Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic clutches, in particular to a hydraulic clutch exhaust device. Background Art

[0002] A hydraulic clutch is a device that uses hydraulic principles to achieve clutch functions. It is commonly used in automobiles, motorcycles, and some mechanical equipment to control the transmission and cutoff of power. During the normal operation of a hydraulic clutch, the movement of the liquid medium (usually hydraulic oil) inside the clutch is crucial. However, in a hydraulic system, due to various reasons (such as temperature changes in the liquid, bubble formation in the system, aging of seals, etc.), gas may be mixed into the hydraulic oil. The presence of this gas will affect the performance of the hydraulic system and needs to be discharged. Therefore, a hydraulic clutch exhaust device is required.

[0003] The traditional hydraulic clutch exhaust device requires two people to work together. One person repeatedly steps on the clutch pedal, and the other person unscrews the exhaust bolt to bleed the air and observe until no more gas is discharged from the bleed screw. This operation method not only has poor exhaust effect, but also easily causes some gas to still be contained in the hydraulic clutch. It also takes a lot of time and reduces work efficiency. In addition, during the exhaust process, some hydraulic oil will be discharged from the exhaust screw along with the gas, which easily causes waste of hydraulic oil. Utility Model Content
