Description
Technical field
The present invention relates to a kind of automotive inspection equipment, in particular it relates to a kind of for automobile flat type brake check-out console
Guiding mechanism and the Flat plate type brake check-out console.
Background technology
Automobile flat type brake check-out console is to be used to examine motor vehicle braking ability, is a kind of dynamic detecting equipment, test
When vehicle be that flat board is reached with certain speed, implement braking, the braking of each wheel then measured by sensor and measuring mechanism
Power and axle (wheel) weight.Because test process of the vehicle on automobile flat type brake check-out console is carried out in a dynamic state, therefore energy
The braking ability of vehicle is more practically reflected, and drum-type brake test bench compares, detection time is shorter, more efficient.
In detection process, the primarily longitudinal movement of platen is braked（That is direction of traffic）, but because detection pressure wheel exists
Brake on platen, axle（Wheel）Action of Gravity Field makes strain transducer bridge produce elastic deformation, system on the weighing sensor under flat board
Dynamic platen has downwards micro movement, if braking platen has close contact with the directive wheel in guiding mechanism, directive wheel will be applied
It is added on braking one upward frictional resistance of platen.Due to being dynamic detection, it is different to draw the speed that car person drives every time, traveling
Direction route is different, and the dynamics and time to touch on the brake is different, and which results in axle（Wheel）Gravity, braking forces measuring result
Repeatability is bad.
At present, the guiding mechanism of in the market automobile flat type brake check-out console mainly has two kinds, and Fig. 1 show bearing and led
To critical piece is made up of bearing, installation axle, shaft block ring, in detection process, if route or travel by vehicle is not and made
Longitudinal physical centre's line of dynamic platform is overlapped, and braking platen can be then in close contact with guide bearing, due to brake platen have downwards it is micro-
Amount movement, according to the principle of active force and reaction force, guide bearing reacts on braking one upward frictional resistance of platen,
So that actual measurement axle (wheel) tuple is not inconsistent according to actual axle (wheel) tuple evidence, and the difference of route or travel by vehicle and speed, it is oriented to
It is also different that bearing, which reacts on the upward frictional resistance of braking platen, and this is also to influence axle（Wheel）Gravity, braking forces measuring
As a result an important factor for repeated bad.Sphere directive wheel shown in Fig. 2 is oriented to, and critical piece is by sphere directive wheel, bearing, peace
Axle, back-up ring composition are filled, although the structure makes directive wheel be contacted with braking the contact surface of platen for point, but downward in braking platen
When having micro mobile, one upward frictional resistance of platen still can be given, equally influences whether to survey the true of axle (wheel) tuple evidence
Reality, accuracy.
Traditional guiding mechanism shown in Fig. 1 and Fig. 2 can only do scroll forward and backward with braking platen, it is impossible to scroll-up/down is done,
Because directive wheel and braking platen are up and down slips, frictional resistance is big, just have impact on authenticity, the accuracy of detection data.

A kind of automobile flat type brake check-out console, the brake test bench bag are additionally provided according to another aspect of the present invention
Include：Stand；Platen is braked, the braking platen is arranged on the stand；Multiple foregoing guiding mechanisms, the guiding
Mechanism is mounted in pairs on the stand in the both sides of the braking platen direction of traffic, for being carried out to the braking platen
It is oriented to and spacing；Multiple weighing sensors, the multiple weighing sensor are arranged on the stand, for measuring measuring car to be checked
Axle gravity and/or wheel gravity；With steel ball or roller, the steel ball or roller are separately positioned on the weighing sensor,
Braking platen is arranged on steel ball or roller, and the steel ball or roller are used to make braking platen move along direction of traffic, so as to reduce
Frictional resistance, and the vertical stress that will act on the braking platen are transferred to the weighing sensor.
Preferably, when the vertical stress is transferred to the weighing sensor, the weighing sensor strain bridge produces
Elastic deformation, move down braking platen.
Preferably, the guiding ball will can make caused non-horizontal non-vertical because the braking platen moves down
The reaction force of straight outer friction resistance transformation horizontally.
Preferably, the quantity of the weighing sensor is 4-8.
Preferably, the quantity of the steel ball or roller is consistent with the quantity of the weighing sensor.
By the guiding mechanism of the application present invention, under braking platen can be made upward, all directions such as front and rear it is smooth, accurate
