Description
Technical field
The present invention relates to clutch field, refer more particularly to a kind of Pneumatic-control type dual planetary gear brake coupling.
Background technique
Tradition exports Flywheel disc with the power of main cut-off clutch by motor and exports, utilize clutch diaphragm spring and platen to produce precompression to dry type friction plate and carry out transmitting torque, institute's transmitting torque inputs clutch spindle by transmission system and reaches rear bridge driven wheel through each transmission link.When normal engine drives vehicle to travel, release bearing the work that do not stress.When traditional manual speed change bus idling and gearshift, step on clutch shifter promotion release bearing compressive films flat spring and instigate a point Flywheel disc, friction plate to be separated with platen three, interrupt the power between reasonable match system.Namely release bearing work may be needed under two kinds of operating modes: gearshift operating mode: this process generally continues about 2 seconds, each car needs release bearing work about 5000 seconds every day, this working condition is for being interrupted operating mode, namely after release bearing work 2 second, to having a rest heat radiation time during lower task, this service condition considerably increases the working life of release bearing; In addition, it is softer or just right that people's perception manipulation promotes disengaging yoke force rate, reduces the axial dynamic load of release bearing to a great extent, also make extend its working life.When motor is in high rotating speed, step on cut-off clutch and carry out shifting gears to its aging effects very greatly, the improper meeting of driver's operation makes its life-span greatly reduce.
Idling operation: in view of the applying working condition of bus, it has greatly, and the time is in idling mode, and from above-mentioned two table statistics, its time probably accounts for about 35% of total run time.Generally, when idling operation, selection neutral interrupts the power between motor and transmission system, and now, release bearing is in off working state.
Comprehensive analysis, the main cause that traditional bus release bearing damages: the too high generation of operating temperature is overheated; Lack lubricant oil and wear and tear; Free travel is too little or number of load is too much; Whether separator levers adjusts smooth.Grease lubrication release bearing considers that various factors was adjusted by 1000 hours its life-spans, and traditional bus uses equivalent time to estimate for 7000 seconds every day, about uses 2 hours, so bus release bearing service life is about about 500-720 days.In addition, owing to often needing quasi integration to start to walk, dry type friction disc wear is serious.Therefore dry friction clutch is very short for working life, requires frequent maintenance and replacement.
