Description
2~l3S5~
Background of the Ill~ention ~d Plior Art The invention relates to a brake installation for railborne vehicles comprising at least one wheel axle driven by a coupled motor-transmission unit in which the unit is connected for driving to the wheel axle in a manner avoiding an intermediate gear, preferably by way of a hollow shaft concentrically enveloping this wheel axis and the wheel axle or the hollow shaft is connected for transmitting a driving force to a disc brake provided on that side of the wheel axle which is opposite to the unit.
, A const~uction is known for suburban coaches, haYing relatively low power and 10 low mass, in which a pinion of the drive motor directly drives a gear on the wheel set shaft, whereby an intermediate gear which increases losses of engine power can be avoided. On that side of the wheel set which is opposite to the motor, a special power take-off is provided on the gear to which a floating brake disc is fitted. However, this method sf mounting of a brake disc is not 15 suitable for relatively high motor powers respectively relatively high vehicle weights because of the required increased brake capacity and the stressing of the mountings for the brake installations connected therewith.
:
1 7or ~at reason, in the case of ~ailborne vehicles ha~ving higbe~ motor capacities and relatively high weight, the brake discs h~ve been built onto the wheel axis 2 0 respectively the hollow shaft surrounding the latter, involving the drawback, however, that the distance between t~e motor and the wheel a~le must be increased in order to provide room for the brake discs, so that it is then necessary to provide an intermediate gear in the transmission which results in additional power loss. Moreover, in that case only relatively limited space is 2 5 a~lailable for Iqt~ng the brake discs.
2~06~48 General Description of the In~ention Accordingly, it was the object of the present invention to provide a brake installation suitable also for high motor power and high vehicle weights, havingadequate brake capasity and wherein simultaneously the loss of motor power 5 can be reduced to a miniml~m and wherein the available space in the region of the wheel axis is well utilised.
This object is attained in accordance wi~ the invention in that the brake disc is fitted on a brake shaf~ arranged parallel to the wheel set a~le and to the motorshaft and mounled on two sides to the motor-transmission unit. Due to the 0 mounting of the brake shaft on two sides, a mechanically substantially more stable construction is attained which can accommodate a substantially hi~her brake capacity. At the same time, however, it remains possible to arrange the motor as close as possible to the wheel a~le, thereby avoiding the intermediate gear in the transmission which would increase the power loss. This is of 5 particular importance with motors havLng more than 1 MW cruising capacity, where even power losses or gains in a percentage range are of decisive importance.
The raising of the brake capacity rendered possible for the construction according to the invention also results in a reduction of the thermal and 2 o mechanical stressing of the wheels, because the employment of block brakes ~ -acting onto the wheels can be avoided.
According to a fur~er ~eature of ~e invention, it is a~vantageous for a bealing of the brake shaft, preferably that bearing which is opposite to the dnving connection to the wheel axle or the hollow shaft, to be releasable. I~nis renders 25 it easy to expose one end of the shaft in order to perform a brake disc replacement or to be able, if necessary, to remove the entire shaft in a simple ma~er.

The 5 railborne vehicle equipped in accordance with the invention may be provided with whatever brake capacity is suitable for the purpose, the upper limits thereof depending solely on the a~ailable space on the brake shaft.
E7Or that purpose it is possible on the one hand to interchange the çntire brakeshaft and replace it by another brake shaft having a different number of brake 10 discs firmly mounted thereon. However, advantageously according to a further feature of the invention the brake discs are fitted to the brake shaft in a releasable manner so that in a less expensiYe manner it is possible to increase or decrease the brake capacity merely by additionally ~ltting or removing the desired number of brake discs.
15 According to a further feature of the invention the brake callipers as well are fitted to the motor-transmission unit. In ~his manner relative movements between the brake discs and the brake callipers are avoided so that a uniform application of the brake power and a design of simple construction is made available whilst avoiding floa~ngly molmted components.

2106~8 DescIiption of Specif~c Embodiment The drive motor is denoted as 1 and typically supplies in modern, high capacity locomotives a cruising capacity of about 1,6 MW. A transmission 2 flange-connected ~ereto drives on the one hand a hollow shaft 3 which is connected in 5 driving relationship to the wheel set a~is (not illustrated3. At the same time, however, also on ~hat side which is opposite to the motor 1 of the hollow shaft 3 a power take-off is provided to which a brake shaft 4 is fitted in driving relationship.
l~e brak~ shaft 4 is now mounted rotatively on the one side at 5 in the casing of 0 the transmission 2 and at the opposite end in the front region 6 of a beam projecting from the motor 1.
As indicated at 7 by a flange connection, the front portion 6 of the beam is releasable and removable and thereby also the bealing which is opposite to the driving connection of the brake shaft to the hollow shaft 3. As a result the 5 brake discs 8 provided on the brake shaft 4, if they are releasably fitted, can be readily removed res~ectively refitted to the bl~ke shaft 4 or, where appropriate, the entire brake shaft 4 including the brake discs 8 provided thereon can be disconnected .
The brake callipers 9 acting onto the brake discs 8, in order to avoid relative 2 o movements, are advantageously likewise fitted to the motor-transmission u~it 1, 2, but can also be fitt~d to the bogey chassis (not illustrated).

- 210~48 of a brake disc due to the mechanically substantially more stable two-sided mounting of the brake shaft 4.
An additional advantage results with the employment of the illustrated module in a dual axle power bogey, because due to the reduced distance between the 5 motor 1 and the hollow shaft 3 wi~in which the wheel set axle extends, a bogeycan be attained having a clearly reduced a~le spacing, which due to this short wheel base provides a clearly improved curve going ability.
The increased space requirement on that side of the hollow shaft 3 which is opposite to the motor 1 is of no importance, because that space in conventional 0 bogeys is largely unu~lised.
