Abstract
The utility model discloses an arresting gear for track transportation vehicles door system, a normal during operation of system keeps the braking clearance between stopper stator and the stopper rotor, and mutual independence when track transportation vehicles operation in -process, when the passenger misses the operation emergency release of operate door system inside, triggers earlier and separates the lock -switch, and a door system sent the brake singal this moment, and messenger arresting gear works, and a door system can't open and shut, guarantees passenger's safety, when the train was allowwed to be opened the door, the door system cut off the power supply to arresting gear, forfeiture braking effect, and simple structure, simple to operate, arresting gear independently exist, and the convenience is maintained and is changed, practices thrift the maintenance cost, has good application prospect.
Description
Technical field
This utility model belongs to rail traffic vehicles component technology field, is specifically related to a kind of brake unit for rail traffic vehicles door system.
Background technology
Brake unit is rail traffic vehicles door system operating important safety parts, for braking the drive mechanism of door system, it is ensured that passenger safety.Applying the brake unit on rail traffic vehicles door system to be all integrated in driving motor at present cannot separately maintain, once brake unit or driving motor are damaged, and need integral replacing, cause maintenance cost to increase.And be integrated in and drive the brake unit braking torque in motor little, and the plastic gear driving motor is caused great impact by braking suddenly, is easily damaged driving motor, affects motor service life.
Utility model content
This utility model is solved the technical problem that it is to overcome existing brake unit to be all integrated in driving motor, it is impossible to separately maintains, and brakes suddenly the plastic gear to driving motor and cause great impact, is easily damaged the problem driving motor.
In order to solve above-mentioned technical problem, this utility model be the technical scheme is that
nullA kind of brake unit for rail traffic vehicles door system，It is characterized in that: include fixed support、Brake stator、Brake rotor、Connecting shaft、Axle sleeve、First angular contact bearing、Adjust pad、Flat key，Described fixed support is arranged on the outside of driving means，The connecting shaft connecting driving means extends support bracket fastened side board，Described brake stator is fixed on the outside of fixed support side board，And be socketed in connecting shaft，On the first angular contact bearing that described axle sleeve is arranged between connecting shaft and brake stator，It is nested with brake rotor outside described brake stator，Adjustment pad it is provided with between described brake stator and the end face of axle sleeve，For adjusting the brake clearance between brake stator and brake rotor，The inner ring of described brake rotor is fixed on the front end of connecting shaft by flat key，Ensure brake rotor and connecting shaft synchronous axial system，It is provided with the second angular contact bearing between rear end and the fixed support of described connecting shaft，Described connecting shaft pushes down the inner ring of the second angular contact bearing，Described brake rotor pushes down axle sleeve by adjusting pad，The first angular contact bearing inner ring pushed down by described axle sleeve，Described first angular contact bearing、Second angular contact bearing can be to eliminate axial gap，Ensure the brake clearance between brake stator and brake rotor.
It is previously described for the brake unit of rail traffic vehicles door system, it is characterised in that: also including hex nut, described hex nut twist-on is in the front end of connecting shaft.
The beneficial effects of the utility model are: the brake unit for rail traffic vehicles door system of the present utility model, when door system normally works, brake clearance is retained between brake stator and brake rotor, separate, when in rail traffic vehicles running, when there being the operation emergency release within passenger's maloperation door system, first triggering and solve lock-switch, now door system sends brake signal, makes brake unit work, door system cannot folding, it is ensured that passenger safety；When train allows to be opened the door, door system carries out power-off to brake unit, loses braking effect, simple in construction, and easy for installation, brake unit is individually present, and maintains easily and changes, and saves maintenance cost, has a good application prospect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the brake unit for rail traffic vehicles door system of the present utility model.
In accompanying drawing, the implication of labelling is as follows:
1: fixed support；2: brake stator；3: brake rotor；4: connecting shaft；5: axle sleeve；6: the first angular contact bearings；7: adjust pad；8: flat key；9: hex nut；10: the second angular contact bearings.
Detailed description of the invention
Below in conjunction with Figure of description, this utility model is further described.
As shown in Figure 1, brake unit for rail traffic vehicles door system of the present utility model, including fixed support 1, brake stator 2, brake rotor 3, connecting shaft 4, axle sleeve 5, angular contact bearing 6, adjust pad 7, flat key 8, hex nut 9, described fixed support 1 is arranged on the outside of driving means, the connecting shaft 4 of described driving means extends the side board of fixed support 1, described brake stator 2 is fixed on the outside of fixed support 1 side board, and be socketed in connecting shaft 4, on the first angular contact bearing 6 that described axle sleeve 5 is arranged between connecting shaft 4 and brake stator 2, it is nested with brake rotor 3 outside described brake stator 2.
nullAdjustment pad 7 it is provided with between described brake stator 2 and the end face of axle sleeve 5，For adjusting the brake clearance between brake stator 2 and brake rotor 3，The inner ring of described brake rotor 3 is fixed on the front end of connecting shaft 4 by flat key 8，Ensure brake rotor 3 and connecting shaft 4 synchronous axial system，Described hex nut 9 twist-on is in the front end of connecting shaft 4，It is provided with the second angular contact bearing 10 between rear end and the fixed support 1 of described connecting shaft 4，Described connecting shaft 4 pushes down the inner ring of the second angular contact bearing 10，Described brake rotor 3 pushes down axle sleeve 5 by adjusting pad 7，The first angular contact bearing 6 inner ring pushed down by described axle sleeve 5，Described first angular contact bearing 6、The axial gap that second angular contact bearing 10 can cause because of part tolerance with elimination，Ensure the brake clearance between brake stator 2 and brake rotor 3，Gap between stator 2 and the brake rotor 3 of now brake is ensured by the quantity adjusting packing ring 7.
Brake unit for rail traffic vehicles door system of the present utility model, work process is as follows, when door system normally works, brake clearance is retained between brake stator 2 and brake rotor 3, separate, when in rail traffic vehicles running, when having the operation emergency release within passenger's maloperation door system, first trigger and solve lock-switch, now door system sends brake signal, brake unit is made to obtain electric work, the Inside coil of brake stator 2 produces powerful magnetic force and overcomes in brake rotor 3 strength of leaf spring by the armature adhesive on brake rotor 3, realize braking function, braking effect may be adjusted by adjusting the position of packing ring 7, door system cannot folding, guarantee passenger safety；Door system carries out power-off to brake unit, and brake stator 2 resets with brake rotor 3, loses braking effect, retains brake clearance, it is achieved release braking function.Brake unit for rail traffic vehicles door system of the present utility model, simple in construction, easy for installation, brake unit is individually present, and maintains easily and changes, and saves maintenance cost, has a good application prospect.
