製変速機用同期リングに関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a transmission made of a Cu-based sintered alloy, which has particularly excellent initial conformability of the contact sliding surface with a mating member and excellent wear resistance. This relates to a synchronization ring.

側につき、この外周側で相手部材であるテーパーコーン
と摩擦する、通称ピンタイプのものがある。Conventionally, a synchronizing ring for a transmission generally has an inner surface 1 that serves as a contact sliding surface with a rotating taper cone, and a tapered cone serving as a mating member on this contact sliding surface, as illustrated in a perspective view in FIG. are intermittently in surface contact under high surface pressure, and a key groove 3 into which a key fits is formed on the unilateral peripheral surface, and further,
Since the chamfers 2 provided at predetermined intervals along the outer edge have the function of engaging with the chamfers of the hub sleeve, which is also a mating member, they are required to have strength, wear resistance, and compatibility with the mating member. , therefore, high-strength brass with these characteristics is often used in its manufacture. In addition, there is also a so-called pin type synchronizing 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.

るようになり、使用寿命短命化の原因となっている。However, with the increase in the output of transmissions in recent years, the above-mentioned conventional high-strength brass synchronizing ring has become more difficult to connect with at least one of the mating members of the above-mentioned taper cone, key, and chamfer of the hub sleeve. Since the contact sliding surface is subjected to high surface pressure, initial conformability decreases, which leads to frequent abnormal wear such as bright surface wear and adhesive wear, leading to a shortened service life. ing.

It is a component that has excellent properties and prevents adhesion (seizure) due to plastic flow caused by local high-temperature heating, thereby preventing initial abnormal wear and improving initial conformability in oil pools. If the content is less than 10% and AD: less than 1.5%, it is not only impossible to ensure the above properties, but also it becomes difficult to form a work-hardened layer having the above properties. is Zn: 40% and Al: 8
If the content exceeds 10%, the toughness will decrease, so the content should be adjusted to Zn: 10-40%, Al1: 1.5-g.

Since it has the effect of further improving the effect, it is included as necessary, but if the content is less than 0.1%, the desired effect cannot be obtained in the above effect, while on the other hand, if the content exceeds 8%, the effect becomes even worse. Since it has no effect, its content was set at 0.1 to 8%.

た。(r) Porosity The pores in the alloy become oil pockets during practical use, which improves the initial conformability of the inner surface of the ring, suppresses the temperature rise of this, and prevents adhesive wear. It has the effect of improving wear resistance and normalizing wear by forming a thin oxide film on the pore surface, but if the proportion is less than 0.05% by volume, the desired effect cannot be obtained. On the other hand, if the proportion exceeds 5% by volume, the strength decreases and it becomes impossible to put it into practical use, so the proportion was set at 0.05 to 5%.
