1. Field of the Invention
The present invention relates to inspection tools and more particularly to a vehicle inspection tool that can be used with an L-shaped spanner to inspect a vehicle wheel with a suspension system, discovering abnormalities of component parts of the suspension system.
2. Description of the Related Art
A car suspension system is a connection structure between the car body/car frame and the wheel for absorbing shocks and impact when the car is running over an uneven road surface. This impact will be partially absorbed by the tire of the wheel and majorly absorbed by the suspension system. Except the functions of supporting the car body and absorbing shocks and impact, the suspension system can also keep the tire in positive contact with the road surface, enhancing tire grip, car handling and driving safety, keeping maximum passenger comfort, avoiding damage to the car component parts due to huge shock, and protecting luggage cargo.

However, there is no any inspection tool specifically designed for technicians to inspect a vehicle suspension system. Inspecting a vehicle suspension system is difficult and takes much time. The use of conventional inspection tools cannot rapidly discover any abnormalities to eliminate driving related injury risk.
The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a vehicle inspection tool, which is operable by an L-shaped spanner to oscillate the tire of a vehicle wheel and its suspension system for quick inspection of abnormalities of component parts of the suspension system.
To achieve this and other objects of the present invention, a vehicle inspection tool comprises a tool body comprising opposing first end and second end, an axis line extending between the first end and the second end and an outer surface surrounding the axis line, and a spanner adapter located at each of the opposing first and second ends of the tool body and defining therein a coupling hole for the connection of a driving end of a L-shaped spanner that is readily available in the garage. Thus, the tool body can be biased by the attached L-shaped spanner to oscillate the wheel and its suspension system so that the user can detect any abnormalities of the component parts of the suspension system subject to generated noises and discover the locations of abnormalities and then take the necessary measures at the first time point to eliminate abnormalities at the first time point, reducing driver risk.
Preferably, each spanner adapter can be fixedly fastened to the first end or second end of the tool body by welding.
Preferably, each spanner adapter comprises an embossed pattern on the outer surface thereof. Further, the tool body defines therein an accommodation chamber extending between the opposing first end and second end. Further, each spanner adapter can be tightly press-fitted into one of the opposing first and second ends of the tool body, or alternatively, each spanner adapter can be made having a non-circular outer surface fitting the non-circular cross section of the accommodation chamber of the tool body.

The tool body 10 comprises opposing first end 11 and second end 12, an axis line 13 extending between the first end 11 and the second end 12, and an outer surface 14 surrounding the axis line 13 and fitting the tread of the tire of a vehicle wheel. The outer surface 14 is a surface of full circle. The tool body 10 can be a round tube, defining therein an inner circumference 16 and an accommodation chamber 15 surrounded by the inner circumference 16. Further, the outer surface 14 is a smooth surface, facilitating the operation of the tool body 10.
The spanner adapters 20 are mounted in the accommodation chamber 15 of the tool body 10 and respectively disposed at the first end 11 and the second end 12. Each spanner adapter 20 defines a coupling hole 21 that extends along the direction of the axis line 13 of the tool body 10. The coupling hole 21 is a polygonal hole adapted to receive a driving end 41 of an L-shaped spanner 40, enabling the tool body 10 to be driven to rotate by the L-shaped spanner 40 in the axis line 13. The spanner adapters 20 are welded to the tool body 10 to prevent rotation relative to the tool body 10. Affixing these two spanner adapters 20 to the opposing first end 11 and second end 12 of the tool body 10 enables the vehicle inspection tool to provide an operating end at each of the two opposite ends thereof. However, this arrangement is not a limitation.

In conclusion, the invention provides a vehicle inspection tool, which comprises a tool body and a spanner adapter located at each of two opposite ends of the tool body for the connection of a L-shaped spanner that is readily available in the garage, enabling the tool body to be biased by the L-shaped spanner to oscillate the wheel and its suspension system so that the user can detect any abnormalities of the component parts of the suspension system subject to generated noises and discover the locations of abnormalities and then take the necessary measures to eliminate abnormalities at the first time point, reducing driver risk. Further, the vehicle inspection tool has the advantages of simple structure and ease of operation. Subject to the use of the vehicle inspection tool, a professional technician can greatly shorten the inspection time.
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
