Abstract
The utility model relates to a damper which comprises an upper and a lower supporting seats, an oil storage cylinder, a piston rod, a helical spring, a spring seat and a sheath. One end of the piston rod is arranged in the inner part of the oil storage cylinder. The helical spring is sheathed at the outer parts of the oil storage cylinder and the piston rod. Two ends of the spring are respectively provided with the sheath and the spring seat. The spring seat is fixedly connected with the oil storage cylinder. The piston rod is connected with the sheath through lock nuts. The utility model is characterized in that the helical spring is composed of an internal helical spring and an external helical spring; the internal helical spring is arranged in the inner part of the external helical spring. The span of the load of the damper in the operating stroke increases, and the damping effect is excellent in the process of light load and heavy load.
Description
Technical field
The utility model relates to a kind of vibration damper, specifically a kind of use vibration damper in motorcycle or electric motor car.
Background technique
Use at present and comprise vibration damper master on electric motor car or the motorcycle, the lower support seat, oil storage cylinder, piston rod, spring, spring seat, sheath, piston rod one end is contained in oil storage cylinder inside, spring also is sleeved on the outside of oil storage cylinder and piston rod, be respectively arranged with sheath and spring seat at the two ends of spring, spring seat and oil storage cylinder are connected, piston rod links to each other by jam nut with sheath, present this vibration damper span of magnitude of load in working stroke is less, effectiveness in vibration suppression is better in zero load or underloading, but effectiveness in vibration suppression just greatly reduces in heavy duty.
The model utility content
The purpose of this utility model is to provide a kind of dual spring vibration damper, and shock-absorbing spring is made up of inside and outside two springs, and the span of this vibration damper magnitude of load in working stroke increases, and when underloading and heavy duty, same good damping effect is arranged.
The utility model is achieved in that
A kind of vibration damper comprises upper and lower supporting base, oil storage cylinder, piston rod, helical spring, spring seat, sheath, piston rod one end is contained in oil storage cylinder inside, helical spring is sleeved on the outside of oil storage cylinder and piston rod, be respectively arranged with sheath and spring seat at the two ends of spring, spring seat and oil storage cylinder are connected, piston rod links to each other by jam nut with sheath, it is characterized in that: described helical spring is made up of internal spiral spring and external spiral spring, and the internal spiral spring is contained in the external spiral spring inner.
The pitch of described external spiral spring is than the pitch greater than the internal spiral spring.
The utility model has adopted the structure of double-helix spring, vibration damper with respect to single spring, the span of magnitude of load increases in working stroke, makes no matter electric motor car or motorcycle are that underloading or heavily loaded vibration damper can both play good effectiveness in vibration suppression, improves the travelling comfort of vehicle.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an internal structure schematic representation of the present utility model.
Embodiment
Shown in Fig. 1-2, a kind of vibration damper comprises upper and lower supporting base 1,2, oil storage cylinder 3, piston rod 4, helical spring, spring seat 5, sheath 6, piston rod 4 one ends are contained in oil storage cylinder 3 inside, helical spring is sleeved on the outside of oil storage cylinder 3 and piston rod 4, be respectively arranged with sheath 6 and spring seat 5 at helical spring two ends, spring seat 5 is connected with oil storage cylinder 3, piston rod 4 links to each other by jam nut 7 with sheath 6, described helical spring is made up of internal spiral spring 81 and external spiral spring 82, and internal spiral spring 81 is contained in external spiral spring 82 inside.
The vibration damper of employing dual rotary spring has wideer load span with respect to the vibration damper of single spring, and the pitch of external spiral spring 82 is than the pitch greater than internal spiral spring 81, like this be arranged on the vehicle underloading time external spiral spring since the pitch broad in the few situation of compressive deformation, the elastic force that supports is not strong, therefore vibration damper can not make vibration damper keep away and shake and seems harder because of dual spring is installed when underloading, make vehicle that higher travelling comfort be arranged when underloading, and when heavy duty, the spring of vibration damper is further compressed, make the external spiral spring produce bigger reaction force and make vehicle when heavy duty, still have travelling comfort preferably, thereby realize that vibration damper increases the purpose of load span.
The utility model can be by the position of spring seat on oil storage cylinder in addition, and the hardness of regulating vibration damper is to adapt to the demand of different crowd better.
Claims (2)
1, a kind of vibration damper comprises upper and lower supporting base, oil storage cylinder, piston rod, helical spring, spring seat, sheath, piston rod one end is contained in oil storage cylinder inside, helical spring is sleeved on the outside of oil storage cylinder and piston rod, be respectively arranged with sheath and spring seat at the two ends of spring, spring seat and oil storage cylinder are connected, piston rod links to each other by jam nut with sheath, it is characterized in that: described helical spring is made up of internal spiral spring and external spiral spring, and the internal spiral spring is contained in the external spiral spring inner.
2, a kind of vibration damper as claimed in claim 1 is characterized in that: the pitch of described external spiral spring is than the pitch greater than the internal spiral spring.
