Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a position measuring device for a change guide plate for a transmission.

(Prior Art) In a general front wheel drive vehicle equipped with a transverse engine, the transmission is mounted on the front part of the vehicle body together with the engine and is away from the shift lever. The change rod of the transmission is connected to the shift lever via a link. Also, since the shift lever is supported by the vehicle body via rubber, when operating the shift lever to shift gears, there is no feeling that it is firmly fixed and held at each shift position, and it feels like a messy feeling. Not only does it deteriorate the ring, but it also tends to cause malfunctions.

Therefore, this type of front-wheel drive vehicle is provided with a change guide. This change guide is composed of a change guide plate fixed to a predetermined position in the clutch housing with a guide groove corresponding to the shift pattern and a selector attached to the change rod, and the tip of the selector is the change guide plate. By engaging with the guide groove of the guide plate and guiding along the guide groove, the operation of the change rod is regulated.

Therefore, the positioning of the mounting position of the change guide plate and the positioning of the selector with respect to the guide groove of the change guide plate are required to be accurate, and conventionally, for example, the positioning jig as disclosed in Japanese Utility Model Publication No. 63-32553 is used. The change guide is positioned using a tool.

However, even when the change guide plate and the selector are assembled by using such a positioning jig, a vehicle with a poor shift feeling may be completed due to a slight deviation of the assembly position, and in particular, the change guide plate may be completed. It has been desired to develop a detection device that can quantitatively determine the quality of the plate mounting position.

(Object of the Invention) Therefore, an object of the present invention is to provide a measuring device capable of easily and quantitatively determining the quality of the assembly position of the change guide plate.

The first jig is attached to the selector at the neutral position in the guide groove of the change guide plate. The second and third jigs are respectively provided with guide groove detecting end portions that are inserted into the guide grooves of the change guide plate and abut against the edges of the guide grooves that are perpendicular to each other.

Further, on the reference frame, a first measuring device for detecting the amount of deviation of the selector by measuring the relative position of the first jig attached to the selector with respect to the reference frame. Is provided, and the guide groove detection end portions are in contact with the predetermined edge portions of the guide groove of the change guide plate on the first jig. Second and third measurements for detecting the amounts of deviation of the guide grooves in the directions perpendicular to each other on the surface of the change guide plate by measuring the relative position of the jig with respect to the first jig. A vessel is provided.

(Effects of the Invention) By using the measuring device according to the present invention, it is possible to easily and quantitatively determine the quality of the assembly of the selector and the change guide plate, and therefore it is possible to prevent the defective product from flowing out. Further, since the measuring device according to the present invention is provided with the first to third measuring devices, it is possible to accurately and quantitatively grasp the factor in the case where the assembly failure occurs in the assembly process, and to immediately mount the device. It is possible to correct the attachment position and make it a good product.
