Description
Technical field
The present invention relates to detect the device of automobile brake perfrmance, specifically can prevent that wheel from departing from the Vehicles Brake Test Bench of simulated roadway.
Background technology
Along with popularizing of automobile, the security performance of automobile detects and is more and more subject to people's attention, and in the braking ability checkout procedure of automobile, can be checked with two kinds of modes of check-out console check and be carried out by road.Wherein, when testing on road, automobile brake perfrmance needs larger place, the serious wear of doughnut, and proving time is long, efficiency is low, is not easy to apply.The equipment that conventional check-out console inspection institute uses is drum reaction brake test bench, drum reaction brake test bench is as simulated roadway by motor-operated cylinder, tested wheel is placed on two cylinders, and cylinder, by direct motor drive, drives rotation of wheel.When applying braking to wheel, wheel is to one, cylinder and driving direction opposite effect power, and this power and damping force equal and opposite in direction, opposite direction, measure this power with sensor, can reflect the size of the damping force that wheel can produce.
After cylinder carrying wheel on existing drum reaction brake test bench, in the process of drum rotating, wheel easily departs from the simulated roadway that cylinder forms, and needs operating personnel to adjust wheel, this just makes checkout procedure become loaded down with trivial details, and has affected checkability.
Summary of the invention
This practical purpose is to overcome the deficiencies in the prior art, provides a kind of and can carry out the wheel of automobile spacingly, can avoid wheel to depart from simulated roadway, and then the prevented wheel that improves checkability departs from the Vehicles Brake Test Bench of simulated roadway.
Object of the present invention is achieved through the following technical solutions: can prevent that wheel from departing from the Vehicles Brake Test Bench of simulated roadway, comprise frame, described frame is provided with the two groups of brake inspection devices in left and right, two groups of brake inspection devices include head roll and with the driven cylinder of the parallel placement of head roll, driven cylinder two ends respectively with head roll justify align, between described head roll and driven cylinder, be provided with supporting station, on supporting station, be provided with two stop means; Described stop means comprises base, positioning pipe and columned gear wheel, described positioning pipe one end is connected in the upper surface of base, described gear wheel inside is provided with the cavity that vertically arranges and connect its lower surface, gear wheel is connected with turning axle, the upper end of described turning axle is positioned at the cavity of gear wheel, described positioning pipe upper end embeds in the cavity of gear wheel, and turning axle lower end embeds in positioning pipe.
The position of two stop means in every group of brake inspection device on supporting station be the two ends of close head roll respectively.Because of driven cylinder two ends in every group of brake inspection device respectively with head roll justify align, when two stop means are arranged on supporting station also respectively near driven cylinder two ends.
One end that described head roll and driven cylinder are positioned at frame central authorities is equipped with sprocket wheel, and in every group of brake inspection device, the sprocket wheel of head roll and driven cylinder is connected by roller chain; The other end that described head roll is provided with sprocket wheel end is relatively connected with roller bearing, and described roller bearing is connected with drive motor after by the reducer casing of built-in speed reduction unit.
Described frame upper surface is connected with two limit cover plates that are positioned at the inter panel of its central part and are positioned at its two ends.
Compared with prior art, the present invention has following beneficial effect: when (1) the present invention applies, the left and right wheels of automobile is placed on respectively on the simulated roadway that in two brake inspection devices, head roll and driven cylinder form, when automotive wheel moves to simulated roadway two ends, now can change the direction of motion of wheel during the sidewall contact of wheel and gear wheel, and then avoid wheel to depart from simulated roadway, the present invention is regulated and controled the direction of motion of wheel by stop means when wheel touching stop means, easy to operate, and do not need operator to get involved adjustment wheel position, can improve checkability.
(2) gear wheel of the present invention can rotate with turning axle under the induced effect of wheel in positioning pipe, under the rotary action of gear wheel, between gear wheel and wheel, rigid friction reduces, and then gear wheel or wheel is caused to damage can avoid gear wheel to carry out spacing and guiding to wheel time.
