Abstract

The utility model relates to a novel brake arranged on motor vehicles, which is especially suitable for bottom beam vehicles of small passenger vehicles, cars, miniature cars, etc. The utility model can reduce the continuous acting force from a driver to a pedal. By using the self weight of the motor vehicle and the pressure added on the motor vehicle, the utility model increases the friction between ground and the motor vehicle, and shortens the continuous braking distance and the continuous braking time of the motor vehicle. The utility model is composed of an operating handle, a bearing frame with good structure, a bearing frame, a brake cylinder, a touchdown friction pad, etc. When the motor vehicle travels in high speed and meets unexpected risk, the brake pedal is violently trodden, the tires of the motor vehicle roll on the touchdown friction pad, and the motor vehicle quickly stops traveling.

Description

The self-propelled vehicle drg that efficiently lands

The present invention is a kind of New Brake that is applicable to the running on expressway self-propelled vehicle, this drg can with the original drg mating reaction of self-propelled vehicle, be specially adapted to minibus, small passenger car, minicar, wait the bottom girder car to use, the braking effect that is risen is promptly good.

The drg that uses on the present self-propelled vehicle, hydraulic brake is arranged, three kinds of air-pressure brake and hand brakes, these three kinds of drgs are in the emergency braking process, can not reduce self-propelled vehicle inertia forward rapidly, also each parts of self-propelled vehicle machine be had than macrolesion, and, run at high speed the lasting stopping distance of self-propelled vehicle is increased, because the lasting stopping distance of self-propelled vehicle becomes quadratic relationship to increase with the speed of a motor vehicle, when the speed of a motor vehicle is increased to 80 kilometers/hour by 40 kilometers/hour, continue the distance of braking.Will be increased to 4 times of the original speed of a motor vehicle.Simultaneously, time of driver's reaction distance and the drg also corresponding prolongation of operating range of working.

This drg that efficiently lands of the present invention can alleviate the continuous action power of chaufeur to pedal, can utilize the weight of self-propelled vehicle self, increase the brake efficiency of car load, reduce rapidly motor-driven when emergency braking forward inertia, shorten self-propelled vehicle and continue stopping distance, shorten and continue braking time.

The drg that efficiently lands of the present invention is that following mode is finished.

Bar handle is by the AB groove of self-propelled vehicle base plate, stretch in the operator's compartment, the lower end of bar handle has push rod to stretch in the wheel cylinder, plug in the wheel cylinder can be blocked under the effect of pull back spring, put logical, and braking liquid between the master brake cylinder, the other end of brake cylinder connect the drg that efficiently lands the dyanainic friction pad.When self-propelled vehicle drives at moderate speed on highway, bar handle is placed on the bottom plate groove A position, because the effect of pull back spring, the plug in brake cylinder has been blocked the oil pipe passage that connects the drg that efficiently lands, oil pressure in the master brake cylinder like this, just pass less than in the brake cylinder, when self-propelled vehicle need slow down, chaufeur was gently stepped on motor brake treadle, the original drg of self-propelled vehicle plays brake action, and vehicle running speed slows down.As figure (1).When self-propelled vehicle is run at high speed, bar handle is put into the B end by base plate A end, and like this, the oil duct of brake cylinder and master brake cylinder is identical, when chaufeur runs into not calculable danger suddenly, suddenly step on brake pedal, the oil pressure in the master brake cylinder is through oil channel, wheel cylinder, promoting push rod stretches downwards, the rubbing cushion that lands of drg of efficiently landing lands rapidly, and automobile tyre rolls on the rubbing cushion that lands, and the drg that efficiently lands plays brake action.As figure (2).Here the said rubbing cushion that lands, inside is made up of steel wire or nylon wire, and bag one deck is covered with rubber in the outside, is made of one, and the one side of kiss the earth with the antifriction rubber thickening, is made the tire tread shape, increases and ground-surface friction.

When automobile tyre rolls on when landing rubbing cushion, because self-propelled vehicle self is to rubbing cushion pressure and the tire friction to the rubbing cushion that lands that lands, land rubbing cushion and ground will produce a friction, this friction that produces, to be converted into along the pulling force of rubbing cushion that land to the self-propelled vehicle back lower place, begin the size of this pulling force, the friction that rubbing cushion and ground produces equals to land, the formation of this pulling force, pind down self-propelled vehicle a part of inertia forward, also be converted into and strengthen self-propelled vehicle ground-surface pressure, self-propelled vehicle strengthens ground-surface pressure, has also just strengthened land rubbing cushion and ground-surface friction and the pulling force of rubbing cushion to self-propelled vehicle that land, the increasing of friction and pulling force rapidly, to pin down self-propelled vehicle inertia forward again, strengthen self-propelled vehicle again ground-surface pressure ...Up to inertia force of motor vehicles go on foot entirely rapidly offset by friction till.(it is out of service to self-propelled vehicle that automobile tyre rolls on the rubbing cushion that lands, the switching process of this power is to finish in the short time in sight), after self-propelled vehicle is finished brake, loosen the brake, the self-propelled vehicle rubbing cushion that falls down to land backward, the drg reinstatement because the effect of pull back spring efficiently lands is as figure (1).

Also can understand like this: it is long to use former drg to continue stopping distance when why running at high speed? it is short to use the drg that efficiently lands to continue stopping distance when why running at high speed? this is because self-propelled vehicle when running at high speed, self-propelled vehicle is very little to ground-surface pressure, friction is also very little, be directly proportional between pressure and the friction, after the self-propelled vehicle braking, self-propelled vehicle is strengthened by little gradually to ground-surface pressure, uses the lasting stopping distance of former drg long so self-propelled vehicle is run at high speed.And the drg that efficiently lands is to have strengthened self-propelled vehicle rapidly to ground-surface pressure, just strengthens self-propelled vehicle and ground-surface friction rapidly, so self-propelled vehicle continues the stopping distance weak point, is stopped purpose rapidly.

The drg that efficiently lands of the present invention can alleviate the continuous action power of chaufeur to pedal, in addition, the rubbing cushion that lands utilizes the weight of self-propelled vehicle self and the pressure of increasing, self-propelled vehicle and ground-surface friction have been increased, increase the brake efficiency of car load, reduced self-propelled vehicle forward inertia when the emergency braking rapidly, shorten self-propelled vehicle and continued stopping distance and lasting braking time, and this brake structural is simple, and is cheap, easy to use, do not influence outward appearance U.S. of self-propelled vehicle, do not influence motor-driven vehicle going, to the not damage of each parts of vehicle machine, be desirable drg after the reversing, emergency braking at the up motivation motor-car of express highway.
