Summary of the invention
The purpose of this utility model is the independent brake shaft device providing a kind of motor-hollow axle formula support scheme, to reach the problem solving independent brake bearing load braking support reaction, solve the problem that brake disc is installed, changed difficulty, and improve the object of vertical dynamics performance.
A kind of motor-hollow axle formula independent brake shaft device provided by the present invention, by band brake gear wheel shaft drive gearbox, braking turn round axle, cog-wheel coupling, cog-wheel coupling, brake empty axle, drg, brake support frame, independent brake bracing strut and braking accessory form, above-mentioned each assembly constitutes brake unit functional module, can move into as its brake system according to bogie truck particular case entirety; It is characterized in that: described braking is turned round between axle with brake tooth wheel shaft and is connected by cog-wheel coupling, described braking is turned round axle and is connected by cog-wheel coupling with brake empty axle, and described brake support frame is connected with independent brake bracing strut with the drive gearbox of band brake gear wheel shaft.
Described brake empty axle one end is connected by bearing with the support be fixed on brake support frame, and the described brake empty axle other end is connected by bearing with brake axle support.
The drive gearbox of described band brake gear wheel shaft is necessary for casing bearing-type gear case, and brake tooth wheel shaft is arranged on the non-motor side of drive gearbox big gear wheel, and is parallel to wheel to shaft centre line.Brake tooth wheel shaft is by bearing two dot point in the drive gearbox of band brake gear wheel shaft, and external part is turned round axle by cog-wheel coupling and braking and is connected.
The utility model the non-motor side of drive gearbox big gear wheel be provided with one be parallel to wheel axle is turned round to the braking of shaft centre line, the brake empty axle that brake disc is housed is turned round axle by gear coupling with this braking and is connected, realize reel braking.Braking is turned round axle and is connected with the brake tooth wheel shaft in drive gearbox by cog-wheel coupling, and brake empty axle one end is being cemented on the support on brake support frame by bearings.Its other end by bearings with on independent brake bracing strut.Under damped condition, hollow outer shaft bears brake torque and braking support reaction, and braking is turned round axle and only born the brake torque transmitted by hollow outer shaft.
Working process of the present utility model and principle are:
Under braking mode, the brake torque that drg produces acts on brake empty axle, brake empty axle passes to braking through cog-wheel coupling and turns round axle, the brake tooth wheel shaft that beam warp cog-wheel coupling passes to drive gearbox is turned round in braking, pass to wheel by spragging gear beam warp big gear wheel right, thus realize bogie truck braking.
Compared with prior art, the utility model has the advantage of:
1, motor-hollow axle formula independent brake shaft device of the present utility model, architecturally, belong to one is sprung weight to integral hanging, reduces locomotive to the dynamic deformation from motion of wheel track;
2, motor-hollow axle formula independent brake shaft device of the present utility model, brake axle is an independently unit, and easy accessibility, is convenient to the repair and maintenance of brake equipment, reduces application cost;
3, motor-hollow axle formula independent brake shaft device of the present utility model, an axle transmitting torque is turned round in braking, and braking support reaction is supported by brake empty axle bearings at both ends, solves braking and turns round the problem that axle can not bear larger braking support reaction.
In sum, the utility model solves the problem of independent brake bearing load braking support reaction, owing to being provided with independent brake axle, which solves the problem that brake disc is installed, changed difficulty, also achieving in typotron reduction one is as far as possible unsprung weight, improves the target of vertical dynamics performance.Therefore, the utility model has and increases the service life, installs the good effect changing easily, improve vertical dynamics performance.

Detailed description of the invention
Below in conjunction with accompanying drawing and concrete example, the utility model is further described.
As shown in drawings, motor-hollow axle formula independent brake shaft device of the present utility model, it mainly comprise band brake gear wheel shaft 4 drive gearbox 6, braking turn round axle 5, cog-wheel coupling 3, cog-wheel coupling 9, brake empty axle 2, drg 11, brake support frame 7, independent brake bracing strut 12 and braking accessory.
Braking is turned round axle 5 and is connected by cog-wheel coupling 3 with brake tooth wheel shaft 4, and braking is turned round axle 5 and is connected by cog-wheel coupling 9 with brake empty axle 2, and brake support frame 7 is connected with independent brake bracing strut 12 with the drive gearbox 6 of band brake gear wheel shaft.These parts constitute a relatively independent brake equipment jointly.
As shown in Figure 1, braking is turned round axle 5 and is connected by cog-wheel coupling 3 with brake tooth wheel shaft 4, and braking is turned round axle 5 and is connected by cog-wheel coupling 9 with brake empty axle 2.Described brake empty axle 2 one end is connected by bearing 1 with the support be fixed on brake support frame 7, and described brake empty axle 2 other end is connected by bearing 10 with brake axle support 12.Therefore, brake empty axle 2 can be disintegrated by the mode of bearing, and braking is turned round axle 5 and can be disintegrated by the mode of cog-wheel coupling, thus offers convenience to the repair and maintenance of brake disc 8.
As shown in Figure 1, the drive gearbox 6 of band brake gear wheel shaft is casing bearing-type gear case, and brake tooth wheel shaft 4 is arranged on the non-motor side of drive gearbox big gear wheel, and is parallel to wheel to shaft centre line.Brake tooth wheel shaft 4 passes through bearing two dot point in the drive gearbox 6 of band brake gear wheel shaft.Brake tooth wheel shaft 4 external part is turned round axle 5 by cog-wheel coupling 3 and braking and is connected.
