Example Embodiment

[0024] figure 1 A schematic side view of a vehicle 1 is shown, which is equipped with a speed reducer 2 which is connected to and disconnected from a clutch device 4 according to the present invention. The vehicle 1 is also equipped with a gearbox 6 connected to a combustion engine 8 which drives the drive wheels 10 of the vehicle 1 via the gearbox 6 and a conventional transmission mechanism including a propulsion shaft 12 and the like. The driving wheel 10 is equipped with a wheel brake 11. The torque sensor 14 is provided on the combustion engine 8 to detect the torque emitted from the combustion engine 8. The torque sensor 14 is connected to a control device 16 arranged to control the speed reducer 2.

[0025] figure 2 A cross-sectional view of the clutch device 4 for the reducer 2 in a disconnected state according to the first embodiment of the present invention is shown. The clutch device 4 includes a first shaft 18 connected with the rotor 20 of the speed reducer 2 and a...

Abstract

The invention pertains to a clutch device (4) for a retarder (2), comprising a first shaft (18) which is connected to a rotor (20) at the retarder (2), a second shaft (22) which is arranged to engage with a driving source (1), and a first clutch element (54) arranged between the first and second shafts (18, 22). A second clutch element (56; 56') is arranged between the first and the second shafts (18, 22). The invention also pertains to a vehicle (1) comprising such a clutch device (4) and a method for connection of a retarder (2).

Description

technical field [0001] The invention relates to a clutch device for a retarder according to the preamble of patent claim 1 , a vehicle comprising said clutch device according to the preamble of patent claim 15 , and a vehicle according to the preamble of patent claim 16 The connection method used for the reducer. Background technique [0002] The speed reducer is used to brake a driving source such as a vehicle. Usually, the speed reducer is constituted by auxiliary brakes, which complement the wheel brakes of the vehicle. Excessive wear of the wheel brakes is thus avoided. The speed reducer is connected to the vehicle gearbox or propulsion shaft via a transmission. In order to reduce energy losses and thus reduce vehicle fuel consumption, the transmission and the retarder are disconnected from the gearbox or the propulsion shaft when the retarder is disengaged and the vehicle does not need to be braked. When the reducer is not engaged, the reducer shaft stalls. [0003...
