Abstract
The utility model discloses a cab air spring, which is characterized in that a buffer shaft sleeve assembly is arranged on the top end of a metal upper cover. A buffer block is arranged at the bottom of the top end of the metal upper cover, the bottom of the metal upper cover is connected with a rubber bag via a metal press ring by means of fastening and pressing, the rubber bag is also connected with a nylon casing by means of fastening and pressing by a metal press ring, a quick connecting plug is disposed on one side of the bottom of the nylon casing, a suspension lug assembly is fixedly connected to the bottom end of the nylon casing, and a drum-type shock absorber is respectively arranged in the metal upper cover, the rubber bag and the nylon casing. The arrangement greatly prolongs service life of the cab air spring without changing usability of the shock absorbers.
Description
Technical field
The utility model relates to a kind of later-model operator's compartment vibration damping parts, definite a kind of novel combined operator's compartment air spring assembly that combines seat damper technique and traditional operator's compartment damper technique of saying so.
Background technology
At present, the operator's compartment of commercial vehicle/comm..vehicle uses coil spring to carry out vibration damping more, and effectiveness in vibration suppression is poor, and the natural frequency of operator's compartment has increased driver fatigue intensity between 3.2Hz～4.0Hz.
Summary of the invention
The purpose of this utility model is to provide a kind of operator's compartment air bellow of new good damping result to remedy former deficiency.
The utility model is provided with buffering axle sleeve assembly on the top of metal top cover, bottom, top at metal top cover is provided with bump rubber, the bottom of metal top cover adopts the mode of withholding to be connected with capsule by the metal pressure ring, capsule also adopts metal crimp latch closure pressure mode to be connected with nylon shell, one side is provided with quick connector in the bottom of nylon shell, the hanger assembly is fixedly connected on the bottom of nylon shell, is provided with cylinder type damper in metal top cover, capsule and nylon shell.
The utility model has carried out compound assembling with rubber air spring and cylinder type damper, so both can guarantee the effectiveness in vibration suppression of air bellow, again the natural frequency of operator's compartment is reduced between 2.2Hz～2.8Hz, improved the level of comfort of chaufeur greatly, and under the situation of the in-use performance that does not change shock absorber, improved the service life of operator's compartment air spring assembly greatly.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is further described.
Fig. 1 is the utility model integral structure scheme drawing.
Among the figure 1, buffering axle sleeve assembly 2, metal top cover 3, bump rubber 4, metal pressure ring 5, cylinder type damper 6, capsule 7, nylon shell 8, quick connector 9, hanger assembly
The specific embodiment
As shown in Figure 1: the utility model is provided with buffering axle sleeve assembly 1 on the top of metal top cover 2, bottom, top at metal top cover 2 is provided with bump rubber 3, the bottom of metal top cover 2 adopts the mode of withholding to be connected with capsule by metal pressure ring 4, capsule 6 also adopts metal crimp latch closure pressure mode to be connected with nylon shell 7, a side is provided with quick connector 8 in the bottom of nylon shell 7, hanger assembly 9 is fixedly connected on the bottom of nylon shell 7, is provided with cylinder type damper 5 in metal top cover 2, capsule 6 and nylon shell 7.
Buffering axle sleeve assembly 1 is mainly used in the operator's compartment entablatrance and is connected; Metal top cover 2 is a metal material, can improve the shock resistance of air bellow, the main effect of bump rubber 3 is to cushion under unexpected situation, 4 interconnect functions of metal pressure ring, capsule is fastened on the metal top cover, the main effect of cylinder type damper 5 is the elasticity of regulating the operator's compartment air spring assembly by its in-to-in damping value, capsule 6 is an elastic element, play buffering vibration and play support and bonded assembly effect, push-in gas-tpe fitting, can connect airline very easily, hanger assembly 9 is mainly used in frame brackets and is connected, and middle rubber bush also plays the effect of buffering.
The utility model does not almost change the structure of portal frame in matching process, utilize original framework of portal frame to install fully, installing space has not only been saved in the compound installation of rubber air spring and cylinder type damper, has also played good damping effect, and convenient the installation; The connecting bridge of this shock absorber all adopts metal material, has increased its shock resistance, can satisfy the come in and go out requirement of various complex road conditions of vehicle.
