The rotatingshaft of wheel 7 is exactly target rotatingshaft 10, is connected with bent axle 9, and bent axle 9 is directly connected with piston 6 again, and therefore the rotation of wheel 7 directly drives piston 6 to-and-fro motion, so just can control the rotation of wheel 7 by direct control piston 6 motions.The to-and-fro motion of piston 6 drives the gas inlet and outlet in cylinder body 5, and it is to encircle gas inlet and outlet that cylinder body 5 only has a mouth, and the opening and closing state of this mouthful has fluid switch 2 directly to control.The free air inlet of piston 6 and exhaust in the time that fluid switch 2 is opened, when air inlet, because the interior pressure of cylinder body 5 is lower than the external world, the elastic baffle 3 on suction port 4 is opened by barometric pressure, and gas enters cylinder body 5 by fluid switch; When exhaust, because the interior pressure of cylinder body 5 is greater than external atmosphere pressure, elastic baffle 3 is closed, and gas is pressed into gas tank 11, stores for other assembly.In the time that fluid switch 2 is closed, piston 6 can not free air inlet and exhaust, and the motion of piston 6 is prevented from, and wheel 7 has been played to braking action.The movable fixed end 16 of cylinder body is connected with car body, fixes with pin, and therefore cylinder body 5 and piston 6 can swing back and forth with bent axle 9.
The gas that gas tank 11 stores can use for other assembly, and these gases can pass through motor 12 by pipeline, take away the heat of motor 12, heats, and can control by pipe switch 1 when being transported to the inherent cold of car.These gases can also enter air cooler by pipeline, and the evaporation plate 15 of air cooler provides water by water tank 8, and when the moisture evaporation of gas in out-of-date quickening evaporation plate 15, absorption refrigeration, plays refrigeration when these cold air are transported to the inherent sweltering heat of car.
In Fig. 2,1 fluid box, 2 liquid entering holes, 3 fluid flow ports, 4 fluid passages.
When hydrokinetic brake is with liquid during as working medium, just can not provide pressurized gas for other assembly, but braking ability improve greatly.Liquid used is oil but in particular cases can makes water, but all piston is played to lubrication, can increase the life-span with oil.The liquid using is added fluid box 1 by liquid entering hole 2, and fluid box 1 is connected with fluid flow port 3 by fluid passage 4, and the turnover liquid of fluid flow port 3 is by fluid switch control.Optimal liquid amount state when piston movement is full of by liquid in cylinder body when to lower end.

In Fig. 6,1 fluid inlet, 2 target rotatingshafts, 3 fixed terminals, 4 slide plates, 5 fluid outputs, 6 row's fluid switchs, 7 communication of fluid passages
Cross axle sliding vane break, because slide plate 4 is through the central shaft of target rotatingshaft 2, target rotatingshaft 2 is tangent with brake casing inwall, and slide plate 4 two ends contact with brake casing inwall all the time, is not circle and oval so slide plate only has the track that and slide plate two ends slip over.So the shape of this brake casing inwall need to be by calculating, if (2) in figure are taking the center of target rotatingshaft as initial point is set up rectangular coordinate system, the track just in time slide plate two ends being slipped over is divided into four sections, one section, each quadrant and X-axis above two sections and X-axis once two sections be respectively about Y-axis mirror image symmetry, as long as determine the position of the interior any one section of track of four quadrants and slide plate 4 length and target rotatingshaft 2, just can determine the shape of whole brake casing inwall.
Target rotatingshaft 2 rotates and drives slide plate inspiration and discharge fluid.The rotary state of target rotatingshaft 2 is also being controlled in the discharge that row's fluid switch 6 is controlled fluid simultaneously.Fixed terminal 3 is used for fixing break.
(2) be axle sliding vane break enlarged view.
(3) be that break uses liquid during as working medium, the diagram that fluid inlet 1 is connected by communication of fluid passage 7 with fluid output 5.
Fig. 7 is the control of sliding vane break two-fluid switch
Sliding vane break has fluid inlet and fluid output, installs respectively into fluid switch and row's fluid switch, and each switch can be controlled separately the rotation situation of target rotatingshaft, can brake.When sliding vane break is braked with single fluid switch control, break is all half of stressed, one side of something is just likely reduced by the stability of dynamic braking, in order to make break stressed evenly, adopt two-fluid switch to control braking simultaneously, enter fluid switch and the synchronous braking of row's fluid switch, make brake compensation as far as possible.Simultaneously due to break stressed evenly and also making a concerted effort of being subject to for original two times, strengthened braking ability.
Reciprocating piston type break only has a fluid flow port, makes brake compensation adopt symmetrical piston structure.
When the braking of sliding vane break employing gas working medium, fluid row mouth can be connected to storage gas with gas tank and encircle other assembly use, can cooling and heating.When sliding vane break adopts liquid working substance braking, the speed of response of braking is very fast, faster than frictin braek, and braking ability is also good especially.Sliding vane break needs liquid feeding while using liquid working substance, in the time that interpolation liquid flooded communication of fluid passage completely, be best liquid volume added.
When hydrokinetic brake uses gas working medium braking, can produce pressurized gas storage, supply with other Pneumatic assembly and use, can also cooling and heating.Use liquid working substance when braking, need to add worker quality liquid, braking response and performance are better than gas working medium, and worker quality liquid is when not enough or while having lighter leakage, can not brake complete malfunctioning situation.Biswitch control or symmetrical piston structure provide double brake ability for break, if break is while having influent stream body or the impaired generation of row's fluid section to leak, leak fluid position is no more than an overall half break and still can brakes.And can add water can not add worker quality liquid in time under special circumstances time and do worker quality liquid.
