Description
Technical field
The present invention relates to the device detecting automobile brake perfrmance, specifically can prevent 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, checks two kinds of modes to carry out by road inspection and check-out console.Wherein, need larger place when automobile brake perfrmance is tested on road, the serious wear of doughnut, and proving time is long, efficiency is low, is not easy to apply.The equipment of conventional check-out console inspection institute is drum reaction brake test bench, drum reaction brake test bench is as simulated roadway by motor-operated cylinder, be placed on by tested wheel on two cylinders, cylinder is driven by motor, 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, direction are contrary, this power measured, can reflect the size of the damping force that wheel can produce with sensor.
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 is formed, and needs operating personnel to adjust wheel, this just makes checkout procedure become loaded down with trivial details, and have impact on checkability.
Summary of the invention
This practical purpose is to overcome the deficiencies in the prior art, provides a kind ofly to carry out spacing to the wheel of automobile, and wheel can be avoided to depart from simulated roadway, and then the prevented wheel improving 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 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 the follower rollers of head roll and placement parallel with head roll, follower rollers two ends respectively with head roll justify align, be provided with supporting station between described head roll and follower rollers, 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 to the upper surface of base, described gear wheel inside is provided with and vertically arranges and the cavity of connection gear wheel 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 often in group brake inspection device on supporting station is respectively near the two ends of head roll.Because of often to organize in brake inspection device follower rollers two ends respectively with head roll justify align, also respectively near follower rollers two ends when two stop means are arranged on supporting station.
One end that described head roll and follower rollers are positioned at frame central authorities is equipped with sprocket wheel, often organizes head roll in brake inspection device and is connected by roller chain with the sprocket wheel of follower rollers; The other end that described head roll is provided with sprocket wheel end is relatively connected with roller bearing, and described roller bearing is by being connected with drive motor after the reducer casing of built-in speed reduction unit.
Described frame upper surface is connected with the inter panel being positioned at frame central part and the two pieces of limit cover plates being positioned at frame 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 the simulated roadway that in two brake inspection devices, head roll and follower rollers are formed respectively, when automotive wheel moves to simulated roadway two ends, the direction of motion of wheel can be changed during the sidewall contact of now wheel and gear wheel, and then avoid wheel to depart from simulated roadway, the present invention is regulated and controled by the direction of motion of stop means to wheel when wheel touching stop means, easy to operate, and do not need operator to get involved adjustment wheel position, checkability can be improved.
(2) gear wheel of the present invention can rotate in positioning pipe with turning axle under the induced effect of wheel, under the rotary action of gear wheel, between gear wheel and wheel, rigid friction reduces, and then causes damage to gear wheel or wheel when gear wheel can be avoided to carry out spacing and guiding to wheel.
