Abstract
The utility model discloses an absorber for removing foam of shock absorbing oil. The absorber comprises an oil storing barrel, a working cylinder in the oil storing barrel, a piston rod in the working cylinder and a piston connected on the piston rod. A defoaming spring is fixedly arranged on the outer wall of the working cylinder in a sleeved mode. The defoaming spring can scrape the foam in the shock absorbing oil so as to prevent the foam of the shock absorbing oil from entering into the working cylinder, therefore, idle stroke and distortion of the absorber in working are eliminated, abnormal sound of the absorber in operation is eliminated, and comfort and stability of a vehicle are improved.
Description
Technical field
The utility model relates to the shock absorber for vehicle field, particularly a kind of vibration damper of eliminating damping oil foam in the vibration damper work cylinder barrel.
Background technique
Vehicle in motion, the piston rod of vibration damper is constantly made fore and aft motion in work in the cylinder barrel, the damping oil in the work cylinder barrel produces damping force by resistance valves system, comes shock absorbing power, extenuates the vibration in the vehicle running process.Vibration damper in the course of the work, damping oil constantly is pressed into oil storage cylinder and flows into the work cylinder barrel then, when damping oil at a high speed, in high pressure and the frequent flow process, damping oil constantly heats up, damping oil emulsification produces foam, cause damping oil volume increase in the vibration damper, make piston can not get back to original position; When the vibration damper compression damping is increased to the numerical value that can not allow, hysteresis is filled up in the damping oil circulation in the vibration damper work cylinder barrel, vacuum very easily occurs below the piston, makes piston idle running and distortion occur in the work cylinder barrel.In addition, the foam that the emulsification damping oil produces is easy to generate noise and vibration when by the resistance valves in the vibration damper being, causes vibration damper to send abnormal sound in the course of the work.
The model utility content
The technical problems to be solved in the utility model provides a kind of simple in structure, and is easy to assembly, can prevent that the damping oil foam from entering in the work cylinder barrel, eliminates the vibration damper of damping oil foam.
For solving the problems of the technologies described above, the utility model has adopted a kind of vibration damper of eliminating the damping oil foam, comprise work cylinder barrel, the piston rod in the work cylinder barrel in the oil storage cylinder, oil storage cylinder and be connected piston on the piston rod, fixed cover is equipped with a froth breaking spring on the outer wall of described work cylinder barrel.
Described froth breaking spring is cylindrical spring.
Adopt interference fit to be connected between described froth breaking spring and the work cylinder barrel.
The beneficial effect that the utlity model has: this vibration damper arranges a froth breaking spring at the clutch release slave cylinder drum outer wall, when damping oil produces foam and move back and forth between vibration damper oil storage cylinder and work cylinder barrel, the froth breaking spring can scrape off the foam in the damping oil, prevent that the damping oil foam from entering the work cylinder barrel, thereby eliminate idle running and distortion in the vibration damper working procedure, eliminate the abnormal sound in the vibration damper running, improve travelling comfort and the stability of vehicle.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, oil storage cylinder; 2, work cylinder barrel; 3, piston rod; 4, piston; 5, damping oil; 6, froth breaking spring.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Be illustrated in figure 1 as a kind of vibration damper of eliminating the damping oil foam, comprise work cylinder barrel 2, the piston rod 3 in the work cylinder barrel 2 in the oil storage cylinder 1, oil storage cylinder 1 and be connected piston 45 on the piston rod 3, fixed cover is equipped with a froth breaking spring 6 on the outer wall of described work cylinder barrel 2.
The froth breaking spring 6 that this vibration damper adopts is a kind of specification cylindrical springs suitable with work cylinder barrel 2 external diameters.Adopt interference fit to be connected between froth breaking spring 6 and the work cylinder barrel 2, during installation, only need firmly be sleeved on the outer wall of work cylinder barrel 2 with cylindrical spring, and cylindrical spring just can be fixed on the outer wall of work cylinder barrel 2.Adopt interference fit to make damper structure simple between froth breaking spring 6 and the work cylinder barrel 2, do not need to increase other fixedly parts or operations of froth breaking spring 6, and the assembling of froth breaking spring is very convenient.
Claims (3)
