Embodiment Construction

[0033] The core of the present invention is to provide a frame-suspended driving device with a hollow shaft disc brake to solve the problem of large intersprung mass of the driving device with an independent brake shaft in the prior art. On this basis, the present invention also provides a two-axle bogie using the above-mentioned driving device.

[0034] Without loss of generality, the following describes in detail the specific implementation of the suspension drive device for the hollow shaft disc brake with reference to the accompanying drawings.

[0035] See Figure 5 and Figure 6 ,in, Figure 5 show image 3 Front view of the drive unit, Figure 6 showed Figure 5 top view.

[0036] Such as Figure 6 As shown, this solution provides a hollow-shaft disc brake drive device for pulling and braking the wheels 27 of a locomotive. The drive device includes: a traction motor 2605, a transmission gearbox 2604, a bracket 2609 and braking unit 2612, also includes inner holl...

Abstract

The invention discloses a frame suspension type drive device with a disk-shaped braked hollow shaft for a wheel set for towing and braking a locomotive. The frame suspension type drive device comprises a traction motor, a transfer gearbox, a support and a braking unit, and also comprises an inner hollow shaft and an outer hollow shaft which are sequentially sleeved on the axle of the wheel set, wherein one end of the inner hollow shaft is in transmission connection with a wheel of the wheel set, and the other end of the inner hollow shaft is in transmission connection with the outer hollow shaft; one end of the outer hollow shaft is in transmission connection with the transfer gearbox, the other end of the outer hollow shaft is in transmission connection with the support, and a braking disk of the braking unit is fixedly arranged on the outer hollow shaft; and one ends of the traction motor and the braking unit are fixedly connected with the support, and the other ends of the traction motor and the braking unit are connected with the frame of a bogie in a suspending manner. Compared with the prior art, the drive device has the advantages of reducing mass between a primary suspension and a secondary suspension of the locomotive, optimizing dynamic property of the locomotive, and ensuring the stability of the locomotive in an operation process. The invention also discloses a two-shaft bogie adopting the drive device.

Description

technical field [0001] The invention relates to the technical field of rail locomotives, in particular to a two-axle bogie and a frame-suspension driving device for a hollow shaft disc brake. Background technique [0002] At present, the domestic two-axle bogie technology for passenger locomotives or power vehicles is still at the level of the 1990s, the driving device adopts rigid suspension technology, and the foundation brake adopts tread brake or wheel brake , these technologies limit the development of B0-B0 passenger locomotives. [0003] An elastic suspension drive with disc brakes, including a wheel set with a brake disc, an axle and a traction motor of the wheel set rotatably connected by bearings, and a geared hollow shaft transmission that transmits the torque of the traction motor to the axle mechanism. The traction motor and the gear hollow shaft transmission mechanism are fixedly connected by bolts to form an integral driving device, and the system is elastic...
