Abstract

A guide device for guiding an endless torque-transmitting member of a belt-driven, conical-pulley transmission. The device includes an outer guide section, and an inner guide section that is spaced from the outer guide section and between which guide sections the endless torque-transmitting member is guidable in a direction of travel of that member. The device is formed from two halves that are connected to each other by a plug-in and slide connection arrangement, in order to improve the guide device structurally, functionally, and from a producibility standpoint.

First claim

What is claimed is:

1. A guide device for guiding an endless torque-transmitting member of a belt-driven, conical-pulley transmission, said guide device comprising:
a first guide section, and
a second guide section spaced from the first guide section and between which guide sections the endless torque-transmitting member is guided in a direction of travel,
wherein the guide device includes first and second guide device halves that are connected to each other by a plug-in and slide connection arrangement, wherein the first and second guide device halves each include respective pairs of connection surfaces that each include respective connection elements arranged so that the guide device halves are assembled by initially moving the guide device halves toward each other to bring into contact their respective opposed connection surfaces and to engage respective opposed connection elements on the respective connection surfaces, and after contact of the respective connection surfaces the guide device halves are thereafter moved relative to each other in the direction of travel of the endless torque-transmitting member a predetermined distance to define a complete and assembled torque-transmitting member guide device.

2. The guide device according to claim 1 , wherein the plug-in and slide connection arrangement includes as a connection element at least one rigid, hook-shaped first connection element that extends outwardly from a respective guide device half connection surface, and wherein the plug-in and slide connection arrangement includes as a connection element at least one second connection element formed in a respective guide device half connection surface and defined by an open receiving section for receiving a hook-shaped first connection element, and an open undercut section for allowing the hook-shaped first connection element to move within the undercut section as the guide device halves are moved relative to each other in the direction of travel of the endless torque-transmitting means.

3. The guide device according to claim 2 , wherein the at least one first connection element is a rigid, L-shaped hook that is engageable with a respective second connection element.

4. The guide device according to claim 2 , wherein the at least one second connection element is an L-shaped opening having two interconnected open sections, wherein a first open section defines a receiving section for receiving a respective first connection element, and includes a second open section that defines the undercut section to allow sliding movement of a respective first connection element therewithin in the direction of travel of the endless torque-transmitting means.

5. The guide device according to claim 1 , wherein each of the guide section halves has at least one first connection element and at least one second connection element.

6. The guide device according to claim 1 , wherein the guide section halves each include at least one detent element, wherein the detent elements of the guide section halves are engageable with each other and are effective in a sliding direction of the plug-in and slide connection elements relative to each other in the direction of travel of the endless torque-transmitting means to latch the guide section halves to each other in a connected condition.

7. The guide device according to claim 1 , wherein each of the guide section halves includes at least one detent element that corresponds in shape with at least one detent element of the other guide section half, and wherein the detent elements are engageable with each other to connect the guide section halves and to retain the guide section halves in connected condition.

8. The guide device according to claim 1 , wherein the guide device halves of the guide device each include identical first and second connection elements, and wherein respective first connection elements of the first guide section half engage with respective second connection elements of the second guide section half, and respective second connection elements of the first guide section half engage with respective first connection elements of the second guide section half to facilitate engagement of and to retain engagement of the guide section halves when assembled to define a complete guide device.
