Generally, it should not be less than.2000m, and it should not be less than 1000m in difficult areas. 4.2 The main technical performance of the vehicle 4.2.1 The car body shall adopt a light overall load-bearing structure, and the maximum longitudinal static pressure test load shall not be less than 350kN. 4.2.2 The vehicle bogie structure should be composed of frame, running wheels, horizontal guide wheels, horizontal stabilizer wheels and transmission devices, and its structure and size should match the track beam. The pressure of the horizontal guide wheels and horizontal stabilizer wheels on the track beam Should be adjustable. The relevant components of the bogie shall be within the allowable wear limit, so that the train can run safely and smoothly at the highest speed. 4.2.3 The bogie of the vehicle can be double-axle or single-axle bogie, and the air spring without bolster should be used. 4.2.4 Each running wheel and horizontal wheel should have an independent tire pressure monitoring and air loss alarm device, and should be equipped with an auxiliary running device. 4.2.5 Electric braking and friction braking of trains should be able to coordinate and cooperate; common braking should use electric braking first, and should have impact rate limit; when electric braking is insufficient, friction braking should be based on the total braking force. It is required to supplement the insufficient braking force, and the electric braking and friction braking should be switched smoothly. 4.2.6 In addition to meeting the requirements for normal operation, the traction power configuration of the train should also meet the following requirements for faulty operation and rescue of faulty trains. 1.When the train loses 1/4 of the power, it should be able to start on the largest ramp on the main line under the overcrowded state, and can run to the end, and return to the vehicle base after clearing passengers; 2 When the train loses 1/2 of the power, it should be able to start on the largest ramp on the main line and run to the adjacent station under the condition of overcrowding; 3 A column of unloaded rescue vehicles shall... ......
