Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.Herein it should be noted that
It is used to help understand the utility model for the explanation of these embodiments, but does not form to restriction of the present utility model.This
Outside, as long as technical characteristic involved in each embodiment of the utility model disclosed below does not form conflict each other
Can is mutually combined.
A kind of drum reaction type vehicle loading brake test bench disclosed in the utility model, its principle is as shown in Fig. 2 allow
One axle wheel 13 and three axle wheels 15 make the gravity of detected two-axle car wheel 14 act on braking inspection completely slightly off ground
On the viscous husky roller 6 of scaffold tower, the adhesive force between increase two-axle car wheel 14 and viscous husky roller 6.
As seen in figures 3-5, the utility model includes reductor 1, weighing sensor 2, bearing block 3, roller 4, guide rail 5, viscous
Husky roller 6, sprocket wheel 7, lifting mechanism 8, the 3rd roller 9, go out car lifting device 10, braking force sensor 11 and frame 12, left and right
Two reductors 1 are arranged at the both ends of frame 12, glue husky roller 6 and connect reductor 1, the viscous husky rolling of the connection of sprocket wheel 7 by bearing block 3
Cylinder 6, two are glued and are provided with the 3rd roller 9 between husky rollers 6 and go out car lifting device 10, and the outside for gluing husky roller 6 is provided with system
Dynamic pickup 11, the lower section for going out car lifting device 10 are provided with weighing sensor 2 and roller 4, and roller 4 is placed on guide rail 5, led
Rail 5 is angularly disposed, and roller 4 can be scrolled up along guide rail 5, and lifting mechanism 8 is installed on the base of frame 12.
The effect of lifting mechanism 8 is to realize the lifting of frame 12, and for general preferable hydraulic cylinder as lifting mechanism 8, it can
To provide larger bearing capacity, and stable performance.Lifting mechanism 8 connects hydraulic pump, and provides driving force by hydraulic pump.
Reductor 1 connects motor, and drives its rotation by motor.
As to further explanation of the present utility model, now illustrate its course of work：
The first step：Tested vehicle is driven into the utility model, secondly axle wheel 14 falls into two of the present utility model viscous sand
Between roller 6, after vehicle comes to a complete stop, go out car lifting device 10 and decline, be in close contact between two-axle car wheel 14 and viscous husky roller 6.Car
Neutral is linked into, hydraulic pump drive lifting mechanism 8 is started working, so as to drive frame 12 to begin to ramp up, when frame 12 rises to
During 100mm height, lifting mechanism 8 is stopped, and the height of frame 12 is maintained at 100mm.Now only has two-axle car wheel 14 with gluing
Husky roller 6 contacts, and an axle wheel 13 and three axle wheels 15 keep half vacant state slightly off ground.This process is just completed
The function of loading, the size of loading force are measured by weighing sensor 2.State after loading is as shown in Figure 5.
Second step：The reductor 1 of left and right two at the both ends of frame 12 by motor drive and rotate, reductor 1 drives
Glue husky roller 6 to operate with 5km/h linear resonance surface velocity, while two-axle car wheel 14 also drives the 3rd roller 9 to operate.Treat that operating is stable
Afterwards, system prompt driver " touching on the brake ", now the 14 rapid locking of two-axle car wheel, the 3rd roller 9 shut down.3rd rolling
Triggering Control System sends instruction after cylinder 9 shuts down, and stops the motor power for driving reductor 1 to operate, and motor stops
Operating.
3rd step：Start hydraulic pump, hydraulic pump drive lifting mechanism 8 falls frame 12, when frame 12 drops to horizontal position
When putting, hydraulic pump is stopped.
4th step：Go out car lifting device 10 to rise, after abundant rise, vehicle rolls the utility model away from, and detection is completed.
The utility model the Level Promoting frame 12 of lifting mechanism 8, makes roller 4 along guide rail 5 by setting lifting mechanism 8
Advance, so that frame 12 while moving horizontally, completes motion vertically upward, advantage of this is that thrust quilt
It is exaggerated, reduces the requirement to hydraulic pump and lifting mechanism 8, lifting mechanism 8 and liquid is also reduced while cost is reduced
The volume of press pump.Simultaneously by setting lifting mechanism 8, two-axle car wheel 14 can be made to be contacted with gluing husky roller 6, and an axle wheel 13
With three axle wheels 15 slightly off ground, half vacant state is kept, the gravity of detected two-axle car wheel 14 is acted on completely
On the viscous husky roller 6 of brake detection table, the adhesive force between increase two-axle car wheel 14 and viscous husky roller 6, it can detect exactly
Go out the brake force of multiple-axle vehicle, truly reflect the braking ability of multiple-axle vehicle.
Embodiment of the present utility model is explained in detail above in association with accompanying drawing, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, it is right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall within the scope of protection of the utility model.
