Abstract
The utility model provides an adjustable shock absorber for motor vehicles. The utility model is characterized in that movable wedges which can make auxiliary springs enter or quit an operating state are arranged on one end or both ends of the auxiliary springs of the shock absorber. Thus, springs with corresponding rigidity in the shock absorber take part in work when motor vehicles run on roads with different load, different running speeds and different smoothness. The ride comfort of motor vehicles is largely increased.
Description
The utility model relates to the self-propelled vehicle shock absorber.
The shock absorber that existing self-propelled vehicle is installed and used is all being adorned the single-stage spring.These single-stage springs have fixing rigidity.These shock absorbers can only bear and be not more than the load that adapts with itself spring stiffness, and therefore the spring of the shock absorber of most of vehicles have to be by the design and installation of heavy amount., the vehicle of adorning this shock absorber is during to underloading or empty wagons, and the spring stiffness of shock absorber is still very big, causes its effectiveness in vibration suppression not so well, and is that have even very poor.
The purpose of this utility model is a kind of shock absorber that increases or reduce the number (or group number) of the loaded spring of shock absorber confidential reference items can bigger change be arranged with the load carrying ability of this vehicle time of design.
The utility model is achieved in that (or one a group) main spring and several (or some groups) auxiliary springs is housed in each shock absorber.On the one or both ends of auxiliary spring chock is housed, when vehicle underloading or empty wagons, has only the main spring load in the shock absorber, auxiliary spring is leaving unused.When needs overloading people or weight, by handling chock, make auxiliary spring pressurized all up and down, specifically, make auxiliary spring also the same with main spring, on can be directly by or head on vehicle frame indirectly, can directly or indirectly head on wheel shaft down.Vice versa.The number of auxiliary spring (or group number) is many more, just adapts to the vibration damping requirement of multi-level load carrying ability more.
Owing to adopt such scheme, just can according to the size of load carrying ability regulate the number (or group number) of participating in the spring of load in the shock absorber how much, make shock absorber the favorable damping effect all be arranged in several different load-carrying ranks.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is first embodiment front view of self-propelled vehicle shock absorber that can regulate.
Fig. 2 is second the embodiment front view of self-propelled vehicle shock absorber that can regulate.
Among the figure 1, main spring 2, auxiliary spring 3, chock
In Fig. 1, screw type main spring 1 is arranged in the self-propelled vehicle shock absorber that can regulate, auxiliary spring 2 is being overlapped in the outside of main spring 1, and chock 3 is equipped with in the lower end of auxiliary spring 2.When vehicle underloading or empty wagons, have only main spring 1 load, chock 3 is toward moving down, and pressurized not above the auxiliary spring 2 is in idle state; Chock is up moved to vehicle when heavy duty, make auxiliary spring pressurized about in the of 2, at this moment, auxiliary spring 2 and main spring 1 are together participated in load.
In Fig. 2, in the self-propelled vehicle shock absorber that can regulate, main spring 1 is arranged, auxiliary spring 2 is arranged above the main spring 1, there is chock 3 at the two ends of auxiliary spring 2.During the vehicle empty wagons, chock 3 move to outward auxiliary spring 2 top not till, at this moment do not have pressurized above the auxiliary spring 2, have only main spring 1 to participate in load; When the load of vehicle low middling, the chock 3 at one group of two ends below the auxiliary spring 2 moved to toward in a group of pressing below the auxiliary spring 2 above, at this moment, below the auxiliary spring 2 one group and main spring 1 are together participated in load; When the medium or medium above load of vehicle, chock 3 all moved to toward in two groups of pressing auxiliary spring 2 above, at this moment, together participate in load for two groups of main spring 1 and auxiliary spring 2.
Claims (1)
1, a kind of motor vehicle damper has main spring 1 (group), auxiliary spring several (groups), it is characterized by the auxiliary spring one or both ends and is equipped with and auxiliary spring is entered or the chock of the state of deactivating.
