Description
Technical field
The present invention relates to a kind of inner-cooled brake system, in particular, more particularly to one kind can be prevented effectively from brake hub
The inner-cooled brake system too high with brake shoe temperature.
Background technology
Brake system steady operation in good condition and sustainable, is the key for determining traffic safety.Come for load truck
Say, its gross weight runs into descending section long up to tens of tons after loading goods, in order to ensure traffic safety, driver needs to step on
Firmly service brake is continuously braked.Continuous prolonged brake can cause the temperature of brake hub drastically to raise, the temperature of brake hub
Raise and reduce braking ability again, meanwhile, the brake hub of high temperature easily deforms or bursts, and the brake hub for bursting easily is blown up
Accident, increased the generation of road traffic accident.
In order to lower the temperature to the brake hub for heating up, many lorries are all additionally arranged spraying cooling system, are installed on lorry
One water tank（Usually 1 ton or so）, in the top of brake hub, spray head is set, when climb and fall section is run into, then open
Spray equipment, raises to ensure braking effect with the temperature for reducing brake hub under continuous braking conditions.It is this that brake hub is lowered the temperature
Mode, not only waste water resource, increased lorry deadweight, and sprayed again after brake hub temperature is raised, also easily
Aggravation brake hub deforms and bursts, and such as runs into the situation that water tank does not have water, it is impossible to ensure the safety of driving.
