Abstract

PURPOSE:To improve safety ever so better, by selecting a hydraulic circuit with a swing, in time of car cornering, of the pendulum installed in an undercar riage, and operating a hydraulic mechanism connected to a buffer spring, while constituting a car body so as to be tilted inward. CONSTITUTION:With a swing of a pendulum 23 in time of a car cornering, for example, with a right-hand swing, if it is counterclockwise, a selector valve 11 moves to the left, a barrel part 12 closes an inflow port leading to a left inner chamber 16 of a circulating pipe 21 and a right head part 15 pressed by a spring 14 and a valve seat 10 at the right are tightly closed with each other, thus a right inner chamber 17 is intercepted from a right chamber 19. Therefore, pressure oil passes through the right inner chamber 17 an a circulating pipe 27 and flows into a lower chamber 5 of a left cylinder 2 and an upper chamber of a right cylinder 2, expanding or contracting these left and right cylinders 2 and 2, thus a car body is tilted inward. With this constitution, load balance of wheels at both sides in time of cornering is made so better so that safety is well improved.

Or! 111' Between a circulation pipe that is connected to a hydraulic pump and a cylinder that is fixed to the lower end of the spring in correspondence with the spring, has the spring contained in the upper chamber, has a piston rod in the lower chamber, and has a suspension arm connected to its protruding end. A valve containing a switching valve for the oil passage is provided, and a pendulum provided on the vehicle chassis is linked to the switching valve, and the vibration of the pendulum caused by the centrifugal force acting on the vehicle when cornering operates the switching valve shaft for the oil passage. By converting the oil passage, the height of the outside of the car body is high and the height of the inside of the car body is low when cornering, so that the car body leans inward on its own and prevents the cargo from shifting when cornering. This makes it possible to drive safely.

After flowing into the left ventricle (18) and right ventricle (19)
) and return to the hydraulic tank (25) through the circulation pipe connected to the left chamber (18) and right chamber (19), so the piston rods (6) (6) are not affected by the hydraulic pressure in any way. However, as shown in Figure 2, when cornering counterclockwise, centrifugal force is applied to the car, causing the pendulum (23) to swing outward, or to the right. The switching valve (11) moves to the left, and its body (12) connects to the left inner chamber (16) of the W ring pipe (24).
At the same time, the right head valve 15) pressed by the spring (14) comes into close contact with the right valve seat (10), and the right inner space (17) and the right chamber (19) are shut off. Therefore, the pressure oil flows from the circulation pipe (24) to the right inner chamber (1
7), then passes through the circulation pipe (27) to the royal house (5) of the left cylinder (2) and the right cylinder (2).
