Abstract
The utility model discloses an air spring's fastener, including air spring piston (1), nut (2), bolt (3) and air spring supporting beam (4), fasten on air spring supporting beam (4) through bolt (3) and nut (2) air spring piston (1), be equipped with counter bore (7) on air spring supporting beam (4), up be provided with stopper (5) and spring washers (6) in proper order from the bolt head in counter bore (7). The utility model discloses simplify the design of a commercial car air spring supporting beam and frame, reduced the design and the manufacturing cost of whole car, its overall structure is simple simultaneously, has realized the dismouting of swiftly changing, has reduced workman's intensity of labour to reduce the wearing and tearing of connector, prolonged its life.
Description
Technical field
The utility model relates to mechanical equipment technical field, is specifically related to a kind of securing device of air bellow.
Background technology
The air suspension that to have occurred last century with Pneumatic Suspension spring be core, no matter it is much that it has load, vehicle body natural frequency keeps constant substantially, static deflection and load have nothing to do, keep constant feature always, no matter and load is much, all can ensure the corresponding ground Clearance, therefore be widely used on medium-and-large-sized automobile.Usually, air bellow generally by bolted connection at commercial vehicle/comm..vehicle or between bus vehicle frame and air bellow bracing frame.Owing to all there is corresponding geometry to the vehicle frame that air bellow connects or bracing frame, when one or several different air bellow are applied to a commercial vehicle/comm..vehicle, the vehicle frame interface of air bellow support beam and commercial vehicle/comm..vehicle all needs to design targetedly, add the cost of the design and manufacture of car load, simultaneously its installation process also more complicated; In addition, commercial vehicle/comm..vehicle in Long-Time Service process, the road conditions that sometimes work very severe, need in the process of jolting, prevent the movement on air-spring piston and support beam or vehicle frame occurred level direction, current bolt adopts safety washer isotype, along with its wearing and tearing, easily ruptures.
Summary of the invention
The utility model provides a kind of securing device of air bellow, and what the air bellow of different size or structure can be easy is installed on same air bellow support beam or vehicle frame, solves the problem of wearing and tearing between air bellow connector simultaneously.
A kind of air bellow securing device, comprise air-spring piston, nut, bolt and air bellow support beam, air-spring piston is fastened on air bellow support beam by screw bolt and nut, it is characterized in that described air bellow support beam is provided with counterbore, in counterbore, be up provided with limiting stopper and spring washer successively from bolt cap.
Further, groove is provided with in described counterbore; Described limiting stopper is provided with the positive stop lug boss corresponding with groove.
Further, described bolt and limiting stopper are integral type bolt.
After have employed above-mentioned improvement project, simplify the design of Air Springs for Commercial Vehicles support beam and vehicle frame, reduce the design and manufacture cost of car load; Its integral structure is simple simultaneously, achieves the dismounting of high-speeding, reduces the labour intensity of workman, and decrease the wearing and tearing of connector, extend its service life.

Detailed description of the invention
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of air bellow securing device, comprise air-spring piston 1, nut 2, bolt 3 and air bellow support beam 4, air-spring piston 1 is fastened on air bellow support beam 4 by bolt 3 and nut 2, and described air bellow support beam 4 is provided with counterbore 7, is up provided with limiting stopper 5 and spring washer 6 successively in counterbore 7 from bolt cap; Groove 41 is provided with in described counterbore 7; Described limiting stopper 5 is provided with the positive stop lug boss 51 corresponding with groove 41.
As shown in Figure 3 and Figure 4, a kind of air bellow securing device, its another one preferred structure is that described bolt 3 and limiting stopper 5 are integral type bolt 8, and integral type bolt 8 is arranged in the piston of air bellow, air-spring piston 1 and air bellow support beam 4 is bound up by nut 2.By this class formation, decrease the number of parts of this securing device, make installation more efficient and convenient.
Securing device described in the utility model, after being seated, positive stop lug boss 51 on limiting stopper 5 matches with the groove 41 on air bellow support beam 4, limit air bellow support beam 4 and air bellow motion in the horizontal direction, spring washer 6 simultaneously in counterbore 7 can slow down and absorb jolting from road surface, slow down the wearing and tearing caused because of parts relative movement, extend the service life of whole securing device.
The corresponding different setting height(from bottom) of the utility model, can select the spring washer of different size, thus adds the commonality of the utility model to all kinds of air bellow support beam and air-spring piston.
Above-described specific embodiment; technical matters, technical scheme and beneficial effect that the utility model solves are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
