Abstract
The utility model relates to a speed ratio detector for detecting the consistency of the speed ratio between an intermediate axle and a back axle of double bridge driving automobile. The speed ratio detector of the utility model, on basis of the car speed measuring device, is provided with an inducing device on the roller surface of the intermediate axle and the back axle, wherein, the neighborhood of the intermediate axle roller and the back axle roller is respectively provided with a proximity switch which is connected with a double counter through a control switch. The beneficial effects of the utility model are convenient detection, short time consumption, easy manipulation and judgment, and the share of one speed stage with car speed detection in the car detecting field.
Description
(1) technical field
The utility model relates to a kind of car load speed ratio determinator, particularly a kind of speed ratio determinator that is used for doube bridge driving automobile.
(2) background technology
At present, doube bridge drives a kind of important type of drive that has become heavy motor vehicle, the speed ratio of vehicle bridge is different again, the speed ratio of two groups of drive axles of doube bridge driving automobile must be identical on request, but the speed ratio assembling that causes driving doube bridge owing to a variety of causes is wrong, causes the tire of drive wheels sharply to wear and tear.The speed of a motor vehicle is slow, and oil consumption is big, brings loss to client, causes claim expense to enterprise, but detection line does not have this measuring ability at present, can't effectively discern detection.
(3) summary of the invention
The utility model is for remedying the deficiencies in the prior art, and whether provide a kind of speed ratio that can not only measure doube bridge driving automobile accurately to assemble consistent, and identification form, doube bridge driving automatically, also is provided with the speed ratio determinator of warning device.
The utility model is achieved through the following technical measures:
Speed ratio determinator of the present utility model, on the basis of measuring vehicle speed device, in, the surface of back axle cylinder respectively installs an inductor, in, respectively install one near the back axle cylinder near switch, be connected with two counting machines by each master cock respectively near switch.
Speed ratio determinator of the present utility model in order to realize auto alarm, connects a buzzer phone on the jackshaft counting machine.
Speed ratio determinator of the present utility model, employed counting machine are two presetting systems, dual output counting machine.
For fear of all suffering very big loss because of the inconsistent user of causing of speed ratio assembling and enterprise, the utility model provides a kind of speed ratio determinator, whether the speed ratio that it can not only measure doube bridge driving automobile accurately assembles consistent, and identification form, doube bridge drive automatically, also are provided with warning device.
The technical scheme that its technical matters that solves the utility model adopts, realize by measuring wheel revolutions, easy to operate, when not increasing original detection time, utilize the existing speed of a motor vehicle resource that detects, being converted into by the suspend revolution of its wheel cylinder of mensuration and going to realize by detecting wheel revolutions, in, respectively install one near the back axle cylinder near switch, therein, each cylinder of back axle pastes an inductor, make each series cylinder revolution cross a circle, just can respond to once near switch, each connects a counting machine near switch by each control setup, write down the number of turns that each series cylinder turns over, by in, the radius of back axle cylinder, can calculate, when the speed ratio assembling is consistent, when the back axle cylinder turns over a fixing turn, the jackshaft cylinder must turn over a certain number of turns (this number of turns is a definite value), the counting machine of counting jackshaft cylinder connects a buzzer phone again, exceeding theoretical result calculated in error limit after, the number of turns that the rolling bridge tube turns in the middle of making to report to the police, the signal transmission near between the counting machine of switch and counting back axle cylinder that the back axle cylinder is relative is controlled by the lift jack switch, and the counter controls of back axle cylinder is counted in the signal transmission near between the counting machine of switch and counting jackshaft cylinder that the jackshaft cylinder is relative by relay switch.
Speed ratio determinator of the present utility model, its key are that control two counting machines are opened simultaneously, turn-off simultaneously.Two counting machines adopt two presetting systems, dual output counting machine, and the two predetermined counters that near switch link to each other relative with the back axle cylinder are controlled by bay-lift.The effect of this counting machine has three.The one: preset the closed jackshaft cylinder of several one output signal that completely resets relative near transmission control unit relay between the counting machine of switch metering jackshaft cylinder revolution.The 2nd: preset several two full output signals open the jackshaft cylinder relative near transmission control unit relay between the counting machine of switch and metering jackshaft cylinder revolution.The 3rd,, the over effect that preset number together, really the counting that needs is to preset severally two, is to be benchmark to preset several two, calculates the number of turns that jackshaft cylinder need change in each radius roller ratio.The counting machine effect of metering jackshaft cylinder has two, and the one,, the numerical value of meter is the actual revolution of jackshaft cylinder, is the significant in value that we will compare with theoretical value.The 2nd,, preset several one and to preset several two are critical values that we report to the police.
The beneficial effects of the utility model are, in the vehicle inspection and test field can with detect the shared mouse of the speed of a motor vehicle, weak point easy to detect, consuming time, judgement easy to operate, easy.
(4) description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Accompanying drawing is a concrete connection structure scheme drawing of the present utility model.
Among the figure, 1 back axle wheel, 2 jackshaft wheels, 3 back axle cylinders, 4 jackshaft cylinders, 5 transmission shafts, 6 near switch A, and 7 near switch B, 8 lift jack mechanical switch K1,9 relay switch K2,10 buzzer phones, 11 counting machine A, 12 counting machine B, 13 inductors.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.Among the figure, in the speed of a motor vehicle test cell that existing car load detects, be positioned at jackshaft cylinder (4), respectively install one near the back axle cylinder (3) near switch B (7), near switch A (6), sensitive surface faces the section radius of cylinder, on the surface of cylinder one inductor (13) is installed respectively, the disc that installation site Ying Zaiqi turns over when rotating with cylinder with near the axis of switch at grade, and inductor rotary course middle distance is less than 80% of about set a distance of demarcating near switch near the minor increment of switch, back axle is connected with counting machine A (11) by mechanical switch K1 (8) near switch A (6), jackshaft is connected with counting machine B (12) by relay switch K2 (9) near switch B (7), each counting machine external AC 220V, the mechanical switch K1 (8) that links to each other with counting machine A (11) near switch A (6) of back axle cylinder is controlled by bay-lift, KI disconnects when rising to upper limit, K1 closure when dropping to lower limit, the relay switch K2 (9) that is connected with counting machine B (12) near switch B (7) of jackshaft cylinder is subjected to counting machine A (11) control, counting machine A presets several one when completely resetting, the K2 closure; Several two K2 when full that preset of counting machine A disconnect, and counting machine B connects a buzzer phone (10) again, and counting machine B counting is not just reported to the police in theoretical scope.
