Abstract
The utility model discloses an air-spring flexible air chamber with an adjustable volume. An upper port of a cylinder body is connected with one end of an air pipe in a sealed mode. The other end of the air pipe is communicated with an air-spring main air chamber. An inner cavity of the cylinder body is provided with a rubber air bag and a baffle. An upper port of the rubber air bag is communicated with the air pipe. The bottom surface of the rubber air bag is connected with the baffle capable of moving up and down. The lower part of the baffle is fixedly connected with an actuating mechanism for driving the baffle to move up and down. The actuating mechanism is electrically connected with a control system comprising an ECU (Electrical Conversion Unit). An inflation and deflation system is connected in series between the ECU and one end of the air pipe. According to a working condition signal of a vehicle, the size of the volume of the additional air chamber is realized by deflection deformation of the rubber air bag. The rubber air bag has low density of flexible material, high tensile strength and large percentage of elongation, so that the flexible additional air chamber has good sealing performance and is beneficial for realizing the lightweight of a vehicle body.
Description
Technical field
The utility model belongs to the vehicle air suspension system field, is specifically related to a kind of flexible addition air chamber of air spring suspension, is mainly used in half ACTIVE CONTROL of air suspension, and rigidity, damping and the vehicle body height of suspension are regulated.
Background technique
In the vehicle air suspension system, by regulating rigidity and the damping that the auxiliary chamber size can be regulated air spring suspension, because the outer wall materials of auxiliary chamber generally adopts rigid material, therefore, at present normal adopt manual methods or directly to the auxiliary chamber oil filling method to regulate the auxiliary chamber size, its defective is: the manual methods trivial operations, and directly to auxiliary chamber when oil-filled, because the bad degree of regulation that easily causes of sealability that oil gas mixes is not high.
Summary of the invention
The purpose of this utility model is for the defective that overcomes prior art proposes the adjustable pneumatic spring flexible addition air chamber of a kind of volume, and auxiliary chamber adopts flexible material, the size of effectively regulating auxiliary chamber.
The technical solution adopted in the utility model is: comprise cylinder body, cylinder body tracheae one end that is tightly connected suitable for reading, the tracheae the other end is communicated with pneumatic spring main gas tank, inner chamber of cylinder block is provided with a rubber pneumatic bag and a baffle plate, rubber pneumatic bag connectivity trachea suitable for reading, bottom surface connect baffle plate moving up and down, and fixedly connected one of baffle plate bottom drives its actuator that moves up and down; Actuator is electrically connected the control system that includes ECU, is connected in series inflating-pressure releasing system between ECU and tracheae one end.
The utility model is according to the working condition signal of vehicle, realize the size of auxiliary chamber volume by the deflection deformation of rubber pneumatic bag, the flexible material density of rubber pneumatic bag is lower, tensile strength is high, elongation is big, therefore make the flexible addition air chamber have good sealing property, and help realizing the lightweight of vehicle body.

Embodiment
With reference to Fig. 1-2, the utility model auxiliary chamber comprises cylinder body 2, tracheae 1 one ends that are tightly connected suitable for reading of cylinder body 2, and tracheae 1 the other end is communicated with pneumatic spring main gas tank.A rubber pneumatic bag 3 and a baffle plate 4 are installed in cylinder body 2, the connectivity trachea suitable for reading 1 of rubber pneumatic bag 3, joint at rubber pneumatic bag 3 and tracheae 1 will guarantee good sealing property, connects a baffle plate 4 moving up and down in rubber pneumatic bag 3 bottom surfaces, moves up and down in order to promote rubber pneumatic bag 3.Fixedly connected one of the bottom of baffle plate 4 drives the actuator that baffle plate 4 moves up and down, this actuator can be as shown in Figure 1 linear electric motor 5 or connecting oil pumps 7 by rubber oil sac 11 and form as shown in Figure 2, linear electric motor 5 can be arranged on the bottom of cylinder body 2 inner chambers or be arranged on cylinder body 2 outsides; Rubber oil sac 11 is installed in the bottom of cylinder body 2 inner chambers, and oil pump 7 is arranged at cylinder body 2 outsides, and is oil-filled in rubber oil sac 11 during oil pump 7 work.
Actuator is electrically connected control system, and control system comprises ECU9, sensor 10 and amplification circuit 8 etc., and the linear electric motor 5 of actuator or oil pump 7 are electrically connected control system, serial connection inflating-pressure releasing system 6 between ECU9 and tracheae 1 one ends.Linear electric motor 5 or oil pump 7 all are electrically connected amplification circuit 8, connect ECU9 by amplification circuit 8, ECU9 connects sensor 10 and inflating-pressure releasing system 6 respectively, the switching of ECU9 control inflating-pressure releasing system 6, charge and discharge gas in rubber pneumatic bag 3, mobile or oil pump 7 work of also controlling linear electric motor 5 are oil-filled in rubber oil sac 11.
In the vehicle driving process, sensor 10 constantly detects the driving cycle parameter of vehicle, and detected parameter signal passed to ECU9, ECU9 compares computing according to the signal that receives, needs change pneumatic spring auxiliary chamber volume if operation result shows this moment, then ECU9 sends two path control signal, one tunnel control signal is transferred to inflating-pressure releasing system 6, make it in rubber pneumatic bag 3, inflate or exit, another road control signal is passed to amplification circuit 8, amplification circuit 8 is responsible for signal is amplified processing, to drive actuator's action, the linear electric motor 5 of actuator directly drive baffle plate 4 and move up and down, perhaps the oil pump 7 of actuator oil-filled drive baffle plate 4 in rubber oil sac 11 moves up and down, change the variation of rubber pneumatic bag 3 volumes by the displacement that changes baffle plate 4, promptly change the auxiliary chamber volume, thereby realize control air spring suspension rigidity.
