Abstract

A sleeve-shaped coupling member (3) for coupling a camshaft and an ignition distributor shaft (1) in an internal combustion engine is adapted to be disposed coaxially on the ignition distributor shaft (1) for positive connection to the camshaft (2) and retained by a fastening member (6) passing diametrically through the coupling member and the ignition distributor shaft (1), the fastening member (6) being protected against loss by a safety member (7) which embraces the coupling member (3) in a circumferential direction and is an annular body (9) whose diameter has been reduced by deformation. <IMAGE>

Description

SPECIFICATION Improvements in or relating to coupling members for use between a camshaft and an ignition distributor shaft in an internal combustion engine The present invention relates to coupling members for use between a camshaft and an ignition distributor shaft of an internal combustion engine.
One form of such a coupling member has already been described (reference: BOSGH- Technical Information Battery Ignition - 1st Edition, October 1971, Pages 44 and 45), in which a safety member for protecting against loss a fastening member which retains the coupling member on an ignition distributor shaft is a helical spring which is wound in the circumferential direction of the coupling member and which is relatively expensive to manufacture and install.
According to the present invention there is provided a sleeve-shaped coupling member for use between a cam shaft and an ignition distributor shaft in an internal combustion engine, which is adapted to be mounted coaxially on the ignition distributor shaft for positive connection to the camshaft and retained thereon by a fastening pin passing diametrically therethrough and through the ignition distributor shaft, the fastening pin being protected against loss by a safety member which embraces the coupling member in a circumferential direction, and is an annular member whose diameter has been reduced by deformation.
The invention will be further described by way of example with reference to the accompanying drawing, which is an exploded perspective view of one embodiment of the invention.
Referring to the drawing, a shaft 1 is intended to form part of an ignition distributor (not illustrated) of an internal combustion engine (also not illustrated). For the purpose of driving the ignition distributor, the ignition distributor shaft 1 has to be coupled to a camshaft 2 of the internal combustion engine.
For this purpose, a sleeve-like coupling member 3 is mounted coaxially on the ignition distributor shaft 1. The coupling member 3 can be positively connected to the camshaft 2 by dogs which are provided on one of the two end faces of the coupling member 3 for engaging a groove 4 in the end face of the camshaft 2, one of which dogs is shown and is designated 5. The coupling member 3 is rigidly connected to the ignition distributor shaft 1 by a fastening pin 6 which passes diametrically through the coupling member 3 and the ignition distributor shaft 1. To prevent the fastening pin 6 from becoming detached from this structural unit, t is secured against loss by a safety member 7 which embraces the coupling member 3 in a circumferential direction.In order to secure the safety member 7 in position, the coupling member 3 has a circumferential recess 8 for receiving the safety member 7.
To minimise the cost of manufacture and installation of the safety member 7, an annular member 9 is chosen- w.hose diameter is reduced by deformation. For particularly rough-operation, it is proposed that the safety member 7 should be a metal ring made from strip steel and which can be readily brought to its reduced diameter by cold deformation, for example by upsetting by means of a collet embracing the member 9. For less rough operation, a plastics ring of strip polyamide can be used as the safety member, hot deformation then being particularly suitable for reducing the diameter. The safety member 7 is particularly simple to manufacture and install when it is in the form of a tubular plastics member having a cross-linked molecular structure and the tubular member is shrunk onto the coupling member 3 in the region of the recess 8.Advantageously, the tubular member of plastics material is made from polyvinylidene fluoride.

A sleeve-shaped coupling member for use between a cam shaft and an ignition distributor shaft in an internal combustion engine, which is adapted to be mounted coaxially on the ignition distributor shaft for positive connection to the camshaft and retained thereon by a fastening pin passing diametrically therethrough and through the ignition distributor shaft, the fastening pin being protected against loss by a safety member which embraces the coupling member in a circumferential direction, and is an annular member whose diameter has been reduced by deformation.
