Summary of the invention
In order to guarantee that heavy duty truck is when power-transfer clutch thoroughly separates, change-speed box carries out shifting again and handles, thereby reduce the transmission gear cause because of human element and synchro premature wear and damage, alleviate the manipulation strength of chaufeur, effectively improve the smooth gear shifting of many gears change-speed box, the utility model provides a kind of heavy duty truck clutch speed-changing control system of improving structure.
Concrete technical solution is as follows:
A kind of heavy duty truck clutch speed-changing control system comprises clutch operation and transmission control, clutch pedal 3 middle parts of described clutch operation are connecting the push rod place of clutch master cylinder 4, the oil inlet of clutch master cylinder 4 is being communicated with the oil outlet of clutch oil can 2, and the oil outlet of clutch master cylinder 4 is being communicated with the oil inlet of clutch servo-unit by clutch oil pipe 13; The control mouth of the high to low gear preselector valve 1 of described transmission control is respectively two-way, the arm of wherein leading up to is being communicated with the air extractor duct of air receiver 8, improvement is: also comprise control cock 6, described control cock 6 is a switch valve, its first air extractor duct is corresponding with the caging bolt of clutch pedal 3 lower ends, second air extractor duct is being communicated with the import that partly keeps off odd-side relay valve 11 by pipeline, the outlet that partly keeps off odd-side relay valve 11 divides two branch roads, one branch road is communicated with high to low gear preselector valve 1, two branch road and is being communicated with supply power assisted gearshift device 12; The admission port of described control cock 6 is being communicated with pipeline between high to low gear preselector valve 1 and the air receiver 8 by three-way pipe.
The utility model is compared with prior art products and is had the advantage of following aspect: by increasing control cock, guaranteed when power-transfer clutch thoroughly separates, change-speed box carries out shifting again and handles, thereby reduced the transmission gear that causes because of human element and synchro premature wear and damage, alleviated the driver fatigue degree, effectively improve the smooth gear shifting of many gears change-speed box.
Description of drawings
Fig. 1 is the utility model structural representation.
