Description
Technical field
The invention belongs to vehicle performance test technical field, it is adaptable to the brake function test of vehicle, be specifically related to one
High-precision flat plate type brake test bench.
Background technology
The braking ability of vehicle is an important indicator in vehicle safety performance, is directly connected to traffic safety, and cuts
Real relation to life, property safety, so, brake function test occupies an important position in vehicle performance test field.At present
Vehicle performance test mechanism uses desk-top method that vehicle braking performances is detected, assessed substantially.Desk-top method detection equipment
Mainly have: anti-force type drum braking check-out console, Flat plate type brake check-out console.Automobile is when braking, before the effect of inertia force
Taking turns the pressure to braking platen to increase, the pressure of braking platen is reduced by trailing wheel, i.e. the axle load of automobile there occurs reach.With counter-force
Formula drum braking check-out console is compared, when automobile detects on Flat plate type brake check-out console, it is possible to reflect automobile brake truly
During axle load reallocation after braking effect.Meanwhile, Flat plate type brake check-out console is compared with anti-force type drum braking check-out console
Relatively simple in construction, drives without motor, there is, in kart context of detection, the advantage that other detection modes are incomparable.Along with
Being continuously increased of vehicles number, Flat plate type brake check-out console will certainly be rapidly developed.
For many years applicant is being engaged in the theoretical research in Vehicular intelligentization detection direction and actual application always, uses
The most all Flat plate type brake check-out console finished product, is installing, is debugging Flat plate type brake check-out console and vehicle detection practice process
In, find that existing Flat plate type brake check-out console exists design deficiency and causes braking forces measuring degree of accuracy not high enough.Wherein, compare
A typical phenomenon is, is examining and determine the detected value size of existing Flat plate type brake check-out console braking force sensor
Time, Flat plate type brake check-out console is in the case of zero load and load two kinds, when i.e. Flat plate type brake check-out console being applied vertical load
Brake force indicating value with do not apply two kinds of vertical load in the case of, apply the simulation system of formed objects to Flat plate type brake check-out console
Power, the indicating value that braking force sensor detects has bigger difference.This phenomenon explanation load is to Flat plate type brake check-out console
Substantially, magnitude of load can directly affect the standard of existing Flat plate type brake check-out console braking forces measuring to the impact of brake force test result
Really property.
Observe the phenomenon that test accuracy that existing Flat plate type brake check-out console in use occurs is not high enough, pass through
Set up automobile mechanical model on Flat plate type brake check-out console, existing Flat plate type brake check-out console is carried out force analysis and
Frame for movement simulation analysis, it has been found that braking forces measuring mechanism is as the core of Flat plate type brake check-out console,
Existing Flat plate type brake check-out console exists obvious design not enough, mainly includes following three points:
1, on the braking force sensor horizontal level of existing Flat plate type brake check-out console and braking platen between plane all
Having certain difference in height, some Flat plate type brake check-out console differences in height can reach 60mm, when this difference in height exists when, and car
Taking turns when braking braking above platen, bearing frame structure can be to braking while to braking force sensor transmission vehicle braking force
Force transducer produces certain moment thus produces moment of flexure, and this moment of flexure can affect the braking force sensor survey to vehicle braking force
Examination accuracy.
2, existing Flat plate type brake check-out console is mostly mounted with two beam type systems in the front end of support frame structure
Dynamic pickup, after Flat plate type brake check-out console equipment installation, braking force sensor and the stress point of support frame
Between must stay certain assemblage gap, be braked power detection time, wheel braking force by bearing frame structure passing to system
During dynamic pickup, can make bearing frame structure that braking force sensor is produced collision impact, this collision impact
The braking force sensor detection to vehicle braking force can be had a strong impact on.
3, part existing Flat plate type brake check-out console have employed the braking force sensor of tension and is avoided that collision impact,
But owing to the most only employing the braking force sensor of a tension, and it is arranged on flat board brake test bench longitudinal centre line
On, owing to Wheel centre distance is different and vehicle is dynamic check, it is impossible to ensure that wheel is just in flat board brake test bench is longitudinal
It is braked detection in the heart, braking force sensor can be formed the moment of flexure on a left side or the right side equally, test result can be produced and compare
Big impact, it is difficult to ensure that the test accuracy of vehicle braking force.
Summary of the invention
Obtain in general frame structure, wheel braking force equivalence transmission and brake force for existing Flat plate type brake check-out console
Take the design deficiency that the aspects such as mode exist, cause the problem that Flat plate type brake check-out console braking forces measuring precision is not high enough, this
