Abstract

Device for truck cab suspension comprising a forward cab suspension which itself comprises a carrier frame (1) fastened to the cab and is so arranged that on each long side of the truck (3) it is close to a stabiliser (4), and that via articulation means (6) it allows forward tilting of the cab by at least one tilt cylinder (11), whereby the cab suspension comprises cab spring means (13, 14) adapted to acting between the truck chassis (2) and said carrier frame. The device is distinguished particularly by the fact that the carrier frame (1) is supported for pivoting relative to the forward lower portion (7) of each of two endpieces (8) which form part of the carrier frame and are each connected to their respective stabiliser (4) which is situated rearward from said forward lower portion and is supported by the truck chassis (2)

Description

DEVICE FOR TRUCK CAB SUSPENSION
Background
1. Technical field
The present invention relates to a device for cab suspension for trucks according to the introductory portion of the attached claim 1.
2. Description of state of the art
Devices for the purpose indicated above are previously known. Such known arrangements are designed inter alia in such a way that the cab stabilisers' torsion springs and hence the stabiliser set-up are positioned at the front of the cab and constitute together with tilt cylinders and cab springing a protruding and relatively bulky configuration.
The object of the present invention is to provide a device for cab suspension which is substantially more compact than what is available in the state of the art and which thereby frees space for, for example, crash zone and radiator.
Summary of the invention
The above object is achieved by what is specified in the attached claim 1.
Further advantages are afforded by what is indicated in the dependent claims.
Brief description of the drawings
The invention is described below in more detail with reference to embodiments and the attached drawings, in which - Fig. 1 depicts schematically a perspective view of, inter alia, a first embodiment of a track cab suspension system according to the invention as seen obliquely from the rear and from above on the left side of the track, the depiction being of a state corresponding to when the cab is retracted,
- Fig. 2 depicts schematically a system according to Fig. 1 as seen when looking at the left side of the vehicle in Fig. 1 and in a state corresponding to when the cab is tilted upwards and forwards, and
- Fig. 3 depicts schematically the same as Fig. 2 but in a state corresponding to when the cab is retracted.
Detailed description of preferred embodiments
In Fig. 1, ref. 1 denotes a carrier frame fastened to the cab and forming part of a forward cab suspension, although the cab itself, inter alia, is not depicted in the drawings. The carrier frame is so arranged that at each long side 2 of a truck 3 it is close to a stabiliser 4 which is preferably of torsion type and arranged with its pivot spindle 5 transverse to the longitudinal direction of the truck.
According to the version depicted, the carrier frame 1 is adapted to being supported by articulation means 6 relative to the forward lower portion 7 of each of two endpieces 8 which form part of the carrier frame and are each situated on their respective long side 2 of the truck, which endpieces are connected to one another rearward, as seen in the longitudinal direction of the truck, from said forward lower portion 7, and by stabilisers supported by the truck chassis, as depicted in the drawings.
Said forward lower portion is preferably connected to the stabiliser by connection means 9 running from said portion, e.g. an arm 9', which is adapted to transmitting a rotary movement to undepicted torsion elements of the stabiliser. According to preferred embodiments, there is a shock absorber 10 acting between said forward lower portion and the truck chassis.
Ref. 11 denotes a tilt cylinder which is supported for pivoting close to a stabiliser and is adapted to acting upon one of said endpieces for tilting of the cab, as depicted in Figs. 2 and 3. According to the version depicted, the cylinder is adapted to pivoting by means of an external articulation 12 about the stabiliser's torsion elements.
A version whereby at least one tilt cylinder is supported for pivoting relative to the truck's engine or frame and is adapted to acting upon the cab floor for tilting of the cab is not depicted.
According to versions preferred in certain cases, a tilt cylinder is arranged in combination with cab spring means 13. According to the version depicted in the drawings, the cab spring means 13 comprises an air cylinder 14 arranged about the tilt cylinder, which air spring is extensible, as depicted in Fig. 2.
The function of the device according to the invention is perhaps substantially indicated above. The set-up for stabilisers and tilt cylinders is thus rearward from, behind, the pivotable support for the carrier frame, whereby the loadbearing portions of the arrangement which are to be supported by the truck chassis can be moved in from the front of the truck, thereby freeing space for, for example, crash zone and radiator. The result, particularly if stabilisers, tilt cylinders and cab spring means are combined in an in principle common set-up, is a very compact and, as regards space, effective arrangement.
The invention is described above in relation to embodiment examples and preferred embodiments. Further embodiments, and minor modifications and additions, are of course conceivable without thereby departing from the fundamental concept of the invention. According to the version depicted, the endpieces 8 have a substantially triangular latticework configuration. Other configurations, e.g. lamelliform, are conceivable.
It is also conceivable, preferably with maintenance of a largely common set-up, for tilt cylinders and cab spring means to be more clearly separated.
The invention is thus not to be regarded as limited to the embodiments indicated above but may be varied within its scope indicated by the attached claims.

Claims
