Existing braking disc locks in the side of locomotive wheel through the axis hole 41 of this inner disc 40, and the clamping machine of the locomotive then corresponding both sides being located at this outer disk 50, in brake process, this clamping machine inwardly this outer disk 50 clamping to produce frictional force, and then make the wheel in rotation via the inner disc 40 of riveting with this outer disk 50 phase to reduce rotating speed until stop, but, the braking disc of prior art only utilizes the plurality of fastener 52, to fix this inner disc 40 and outer disk 50, due to high heat and external force can be produced this outer disk 50 to contact clamping during with this clamping machine, this fastener 52 deformed damaged will be caused under permanent use, the situation this outer disk 50 and inner disc 40 being produced get loose and affect the safety of driving.

Model utility content

Because the shortcoming of braking disc of aforesaid prior art, the utility model improves existing braking disc, the generation of the situation that gets loose with the structural soundness and avoiding promoting braking disc.

The utility model solves the improved type braking disc that prior art problem proposes, and it comprises:

One inner disc, it has an axis hole and multiple tank, and this axis hole is applied in the centre of this inner disc, and the plurality of tank is recessed to be formed on the outer edge surface of this inner disc; And

One outer disk, it is ring slice of inner hollow and connects this inner disc, this outer disk has multiple inner edges protuberance and multiple fastener, the inner edge surface that the plurality of inner edge protuberance is formed in this outer disk is connected in the plurality of tank respectively, the both sides internal face of each tank is two-way coated and against this inner edge protuberance respectively, and the plurality of fastener is riveted on the joint of the tank of this inner disc and the inner edge protuberance of this outer disk respectively.

Further, this inner disc is a regular pentagon structure and is provided with five tanks, this five tank is respectively on the recessed outer edge surface forming in this inner disc and the span of each two adjacent tanks is equal, and this outer disk is provided with five inner edge protuberances, and this five inner edges protuberance is connected in the corresponding tank of this inner disc respectively.

Further, the internal face of each tank is arranged with two relative interior breach, the outer wall of each inner edge protuberance is arranged with two outer breach, two outer breach of each inner edge protuberance align respectively corresponding tank two in breach to form manhole.

Further, this fastener is rivet and is riveted in each manhole.

Multiple inner edges of the present utility model protuberance is spacing by the clamping of multiple tank, and utilize multiple fastener as the assembly of this outer disk of auxiliary positioning and inner disc, when practical application, the internal face of the tank of this inner disc can bear most external force produced when braking, deformed damaged is caused because bearing too much external force to avoid this fastener, so can significantly promote structural soundness of the present utility model, and the generation of situation of avoiding getting loose.

Embodiment

Below coordinating accompanying drawing and preferred embodiment of the present utility model, setting forth the technological means that the utility model is taked for reaching predetermined model utility object further.

Refer to shown in Fig. 1, improved type braking disc of the present utility model comprises inner disc 10 and an outer disk 20.

Refer to shown in Fig. 1 to Fig. 3, aforesaid inner disc 10 is a regular pentagon structure and is provided with axis hole 11, five tank 12 and ten through holes 13, this axis hole 11 hole formed therethrough is in the centre of this inner disc 10, this five tank 12 is respectively on the recessed outer edge surface forming in this inner disc 10 and the span of each two adjacent tanks 12 is equal, the internal face of each tank 12 is arranged with two relative interior breach 121, this ten through hole 13 is formed in this inner disc 10 around in the both sides outer wall of this axis hole 11, by the setting of this through hole 13 to alleviate the weight of this inner disc 10.

Aforesaid outer disk 20 is the ring slice of inner hollow and connects this inner disc 10, this outer disk 20 is provided with five inner edge protuberances 21, multiple radiation hole 22 and multiple fastener 23, this five inner edges protuberance 21 extension forms on the inner edge surface of this outer disk 20, the outer wall of each inner edge protuberance 21 is arranged with two outer breach 211, this five inner edges protuberance 21 is connected in the corresponding tank of this inner disc 10 12 respectively, the both sides internal face of each tank 12 is two-way coated and against this inner edge protuberance 21 respectively, two outer breach 211 of each inner edge protuberance 21 align respectively corresponding tank 12 two in breach 121 to form manhole, in the both sides outer wall that the plurality of radiation hole 22 is formed in this outer disk 20 and around this inner disc 10, in the manhole that the outer breach 211 of interior breach 121 and this inner edge protuberance 21 that the plurality of fastener 23 is installed in this tank 12 is respectively formed, in a preferred embodiment, this fastener 23 is rivet.
