Accompanying drawing 2 is suspension system of the present utility model structural formula schematic diagram when being in equilibrium position;
Accompanying drawing 3 is that suspension system of the present utility model is higher than structural formula schematic diagram during equilibrium position;
Accompanying drawing 4 is A-A partial enlarged drawings of accompanying drawing 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to any restriction of the present utility model.
Embodiment of the present utility model: a kind of suspension system design method of vehicle, the method utilizes rubber air spring to coordinate with altitude valve assembly and realizes adjusting altitude valve assembly position, improve vehicle run smoothness, concrete, by to the rushing of rubber air spring, be vented the change in location promoting altitude valve assembly, and the position of altitude valve assembly countercharge again the rushing of rubber air spring, to be vented thus to reach the position of altitude valve assembly interval in regulation.
The detailed process of the method is: when suspension system is in equilibrium position, and the inlet and outlet gas circuit of rubber air spring is shut by altitude valve assembly and is in closed condition, neither to rubber air spring air inlet, is not also vented; When load weight increases, rubber air spring is depressed in equilibrium position, the air inlet gas circuit of rubber air spring is in open mode, external compression air is by altitude valve air inlet, be vented gas circuit simultaneously and be in closed condition, due to the increase of air pressure, the load carrying capacity of rubber air spring increases and promotion altitude valve assembly moves, close air inlet when altitude valve assembly is elevated to equilibrium position, keep balance; When load weight reduces, rubber air spring upwards raises in equilibrium position, the exhaust gas circuit of rubber air spring is in open mode, rubber air spring compressed air inside is vented, and the gas circuit of air inlet is simultaneously in closed condition, due to the reduction of air pressure, the load carrying capacity of rubber air spring assembly reduces, close exhaust when altitude valve assembly drops to equilibrium position, keep balance, be namely always maintained at certain altitude.
Concrete, the present embodiment comprises rubber air spring, this rubber air spring comprises inner core, urceolus and air bag, urceolus to be enclosed within inner core and to be relative movement, air bag is communicated with urceolus with inner core respectively and forms enclosed cavity, inner core arranges ventilating hole one and this ventilating hole one is communicated with enclosed cavity, vent slot is provided with and this vent slot is communicated with ventilating hole one at inner core inwall, altitude valve assembly is arranged in inner core, wherein this altitude valve assembly comprises the altitude valve being provided with scalable connecting rod and the cylinder be arranged on immediately below altitude valve, telescopic rod stretches out outside inner core, cylinder coordinates with inner core and makes vent slot form closed breather line, cavity one is formed with inner core above cylinder, cylinder is offered ventilating hole two, suction port is provided with in cylinder lower end, urceolus holds out against with the boss being arranged on bottom of cylinder, when suspension system is in equilibrium position, as accompanying drawing 2, ventilating hole one, breather line and ventilating hole two mutual dislocation are also blocked mutually by cylinder and inner core, neither to rubber air spring air inlet, also be not vented, when load weight increases, as accompanying drawing 1, rubber air spring is depressed in equilibrium position, and ventilating hole one, breather line and ventilating hole two is through, forms the air inlet gas circuit of rubber air spring and this gas circuit is opened, external compression air is by altitude valve inlet charge, now rubber air spring is without gas circuit of giving vent to anger, and due to the increase of rubber air spring internal air pressure, urceolus promotes cylinder by boss, close air inlet when altitude valve assembly is elevated to equilibrium position, keep balance, when load weight reduces, as accompanying drawing 3, rubber air spring upwards raises in equilibrium position, ventilating hole one, breather line and cavity one through, give vent to anger gas circuit and this gas circuit that form rubber air spring are opened, now rubber air spring is without air inlet gas circuit, and rubber air spring compressed air inside is vented by altitude valve assembly, due to the reduction of air pressure, the load carrying capacity of rubber air spring assembly reduces, and closes exhaust when altitude valve assembly drops to equilibrium position.
The suspension system of a kind of vehicle constructed by said method, as shown in drawings, comprise rubber air spring 3, this rubber air spring 3 comprises inner core 4, urceolus 5 and air bag 6, urceolus 5 to be enclosed within inner core 4 and to be relative movement, air bag 6 is communicated with urceolus 5 with inner core 4 respectively and forms enclosed cavity, inner core 4 arranges ventilating hole 1 and this ventilating hole 1 is communicated with enclosed cavity, vent slot 8 is provided with and this vent slot 8 is communicated with ventilating hole 1 at inner core 4 inwall, altitude valve assembly 2 is arranged in inner core 4, wherein this altitude valve assembly 2 comprises the altitude valve 10 being provided with scalable connecting rod 9 and the cylinder 11 be arranged on immediately below altitude valve 10, telescopic rod 9 stretches out outside inner core 4, cylinder 11 coordinate with inner core 4 make vent slot 8 formed close breather line, cavity 1 is formed with inner core 4 above cylinder 11, cylinder 11 is offered ventilating hole 2 13, suction port 14 is provided with in cylinder 11 lower end, urceolus 5 and the boss 15 be arranged on bottom cylinder 11 hold out against, vibration damper 1 is provided with at the upper and lower end of altitude valve assembly 2.
