[0001] The utility model relates to the technical field of tension wheels, in particular to a combined automatic tension wheel. Background Art

[0002] In the engine assembly, the automatic tensioner is a very important component. It is responsible for ensuring that the timing chain or belt maintains proper tension to ensure the normal operation of the engine. At the same time, when the engine is running, the automatic tensioner will automatically adjust the tension as needed to adapt to the extension and contraction of the chain or belt.

[0003] In the prior art, the automatic tensioner is fixed to the engine compartment, and when the belt is connected to start the engine, the automatic tensioner is generally used in conjunction with an idler pulley to achieve the purpose of transmitting power and changing the direction of the belt. However, considering that the internal components of the engine compartment are installed in a relatively compact manner, due to space limitations, in the actual installation of the tensioner and idler pulley, there is a problem of insufficient engine space and inability to add bolt fixing points for fixed installation operations. Therefore, a combined automatic tensioner is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a combined automatic tensioner to solve the problem in the prior art proposed in the above background technology that when the automatic tensioner is fixedly installed, there is insufficient engine space and it is impossible to add bolt fixing points for fixed installation operations.

[0017] See also Figure 1-2 , the utility model provides a technical solution:

[0018] A combined automatic tensioner comprises a positioning base 1, a combined collar 2 is sleeved on the outside of the positioning base 1, a fixed bracket 3 is fixedly connected to the upper left position of the combined collar 2, a semicircular notch 4 is opened on one side of the front of the fixed bracket 3, a first fixed fulcrum 5 is arranged in the middle of the semicircular notch 4, a reinforcing rib 6 is fixedly connected to the outside of the first fixed fulcrum 5, a second fixed fulcrum 7 is arranged on the other side of the front of the fixed bracket 3, a tensioner body 9 is arranged in front of the second fixed fulcrum 7, an idler body 10 is arranged in front of the first fixed fulcrum 5, a fastening clamp 11 is arranged in the middle of the front of the fixed bracket 3, and the fastening clamp 11 is fixedly connected to the fixed bracket 3 by a fastening bolt 15.

[0019] like Figure 1 and Figure 2The upper half of the fixed bracket 3 shown is arranged in a "V"-shaped structure, and bolt fixing circular holes 8 are respectively opened at the lower left and upper positions of the fixed bracket 3. After ensuring that the fixed bracket 3 is fixed to the corresponding position, the fixed bracket 3 and the automobile engine compartment can be fixedly connected at the same time by bolt fixings passing through the bolt fixing circular holes 8, so that the fixed bracket 3 can be quickly fixed and installed; the fixed bracket 3 is fixedly connected to the reinforcing ribs 6, and the reinforcing ribs 6 are arranged in a ring array structure along the center point of the first fixed fulcrum 5. By arranging a plurality of reinforcing ribs 6 on the outside of the first fixed fulcrum 5, this structural arrangement can improve the overall strength of the first fixed fulcrum 5 so that it can be stably connected with the idler wheel body 10; a short connecting rod 12 is fixedly connected to one side position of the fastening clamp 11, and a first retaining ring 13 is fixedly connected to the short connecting rod 12 on the side end away from the fastening clamp 11. The first retaining ring 13 and the first fixed fulcrum 5 are coaxially arranged, and the other side of the fastening clamp 11 A second snap ring 14 is fixedly connected, and the second snap ring 14 and the second fixed fulcrum 7 are coaxially arranged. Before assembling the tension wheel and the idler wheel, the second snap ring 14 and the first snap ring 13 can be installed to the edge positions close to the first fixed fulcrum 5 and the second fixed fulcrum 7 respectively by fastening the clamp 11 and the fixed connection of the fixed bracket 3. When it is necessary to fix the tension wheel and the idler wheel on the fixed bracket 3 respectively, the second snap ring 14 and the first snap ring 13 arranged at the edge positions of the first fixed fulcrum 5 and the second fixed fulcrum 7 will play a guiding installation role for the fixing of the tension wheel and the idler wheel, so that both can be accurately installed; the center point of the positioning base 1 and the center point of the combined ring 2 are overlapped, and the connection between the combined ring 2 and the fixed bracket 3 constitutes a "V"-shaped clamping groove structure. By setting the fixed bracket 3, this setting will facilitate the integrated combination installation of the tension wheel body 9 and the idler wheel body 10, so as to facilitate subsequent integrated installation.

[0020] Working process: Before using the combined automatic tensioner, the tensioner body 9 can be installed on the second fixed fulcrum 7 and the idler body 10 can be installed on the first fixed fulcrum 5 respectively under the auxiliary limiting action of the first retaining ring 13 and the second retaining ring 14, and fastened and limited respectively by fasteners. When the entire combined automatic tensioner is fixedly assembled in the engine compartment of the automobile, the staff first removes the fastening bolts 15 from the fixing bracket 3, so that the first retaining ring 13 and the second retaining ring 14 are also removed. After the bolt fixing circular hole 8 and the corresponding assembly hole groove are one-to-one corresponding, the fixing bracket 3 can be quickly fixed to the corresponding position by assembling the bolt fixing parts, so that the entire combined automatic tensioner can use the independent bracket structure composed of the first fixed fulcrum 5, the second fixed fulcrum 7, the fixing bracket 3 and the combined collar 2 to fix the idler and the tensioner, so that it can be subsequently assembled into the engine compartment of the automobile as a whole.
