The utility model has the advantages of novel design reasonable structure, convenient installation, convenient operation, no increase of cost and favorable performance of emergency brake; the utility model can be continuously and repeatedly used for a plurality of times.
Description
The utility model relates to a kind of brake of motor-driven vehicle device, especially a kind of device of making the emergency brake function when being used in the running brake system failure.
Automobile causes the especially big traffic accident of overturning taking place incessantly because of service braking system is malfunctioning, its cross-up causes the pernicious consequence of car crash to cause great threat for the country and people's lives and properties, has been instant thing so on automobile emergency brake is installed.And existing several emergency brake, exist some not enough aspect separately, as a kind of self-locking device, at the car engine machine without power or when flame-out midway, brake pressure just can be automatically with wheel " locking " less than rated pressure, though this mode has been braked automobile, where bad car is, must where repair, be difficult for dragging away; The twin-tube circuit device when it lost efficacy when major loop, utilizes another loop to obtain less braking force, can not set up under the situation of pressure when driving engine, and the pressure of its major minor loop all equals zero, and the less braking force of subloop has not just existed yet; Also has a kind of energy storage type spring brake in addition, also be need be after former service braking system is obtained certain energy storage, Deng service braking system when malfunctioning, energy stored discharged brake, thereby under the situation that the driving brake system pressure can not set up, accumulator just can't store required braking energy.So above-mentioned several emergency brakes also can't use on automobile at present.
The purpose of this utility model is to overcome the problem of prior art existence and a kind of car emergency brake gear is provided, and can make automobile deceleration emergency when former service brake is malfunctioning effectively, avoids automobile because of the contingency that causes out of control.
The purpose of this utility model is achieved through the following technical solutions: a kind of car emergency brake gear, it is characterized in that comprising the non-return anti-obforms hand lever of driving on the indoor floor by being located at, beneath brake oil pump, connect the control link of hand lever and brake oil pump and be located at the brake oil cylinder of brake chassis and T iron hinged place, retracing spring, the oil pipe that connects brake oil pump and brake oil cylinder constitutes, and its brake oil cylinder is by cylinder housing, shell inner carrier body, piston nut outside shelves head, the cylindrical bolt and the seal ring of the band hinged groove in the piston body consist of the limiting header straight type oil cylinder.Its principle of work is as follows: when the driver finds that service brake is malfunctioning, can stretch out one's hand pull-up emergency brake hand lever, pull bar pulling bar linkage structure, application force amplifies, and promotes fuel pump push rod, hydraulic oil adds through oil pipe and is pressed in trailing wheel emergency brake oil cylinder, the hydraulic drive piston body is outwards made bidirectional-movement in the oil cylinder, promotes both sides T iron expansion, the mutual fricative friction force of T iron facies palmaris friction lining and brake hubs, make wheel decelerates, stop, reach the purpose of emergency brake.
The utility model modern design, rational in infrastructure, easy for installation, processing ease, emergency brake performance are good, but the continuity repeated multiple times use, do not absorb the energy of driving engine and storage battery, can not increase expensively, have practical value.
Below in conjunction with accompanying drawing in detail the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is embodiment 1 scheme drawing of the present utility model.
Fig. 3 is embodiment 2 scheme drawings of the present utility model.
Fig. 4 is a brake oil cylinder scheme drawing of the present utility model.
As Figure 1-3, a kind of car emergency brake gear, comprise by be located at the non-return anti-obforms hand lever (22) driven on the indoor floor, beneath brake oil pump (20), connect the control link (21) of hand lever (22) and brake oil pump (20) and be located at brake chassis and T iron (1) hinged place brake oil cylinder (2), retracing spring (4), is connected oil pipe (13) formation of brake oil pump (20) and brake oil cylinder (2).As shown in Figure 4, brake oil cylinder (2) comprises by the stop nut shelves head (9) in cylinder housing (15), shell inner carrier body (16), the piston outside, piston body (16) and consists of limiting header straight type oil cylinder with the seal ring (12) that the cylindrical bolt (11) and the liner of negative thread connecting band hinged groove (10) stops hydraulic pressure to stagnate outward, regulate the flexible of inner bolt (11) by shelves head (9) rotation, be used to regulate the braking gap between bremsbelage (23) and the brake hubs (7).This device only is applicable to makes the automobile back wheel emergency brake, the braking procedure of its rear wheel brake device is as follows: when automobile is implemented service brake, driver's pin is stepped on brake pedal (17), promote brake oil pump (18) or open the gas switch of stopping by connecting rod (19), as Fig. 2, shown in 3, power transmission to service brake oil cylinder (3) piston of oil brake stretches out, or the cam of pneumatic brake is chosen iron (8) rotation, promoting T iron (1) expands outwardly, the other termination of two T iron (1) and emergency brake oil cylinder (2) two ends pistons (16) are hinged, its hinge-point becomes the fulcrum of T iron (1) motion under retracing spring (4) effect.Because oil brake brake cylinder (3) piston stretches out or iron (8) rotation is chosen in pneumatic brake, promote the power that T iron (1) expands outwardly, major part is converted into drag friction power, along T iron (1) gusset to the counterparty to extension, the surplus energy that acts on the hinge-point of emergency brake oil cylinder (2) piston (16) two ends is very little, because of brake oil cylinder (2) is spacing shelves hair style, surplus energy is eliminated on the contact surface of piston limiting header (9) and cylinder body (15), avoided the stressed impact of fulcrum to oil cylinder piston (16), more safe and reliable.Oil brake is when using emergency brake, and the hinge-point of service brake oil cylinder (3) piston two ends and T iron (1) termination under retracing spring (5) effect, becomes the fulcrum of T iron (1) motion; Or pneumatic brake is when using emergency brake, and emergency brake oil cylinder (2) piston promotes T iron (1) and expands outwardly, and chooses the contact surface of iron (8) and T iron (1) termination, under the effect of retracing spring (5), becomes the moving fulcrum of T Railway transportation.The service brake oil cylinder (3) of oil brake rear wheel brake device is relative with emergency brake oil cylinder (2) position, and structure is identical, each other fulcrum.In addition, during brake T iron (1) extensional motion, the buffer-type fastener (6) that connects T iron and the effect of fixing of brake chassis with T iron (1) gusset middle part is rotating shaft, the arc fricting movement that work expands outwardly, guaranteed moving stability, naturality, regularity and the safety of T Railway transportation, also guaranteed the reliability of car emergency brake actuating mechanism, service brake and two kinds of functions of emergency brake have been realized on the rear wheel brake device, finishing, do not disturb the feasibility that is independent of each other, reliability and integraty again mutually.
