Half-shaft torque calibration device and working method thereof

Abstract

The invention discloses a half-shaft torque calibration device and a working method thereof. The device comprises a base, wherein sliding rails are arranged at two ends of a rear end of the top of thebase, a balance trolley is connected into the sliding rail in a sliding manner, a hydraulic press is fixedly mounted in the middle of the bottom of the balance trolley, a fixed shaft is slidably connected with the middle of the bottom of a hydraulic device, the top of the balance trolley is fixedly connected with a connecting seat, a front end of the top of the connecting base is fixedly connected with a supporting back plate, a lower part of the rear side of the supporting back plate is fixedly connected with a fixed rib plate, an upper portion of a front end of the supporting back plate isrotationally connected with a supporting bearing outer ring, and an inner ring of the supporting bearing is fixedly connected with a connecting shaft. The half-shaft torque calibration device is advantaged in that the balance dolly and the electric dynamometer are used to carry out a semi-axis calibration test on the semi-axis, the whole structure is simpler than that of a semi-axis calibration test machine, the device is arranged on a pedestal, the occupied area of the pedestal is relatively small, and the whole device can be dismounted after the device is used.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a half-shaft torque calibration device and a working method thereof. Background technique [0002] The half shaft is also called the drive axle. The half shaft is a solid shaft that transmits torque between the differential and the driving wheels. Its inner end is generally connected to the half shaft gear through splines, and its outer end is connected to the hub. Automotive torque is the torque output by the engine from the crankshaft end. Under the condition of fixed power, it is inversely proportional to the engine speed. The faster the speed, the smaller the torque, and vice versa, it reflects the load capacity of the car within a certain range. Car torque, like power, is one of the main indicators of an engine, reflected in car performance, including acceleration, climbing ability, and suspension. In the prior art, the method of static loading is often used to calibr...
