Abstract
The utility model relates to a pneumatic braking clearance automatic alarming brake air chamber. A moving contact and a travel switch are installed in a brake air chamber. A push bar slides to a critical range along with braking aeration. At the moment, an audible and visual alarm is triggered for reminding a driver to timely regulate. Thus, the good technical condition can be maintained. The utility model is simple, inexpensive and reliable.
Description
The utility model relates to car brake fastness mode of operation warning device.
High capacity waggon generally uses air braking systems at present, vehicle after new car or the maintenance just, gap between brake strap and the brake wheel mixes up by standard value, along with mileage increases, the brake plate wearing clearance increases gradually, and brake efficiency just weakens, for train operation accident hides some dangers for, according to China public security department data report, the reason of national on-highway motor vehicle accident, the bad proportion of brake condition is about more than 60%.Because brake clearance does not have demonstration, the gap exceeds standard and does not report to the police, and traffic safety does not have guarantee.
The purpose of this utility model provides a kind of compressed air brake cylinder that has the pneumatic brake device brake clearance energy auto alarm of acoustic-optic alarm.
The utility model is a compressed air brake cylinder bottom travel switch to be installed, push rod one end on the other side is adorned a moving contact, two contact pitch are critical stroke, and the push rod stroke is a forced stroke, and it is worth greater than critical stroke, stroke is the specific factor of brake clearance, effective critical value with critical stroke detection brake clearance meets or exceeds critical value, and two contacts are collided, circuit is connected, and triggers sound and light alarm immediately.
The utlity model has and eliminate accident potential, the function of guarantee driving safety reminds chaufeur in time to maintain the adjustment brake clearance, keeps the good technique situation at any time.
Description of drawings
Fig. 1 the utility model structural representation
As follows with reference to description of drawings:
A travel switch 5 is installed in the bottom of air chamber 10, push rod one end on the other side is installed an elasticity moving contact 7, travel switch wire joint combined aural and visual alarm 12, another termination storage battery 11 positive poles of annunciator, the storage battery negative earth, the gap of moving contact and travel switch is critical stroke 6, and the push rod stroke is a forced stroke 8, and forced stroke is greater than critical stroke.
When the braking inflation, diaphragm 9 compressing push rods 4 slide, and push rod forces adjusting arm 3 to rotate, and brake strap is adjacent to brake wheel, and brake clearance is zero, and the push rod stop advances, and moving contact does not contact with travel switch; When the brake collar severe wear, push rod continues to protract, and moving contact bumps travel switch, and circuit is connected, and sound and light alarm reminds chaufeur in time to adjust, and rotates adjusting worm 2 cam is rotated to an angle, to dwindle brake clearance, the value of maintaining the standard.As untimely adjustment, though push rod can continue to protract, idle travel increases, braking time lag, and wheel edge trig power descends, and poor stop is easy to accident.
Claims (1)
1, a kind of pneumatic brake gap auto alarm compressed air brake cylinder, comprise the leather cup 9 and the air chamber push rod 4 that are contained in the compressed air brake cylinder 10, it is characterized in that air chamber inside adorning a travel switch 5, a moving contact 7 is located on the push rod, pushrod movement touching travel switch, the big stroke detection brake clearance of push rod, travel switch line serial connection combined aural and visual alarm 12, another termination storage battery 11 positive poles of combined aural and visual alarm, negative earth.
