Abstract

The utility model discloses a brake disc, which belongs to the field of railway locomotive vehicle brakes. In order to resolve the problems that cracks formed on existing brake discs can influence the driving safety and brings inconvenience to the replacement of brake discs, the two lateral sides of the wheel set spoke plate of the brake disc are provided with two butted semicircular split-type brake discs which are formed into an integrated brake disc with a locating chuck through a pin, and the brake disc tightly connected to the two lateral sides of the plate through fastening parts. The inner sides of the two semicircular split-type brake discs are provided with a plurality of radial key grooves, and corresponding key grooves of semicircular split-type brake discs arranged on two lateral sides of the wheel set spoke plate are connected with each other by pins which penetrate through wheel set spoke plate holes. The brake disc is simple in structure, convenient to mount and dismount, low in noise, reliable in connection, adopts the pin structure, avoids overloaded shearing force on screws, and effectively prolongs the service life of brake discs.

Description

A kind of brake disc
Technical field
The utility model relates to a kind of brake disc, belongs to the railway locomotive brake field.
Background technique
Along with improving constantly of domestic locomotive running speed, the power unit of locomotive brake all adopts disc brake.The effect of disc brake is when train is implemented braking, and the rubbing surface that makes brake lining vertically compress brake disc produces frictional force, produces braking moment thus, and the kinetic energy when locomotive is moved is converted into heat energy, locomotive is slowed down or parking thereby reach.
Development along with high speed, heavy loading locomotive, the heat energy that produces during locomotive brake is improving constantly, huge braking heat energy can make brake disc produce high temperature, distortion, and produce thermal stress thus, and brake disc inside is usually owing to reasons such as manufacturing process and materials, inevitably can there be some defectives, cause the brake disc crackle, thereby influence traffic safety.
At present, locomotive adopted is and all-in-one-piecely takes turns brake disk mountedly, and it makes brake disc after wearing away limit or brake disc generation fatigue crack, need make wheel to separating with axle during replacing, changes inconvenient.
Summary of the invention
After cracking at existing brake disc, influence traffic safety, and change the defective of inconvenience, the utility model aims to provide a kind of brake disc, and this brake disc can be installed reliably, and be convenient to change.
To achieve these goals, the technological scheme that the utility model adopted is: a kind of brake disc, be characterized in, the both sides of former all are equipped with the semicircle split type brake disc of two butt joints at wheel, the semicircle split type brake disc of two butt joints forms a complete brake disc by a pin and a location chuck, and this brake disc is connected in wheel to the former both sides by fastening piece is fastening; The inboard of described two semicircle split type brake discs is provided with a plurality of radially keyways, is connected with between the corresponding keyway of wheel to the semicircle split type brake disc of former both sides and passes the pin of wheel to the former hole.
The outer side surface of described semicircle split type brake disc is a rubbing surface, and inner side surface is provided with radiating fin.
For the ease of installing, described two semicircle split type brake discs are provided with two and are used to install the boss that two semicircle split type brake discs are used.
Described brake disc preferably by screw rod, elastic sleeve, lock nut is fastening is connected in wheel to the former both sides, good locking effect is played in the thermal distortion when elastic sleeve can adapt to brake disc work, guarantees the reliability that connects.
Further, the radially keyway on the semicircle split type brake disc of described two butt joints is six.
In order to dismantle with easy for installation, be equipped with one on the described pin and be used for and the rubber bullet pad of wheel location, former hole, wheel can be prevented shotpin play back and forth when high speed rotating, play the effect of location, noise reduction sound;
By said structure, semicircle split type brake disc forms for semicircle casting, the outer side surface of split type brake disc is a rubbing surface, inner side surface is provided with many radiating fin, two boss and six radially keyways that transmit braking moments that are used for two split type brake discs installation usefulness, bear under the huge braking energy at brake disc like this, the thermal expansion that the generation thermal stress causes can not be delivered on the pin, but along radially keyway direction transmission of brake disc; Pin mainly plays the effect of transmission braking moment, can avoid screw rod to bear suitable shearing force.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, removes and installs conveniently, noise is low, connect reliable, adopt pin structure, avoided adopting screw rod to bear excessive shearing force, increased the working life of brake disc effectively.
