Reverse filling exhaust method of hydraulic pipeline of clutch booster

Abstract

The invention discloses a reverse filling exhaust method of a hydraulic pipeline of a clutch booster, comprising the following steps of: respectively connecting one end of each of two oil pipes to the inlet end and the outlet end of a manual oil pump, and connecting the other ends of two oil pipes to a deflation bolt of the booster and a vessel filled with clutch oil liquid; pressing the manual oil pump to enable the clutch oil liquid to enter the hydraulic pipeline of the clutch booster through the deflation bolt and fill oil liquid in the hydraulic pipeline of the clutch booster; in the process of filling the oil liquid, checking a liquid storage tank of the clutch booster; and stopping pumping oil and screwing the bleed bolt when the liquid level of the clutch reaches an upper line. Inthe reverse filling exhaust method, gas in the booster can be quickly exhausted by reversely filling oil liquid, the exhaust effect is remarkable, and bubbles do not basically exist in the hydraulic pipeline of the booster, The invention prevents the phenomena of incomplete separation, insusceptible gear, long reaction time and the like of the clutch, effectively protects the clutch, improves therunning safety of vehicles and has short exhaust time and low cost.

Description

technical field [0001] The invention relates to a method for discharging gas in a hydraulic pipeline of a clutch booster, in particular to a reverse filling and exhausting method for the hydraulic pipeline of the clutch booster. Background technique [0002] The clutches of large trucks mostly use clutch boosters (clutch boosters) in order to reduce the pedal force, make the operation light and flexible, and shorten the reaction time. The common basic form of the booster is the hydraulically controlled air-assisted type, referred to as the hydraulically controlled pneumatic type. When the piston of the clutch master cylinder moves, the clutch fluid is pushed to flow in the pipeline to generate hydraulic booster, which makes the pedal action light and flexible. Such as the clutch booster disclosed in the utility model patent known as "automotive clutch booster pump" with the patent No. ZL200620029558. , spring (8), leather cup (9), piston rod (10), valve plate (11), small pi...

AI Technical Summary

Problems solved by technology

[0004] Because the oil intake of the hydraulic pipeline is after the foot releases the clutch pedal, under the action of the clutch master cylinder piston return spring, the piston moves up and the internal volume of the clutch master cylinder expands to generate negative pressure to absorb oil, and the exhaust is initially exhausted when the vacuum degree is not large. stage, the oil absorption is small, the exhaust effect is poor, and it is difficult to discharge all or most of the gas; moreover, the exhaust time is long, sometimes the entire exhaust process takes several hours to complete, and a lot of clutch oil is wasted. Correspondingly increased exhaust costs
