Abstract
The utility model discloses a rear overhang air cushion of an automobile driving cabin, which belongs to an automobile shock absorber. The rear overhang air cushion comprises an air spring and a shock absorber, the air spring comprises a base, an upper cover plate and a leader bag, the base and the upper cover plate are respectively fixedly connected to two ends of the leather bag hermetically and provided with mounting holes, O-shaped seal rings are arranged on walls of the mounting holes, and the shock absorber penetrates through the two mounting holes to be hermetically connected with the air spring. The rear overhang air cushion has the advantages that expansion elasticity coefficient of the air cushion of the driving cabin can be controlled; load bearing capacity can be adjusted according to air pressure; height control can be realized easily; and the air cushion adopting compressed air is light in quality, lower in internal friction and fine in silencing effect.
Description
Technical field
The utility model belongs to automobile shock-absorber, is specifically related to a kind of automobile cab rear overhang air cushion.
Background technique
What the rear overhang of existing operator cabin was used is that metal spring device or hydraulic damper are carried out damping, shortcoming is that rigidity is big, vibration is big, driver and passenger are easy to generate fatigue, vibration damper ruptures easily, damping performance is poor, and the life-span is low, the maintenance more complicated, limit the damping performance and the travelling comfort of operator cabin, can not satisfy the development of existing automobile industry.
Summary of the invention
In order to overcome the above-mentioned technical problem that the prior art field exists, the purpose of this utility model is, a kind of automobile cab rear overhang air cushion is provided, and simple in structure, damping performance is good, can improve the comfort level that automobile cab is taken.
The automobile cab rear overhang air cushion that the utility model provides, it comprises pneumatic spring, vibration damper, described pneumatic spring comprises base, upper cover plate, leather bag, base, upper cover plate are fixed the airtight two ends that are connected leather bag respectively, upper cover plate, base are provided with mounting hole, hole wall is installed is provided with the O RunddichtringO, vibration damper passes described two mounting holes, with airtight connection the between the pneumatic spring.
It also comprises the cover plate hold-down ring, and described cover plate hold-down ring is arranged between leather bag and the upper cover plate, embeds to bind in leather bag.Described upper cover plate is provided with suction port, and suction port is communicated with inside and outside the leather bag, and suction port is provided with the quick-sealing plug.
It also comprises the base hold-down ring, and described base hold-down ring is arranged on leather bag and base bonding place, is sleeved on the leather bag outside, and the base hold-down ring binds and is fixed on the leather bag surface.The described base hold-down ring outside is provided with positive stop lug boss.
It also comprises oil sealing protection pad, cushion pad, and described protection pad, cushion pad are arranged in the pneumatic spring, and suit is fixed on the vibration damper, and protection pad, cushion pad are made by rubber material.
The automobile cab rear overhang air cushion that the utility model provides, its working principle is:
1, automobile cab rear overhang air cushion is that (air pressure 0.3Mpa～0.5Mpa) realizes the nonmetal spring of elastic reaction for the compressibility of utilizing air or nitrogen; Be to form a kind of flexible body by cord (2～4 layers), interior outer rubber layer moulding postcure; After be assembled into assembly; Be commonly called as air bag.
When 2, automobile cab rear overhang air cushion was worked, the leather bag inner chamber charged into pressurized air, forms a pressurized air gas column.Along with the increase of oscillating load amount, the height of air cushion reduces, and cavity volume reduces, and the rigidity of seat air cushion increases, and the effective bearing area of inner chamber air column strengthens, and this moment, the bearing capacity of seat air cushion increased.When the oscillating load amount reduced, the height of seat air cushion raise, and cavity volume increases, and the rigidity of seat air cushion reduces, and the effective bearing area of inner chamber air column reduces, and this moment, the bearing capacity of seat air cushion reduced.
The automobile cab rear overhang air cushion that the utility model provides, its beneficial effect are, may command operator cabin air cushion telescopic resilience coefficient; Can be according to the air pressure adjustment load bearing capacity; The height control that realizes easily; Compressed air quality is light, and interior friction is minimum, acoustic attenuation performance good.
With on the seat of conventional steel shelf structure very large advantage is arranged: 1, can regulate operator cabin rigidity automatically, improve the travelling comfort of operator cabin greatly according to people's body weight and road surface situation; 2, shockproof effect well reduces the driver and produces fatigue because of jolting of road.3, simple in structure, easy for installation, cheap, and operation is safe and reliable.
