Abstract

PROBLEM TO BE SOLVED: To provide a compact and inexpensive shock absorber which has high shock-absorbing performance and is easily mounted.SOLUTION: The shock absorber 12 has a mechanism in which a unit comprising a ball 1 and a spring 2 accommodated in a pipe 3; the units thereof are assembled in parallel or longitudinally in a fore end 11 of a train or an automobile; the units are integrated with each other; and the shock power is structurally dispersed and reduced by the directional change of the return shock, rotation of the ball 1 and contraction of the spring 2.

Description

Conventional shock absorbers are devices that absorb a shock by using a material having a high elastic modulus as a material as a member, and therefore generally have a tendency to lack a shock absorbing performance.

Technology of the shock absorber

Place the spheres or rings that are pressed with springs on both sides in the pipe, with the pipe wall partially cut in half, and partly bulge out the spheres or rings from the hole part. When generated, the spring is compressed and the sphere or ring is rotated, the protruding spheres or rings are aligned in the pipe to increase the strength, and the return impact is perpendicular to the traveling direction of the vehicle or the vehicle body. It is a shock absorber with a mechanism that absorbs shock structurally by changing the direction so that it becomes and keeps the function of the shock absorber by increasing the buffer gain knit in parallel and in series as necessary.

Detailed Description of the Invention

  The billiard-type shock absorber is a shock absorber developed for the purpose of mitigating the impact and protecting the occupant in the event of a collision by installing it at the tip of a high-speed train or car. Therefore, it is necessary to have high shock absorption performance, compactness, easy installation and low cost. As a shock absorber to satisfy these requirements, we have developed a device with the following mechanism and structure. That is, a shock absorber (12) is attached to the front end (11) of the vehicle or the vehicle body, and when the vehicle or the vehicle body collides, it protrudes from the hole (4) of the pipe (3) protruding into the outer wall (13). The ball (5) is subjected to a return impact, and the ball (2) supported by the partition plate (10) adjacent to the ball (5) is pushed and revolved to rotate the spring (2) back. The ball (5) is pressed into the pipe (3) and arranged in a row to increase the strength. At the same time, the impact is dispersed and the return direction of the impact is changed to the direction perpendicular to the traveling direction of the vehicle (5) It is a shock absorber with a structure that reduces the impact on the wheels (7) and rails (8) while reducing the impact back to the cab (6) and a set of ball (5), spring (2) and pipe (3). It is a shock absorber that can be integrated in parallel and in series as a whole. .

Claims (3)

  As a means to relieve or absorb the impact at the time of a vehicle or vehicle collision, a vehicle or vehicle body in a direction perpendicular to the traveling direction of the vehicle body or vehicle is a pipe filled with a ball or ring pressed by springs at both ends. The ball or ring in the front row of the ring or ring arranged in a line from the portion where the ball or ring is drilled in the side wall of the pipe in a part of the pipe placed at the tip of the pipe is half eaten When the vehicle or car body collides, the part receives an impact, rotates the adjacent ball or ring, and compresses the spring pressing from both sides in the horizontal direction to restore the original impact force. This is a shock absorber that reduces the amount of return shock caused by the collision of the vehicle or vehicle body by shifting the direction of the return impact force in the direction perpendicular to the running direction.   Because the portion of the sphere or ring core that comes into frictional contact with the sphere partially protruding from the pipe in advance in the previous section is misaligned with the direction of the sphere or ring core that moves backward due to the repulsion of the collision, It is a shock absorber with a structure that increases the strength of the pipe by reducing the energy of impact by rotating and at the same time arranging the protruding sphere or ring in the pipe side by side.   A sphere or circle that is pressed by a spring supported by a plate wall by frictional contact with the sphere or ring that protrudes and protrudes into a pipe that is cut out by partially drilling a hole in the wall described in the previous section This is a shock absorber in which multiple buffer structures are gathered vertically and horizontally as necessary by arranging a set of ring structures in parallel or arranging similar pipes in tandem.
