Amphibious vehicle with liftable suspensions

An amphibious vehicle with liftable suspensions, comprising:

• a vehicle body (1), a driving assembly (2) mounted inside the vehicle body (1), a front axle transmission assembly (3) mounted inside the vehicle body (1), and a rear axle transmission assembly (4) mounted inside the vehicle body (1);
• wherein the front axle transmission assembly (3) and the rear axle transmission assembly (4) are respectively arranged on two ends of the drive assembly (2), and the drive assembly (2) is in transmission connection with the front axle transmission assembly (3) and the rear axle transmission assembly (4);
• wherein the front axle transmission assembly (3) comprises:
• a front axle transmission box (31), wherein the front axle transmission box (31) is fixedly mounted inside the vehicle body (1), two ends of the front axle transmission box (31) are respectively mounted with front axle transmission shaft components (33), and the front axle transmission shaft components (33) are in transmission connection with the drive assembly (2);
• air springs (35), wherein the air springs (35) are disposed above the front axle transmission shaft components (33), respectively, and are configured to adaptively adjust a height of front axle and thereby automatically adjust, through being connected to a vehicle-mounted control system, the height of front axle according to different road conditions;
• wherein the rear axle transmission assembly (4) comprises:
• a rear axle transmission box (41), wherein the rear axle transmission box (41) is fixedly mounted inside the vehicle body (1), two ends of the rear axle transmission box (41) are mounted with first rear axle transmission shafts (43), and the first rear axle transmission shafts (43) are in transmission connection with the drive assembly (2);
• electric worm-gear lifting mechanisms, wherein each of the electric worm-gear lifting mechanisms comprises a worm wheel (47), a worm shaft (49), and a driving motor (48);
• the worm wheel (47) is rotatably mounted inside the vehicle body (1), and the worm wheel (47) is movably sleeved on an outer side of an end of the first rear axle transmission shaft (43);
• the worm shaft (49) is meshed with the worm wheel (47), and the driving motor (48) is connected to the worm shaft (49) and configured to drive the worm wheel (47) to rotate to precisely adjust a height of rear axle and thereby automatically adjust, through being connected to the vehicle-mounted control system, the height of rear axle according to water and land traveling states.
