The wheel suspension with transverse force compensation that is used for power actuated vehicle
Technical field
The present invention relates to a kind of wheel suspension with transverse force compensation for power actuated vehicle, relate in particular to the MacPherson type wheel suspension.
Background technology
Because simplicity of design, productive costs are low, the MacPherson type wheel suspension is the wheel suspension of widespread use.The major defect of MacPherson type wheel suspension is the bending moment that acts on bumper, caused by vertical wheel-borne load.The transverse force that acts on bumper typically compensates by being arranged on bumper spring on every side.In this case, the center shaft of spring tilts with respect to the line of centers of bumper usually.This design usually causes coordination problem.
Summary of the invention
The object of the invention is to improve the wheel suspension for power actuated vehicle.
Purpose of the present invention is achieved through the following technical solutions:
A kind of wheel suspension for power actuated vehicle, has the wheel carrier that carries wheel, the lower end is fixedly attached to wheel carrier and upper end are connected to car body in the mode that articulates bumper, be connected to the supporting arm of wheel carrier and car body in the mode that articulates, and the upper end is connected to bumper and lower end are connected to supporting arm in the mode that articulates spring in the mode that articulates.
According to wheel suspension of the present invention, spring is coil spring.
According to wheel suspension of the present invention, spring is connected to supporting arm and/or bumper by spring plate.
According to wheel suspension of the present invention, spring is fixed to the central authorities of supporting arm.
According to wheel suspension of the present invention, bumper is the telescopic damper that its piston rod is connected to wheel carrier, and spring is connected to the cylinder of telescopic damper.
According to wheel suspension of the present invention, the lower junction of the junction of supporting arm and spring is positioned on the straight line.
According to wheel suspension of the present invention, bumper and spring tilt toward each other, and wherein bumper and spring are with respect to the roughly the same angle of vertical line inclination.
According to wheel suspension of the present invention, wheel is wheel flutter.
According to wheel suspension of the present invention, wheel suspension is the MacPherson type wheel suspension.
Spring can be coil spring.Wheel suspension allows the cheap and stable simple coil spring of use cost.By spring is separated with bumper, spring can carry out design and installation with simpler mode and larger degree of freedom.
Spring can be connected to supporting arm and/or bumper by spring plate.One or more spring plates facilitate the fixing of spring, and position and the different spring of permission simple fit of the fastener on it by spring plate for example.
Spring can be fixed to the central authorities of supporting arm.This can be a kind of favourable design according to the vibration behavior.
Bumper can be the telescopic damper that its piston rod is connected to wheel carrier, and spring can be connected on the cylinder of telescopic damper.Telescopic damper is to agree with very much being widely used and durable assembly of concept of the present invention.
The lower junction of the junction of supporting arm and spring can be positioned on the straight line.Supporting arm is connected the mode that articulates and is connected and fix or support by described junction with spring.This simple geometric construction clear and the simple assembling of permission and maintenance.
Bumper and spring can tilt toward each other, and wherein bumper and spring can be with respect to the vertical line roughly the same angles that tilts.That is to say that bumper and spring have respectively positive angle and negative angle with respect to vertical line, wherein angle can be similar or identical.Angle can be in about 5 ° to 20 ° scope.
Wheel can be wheel flutter.Wheel suspension of the present invention be particularly suitable for being generally power actuated vehicle front-wheel turn to or wheel flutter.
Wheel suspension can be the MacPherson type wheel suspension.The wheel suspension simplicity of design of this type, productive costs are low.
Description of drawings
It is following that the present invention is described in detail with reference to Fig. 1:
Fig. 1 represents the scheme drawing according to wheel suspension of the present invention.
Accompanying drawing only is used for explaining the present invention rather than limitation of the present invention.Accompanying drawing and wherein each parts are not necessarily drawn in proportion.Identical Reference numeral represents same or analogous parts.
The specific embodiment
Fig. 1 illustrates for power actuated vehicle, such as the MacPherson type wheel suspension 1 of automobile, truck etc.Nonspring carried mass is comprised of the wheel 2 that comprises tire 3 and wheel rim 4, brake disc 5 and wheel carrier 6.Wheel 2 is installed on the wheel carrier 6.
Wheel carrier 6 is connected to the car body 8 of power actuated vehicle by supporting arm or transverse link 7.Supporting arm is connected to the lower area of wheel carrier 6 in the mode that articulates by the first junction 9.Supporting arm 7 is connected to car body 8 by the second junction 10 in the mode that articulates.It for example is leg-of-mutton aspect that the supporting arm 7 that illustrates has.For example in order to adapt to specific vehicle geometric construction or to obtain specific operating characteristic, other shape also is possible.
Bumper 11 is fixed on the upper area of wheel carrier 6.Telescopic damper has, and fixing (namely not being the mode that articulates) is connected to the piston rod 12 of wheel carrier 6.The cylinder 13 that the bumper 11 of piston or piston rod 12 wherein is installed is fixed or is supported on the car body 8 in the mode that articulates by upper junction 14.Bumper 11 has center shaft 11A, and bumper 11 moves along this axle, i.e. piston 12 turnover cylinders 13.
Bumper 11 and supporting arm 7 are connected to each other by the spring 15 of for example coil spring or support spring form.Spring 15 has center shaft 15A, and spring 15 is compressed and resilience along this axle.
Spring 15 is connected to supporting arm 7 through lower spring junction 17 in the mode that articulates by lower spring plate 16.Lower spring junction 17 can be arranged on the central authorities of supporting arm 7, and is namely identical with the distance at the second junction 10 apart from the first junction 9.Three junctions 9,10 and 17 can be positioned on the straight line.Particularly, can point in parallel with each other perpendicular to the axle at three junctions of figure plane.
Spring 15 is connected to bumper 11 through upper spring junction 19 in the mode that articulates by upper spring plate 18.In the telescopic damper that illustrates, upper spring junction 19 is arranged on the cylinder 13.Upper spring junction 19 can be positioned at any required point of (namely along center shaft 11A) on cylinder 13 the longitudinal direction.Upper spring junction 19 can be arranged in the radial direction (namely perpendicular to the center shaft 11A) apart from any distance of center shaft 11A.
Spring plate 16 and 18 can be used as the parts of spring 15 or as single parts.The geometric construction of spring can be adjusted by length and/or the geometric construction of spring plate 16 and 18.
Bumper 11 and spring 15 tilt with respect to perpendicular line or vertical line.The quiescence of the diagram of Fig. 1 and wheel suspension 1 or normality or reference position are corresponding.This position reaches when the definition load of wheel suspension 1.
Bumper 11 or center shaft 11A on the direction of wheel 2 with respect to vertical line tilt alpha angle.Spring 15 or center shaft 15A on the direction of wheel 2 with respect to vertical line inclination β angle.Two angle α and β, or their size can be identical, or similarly maybe can differ from one another.The scope at angle is about 5 ° to 20 °.
Installing or removing wheel suspension 1 or single parts for example when bumper 11 and/or spring 15, as long as two contact points that will contact with car body 8 are taken into account, they are junction 10 and 14, and they facilitate assembling and the adjustment of wheel suspension 1.Because spring 15 and bumper 11 these two assemblies be provide separately and each form independent unit, spring 15 or bumper 11 can exchange mutually in simple mode.
