The invention relates to a transverse driving anti-skid parasitic crawler of an electromagnetic-controlled vehicle. The transverse driving anti-skid parasitic crawler is characterized by mainly comprising a transverse anti-skid wheel (1), elastic rubber (2), a connecting hook (3), circumference elastic rubber (4), a power connector (5), a left electric brake (6), a right electric brake (7), a power source (8), a retaining ring (9), annular rubber (10), a motor (11), a rotating shaft (12), a spring (13), a toggle device (14), a motor switch (15), an electromagnet (16), a brake friction lining (17), an anti-skid friction lining (18), an iron block (19), an anti-skid wheel (20) and an accompanying wheel (21). The separating and clutching of the brake friction lining (17) and the anti-skid friction lining (18) are controlled by controlling power on/off status of the electromagnet (16), thereby enabling the transverse driving anti-skid parasitic crawler to prevent the vehicle from slipping under a power off status, and the left-right transverse driving of the vehicle can be realized under a power on status. The transverse driving anti-skid parasitic crawler disclosed by the invention is simple and convenient for mounting, safe and reliable in use.
