Abstract
A rocker pin attached to a removable support member for a clutch assembly which includes a clutch arm. The plate is removably attached behind the point in the clutch housing where the rocker pin is positioned. A conventional clutch housing can be modified in accordance with the present invention by cutting a window in that portion of the wall of the clutch housing which supports the rocker pin and attaching a support member over the window. Clutch housings and vehicles may be manufactured originally in accordance with the invention by providing a clutch housing wherein the rocker pin is supported by a removable member which mounts to the clutch housing.
Claims29
A clutch housing assembly for the drive mechanism of an automotive vehicle, wherein the drive mechanism comprises a clutch apparatus adapted to be supported inside a clutch housing, a transmission supported inside a transmission case and a pivotally mounted clutch arm extending between the clutch apparatus and a slave cylinder outside the clutch housing, by which clutch arm the drive mechanism is engaged and disengaged in response to movement of the slave cylinder, wherein the transmission case has a mounting flange extending therefrom, the mounting flange having bolt holes therein for attaching the transmission case to a clutch housing by bolts extending therethrough, the assembly comprising:
- a clutch housing adapted to house the clutch apparatus, the clutch housing including a transmission mounting plate with bolt holes therein, the bolt holes being aligned with the bolt holes in the mounting flange of the transmission case;
- wherein the clutch housing defines a first window through which the clutch arm extends;
- a support member having bolt holes therein aligned with the bolt holes in the transmission mounting plate and the mounting flange on the transmission case;
- and
- a rocker pin supported on the support member;
- and
- wherein the shape of the support member and the position of the bolt holes therein permit the support member to be connected to the drive mechanism by bolts which extend through the bolt holes in the support member and through the transmission bolt holes in the transmission case and the clutch housing and so that in the assembled drive mechanism the rocker pin supports the clutch arm for pivotation during operation of the clutch apparatus.
A clutch assembly for the drive mechanism of an automotive vehicle, wherein the drive mechanism comprises a transmission supported inside a transmission case, wherein the transmission is adapted to operate with a clutch apparatus supported inside a clutch housing, wherein the drive mechanism of the automotive vehicle includes slave cylinder for engaging and disengaging the clutch apparatus, wherein the transmission case has a mounting flange extending therefrom, the mounting flange having bolt holes therein for receiving bolts extending therethrough, the assembly comprising:
- a clutch apparatus adapted to operate with the transmission;
- a clutch housing for housing the clutch apparatus, the clutch housing having a transmission mounting plate thereon with bolt holes aligned with the bolt holes in the mounting flange of the transmission case, and wherein the wall of the clutch housing defines a first window;
- a clutch arm extending through the first window of the clutch housing between the slave cylinder of the drive mechanism of the automotive vehicle and the clutch apparatus;
- a support member having bolt holes therein aligned with the bolt holes in the mounting flange of the transmission case and the bolt holes in the transmission mounting plate of the clutch housing;
- and
- a rocker pin supported on the support member and positioned thereon to pivotally support the clutch arm for pivotation during operation of the clutch apparatus, whereby the clutch arm engages and disengages the drive mechanism in response to movement of the slave cylinder.
An automotive vehicle comprising:
- a transmission case including a mounting flange with bolt holes therein;
- a transmission supported inside the transmission case;
- a clutch housing with a first window and with a transmission mounting plate having bolt holes therein aligned with the bolt holes in the transmission case mounting flange;
- a clutch apparatus supported inside the clutch housing and operatively connected to the transmission;
- a slave cylinder outside the clutch housing;
- a clutch arm extending through the first window of the clutch housing and between the clutch apparatus and the slave cylinder;
- a support member having bolt holes therein aligned with the bolt holes in the mounting flange of the transmission case and the bolt holes in the transmission mounting plate of the clutch housing;
- a rocker pin attached to the support member positioned to pivotally support the clutch arm for pivotation during operation of the clutch apparatus, whereby the clutch arm engages and disengages the drive mechanism in response to movement of the slave cylinder;
- bolts extending through the bolt holes on the transmission case mounting flange, the bolt holes on the transmission mounting plate of the clutch housing and the bolt holes in the support member whereby the support member is removably attached to the drive mechanism.
A rocker pin replacement kit for an automotive vehicle having a drive mechanism including a transmission supported inside a transmission case, a clutch apparatus supported inside a clutch housing, the clutch apparatus being operatively connected to the transmission, the clutch housing having a first window in the wall thereof, a slave cylinder, a clutch arm extending through the first window and between the slave cylinder and the clutch apparatus in the clutch housing, the transmission case having a mounting flange extending therefrom, the mounting flange having bolt holes, and the clutch housing having a transmission mounting plate thereon with bolt holes therein aligned with the bolt holes in the transmission case mounting flange, the rocker pin replacement kit comprising:
- a rocker pin comprising a stem with a head on one end;
- a support member attached to the end of the stem opposite the head, the support member including bolt holes therein adapted to be aligned with the bolt holes in the clutch housing transmission mounting plate and the bolt holes in the transmission case mounting flange;
- and
- bolts sized to extend through the bolt holes on the support member, the bolt holes in the transmission mounting flange and the bolt holes in the clutch housing transmission mounting plate, whereby the support member is removably connectable to the drive mechanism so that the rocker pin is positioned to pivotally support the clutch arm so that the clutch apparatus is engaged and disengaged in response to movement of the slave cylinder.
A method for repairing a clutch housing in an automotive vehicle having a drive mechanism including a transmission supported inside a transmission case, a clutch apparatus supported inside a clutch housing, the clutch apparatus being operatively connected to the transmission, the clutch housing having a first window in the wall thereof, the drive mechanism further comprising a slave cylinder, a clutch arm extending through the first window of the clutch housing and between the slave cylinder and the clutch apparatus in the clutch housing, wherein the clutch arm is pivotally supported by a rocker pin mounted on the inside wall of the clutch housing near the window, first the transmission case having a mounting flange extending therefrom, the mounting flange having bolt holes therein, and the clutch housing having a mounting transmission plate thereon with bolt holes therein aligned with the bolt holes in the transmission case mounting flange, wherein the clutch housing wall has been damaged near the rocker pin, the method comprising the steps of:
- removing the original rocker pin, the clutch arm and a portion of the clutch housing wall surrounding the original rocker pin thereby forming a second window in the wall of the clutch housing;
- selecting a replacement rocker pin support member comprising a rocker pin supported on a support member, the rocker pin sized being to support the clutch arm and the support member having bolt holes therein aligned with the bolt holes in the transmission case mounting flange;
- replacing the clutch arm and positioning the replacement rocker pin support member over the second window whereby the rocker pin is held in the position of the original rocker pin;
- and
- connecting the replacement rocker pin support member to the drive mechanism by attaching bolts through the bolt holes in the transmission case mounting flange, the bolt holes in the clutch housing mounting transmission plate and the bolt holes in the replacement rocker pin support member.
