▷ Review t/m capacity
▷ Design double cone syn.ring
▷ Suggest new design of double syn.ring to enlarge capacity
▷ Building prototype samples
▷ Test double syn. ring samples

Test Method & Result
Now under bench test for modified syn. ring
(Bench test, vehicle test)

Motivation
Need to improve shift feeling in step 2nd.
(Not excellent shift feeling in all steps)
2
Activity
▷ Design review : current type t/syn.ring makes the syn. ring assembly seem unstable.
▷ Suggest 4types of design.
(D/SYN, D/SYN+PAPER, CHANGING OF T/SYN TAPER ANGLE, SINGLE TYPE+PAPER)
▷ Building prototype samples.
▷ Test samples.

Test Method & Result
Finished the bench of d/syn. → syncronizing time is shorter than t/syn.
Now under vehicle test of d/syn.
Now under porducing other samples.

Applicatons
Plan to apply the best of above sample in vehicles after all test.
No.

Activity
▷ Design review : not enough capacity in performance.
▷ Suggest modifying a design to double syn. ring to enlarge capacity.
▷ Building prototype samples.
▷ Test samples.

Test Method & Result
Now under producing vehicle test of d/syn.
→ Syn. ring capacity is increased than single type

Motivation
Because of inferior synchronizing and engagement.

Activity
▷ Estimate that syn. ring → capacity deficiency.
▷ Suggest modify a design to paper syn. rign to enlarge capacity.
▷ Building prototype samples
▷ Test samples
3
Test Method & Result
Finished bench & vehicle test of paper syn. ring
→ Syn. ring capacity is increased than single type

Applicatons
Under mass production with paper syn. ring → apply to vehicles
