Conventionally, in general, a synchronizing ring for a transmission has an inner surface 1 which is a contact surface with a rotating tapered cone, and a mating member Q, o, etc. on this contact surface, as illustrated in a perspective view in FIG.
- The cone is intermittently in surface contact under high surface pressure, while a keyway 3 into which a key fits is formed on the outer peripheral surface, and channels 7a 2 provided at predetermined intervals along the outer edge are also provided. Since it has the function of engaging with the chamfer of the hub sleeve, which is the mating member, it is required to have strength, wear resistance, and compatibility with the mating member. Brass is often used. In addition, there is also a type of synchronizing ring commonly known as a pink ring, which has a thread on the outer circumferential side and rubs against a tapered cone, which is a mating member, on the outer circumferential side.

However, as the output of transmissions has increased in recent years, the above-mentioned conventional high-strength brass synchronizing ring has been particularly affected by contact with at least one of the above-mentioned taper cone, key, and chamfer of the hub sleeve. As the surface is subjected to high surface pressure, the initial conformability decreases, which leads to frequent abnormal wear such as bright surface wear and adhesive wear, and shortens the service life. .

(a) Zn and M These components determine the base structure of the alloy, improve the wear resistance of the base, provide the strength and toughness necessary for the synchronous ring, and further improve fatigue strength. It has excellent yield strength and is essential for forming a work-hardened layer on the ring surface that prevents adhesion (seizure) due to plastic flow caused by local high-temperature heating, thereby preventing abnormal initial wear and improving initial conformability. However, if its content is less than 20% or less than A22291, it will not only be impossible to ensure the above properties, but also it will be difficult to form a work-hardened layer with the above-mentioned inertia. The content is Zn

(b) 8i and Mn These components combine with each other to form intermetallic compounds that are finely dispersed in the matrix to improve the strength and toughness of the ring, and also improve wear resistance. In addition, the conformability and seizure resistance of the work-hardened layer have the effect of improving properties, but the content of Si: less than 0.2% and Mn:
If the content is less than 0.1%, the desired effect cannot be obtained; on the other hand, if the content is less than 0.1%, the desired effect cannot be obtained.
If it exceeds 0.2% to 2%, Mn: 0.1%, Si: 0.2% to 2%, Mn: 0.1%.

(d) Ti, Zr, and Cr These components include the Mn-Si intermetallic compound dispersed in the base material, which is made into fine spherules, and which itself forms a composite compound with Mn and Si, resulting in one strength, Since it has the effect of improving toughness and wear resistance, it is included as necessary, but if the content is less than 0.05%, the desired effect of improving the above effects cannot be obtained; Even if it exceeds 1.5%, no further improvement effect appears, so the content was set at 0.05 to 1.5% in consideration of economic efficiency.

(e) Work-hardened layer The work-hardened layer is processed by shot blasting or sandblasting as described above, and when it is provided only on the friction surface with the taper cone of the ring, for example, by using a steel die,
Pressure can be formed by cold pressing, etc., and the work-hardened layer formed in this way, combined with its component composition, has excellent fatigue strength and yield strength. It exhibits excellent plastic flow resistance against localized high-temperature heating, and as a result, it suppresses seizure, etc., thereby preventing abnormal initial wear and exhibiting excellent initial conformability, but the average layer thickness If the average layer thickness is less than 5 μm, the desired effect cannot be obtained, and even if the average layer thickness exceeds 300 μm, excellent effects cannot be ensured. Therefore, the average layer thickness was determined to be 5 to 300 μm.
