Abstract
The utility model relates to an empty and load automatic brake device for a railway freight car, which comprises a base plate, a sensing valve, a bracket, a suppression disc, a reset spring, a decompression air cylinder and a pressure limiting valve, wherein, the reset spring is sheathed on a cylinder of the suppression disc; the pressure limiting valve is composed of an intermediate body, a copper sheathing, a wafer and a minor axis. The utility model reduces and relieves the influence of upper and lower vibration to measurement when the railway freight car runs and increases the weight measuring precision of the sensing value to make the railway freight car remain the maximum balancing pressure of the full service braking of a brake.
Description
The utility model relates to a kind of setting device of rolling stock, especially a kind of railway truck adjustment device of empty weight/heavy weight.
The railway truck adjustment device of empty weight/heavy weight is a kind of control setup on the rolling stock, referring to Fig. 1, on the railway truck adjustment device of empty weight/heavy weight in the prior art, there is following defective: when full empty wagons position, the maximum decompression amount of full application of brake commonly used was 120Kpa when the train manage-style was pressed in 500Kpa, had dwindled the scope of service braking decompression amount 140Kpa; Check weighing system does not have damper mechanism, and glancing impact, transducer valve are subject to the influence of vehicle in the check weighing process.
The purpose of this utility model provides a kind of railway truck adjustment device of empty weight/heavy weight, overcomes the defective on the decompression amount in the prior art, by increasing the vibration damping means, makes transducer valve not be subjected to the influence of vehicle in the check weighing process.
For achieving the above object, the utility model is a kind of railway truck adjustment device of empty weight/heavy weight, comprise datum plate, transducer valve, support, inhibition dish, retracing spring, step-down reservoir and limiting valve, wherein, retracing spring is enclosed within on the cylinder of inhibition dish, and limiting valve is made of intermediate, copper sheathing, disk and minor axis, intermediate is arranged in the middle of the upper and lower cavity of former ratio valve body, at the intermediate center one copper sheathing is arranged, a minor axis passes this copper sheathing, and its upper end is fixed with disk to be one.
Advantage of the present utility model and characteristics are: owing to be provided with retracing spring, make the inhibition dish when moving up and down, reduce and the influence of up-down vibration when having alleviated vehicle operating measuring, improved the check weighing precision of transducer valve, the structure of limiting valve has not only kept the function of former adjustment device of empty weight/heavy weight, and make train at full empty wagons to any load-carrying of full weight car, the train blast keeps the maximum equilibrium of pressure 360Kpa of brake full application of brake commonly used when 500Kpa.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation of railway truck adjustment device of empty weight/heavy weight of the prior art;
Fig. 2 is the structural representation of railway truck adjustment device of empty weight/heavy weight of the present utility model.
Now contrast the best of description of drawings railway truck adjustment device of empty weight/heavy weight of the present utility model
Embodiment.
As seen from Figure 2, the structure of railway truck adjustment device of empty weight/heavy weight of the present utility model, comprise datum plate 1, transducer valve 4, support 3, inhibition dish 5, retracing spring 2, step-down reservoir 11 and limiting valve 6, wherein, retracing spring 2 is enclosed within on the cylinder of inhibition dish 5, limiting valve 6 is made of intermediate 7, copper sheathing 8, disk 9 and minor axis 10, intermediate 7 is arranged in the middle of the upper and lower cavity of former ratio valve body, at intermediate 7 centers one copper sheathing 8 is arranged, one minor axis 10 passes this copper sheathing 8, and its upper end is fixed with disk 9 to be one.
In addition, datum plate 1 is installed on the bogie side frame of the bogie of car, and transducer valve is rack-mount, feeler lever makes progress, and the following card over against inhibition dish 5 is used for the load-carrying of measuring vehicle, and remove to drive limiting valve by the pressure air that enters the step-down reservoir, thereby, the air pressure that control enters brake cylinder.
