Definitions

  • the invention relates to transport engineering, in particular, to shock absorbing suspension devices and can be used in front and rear shock absorbers of cars and other equipment.
  • shock absorbers for example, the shock absorber of the car BAZ-2108 (see. Car BAZ-2108 "Sputnik”: Device and repair / VAVershigora, A.P. Ipatov and others G. Transport 1987, p. 82-83), which contains a cylinder with a rod on which a spring-loaded piston with a nut of the recoil valve is installed.
  • a compression valve is located at the bottom of the cylinder, and a recoil stroke hydraulic buffer at the top.
  • the specified set of design features does not allow to eliminate the disadvantages inherent in most known designs, namely: - low operational reliability when driving on road surfaces with varying degrees of roughness;
  • a shock absorber with variable hydraulic resistance (Ukrainian patent Ne 61670, publ. In November 17, 2003), which contains a working cylinder with metering holes in the lower part, an external reservoir for the working fluid, a rod that passes through the guide sleeve, and a spring-loaded working piston with metering holes and check valves, a metering device is installed on the bottom of the stem , which consists of a hollow body with metering holes with a spring-loaded control cylinder located in it and a control rod attached to the lower part of the body and mounted axially displacement inside the control cylinder, and in the lower part of the rod a cavity is made connected to the rod cavity of the working cylinder and the body cavity.
  • the objective of the invention is to increase the efficiency and reliability of the shock absorber when driving on road surfaces with varying degrees of bumps at medium and high speeds.
  • a self-adjusting shock absorber with a valve for limiting the resistance force which contains a working cylinder with metering holes in the lower part, an external reservoir for the working fluid, a rod with a cavity that is connected to the rod cavity a working cylinder and a body cavity that passes through the guide sleeve, and a spring-loaded working piston with metering holes and check valves, and a metering device located on the lower part of the rod, according to the invention, contains a valve to limit the increase in the resistance force of the shock absorber and a spring-loaded part made with the possibility of displacement under the influence of the pressure difference between the cavities of the shock absorber.
  • the shock absorber contains an external reservoir 25 with a working cylinder 1 inside which a rod 2 is located, on which a piston 6 with a spring-loaded spring 19 is fixed, a compression valve 7 for passage of the working fluid in one direction relative to the piston 6, and a metering device, which consists of a metering body 9, the metering piston 10 and the metering rod 11, designed to regulate the capacity in the other direction relative to the piston 6, depending on the pressure difference in the rod 23 and rodless 24 cavities of the shock absorber during its operation.
  • the shock absorber contains a valve 22, designed to limit the increase in force that occurs during operation of the metering device, as well as a compression valve 14.
  • the rod 23 cavity of the working cylinder 1 is separated from the external reservoir 25 by a housing 4 with a guide sleeve 3 and a seal 5 for the rod 2, rodless 23 the cavity is separated from the external tank 25 by a device with a throughput, and consists of a valve 14, a spring-loaded spring 18 and a throttle hole 16. In the rod 2 there is a throttle hole 15.
  • BEST MODE FOR CARRYING OUT THE INVENTION The proposed device works as follows: When the shock absorber rod enters, the spring 17 returns the piston of the dispenser 10 to its initial position.
  • the piston of the throttle 10 drops as much as possible onto the rod of the dispenser 11 and significantly reduces the cross-section between them, which maximizes the resistance of the shock absorber, while part of the liquid through the hole 15, the piston of the dispenser 10, the cross section between it and the rod of the dispenser 11, passes through the hole 12 into rodless 24 cavity shock absorber.
  • Part of the fluid through the hole 15 passes inside the housing 20 of the valve 22, overcomes the force of the spring 21, opens the valve 22 and passes into the rodless cavity 24, which limits the maximum resistance force of the shock absorber.

Abstract

L'invention concerne un amortisseur autoregulé muni de soupapes de limitation de l'effort de résistance, qui appartient au domaine des constructions mécaniques de transport et notamment des dispositifs de suspension qui s'utilisent pour l'amortissement et peuvent s'employer dans les amortisseurs avant ou arrière d'automobiles ou d'autres équipements. L'invention vise à augmenter l'efficacité et la fiabilité de fonctionnement des amortisseurs lors du déplacement du véhicule automobile sur un revêtement routier présentant des irrégularités à des degrés différents, à vitesses moyennes à élevées. Selon l'invention, un amortisseur autoregulé muni d'une soupape de limitation de l'effort de résistance contient un maître cylindre qui comporte des orifices de dosage dans la partie tige du maître cylindre et la cavité du corps, qui passe à travers la douille de direction et le corps de travail prétensionné par ressort avec des orifices de dosage et une soupape de circulation ainsi qu'un dispositif de dosage disposé dans la partie inférieure de la tige; il comprend une soupape de limitation de l'effort de résistance de l'amortisseur et une pièce prétensionnée par ressort, fabriquée de manière à pouvoir se décaler sous l'effet de la différence de pression entre les cavités de l'amortisseur.
