The embodiment of the present application relates to a rear drive axle and a vehicle thereof, relating to the field of vehicle technology, the rear drive axle includes a rear drive axle body, a leaf spring bracket and an adjustment module; the leaf spring bracket is arranged on the rear drive axle body On the top, it is used to connect the rear drive axle body and the vehicle leaf spring; under the adjustment of the adjustment module, the leaf spring bracket and the vehicle leaf spring are staggered relative to each other, so as to adjust the angle between the rear drive axle body and the vehicle leaf spring. Through the adjustment module, the relative position of the leaf spring bracket and the vehicle leaf spring is adjusted. Since the leaf spring bracket is arranged on the rear drive axle body, the relative position of the vehicle leaf spring and the rear drive axle body can be adjusted at the same time, thereby changing the rear drive. The included angle between the bridge body and the vehicle axis is used to solve the problem of vehicle deviation, thereby avoiding the need to investigate the causes of vehicle deviation one by one when the vehicle deviation problem is found, which can save investigation time and can be quickly and accurately Solve the problem of vehicle deviation.

The embodiment of the invention provides a method, device and system for processing abnormal operations of a service platform. The method comprises the steps: at least one service request carrying a session marker is sent to the service plate, wherein the session marker is used for marking the life cycle of once communication interaction between a client and the service platform, and the communication interaction comprises at least one service request; the service platform records a service processing result corresponding to the session marker in a system log; the client applies the session marker to query abnormal operations in the life cycle of the once communication interaction. Therefore, in a process of the once communication interaction, the abnormal operations related to multiple services of multiple systems are queried, so that one-by-one check to each system is avoided, and all abnormal operation processing is obtained once; a processing flow is simplified, processing resources are saved, and the processing efficiency is improved.

The invention discloses a state detection apparatus and detection method for a lead of overhead contact line equipment. The apparatus comprises a plurality of detection modules and a signal processing device. The detection modules comprise lasers, fixation plates with divergent devices arranged in the middle, four-quadrant light cell panels and wireless transmission modules. The laser are fixed on a support at one end of the overhead contact line equipment, the fixation plates are fixed on the lead of the overhead contact line equipment, the four-quadrant light cell panels are installed on a support at the other end of the overhead contact line equipment, and the wireless transmission modules are connected with the signal processing device. When the lead of the overhead contact line equipment is not deviated, the centers of the emission light of the lasers, the centers of the divergent devices and the centers of the four-quadrant light cell panels are disposed at the same straight line. According to the method, whether the lead is deviated, a deviation direction and a deviation size can be calculated in accordance with the size of acquired voltage signals generated by each cell and the position relations among the lasers, the divergent devices and the four-quadrant light cell panels. The method has the advantages of simplicity, reliability, good real-time performance, low cost, convenient installation and easy maintenance.
