Description
Technical field
The utility model is related to rail traffic vehicle braking field more particularly to a kind of electronic folding auxiliary brakings
Plate.
Background technology
For urban rail transit vehicles, in order to which running rail traffic vehicles is enable promptly to slow down or stop
Vehicle, it is necessary to implement and brake to it；In order to prevent rail traffic vehicles on gug run when due to the weight of rail traffic vehicles
Power effect causes rail traffic vehicles speed to increase, it is also desirable to it be implemented and braked；It is to avoid parked vehicle because of gravity simultaneously
Effect or wind blows and car slipping also need to implement braking to it.It is installed for rail traffic vehicles is enable to implement to brake and alleviate
A whole set of device on rail traffic vehicles, collectively referred to as rail traffic vehicle braking device.The important function of brake apparatus exists
In：On the one hand rail traffic vehicles is made to slow down or stop under any circumstance, it is ensured that traffic safety；On the other hand it is also to improve rail
The road vehicular traffic speed of service improves trailing weight, so as to improve the important means of rail vehicle transportation ability, for ensureing rail
Road vehicular traffic high speed, loading, safe operation have vital meaning.
Current urban rail transit vehicles service braking mode is：Block brake and disc braking；
Although Block brake has the advantages that very much, it also has a great impact to wheel, embodies a concentrated reflection of following feelings
Condition：
(1) heat cracks
(2) the trench abrasion of wheel
(3) the spill abrasion of wheel
Disc braking biggest advantage is that thermal diffusivity is good, speed height, carrying when this runs for urban rail transit vehicles
More, the frequent driving feature of startup braking, acts on more safety guarantee.But after disc braking replaces Block brake, make wheel
Adhesion coefficient between rail is declined, and is unfavorable for the safe operation of rail traffic vehicles.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of rail traffic vehicles folding auxiliary brakings
Plate on the basis of existing braking strategy is constant, in addition adds auxiliary braking device and provides additional braking force, for alleviating or
Improve the deficiency of existing braking strategy.
The utility model is achieved through the following technical solutions：
A kind of rail traffic vehicles folding auxiliary braking plate, it is characterised in that：Including windage brake plate, pleat canopy and drive

Nogata is fixed on the left side or right side of windage brake plate to either its bevel edge of opening sealing is collapsed, and right angle base is fixed on peace
Fill bottom portion of groove.When rail traffic vehicles are in operating condition, pleat canopy is in compressive state, collapses the installation groove in roof
It is interior；When rail traffic vehicles are in damped condition：With the rising of windage brake plate, pleat canopy is gradually opened, on windage brake plate
It is also that pleat canopy is in opening greatest limit state when rising maximum height.Pleat canopy forms a semi-enclosed windage with windage brake plate
Braked space will generate great resistance in air inflow space, these resistances are exactly the braking needed for rail traffic vehicles
A power part；Canvas pleat canopy rain-proof, anti-gray, dust-proof etc. are functional, can extend the service life of complemental brake system；It collapses in vehicle
When pushing up in installation groove, moreover it is possible to play the role of vibration isolation and damping, can prevent due between rail traffic vehicles vibrations, auxiliary braking plate
Mechanical part occur friction or collision.
Further, the supporting rod erects section end as spheric end, and sphere diameter erects a section appearance and size more than supporting rod, is oriented to
Slot erects a section shape with supporting rod close to the top vallecular cavity of notch and matches, and guide groove is close to the lower part vallecular cavity and supporting rod of slot bottom
Spheric end matches.The fit structure of spheric end and guide groove, it is ensured that T shapes supporting rod can steadily be slided in guide groove
It moves and will not fall off.
Further, the spheric end erects section rotation connection with supporting rod, and spheric end can be rotated around the centre of sphere.Ensure to support
Bar smooth sliding can be not stuck in guide groove.
Further, lubricating cream is filled between the support boom end and guide groove, ensures supporting rod in guide groove
Smooth sliding, prevent stuck.
Further, the supporting rod quantity is two, is respectively arranged at windage brake plate bottom arranged on left and right sides, is supported
Guest's balance is more preferable.
Further, the motor output shaft is equipped with brake, and motor output shaft passes through reduction gear box and supporting rod
Connection.Drive mechanism is reliable and stable, convenient for controlling output speed.
Further, the upward maximum flip angle of the windage brake plate 1 is 25 °~30 °, the too small influence windage of angle
Decelerability, the excessive windage of angle is excessive, easily leads to the damage of auxiliary braking plate.
The beneficial effects of the utility model are：
1st, the design is on the basis of the rail vehicle technology of current city, and design adds part band brake function part
Part, increased brake component can not only provide additional braking force in braking, at the same time can also the system of saving to a certain extent
Dynamic consumed energy, caused environmental pollution when reducing traditional braking component working is energy-saving and environment-friendly, and does not interfere with
The external ornamental value of vehicle；
2nd, complemental brake system, as its name suggests, i.e., rail traffic vehicles are original in rail traffic vehicles in damped condition
The windage generated on the basis of braking strategy by machinery provides additional braking force for rail traffic vehicles, although the auxiliary system provided
Power cannot account for leading role, but its brake force generated is greatly saved rail traffic vehicles and generates brake force by other parts
The energy consumed, has saved financial cost, also reduces environmental pollution, kills two birds with one stone.
3rd, the utility model also has many advantages, such as that use cost is low, facilitates popularization and application, and the market with conspicuousness is applied
Value.
