Braked, touch on the brake pedal when, hydraulic system pushes brake block to brake rim, after decontroling pedal, brake block return.
Since the loading capacity of large and medium-sized truck is larger, the inertia force generated in driving conditions is big, vehicle need it is longer away from
It needs to step on brake for a long time from can just check, or in order to control speed, for example driver will step on always when lower long slope
Brake, complete slope is just dared to decontrol under, otherwise just there is the danger of car crash, so allows for brake rim constant temperature liter
Height, degree of the height to rubescent damage wheel.In order to avoid such case, when Car design, is just provided with cooling water to braking system
Cold water is directly poured on brake rim by case.This is why the wheel one of truck is always seen in the place of highway climb and fall
The reason of road emits hot vapour, spreads water all the way.The cooling mode of this large amount of waterings is on the contrary effective to cooling down to brake rim.But this
A little large trucks are sprinkled water all the way, are got road surface wet, are increased the risk of other vehicle slips of vehicle, especially winter, road surface is easy to
Therefore it freezes, vehicle slip is out of control to be easy to occur.One vehicle large truck, which carries a large amount of cooling water, certainly will tie up it normally
Cargo capacity.
Even so, people still can when often see large truck because brake it is out of control due to rush at Emergency Vehicle Lane, or and its
The traffic accident that his vehicle rear-end collision collision causes.Reason cannot be replenished in time after being the water consume in water tank to the greatest extent mostly.According to tune
It looks into, brakes in the case of truck load, brake rim heating is especially fast, even if can be also raised in a few minutes with minimum speed traveling
At several hundred degrees Celsius, if watering cooling will blow out not in time, so the vertical code of danger shows after the water of water tank is finished.Watering
Although cooling can control temperature in a certain range, will be difficult to control when overload or long lasting for braking.
Therefore, there are many insecurity factors for existing drum type braking device, it is necessary to be improved.

Body pushes brake hoof to brake ring and generates frictional force brakes, and the hollow water cavity of crossing that the water in cyclic water tank is pumped into brake hoof through wheel cylinder carries out
The heat that friction generates is taken away in heat exchange, returns water tank after water outflow brake hoof, disperses part heat by pipeline, temperature is
It reduces, and then flows into radiator and continue to cool down, flow into brake ferrikinetics through wheel cylinder again after cooling, thus the heat generated when braking
It takes away in time rapidly, avoids the formation of high temperature, burn out parts.
The wheel cylinder of cooling water can link with brake system, the work when touching on the brake, and continue after decontroling brake pedal
Work a period of time stops again, so that remaining heat is taken away, can also work independently, be allowed to when driving and stop
Following period of time works after vehicle, adequately to cool.
Cooling water can be other coolant liquids, such as the common coolant liquid of engine etc..
The present invention is compared with existing drum brakes, and basic constitutive requirements do not become, but brake hoof, brake block and brake rim
