この考案は中空電機子軸にブレーキ用デイスク
を取り付けた駆動用電動機に関するものである。[Detailed Description of the Invention] This invention relates to a drive motor in which a brake disc is attached to a hollow armature shaft.
従来、ブレーキ用デイスクは車輪または車軸に
直接取り付けられているため、車両が高速走行す
る場合、車輪のレールに与える衝撃力が大きくな
るという欠点があつた。 Conventionally, brake discs have been attached directly to wheels or axles, which has had the disadvantage of increasing the impact force exerted on the wheel rails when the vehicle is traveling at high speeds.

A brake disc D is attached to the
A wheel W and a large gear P1 are fitted onto the axle A. Gear box C is attached to the axle via bearing B, and a large gear P1 is installed in the gear box.
and small gear P2 are included. The pinion P2 is directly connected to the spur gear G3 of the adjustable gear joint via the gear shaft Z. The other spur gear G1 of the adjustable gear joint is directly connected to the motor shaft X. The two spur gears G1 and G3 have a structure in which power can be flexibly transmitted by the internal gear G2.

る。 The driving electric motor M is directly connected to the bogie frame, but since the axle A is connected to the bogie frame via an axle spring, the deflection of the axle spring causes a relative displacement between the two, but this can be compensated for. He's escaping with a gear joint. The brake caliper T is flexibly attached as a countermeasure against this relative displacement. The power of the driving electric motor M is transmitted from the adjustable gear joint to the pinion P2,
It is transmitted to the wheels W via the large gear P1 and the axle A.

動用電動機を提供するにある。 This invention eliminates the above-mentioned drawbacks by attaching brake discs to both ends of the hollow armature shaft of the drive motor to reduce the mass of the wheel axle, thereby reducing the impact force exerted on the rail during high-speed running. A disk-equipped drive for brakes on electric railway vehicles that prevents slipping and skidding by transmitting the power from the hollow armature shaft to the wheels via the drive shaft and two sets of flexible plate joints with a torsion spring action.

２に伝わるようにしたものである。 In the embodiment of this invention shown in Fig. 2, the brake disc H is attached to both ends of the hollow armature shaft X1. Two sets of flexible plate joints F1, F2 and F3, F4 with small axial dimensions are used as flexible joints to reduce the mass of the wheel axle part and to transmit the power of the drive motor M to the pinion P2. This created a space for installing the brake disc H. The torque from the driving electric motor M and the brake disc H is the hollow armature shaft X1.
The signal is transmitted from the drive shaft to the flexible plate joints F1 and F2, and then through the drive shaft X2 passing through the hollow armature shaft X1 to the pinion P via the flexible plate joints F3 and F4.
This is to convey the message to the second person.

止にも役立つ。 As explained above, the drive electric motor with a brake disc according to this invention reduces the impact force exerted on the rail by reducing the mass of the wheel axle. Further, since the brake disc does not move relative to the truck frame, the brake caliper T can be directly connected to the truck frame, and the structure of the brake caliper T is simplified. Furthermore, by providing the drive shaft with a torsion spring action, fluctuations in torque from the drive electric motor M and the brake disc H are alleviated and transmitted to the axle wheels W, which also helps to prevent the wheels from slipping and slipping.
