Abstract
The utility model relates to the automobile parts, specifically to a split type pre-damping structure for a plastic split chuck. The split type pre-damping structure for the plastic split chuck comprises a core of the split chuck, a pre-damping spring and a pre-damping plate hub, and is characterized in that the plastic split chuck is sleeved on the core of the split chuck, wherein the plastic split chuck is provided with a circular plastic base plate, a circle of external flange is arranged from the periphery to one side of the plastic base plate, 4-6 stop bosses are uniformly distributed on the inner wall of the external flange, a spring installation position is formed between every two stop bosses, the pre-damping spring is arranged at the spring installation position, and a section of internal flange is designed inside each spring installation position; a stop block corresponding to each stop boss is designed on the plastic base plate, and a slot is formed between the stop block and the stop boss in a spaced manner; and a tongue piece corresponding to each slot is designed on the pre-damping plate hub, and a hook is designed on each tongue piece and stuck into a corresponding sticking slot. The split type pre-damping structure for the plastic split chuck disclosed by the utility model has the advantages of simplified structure, simpleness for assembling, increased production efficiency and low cost, and is mainly applied to a driven disc assembly of a dry friction type clutch of the automobile as the pre-damping structure.
Description
The (1) technical field: the utility model relates to auto parts and components, in particular for the split type preparatory vibration damping structure of a kind of plastics spring chuck in the dry type clutch clutch drived disk assy.
The (2) background technique: split type preparatory vibration damping structure is the important composition parts in the automobile clutch, and in the existing technology, split type preparatory vibration damping structure includes the dish core; On the dish core, be set with preparatory vibration damping driven disc and preparatory damping disk(-isc) and preparatory damping disk(-isc) hub, all have 4-6 spring window in the three dish structures, preparatory shock-absorbing spring is installed; And all adopt steel design, therefore there is complex structure in existing split type preparatory vibration damping structure, and component are many; Assembling difficulty is big, and manufacturing efficiency is low, shortcomings such as manufacture cost height; And full steel structure is being used for clutch driven disc assembly needs configuration damping fin in addition.On the other hand, the preparatory shock-absorbing spring that adopts in the existing split type preparatory vibration damping structure is generally linear springs, and the torsion angle of clutch is restricted, and is generally 5-7 °, influences ride comfort.
The (3) summary of the invention: it is more that the purpose of the utility model will overcome existing split type preparatory vibration damping structure component exactly; Assembling difficulty is big, and manufacturing efficiency is low, and manufacture cost is high; And torsion angle shortcoming such as is restricted, and provides a kind of plastics spring chuck split type preparatory vibration damping structure.
The concrete scheme of the utility model is: be designed with the dish core; Preparatory shock-absorbing spring and preparatory damping disk(-isc) hub is characterized in that: on the dish core, be set with a plastics spring chuck, this plastics spring chuck has the round plastic chassis; The middle part of plastic chassis has and coils the through hole that core cooperates installation; The periphery of plastic chassis is rib outside a side has played a circle, is evenly equipped with 4-6 backstop boss outside on the rib inwall, forms the spring installation position in twos between the backstop boss; Preparatory shock-absorbing spring is installed, and is designed with one section inner retaining side in each inboard, spring installation position; Corresponding each backstop boss is designed with block on plastic chassis, has spacing to form slot between block and the backstop boss; Corresponding each the slot design tongue piece of said preparatory damping disk(-isc) hub is designed with hook on each tongue piece, and the hook skewer is contained in the corresponding skewer groove.
On the plastic chassis of plastics spring chuck, lean on each inboard, spring installation position to be provided with a projection in the utility model, on each projection rubber sleeve is housed.With in idling when quickening switch operating, play buffer function.
Preparatory shock-absorbing spring is an arc spring described in the utility model.
Adopt a plastic chassis to replace original preparatory vibration damping driven disc and preparatory damping disk(-isc) and three parts of damping fin in the utility model; So designs simplification, part reduces, and manufacture cost reduces; Operating noise is littler; Adopt arc spring simultaneously, the torsion angle of clutch is increased more than 12 °, improved the travelling comfort of riding.
