Abstract
The invention discloses a wheel limit device used when testing the brake performance of an automobile. The device comprises a base (1), a locating pole (2) and a catch wheel (3), wherein the lower end of the locating pole (2) is connected onto the upper end face of the base (1), and an upper annular table (4) and a lower annular table (5) are sleeved upon the upper end of the locating pole (2). The catch wheel (3) comprises a cylinder and a sealing cover plate, a round penetrating hole is formed in the sealing cover plate of the catch wheel (3), the locating pole (2) penetrates through the round penetrating hole of the sealing cover plate, and the sealing cover plate is sleeved upon the locating pole (2) between the upper annular table (4) and the lower annular table (5). A wheel can be limited and guided by the catch wheel (3) when the wheel limit device is applied to a brake test table, so that the wheel deviating from a simulated road is avoided, and the influences of artificially regulating the wheel on the test efficiency is avoided.
Description
Technical field
The present invention relates to a kind of servicing unit that detects automobile brake perfrmance, specifically wheel is carried out to spacing device when checking automobile brake perfrmance.
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 at this moment 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, provide a kind of being arranged on Vehicles Brake Test Bench to carry out spacing to the wheel of automobile, can avoid wheel to depart from simulated roadway, so improve checkability wheel is carried out to spacing device when checking automobile brake perfrmance.
Object of the present invention is achieved through the following technical solutions: wheel is carried out to spacing device when checking automobile brake perfrmance, comprise base, backstay and gear wheel, described backstay lower end is connected in base upper surface, and backstay upper end is arranged with annular table and is positioned at the lower annular table of annular table below; Described gear wheel is comprised of a cylinder and the blank cover that is connected in this cylinder upper end, the blank cover central part of described gear wheel is provided with the circular perforations that runs through its upper and lower end face, the internal diameter of this circular perforations is less than the outer shroud circular diameter of annular table and lower annular table, described backstay is through the circular perforations of blank cover, and blank cover is set on the backstay between annular table and lower annular table.When the present invention applies, be fixed between two cylinders of Vehicles Brake Test Bench, quantity of the present invention be set between two cylinders and should be two, when specifically arranging, the present invention should be near the tip position of cylinder.
For fear of wheel, contact with rectangular base, described base forms rectangular shape, and the barrel bore of described gear wheel is greater than the width of base upper surface.
For the ease of gear wheel is changed, described backstay upper end is provided with external thread, and the ring inwall of described upper annular table is provided with the internal thread mating with backstay external thread.
For the ease of the present invention, be fixed on automobile inspection bench, described base is provided with the threaded hole that runs through its upper and lower end face.So, the present invention can be bolted on Vehicles Brake Test Bench, fixing and convenient disassembly.
Compared with prior art, the present invention has following beneficial effect: gear wheel of the present invention is set on backstay, when being applied on Vehicles Brake Test Bench, the present invention is fixed between two cylinders, and the tip position near cylinder, when wheel is during near cylinder tip position, wheel contacts with gear wheel, under the effect of keeping out of gear wheel, wheel changes rotating direction and gets back to gradually the simulated roadway central authorities that cylinder forms, and wheel and gear wheel are when interact, under the drive of wheel, gear wheel rotates around backstay, on backstay, be arranged with annular table and lower annular table is carried out spacing up and down to gear wheel, under the rotary action of gear wheel, between gear wheel and wheel, rigid friction reduces, and then make gear wheel to wheel carry out spacing and when guiding gear wheel and wheel not fragile, by gear wheel of the present invention, wheel is carried out to spacing and guiding, can avoid wheel to depart from simulated roadway, do not need staff to adjust people's wheel, improved checkability.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is the decomposition texture schematic diagram of Fig. 1.
In accompanying drawing, the corresponding name of Reference numeral is called: 1, base, 2, backstay, 3, gear wheel, 4, upper annular table, 5, lower annular table.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Embodiment:
As shown in Figures 1 and 2, wheel is carried out to spacing device when checking automobile brake perfrmance, comprise base 1, backstay 2 and gear wheel 3, wherein, base 1 forms rectangular shape, and backstay 2 lower ends are connected in base 1 upper surface central part.For the ease of the present embodiment, be fixed on Vehicles Brake Test Bench, base 1 is provided with a plurality of threaded holes that run through its upper and lower end face, as preferably, the quantity of the threaded hole that base 1 arranges is four, and the opening that four threaded holes are positioned at base 1 upper surface is distributed in respectively four right angle corner places of rectangular base 1 upper surface.
As mentioned above, can well realize the present invention.
