Serious waste, lead to cost increase.Applicable part vehicle.There is no solve asking for adaptation different automobile types in fact for this scheme
Topic.
2, Serial scheme：To 10 seriation of electronic parking actuator, each series all designs different shell and at least
Variation is from motor shaft to the transmission mechanism of planetary gear main shaft.More parts are developed, seriation is completed, it thus can be preferable
Ground is suitable for different vehicles, the disadvantage is that causing the amount of parts of exploitation more, the normalisation coefft of reduction causes bigger
Stock control workload, more mistake proofings work, eventually lead to cost increase.
The shortcomings that current art is which kind of scheme no matter all necessarily to lead to the rising of cost using.How quality is being ensured
Under the conditions of, less parts are developed, normalisation coefft, better mistake proofing management is improved, becomes the electronic parking skill of this field
Important topic in art research and development.
