The invention discloses an automobile brake detection platform, which comprises a left front roller assembly, a left rear roller assembly, a right front roller assembly and a right rear roller assembly installed on the ground through a bearing seat. The shaft of the left rear drum assembly is connected with the shaft of the right rear drum assembly successively through the left shaft coupling, the clutch and the right shaft coupling. This detection platform can better simulate the motion relationship between the ground and the left and right wheels, and the detection results are more accurate and reliable.
Description
Technical field
The present invention relates to a kind of automobile brake detection platform.
Background technology
Existing automobile brake detection platform, its main composition are by the surface-based left front roller assembly of bearing seat, right front roller assembly, left back roller assembly and right back roller assembly.Revolver with automobile during detection places between the left front and left back roller assembly, and right wheel places between the right front and right back roller assembly.Left back and right latter two cylinder rotation drives revolver and right wheel respectively.After revolver and right wheel reach certain rotating speed, left back and right latter two cylinder stops outputting power, left and right wheels and cylinder continue rotation under inertia effect, operate the brake system braking of automobile then, friction force by brake system makes wheel and cylinder stop motion, measure the distance that left and right wheels braking time and left and right sides cylinder rotate respectively during braking, can realize the detection of vehicle right and left wheel braking ability.Its left and right wheels of this detection platform and left and right sides cylinder thereof are independent fully; And actual automobile is in the braking procedure of ground run, and left and right to take turns braking independent.When braking as revolver, ground and right wheel will inevitably rub, and right wheel is also braked.Otherwise right wheel braking also can influence the motion of revolver; Only under the identical situation of the damped condition of left and right wheels, just may not influence each other.Therefore, the cylinder of existing automobile brake detection platform can not well be simulated the kinematic relation between ground and the automotive wheel, thereby the true braking ability of its testing result and automobile exists than mistake.
Summary of the invention
Purpose of the present invention just provides a kind of automobile brake detection platform, and this kind detection platform can be simulated the kinematic relation between ground and the left and right wheels better, and testing result more accurately, reliably.
The present invention realizes that the technical scheme that its goal of the invention adopts is, a kind of automobile brake detection platform, comprise by the surface-based left front roller assembly of bearing seat, right front roller assembly, left back roller assembly and right back roller assembly, it is characterized in that: the axle of described left back roller assembly links to each other with the axle of right back roller assembly by Left-wing Federation's axial organ, clutch coupling, right shaft coupling successively.
Compared with prior art, the invention has the beneficial effects as follows:
Left back and the right back roller bearings of detection platform of the present invention is connected by clutch coupling, and when revolver was braked, left back roller assembly rotating speed reduced, and by clutch coupling two frictional disk generation rubbing actions, makes the also corresponding reduction of rotating speed of right cylinder; With automobile when the ground run revolver is braked, ground can rub with right side wheel, it is close to make right wheel that the situation of braking also take place.In like manner, when right wheel was braked, its situation also situation with the right wheel braking of actual ground was close.Equally, only under the identical situation of the damped condition of left and right wheels, clutch coupling just can not had an effect, and does not influence each other between the left and right wheels yet.Therefore, automobile brake detection platform of the present invention can well be simulated the kinematic relation between ground and vehicle right and left wheel and the left and right wheels, thereby its testing result can reflect the true braking ability of automobile better, and its testing result is true more, reliable.
Above-mentioned clutch coupling is the clutch coupling of snap-in force between scalable platen and the friction disc.
Like this can be by regulating snap-in force between platen and the friction disc, and then the value of the power transmitted of adjusting, setpoint clutch, make its relation that reflects friction force between various ground and the automotive wheel better, further improve correctness, reliability that automobile brake perfrmance detects.
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.

Embodiment
Embodiment
Fig. 1 illustrates, and a kind of embodiment of the present invention is that a kind of automobile brake detection platform comprises by bearing seat 5 surface-based left front roller assemblies 1, left back roller assembly 3, right front roller assembly 2, right back roller assembly 4.The axle of described left back roller assembly 3 links to each other with the axle of right back roller assembly 4 by Left-wing Federation's axial organ 6, clutch coupling 7, right shaft coupling 8 successively.
This routine clutch coupling 7 is the clutch coupling of snap-in force between scalable platen and the friction disc.Regulate holddown spring to regulate the mechanical type adjustable clutch of the snap-in force between platen and the friction disc as powder clutch or by set screw.
