The invention discloses an electric vehicle and a reduction gearbox thereof. The reduction gearbox comprises a box body, a transmission shaft, an anti-slip gear and an anti-slip claw assembly, wherein the transmission shaft is arranged in the box body; the anti-slip gear is sleeved on the transmission shaft and is driven to rotate by the transmission shaft; the anti-slip claw assembly is matched with the anti-slip gear; the anti-slip claw assembly is configured to be normally meshed with the anti-slip gear when the anti-slip gear rotates around the center axis of the transmission shaft in a first direction and be relatively locked with the anti-slip gear so as to prevent the electric vehicle from slipping when the anti-slip gear rotates around the center axis of the transmission shaft in a second direction. According to the reduction gear of the electric vehicle, disclosed by the embodiment of the invention, by arranging the anti-slip gear on the transmission shaft in the reduction gearbox and arranging the anti-slip claw assembly matched with the anti-slip gear, the electric vehicle is effectively prevented from slipping due to insufficient power, personal safety accidents are avoided, and safety performance of the electric vehicle is promoted.
Description
technical field [0001] The invention relates to the field of vehicles, in particular to an electric vehicle and a reduction box thereof. Background technique [0002] It is pointed out in related technologies that the cost and technology of electric vehicles are still immature. Due to the small torque, there will inevitably be a phenomenon of insufficient power and sliding slopes when the slope is large, which is prone to safety accidents, causing psychological and property damage to users. damage. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide a reduction box for an electric vehicle, which can effectively prevent the electric vehicle from sliding when going uphill, thereby improving the safety performance of the electric vehicle. [0004] Another object of the present invention is to provide an electric vehicl...
