Technical Field
The application relates to the technical field of automobile performance, in particular to a method for solving friction order jitter and a clutch.
Background
At present, jitter evaluation is an important evaluation index in the driving performance of the whole vehicle and is an important basis for determining the driving quality. In the evaluation system of the driving performance of the whole vehicle, the vibration is essentially that after a transmission system of the whole vehicle is stimulated by an excitation source, resonance is generated near the natural frequency of the transmission system. The larger the vibration amplitude of the excitation source is, the closer the frequency is to the resonance frequency of the whole vehicle, the larger the resonance amplitude of the whole vehicle is, the more obvious the vibration feeling is, and the worse the corresponding driving quality is. The specific performance of the vehicle shaking is as follows: high-frequency fluctuation of real-time parameters such as vehicle acceleration, transmission torque of a gearbox, input shaft rotation speed, driving pressure and the like.
The whole vehicle transmission system comprises a gearbox system, and the most critical component in the gearbox system for influencing the shaking is a clutch. During the whole vehicle driving performance test, the clutch usually generates a slip order of shake. The formation of moir order jitter requires two conditions and unacceptable moir order jitter tends to occur if and only if the following two conditions are met simultaneously. Specifically, the two conditions are that (1) the frequency corresponding to the rotating speed of the clutch sliding friction (the rotating speed difference value of the input end and the output end of the sliding friction finger clutch) is close to or overlapped with the frequency of the whole vehicle transmission system; (2) the excitation amplitude of the sliding friction excitation source is large, so that the resonance amplitude of a transmission system of the whole vehicle is large.
An effective fundamental method for thoroughly solving the problem of the slippage order jitter is not provided all the time, and particularly, once the whole vehicle with the double-clutch mechanism generates unacceptable slippage order jitter, the driving quality of the whole vehicle is seriously influenced.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the respective embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, the present application discloses an embodiment of a method for solving the slip order judder, which is used for manufacturing a clutch and can reduce the judder of the slip order. The clutch mainly comprises a steel sheet 3 and a friction plate 4, wherein the steel sheet 3 is made of metal materials, the manufacturing process is mature, and the thickness variation is basically ignored; the friction plate 4 is a mixture of metal and non-metal materials, has a larger deformation tendency, and has larger thickness dispersion. According to the method for solving the sliding friction order jitter, the purpose of weakening or eliminating the sliding friction order jitter is achieved through the thickness dispersion difference of the friction plates 4 which are regularly arranged.
The method for solving the problem of the sliding friction order jitter comprises the following steps:
s1: a mold for producing the friction plate 4 is made, which can mark the friction plate 4.
S2: a batch of friction plates 4 with mark points on the outer surface are produced.
S3: the friction plate 4 is measured to obtain the number n of high points 41 of the thickness distribution of the friction plate 4. Specifically, one friction plate 4 is selected for measurement, and since the friction plates 4 in the batch are manufactured in the same mold under the same production conditions, the number and the positions of the high points 41 of all the friction plates 4 are basically the same. The number n of the high points 41 of the batch can be known after the number n of the high points 41 of the thickness of one friction plate 4 is measured.
S4: when the clutch is assembled and m friction plates 4 are installed in an overlapping mode, according to the known number n of the high points 41 and the known number m of the friction plates 4, the mark points of all the friction plates 4 are uniformly distributed along the total overlapping axis of the friction plates 4 (the central axis formed by overlapping all the friction plates). Because the mould is produced in batch, the relative positions of the high points and the mark points of the friction plates produced in batch are fixed, namely the high points of all the friction plates 4 are uniformly distributed along the total superposition axis of the friction plates 4.
The method for solving the friction slip order jitter is to regularly and uniformly distribute the thickness high points 41 of all the friction plates 4 in the circumferential direction to weaken or eliminate the thickness high points 41 of a single friction plate 4 and the thickness high points 41 of a plurality of friction plates 4 which are irregularly arranged, namely, the excitation amplitude of a friction slip excitation source is reduced or eliminated.
Specifically, as shown in fig. 2, the top view of the friction plate shows that the thickness of the friction plate 4 is measured at uniform intervals along the circumference, and it can be seen that the circumferential thickness distribution of the friction plate 4 is deviated, and the trend of height always appears. And the friction plates are produced in batches, so that the thickness distribution trend of the friction plates has certain regularity and consistency. After a certain mature and mass-produced friction plate is subjected to batch measurement and analysis, the circumferential thickness distribution of the friction plate is found to always present two high points 41 (the high points in the present document refer to the relatively high points of the thickness, and will not be described in detail later), as shown in fig. 3.
It should be noted that, due to the characteristics of the manufacturing process of the friction plate, when the number of the high points 41 is greater than or equal to 2, the high points 41 are uniformly distributed along the circumference of the friction plate 4.
When the friction plate 4 is assembled, if the high points of the friction plate are exactly and completely overlapped, the total thickness of the friction plate 4 also presents similar two high point distribution, the situation is shown as a dotted line diagram in fig. 5, in the actual production, the space clamped by the steel sheets 3 matched with the friction plate 4 cannot be perfectly parallel, and a wedge-shaped trend (shown in fig. 4) always appears, in this case, every time the friction plate 4 relatively rotates for one circle relative to the steel sheets 3, the two high points respectively pass through the narrowest position of the wedge-shaped space once to form one fluctuation, and because once each sliding friction, two fluctuations appear, so-called second-order sliding friction order jitter is formed. If no high point is present in the total thickness of the friction plates 4 after the friction plates 4 are assembled, as shown in the solid line diagram in fig. 5, in this case, no high point excitation occurs every time the friction plates 4 rotate relative to the steel plates 3, and no fluctuation occurs.
As shown in fig. 5, when the friction plates 4 are assembled, if four friction plates 4 need to be assembled, if the two high points are sequentially spaced by 45 degrees, then a total of 4 × 2=8 high points are uniformly distributed on the circumference, and the total thickness of the friction plates 4 does not exhibit similar two high points, but exhibits a relatively uniform thickness distribution, and in this case, there are no high points, and therefore, slipping order jitter does not occur. Actually, the dashed line diagram in fig. 5 is the worst case, the solid line diagram in fig. 5 is the most ideal case, and most cases are between the dashed line diagram and the solid line diagram in fig. 5 at present, so that the slippage order jitter always exists. The method for solving the problem of the friction-sliding order jitter aims to ensure that the distribution of the thickness high points of the friction plate 4 after being installed is as close as possible to the solid line graph in the graph 5.
In one embodiment, the marker points of the m friction plates 4 are arranged at equal angular intervals along the total axis of superposition of the friction plates 4.
In one embodiment, in step S4, the mark points of two adjacent friction plates 4 are staggered by an angle θ;
wherein the number of friction plates 4 is m, and the number of high points 41 of each friction plate 4 is n.
Further, m is equal to 4, n is equal to 2, and the mark points of two adjacent friction plates 4 are spaced by 45 ° when calculated by the above formula.
In one embodiment, the mark points are clearly visible on the friction plate 4, and have a certain degree of identification. The mould is internally provided with a fine ink channel, the mark points are ink points, when the friction plate 4 is manufactured through the mould, ink is injected into the ink channel, and the ink points which are clearly visible are formed on the outer surface of the friction plate 4.
In other embodiments, the mark point on the cavity surface of the mold may be in a triangular shape, a quadrangular shape, or the like, which is obtained by other surface treatment processes.
The application also discloses a clutch using the method for solving the sliding friction order jitter, the clutch comprises n friction plates 4 and n +1 steel sheets 3 which are arranged in a staggered mode, the input end of the clutch is connected with all the steel sheets 3, the output end of the clutch is connected with all the friction plates 4, and any two adjacent steel sheets 3 are spaced by one friction plate 4; the axes of all the steel sheets 3 and the friction plates 4 are coincident.
When no external force is applied, the steel sheet 3 and the friction plate 4 are spaced from each other; when external force is applied, the steel sheet 3 and the friction plate 4 are mutually attached; the mark points of the m friction plates 4 are uniformly distributed along the total superposition axis of the friction plates 4. Because the mold is produced in batch, the relative positions of the high points and the mark points of the friction plates produced in batch are fixed, the mark points are uniformly distributed along the total superposition axis, and the high points representing the friction plates are also uniformly distributed along the total superposition axis.
With respect to the clutch, in one embodiment, the mark points of the m friction plates 4 are arranged at equal angular intervals along the total axis of superposition of the friction plates 4. The staggered angle of the mark points of two adjacent friction plates 4 is theta;
in one embodiment, m is equal to 4, n is equal to 2, and the mark points of two adjacent friction plates 4 are separated by an angle of 45 °.
In one embodiment, the marker points of the mold cavity surface are ink dots.
Regarding the clutch, in one embodiment, the clutch is a multi-plate type double clutch, the steel plate 3 is divided into an outer steel plate 3 and an inner steel plate 3, and the friction plate 4 is divided into an inner friction plate 4 and an outer friction plate 4. The outer steel sheets 3 and the outer friction sheets 4 are arranged in a crossed mode, the inner steel sheets 3 and the inner friction sheets 4 are arranged in a crossed mode at intervals, and the axes of the outer steel sheets 3, the outer friction sheets 4, the inner steel sheets 3 and the inner friction sheets 4 are overlapped. The staggered angle of the mark points of two adjacent outer friction plates 4 and the staggered angle of the mark points of two adjacent inner friction plates 4 are independently calculated separately.
Specifically, the number of the inner clutch friction plates is 4, each friction plate has 2 high points, and the mark points of the friction plates are sequentially spaced by an angle of 360 °/(4 × 2) =45 °. The number of the outer clutch friction plates is 3, and each friction plate has 2 high points, and the mark points of the friction plates are sequentially spaced at an angle of 360 degrees/(3 x 2) =60 degrees.
According to the method and the clutch for solving the sliding friction order jitter, the clutch mainly comprises the steel sheet 3 and the friction plate 4, the steel sheet 3 is made of metal, the manufacturing process is mature, and the thickness dispersion is basically ignored; the friction plate 4 is a mixture of metal and non-metal materials, and has a larger deformation tendency and a larger thickness variation.
