Abstract

The invention discloses a torque detection device for a hub bearing. The hub bearing is arranged in a torque detection position; the hub bearing moves upwards under the action of a feeding device; a motor drives a driving shaft and a positioning mandrel to synchronously rotate, so that the positioning mandrel drives the inner ring of the automobile hub bearing to rotate; seals on the inner ring and outer ring of the automobile hub bearing rub each other, so that a torque is generated to drive the outer ring to rotate; under the action of the torque of a friction force between the outer ring and a torque pressing plate, the torque pressing plate and a torque weight-balancing plate rotate; and the torque weight-balancing plate rotates to generate a twisting force; the twisting force acts on a torque sensor; the torque sensor outputs a torque; and therefore, the rotating torque of the automobile hub bearing can be measured.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a torque detection device for a hub bearing. Background technique [0002] At present, as the product performance and quality requirements of national auto parts are getting higher and higher. There are more and more testing requirements for various parameters in the assembly and production process of automobile hub bearings, and the requirements are getting higher and higher. If the torque of the automobile hub bearing is too low, the sealing performance of the bearing seal will be poor, the bearing will fail quickly, and the bearing life will be reduced. If the torque of the car hub bearing is too high, the torque will be large when the car starts, the vibration will be large when the car starts, the comfort will be poor, and the energy consumption will be high. The torque of the automobile hub bearing is too high, the friction of the seal increases, the sealant wears quickly, the fail...
