Have.To adapt to various circulation circles, blade design is at approximate fusiform plain vane, the lesser straightedge vane of degreeof tortuosity
Deng complete fusiform blade is less.In the case where same blade imports and exports angle, since fluid torque-converter recycles round and space three-dimensional
The difference of blade construction, fluid torque-converter performance level differ greatly, and especially transmission efficiency influences the most obvious.All
Best with the performance of circular loop circle, the fluid torque-converter of approximate aerofoil blade structure in structure, entire operating condition transition is steady,
Higher efficiency range is wide, and the declared working condition matching of high-efficiency point speed ratio and engine is best, but fabricates difficulty and improve.Remaining structure because
Using plain vane, overall performance is all declined, though individual fluid torque-converter peak efficiencies are promoted, after high-efficiency point
It moves, higher efficiency range narrows, and has the complete machine of performance requirement unsuitable entire working condition, to the type with coupling operating condition
Compare applicable.The utility model is the emulation manufacture for combining the actual use operating condition of fluid torque-converter, and considering blade mold
Processing and blade casting divide difficulty when mould, and the circulation circle structure and space three-dimensional flow linear leaf that the one kind researched and developed is approximate circle
Chip architecture, and through multiple optimization design and verification experimental verification, fluid torque-converter entirety transmission efficiency is improved significantly, especially integrally
Transmission performance is steady from damped condition to high-speed working condition variation tendency, and higher efficiency range is wide, the specified work of high-efficiency point speed ratio and complete machine
Condition matching is intact.This fluid torque-converter performance should belong to leading level at home.
