Problems solved by technology

[0010] However, since the wheel brakes 141, 142 may have a rather large circumference (for receiving the applied torque), there are space issues

Embodiment Construction

[0032] Figures 1A-1D A braking system for a drive train 50 of a commercial vehicle is shown, in which there are two electric drives 111 , 112 and therefore no differential gear is required.

[0033] In the following, the position description always refers to the force flow along the drive train and not necessarily to the installation in the vehicle.

[0034] Figure 1A A drive train 50 is shown having a first hub 131 , a first transmission 121 , a first vehicle brake 141 and a first electric motor 111 . These parts are used along the first wheel (such as one of the rear wheels; Figure 1A The first drive train of the first transaxle 101 not shown). The first vehicle brake 141 is configured for braking the first hub 131 . In the exemplary embodiment shown, the first vehicle brake 141 is arranged between the first transmission 121 and the first electric motor 111 .

[0035] In the same way, the second transmission 122 , the second vehicle brake 142 and the second electric ...

Abstract

A brake device for utility vehicle having a drivetrain (50) which has at least one electric drive motor (110, 111, 112), at least one transmission (121, 122, 123) and at least one wheel hub (131, 132), comprises a vehicle brake (141, 142) which is arranged downstream of the transmission along the drivetrain (50) when viewed from the at least one wheel hub (131,132).

Description

technical field [0001] The invention relates to a braking device, a drive train, a commercial vehicle and in particular to a high-speed brake for an electric commercial vehicle. Background technique [0002] In conventional commercial vehicles, the drive engine (for example the internal combustion engine) is not mounted on the transaxle. The driving force is transmitted from the drive machine by means of cardan shafts to the differential drive, where it is distributed to the individual hubs or rims. [0003] Furthermore, conventional brakes are often integrated in or on the hub. For this purpose, wheel brakes typically have a rotor (disk or drum) which has the same rotational speed as the wheel to be braked. [0004] For electric vehicles, the drive machine can be integrated in the transaxle. In this case, so-called E-bridges are involved. Furthermore, the drive should often be integrated as far as possible in or on the hub. [0005] Figures 4A to 4C An example of a co...
