Description
Technical field
The present invention relates to brake apparatus, and in particular to a kind of energy-saving transmission shaft brake apparatus.
Background technique
When vehicle especially loads the descendings such as lorry, the automobile of weight or emergency brake, if brake apparatus is insensitive, it will face
Very big danger.The vehicles such as current lorry, automobile only have there are two brake apparatus, i.e., before stop and rear brake.When one of system
Dynamic device when something goes wrong, only relies on a brake apparatus and is extremely difficult to control the effect of car speed very well.Vehicle is being run
In speed it is directly proportional to rotating speed of transmission shaft, that is, control shaft speed and just control car speed.Vehicle is mainly at present
Pass through the control of engine, transmission shaft and gear-box three completion speed.Based on this, the present invention devises a kind of energy-saving transmission shaft
Brake apparatus increases brake apparatus of the invention newly that is, in the case where original brake apparatus retains, and is applied in vehicle.And it is right
Originally brake sequence is overturned, original rear brake (main brake) only a small amount use now, is stopped based on the present invention is preferential.
Summary of the invention
The present invention provides a kind of energy-saving transmission shaft brake apparatus, by adding drum in drum brake on transmission shaft, to increase
Transmission shaft outer diameter area.It rouses with corresponding anchor ear friction using in drum brake to reach braking effect.In transmission shaft and drum brake

Stability.Transmission shaft is driven by descending excess energy, and transmission shaft is with hydrodynamic pressure or electrical energy devices, thus for direction of fall
It is fuel-efficient to achieve the effect that vehicle descending can turn off the light for kinetic energy needed for oil hydraulic power and brake apparatus needed for disk.
The technical solution of the present invention is as follows:
A kind of energy-saving transmission shaft brake apparatus, including hydraulic device, transmission shaft and vehicle crossbeam connection frame, the hydraulic dress
It sets and is driven axis connection, make transmission shaft that the extra power of descending is passed to hydraulic device；Transmission shaft one end and vehicle motor
Connection, the other end are connect with driving rear axle；Transmission shaft is equipped with drum in drum brake, and vehicle crossbeam connection frame passes through cold with drum in drum brake
But water conduit connects, and drum is equipped with braking anchor ear system in the drum brake, and vehicle is made to pass through drum in braking anchor ear system and drum brake
Friction reach braking effect；It further include cooling system, drum connects in cooling system and vehicle crossbeam connection frame, drum brake.
Further, the belt and be driven axis connection that the hydraulic device is driven by belt pulley.
Further, the outer diameter of drum is 12-40 centimetres in the drum brake, and length is 40-200 centimetres.
Further, the braking anchor ear system is made of braking anchor ear, and the braking anchor ear system passes through electromagnetism, hydraulic
Or the bulging frictional force size with friction facing in the elastic control drum brake of checking cylinder is realized in air pressure.
The braking anchor ear number braked in anchor ear system can be 1-6, and set braking anchor ear number is according to vehicle reality
The setting of border situation, using operation, by driver, such as road surface sight, the gradient, load-carrying decide whether to press braking according to the actual situation
Cylinder controls in moderating process, and drum in 1 or 1 or more braking anchor ear and drum brake can be used and carry out friction eceleration, pass through classification
Braking, makes to brake more stable.Such as when setting braking anchor ear is 5, when anchor ear is braked in triggering first, reduction of speed 20%；Triggering the
When two braking anchor ears, reduction of speed 40%；When triggering third braking anchor ear, reduction of speed 60%, and so on.If an emergency situation is encountered, 5
It triggers together.Braking anchor ear is connect with driver's cabin by signal wire, or is connect with service brake, can be passed through to the triggering of braking anchor ear
Signal wire carries out in driver's cabin, or is triggered by service brake.
Further, the braking anchor ear includes shoe brake, return spring, checking cylinder and friction facing, shoe brake
It connect with friction facing, is formed for guaranteeing that the radian of friction facing reaches in drum brake drum outer surface with friction facing CONTACT WITH FRICTION
Best rubbing surface；Checking cylinder is connect with shoe brake, and the both ends of return spring are connect with checking cylinder, for realizing checking cylinder
Elastic return.
Further, the checking cylinder is connected by threeway with the original electromagnetism of vehicle, hydraulic or pneumatic shuttle, or with this
The hydraulic device of invention connects, and carries out signal connection with driver's cabin.
Further, the shoe brake is made of two semicircles, and it is big that described two semicircles are bolted to vehicle
On beam connection frame, the power for that will brake drum generation in anchor ear and drum brake is transferred to vehicle crossbeam connection frame and plays braking effect
Fruit.
Further, cooling system includes cyclic water tank, cooling water inlet, coolant guide pipe, recirculated water cavity and cooling
Water out；Cyclic water tank is equipped with water outlet, water inlet and with leachy lid, and wherein water outlet is located under cyclic water tank
Portion, water inlet are set to the top of cyclic water tank, and water outlet is connect with cooling water inlet by water pipe, cooling water outlet and recirculated water
The water inlet of case connects；
Cooling water inlet is set on vehicle crossbeam connection frame, and cooling water, through vehicle crossbeam connection frame, leads to from cooling water inlet
Supercooled water conduit flows into recirculated water cavity, finally flows out to cyclic water tank from cooling water outlet.
Further, it is equipped with bearing in vehicle crossbeam connection frame, drum in drum brake is freely rotated.

The invention has the benefit that
1, much local winter forbids vehicle descending watering cooling wheel hub in China, worries icy on road more dangerous.And this hair
Bright improvement rear braking system is recirculated water, will not be sprinkled water to road surface.
2, after wheel hub and friction facing rub for a long time, temperature can be to 400 DEG C or so or higher, and slope is longer, and temperature is higher,
And it sprinkles water be possible to cause wheel hub explosion at this time.After improvement, due to having used cooling water circulation, maximum temperature is no more than 100 DEG C,
Normal is 50-60 DEG C, thus guarantee again big slope temperature be also it is constant, thus provide the stable guarantee of temperature.
3, conventional brake is exactly interior drum installation friction plate, and friction area can not extend.The present invention passes through on setting transmission shaft
Drum brake in drum and braking anchor ear in friction facing, so that the friction area of transmission shaft is extended, with further improvements brake
Effect.
Once 4, conventional brake high temperature failure car crash.High temperature is not present by increasing cooling system, brake in the present invention
The case where failure；Even if failure one, there are also the complete brake system of other set equally to work.Because former brake system does not have
Cancel, for new brake system because of high temperature resistant, the high preferential use of stability has overturned pervious brake mode, to improve guarantee
The reliability of personal safety as well as the property safety.
5, conventional truck descending can not stop working, because needing hydraulic power and braking effort when descending.The present invention is with belt
Wheel connect by belt with hydraulic device, and excess power when vehicle descending drives transmission shaft again with hydrodynamic pressure dress by belt pulley
It sets, direction and brake hydraulic power is provided, so as to the fuel-economizing, emission reduction of stopping working.
