Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.Following examples will contribute to those skilled in the art and understand the present invention further, but not limit the present invention in any form.It should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, some distortion and improvement can also be made.These all belong to protection scope of the present invention.
Based on heavily card quality is huge, operating personal carries out blind operation in the operator's compartment outside the nearly 20m, and be difficult to accomplish the accurate location in heavy card motion process and braking in time, practice shows that the most practical failure-free method utilizes original brake device in vehicle.Be based on the recognition just, the present invention by solenoid control pneumatic valve, then by pneumatic valve driving brake connecting rod, forms electronic gas that a service brake and computing machine (or RF remote-controlled) control and to stop complementary system.Gas circuit design has arranged a special gas circuit from high pressure tank, and does not do any variation to original gas circuit, so both can ensure the pressure of electronic gas circuit, not affect again the normal running heavily blocking original service brake part.
As shown in Figure 1, the present embodiment provides a kind of heavily card pneumatically operated brake based on wireless remote control, comprise brake gas circuit, brake machinery device and the wireless remote controller based on radio frequency, brake gas circuit connects brake machinery device, wireless remote controller based on radio frequency realizes wireless remote control braking by brake gas circuit driving brake mechanical device, wherein: brake gas circuit is that one section of H-L-M-N in parallel is new on the basis of original brake gas circuit electricity is stopped gas circuit; Brake machinery device on original service brake connecting rod 6, arranges an electricity to stop connecting rod 5, at the stop end of connecting rod 5 of electricity, a block arc 9 is set, in work, automatically controlled signal controls high pressure draft by electromagnetic valve 2 and drives pneumatic valve 3, is promoted electricity connecting rod 5 of stopping completed braking by the guide rail 4 of stopping of the electricity on pneumatic valve 3; Wireless remote controller adopts the remote control decoding integrated circuit of high reliability, low-power consumption, sends electric signal Controlling solenoid valve 2 by radiofrequency signal 12 by signal receiving device 13, realizes the accurate braking heavily blocked.
As Fig. 1, 2 are depicted as the present embodiment brake gas circuit apparatus structure schematic diagram: in order to not affect original brake gas circuit, the electricity that one section of H-L-M-N in parallel is new on original basis is stopped gas circuit, admission port H connects high pressure tank 1, L connects the import of motor-operated control valve 14, M connects the outlet of motor-operated control valve 14, N connects the admission port 10 of pneumatic valve 3, in order to ensure independence and the reliability of system, admission port H connects high pressure tank 1 and original brake of getting along well shares a source of the gas, ensure that electronic auxiliary brake system can not affect original service brake and hand-braking system, namely artificial braking and assist brake are that two cover independent parallels are independent of each other, to guarantee the reliability of system.
Be illustrated in figure 3 the present embodiment brake machinery apparatus structure schematic diagram: I figure is front view, II figure is the G direction view of front view, and wherein electricity connecting rod 5 of stopping is fixed on pedal connecting rod 6; Electricity stops guide rail 4 for being connected to the two pieces of metal sheets (forming a guide rail style) on pneumatic valve 3, and connecting rod 5 of being stopped by electricity is arranged on electricity and stops and play the effect of " knot that can be undone by a pull " between guide rail 4; 3 is pneumatic valve; 10 is the admission port of pneumatic valve 3; In order to prevent electricity from stopping connecting rod 5 moves time to stop the alerting ability skidding off between guide rail 4 and guarantee when moving up and down simultaneously from electricity, weld a block arc 9 at the stop end of connecting rod 5 of electricity.
When stepping on brake, service brake pedal 7 moves downward, and to be stopped connecting rod 5 upward movement by leverage electricity; Because electricity guide rail 4 of stopping is that thus " knot that can be undone by a pull " structures of two pieces of metal sheets does not affect the artificial braking of chaufeur completely; When auxiliary brake system triggers braking, control system sends brake signal, admission port 10 air inlet of pneumatic valve 3, and pneumatic valve 3 upwards jack-up electricity connecting rod 5 of stopping drives service brake pedal 7 to move downward, and car brakeing is almost just the same with the process stepping on service brake pedal 7; When reset brake signal, release high pressure gas, electricity connecting rod 5 of stopping is followed electricity guide rail 4 of stopping and is moved downward, and drives service brake pedal 7 to reset.
The present embodiment wireless remote controller adopts the universal remote control decoding integrated circuit of high reliability, low-power consumption, sends electric signal with Controlling solenoid valve 2 by radiofrequency signal 12 by signal receiving device 13, thus the accurate braking that realization heavily blocks; This device adopts CMOS technology manufacture, and actv. decreases the conflict of code and illegally scans to make it the possibility of coupling to coding; This device adopts the radio frequency chip of high reliability simultaneously, frequency 315KHz, transmission distance is greater than 100m, has that bite is strong, reliability high, wireless signal output relay contact current reaches 20A (125V), can ensure the reliability requirement that system drives electromagnetic valve 2 completely.
In the present embodiment, electromagnetic valve 2 working power uses vehicle-mounted 24V storage battery, in order to ensure the reliable and stable of system, implements voltage stabilizing isolation processing to power supply.
The present invention transforms heavy lorry brake device, design specialized pneumatic circuit is by solenoid control pneumatic valve, simulate artificial braking mechanism, realize the accurate braking heavily blocking moment, this device has that structure is simple, reliable and stable, lower-price characteristic, and the computer controlled of card of attaching most importance to provides the actuating unit of high reliability.The wireless remote controller that the present invention uses adopts the radio frequency chip of high reliability, can carry out long-distance remote control brake by operating personal.Simultaneously automatically controlled gas system of stopping is separate with original service brake system, does not interfere with each other, and manually brakes and forms the relation of a "or" between electric brake, substantially increasing the reliability of emergency brake.
