A motorized vehicle includes a multi-speed transmission having a plurality of forward gears configured to be selectively engaged to drive the motorized vehicle, an internal combustion engine selectively coupled to the transmission, and a reverse drive system selectively coupled to the transmission to provide torque to drive the motorized vehicle in a reverse direction. The reverse drive system includes an electric motor and a reverse drive gear train configured to be selectively coupled to the transmission. The transmission includes a neutral position in which the internal combustion engine is decoupled from the transmission and freely rotatable relative to the transmission. The reverse drive gear train is configured to be operably coupled to the transmission when the transmission is in the neutral position, such that the reverse drive system is operable to drive the motorized vehicle in the reverse direction without interference from the internal combustion engine.

The invention discloses a data processing method and device for intelligent grinding, and belongs to the technical field of electric digital data processing, and the method comprises the steps: obtaining weight sampling values of a plurality of sampling points at the driving tail end of a reverse driver transmitted by sampling; obtaining a trend coefficient of the weight sampling value of each time point in the sampling value queue of each sampling point, and according to the trend coefficient, obtaining the corrected disturbance amplitude of the weight sampling value of each time point; obtaining the weight of the weight sampling value of each sampling point at each time point; and checking the weight sampling values of all the sampling points at each time point according to the weights of the weight sampling values at each time point of each sampling point to obtain the weight value of the grinding machine. The defect that in the prior art, the weight value sampling precision of the grinding machine for intelligent grinding can be weakened due to the fact that the average number of the weight values on all the sampling points serves as the weight value of the grinding machine for intelligent grinding is effectively overcome.

A clutch for preventing backdrive includes a housing, a cover portion located at one end portion of the housing, an external shaft, at least a portion of which is located in the housing, and another end portion of which passes through the housing, a plurality of lockers located inside the housing and surrounding the first end portion of the external shaft, an input shaft, a first end portion of which is inserted into openings of the plurality of lockers and a second end portion of which is configured to pass through the cover portion, and a brake unit configured to be selectively engaged to the lockers to restrict rotations of the lockers. The external shaft is restricted by the lockers so that the external shaft and the lockers are rotated in a rotation direction of the input shaft, and movements of the lockers are restricted by the brake unit when the external shaft is rotated.
