Description
Technical Field
The invention belongs to the technical field of clutches.
Background
With the continuous development of the automobile industry, automobiles are more and more popular, and people can also feel safe and comfortable when taking the automobiles
The increasingly higher requirements are put forward, and the quality of the automobile clutch which is used as an important part for transmitting and cutting off power transmission of the automobile directly influences the safety and comfort of the automobile.
The quality performance of the clutch has high requirements on details in the process of transportation and installation of the clutch besides the difference of the product quality of the clutch. The invention discloses a clutch cover assembly, which aims to avoid the direct influence of misoperation in the installation process of a clutch cover assembly on the service life of the clutch, thereby prolonging the service life of the clutch to the maximum extent. The assembly is illustrated in the following figure, the clutch cover and the clutch pressure plate are connected by means of the transmission plate and the bolt-pressure plate. When the clutch is installed, 9 installation bolts are required to be pre-twisted and connected in a point-to-point mode, but the clutch pressure plate still inclines on the premise that the bolts are tightened in sequence, and certain influence is generated on the use of the clutch.
The disadvantages of the prior first technique are: when the clutch mounting bolt is screwed down, point-to-point connection is needed, the pressure plate needs to be improved by 10mm from a free position to a working position (different thicknesses of driven plate assemblies exist), after the No. 1 bolt is pre-tightened, the No. 5 bolt needs to be pre-tightened, and after the No. 2 bolt is pre-tightened, the No. 7 bolt needs to be pre-tightened, so that the process is repeated until all the bolts are fully tightened. The workload is large, and the consumed working hours are long. When violent operation occurs, the bolt is directly tightened, the inclination of the point position pressure plate is 10mm, and the service life of the clutch is influenced.
The second prior art has the following defects: although the purpose of reducing the tilting amount of the pressure plate can be achieved by adding the gaskets below the bolts of the clutch pressure plate, the method needs more gaskets, basically needs 3 or 4 gaskets, and has the following disadvantages:
1. the process is cumbersome due to the large number of shims to install and remove.
2. If the gasket is not completely removed, or left in the flywheel housing of the engine, or left in the clutch, the gasket may impair the proper operation of other components due to centrifugal force when the engine or clutch is rotating.
3. The installation position of the gasket is limited, and the gasket is only allowed to be installed at the position of the pressure plate bolt, so that the distribution can be only 90 degrees or 120 degrees in an intermittent mode. The supporting position can not be supported for the whole week, and the diaphragm spring atress is uneven, and the deflection of diaphragm spring is greater than the position deflection that does not have the gasket in gasket position, influences clutch assembly's flexography, and the influence of different deformations takes place for installation bolt hole or connection size, probably leads to clutch installation difficulty or influences diaphragm spring life.

Detailed Description
The method comprises the following steps:
firstly, the free-state clutch assembly is placed on a clamping platform 11, namely, a diaphragm spring 9 is contacted with a clutch cover 8 (see figure 1).
And secondly, applying force to bolts I-IX (see figure 2), adjusting the clutch assembly to the mounting position, wherein the distance between the flange surface of the clutch pressure plate 10 and the flange surface of the clutch cover 8 is 10mm, namely, the diaphragm spring 9 and the clutch cover 8 are completely separated, and the gap is about 4mm (see figure 3).
And step three, the auxiliary supporting ring handle 4 is held by hand, supports against the clutch cover 8 through the limiting pin I2 and is aligned with the supporting rivet 12, the supporting ring 3 is placed in a gap between the clutch cover 8 and the diaphragm spring 9, the notch 7 is compressed until the supporting ring can completely fall into the gap, the handle 4 is loosened and is aligned with the bolt-pressing plate 13, the limiting pin II5 supports against the clutch cover 8, and the auxiliary supporting ring returns to a free state (see figure 4).
And step four, unloading the pressure applied at the bolts I-IX, recovering the clutch to a free state, clamping the auxiliary supporting ring 3 by the clutch cover 8 and the diaphragm spring 9, and finishing the installation.
The structure of the auxiliary supporting ring 3 of the invention is as follows: the two ends of the annular ring 31 are respectively and horizontally folded inwards to form a limit pin bending I1 and a limit pin bending II6, the inward folding distances of the limit pin bending I1 and the limit pin bending II6 are equal, the end parts of the limit pin bending I1 and the limit pin bending II6 are respectively and vertically provided with a limit pin I2 and a limit pin II5, and the horizontal position of the top end of the limit pin II5 is the handle 4.
The invention is described in further detail below with reference to the accompanying drawings:
firstly, the clutch assembly is loaded, and the clutch assembly is adjusted to the installation position, namely, the diaphragm spring 8 is completely separated from the clutch cover 4.
And step two, placing the auxiliary supporting ring 3 in the gap between the diaphragm spring 8 and the clutch cover 4.
And thirdly, propping against the clutch cover 4 through the limiting pin 1, holding the handle 2 to compress the auxiliary supporting ring 3 until the auxiliary supporting ring can completely fall into the gap, loosening the handle 2 and recovering the auxiliary supporting ring 3 to be in a free state.
And step four, unloading the clutch assembly, and recovering the clutch to a free state.
And step five, according to the installation principle of the clutch, when the clutch cover assembly clamps the driven plate assembly, the clutch pressure plate 9 is lifted by 10 mm.
Step six, the diaphragm spring is lowered by 4mm at the position of the auxiliary diameter phi 180mm according to the lever ratio 62.5 ÷ 25= 2.5.
And seventhly, if the diameter of the auxiliary supporting ring 3 exceeds phi 4mm, under the limiting action of the auxiliary supporting ring 3, the lifting distance of the clutch pressure plate 9 exceeds 10mm, and the cover assembly cannot clamp the driven plate assembly, so that the diameter of a steel wire of the auxiliary supporting ring 3 cannot be larger than 4 mm.
Step eight, when the theoretical value of the diameter of the steel wire of the auxiliary supporting ring 3 is 4mm, the distance between the diaphragm spring 8 and the clutch cover 4 is 4mm at the position (phi 180 mm) of the auxiliary supporting in the installation state.
And step nine, considering the dimensional tolerance of the parts, determining the diameter of the auxiliary supporting ring as phi 3mm on the premise that the clearance of the auxiliary supporting ring cannot exceed 4mm, wherein under the theoretical size, the lever ratio is 62.5 ÷ 25=2.5, the clutch pressure plate 9 is lifted by 7.5mm, and a lifting margin of 2.5mm is also tightened through a clutch mounting bolt.
Step ten, based on the theory, under the action of bolt tightening, the stroke of the clutch pressure plate 9 is 2.5mm, which is reduced by 7.5mm compared with 10mm in a free state.
Step eleven, due to the limiting effect of the auxiliary supporting ring 5, the inclination amount of the pressure plate is reduced to 2.5mm from the maximum 10mm, and the pressure plate is supported for 360 degrees in a whole circle, so that the deformation amounts of the diaphragm spring 8 and the clutch cover 4 are uniform.
Step twelve, after the clutch is installed, the diaphragm spring 8 is completely separated from the clutch cover 4; the stop pin 1 is abutted against the clutch cover 4, the handle 2 is held to compress the auxiliary support ring 3, and the auxiliary support ring 3 is taken out.
The principle is explained as follows:
(1) according to the principle of clutch installation, when the clutch cover assembly clamps the driven plate assembly, the clutch pressure plate 10 will be lifted by 10mm (in this case, the clamping thickness is 10mm when the driven plate assembly is installed).
(2) According to the lever ratio 2.5 (62.5/25), the diaphragm spring is lowered by 4mm in the position shown by 62.5 mm.
(3) If the diameter of the auxiliary supporting ring 3 exceeds phi 4mm, the lifting distance of the clutch pressure plate 10 exceeds 10mm under the limiting action of the auxiliary supporting ring 3, the cover assembly cannot clamp the driven plate assembly, and therefore the diameter of a steel wire of the auxiliary supporting ring 3 cannot be larger than 4 mm.
4 the theoretical value of the wire diameter of the auxiliary support ring 3 is 4mm, the distance of the diaphragm spring 9 from the clutch cover 8 is 4mm at the position (62.5 mm) of the auxiliary support in the mounted state.
(5) Considering the dimensional tolerance of the parts, on the premise of designing a gap which can not exceed 4mm, the diameter of the auxiliary supporting ring is determined to be phi 3mm, and under the theoretical size, the lever ratio is 62.5/25=2.5, the clutch pressure plate 10 is lifted by 7.5mm, and a lifting allowance of 2.5mm is also arranged, and the allowance is tightened through a clutch mounting bolt.
(6) From the theory above, under the effect of bolt tightening, the stroke of clutch pressure plate 10 is 2.5mm, and with 10mm under the free state, has reduced 7.5 mm's stroke.
(7) Due to the limiting effect of the auxiliary supporting ring 3, the tilting amount of the pressure plate is reduced to 2.5mm from the maximum 10mm, and the pressure plate is supported for 360 degrees in a whole circle, so that the deformation amounts of the diaphragm spring 9 and the clutch cover 8 are uniform.
(8) After the clutch is installed, the diaphragm spring 9 is completely separated from the clutch cover 8. The auxiliary support ring 3 is compressed through the gap 7 by holding the handle 4 by abutting against the clutch cover 8 through the limit pin I2 and the limit pin II5, and the auxiliary support ring 3 is taken out.
