Definitions
- the invention relates to a leaf spring assembly for a chassis of a vehicle with a transversely to the longitudinal axis of the vehicle can be arranged transverse leaf spring, the ends of which can be coupled with wheel carriers, being provided on a connectable to a bottom of a structure of the vehicle beam-like cross member a receptacle for a Wattgestlinde issued or Panhardstab recommended ,
- the invention relates to a wheel guidance system of a vehicle with
- Attachment points provided cross member is attached to a bottom of the structure and centrally has a bearing pin on which a swingarm connected to both Wattstangen the Watt linkage device is arranged.
- Vehicle transverse direction extending leaf spring may be provided which supports the structure of the vehicle resiliently with respect to the wheels provided on the wheels.
- Corresponding transverse leaf springs can be used in Rad exitsakuen which as independent suspension, as rigid axles or the one
- Twist beam axles are used on small and medium-sized vehicles
- Front wheel drive used primarily as a rear axle and are one
- transverse leaf springs can in principle also be used for running gears
- Transverse leaf springs which are used as suspension springs in suspension, by a single leaf-shaped spring element or by several in one
- Coil springs consist in lower costs, a smaller space requirement, a self-damping behavior of the leaf spring and possibly one
- the transverse leaf spring is either provided with recordings, via which it is guided on the wheel carriers, or the leaf spring ends are based on recordings which are provided directly on the wheel carriers.
- the transverse leaf spring is usually in a region between the two ends, which is spaced from each other, directly or via an auxiliary frame connected to the structure.
- Watt linkages or Panhardstabeinnchtungen be provided to guide the structure relative to the chassis during a single or rebound movement.
- For this purpose is usually at a bottom of the structure
- Twist-beam axle for a motor vehicle which has two mutually spaced trailing arm with received by these wheel carriers. Furthermore, the torsion-beam axle consists of a twistable tubular part connecting the two trailing arms. The trailing arms are each extended beyond the pipe part and take at their ends guide axes of rotation, over which the torsion beam axle is pivotally guided at the bottom of the structure. A cross-sheet suspension device is connected at each of its two ends via a coupling device with each of the two trailing arms.
- a marriage operations which is designed as Wattgestlindeewed or as Panhardstabewed.
- a leaf spring arrangement for a chassis of a vehicle has a transversely to the longitudinal axis of the vehicle can be arranged transverse leaf spring, the ends of which can be coupled with wheel carriers. Furthermore, a receptacle for a Watt linkage device or a Panhardstab noticed is provided on a connectable to a bottom of a structure of the vehicle beam-like cross member. In this case, according to the invention, the transverse leaf spring is arranged on the cross member.
- both the electronics operations driven and the transverse leaf spring are guided over the cross member at the bottom of the structure.
- the beam-like cross member forms with the respective philosophical evaluations issued, which can be configured as Wattgestlinde worn or a Panhardstab coupled, and the transverse leaf spring a structural unit, which thus has a compact structure and compared to previously known solutions lower number of components.
- the torsion beam axle according to DE 10 2011 116 034 A1 at the height of the wheel center points hinged transverse leaf spring and the hinged at the ends of the trailing arms Watt rods in the vehicle longitudinal direction spaced apart and are separated from each other at the bottom of the body or attached to a subframe. This results in the disadvantages that a larger space is required and a larger number of components is required.
- the transverse leaf spring should be arranged on a side facing away from the bottom of the body surface of the cross member.
- Transverse leaf spring provided receptacle and the cross member to connect with each other.
- the cross member should have two at an angle to each other extending, formed with the same length limbs, which are connected to each other via a parallel to the ground strut, and wherein the transverse leaf spring is disposed on the side facing away from the bottom of the structure surface of the strut.
- the transverse leaf spring can be rigidly attached to the cross member.
- fix bearings on the cross member in which the transverse leaf spring guided longitudinally movable or possibly also limited rotatably guided.
- this may be provided on the side facing away from the bottom of the structure surface of the strut of the cross member.
- the provided on the cross member at least one holding element may be formed such that in this the transverse leaf spring is received via a damping body.
- the cross member and the transverse leaf spring should be made of a fiber-reinforced plastic. There is the possibility that the cross member and the transverse leaf spring are made as a common component of a uniform material.
- a suspension of a vehicle with wheel carriers against which a structure of the vehicle is supported via a transverse leaf spring, and provided with a Watt linkage for transverse guidance of the structure relative to the suspension.
- the Wattgestfite is about one with two end-side
- Attachment points provided bar-like cross member attached to a bottom of the structure, which centrally has a bearing pin. It is hinged to the bearing pin connected to both Wattstangen the Watt linkage rocker or a Panhardstab.
- the leaf spring arrangement should be designed according to one of the claims 1 to 9.
- the suspension may be formed as a the rear axle of the vehicle forming composite beam axle.
- Fig. 1 is a schematic representation in perspective view of a first
- Fig. 2 is a perspective view of a cross member and a
- Fig. 3 shows the assembly of Figure 2, which is supplemented by a Watt linkage
- Fig. 4 is a perspective view of the assembly of Figure 3, wherein in
- Fig. 1 denotes a Rad arrangementssystem, in which two guided via trailing arms 2 and 3 wheel carrier 4 and 5 are connected to each other via a transverse leaf spring 6.
- the two wheel carriers 4 and 5 are guided on a structure of the vehicle or on an intermediate frame by means of wishbones not shown in detail.
- the transverse leaf spring 6 is in a central region via an upwardly facing surface 9 at a side facing away from the bottom of the structure surface 10 a of
- Crossmember 10 attached or guided.
- the cross member 10 has an im
- the Watt linkage device 19 is provided for the transverse guidance of the structure relative to the wheel guidance system 1.
- Transverse leaf spring 6 without swingarm and Wattstangen. It can be seen from FIG. 3 that the transverse leaf spring 6 is fastened to the cross member 10 via spacers 25 and 26. In this illustration, the rocker 20 and the wadding rods 22 and 23 are already arranged on the cross member 10. Finally, according to the figure 4, the rocker 20 is covered by a cover 27.
