[0003] However, when this type of drive axle structure realizes the differential lock function, it is necessary to realize the action of the shift fork by turning on and off the power of the electromagnet, so that the shift fork drives the clutch to make the two half shafts mechanically connected, which not only complicates the structure , and the clutches need to be installed and fixed on the differential case and the shaft sleeves of the half shafts, especially when such clutches are installed on both half shafts, it will further increase the complexity of the system, occupy a large space, and have a large mass. high cost

The invention discloses a power transmission system for a vehicle and the vehicle with the power transmission system. The power transmission system comprises a pair of wheels, a first electric power motor and a second electric power motor as well as an anti-skid synchronizer, wherein the wheels can rotate in a differential way; the first electric power generator is arranged to be linked with one of the wheels; the second electric power generator is arranged to be linked with the other one of the wheels; and the anti-skid synchronizer is arranged to selectively synchronize the pair of wheels so that the pair of wheels can synchronously rotate. According to the invention, a mechanical self-locking differential mechanism structure of the traditional power transmission system can be not arranged in the power transmission system; however, the function of the traditional mechanical self-locking differential mechanism can be realized through the synchronizing effect of the anti-skid synchronizer in function. Therefore, the power transmission system disclosed by the embodiment of the invention has the advantages of compact structure and low cost.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a power transmission system for a vehicle and a vehicle with the power transmission system. Background technique [0002] Chinese invention patent application (application number: 89209460.5) discloses a kind of automobile driving axle with differential lock. The automobile drive axle has components such as planetary gears, differential gears, half shafts, shaft sleeves, jaw clutches and shift forks. It is mainly to install the above-mentioned jaw clutch on one or two semi-shafts of the car. When the driving wheel of the car slips, the jaw clutch is controlled to work selectively with a shift fork to form a rigid connection between the two semi-shafts. , so that the differential locks and loses the differential function. [0003] However, when this type of drive axle structure realizes the differential lock function, it is necessary to realize the action of the shift fork b...
