Limitation, it is any to change in the form rather than substance the protection model that all should be considered as the utility model according to the utility model design
It encloses.
Referring to Fig. 1, the utility model relates to a kind of force braking device, including brake shoe 1, scalable bearing bar 2 with
And elevating mechanism.The brake shoe 1 is being intervally distributed with several columns on-slip tooth along braking direction on the bottom surface of ground face contact
11, with the sequencing contacted with road surface, the material of on-slip tooth 11 is gradually rigid steel material by soft wear-resistant material transition
Material, the soft wear-resistant material is preferably rubber for tire, and the rigid steel material is preferably stainless steel.Described stretches
The lower end of bent bearing bar 2 is connect with brake shoe 1, and on braking direction can around with the tie point of brake shoe 1 carry out 90 degree with
Interior rotation.The elevating mechanism and scalable bearing bar 2 are sequentially connected, for realizing scalable bearing bar 2 it is quick under
It puts or is promoted.
Referring to Fig. 2, illustrating the structural schematic diagram of an embodiment of the scalable bearing bar 2, referred to as straight-bar
The scalable bearing bar of formula.In this embodiment, the scalable bearing bar 2 is made of several segments cylinder straight-bar 21, adjacent
It is socketed between two straight-bars 21 by the combination of male and female head and pivot pin (not shown).
Further, the elevating mechanism uses hydraulic jack roof construction, and the hydraulic jack roof construction includes liquid
Cylinder pressure, and add one section of horn-like joining section (not shown) in the opening of hydraulic cylinder, convenient in embodiment illustrated in fig. 2 can
Stretch the ejection and contraction of the cylindrical straight-bar 21 of bent bearing bar 2.
Referring to Fig. 3, illustrating the structural schematic diagram of another embodiment of the scalable bearing bar 2, referred to as chain
The scalable bearing bar of formula.In this embodiment, the scalable bearing bar 2 include several pairs of connection sheets 22, be folded in it is each
To several tooth blocks 23 between connection sheet 22 and for several pivot pins 24 of tooth connection block 23 and connection sheet 22.The tooth block
23 are successively intervally arranged along short transverse, and each tooth block 23 offers from side in centre penetrate through leading to the other side along its length
Hole 231, in connection sheet 22 and the through-hole 231 of corresponding each tooth block 23 offers several connecting holes 221, and the pivot pin 24 is inserted in
In connecting hole 221 and through-hole 231.Spacing size between each tooth block 23 has determined that the maximum of scalable bearing bar 2 stretches bent angle.
The section of one end towards braking direction of tooth block 23 uses rectangle, trapezoidal or inverted trapezoidal, is using trapezoidal or inverted trapezoidal feelings
Under condition, the curvature of scalable bearing bar 2 can be further reduced or be increased, and is then used backwards to the section of one end of braking direction
Triangle.The scalable bearing bar 2 is due to using the structure being made of several segments as shown in Figures 2 and 3, by section

Collective effect under, the C-shaped scalable bearing bar 2 of initial configuration is stretched rapidly by C-shaped as I shape, is drawn wheel and is gradually taken off
From the ground.Then, the scalable bearing bar 2 is further transferred, and is finally pressed into reverse c-shape, and traction wheel completely disengages ground
Thoroughly braking is realized in face.
Hereinafter, the application examples to the utility model is illustrated.Firstly, respectively before and after the automobile immediately ahead of four tires partially
It crosses on the vehicle frame supporting point of a tyre width and the force braking device is installed, wherein the label at automobile left side front-wheel is
Number, label at car right side front-wheel is number, and the label at automobile left side rear-wheel is number, after being located at car right side
Label at wheel is number, and the overall length of the scalable bearing bar 2 in No. 1 and No. 2 will be more than that scalable in No. 3 and No. 4 is held
The overall length certain proportion of weight bar 2.Secondly, pressure sensor is installed additional in the elevating mechanism of the force braking device everywhere,
And it is corresponding with the label of force braking device, it is respectively labeled as No. 1 pressure sensor, No. 2 pressure sensors, No. 3 pressure and passes
Sensor and No. 4 pressure sensors, the pressure data marshalling being subject in four pressure sensors reach pressure management system, organize into groups
The priority of the data processing of formation is " 1,2 ", " 3,4 ", " 1,3 " and " 2,4 ", and pressure management system is according to the big of marshals data
It is small, the instruction for accelerating decentralization is issued to the corresponding elevating mechanism of small pressure.Automobile by force braking device brake when, due to
The overall length of scalable bearing bar 2 in 1, No. 2 force braking device of front-wheel will be more than scalable in 3, No. 4 force braking devices
The overall length certain proportion of bearing bar 2, the height for allowing for vehicle front jack-up in this way is more than the height of rear-wheel jack-up, automobile weight
The heart integrally moves back, and is more advantageous to completion braking.Further, since the lifting auxiliary control of pressure sensor and pressure processor is made
With the lesser force braking device of stress can relatively accelerate lowering velocity, make automobile according to front and back, right left priority
It is able to achieve the braking of s shape route in braking, further shortens the linear distance of braking.
