## 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.

## Claims

### Claim 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, between which guide sections the endless torque-transmitting member is guided in a direction of travel, wherein the guide device includes two guide device halves that are connected to each other by a plug-in and slide connection arrangement to define a complete torque-transmitting member guide device.

### Claim 2 (depends on 1)

The guide device according to claim 1, wherein the plug-in and slide connection arrangement includes at least one rigid, hook-shaped first connection element, and at least one second connection element having a receiving section and an undercut section for receiving the at least one hook-shaped first connection element.

### Claim 3 (depends on 2)

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 the second connection element.

### Claim 4 (depends on 2)

The guide device according to claim 2, wherein the at least one second connection element is an L-shaped having two interconnected open sections, wherein a first open section defines a receiving section for receiving the first connection element, and a second open section that defines the undercut section to allow sliding movement of the first connection element therewithin.

### Claim 5 (depends on 1)

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.

### Claim 6 (depends on 1)

The guide device according to claim 1, wherein at least one guide half includes at least one detent element, wherein the detent elements of the guide halves are engageable with each other and are effective in a sliding direction of the plug-in and slide connection to latch the guide section halves to each other in a connected condition.

### Claim 7 (depends on 1)

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.

### Claim 8 (depends on 1)

The guide device according to claim 1, wherein the guide section halves of the guide device have identical first and second connections elements, and wherein the connection elements of the first guide section half engage with the connection elements of the second guide section half to facilitate engagement of and to retain engagement of the guide section halves to define a complete guide device.
