Leaf spring involves the superposition of steel plates.
[0003] Existing steel plates usually do not have the function of preventing dislocation. During the movement of the car, the steel plate will be subject to bumps and vibrations, and the steel plate will be dislocated to a certain extent around the fixed axis. When the dislocation is serious, the shock absorption effect of the steel leaf spring will deteriorate, affecting the driving of the car. It also does not have a good dust-proof effect. The steel leaf spring will constantly come into contact with dust raised by the road surface during the driving of the car. The dust will be blocked in the gap of the steel leaf spring, thereby deteriorating the performance of the steel leaf spring and causing inconvenience to the driver during the driving process.
[0004] In order to solve the above technical problems, we designed a steel plate with noise reduction function. Utility Model Content
[0005] The utility model aims to provide a steel plate with noise reduction function, which has the function of preventing dislocation and having good dustproof effect, thereby solving the problem that the steel plate usually does not have the advantage of preventing dislocation and has a general dustproof effect.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel plate with noise reduction function, comprising a steel plate body, the top of the steel plate body is provided with connecting holes and a three-way groove in sequence from left to right, the inner cavity of the three-way groove is provided with an anti-error mechanism, a branch groove is provided on the right side of the top of the steel plate body, the bottom of the steel plate body is fixedly connected with a noise reduction spring and an auxiliary rod in sequence from left to right, and a first shock-absorbing pad is provided on the top of the steel plate body.
[0007] Preferably, the error-proofing mechanism includes a rotating rod, which is movably connected to the inner cavity of the three-way groove through a rotating shaft, a rectangular hole is opened on the right side of the top of the rotating rod, compression springs are fixedly connected to the right side of the front side and the right side of the rear side of the rotating rod, and second shock-absorbing pads are fixedly connected to the front and rear sides of the rotating rod.
[0008] Preferably, a circular groove is opened on the right side of the top of the steel plate body, and the first shock-absorbing pad is fixedly connected to the inner cavity of the circular groove.
[0009] Preferably, a supporting edge is fixedly connected to the right side of the bottom of the steel plate body, and a third shock-absorbing pad is fixedly connected to the surface of the supporting edge.
[0010] Preferably, a guide plate is fixedly connected to the right side of the bottom of the steel plate body, and a guide groove is provided at the bottom of the guide plate.
[0011] Preferably, both the front and rear sides of the three-way groove are connected to the branch groove, and the right side of the branch groove extends to the right side of the steel plate body.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] 1. The utility model has the advantage of preventing misalignment through the cooperation of the anti-misalignment mechanism, the auxiliary rod, the first shock-absorbing pad, the rectangular hole, the compression spring, the second shock-absorbing pad and the support edge. When misalignment occurs between the steel plates, the auxiliary rod can drive the rotating rod to rotate, so that the compression spring works, thereby playing a role of auxiliary resetting, and the support edge can also play a role of auxiliary anti-misalignment, and the rotation of the left side of the rotating rod can accelerate the flow of gas in the three-way groove to the branch groove, so that the flow of dust between the gaps is accelerated, thereby improving the dust removal effect.
[0014] 2. The utility model has the advantage of better dust removal effect through the cooperation of the three-way groove, the branch groove, the rotating rod, the support edge, the third shock-absorbing pad, the guide plate and the guide groove. The guide plate and the guide groove can pre-guide the gas, and the dust entering the gap between the steel plates will flow along the branch groove. The relative movement between the support edge and the branch groove will also accelerate the dust flow speed, which is beneficial to improving the shock-absorbing effect of the leaf spring.

[0019] See also Figure 1-Figure 3A steel plate with noise reduction function includes a steel plate body 1, a connecting hole 2 and a three-way groove 3 are opened on the top of the steel plate body 1 from left to right, an anti-error mechanism 4 is arranged in the inner cavity of the three-way groove 3, a support groove 5 is opened on the right side of the top of the steel plate body 1, a noise reduction spring 6 and an auxiliary rod 7 are fixedly connected to the bottom of the steel plate body 1 from left to right, and a first shock-absorbing pad 8 is arranged on the top of the steel plate body 1.
[0020] See also Figure 1 and Figure 3 The anti-error mechanism 4 includes a rotating rod 9, which is movably connected to the inner cavity of the three-way groove 3 through a rotating shaft. A rectangular hole 10 is opened on the right side of the top of the rotating rod 9. The right side of the front side and the right side of the rear side of the rotating rod 9 are fixedly connected with a compression spring 11. By setting the rotating rod 9 and the compression spring 11, the process of resetting the steel plate can be facilitated, thereby achieving an anti-error effect. The front and rear sides of the rotating rod 9 are fixedly connected with a second shock-absorbing pad 12.
[0021] See also Figure 1 and Figure 2 A circular groove is opened on the right side of the top of the steel plate body 1, and the first shock-absorbing pad 8 is fixedly connected to the inner cavity of the circular groove. By arranging the first shock-absorbing pad 8 and the noise reduction spring 6, it can play a role in shock absorption and noise reduction, which is beneficial to the operation of the steel leaf spring.
[0022] See also Figure 1 and Figure 2 A support rib 13 is fixedly connected to the right side of the bottom of the steel plate body 1. By setting the support rib 13 and the support groove 5, the flow of gas between the gaps of the steel plates can be accelerated, thereby achieving a good dust removal effect. A third shock-absorbing pad 14 is fixedly connected to the surface of the support rib 13.
[0023] See also Figure 2 A guide plate 15 is fixedly connected to the right side of the bottom of the steel plate body 1, and a guide groove 16 is provided at the bottom of the guide plate 15. By arranging the guide plate 15 and the guide groove 16, a pre-drainage effect can be achieved, so that the amount of dust accumulated in the gap of the steel plate is small.
[0024] See also Figure 1 and Figure 2 The front and rear sides of the three-way groove 3 are connected to the branch groove 5. By setting the three-way groove 3 and the branch groove 5, the flow of gas can be accelerated by the rotation of the rotating rod 9 to improve the dust removal efficiency. The right side of the branch groove 5 extends to the right side of the steel plate body 1.
[0025] When in use, when the leaf spring moves forward with the vehicle, dust flows between the steel plate body 1 and the lower steel plate, and the air flow moves along the guide groove 16. Part of the dust can be guided to both sides of the leaf spring, and the dust entering the gap can flow into the branch groove 5. The gas flows along the branch groove 5 to the front and rear sides of the steel plate body 1, which plays a dust-proof role. When misalignment occurs between the steel plates, the support edge 13 of the upper steel plate and the branch groove 5 of the lower steel plate move relative to each other, which is beneficial to the flow of dust. Since the auxiliary rod 7 is stuck in the rectangular hole 10, the auxiliary rod 7 will drive the rotating rod 9 to rotate when the steel plates are misaligned, and the left side of the rotating rod 9 moves back and forth, thereby accelerating the flow of gas in the three-way groove 3, and then accelerating the flow of gas in the branch groove 5, which is beneficial to improving the dust removal effect. When the rotating rod 9 rotates, the compression spring 11 works to play a resetting role. The second shock-absorbing pad 12 can play a buffering role between the three-way groove 3 and the rotating rod 9, and the noise reduction spring 6 and the first shock-absorbing pad 8 can play a role of shock reduction and noise reduction when the leaf spring is working, which is beneficial to the driving process.
[0026] In summary: the steel plate with noise reduction function, through the cooperation of the anti-misalignment mechanism 4, the auxiliary rod 7, the first shock-absorbing pad 8, the rectangular hole 10, the compression spring 11, the second shock-absorbing pad 12, the support edge 13, the three-way groove 3, the support groove 5, the rotating rod 9, the support edge 13 and the third shock-absorbing pad 14, solves the problem of usually not having the advantage of anti-misalignment and the general dust-proof effect.
