Description

For the test unit that driving axis bevel gear meshing mark loads
Technical field
The utility model relates to a kind of test unit, especially relates to a kind of test unit loaded for driving axis bevel gear meshing mark, belongs to automobile making facilty design manufacturing technology field.
Background technology
Main reducing gear of drive axle is in car transmissions, play reduction rotating speed, increases the critical piece of torque, also has the effect changing torque sense of rotation when engine is longitudinal.It relies on the few gear of the number of teeth and main cingulum to move the many gears of the number of teeth namely to realize slowing down from tooth, adopts bevel gear drive then can change torque sense of rotation.Main reducing gear is arranged in power to the position before driving wheel shunting, is conducive to reducing drive disk assembly before it as clutch coupling, variator, transmission shaft etc., the torque of transmitting, thus the size and the quality that reduce these parts.
Main reducing gear of drive axle divides by the gear pair number participating in gearing-down, can be divided into single stage type main reducing gear and stage type main reducing gear.Except the Medium or severe type car employing double reduction final drive of ask for something big speed ratio, generally micro-, light, in-between car adopts single reduction final drive substantially.Single reduction final drive is exactly a drive bevel gear and a driven bevel pinion, and drive bevel gear connection for transmission axle, turns clockwise, and driven bevel pinion is attached on the right side of it, and meshing point rotates, consistent with wheel working direction.Because active conical tooth wheel diameter is little, driven bevel pinion diameter is large, reaches the function of deceleration.
The main reducing gear of Hyundai Motor, extensively adopts spiral bevel gear and hypoid gear.Hypoid gear stable working is good, bending strength and contact strength high, driving gear axis can be made to offset relative to follower gear axis.When driving gear shaft line offsets downward, the position of transmission shaft can be reduced, thus be conducive to reducing vehicle body and car load height of C.G., improve the riding stability of automobile.During hypoid gear work, the pressure between the flank of tooth and slip are comparatively large, and flank of tooth oil film is easily destroyed, and must adopt hypoid gear oil lubrication, never allow with the replacement of ordinary gear oil, otherwise the flank of tooth will be made to abrade rapidly and wear and tear, greatly reduce serviceable life.
For bevel gear, its impression contact region is one and closes emphasis.The size of impression contact region, position influence gear teeth face load diatibution, and then play decisive role to the intensity of gear and running stability, finally affect the life-span of gear and the NVH performance of main gearbox assembly.For the requirement making processing and manufacturing bevel gear out meet meshing mark, thus ensure its life-span and NVH performance etc., find a kind of test unit detecting main reducing gear of drive axle bevel gear meshing mark to become research direction in field.
Utility model content
Technical problem to be solved in the utility model is: provide the test unit loaded for driving axis bevel gear meshing mark that a kind of energy simulated automotive running status loads to driving axis.
For solving the problems of the technologies described above adopted technical scheme be: a kind of test unit loaded for driving axis bevel gear meshing mark, comprise driving mechanism, load maintainer, control system and coupling assembling, described load maintainer and described driving mechanism are respectively by dismountable clutch end and the power intake being fixedly connected on described driving axis of described coupling assembling, and the starting of described driving mechanism and the loading of described load maintainer control respectively by described control system.
Be further, described driving mechanism comprises drive motor, planet-cycloid reducer and wheel box, the power wheel that described wheel box and described drive axle portion become enters to hold and is connected, and described drive motor is connected with described wheel box by described planet-cycloid reducer.
Further, described load maintainer is made up of two detents be arranged on respectively on described driving axis two clutch ends.
Further, described detent is magnetic powder brake.
Be further, described coupling assembling is made up of the transmission shaft that many contain shaft coupling, and each described transmission shaft is arranged between described driving mechanism and described driving axis power intake and between described load maintainer and the clutch end of described driving axis by described shaft coupling.
Further, described test unit also comprises containing backed Working Table, and described driving mechanism, described load maintainer and described driving axis are fixed in described Working Table by described bearing.
Further, described Working Table longitudinally with is laterally respectively arranged with T mounting groove, and described bearing can be arranged in described Working Table by described T mounting groove as required.
The beneficial effects of the utility model are: by arranging a test unit be made up of driving mechanism, load maintainer, control system and coupling assembling, then by described load maintainer and described driving mechanism respectively by dismountable clutch end and the power intake being fixedly attached to described driving axis of described coupling assembling, and the loading of the starting of described driving mechanism and described load maintainer is controlled respectively by described control system.Like this, at the trial, just can by the driving mechanism simulated engine of described test unit, load maintainer simulating wheel, under the control of described control system, described driving axis is carried out to the load test of motoring condition, reach the object detected by the meshing mark of the bevel gear of test driving axis.
