Abstract
" self-actuated brake " is a kind of brake device for car.Its centre point is the drive plate that is similar to power-transfer clutch by its principle, power is used in the rotation of wheel is used for driving brake component and wheel is braked.It has saved the actuating unit of hydraulic pressure that present drg adopted or vapour pressure, and operates light.The drg that uses on " self-actuated brake " and the present automobile is compared, has the advantage that simple in structure, reliable operation, braking force by force, do not expend the energy, and because this drg can maintain the braking mode to wheel after parking, institute is so that automobile needn't be installed Parking Brake separately.
Description
Invention field: a kind of brake device for car.
Present state of the art: the various automobiles of home and abroad production at present all are to adopt the mode of hydraulic pressure or vapour pressure that the automobile in advancing is braked.Its braking force is to supply with by manpower or driving engine, because of rather than operation require great effort, expend the energy exactly.And these drgs also all must have the transmission device of cover hydraulic pressure or a vapour pressure, and this has not only improved cost, has also increased the own wt of automobile.Particularly for relying on driving engine that the brake system of braking force is provided, the power of consumption of engine not only, and when driving engine is not worked, also will be directed at the danger that loses braking force.The running brake that adopts on the present automobile, because it can not keep the braking mode of automobile after parking, also must after installation one cover supplies to stop in addition on the automobile, make automobile keep the Parking Brake of original position, thereby cause double brake system and dual operation on the present automobile.
Content, purpose and the advantage thereof of invention: " self-actuated brake " of the present invention can overcome the above-mentioned deficiency of present brake system of car, its centre point is to contact with the rotating element of wheel by the drive plate that its principle is similar to power-transfer clutch, be used for driving brake component and power is used in the rotation of wheel, wheel is braked.This drive plate promptly can be directly with contacting of wheel, also can carry out indirectly by other device, its objective is from wheel and obtains power.Drive plate also can be undertaken by variable gear and buffering spring the driving of brake component.This operation of braking means control part is to be made of the mechanism that can transmit operating effort, its feature is that a holding device that can maintain the braking mode of drg is arranged, the effect of this device is when brake pedal is floored, it just tangles automatically and maintains the braking mode of drg, when brake pedal depressed once more, it just unclamped and discharges braking mode.The brake portion of this brake equipment can be drum-type, disc type or other the various component set-ups that can force it to stop operating to the wheel application of force that adopt on the present automobile.
The drg that uses on " self-actuated brake " of the present invention and the present automobile is compared, and can save the power-driven mechanism of hydraulic pressure and vapour pressure, and failure-free braking force source is arranged; Its does not have wheel and is used for Light-duty Vehicle or is used for heavy goods vehicles, and it is light all to have an operation, and braking force is strong, reliable operation and do not expend the characteristics of the energy, and this drg can make automobile that Parking Brake needn't be installed separately.
Implementation example: shown in the drawings is an example of " self-actuated brake " of the present invention.Because its brake component is the drum-type that extensively adopts on the present automobile, event here is not described in detail the function of brake component, here only give more detailed explanation, be to illustrate the principle of work of " self-actuated brake " order with regard to the relevant part of the present invention.
As shown in drawings, it is that the axle center links to each other with wheel disc axle 2 jointly that drive plate 1 also has the upper end of dish axle push rod 4 with brake shoe expander 19, and they can each autorotation.One end of this wheel disc axle is embedded in the U-lag 20 on the back-plate 16, can move up and down along groove, and its other end can have pedestal to support.Have two cams to refute pin 3 on the brake shoe expander 19, their end stretches out respectively in two bending grooves 17 on drive plate, and the spring of groove inside-paint is the signal buffer action, and in fact it is more suitable for being placed on wheel disc axle or the drive plate.For making two brake straps 18 wearing and tearing evenly, the pivot center of brake shoe expander is in its position on the upper side, center.Dish axle push rod 4, dish axle bottom bar 14 are linked by bearing pin 5 jointly with control pull rod 6, and can relatively rotate.There is a lead screw 13 that is used for the adjusting yoke stroke termination of control pull rod, and by being fixed on that reset tension spring 11 on the pin 12 is held and the release position that keep drg.A hook box 7 that is fixed on the back-plate 16 is equipped with at the middle part of control pull rod 6, when pull bar moves in this box, can be tangled and decontrol, in order to the braking mode that keeps and release the brake.Operation pull bar 8 with refute bar 9 and linking by the both sides of bearing pin 10 from back-plate, this pull bar and the angle of refuting between the bar can be fixed after regulating, and are the axle center co-rotation with bearing pin 10.Refute the termination that bar can confutation control pull rod 6 and drive its motion.
Working process: when operation pull bar 8 is subjected to power that brake pedal transmits and during to arrow direction, the refute bar 9 coaxial with it just drives control pull rod 6 to equidirectional motion, thereby makes drive plate be subjected to the bearing force upward movement of the pivot pin 15 on the back-plate and form inscribe with brake wheel and contact.At this moment Xuan Zhuan brake wheel is just given equidirectional turning effort of drive plate.The rotation of drive plate drives that brake shoe expander 19 rotates and squeezes to both sides and to open brake shoe brake cheek 18, makes it compress brake wheel and brake wheel.When loosen the brake, the drive plate disengaging discharges braking mode with contacting of brake wheel.When brake pedal depressed certain stroke, hook box 7 maintained braking mode, at this moment, no matter whether unclamp pedal, the braking mode of drg can not be released, and has only when brake pedal is depressed same position once more, hook just can unclamp, and discharges braking mode.
