It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 to fig. 3, a front axle suspension structure according to the present invention will now be described. The front axle suspension structure comprises a suspension bracket 1, a buffer block 2 and a fastening component, wherein the suspension bracket 1 is provided with two mounting grooves back to back, and a first through hole is formed along the center of each mounting groove; the buffer block 2 is provided with a second through hole; at least one buffer block 2 is arranged in each mounting groove, the buffer blocks 2 in each mounting groove are combined to form a buffer unit, and the height of each buffer unit exceeds the depth of the corresponding mounting groove; the fastening assembly comprises a bolt 4 penetrating through the second through hole and the first through hole and a fastening piece 3 matched with the bolt 4, and the buffer unit is fastened on two sides of the suspension bracket 1 through the bolt 4 and the fastening piece 3.
The utility model provides a front axle suspension structure, compared with the prior art, set up buffer block 2 in the both sides of suspension support 1 respectively, power transmission torsional vibration and the dead weight effect of itself are in the three ascending power of front axle suspension X, Y, Z, buffer block 2 only bears pressure, do not bear the pulling force, buffer block 2 in avoiding the front axle suspension receives the power transmission torsional vibration and the pulling force that dead weight produced of itself for a long time, buffer block 2 has been solved and has been drawn the power and produced the fracture, it is damaged, the problem of fracture or coming off, the problem of buffer block 2 inefficacy has been avoided, buffer block 2's life has been improved, front axle suspension structure buffering damping's performance has been guaranteed, make front axle assembly and frame keep elastic coupling, guarantee transmission's smooth operation, the travelling comfort that the guarantee was taken, positive effect has to the whole car NVH performance.
Wherein NVH is an English abbreviation of Noise, Vibration and Harshness (Noise, Vibration, Harshness), is a comprehensive problem for measuring the manufacturing quality of automobiles, and is one of the concerns of various automobile manufacturing enterprises and component enterprises in the international automobile industry. NVH performance has a significant impact on the comfort and quality of the finished vehicle.
In this embodiment, the coordinates of the front axle suspension X, Y, Z in three directions, the Z direction corresponds to the height direction of the entire vehicle, and the XY direction corresponds to the left and right and front and rear directions of the entire vehicle.
About the analysis of buffer block 2 atress, owing to set up two mounting grooves back to back, the tank bottom of two mounting grooves plays the effect of separation to the biography power of buffer block 2 of two components of a whole that can function independently, has avoided integral type buffer block 2 to suffer to tear the pulling force and the inefficacy problem that leads to, and buffer block 2 only bears pressure, can avoid damaging the inefficacy, improves life.
In the embodiment, the buffer block 2 is made of rubber, and has the function of buffering and absorbing vibration. The quantity of buffer block 2 can be two, and buffer block 2 plays the effect of vibration isolation energy-absorbing, and the size of two buffer block 2 can be different also can be the same, installs respectively in the mounting groove, and the degree of depth and the size of the mounting groove of adaptation also can be different. The key is that the bumper block 2, one or more, in each mounting slot requires a notch beyond the mounting slot. For example, when one buffer block 2 is placed in one mounting groove, one buffer block is a buffer unit, and the buffer unit exceeds the notch of the mounting groove; when placing two buffer blocks 2 in an installation groove, two buffer blocks are a buffer unit, and buffer block 2 in the at least outside will surpass the notch of installation groove, and when bolt 4 and fastener 3 compressed tightly buffer block 2, the notch of installation groove can not touch to guarantee buffer block 2's performance.
When the quantity of buffer block 2 was more than two, can be even or odd, for example place a buffer block 2 in the mounting groove, place two buffer blocks 2 in another mounting groove, the buffer block 2 combination in every mounting groove constitutes a buffer unit, and the key also lies in when bolt 4 and fastener 3 compress tightly buffer unit, can not touch the notch of mounting groove to guarantee buffer block 2's performance.
In a specific embodiment, a certain extrusion elasticity is required to be maintained between the side surface of the buffer block 2 and the inner wall of the mounting groove, that is, the buffer block 2 and the mounting groove are in an interference fit relationship, so as to ensure the vibration isolation performance of the buffer block 2.
As a specific implementation manner of the front axle suspension structure provided by the utility model, please refer to fig. 1 to 3, the front axle suspension structure still includes sleeve pipe 5, sleeve pipe 5 runs through second through-hole and first through-hole, and the buffer unit of the both ends of sleeve pipe 5 all do not bulge both sides, and bolt 4 wears to locate on sleeve pipe 5. Through sleeve pipe 5, with buffer block 2 series connection together, make buffer block 2 atress even, improve the effect of damping vibration isolation.
As a specific implementation manner of the embodiment of the present invention, please refer to fig. 1 to 3, one end of the sleeve 5 located on the nut of the bolt 4 is provided with a limiting retaining ring, the external dimension of the limiting retaining ring is greater than the external dimension of the nut of the bolt 4, and the buffering unit and the limiting retaining ring are in close contact with each other at the same side. Through the setting of spacing retaining ring, improve the area of contact between buffer block 2 and the limit structure, make the even atress of buffer block 2.
As a specific implementation manner of the embodiment of the present invention, referring to fig. 3, the end face dimension of the buffer unit contacting the limiting retainer ring is smaller than the external dimension of the limiting retainer ring. Aim at improves the area of contact between buffer block 2 and the limit structure, makes the even atress of buffer block 2.
As a specific implementation manner of the embodiment of the present invention, please refer to fig. 3, the sleeve 5 is in clearance fit with the first through hole, and the sleeve 5 is in interference fit with the second through hole. Specifically, sleeve 5 and suspension support 1 are not direct contact, realize elastic coupling through buffer block 2 between sleeve 5 and the suspension support 1, sleeve 5 and buffer block 2 interference hookup to make buffer block 2 atress even.
As a specific implementation manner of the embodiment of the present invention, please refer to fig. 3, the bolt 4 is in interference fit with the sleeve 5, so as to ensure that the bolt 4 is stressed uniformly at the central position.
As a specific implementation manner of the embodiment of the present invention, please refer to fig. 3, the buffer block 2 includes an elastic body and a skeleton embedded in the elastic body, and the skeleton is disposed near the side and the bottom of the elastic body. The setting of skeleton improves buffer block 2's rigidity, improves buffer block 2's life, reduces buffer block 2's damage.
As a specific implementation manner of the embodiment of the present invention, please refer to fig. 3, the buffer block 2 further has a flange extending into the first through hole, and the frame extends into the flange along with the shape. The part of buffer block 2 in extending to the first through-hole plays the effect of location to buffer block 2, has also prolonged the area of contact of buffer block 2 with sleeve 5 to when making the front axle move in whole car Y, Z direction, prevent sleeve 5 and suspension support 1 rigid contact.
As a specific implementation manner of the embodiment of the present invention, please refer to fig. 3, the fastening member 3 includes a spacing washer 31 closely contacted with the buffering unit and a fixing washer 32 tightly connected with the bolt 4.
