Definitions
- the steering mechanism of a vehicle arranged between the steering wheel and the steering box, basically comprises an intermediate shaft typically formed by a male element or steering column and a female element designed to telescopically house the male element.
- the main function of the intermediate axis of the steering column of a motor vehicle is to regulate the position of the steering wheel in depth to adapt to the measures of the driver, as well as acting as a means of safety by allowing collapse in the event of an accident.
- Another function of said axle is to absorb vibrations that may be generated from the wheels and suspension to the steering wheel.
- the intermediate shaft also performs the function of a collapse means so that, in the event of an accident, the male element collapses onto the female element thanks to the arrangement of energy absorbing means.
- a typical configuration of the intermediate shaft consists of a male element and a female element both provided with a polygonal (for example triangular) cross section between which rollers or balls are arranged in contact with the inner faces of the female element and the outer faces of the male element to allow relative sliding between them.
- the main drawback of this type of configuration is that it is costly to have to have rollers or balls along the male and female elements of the intermediate shaft while it is complex to achieve certain tolerances.
- Another drawback of this type of prior art solutions is the high moment of inertia of this type of roller or ball systems. The moment of inertia is initially very high and falls rapidly after impact.
- the invention proposes to considerably simplify the configuration described above in relation to the prior art by providing an intermediate axle of low sliding load of the steering column of motor vehicles with a highly efficient collapse system.
- the proposed intermediate shaft is of the type described, that is to say, formed by a female element adapted to house a male element by sliding inside, both of which have a polygonal cross section, also providing relative sliding means between said male and female elements which, according to the invention, are metal straps.
- as many metal straps will be arranged as faces present the male element and the female element.
- three individual straps will be arranged, one for each face.
- the metal straps are each mounted between said male element and said female element inside cavities formed in a holding cage.
- This cage is immobilized on the male element by means of deformations in the manner of projections on its lateral surface.
- the cage is arranged externally surrounding the male element and is arranged inside the female element, effectively retaining in place the metal straps arranged in their cavities.
- the cage can be made of plastic and be injected directly onto the male element.
- Said straps have an irregular contact surface intended to offer some resistance to relative axial displacement, which will be greater at the first moment of impact to subsequently descend.
- the design variables of the straps are: - the irregularity of their surface; - its thickness; - the material from which they are made; and - the curvature of the sheet with respect to the plane of one of the faces of the male element. These variables are a function of the resistant load that you want to contribute to the intermediate axis of the vehicle's steering column, according to the needs (vehicle model and operating conditions).
- an intermediate shaft as described in accordance with the invention, it is possible to guarantee in a way A low load or force is effective due to the longitudinal movement of the male element with respect to the female element and vice versa, and any type of slack is eliminated without damaging the sliding between the elements, while achieving total efficiency in the transmission of torque at any time. .
- FIG. 1 is a perspective view of an embodiment of an intermediate axle of low sliding load of the steering column of a motor vehicle of according to the invention
- Figure 2 is a perspective view of the female element of the intermediate shaft of the embodiment of Figure 1, which is equipped with the strap clamping cage
- Figure 3 is a perspective view of the male element of the intermediate shaft of the embodiment of Figure 1
- Figure 4 is a perspective view of the straps of the intermediate axis of low load
- Figure 5 is a perspective view of the strap clamping cage
- Figure 6 is a perspective view of the low sliding load intermediate shaft cage of figure 1 with the straps mounted
- the various references that have been used to describe the preferred embodiment of the intermediate shaft of the present invention are listed below: (1) intermediate shaft; (2) female element; (3, 10) universal joint (4) male element; (7) metal strap; (10) cavities of the holding cage; and (11) strapping cage.
- the figures show, by way of non-limiting example, an embodiment of an intermediate axle of low sliding load of the steering column of a motor vehicle, which has been designated as a whole by reference (1).
- the low sliding load intermediate shaft (1) is formed by a female element (2) provided at one end with a universal joint (3).
- the female element (2) is hollow so as to allow a male element (4) to be accommodated inside it by sliding, at the opposite end, also provided with the corresponding universal joint (10).
- the intermediate shaft (1) of the invention is equipped with metal straps (7) for the relative sliding of the female and male elements (2, 4), which offer some resistance to the collapse of the intermediate shaft (1).
- the straps (7) can be seen in Figures 2, 4 and 6 of the drawings.
- the metal straps (7), which are mounted between the male element (4) and the female element (2), are inserted into the cavities (10) of a holding cage (11), as can be seen in figures no. 5 and 6.
- the cage (11) presents a complementary section to the section of the elements (2, 4) of the shaft (1), being mounted externally surrounding the male element (4) and being mounted inside the female element (2).
- the cage (11) is immobilized on the male element (4) by means of projections like projections (not shown) on the lateral surface thereof.
- the cage (11) can be metallic or it can alternatively be plastic injected directly into the male element (4).
- both the male element (4) and the female element (2) have a substantially triangular cross section with blunt corners.
- both elements (2, 4) can have any other type of polygonal section according to the invention.
- This allows the arrangement, in a possible embodiment, of three metal straps (7), as shown in figure 3, retained in position by means of the cage (11) of complementary configuration, as indicated above, and as seen in Figures 2, 5 and 6, to that of said elements (2, 4).
- as many strips (7) will be arranged as faces present the female element (2) and the male element (4) and, consequently, the cage (11).
- the metal strips (7) have an irregular contact surface in order to offer some resistance to the relative axial displacement of both elements (2, 4).
- the irregularity of the surface of the strap (7), its thickness and the material from which it is made will depend on the load resistant that it is wanted to contribute to the intermediate axis (1) of the steering column of the vehicle, according to the needs according to the model and type of vehicle as well as its operating conditions.
- the telescopic arrangement of the intermediate shaft (1) with the configuration of the female and male elements (2, 4) described above allows a correct guiding of the steering column of the vehicle adapting in length according to the type of vehicle and the situations of functioning.
- the polygonal configuration of the intermediate shaft (1) -triangular in the illustrated example- ensures a good torque transmission while the three metal straps (7) immobilized thanks to the arrangement of said clamping cage (11) make it possible for the intermediate shaft (1) perform the collapse function in an efficient way, while having a small resistance to external stress that tends to vary its length in order to adapt to the surrounding conditions.
- the male element (4) collapses on the female element (2) thanks to the aforementioned straps (7) that act as a means of energy absorption.
