置することが困難な場合があった。(Prior art) Floating type brake discs were first developed in 1980.
As seen in 3333, the braking part and the hub are constructed separately and connected to allow slight movement between the two parts to prevent distortion of the braking surface due to frictional heat during braking. As a means for connecting the two parts, it is common to use a bottle inserted into opposing recesses provided in both parts. The bolt that connects the hub to the hub has a head on one end and a disc spring and washer are caulked to the other end.In order to connect the hub to the axle, a nut is screwed onto the bolt that passes through the hub. Ta. Since the bottle head or countersunk and nut are located on the side of the hub, they must be placed apart from each other so that they do not interfere with each other, but for small brakes, they should be placed far apart. was sometimes difficult.

する。(Ninth means for solving the problem) Invention #'i (The connecting part between the braking part and the hub is formed in a small size to avoid interference between the connecting part and the nut for connecting the axle, and the brake disc is made small and lightweight. It was designed so that it can be configured as follows.
This means that in a brake disc in which a hub is connected to the inner periphery of a ring-shaped brake part so as to be able to move minutely, there is a receiving part in the axle direction that spans both parts, and a steel plate accommodated in the receiving part. It is characterized by having a plurality of connecting parts each consisting of a ball and a caulking part in which both the front and back ends of the receiving part are caulked inward.

、車軸連結用のナツトと干渉することがない。(Function) With the above configuration, the braking part and the knob are connected to each other so as to be able to move minutely by the steel balls on the day of receipt, and the braking torque is transmitted via the steel balls. Since the steel balls are held by the caulking portions at both ends of the receiver to form the connecting portion, the connecting portion is small and does not interfere with the axle connecting nut.

When the steel ball is formed, the steel ball is enclosed in the receiving part (2) and connects the braking part (2i) to the braking part (3) to transmit braking torque. There is a slight gap between each receiving hole half part (12a), (12b) and the steel ball (end), and the braking part (2) and hub (3) have slight relative movement in the radial and axial directions.

ある。(Effects of the Invention) As described above, the connecting portion of the present invention can be made compact, so even in a small brake disc that requires the nut and the connecting portion to be placed close to each other to be attached to the axle, the nut and the connecting portion can be made small. parts can be easily arranged without mutual interference. Further, the processing such as drilling and caulking the receiving part in the penetrating state is extremely simple, and only inexpensive steel balls are used as parts, so the brake disc can be manufactured at low cost and efficiently. Furthermore, since the connecting part is simple, it is easy to provide a large number of these parts to reduce the load per piece, which makes it possible to reduce the size of the connecting part. A thin plate material can be used for the brake, which is useful for making the brake smaller and lighter.
