Instrument for measuring startup torque, swing torque and slippage force of constant-velocity universal joint assembly

Abstract

The invention discloses an instrument for measuring a startup torque, a swing torque and a slippage force of a constant-velocity universal joint assembly. The instrument comprises an outer spherical-cage swinging shafting, an inner spherical-cage swinging shafting, and an outer spherical-cage rotating shafting and an inner spherical-cage rotating shafting which are arranged on the upper ends of the outer spherical-cage swinging shafting and the inner spherical-cage swinging shafting respectively, wherein an outer spherical-cage swinging motor for driving the outer spherical-cage swinging shafting to rotate is arranged at the lower end of the outer spherical-cage swinging shafting; an angle sensor is arranged on the outer spherical-cage swinging motor; an outer spherical-cage fixing device and an inner spherical-cage fixing device are arranged on the outer spherical-cage rotating shafting and the inner spherical-cage rotating shafting respectively; an assembly rotating motor for driving the outer spherical-cage rotating shafting to rotate is arranged at the other end of the outer spherical-cage rotating shafting; and an assembly torque sensor is arranged between the assembly rotating motor and the outer spherical-cage rotating shafting. By the instrument, the startup torque, swing torque, and slippage force, at a slippage end, of a constant-velocity universal joint assembly can be detected at the same time, the measurement precision is high, the measuring method is advanced and the operation is simple and convenient; and thus, the automatic measurement is achieved and current gap in the field is filled.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a measuring instrument for starting, swinging moment and slip force of a constant velocity universal joint assembly. Background technique [0002] With the development of the automobile industry, the quality requirements for auto parts are getting higher and higher. At present, the performance testing of the domestic automobile constant velocity universal joint assembly is almost blank, and only fatigue tests can be done without scientific and quantitative testing methods. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings and deficiencies of the above-mentioned prior art, and provide a constant velocity universal joint assembly startup, swing torque and slip force measuring instrument, which can simultaneously detect the constant velocity universal joint assembly Starting torque, swinging torque and slip force at the slip end have hi...
