Abstract

The utility model provides an electric water spraying and cooling device for a vehicle brake drum and a vehicle brake friction sheet, which is an electric water valve controlled by an electromagnet. The utility model is mainly composed of a water tank, an electric water spraying valve, a switch for a vehicle brake lamp, a manual electric switch, a water pipe, an air pipe and a circuit. As long as the manual switch is shifted under a conducting state, when a driver brakes a pedal for brake, a vehicle is braked, the electric water spraying valve is simultaneously automatically opened for spraying water on the brake drum and the brake friction sheet for cooling and protecting the brake friction sheet and the brake drum, and probably faults or probably accidents are avoided. The utility model has the advantages of simple structure, sensitivity, reliability, convenient installation, and convenient repair.

Description

To automobile brake drum, brake strip electrical water jetting cooling mechanism

The utility model relates to the cooling technology field of load-carrying vehicle brake system.

As far back as 50, sixties Fujian chaufeur to the heavy cargo car of publishing originally 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, the cooling of (soil is done) formula water spray solves the load-carrying lorry in the torrid zone and invented manually, the defective that mountain region, subtropics highway uses, but this cooling spray system is owing to be chaufeurs soil system, its effect is undesirable, because manual methods has many weak points, chaufeur is usually forgotten the open type pass, forget out and above-mentioned fault may occur, forget that the pass causes water waste again, and employing manual methods water pipe palpus can through operator's compartment, this makes the cooling mechanism complex structure, and spillage of material is big.

The purpose of this utility model provide a kind of can be when automobile brake, automatically to the spray water device of cooling of brake wheel, brake strip.

The technical solution of the utility model is as follows:

The main dynamoelectric water valve that adopts the control of driving DC electromagnet, system comprises that mainly water tank 1 (automobile is original) is connected water pipe 2 with water valve, dynamoelectric water valve 3,4, water valve coolant outlet pipe 5,6, circuit electric wire 7,9 with manual, automatic transfer switch 8 and braking signal switch 10 (automobile is original) are formed, to have 5 on the water valve, before and after 6 two coolant outlet pipe are communicated to respectively in the bridge brake wheel to the cooling of spraying water of brake wheel and brake strip, two of the magnet coils of electrical water jetting valve, wherein one is connected on the vehicle frame and is ground wire, and the manual button switch of another root electricity consumption bundle of lines (be installed in the operator's compartment as manually with automatically switch) is connected to the leading-out terminal of braking brake light switch.Accompanying drawing 2,5 is the block diagram of the utility model dynamoelectric water valve, is that inner each position of components of dynamoelectric water valve is static blocking-up among Fig. 3,4,6,7.When automobile brake, the automobile brake stoplight stop lamp is bright, magnet coil that electromagnetism promotes water valve simultaneously, moving armature upward movement under the magnetic field force effect promotes water injection valve and opens automatically, immediately water is sprayed in the brake wheel and cool off, behind brake off, the braking brake switch turn-offs, and then the electrical water jetting valve also cuts out.

Adopt such scheme, simple in structure, sensitive reliable, it is convenient to save the water source finishing.

Be illustrated below in conjunction with drawings and Examples:

Fig. 1 is the utility model fundamental diagram;

Fig. 2 is the utility model single-chamber type electrical water jetting valve schematic appearance;

Fig. 3 is the inner structure scheme drawing of Fig. 2;

Fig. 4 is the center symmetry cross-sectional schematic of Fig. 2;

Fig. 5 is the utility model bicavate electrical water jetting valve schematic appearance;

Fig. 6 is the inner structure scheme drawing of Fig. 5;

Fig. 7 is center, the wherein chamber symmetry cross-sectional schematic of Fig. 5.

As shown in Figure 1: the utility model is by water tank 1, water pipe 2,5,6, electrical water jetting valve 3, electromagnet assembly 4, electric wire 7,9, manually toggle switch 8 (be manually with the usefulness of automatic switchover), braking brake light switch 10.The water inlet of electrical water jetting valve is connected with water outlet of water tank water pipe 2 (being the water injection valve coolant inlet pipe), and the electrical water jetting valve has two water outlets difference water pipes 5,6 (being two coolant outlet pipe of water injection valve) to connect the interior frictional position of aiming at brake wheel and brake strip of brake wheel of back axle forward; Two pig-tail wires of the magnet coil of electrical water jetting valve, wherein directly receive on the vehicle frame and to be ground wire for one, another root is received manual toggle switch 8 in the operator's compartment (be installed in help driver's operation in the operator's compartment and be convenient to manually and the using of automatic switchover) is connected to the braking brake light switch again with electric wire 9 leading-out terminal to it with electric wire 7.When the chaufeur pin is stepped on braking footrest, automobile brake, stoplight stop lamp is bright, and the electromagnetism wire frame of electrical water jetting valve is also switched on simultaneously, opens automatically, and water sprays to brake wheel and brake strip immediately, when brake off, also stop water spray synchronously with brake light, brake system.

The utility model can be installed in each parts on the position suitable on the vehicle frame according to actual conditions when installing, and this is easy to accomplish.

As Fig. 2 Fig. 3 and shown in Figure 4, this single-chamber type electrical water jetting valve is mainly by shell 11, spool 12 in the water cavity, be enclosed within on the spool top, and be pressed in pull back spring 13 on the water cavity top bottom face, a water inlet 14 is arranged on the shell 11, two

water outlets

15,16, use Luo silk 17 bonded assembly driving DC electromagnet assemblies 18 on the water injection valve large end face, electromagnet moving armature push rod 19, when static, spool is a virgin state under the effect of pull back spring pressure, O RunddichtringO 20 is to advance, this carrier frequency channel break of water outlet, O RunddichtringO 21, the armature chamber of water cavity and electromagnetism is kept apart O RunddichtringO 22, be to prevent water inlet in the pull back spring chamber.When automobile brake, the electromagnet energising, moving armature is upward movement under the magnetic field force effect, its push rod promotes to move on the spool, thereby connection intake-outlet, water are gone in the brake wheel the cooling of spraying water of brake wheel and brake strip by water outlet automatically, and during brake off, the electromagnet dead electricity does not have magnetic field force, and pull back spring return at once makes spool get back to original blocking state.

Shown in Figure 7 as Fig. 5 Fig. 6, this bicavate electrical water jetting valve is compared with single-chamber type, and many sleeving valve core mechanisms should have two water inlets and two water cavities mutually, and principle of work is the same, so describe in detail slightly.
