Abstract
The invention relates to an automobile part, in particular to a plastic spring chuck split-type pre-damping structure. The plastic spring chuck split-type pre-damping structure is provided with a disc core, pre-damping springs and a pre-damping disc hub and is characterized in that a plastic spring chuck is sleeved on the disc core; the plastic spring chuck is provided with a round plastic chassis; a circle of outer flange is arranged on the periphery of the plastic chassis towards one side; 4 to 6 stop bosses are uniformly distributed on the inner wall of the outer flange; a spring installation position is formed between each two stop bosses; the pre-damping springs are arranged at the spring installation positions; a section of inner flange is designed inside each spring installation position; check blocks are design at the positions of the plastic chassis, which correspond to each stop boss; distances are reserved between the check blocks and the stop bosses to form slots; corresponding to each slot, the pre-damping disc hub is provided with a tongue; each tongue is provided with a claw; and the claws are inserted in the corresponding slots. The plastic spring chuck split-type pre-damping structure has simplified structure, is simple to assemble, has improved production efficiency and low cost and is mainly used as the pre-damping structure in an automobile dry friction clutch driven disc assembly.
Description
(i) technical field: the present invention relates to auto parts and components, in particular for the split type pre-vibration damping structure of a kind of plastics spring chuck in dry type clutch clutch drived disk assy.
(ii) background technique: split type pre-vibration damping structure is the important composition parts in automobile clutch, in prior art, split type pre-vibration damping structure includes dish core, dish core is set with pre-vibration damping driven disc and pre-damping disk(-isc) and pre-damping disk(-isc) hub, 4-6 spring window is all had in three dish structures, pre-shock-absorbing spring is installed, and all adopt steel design, therefore there is complex structure in existing split type pre-vibration damping structure, component are many, assembling difficulty is large, manufacturing efficiency is low, the shortcomings such as manufacture cost is high, and full steel structure, need to configure damping fin in addition in for clutch driven disc assembly.On the other hand, the pre-shock-absorbing spring adopted in existing split type pre-vibration damping structure is generally linear springs, the torsion angle of clutch is restricted, is generally 5-7 °, affects ride comfort.
(iii) summary of the invention: it is more that object of the present invention will overcome existing split type pre-vibration damping structure component exactly, assembling difficulty is large, and manufacturing efficiency is low, and manufacture cost is high, and torsion angle such as to be restricted at the shortcoming, provides a kind of plastics spring chuck split type pre-vibration damping structure.
Concrete scheme of the present invention is: be designed with dish core, pre-shock-absorbing spring and pre-damping disk(-isc) hub, it is characterized in that: on dish core, be set with a plastics spring chuck, this plastics spring chuck has round plastic chassis, the middle part of plastic chassis has and coils core and coordinate the through hole installed, the periphery of plastic chassis has played rib outside a circle to side, rib inwall is evenly equipped with 4-6 backstop boss outside, spring fitting position is formed between two between backstop boss, pre-shock-absorbing spring is installed, and is designed with one section of inner retaining side inside each spring fitting position; On plastic chassis, corresponding each backstop boss is designed with block, has spacing to form slot between block and backstop boss; The corresponding each socket designs tongue piece of described pre-damping disk(-isc) hub, each tongue piece is designed with hook, and hook skewer is contained in corresponding skewer groove.
Rubber sleeve is equipped with in the present invention on the plastic chassis of plastics spring chuck, by being provided with a projection inside each spring fitting position, each projection.With when idling is with acceleration switch operating, play buffer function.
Described in the present invention, pre-shock-absorbing spring is arc spring.
Plastic chassis is adopted to instead of original pre-vibration damping driven disc and pre-damping disk(-isc) and damping fin three parts in the present invention, therefore designs simplification, part reduces, manufacture cost reduces, operating noise is less, have employed arc spring simultaneously, the torsion angle of clutch can be made to increase more than 12 °, improve travelling comfort by bus.
(iv) accompanying drawing illustrates:
Fig. 1 is general structure plan view of the present invention;
Fig. 2 is the left sectional view of general structure of the present invention;
Fig. 3 is the plan view of plastics spring chuck in the present invention;
Fig. 4 is the A-A view profile in Fig. 3;
