Embodiment Construction

[0062] Figure 1 schematically depicts, in block diagram form, the main elements necessary to implement the method of the invention. The main steps of the method according to the invention are: measuring at least one physical quantity of the reducer; the measurement result or results constitute information; sending the information to the information processing device; generating control signals for acting on the components that control the operation of the reducer , the control signals are generated by the information processing devices and based on the information processed by these devices; and the control signals are sent to the relevant control components.

[0063] In order to carry out these steps and any auxiliary and / or alternative steps, it is necessary to integrate on a motor vehicle designed to be equipped with a retarder according to the invention a considerable amount of electrical energy (called power) for supplying the retarder devices, control devices and CAN net...

Abstract

The invention relates to a water-cooled electromagnetic retarder, comprising at least one sensor for obtaining information about at least one physical parameter of the retarder, the sensor(s) connected to an information processing device for the generation of control signals based on the processed information, for operating bodies controlling the operation of the retarder.

Description

technical field [0001] The invention relates to a water-cooled electromagnetic retarder, which is designed to be used as an auxiliary braking device or as a durable braking device in a motor vehicle. The invention also relates to a control method of a water-cooled reducer comprising at least one sensor for collecting information on at least one physical quantity of the reducer, and a water-cooled electromagnetic reducer equipped with and enabling the execution of the control method motor vehicle. Background technique [0002] The invention relates to an electromagnetic retarder designed for use in the motor vehicle sector, in particular in the field of industrial vehicles such as heavy-duty trucks, buses and coaches. However, the use of electromagnetic speed reducers is not limited to special types of motor vehicles classified according to their use or weight. On the contrary, the electromagnetic retarder according to the invention, which will be shown later in the descrip...
