FIELD OF INVENTION This invention relates to a common adaptor for instrumented steering wheel and more particularly it relates to fitment of an adaptor for instrumented steering wheel used for steering effort measurement in static and dynamic conditions for steering sub assembly evaluation. BACKGROUND OF INVENTION Steering angle and steering effort measurement is important for steering sub assembly evaluation and also to check the vehicle steering response in various vehicle dynamic conditions. Fitment of the existing instrumented steering wheel on the test vehicle is a very tedious and time consuming job. Also some times, instrumented steering wheel may get fitted above the vehicle steering wheel. This leads to an increase in effective steering heights and does affects the vehicle ergonomics. Also this is an unsafe test condition and may cause accidents. OBJECTS OF INVENTION The main object of this invention is to provide a common adaptor for instrumented steering wheel fitment. Another object of this invention is to provide a simple fitment arrangement. Yet another object of this invention is to save the instrumentation time. SUMMERY OF THE INVENTION According to present invention an adaptor for instrumented steering wheel fitment for steering effort measurement comprising a cylindrical element with upper and lower portions, said upper portion having flanges with holes to connect the instrumented steering wheel, said lower portion having a central hole, a bush with splines located inside said central hole, said lower portion having lateral holes to insert grub screws to lock said bush with lower portion of adaptor. BRIEF DESCRIPTION OF DRAWINGS Figure 1 shows plan view of common adaptor for steering wheel fitment. Figure 2 shows sectional view of common adaptor for steering wheel fitment Figure 3 shows the bush/spacer used to connecting adaptor to the steering column. DETAILED DESCRIPTION OF INVENTION Referring now to the drawings wherein the showings are for the purpose of illustrating a preferred embodiment of the invention only, and not for the purpose of limiting the same. Referring to fig 1, fig 2 and fig 3, the adaptor (1) having cylindrical in shape with a central hole (7) at the lower portion to accommodate a bush (10). The adaptor having two portions, an upper and a lower portion. The upper portion having flanges (2) with holes (4) to connect the instrumented steering wheel. And the bottom part is for accommodating bush (10) and connect to the steering column. In bottom portion (3) below the upper flange (2) , lateral holes (5) are provided to insert grub screws (6). The hole is extending from the outer side of the adaptor to the inner hole (7). The bush (10) located in the hole at lower portion (3) of the adaptor having dents (12) at the centre. The grub screws inserted through the lateral hole (5) at the lower portion (3) of the adaptor and end point of said screws get locked with dents (12) at the centre of the bush. The bush having plurality of vertical splines (11) which are complementary (male and female) to the peripheral splines of the steering column, so that both will interengaged to form a perfect fit. The bush is selected according to the steering column diameter and splines on it. The lower portion of the adaptor with bush fitted to the steering column. The grub screws are inserted and tighten so that the adapter gets locked with steering column. The instrumented steering wheel is placed on top of the adaptor and screw to it. The adaptor can be used for all kind of vehicles. To use with different kinds of vehicle suitable bush should be selected accordingly. The dimension and splines of bush will very according to the steering column of the vehicle on which adaptor to be fitted. The adaptor is easy to mount and on which the instrumented steering wheel can be fitted easily. The time for fitting the instrumented steering wheel can be reduced considerably by adopting such adaptor. The adaptor is very simple in arrangement and compact also. The foregoing description is a specific embodiment of the present invention. It should be appreciated that this embodiment is described for purpose of illustration only, and that numerous alterations and modifications may be practiced by those skilled in the art without departing from the spirit and scope of the invention. It is intended that all such modifications and alterations be included insofar as they come within the scope of the invention as claimed or the equivalents thereof. WE CLAIM 1 The adaptor for instrumented steering wheel fitment for steering effort measurement comprising a cylindrical element with upper and lower portions, said upper portion having flanges with holes to connect the instrumented steering wheel, said lower portion having a central hole, a bush with plurality of splines located inside said central hole, said lower portion having lateral holes to insert grub screws to lock said bush with said lower portion of adaptor. 2 The adaptor for instrumented steering wheel fitment for steering effort measurement as claimed in claim 1 wherein steering column with plurality of splines at its end located inside the bush. 3 The adaptor for instrumented steering wheel fitment for steering effort measurement as claimed in claim2 wherein splines of said bush interengaged with splines of said steering column. 4 The adaptor for instrumented steering wheel fitment for steering effort measurement as claimed in claim 1 wherein instrumented steering wheel located on upper surface of said adaptor. 5 The adaptor for instrumented steering wheel fitment for steering effort measurement as claimed in claim 1 wherein said bush having dents at the centre and locked inside the central hole at the lower portion of said adaptor by inserting said grub screws. 6 The adaptor for instrumented steering wheel fitment for steering effort measurement substantially as herein described with reference to accompanying drawings. ABSTRACT COMMON ADAPTOR FOR INSTRUMENTED STEERING WHEEL FITMENT FOR STEERING EFFORT MEASUREMENT This invention relates to an adaptor for instrumented steering wheel. The proposed adaptor is having a cylindrical in shape with central hole at the lower portion to hold a bush. The upper portion of the adaptor is having flanges to attach the instrumented steering wheel. Lateral holes are provided on the adaptor to fix the bush inside the central hole. The steering column is fixed inside the bush; the splines of bush and steering column are interengaged to form a perfect fit. Fig.l |
