Description
Technical field
The present invention relates to vehicle brake technical field more particularly to a kind of energy-saving brake rim heat dissipations for heavy truck
Device.Solve that water drenching radiator water tank volume mass in the prior art is big, pipeline easily blocks, winter easily freeze caused by pacify
Full hidden danger, and energy conservation and environmental protection of the present invention, reliability are high.
Background technology
As the high speed development of Chinese national economy, the quick of high-grade highway are built, Logistics Market is to heavy type transport vehicle
Requirement it is higher and higher.High efficiency, high reliability, low cost, fast and safely the demand of advanced vehicle will increase substantially,
The brake load of vehicle also increases therewith simultaneously, especially to runing in the public transport of city incity, the long-term coach for running hill path, card
For the medium-weight vehicles such as vehicle, brake problem is especially prominent.
Currently, mainly using two ways on the brake problem of medium-weight vehicle.First way is by middle heavy
Retarder is installed to reach braking effect on type vehicle, main retarder to be used is Retarder.Retarder is determined
Son is again retarder shell, is connect with speed changer rear end or vehicle frame, rotor is connected by hollow shaft with transmission shaft, rotor and stator
On cast out blade.Operation principle is：Apply pressure to oil sump by means of the manipulation of control valve, working solution is made to fill people's rotor and determine
In working chamber between son.One torque is acted on to stator by working solution when rotor rotates, and the countertorque of stator becomes
The braking moment of rotor, value depend on the rotating speed of the liquid measure and pressure and rotor in working chamber.Automobile kinetic energy is consumed in work
Make the friction of liquid and thermal energy is converted to the impact of stator, working solution temperature is made to increase.Working solution is introduced into heat exchanger
It circulates, heat is transmitted to cooling water, then shed by engine-cooling system.Retarder can reach all well and good braking effect
Fruit, but appoint so there are two main shortcomings：1, fancy price；2, the engagement of brake and segregation lag time are long, no
There is power loss when work, is especially used for for machine driving automobile complicated when trailer.So as to cause retarder in
The utilization rate of state is not high.
The second way is to reach braking effect by the brake system in medium-weight vehicle, and brake system is by means of stopping
Vehicle is roused with brake block friction to play the effect of braking, and this friction will produce a large amount of heat, of low cost, braking effect
Fruit is apparent, is the most of vehicle modes selected to use of China, but this mode of braking can lead to brake hub and brake block mistake
Heat, to cause Vehicle Driving Wandering, sideslip unstability and blow out etc., a series of accidents, consequence are hardly imaginable.For prevent brake gear because
It overheats and loses braking ability and then need good cooling device.
In order to cool down to brake system, most of drivers are cooled down using water drenching mode.Water drenching brake modes are main at present
There are four types of：1, gravity flow：Water tank aloft, using the dead weight of water makes flow to each tire.2, vapour-pressure type：Water tank is generally big
Liang Shang, the air pressure generated using the air compressor machine of vehicle self-carrying, water is sent to nozzle, and the flow of water is controlled using water valve.3, air pressure
Formula (solenoid valve control)：This mode is substantially identical as upper one kind, and control valve has only been changed into solenoid valve, and arrangement is simpler.
4, water pump type：Water tank is equally mounted on crossbeam, does not need air pressure at this time, but hydraulic pressure is gone out using water pump, it is only necessary to
Switch control water pump.Above-mentioned four kinds of modes are as follows there are common defect：1, water storage tank volume and quality are all very big, shape
It is largely wasted at very big security risk and lorry oil consumption increase, water resource；2, watering cooling mode has centainly the brake rim service life
It influences；3, pipeline and icy on road can be caused when temperature is below the freezing point, and cause driving dangerous, some areas have been prohibited
Use in winter water drenching device；4, sometimes water drenching pipeline blockage or water consume is complete does not add in time, can cause prodigious danger, stop
The long-term friction brake drum of vehicle piece, causes brake block weak, and brake rim is impaired, and braking efficiency substantially reduces, and brake force is almost lost,
To lose control of one's vehicle, car crash.
In view of the above problems, a kind of novel lorry radiator of design is very urgent.
