Description

A kind of Pneumatic-control type dual planetary gear brake coupling
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 is exported by motor output Flywheel disc with the power of main cut-off clutch, utilize clutch diaphragm spring and platen to produce precompression to dry type friction plate and carry out transmitting torque, institute's transmitting torque reaches rear bridge driven wheel by transmission system input clutch spindle through each transmission link.When normal engine drives Vehicle Driving Cycle, release bearing the work that do not stress.When conventional 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 and platen three to separate, interrupt the power between reasonable match system.Under two kinds of operating modes, may need release bearing work: gearshift operating mode: this process generally continues about 2 seconds, each car needs release bearing work approximately 5000 seconds every day, this working condition is for being interrupted operating mode, be after 2 seconds of release bearing work, during to lower task, have a rest heat radiation time, this service condition has increased the working life of release bearing greatly; In addition, it is softer or just right that people's perception manipulation promotes disengaging yoke force rate, reduced to a great extent the axial dynamic load of release bearing, also makes extend its working life.Motor, in the time of high rotating speed, is stepped on cut-off clutch and is shifted gears very greatly on its impact in life-span, and the improper meeting of driver's operation greatly reduces its life-span.
Idling operation: in view of the applying working condition of bus, it has the time is greatly in idling mode, from above-mentioned two table statistics, its time probably accounts for 35% left and right of total run time.Generally, in the time of idling operation, select neutral to interrupt the power between motor and transmission system, 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 is adjusted smoothly.Grease lubrication release bearing considers that various factors is by the accounting of 1000 hours its life-spans, and traditional bus uses equivalent time to estimate for 7000 seconds every day, approximately uses 2 hours, so about the about 500-720 of bus release bearing service life days.In addition, owing to often needing half hitch to close step, dry type friction disc wear is serious.Therefore dry friction clutch is very short working life, requires frequent maintenance and replacement.
