Embodiment Construction

[0043] Several embodiments of the present invention are described in detail below with examples and with reference to the drawings.

[0044] In the example shown, the vehicle 200 includes four wheels 100, each wheel being formed as a wheel motor equipped with a traction-brake device. Of course, in other configurations, only two motor wheels can be used, and the other wheels are driven. Independent of motorization, two or four of these wheels can be guided.

[0045] Moreover, the wheels can be connected to the vehicle through a suspension system.

[0046] As already pointed out, the motor wheels to be explained can also be used in vehicles, tricycles, and two-wheeled vehicles with more than four wheels.

[0047] Reference figure 1 , The overall outer width is marked as D2, and the width between the (motor) wheels is marked as D1.

[0048] This involves maximizing the ratio D1 / D2, that is, to provide the maximum available internal space for a limited external width. For transport vehic...

Abstract

A traction-brake device (50) for an electric wheel motor comprising a stator assembly (2), a rotor (3), a brake system (4) with a brake disc (45) rotationally coupled to the rotor , the stator assembly includes a journal support (1), a stator body (21), and a cover (22) defining a cooling chamber (5) of the stator, the journal support including a traction-braking The device (50) is attached to the stationary base (12) of the vehicle, the journal support (1) comprising three axial channels for two fluid ducts (14, 15) and one for the cable channel (16) , the three channels open into the central area (11) of the fixed base.

Description

Technical field [0001] The present invention generally relates to a traction-brake device with electrically driven wheels (this is commonly referred to as a "wheel motor") integrated into a vehicle. More specifically, the present invention relates to a stator assembly for a wheel motor and its associated journal-type support, which is intended to equip a particularly compact traction-braking device housed in a vehicle wheel. [0002] Note here that the wheel may be a guided wheel or a non-guided wheel of the vehicle, and the wheel may also be connected to the vehicle through a suspension system or in a rigid manner. Background technique [0003] The wheel motor according to the present invention can be equipped with, for example, environmentally friendly transportation vehicles, 100% electric utility vehicles, any type of four-wheeled vehicles, 100% electric tricycles, and electric two-wheeled vehicles. The invention can also be used in the case of a hybrid vehicle, one of its axl...
