A Universal Axle Automatic Test Bench

Abstract

The invention relates to a general-purpose automatic test bench for vehicle axles, which is used for testing the performance of vehicle axles. The bridge strut is driven by the bridge body lifting component to move up and down. The test transmission area includes the running motor, transmission shaft system, adjustment base plate, rear end lifting adjustment mechanism and automatic docking assembly. The adjustment base plate is lifted by the rear end. The lifting adjustment mechanism adjusts the inclination angle, and the transmission shaft system adjusts the inclination angle through the automatic docking assembly. The transmission shaft system is driven to rotate by the running motor, and realizes automatic docking with the axle through elastic connectors. The advantages of the present invention are: the test bench can be automatically adjusted according to the different sizes and inclination angles of the vehicle axle, so that it can truly simulate the loading attitude of the vehicle axle, reduce the error of test data, and realize the automatic docking of the transmission shaft system and the input flange of the vehicle axle, reducing the Maintenance costs.

Description

technical field [0001] The invention relates to a vehicle axle test equipment, in particular to a general-purpose vehicle axle automatic test bench. Background technique [0002] Automobile axles, also known as axles, are connected to the frame or body through suspensions, and wheels are installed at both ends. The function of the axles is to bear the load of the car and maintain the normal driving of the car on the road. The automobile axle is an important component of the automobile. After the assembly is completed, the axle needs to undergo a series of inspections before entering the follow-up process. The existing inspections have special test benches for mass production. [0003] In the existing axle test bench, the drive shaft connected to the axle input flange is in a horizontal and fixed state. When testing some axle products with a certain inclination angle, the drive shaft and the axle input flange will have an assembly angle. , forming inertial swing under high s...

Problems solved by technology

[0003] In the existing axle test bench, the drive shaft connected to the axle input flange is in a horizontal and fixed state. When testing some axle products with a certain inclination angle, the drive shaft and the axle input flange will have an assembly angle. , forming inertial swing under high speed conditions, there is a certain safety hazard, and it is impossible to truly simulate the loading posture of the axle, and the experimental data of the test has certain errors compared with the loading and running data. High efficiency, the shafting on the existing test bench and the axle input flange need to be manually connected, and then manually disconnected after the test, which is time-consuming and labor-intensive

[0004] A Chinese invention patent with the publication number CN 103344440 B provides an axle test bench for the running-in test of the axle assembly. Transmission device, translation screw drive device and lifting and clamping device, etc., the test bench can automatically complete the grabbing, lifting, translation, putting in, lifting positioning, centering clamping and other actions of the axle assembly, which is automatic High degree, unmanned operation is realized. Although the test bench realizes the automatic engagement and separation of the test head and the main cone flange surface of the axle assembly through the translational screw drive device, the connection between the test head and the frequency conversion speed regulating motor The coupling between them is still in a horizontal state, which is not suitable for axles with a certain inclination angle, and the translation screw drive device is relatively cumbersome, and the maintenance cost is high
