Description
Technical field
The utility model is related to half grade of lock ring type synchronized assembly of odd-side before a kind of new heavy multi-speed transmission, belongs to
Heavy-duty automotive speed changer field.
Background technology
Gradually increase for current domestic heavy hauler market engine horsepower and output torque, it is desirable to heavy-duty transmission
Transmission torque ability gradually increase, gear number increases.It is in the world at present lifting heavy-duty transmission gear number, while controlling speed change
The length and weight of device, widely used preceding odd-side structure.Compressed-air shifting being used preceding odd-side gear shift, compressed-air shifting needs synchronizer more
Realize that high and low shift is changed.At present, domestic relatively fewer using the heavy-duty transmission of preceding odd-side structure, restraining factors are mainly preceding pair
The design of case synchronizer structure is more complicated, and preceding auxiliary box synchronizer structure needs to be innovated.
The content of the invention
The purpose of this utility model is to provide half grade of lock ring type synchronization of odd-side before a kind of new heavy multi-speed transmission
Device assembly, preceding half grade of lock ring type synchronized assembly structure of odd-side is compact, design is succinct, adapt to odd-side before heavy multi-speed transmission
Gear shift.
What the technical solution of the utility model was realized in：Half grade of lock ring type of odd-side before new heavy multi-speed transmission
Synchronizer assembly, it is synchronous by synchronizer gear seat, spring, pushing block, high-grade synchronous ring, low-grade synchronous ring, high-grade synchronous cone and low grade
Cone composition；It is characterized in that：Synchronizer gear seat correspondence hole site is provided with spring, and pushing block lead is arranged in spring bores,
Steel ball coordinates with V-groove in the middle part of synchronizer gear sleeve at the top of pushing block；High-grade synchronization ring inner conical surface bonding carbon fiber friction material, with height
Shelves synchronous cone male cone (strobilus masculinus) coordinates；Low-grade synchronization ring inner conical surface bonding carbon fiber friction material, coordinates with low-grade synchronous cone male cone (strobilus masculinus).
Described synchronizer gear seat is uniformly distributed circumferentially three grooves, and bottom land is provided with spring base hole.
Described synchronizer pushing block uses band lead pushing block.
Described synchronizer gear seat end face has is machined with oilhole on oil-way, synchronous cone, it is ensured that synchronous ring and same
The flowing of lubricating oil at step cone mating surface.
Good effect of the present utility model is that synchronous ring inner conical surface is bonded with carbon fiber friction material, it is ensured that have larger rub
Area is wiped, makes the capacity of synchronizer enough；Using forging, spline tooth number is few, saves material, the synchronous ring gearshift procedure of reduction
In deformation.
