Abstract
The invention discloses a dual-airbag spring, and relates to the technical field of machine manufacturing. The dual-airbag spring comprises an upper air bag, a lower air bag, a floating piston and a parallel air chamber fixing rack, wherein the floating piston is positioned between the upper air bag and the lower air bag; the upper edge of the upper air bag and the lower edge of the lower air bag are fixedly connected with the parallel air chamber fixing rack; the lower edge of the upper air bag and the upper edge of the lower air bag are fixedly connected with the floating piston; spring positioning bosses are arranged on middle parts of connection parts of the parallel air chamber fixing rack and the upper edge of the upper air bag as well as the lower edge of the lower air bag and the connection parts of the floating piston and the upper edge of the upper air bag as well as the lower edge of the lower air bag; compression springs sleeve the two opposite spring positioning bosses. The problem that the rigidity is gradually increased during compression, the rigidity is gradually reduced during stretch and the requirements of many suspension devices or vibration reduction devices cannot be met of the air spring in the prior art can be solved.
Description
Technical field
The present invention relates to machinery manufacturing technology field, especially a kind of air spring being applied to suspending apparatus or vibration damping equipment.
Background technique
At present for the spring element of vibration isolation and buffering, majority is helical spring, usually its rigidity is constant, and air spring rigidity can change, there is good buffer shock-absorbing effect, and the volume of air spring is little, cost is low, is widely used in the every field such as medical equipment, automobile, furniture, Weaving device, machine-building; But traditional air spring often compress time rigidity increase gradually, during stretching, rigidity but reduces gradually, so just can not meet the requirement of many suspending apparatus or vibration damping equipment.
Summary of the invention
The object of this invention is to provide a kind of double bolloon spring, air spring rigidity when compressing that it can solve prior art increases gradually, and during stretching, rigidity but reduces gradually, can not meet the problem of many suspending apparatus or vibration damping equipment requirement.
In order to solve the problem, the technical solution used in the present invention is: this double bolloon spring, includes upper gasbag, lower gasbag, is positioned at floating piston between the two and air cavity fixing frame in parallel; The top edge of described upper gasbag, the lower limb of described lower gasbag are fixedly connected with described air cavity fixing frame in parallel, and the lower limb of described upper gasbag, the top edge of described lower gasbag are fixedly connected with described floating piston; The middle part of the middle part of the top edge of described air cavity fixing frame in parallel and described upper gasbag, the lower limb joint of described lower gasbag and the lower limb of described floating piston and described upper gasbag, the top edge joint of described lower gasbag is provided with spring positioning boss, and two relative described spring positioning boss are set with Compress Spring; Described air cavity fixing frame in parallel is connected with fixed pedestal, and described floating piston is connected with needing the device of shock insulation and buffering.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, structure of the present invention is simple, and with low cost, easy for installation, air spring independent compared to existing technology has good spring rate performance, and namely air spring in parallel moves in both direction, can produce larger elastic force, and spring rate also increases gradually; By designing the independent rigidity of different upper gasbags and lower gasbag, multiple different variable integral rigidity can be obtained.
2, the present invention by arranging the mode of Compress Spring in two air bags in parallel, strengthen support or the cushioning effect of double bolloon spring, moment impact load can be cushioned, have that elasticity is high, bearing capacity be large, compact structure, the advantage such as durable, needing there is good application prospect in the large vehicle that work loads is large, the time is long.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Number in the figure is expressed as: 1, floating piston; 2, air cavity fixing frame in parallel; 3, upper gasbag; 4, Compress Spring; 5,6,7,8: spring positioning boss; 9, lower gasbag.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
The double bolloon spring of Fig. 1, includes upper gasbag 3, lower gasbag 9, is positioned at floating piston 1 between the two and air cavity fixing frame 2 in parallel; The top edge of upper gasbag 3, the lower limb of lower gasbag 9 are fixedly connected with air cavity fixing frame 2 in parallel, and the lower limb of upper gasbag 3, the top edge of lower gasbag 9 are fixedly connected with floating piston 1; Air cavity fixing frame 2 in parallel is provided with spring positioning boss 5 with the middle part of the top edge joint of upper gasbag 3, and air cavity fixing frame 2 in parallel is provided with spring positioning boss 8 with the middle part of the lower limb joint of lower gasbag 9; Floating piston 1 is provided with spring positioning boss 6 with the middle part of the lower limb joint of upper gasbag 3, and floating piston 1 is provided with spring positioning boss 7 with the middle part of the top edge joint of lower gasbag 9; Compress Spring 4 is all set with between spring positioning boss 5 and spring positioning boss 6 and between spring positioning boss 7 and spring positioning boss 8; Air cavity fixing frame 2 in parallel is connected with fixed pedestal, and floating piston 1 is connected with needing the device of shock insulation and buffering.The independent rigidity of upper gasbag 3 and lower gasbag 9 changes by variable cross section, different volumes and different inflation pressures etc., can select according to the different-stiffness demand of shock insulation and buffering; The elastic force of two Compress Springs 4 also can be selected according to the different-stiffness demand of shock insulation and buffering, thus can adapt to shock insulation and the buffer requirement of different occasion.
