Embodiment
In one embodiment of the utility model, a kind of system of parking with monitoring parking brake status function is provided
Dynamic cylinder, referring to Fig. 1, the Parking Brake Cylinders include cylinder body 2, with the piston 4 of cylinder body cooperation, the mandril 6 being connect with piston and use
In the monitoring module of monitoring parking brake state, monitoring module includes being arranged on the position detection dress at the cylinder body upper inside wall
Put 1.
Preferably, the center of the piston 4 is equipped with the mounting hole coordinated with the mandril 6, i.e. mandril 6 is preferably provided at work
The centre position of plug, accordingly, the position detecting device 1 are preferably provided at the centre position at 2 upper inside wall of cylinder body.It is existing
Position detecting device is varied in technology, and the present embodiment is preferably contact-making switch.With movement of the piston 4 in cylinder body 2, band
Dynamic mandril 6 is done relative to cylinder body top closer or far from movement (being upper and lower directions in Fig. 1), and then makes mandril 6 and position detection
Device 1 has contact condition or off-state；On the other hand, the lower part of the mandril 6 passes through piston, when mandril 6 moves down
When, cylinder body is stretched out in the lower part of the mandril 6, resists service braking cylinder (not shown), and transmit and brake to service braking cylinder
Power.
Wherein, there are many brake force applying modes of Parking Brake Cylinders, apply including air pressure application, spring etc., this practicality
Novel that brake force applying mode is not construed as limiting, in order to which the technical solution of the utility model is better described, the present embodiment is preferred
By the way of the application of compressed spring 3, the upper end of the compressed spring 3 and 2 top of cylinder body are fixed, the compressed spring
3 lower part is fixedly connected with the piston 4.The Parking Brake Cylinders further include air pipe line interface 5, for being inflated into cylinder body
Or it is deflated outward by cylinder interior.
Parking Brake Cylinders concrete operating principle is as follows：
As shown in Figure 1, being inflated by air pipe line interface 5 into cylinder body 2, air pressure driving piston 4 moves upwards, and compresses bullet
Spring 3 is compressed by piston 4, and piston 4 drives mandril 6 to move upwards, and 6 top of mandril is contacted with contact-making switch, and mandril lower part is contracted completely
Into cylinder interior, Parking Brake Cylinders at this time do not export parking brake power, and monitoring module exports the first electric signal；
The release of gas part or release completely in cylinder body 2, as shown in Figures 2 and 3.In the stress of the compressed spring 3 of compression
Under effect, piston 4 moves downward, and then piston 4 drives mandril 6 to move downward, and 6 top of mandril (does not connect with contact-making switch disconnection
Touch), cylinder body is stretched out in mandril lower part, starts to apply parking brake power, then monitoring module exports the second electric signal；
In order to which using the electric signal of output, the monitoring module further includes signal display apparatus or software supervision system well
System (not shown), the contact-making switch are electrically connected with the signal display apparatus or software monitoring system, and the signal is shown

Software monitoring system carries out vehicle on-position by monitoring the activation signal of the generation of whole Parking Brake Cylinders in train
Judge.
For example, the signal display apparatus is display panel, when display panel shows the first electric signal, then illustrate mandril
6 tops are contacted with contact-making switch, i.e. Parking Brake Cylinders are in parking brake power complete incidence graph state (or even the display panel is straight
Connect the signal of display parking brake power complete incidence graph state)；When display panel shows the second electric signal, then illustrate on mandril 6
Portion disconnects the contact with contact-making switch, i.e. Parking Brake Cylinders are in the application of parking brake power (part applies or applies completely) state
(or even the display panel directly displays the signal that parking brake power part applies or applies state completely).In addition to display panel
Form, display lamp can equally realize the technical solution of the utility model, and the utility model is to the specific of signal display apparatus
Form is not especially limited.
In another embodiment of the utility model, based on above-mentioned Parking Brake Cylinders, further include and stop for hand relieving
Put brake force parks rod piece (not shown) manually, described to park rod piece manually and connect by mechanical mechanism with mandril 6.
When not starting manual parking mode, the mandril 6 links and (keeps opposing stationary) with piston 4；When starting manual parking mode,
Binding part between mandril 6 and piston 4 is mobile and unbinding by the rod piece of parking manually, and then mandril 6 is generated with piston 4
Relative motion, as shown in figure 4, specially mandril 6 is moved upwards relative to piston 4, until mandril 6 contacts (i.e. with contact-making switch
Parking brake power complete incidence graph).Specifically, the rod piece of parking manually can manually be stopped by pulling mode or way of propelling completion
Operation is put, monitoring module exports the first electric signal, and signal display apparatus shows parking brake power complete incidence graph.
In one embodiment of the utility model, additionally provide a kind of monitoring method of parking brake state, including with
Lower flow：
It is inflated by the air pipe line interface of Parking Brake Cylinders into cylinder body, to drive piston upwards, mandril lower part
Cylinder interior is fully retracted, mandril is contacted with contact-making switch, then monitoring module exports the first electric signal, and Parking Brake Cylinders do not export
Parking brake power, i.e. Parking Brake Cylinders are in parking brake power complete incidence graph state；
Air is released in cylinder body or part releases, under the stress for the compressed spring being compacted, the movement of piston countryside,
Mandril lower part, which is stretched out, parks outside cylinder, and mandril top is disconnected with contact-making switch, and contact-making switch exports the second electric signal, Parking Brake Cylinders
Start to export parking brake power, i.e. Parking Brake Cylinders are in the application of parking brake power part or apply state completely.
Operation parks rod piece manually, the mandril is made to be moved up relative to piston, the mandril lower part is fully retracted institute
Cylinder interior is stated, and then the mandril top connects switch contact with contact, then monitoring module exports the first electric signal, parking brake
Cylinder does not export parking brake power, i.e. Parking Brake Cylinders are in parking brake power complete incidence graph state.
Structure, the course of work and the monitoring principle of specific Parking Brake Cylinders have elaborated in the above-described embodiments,
Details are not described herein.
The utility model is described in detail above, its object is to allow the personage for being familiar with this field technology can be much of that
It solves the content of the utility model and is implemented, the scope of protection of the utility model can not be limited with this, it is all according to this practicality
