Abstract

The utility model discloses a drive axle reliability test bed, belongs to a detecting component of a drive axle for an engineering machinery and solves the problems of complex structure and higher cost of the drive axle reliability test bed in the prior art. The drive axle reliability test bed comprises a table board, a front chain wheel, a rear chain wheel, a transmission shaft and a motor. The front chain wheel is connected with the rear chain wheel by a chain. The transmission shaft is provided with a torque sensor and a driven belt pulley. The driven pulley is connected with a driving belt pulley on the motor by a belt. The front end of the drive axle reliability test bed is provided with an oil cylinder. The oil cylinder is fixed by an oil cylinder bracket. The transmission shaft and the oil cylinder bracket are arranged on the table board. The drive axle reliability test bed is mainly used for detection test of the drive axle for the engineering machinery.

Description

The drive axle reliability test bench
Technical field
The utility model belongs to the pick-up unit of a kind of engineering machinery with drive axle, specifically, relates in particular to a kind of drive axle reliability test bench.
Background technology
The reliability level of drive axle is directly connected to the reliability of car load.Because the road environment that vehicle is run in the process of moving is ever-changing, when especially vehicle travels on the road surface of injustice, the impact of collision that additional dynamic load that Vehicular vibration produced and road surface projection cause vehicle makes the stressed very complicated of drive axle, and working environment is extremely abominable.Drive axle is important assembly in the power train in all kinds of assemblies, and national sector standard regulation newly designs or has the drive axle typing of significant improvement to produce, or when carrying out the product quality examination, the reply drive axle carries out type approval test.As seen, the importance that drive axle is tested, wherein the torture test of drive axle assembly gear is the pilot project that the drive axle type approval test of drive axle bench test method (QC/T 533-1999) regulation must be carried out.The test objective of drive axle assembly gear torture test is the fatigue lifetime of check drive axle assembly gear.The reliability test bench of present drive axle has a variety of, is mostly to adopt speed reduction unit and braking motor and drive motor to load.Because drive axle has two wheel limits to carry out the moment of torsion braking, therefore needs two cover speed reduction unit and braking motors, its structure more complicated, cost is higher.
Summary of the invention
In order to solve drive axle reliability test bench complex structure in the prior art, the higher defective of cost, the utility model provides a kind of drive axle reliability test bench.
The utility model is achieved through the following technical solutions:
A kind of drive axle reliability test bench comprises table top, preceding sprocket wheel, back sprocket wheel, transmission shaft and motor, and preceding sprocket wheel and back sprocket wheel link by chain, and transmission shaft is provided with torque sensor and driven pulley; Driven pulley links to each other with driving pulley on the motor by belt; Front end of the present utility model is provided with oil cylinder, and oil cylinder is fixed by cylinder bracket; Transmission shaft and cylinder bracket are installed on the table top.
Compared with prior art, the beneficial effects of the utility model are: adopt hydraulic jack to the front driving axle applied thrust, the reach of promotion front driving axle, make the chain tensioner, adopt the rotation of driven by motor front driving axle and rear driving axle simultaneously, thereby make the gear train of front driving axle and rear driving axle inside bear certain torque value, realize front driving axle and rear driving axle imposed load, thereby reach testing requirements; Simple in structure, afterburning effect is obvious, only drives the running of whole test platform with a drive motor, and use cost is low, has reached the requirement of drive axle fail-test.
Description of drawings
Fig. 1 is a vertical view of the present utility model;
Fig. 2 is a front view of the present utility model;
Fig. 3 is user mode figure of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Preceding sprocket wheel in the drawings, 1; 2, cylinder bracket; 3, motor; 4, front driving axle; 5, chain; 6, oil cylinder; 7, torque sensor; 8, belt; 9, transmission shaft; 10, rear driving axle; 11, back sprocket wheel; 12, table top.
A kind of drive axle reliability test bench comprises table top 12, preceding sprocket wheel 1, back sprocket wheel 11, transmission shaft 9 and motor 3, and preceding sprocket wheel 1 and back sprocket wheel 11 are by chain 5 links, and transmission shaft 9 is provided with torque sensor 7 and driven pulley; Driven pulley links to each other with driving pulley on the motor 3 by belt 8; Front end of the present utility model is provided with oil cylinder 6, and oil cylinder 6 is fixing by cylinder bracket 2; Transmission shaft 9 and cylinder bracket 2 are installed on the table top 12.
In use, front driving axle 4 and rear driving axle 10 are installed in rear and front end of the present utility model respectively, then preceding sprocket wheel 1 and back sprocket wheel 11 are installed in respectively on front driving axle 4 and the rear driving axle 10, and link with chain 5.When work, apply certain thrust for the front driving axle 4 of test by oil cylinder 6, make chain 5 tensioners, increase load for the gear train of front driving axle 4 and rear driving axle 10 with this, simultaneously, the distortion situation of hub reduction gear on complete machine of simulation front driving axle 4 and rear driving axle 10, hub carrier etc., real simulated front driving axle 4 and rear driving axle 10 bad working environments and reach the torque value of designing requirement, read by torque sensor 7 torque value that gear train is suffered at last.By said process, effectively measured the test figure of front driving axle 4 and rear driving axle 10.
