Abstract
The utility model relates to a four-wheel detecting stage for brake performance of vehicle, which is used for solving the problem that the indoor bench frame of the prior art can not check the brake performance of the automobile which is provided with an ABS brake system. The utility model comprises an underframe and roller sets arranged on the underframe. The roller set comprises a driving roller and a driven roller which are parallelly arranged at interval. The driving roller of each roller set is transmitted and connected with a driving motor. The amount of the roller sets are four, and the four roller sets are respectively corresponding to the left wheel and the right wheel of the front shaft and the back shaft of the vehicle, wherein, the two roller sets of the left wheel and the right wheel of the front shaft are mutually paralleled with the two roller sets of the left wheel and the right wheel of the back shaft. The brake process of the vehicle is simultaneously checked by the four sets of rollers after adopts the structure so that the brake process of the vehicle during the process of running is really simulated, and the brake performance of the vehicle being provided with an ABS brake system is effectively checked.
Description
Technical field
The utility model relates to a kind of braking ability monitor station, particularly a kind of automobile brake perfrmance four-wheel monitor station.
Background technology
Progress and development along with auto industry, vehicle safety is more and more paid attention to by production firm and consumer, increasing gradually along with the introduction vehicle over nearly 2 years, anti-blocking brake system has been the most basic configuration of the medium-to-high grade car of various new production, and high-grade motor bus of part and lorry also starting apparatus prepare moving anti-lock braking system.As everyone knows, the braking ability of establishing when automobile is finalized the design in use can wear and tear, wears out, be out of shape variation gradually because of unit, the device of forming braking system.For ensureing the safety traffic of vehicle in use, impel the car owner to keep the intrinsic braking ability of automobile, the person of countries in the world responsible departments of the government requires regularly, forcibly to detect the braking ability of automobile.
At present, the detection for automobile brake perfrmance mainly is that actual road test and stand detect two kinds.Though it is directly perceived, easy that road examination detection automobile brake perfrmance has, and can reflect Automobile Dynamic braking ability in the vehicle traveling process truly, and not need factory building.Need possess special-purpose test roads and special-purpose test apparatus but the road examination detects, detection efficiency is low, is difficult to big, the wide In-Use Motor Vehicles annual examination of the amount that satisfies, the needs of annual test workload.Therefore, the braking of In-Use Motor Vehicles detection both at home and abroad all is to adopt indoor stand detection method.Indoor stand detection efficiency height, economy, safety can each braking abilities of taking turns of detection by quantitative.Indoor detection stand is generally two cylinder group on same straight line, and each cylinder group is made up of drive roll and driven cylinder, and drive roll and drive motor are in transmission connection.This indoor stand detection architecture is simple, easy to use, has obtained adopting widely in public security, traffic system.But this indoor stand can only be tested respectively automobile front axle or rear axle when detecting, and can not accomplish really to imitate can't detect the braking ability with abs braking system automobile by the braking procedure of automobile.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, and a kind of automobile brake perfrmance four-wheel monitor station that can reflect the detected ABS system braking ability of Automobile Dynamic braking ability in the vehicle traveling process truly is provided.
For achieving the above object, the utility model automobile brake perfrmance four-wheel monitor station, comprise underframe and arrangement cylinder group thereon, described cylinder group, comprise drive roll and driven cylinder that parallel interval is provided with, the drive roll of every series cylinder and drive motor driving coupling, described cylinder group are 4 groups, corresponding with forward and backward left and right wheel of automobile respectively, wherein two series cylinders of two series cylinders of the left and right wheel of front axle and the left and right wheel of rear axle are parallel to each other.
After adopting said structure, utilize four series cylinders to come simultaneously the braking procedure of automobile is detected, can really imitate the braking procedure in the vehicle traveling process, therefore can detect braking ability effectively with abs braking system automobile.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model automobile brake perfrmance four-wheel monitor station is further described.
Fig. 1 is the synoptic diagram of the utility model automobile brake perfrmance four-wheel monitor station.
Embodiment
With reference to Fig. 1, the utility model automobile brake perfrmance four-wheel monitor station, comprise underframe and arrangement cylinder group thereon, described cylinder group comprises drive roll 31 and the driven cylinder 32 that parallel interval is provided with, the drive roll 31 and drive motor 2 driving coupling of every series cylinder, described cylinder group is 4 groups, and corresponding with forward and backward left and right wheel of automobile respectively, wherein two series cylinders of two series cylinders of the left and right wheel of front axle and the left and right wheel of rear axle are parallel to each other.
After adopting said structure, utilize four series cylinders to come simultaneously the braking procedure of automobile is detected, can really imitate the braking procedure in the vehicle traveling process, therefore can detect braking ability effectively with abs braking system automobile.
As a further improvement on the present invention, described front axle two series cylinders and rear axle two series cylinders are separately fixed on two underframe, and wherein arbitrary underframe below is provided with rail plate 8; Between described two underframe, be connected with wheelbase regulating device, described wheelbase regulating device comprises roll adjustment drive motor 61, leading screw 62 and suitable with it mother lead screw 63, leading screw 62 and mother lead screw 63 are hinged on respectively on the underframe between described front axle two series cylinders and on the underframe between rear axle two series cylinders, roll adjustment drive motor 61 and leading screw 62 driving coupling.For the accurate distance between control antero posterior axis two wheelbases, above-mentioned rail plate can adopt linear guides, also distance measuring sensor can be installed on drive motor, thereby makes in the precision of the displacement time ± 1mm that can be controlled at 1mm/s.In order to guarantee cylinder group stability and measuring accuracy in test, in the support outside of traveling roller group bottom locking device 7 is installed, locking device can be arbitrarily can be with guide rail and the locked device of cylinder underframe.
For the contact condition that makes all size wheel (tire) that is supported on the cylinder is same as or approaches the road surface contact condition, and the transient equilibrium of moving cylinder is better, and described diameter of cylinder is 400～500mm.Diameter of cylinder of the present utility model adopts 477.5mm.
In order to improve the attachment coefficient of cylinder surface,, on described outer surface of cylinder, adopt plasma spraying technology to be shaped on the coating of high attachment coefficient as further improvement of the utility model.This sprayed coating is thin, attachment coefficient is high, helps improving the transient equilibrium of cylinder, and then is convenient to improve the rotating speed of cylinder.
