Gear assembly for automobile gear transmission
First Claim
1. In a gear assembly having a pair of driving and driven gears permanently in meshing engagement with each other to provide a torque transmission therebetween, an additional gear axially slidable and rotatable on a hub projection of either one of said gears and being permanently in meshing engagement with the other gear to rotate at a gear ratio different from that of said driving and driven gears, a synchronizer mechanism assembled adjacent to said additional gear and having a spline piece fixed to the hub projection of said gear, and resilient means for resiliently pressing said additional gear against one end face of said gear adjacent thereto,the improvement wherein said resilient means is a compression spring arranged in surrounding relationship with the hub projection of said gear and being engaged at its one end with said additional gear and at its other end with the spline piece of said synchronizer mechanism.
