Problems solved by technology

Now the joint height of the separation finger of the product can be guaranteed to be L±1, but it is difficult to guarantee the runout of 0.6, which can only be solved by calibration. The existing method is that the operator detects the data according to the dial indicator, and then takes a reference finger siz

Example Embodiment

[0028] In this embodiment, the method for correcting and detecting the jump of the disengagement finger of the automobile diaphragm spring clutch is as follows: First, through the product and tolerance design, control the engagement height of the disengagement finger of the diaphragm spring clutch within the range of (L-1)±1; Detection, the correction and detection is to use the servo motor to drive the screw jack to push the separation direction of the diaphragm spring clutch upwards, so that the separation finger is deformed, and through the deformation, the separation finger engagement height reaches the specified size range to ensure The separation means the runout is within the specified tolerance range, where L is the standard value of the separation means joint height.

[0029] In this embodiment, the method for correcting and detecting the beating of the release finger of the automobile diaphragm spring clutch is as follows:

Abstract

The invention discloses a separation finger jumping correction and detection method for an automobile diaphragm spring clutch, which is characterized by comprising the following steps of: firstly, controlling the connection height of a separation finger of the diaphragm spring clutch in the range of (L-1) plus and minus 1 by the product and tolerance design; and then carrying out correction and detection, wherein in the correcting and detecting process, a jack screw is driven by a servo motor, the separation finger of the diaphragm spring clutch is jacked upward to be deformed, the connection height of the separation finger reaches the specified size range by the deformation, the separation finger is ensured to jump in the specified tolerance range and L represents a separation finger connection height standard value. According to the invention, the requirement on the jumping of the separation finger of the diaphragm spring clutch can be met and reliable data of each separation finger connection height is provided.

Description

technical field [0001] The invention relates to a test method for correcting and detecting the beating of the disengaging finger of a diaphragm spring clutch of an automobile. Background technique [0002] The diaphragm spring clutch is a clutch made of a diaphragm spring instead of a general coil spring and a release lever mechanism. The diaphragm spring clutch has many advantages: First, because the diaphragm spring has nonlinear characteristics, it can be designed as a friction plate After wear and tear, the spring pressure can remain almost unchanged, and the pedal force when disengaging the clutch can be reduced, making the operation easy; secondly, the diaphragm spring itself also acts as a compression spring and a disengaging lever, which greatly simplifies the structure of the clutch. The number of parts is reduced, the mass is reduced and its axial dimension is significantly shortened; in addition, because the diaphragm spring and the pressure plate are in contact w...
