Abstract
The present utility model discloses an automobile brake detection device which comprises a left front roller assembly, a left rear roller assembly, a right front roller assembly, and a right rear roller assembly arranged on the ground through a bearing pedestal. A shaft of the left rear roller assembly is connected with a shaft of the right rear roller assembly after passing through a left shaft coupling, a clutch and a right shaft coupling successively. By adopting the detection device, the movement relation between the ground and the left and right wheels can be better simulated, and the detection result is more precise and reliable.
Description
Technical field
The utility model relates to the automobile brake pick-up unit.
Background technology
Existing automobile brake pick-up unit, its main composition are through 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, and the friction force through 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 pick-up unit 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 like 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 possibly not influence each other.Therefore, the cylinder of existing automobile brake pick-up unit 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.
The utility model content
The purpose of the utility model just provides the automobile brake pick-up unit, and this kind pick-up unit can be simulated the kinematic relation between ground and the left and right wheels better, and testing result more accurately, reliably.
The utility model realizes that the technical scheme that its goal of the invention adopted is; The automobile brake pick-up unit; Comprise through 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 through Left-wing Federation's axial organ, clutch coupling, right shaft coupling successively.
Compared with prior art, the beneficial effect of the utility model is:
Left back and the right back roller bearings of the utility model pick-up unit is connected through clutch coupling, and when revolver was braked, left back roller assembly rotating speed reduced, and through 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, the situation that makes right wheel also take place to brake is close.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, the automobile brake pick-up unit of the utility model 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 through 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 accompanying drawing and embodiment, the utility model is done further to specify.

Embodiment
Embodiment
Fig. 1 illustrates, and a kind of embodiment of the utility model is, the automobile brake pick-up unit comprises through the surface-based left front roller assembly of bearing seat 51, 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 through 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 like powder clutch or through set screw.
