Description

The double-motor assembly of the integrated dual planetary gear brake coupling of a kind of hybrid power passenger car

Technical field

The present invention relates to clutch field, refer more particularly to the double-motor assembly of the integrated dual planetary gear brake coupling of a kind of hybrid power passenger car.

Background technology

Tradition is exported by driving engine output Flywheel disc with the power of main cut-off clutch, utilize clutch-diaphragm spring and platen to produce precompressed compression to dry type friction lining and carry out transmitting torque, institute's transmitting torque reaches rear-axle drive wheel by driving system input clutch spindle through each transmission link.When normal engine drives Vehicle Driving Cycle, release thrust bearing the work that do not stress.When conventional manual speed change bus idling and gearshift, step on clutch slipper yoke promotion release thrust bearing compressive films plate spring and instigate a point Flywheel disc, friction lining and platen three to separate, interrupt the power between reasonable match system.Under two kinds of operating modes, may need release thrust bearing work: gearshift operating mode: this process generally continues about 2 seconds, each car needs release thrust bearing work approximately 5000 seconds every day, this working condition is for being interrupted operating mode, be after 2 seconds of release thrust bearing work, during to lower task, have a rest heat radiation time, this service condition has increased the service life of release thrust 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 live load of release thrust bearing, also makes extend its service life.Driving engine, 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.

Comprehensive analysis, the major cause that traditional bus release thrust bearing damages: the too high generation of operating temperature is overheated; Lack lubricating oil and wear and tear; Play motion is too little or number of load is too much; Whether separator levers is adjusted smoothly.Grease lubrication release thrust 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 thrust bearing operation 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 service life, requires frequent maintenance and replacement.
