Description
Technical field
This utility model belongs to brake device for car technical field.
Background technology
At present in China or even other countries of the world, all kinds of lorries the vehicle accident directly resulted in takes place frequently, and causes serious people
Body injury and economic loss.In the range of China, the vehicle accident accounting about 40% that lorry causes, death toll accounting more than 70%,
Become maximum traffic safety hidden danger.It is brake failure that lorry becomes the reason of " maximum road killer ", and especially overload bulk production
The accident that car brake failure causes is the most frequent.Brake failure has become as the technical factor that truck generation vehicle accident is the most fatal.
Existing truck brake system is mainly made up of parts such as power supply device, control device, actuating device and brakes, passes through
Brake train and make wheel stop the rotation.But due to a variety of causes, brake failure usually occurs, or because of master cylinder
In impurity is too many, poorly sealed, vacuum booster pump lost efficacy, brake fluid is the dirtiest, brake pump leakage of oil, air accumulator or pipe interface leakage
Gas, or owing to long-time descending makes brake block frictional heat, brake block and wheel hub high temperature cause brake block Organic substance to melt out friction
Coefficient reduces, brake function lost efficacy, or owing to serious overload increases vehicle motional inertia, directly results in brake failure.
In view of above-mentioned present situation, applicant arranges and has made a kind of truck spare emergent brake, and number of patent application is
201510990623.2, mainly a set of piston mechanism and drag link mechanism are installed on card crossbeam, at piston mechanism and draw-bar machine
Structure lower end is installed, frictional damping plate, and when vehicle brake is malfunctioning, frictional damping plate can fall to contact with ground, produces and strongly rubs
Wipe, play the effect of brake, thus the danger occurred when stoping car braking malfunctioning.But this device technique structure is the most multiple
Miscellaneous, cost is higher, and maintenance cost is the highest, causes some car owners to be unwilling to install and use.
Summary of the invention
The purpose of this utility model is the deficiency in order to solve to be limited to technology, it is provided that a kind of structure is simpler, manufacture and safeguard into
There is danger time malfunctioning in this lower existing freight car braking of prevention, it is provided that a kind of plain type truck emergency brake device.
The purpose of this utility model is achieved through the following technical solutions:
A kind of plain type truck emergency brake device, includes the draw-bar seat being installed on card crossbeam and is positioned at draw-bar seat rear
Tip-lever support, scalable or that rotate suspension bayonet lock, the upper end being installed between draw-bar seat and tip-lever support are pacified by bolt or bearing pin
The push rod that the two connecting rod pull bars that are loaded in draw-bar seat, upper end are installed in tip-lever support by bolt or bearing pin, two connecting rod pull bar and tops
The lower end of bar all connects frictional damping plate by bolt or bearing pin.
On suspension bayonet lock described in the utility model equipped with drive hang bayonet lock flexible or rotate pneumatically or electrically or hydraulic-driven dress
Putting, this is pneumatically or electrically or fluid pressure drive device electrically connects with the activate switch being arranged at driver's cabin.This utility model is symmetrically installed
On two crossbeams of truck.
This utility model is installed on card crossbeam rear portion, the when of use, two connecting rod pull bars is hung on suspension bayonet lock, this
Time, two connecting rod pull bars and push rod become cantilever, are mentioned by frictional damping plate and be in suspension status.When truck brake is malfunctioning, department
Machine, in driver's cabin activate switch, utilizes pneumatic or electronic or fluid pressure drive device make suspension bayonet lock retraction or rotate, and two even
Bar pull bar, push rod and frictional damping plate rely on own wt to fall, and frictional damping plate contacts with road surface and produces friction, at truck
Under effect of inertia forward, push rod and frictional damping plate can be by truck slightly jack-up, and two connecting rod pull bars are straightened simultaneously, top, location
In vertical state, whole brake unit layout triangular in shape, structure is the most firm for bar.Now vehicle rear weight is pressed in friction system
On dynamic plate, produce huge frictional force, it is achieved braking purpose.
This utility model is simple and reliable for structure, and manufacturing cost and maintenance cost are the most relatively low, it is easy to popularization and application.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that this utility model is installed on card crossbeam rear portion；
Fig. 2 is schematic diagram during braking；
Fig. 3 is the A direction view that in Fig. 2, this utility model is installed；
Fig. 4 is the B direction view that in Fig. 2, this utility model is installed.
Detailed description of the invention
A kind of plain type truck emergency brake device as shown in Figure 1 to 4, includes after being installed on and being positioned on card crossbeam 10
Take turns draw-bar seat 1 and the tip-lever support 2 at draw-bar seat rear of 11 rear positions, be installed between draw-bar seat 1 and tip-lever support 2
Scalable or rotate hang bayonet lock 3, two connecting rods that upper end is installed in draw-bar seat by the first bolt or the first bearing pin 7 draw
The push rod 5 that bar 4, upper end are installed in tip-lever support by the second bolt or the second bearing pin 8, two connecting rod pull bars 4 and push rod 5 times
End all connects frictional damping plate 6 by the 3rd bolt or the 3rd bearing pin 9, and length L of the epimere bar of two connecting rod pull bars is equal to pull bar
Seat and the distance hung between bayonet lock.Equipped with driving suspension bayonet lock flexible or rotating pneumatically or electrically on described suspension bayonet lock 3
Or fluid pressure drive device, this pneumatically or electrically driving means electrically connect with the activate switch being arranged at driver's cabin.This utility model
Device is symmetrically arranged on the crossbeam of truck both sides.
Two set this utility model are symmetrically arranged on the rear portion being positioned at truck rear wheel on the crossbeam of truck both sides, the when of use, will
Two connecting rod pull bars hang on suspension bayonet lock, and now, the epimere bar of two connecting rod pull bars is the level of state, and hypomere bar is overhang,
Hypomere bar and the push rod of two connecting rod pull bars become cantilever, are mentioned by frictional damping plate and are in suspension status.When truck brake is malfunctioning,
Driver, in driver's cabin activate switch, utilizes pneumatic or Vidacare corp to make suspension bayonet lock bounce back, two connecting rod pull bars, push rod and
Frictional damping plate relies on own wt to fall, and frictional damping plate contacts with road surface and produces friction, it is achieved braking.
