具体实施方式
以下结合附图，对本发明作进一步说明：
如图1所示，图1是货车鼓式刹车散热系统的剖面结构示意图，该货车鼓式刹车散热系统包括刹车鼓3、刹车蹄6和刹车片4，刹车鼓3内有一对弧形的刹车蹄6，在刹车鼓3的内壁上设有若干个刹车鼓铆钉孔，刹车片4上设有与刹车鼓铆钉孔对应的刹车片铆钉孔，上述刹车片4通过铆钉固定在刹车鼓3的内壁上；如此一来，将现在普遍采用的货车刹车时，刹车片4与刹车鼓3摩擦产生制动效果，改造成为刹车片4与刹车蹄6摩擦产生制动效果，产生的热量大多集中在刹车蹄6上。
将刹车蹄内腔9掏空，刹车蹄6相对的其中一端用导管7相连，相对的另一端，一块刹车蹄6设有刹车蹄进水管1，另一块刹车蹄6设有刹车蹄出水管2，由于热量大多集中在刹车蹄6上，而刹车蹄内腔9掏空了，即可通过采用内循环冷却的方式对刹车蹄6进行散热，所以，在刹车蹄进水管1和刹车蹄出水管2之间设有水箱循环散热装置或带有水泵29和散热器21的机械循环散热装置，使水循环通过2块刹车蹄6，即可降低刹车蹄6的温度。
为防止水从轮胎渗入刹车鼓3中，在刹车鼓3外侧设有刹车鼓罩8。
以下列举4种具体内循环冷却刹车蹄6的实施例：
实施例1
图3是本实施例中水箱循环散热装置的结构示意图，如图3所示，水箱循环散热装置包括水箱17、水箱进水管18和水箱出水管19，水箱17设在货车高于大梁的位置，水箱17的底部设有水箱进水管18和水箱出水管19；水箱进水管18与刹车蹄出水管2相连，水箱出水管19与刹车蹄进水管1相连。
当驾驶员踩刹车时，刹车蹄6与刹车鼓3内壁上的刹车片4接触摩擦，摩擦产生的热能使刹车蹄内腔9中的水温度升高，温度升高的水变成蒸汽再从刹车蹄出水管2和水箱进水管18流到水箱后，经水箱17中的水冷却，再从水箱出水管19流出，蒸发掉的水由刹车蹄进水管1流入刹车蹄内腔9中进行补充。
实施例2
如图4所示，图4是本实施例中机械循环散热装置的结构示意图，该机械循环散热装置包括发电机27、电缆28、电机22、高压管30、回流管20以及相连的水泵29和散热器21，发电机27是由货车的传动轴23通过分合器24和输出传动轴26带动其运转，发电机27的输出端通过电缆28与电机22相连，电机22的一端与水泵29和散热器21的风叶相连，从而驱动相连的水泵29和散热器21，水泵29的另一端与高压管30的一端相连，高压管30的另一端与刹车蹄进水管1相连，散热器21的另一端与回流管20的一端相连，回流管20的另一端与刹车蹄出水管2相连；
为使发电机可以合理利用传动轴23的动力，变速箱25尾端与传动轴 23相连，设置传动轴23与分合器24的一端相连，分合器24的另一端与输出传动轴26的一端连接，输出传动轴26的另一端与发电机27连接，设置货车刹车时分合器24把传动轴23与输出传动轴26连接起来，使得传动轴23带动输出传动轴26转动，从而带动发电机27运转。
当驾驶员踩刹车时，即触动分合器24把传动轴23与输出传动轴26连接，动力轮转动带动传动轴23转动，输出传动轴26也随之转动，进而带动发电机27转动发电，发出的电经电缆28流到电机22，电机22再驱动水泵29和散热器21内的风叶转动，水泵29转动使从散热器21流进的水压力增大(这里所说的水是加了防冻剂的水)，再从高压管30流到刹车蹄进水管1，流过经导管7连接的刹车蹄内腔9，之后再从刹车蹄出水管2流到回流管20再流到散热器21里，刹车蹄6与刹车片4摩擦产生的热量被刹车蹄内腔9的水吸走再经散热器21之后，热量就被散热器21吸收散发到空气中去，被吸收掉热量的水再流进水泵29，如此循环，该系统不耗费发动机一丝功率，完全依靠踩刹车时货车的惯性带动输出传动轴26转动转换成能量来完成。当驾驶员松开刹车时，分合器24使传动轴23与输出传动轴26断开，该系统立即停止运行。
实施例3
如图5所示，图5是本实施例中机械循环散热装置的结构示意图，该机械循环散热装置包括高压管30、回流管20以及相连的水泵29和散热器21，水泵29和散热器21由货车的传动轴23通过分合器24和输出传动轴26带动运转，水泵29的一端与高压管30的一端相连，高压管30的另一端与刹车蹄进水管1相连，散热器21的一端与回流管20的一端相连，回流 管20的另一端与刹车蹄出水管2相连。
为合理利用传动轴23的动力，变速箱25尾端与传动轴23相连，设置传动轴23与分合器24的一端相连，分合器24的另一端与输出传动轴26的一端连接，输出传动轴26的另一端与水泵29和散热器21的风叶连接，设置货车刹车时分合器24把传动轴23与输出传动轴26连接起来，使得传动轴23带动输出传动轴26转动，从而带动水泵29和散热器21运转。
当驾驶员踩刹车时，即触动分合器24把传动轴23与输出传动轴26连接，动力轮转动带动传动轴23转动，输出传动轴26也随之转动，输出传动轴进而带动水泵29和散热器21内的风叶转动，水泵29将从散热器21流进的水加压后(这里所说的水是加了防冻剂的水)，再从高压管30流到刹车蹄进水管1，流过经导管7连接的刹车蹄内腔9，之后再从刹车蹄出水管2流到回流管20再流到散热器21里，刹车蹄6与刹车片4接触摩擦产生的热量被从刹车蹄进水管1流进来的水带走，从刹车蹄出水管2经回流管20流入散热器21中，散热器21的风叶转动带动空气从散热器21内的散热片经过，进而吸走流经散热片21内的水的热量，使其热量散发到空气中。被散发掉热量的水再流入水泵29中进行加压。如此循环可使刹车摩擦产生的热量及时散发的空气中去，确保行车安全。该系统不耗费发动机一丝功率，完全依靠刹车时产生的惯性带动输出传动轴23转动转换成能量来完成的，当松开刹车后分合器24将大传动轴与输出传动轴断开，该系统立即停止运行。
实施例4
如图6所示，图6是本实施例中机械循环散热装置的结构示意图，该 机械循环散热装置包括液压油泵33、进油管34、回油管32、液压旋转器31、高压管30、回流管20以及相连的水泵29和散热器21，液压油泵33由货车的传动轴23通过分合器24和输出传动轴26带动，液压油泵33的进油管34和回油管32分别与液压旋转器31连接，液压旋转器31驱动相连的水泵29和散热器21，水泵29的一端与高压管30的一端相连，高压管30的另一端与刹车蹄进水管1相连，散热器21的一端与回流管20的一端相连，回流管20的另一端与刹车蹄出水管2相连；
为合理利用传动轴23的动力，变速箱25尾端与传动轴23相连，设置传动轴23与分合器24的一端相连，分合器24的另一端与输出传动轴26的一端连接，输出传动轴26的另一端与液压油泵33连接，设置货车刹车时分合器24把传动轴23与输出传动轴26连接起来，使得传动轴23带动输出传动轴26转动，从而带动液压油泵33运转。
当驾驶员踩刹车时，即触动分合器24把传动轴23与输出传动轴26连接，动力轮转动带动传动轴23转动，输出传动轴26也随之转动，输出传动轴26带动液压油泵33转动，液压油泵33转动产生高压液压油经进油管34流入液压油旋转器31从而推动其旋转，最后再从回油管32流入液压油泵33，液压油旋转器31转动带动水泵29和散热器21内的风叶转动。水从散热器21流入水泵29(这里所说的水是指加了防冻剂的水)，水泵29将其加压后经高压管30从刹车蹄进水管1流入刹车蹄内腔9中，之后再从刹车蹄出水管2经回流管20流入散热器21内。刹车蹄6与刹车片4摩擦产生的热量被从刹车蹄进水管1流入刹车蹄内腔9的水带走再从回流管20流入散热器21内，风叶转动使散热器21将流入的水的热量吸走并将其散发 到空气中去，被吸收掉热量的水再流到水泵29中重新加压，如此循环，将刹车蹄6与刹车片4摩擦产生的热量散发到空气中去。该系统不耗费发动机一丝功率，完全依靠惯性带动输出传动轴转动转换成能量来完成的，当松开刹车后，分合器24将传动轴23与输出传动轴26断开，该系统立即停止运行。
由于货车往往有多个桥，每个桥都有两个刹车鼓3，每个刹车鼓3内的刹车蹄6都装有刹车蹄进水管1和刹车蹄出水管2，在多个刹车鼓3的刹车蹄进水管1和刹车蹄出水管2在和高压管30和回流管20连接时以并联的方式连接，这样更能及时高效地进行散热；如果是牵引车与挂车时，可将分合器24、输出传动轴26、水泵29、散热器21等安装在牵引车上，再将挂车上已并联好的高压管30和回流管20拉到挂车与牵引车交接最近的地方，并且高压管30和回流20管各有一开关。牵引车上的高压管30和回流管20的末端有一开关，该开关与挂车上的高压管30和回流管20上的开关可自由对接。当牵引车与挂车分开时将这开关拆开即可，当牵引车与挂车合拢时，将这两开关对接即可，这样可使挂车能有与牵引车同样的刹车散热效果。
如图2所示，图2是货车蝶式刹车散热系统的剖面结构示意图，该货车蝶式刹车散热系统包括刹车盘15、活塞10和盘形刹车片16，刹车盘15两外侧有一对活塞10，刹车盘15上设有若干个刹车盘铆钉孔，盘形刹车片16上设有与刹车盘铆钉孔对应的刹车片铆钉孔，盘形刹车片16通过铆钉5固定在刹车盘15的外壁两侧上；盘形刹车片16设计为圆盘形，可覆盖在刹车盘15外侧，能保证刹车时盘形刹车片16都可与活塞10产生摩擦，如 此一来，将现在普遍采用的货车刹车时，刹车片与刹车盘15摩擦产生制动效果，改造成为盘形刹车片4与活塞10摩擦产生制动效果，产生的热量大多集中在活塞10上。
将活塞内腔13掏空，活塞10相邻的其中一端用导管7相连，相邻的另一端，一块活塞10设有活塞进水管11，另一块设有活塞出水管12；由于热量大多集中在活塞10上，而活塞内腔13掏空了，即可通过采用内循环冷却的方式对活塞10进行散热，所以，在活塞进水管11和活塞出水管12之间设有水箱循环散热装置或带有水泵29和散热器21的机械循环散热装置，使水循环通过导管7相连的两块活塞10，即可降低活塞10的温度。
在活塞10外侧设有活塞外壳14，用于支撑活塞10。
以下列举4种具体内循环冷却活塞10的实施例：
实施例5
图3是本实施例中水箱循环散热装置的结构示意图，如图3所示，水箱循环散热装置包括水箱17、水箱进水管18和水箱出水管19，水箱17设在货车高于大梁的位置，水箱17的底部设有水箱进水管18和水箱出水管19；水箱进水管18与活塞出水管12相连，水箱出水管19与活塞进水管11相连。
当驾驶员踩刹车时，活塞10与刹车盘15两外侧上的盘形刹车片16接触摩擦，摩擦产生的热能使活塞内腔13中的水温度升高，温度升高的水变成蒸汽再从活塞出水管12和水箱进水管18流到水箱17后，经水箱17中的水冷却，再从水箱出水管19流出，蒸发掉的水由活塞进水管11流入活塞内腔13中进行补充。
