Abstract

The utility model discloses a shock absorber with a regulation device. The shock absorber comprises a cylinder body, wherein the cylinder body is internally provided with a piston, the piston is provided with a piston rod stretching out of the cylinder body, the cylinder body is also sleeved with a spring, two axial ends of the spring are respectively connected with the piston rod and the cylinder body, and the peripheral wall of the cylinder body is provided with external threads; and the regulation device comprises an upper spring base, a lower spring base and a locking nut, the upper spring base is arranged on the piston rod, the lower spring base is provided with screw holes which are in fit with the external threads on the cylinder body, the locking nut is in fit with the external threads on the cylinder body and is used for locking the lower spring base, and two ends of the spring are respectively leaned against the upper spring base and the lower spring base. In the shock absorber disclosed by the utility model, the sliding of the lower spring base along an axial direction of the cylinder body can be realized by rotating the lower spring base, the position of the lower spring base can be regulated according to needs, thus the initial length of the spring can be changed, i.e. the hardness regulation of the shock absorber is realized, the spring is not needed to be replaced, and the regulation is convenient.

Description

The vibration damper of band controlling device
Technical field
The utility model relates to a kind of vibration damper, especially a kind of vibration damper with controlling device.
Background technique
Vibration damper is an important component part of automobile suspension system, the concussion when it is mainly used to suppress bounce-back after the spring shock-absorbing and from the impact on road surface.Through uneven road surface the time, though the shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is used for suppressing this spring jump.Vibration damper is too soft, and vehicle body will jump up and down, and vibration damper will bring too big resistance too firmly, hinders the spring proper functioning.In the retrofit process about suspension system, hard vibration damper will be arranged in pairs or groups mutually with hard spring, and the hardness of spring is closely bound up with car weight, and therefore heavier car generally adopts harder vibration damper.
Because vehicle and road conditions is different, vibration damper all needs to carry out corresponding debugging after installation, satisfies the needs when vehicle is actual to be used thus.But traditional shock absorber in order to satisfy the needs of different automobile types and road conditions, is changed spring when producing often, cost height so not only, and be unfavorable for increasing work efficiency.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, and is beneficial to the vibration damper of the band controlling device of debugging.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of vibration damper with controlling device, comprise cylinder body, be provided with piston in the cylinder body, piston is provided with and extends to the outer piston rod of cylinder body, also be arranged with spring on the cylinder body, the axial two ends of spring are respectively free end and fixed end, this free end is connected with piston rod, fixed end is connected with cylinder body, described cylinder body perisporium is provided with outside thread, described controlling device comprises upper spring seat, lower spring cup and locking nut, upper spring seat is installed on the piston rod, lower spring cup be provided with cylinder body on the suitable screw of outside thread, outside thread is suitable and be used for the locking lower spring cup on locking nut and the cylinder body, the two ends of described spring lean with upper spring seat and lower spring cup respectively.
Further be set to: the end away from piston on the described piston rod is provided with outside thread, upper spring seat be provided with piston rod on the suitable screw of outside thread.
Further be set to: described upper spring seat is provided with the last locating slot suitable with spring free end.
Further be set to: described lower spring cup is provided with the following locating slot suitable with spring fixed end.
Further be set to: the end away from piston on the described piston rod is provided with mounting hole, is provided with rubber sleeve in this mounting hole.
The beneficial effects of the utility model are: the spring initial length be spring fixed end to the distance between movable end, and the spring initial length has determined the hardness of vibration damper.By rotating lower spring cup, can realize lower spring cup along Boring mill to slippage, realize being locked to lower spring cup by locking nut then, as required the position of lower spring cup is adjusted, thereby change the initial length of spring, also namely realize the hardness adjustment to vibration damper, need not to change spring, made things convenient for adjustment.Simultaneously, by rotating upper spring seat, can realize upper spring seat along piston rod to slippage, further realize the adjustment to the spring initial length.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, present embodiment comprises cylinder body 1, be provided with piston 2 in the cylinder body 1, piston 2 is provided with the piston rod 3 that extends to outside the cylinder body 1, also is arranged with spring 4 on the cylinder body 1, and the axial two ends of spring 4 are respectively free end 41 and fixed end 42, this free end 41 is connected with piston rod 3, fixed end 42 is connected with cylinder body 1, and the end away from piston 2 on the piston rod 3 is provided with outside thread, is provided with outside thread too on cylinder body 1 perisporium.
The utility model also includes the controlling device 5 for Regulation spring 4 initial lengths, this controlling device 5 comprises upper spring seat 51, lower spring cup 52 and locking nut 53, upper spring seat 51 be provided with piston rod 3 on the suitable screw of outside thread, lower spring cup 52 be provided with cylinder body 1 on the suitable screw of outside thread, outside thread is suitable and be used for locking lower spring cup 52 on locking nut 53 and the cylinder body 1, and the two ends of spring 4 lean with upper spring seat 51 and lower spring cup 52 respectively.Wherein, upper spring seat 51 is provided with the last locating slot 511 suitable with spring 4 movable ends 41, and lower spring cup 52 is provided with the following locating slot 521 suitable with spring 4 fixed ends 42.In addition, vibration damper and vehicle frame is fixing for convenience, so the end away from piston 2 is provided with mounting hole 31 on piston rod 3, is provided with the rubber sleeve (not shown) in this mounting hole 31, and rubber sleeve plays the effect of buffering and noise abatement.
In the utility model, spring 4 initial lengths are the distance that spring 4 fixed ends 42 arrive 41 of movable ends, and spring 4 initial lengths have determined the hardness of vibration damper.By rotating lower spring cup 52, can realize that lower spring cup 52 is along the axial slippage of cylinder body 1, realize being locked to lower spring cup 52 by locking nut 53 then, as required the position of lower spring cup 52 is adjusted, thereby change the initial length of spring 4, also namely realize the hardness adjustment to vibration damper, need not to change spring 4, made things convenient for adjustment.Simultaneously, by rotating upper spring seat 51, can realize that upper spring seat 51 along the axial slippage of piston rod 3, further realizes the adjustment to spring 4 initial lengths.
