A straddle type rail transportation system

Abstract

The invention discloses a straddle type rail traffic transportation system. The straddle type rail traffic transportation system structurally comprises an axle, wheels, side frames, a lower center plate and a buffering device, wherein two ends of the axle are mechanically connected with the wheels, the number of the wheels is four, the wheels are mechanically connected with the side frames, and the lower center plate is connected with the side frames. The straddle type rail traffic transportation system has the beneficial effects that outer mechanical force is used for driving and controllinga driving rod to move upwards or downwards, so that a rectangular cavity is controlled to rise or fall, the mechanical matching and separation between a buffer head and an original part at the bottomof a vehicle body are alternated, as the protruding distance between two opposite wall layers on a through groove is gradually reduced, the resistance of the original part entering the through grooveis increased, the vehicle body is made to be decelerated by applying a reverse acting force on the vehicle body, the sliding distance of the vehicle during deceleration parking is reduced, and the effective time of emergency parking braking is shortened, so that the probability of stopping the vehicle on a rail during emergency parking is increased, and the running safety coefficient of the rail vehicle is indirectly improved.

Description

technical field [0001] The invention relates to the field of transportation, in particular to a straddle rail transportation system. Background technique [0002] The opening of rail transportation has greatly improved the efficiency of transportation. The normal operation of rail transportation requires the use of bogies for load bearing, force transmission, buffering and guidance, so as to ensure the normal operation of rail transportation. The current straddle rail transportation system has The following defects: [0003] The existing straddle-type rail transportation equipment achieves the purpose of improving climbing ability, stability and safety by lowering the center of gravity of the carrying unit, and can effectively prevent the power bogie and the vehicle from overturning, but when braking, the bogie The emergency deceleration will cause the car body to always move forward due to inertia, and because the mass of the car body is much greater than that of the bogie...
