Description

Device to automobile brake drum, brake strip automatic water jetting cooling system

The utility model relates to the cooling technology and the neat and artistic technical field of car load outward appearance of load-carrying vehicle brake system.

Only consider to implement during owing to the design of former load-carrying automobile on conventional road surface with by the load carrying ability running condition of appraising and deciding, so as far back as 50, the sixties Fujian chaufeur just to former load-carrying truck in China torrid zone, mountain region, the subtropics highway gradient is big, brake strip often takes place when causing the loaded vehicle lower long slope to be burnt, brake wheel is rubescent, phenomenons such as brake shoe assembly and brake wheel locking; Solve truck in defective tropical, that mountain region, subtropics highway uses and invented the cooling of manual (the soil system) formula water spray.But this cooling spray system since be the cistern device of chaufeurs soil system on the operator's compartment top, and passenger vehicle is installed on it on the hood top, so that the car load outward appearance owe very much refined and carry on the back a very ugly burden more.This vehicle enters large, medium and small city proper, the utmost point influence the appearance of the city in city beautify, neatly, civilization uses the mode of automobile, just the outstanding China that influences uses the backward image of automobile the woods in the world, simultaneously because manual methods has many weak points, usually forget because of chaufeur and to open or close, forget out and above-mentioned fault may occur, forget that the pass causes water waste again, and adopt the manual methods water pipe just can through in the operator's compartment, cause the driving plate to rot again because of leaking, make the cooling mechanism complex structure, spillage of material is big, and reliability is low.

A kind of protective voltage type water storage tank and the pneumatic water injection valve of the electric time-delay magnetic control system of providing of the present utility model can be installed in it on chassis frame, to solve the device of the clean and tidy and manual many defectives of method of car load outward appearance; And to the equipped economic implications that very big Practical significance and market are arranged of the car load of car production producer.

The technical solution of the utility model is as follows: mainly by protective voltage type water storage tank and the pneumatic water valve two parts of electricity time-delay magnetic control, include an admission port 1 connection breather check valve 3 on the water tank.5 enter water storage casing interior resistance valve 6 with pressure regulating valve and air-pressure gauge 4 forms pressurization, pressurize and depressurized systems with the pressure-relief valve 7 on the filler cap; Water level sensor 8 is housed on the water tank links to each other, decompression inductor 9 polyphone decompression switch guide sounds, light alarm system and o-volt protection air feed pump 11 with limnimeter; Connect make-up water pump gas hand press valve with tracheae 2 on the limit port of admission port, pneumatic make-up water pump 13 adds joins; The coolant outlet pipe 14 of water tank links to each other with the admission port of the pneumatic water valve 15 of magnetic control, the admission port 16 usefulness tracheaes 17 of magnetic control pneumatic valve link to each other with brake activation valve 18 (automobile is original), direct current extending type electromagnet 19 usefulness electric wires 20 and digital display time relay (making delay timer), automatically with close the leading-out terminal that switches toggle switch 22, pressure switch 23 (for the original braking signal switch of automobile) and link to each other, the shower nozzle before and after water valve coolant outlet pipe 24,25 is connected to respectively on the bridge brake wheel (now for chaufeur soil system) composition is implemented the system that sprays water and cool off to autotruck brake wheel, brake strip.Brake activation valve when automobile brake (automobile is original) is opened for braking mode, electromagnetism gas.Valve is brought about the desired sensation, the conducting of pressure switch pressurized, and digital display time relay gets electric, automatically to the cooling of spraying water of brake wheel, brake strip, may break down and accident avoiding after certain hour time-delay.During brake off, brake activation valve (automobile is original) blocking-up, rapid release valve (automobile is original) exit fast release, the pneumatic water valve of magnetic control and brake system simultaneously rapidly return stop to spray water.Above technical scheme is seen Fig. 1.

Adopt such scheme, simple in structure, sensitive reliable, stable water pressure, water flow jet are strong, and finishing is convenient; And the truck of new generation of the utility car Assembling Production factory stock production torrid zone, the highway practicality of mountain region, subtropics puts on market, to fill up this blank of auto-industry technology.
