Abstract
The utility model discloses a novel traveler assembly for a Macpherson suspension. The novel traveler assembly comprises a damper and a damping spring, wherein the damper comprises an oil storing cylinder; the guiding length of the damper is 65-67 millimeters; and the damping spring is an S-shaped spiral spring of which the two end rings are non-coaxial and are kept in free states. In the technical scheme, the lateral force applied to the traveler assembly caused by running vibration of wheels is counteracted on two aspects; on one aspect, the moving space of a piston rod is increased, and the guiding length of the traveler assembly during working is increased simultaneously, so that the lateral force resistance of the traveler assembly is increased; on the other aspect, the S-shaped spiral spring of which the two end rings are non-coaxial and are kept in free states is adopted, and upper and lower spring holders which adapt to each other are adopted, so that a part of lateral force generated on the traveler assembly by the running vibration of the wheels can be counteracted; and through the improvements on the two aspects, the running smoothness of a vehicle is prevented from being damaged under the influence of the lateral force during working of the traveler assembly.
Description
Technical field
The utility model relates to McPherson Suspension, and specifically, the utility model relates to a kind of novel traveller assembly for McPherson suspension.
Background technology
McPherson suspension is widely used in the car independent suspension with its superior characteristic, but adopt the manned vehicle of McPherson suspension in motion owing to be subjected to structure influence, can make the traveller assembly when crank motion, bear very large side force, this lateral forces is in guide holder and the oil sealing place of shock absorber, make piston rod and oil sealing, guide holder place produce friction force, this friction force can reduce the cushioning performance of shock absorber, directly has influence on the ride comfort of Vehicle Driving Cycle.And, side force is larger, the shock absorber internal friction is larger, the generation of this friction force will directly affect the damping of vibrations of shock absorber, this phenomenon is called the shock absorber clamping stagnation, and this catching phenomenon can cause automobile low speed driving time channel to be difficult for being absorbed by shock absorber and directly passing to vehicle body in the face of the impulsive force of tire, thereby causes the decline of vehicle running smoothness, simultaneously also can cause the traveller assembly to make sound, affect the normal operation of suspension.
Because the existence of above-mentioned phenomenon, can find out by the analysis that vehicle body is acted on the power on the suspension shock-absorber, lateral forces also is subjected to the impact of the guiding length of traveller shock absorber at the friction force of shock absorber, the guiding length of shock absorber is subjected to the control of the oil storage cylinder length of shock absorber, present shock absorber guiding length is generally 38.5mm, guiding length is shorter, amount of deflection when making the crank motion of shock absorber is larger, strengthened the friction coefficient of shock absorber, namely cause side force larger, the shock absorber internal friction is larger.
The utility model content
Technical problem to be solved in the utility model provides a kind of novel traveller assembly for McPherson suspension, destroys the ride comfort of Vehicle Driving Cycle so that the traveller assembly is not subjected to the impact of side force when work.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of novel traveller assembly for McPherson suspension, comprise shock absorber and damping spring, shock absorber comprises oil storage cylinder, the guiding length of described shock absorber is 65～67mm, and described damping spring is that two ends circle disalignment, free state are the coil spring of S shape.
The guiding length of described shock absorber is 66mm.
The length of described oil storage cylinder is 25mm.
The utility model adopts technique scheme, compared with prior art, offset from two aspects that the vibration of travelling causes the side force that is applied on the traveller assembly from wheel, the one, in the activity space that has increased shock absorber base length, also increased the guiding length when the traveller assembly is worked, namely increased the ability of traveller assembly lateral force resistance from this change; The 2nd, adopting two ends circle out-of-alignment free state is the coil spring of S shape, is equipped with the up and down spring holder that adapts again, and can offset a part and travel from wheel and vibrate and to the side force of traveller assembly generation; By the improvement of this two aspect, make traveller assembly when work can not be subjected to the impact of side force and destroy the ride comfort of Vehicle Driving Cycle.
Description of drawings
Fig. 1 is the integral structure scheme drawing of the utility model traveller assembly;
Fig. 2 is the structural representation of the shock absorber of the utility model traveller assembly;
Fig. 3 is the structural representation of the damping spring of the utility model traveller assembly;
Mark among the above-mentioned figure is: 1, shock absorber; 2, damping spring; 3, oil storage cylinder.
The specific embodiment
As depicted in figs. 1 and 2, a kind of novel traveller assembly for McPherson suspension comprises shock absorber 1 and damping spring 2, and shock absorber 1 comprises oil storage cylinder 3.In order to increase the guiding length of shock absorber 1, it is 65～67mm that the guiding length of shock absorber 1 is lengthened, be preferably 66mm, in the activity space that has increased piston rod, also increase like this guiding length when the traveller assembly is worked, namely increased the ability of traveller assembly lateral force resistance from this change.
As shown in Figure 3, damping spring 2 is the coil spring of S shape for two ends circle disalignment, free state, adopting two ends circle out-of-alignment free state is the coil spring of S shape, be equipped with again the up and down spring holder that adapts, can offset that a part is travelled vibration from wheel and side force that the traveller assembly is produced.
In addition, also lengthened to greatest extent the length of oil storage cylinder 3, the optimization length of oil storage cylinder 3 is 25mm.
In sum, by the improvement of this two aspect, make traveller assembly when work can not be subjected to the impact of side force and destroy the ride comfort of Vehicle Driving Cycle.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
