Embodiment Construction
[0044] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings:
[0045] like figure 1 Shown: On the turning curve, the track is set super high (the outer rail plane is higher than the inner rail plane), forming a super high inclination angle α, and the centrifugal force F is balanced or partially balanced by the gravitational component G1 formed by the gravity G after tilting.
[0046] In order to further increase the speed of the rail vehicle on the curve, the height of the rail vehicle body on the outside of the curve is increased and the height on the inside of the curve is reduced through technical measures, so that a height difference H is generated on both sides of the vehicle body relative to the rail surface, forming a rail vehicle. With respect to the inclination angle β of the rail surface, the formed inclination angle of the rail vehicle relative to the horizontal plane increases from α to...

The invention relates to a rail vehicle small-amplitude tilting adjusting system and a control method. Comprising an air cylinder, a left air spring, a right air spring, a height adjusting valve, a left height adjusting valve, a first left air valve, a second left air valve, a right height adjusting valve, a first right air valve and a second right air valve. The air cylinder is connected with the left air spring and the right air spring through the height adjusting valve. The left air spring is connected with the air cylinder through a left air valve I and a left heightening valve, and is connected with the air cylinder through a left air valve II and a heightening valve; and the right air spring is connected with the air cylinder through the right air valve I and the right heightening valve, and is connected with the air cylinder through the right air valve II and the heightening valve. The height of the left air spring is controlled through the left height adjusting valve, the height of the right air spring is controlled through the right height adjusting valve, and the height difference and the tilt angle of the air springs on the two sides can be controlled under the condition that a signal monitoring and feedback system is not needed. The rail vehicle tilting and swinging device has the advantages of being simple in structure and low in cost, has good economical efficiency and practicability, and is suitable for transformation and large-area popularization of existing rail vehicles.
Description
technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a small-amplitude tilt adjustment system for rail vehicles and a control method thereof. Background technique [0002] With the continuous improvement of the running speed of the vehicle and the requirements for ride comfort, the existing vehicle suspension system is difficult to meet the safety and comfort requirements when the train passes through the curve at high speed. The pendulum train can make the car body tilt actively before the vehicle reaches the curve, and rely on its own gravity to balance the centrifugal force on the curve, so it can better solve the safety and comfort problems when passing the curve at high speed compared with traditional rail transit vehicles. [0003] Pendulum trains can be divided into natural pendulum and forced pendulum according to the different inclination methods of the body. The natural pendulum is also called passive pendulum. The...
