Abstract: A heat exchanger for a motor vehicle, particularly a motorcycle in which a bent cooling element is disposed between a first and second collector tank. The bent cooling element is provided with a longer and a shorter side as well as lateral connecting planes for joining the cooling element to the collector tanks. The collector tanks are made of a material that has substantially lower strength than the material of the cooling element.

Abstract: A transmission gear is composed of two gear elements provided with teeth on their circumference. The gear elements are displaceable coaxially in the circumferential direction and with their teeth offset with respect to one another. The elements are also connected with one another shapewise by at least one connecting member in such fashion that when a meshing gear engages the gear elements, the existing tooth flank play is reduced or eliminated. In this way the connecting member connects the gear elements so that they are nondisplaceable with respect to one another in the circumferential direction and causes the displacement of the gear elements with respect to one another by virtue of its thermal expansion.
