[0001] The utility model belongs to the technical field of clutch separation stroke measurement, and in particular relates to a vehicle clutch separation stroke measurement device and a vehicle clutch. Background Art

[0002] At present, when judging whether there is a fault in the vehicle clutch function, it is first necessary to confirm the disengagement stroke of the clutch when it is working. Due to the limited space in the clutch working cavity and the small observation window on the clutch housing, conventional tools and devices cannot be used. Therefore, there is no device that can quickly, conveniently and accurately measure the clutch disengagement stroke. Every time a clutch failure is suspected, it is necessary to remove the gearbox and replace a new clutch to see whether the fault can be eliminated to infer whether the clutch is normal. The entire operation process is not only cumbersome, but also time-consuming and labor-intensive. Utility Model Content

[0003] The utility model provides a vehicle clutch separation stroke measuring device and a vehicle clutch, which are used to solve the technical defects in the prior art that there is no tool specifically for measuring the clutch separation stroke, resulting in the need to disassemble the clutch when judging a clutch failure, which is not only cumbersome but also time-consuming and labor-intensive.

[0042] The present embodiment is described in detail below with reference to the accompanying drawings.

[0043] This embodiment provides a vehicle clutch release stroke measuring device and a vehicle clutch.

[0044] like Figure 1-Figure 4 As shown, in the first aspect, this embodiment provides a vehicle clutch release stroke measuring device.

[0045] Embodiment 1:

[0046] A device for measuring the release stroke of an automobile clutch comprises a measuring member 4; a sliding member 3, which is slidably connected to the measuring member 4; a fastener 2, one end of which is connected to the sliding member 3 and the other end of which is against the surface of the measuring member 4, and is used to enhance the friction between the sliding member 3 and the measuring member 4, ensuring that the measuring member 4 and the sliding member 3 can cooperate smoothly and reliably; an adsorption member 1, which is installed on one end of the sliding member 3 away from the measuring member 4, and the adsorption member 1 is used to fix the sliding member 3 on the release bearing. Taking commercial vehicles as an example, when measuring the clutch release stroke, the measuring device is adsorbed on the pull ear of the release bearing through the clutch observation window using the adsorption part 1, and the sliding measuring part 4 is made so that its arc surface is attached to the end face of the gearbox. At this time, the value of the scale line on the measuring part 4 is recorded, and the clutch operating system is operated by stepping on the clutch pedal in the cab. During this process, the clutch operating system pulls the clutch release bearing, and the pull ear of the release bearing drives the sliding part 3 to slide on the measuring part 4. Then, the value of the scale line on the measuring part 4 after sliding is read, and the difference between the scale line value recorded for the first time and the scale line value recorded for the second time is calculated. The difference between the two is the separation stroke of the clutch operating system. If the stroke meets the clutch use requirements, the fault comes from the clutch itself, otherwise it comes from the clutch operating system.

[0047] In this embodiment, a mounting plate is provided on one end of the sliding member 3 and the measuring member 4 for sliding connection, and the fasteners 2 are symmetrically arranged on the mounting plate. Figure 1-Figure 4 It can be seen that the mounting plate is a transparent mounting plate, which does not affect the observation of the scale lines on the measuring piece 4. During the measurement process, in order to ensure the stability of the measuring piece 4, a groove is provided at one end of the sliding piece 3 and the measuring piece 4 where the sliding piece 3 is slidably connected. The measuring piece 4 is located in the groove and can slide in the groove. Secondly, the mounting plate is set at the top of the groove and is located above the measuring piece 4 to block the opening of the groove. The end of the fastener 2 is against the top of the measuring piece 4, so that the mounting plate can position the measuring piece 4, thereby enhancing the stability between the two and reducing the measurement error caused by the position offset of the sliding piece 3 during the measurement process.

[0048] In the present embodiment, the sliding member 3 is a brass slider. Since brass has good lubricity and a low friction coefficient, it can reduce friction when it is in sliding contact with the measuring member 4, thereby ensuring smooth sliding, reducing energy loss, and extending the service life of the measuring member 4. In the present embodiment, the sliding member 3 is preferably L-shaped. On the one hand, one end of the sliding member 3 is slidably connected to the measuring member 4, and the other end is fixed to the pull ear of the release bearing through the adsorption member 1, so that the sliding member 3 can slide smoothly. On the other hand, since the pull ear of the release bearing and the end face of the gearbox are axially perpendicular, the L-shaped structure is selected to satisfy the positional relationship between the two.

[0049] In this embodiment, the fastener 2 is axially perpendicular to the measuring member 4 and can provide a stable support and locking mechanism, which helps to reduce the shaking or deviation of the measuring member 4 during the sliding process, thereby ensuring the accuracy and reliability of the measurement.

[0050] In this embodiment, the fastener 2 is a spring, and is preferably a wave spring. The wave spring can effectively absorb and disperse vibration and impact force, so that the sliding member 3 runs more smoothly and reduces noise and vibration amplitude.

[0051] In this embodiment, the adsorption member 1 is a strong magnet. By utilizing the strong adsorption force of the strong magnet, no additional tools or clamps are needed when fixing the sliding member 3, thereby simplifying the operation process.

[0052] In this embodiment, the measuring piece 4 is preferably a ruler, and the end of the ruler has an arc surface, which can be evenly stressed during the measurement process. Since the length or distance scale is directly marked on the ruler, the measurement result can be read directly without complicated calculations or conversions, making the measurement process faster and simpler.

[0053] Attach the brass slider to the lug on one side of the release bearing. Since there are two magnetic surfaces, it can be kept parallel to the lug. The scale can slide freely in the brass slider. Slide the scale until the arc end contacts the side wall of the gearbox. The entire installation process is completed. When starting to measure, record the initial position first, then step on the clutch pedal. The clutch operating system will drive the split shaft bearing to move and drive the brass slider together. Since the scale contacts the side wall of the gearbox to limit its movement, the brass slider will slide on the scale, thereby reading the moving distance of the release bearing. This sliding distance is the clutch separation stroke.

[0054] Embodiment 2:

[0055] The difference from the first embodiment is that, in this embodiment, the sliding member 3 can be a T-shaped structure, the groove is opened on the horizontal end of the T-shaped structure, and the adsorption member 1 is installed on the vertical end of the T-shaped structure. The design of the T-shaped structure makes the sliding member 3 have better stability during the sliding process. Since the vertical end increases the support area of ​​the structure, the sliding member 3 is less likely to tilt or shake when moving, thereby ensuring the accuracy and reliability of the operation; in addition, the measuring member 4 can be a digital ruler, which usually has a high measurement accuracy and can be accurate to several decimal places, even up to the micron level. This high-precision measurement can improve product quality and work efficiency; secondly, the digital ruler directly displays the measurement results in digital form, avoiding the need for manual reading and interpretation, reducing the possibility of human errors, and direct digital display also makes the measurement results more intuitive and easy to record, thereby improving the efficiency of data processing.

[0056] In a second aspect, this embodiment provides a vehicle clutch, such as Figure 5 As shown, it includes a vehicle clutch body, and the separation stroke of the vehicle clutch body is measured using the measuring device as described above.

[0057] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
