Dry dual clutch Combined hydraulic release bearing assembly
Technical field
The present invention relates to a kind of dry dual clutch Combined hydraulic release bearing assembly, specifically make on pony car
Dry dual clutch Combined hydraulic release bearing assembly, belongs to automobile clutch separation technology field.
Background technology
Double clutch be one kind can passing power, and can cut off power transmission mechanism.Its effect mainly ensures
Automobile energy gentle start, mitigate the shock loading of change-speed gearing during gear shift and prevent power train from overloading.Dry dual clutch
There are two groups of clutches to alternate work, the release bearing and separating mechanism of two groups of independence need to be configured, with traditional single clutch
Complicated compared to its, appearance and size is big, weight weight.Therefore, used on pony car, relevant portion will be designed to more
It is compact, requirement could be met.Existing dry dual clutch realizes that the form of switching gear is to pass through on automobile gearbox
Two groups of disengaging yokes, which alternate, promotes two groups of release sleeves(Separation shaft bearing)Two groups of release bearings are driven in gear box I central siphon
Axial reciprocating slip is put, two groups of release bearings alternate two groups of diaphragm spring separation fingers of extruding and realize dry dual clutch
With reference to separation, gear shift is completed.Following defect be present in this switching gear form:During frequently switching gear, separation set
Cylinder reciprocatingly slides for a long time in gear box I central siphon set, easily wears between each other;Disengaging yoke and two shift fork branch on release sleeve
Bearing surface contacts for point, and impact noise is big, while shift fork bearing-surface contact position easily produces uneven abrasion, causes operation sense bad,
Gear shift is difficult.
