Constant-speed ball cage universal joint contact force test bench and test method thereof

Abstract

The invention discloses a constant-speed ball cage universal joint contact force test bench, which comprises a tested constant-speed ball cage universal joint, a rotating speed control system, a load torque loading system, a working angle control system and a data acquisition system, and is characterized in that an auxiliary shell of the tested constant-speed ball cage universal joint is detachably connected with a main shell, and the auxiliary shell is provided with a ball groove; the rotating speed control system comprises a rotating speed driving part and a turntable unit; the working angle control system comprises a universal joint connecting tool and a sliding groove formed in the rotating disc unit, and the universal joint connecting tool is movably arranged in the sliding groove; the load torque loading system comprises a loading driving part, a first telescopic shaft and a second telescopic shaft; and the data acquisition system comprises an X-axis force sensor used for measuring a force signal in the X-axis direction, a Y-axis force sensor used for measuring a force signal in the Y-axis direction and a Z-axis force sensor used for measuring a force signal in the Z-axis direction. The invention further provides a corresponding testing method. According to the invention, experimental test analysis of the contact force of the constant-speed rzeppa universal joint is realized.

Description

technical field [0001] The invention belongs to the field of universal joints, and in particular relates to a test bench for testing the contact force of a constant velocity spherical cage universal joint and a testing method thereof. Background technique [0002] The constant velocity universal joint is the connecting part between the shaft and the shaft, mainly used in the occasion where the two shafts are different from each other, and satisfies the instantaneous constant velocity characteristics of the motion when transmitting power. Among them, the constant velocity spherical cage universal joint allows a large angular displacement between the two intersecting shafts, which meets the needs of the front wheels of the car to transmit torque and motion at large steering angles, so it is widely used in the front and rear drive shafts of passenger cars. To meet the steering requirements of the vehicle. As a part of the power system, the working condition of the constant vel...

Problems solved by technology

Although this analysis method can obtain ideal results, it is difficult to cut and process the bell-shaped shell, and the performance requirements for the three three-axis force sensors are very high. The signal of the force sensor needs to be exported to the data acquisition device through the slip ring

The entire test bench is extremely complex and costly, and the development of the test bench is very difficult
