Problems solved by technology

[0003] The technical problem to be solved by the present invention is that, for the existing wheel dynamic balancing machine, the dynamic unbalance detection data is unstable, the accuracy is low, there is a phase error that is unavoidable in the current technical situation, and the braking energy cannot be recovered and reused to provide a wheel dynamic balancing machine with stable dynamic unbalance detection data, high accuracy, which can reduce the phase error during unbalanced phase detection, and can recycle the braking energy for reuse

Abstract

An energy-saving wheel dynamic balancing machine belongs to the technical field of vehicle detection and maintenance. Including drive system, support system, detection system. It is characterized in that the driving system is a hydraulic driving system, and can realize a braking energy recovery device, including: a hydraulic pump, a hydraulic pump-motor, an electromagnetic reversing valve, a one-way valve, an overflow valve, and a bladder accumulator. When braking, the rotating shaft drives the motor to rotate, and the hydraulic oil is stored in the bladder accumulator through the control of the electromagnetic reversing valve, which can be reused for the next startup to realize the recovery of braking energy. The support system uses two bearings to be supported at close distances at two points and share a bearing seat to maximize the vibration signal generated by the wheel unbalance and transmit it to the hard support to improve the accuracy of detection. In the detection system, two vibration sensors are directly connected to the hard support to realize repeated detection and signal conversion of unbalanced quantities. The phase detection adopts a mechanical dot marking mechanism to minimize the phase detection error.

Description

technical field [0001] The invention relates to a wheel dynamic balancing machine and an energy-saving and detection method thereof, belonging to the technical field of automobile detection and maintenance. Background technique [0002] The wheel dynamic balancing machine is the most important and commonly used wheel maintenance and testing equipment. When testing and repairing the wheel, it is necessary to detect the size of the unbalanced mass and the phase of the unbalanced mass; the rigidity of the hard support of the existing wheel dynamic balancing machine Large, the support interval is large, which will disperse the transmission of unbalanced signals and affect the control of the minimum attainable remaining unbalanced mass; in the detection of wheel dynamic unbalanced mass, the more unbalanced signals generated by the unbalanced mass are detected, the The higher the detection accuracy, the sensor for detecting the unbalance signal of the existing wheel dynamic balanc...
