Embodiment Construction

[0014] figure 1 A schematic cross-section of a device according to the invention is shown, figure 2 The device is shown from the side.

[0015] The device 100 is assembled in an electric vehicle 1 which is shown in dashed lines and in a simplified manner in the figures. The vehicle 1 comprises at least one wheel 2 equipped with an electric motor 3 . The electric motor 3 includes a rotor 4 mounted on the outer side and an annular stator 5 mounted on the inner side. The type of electric motor 3 may be a brushed or brushless, AC or DC motor.

[0016] The stator 5 of the electric motor is arranged to function as the axis of the wheel 2 so that the stator 5 is fitted to take the load between said wheel 2 and the rest of the structure of the vehicle 1 . A separate wheel hub is therefore not required in the device 100 . The stator 5 is attached to the rest of the structure of the vehicle with attachment means 13 . This attachment means 13 is a known attachment means which enab...

Abstract

The invention relates to a device (100) in an electric vehicle (1), at least one wheel (2) of which is equipped with an electric motor (3). The electric motor (3) includes a rotor (4) fitted on the outside and a stator (5) fitted on the inside. The stator (5) of the electric motor (3) is arranged to act as the axis of the wheel (2) so that the stator (5) is fitted to take the load between said wheel (2) and the rest of the structure of the vehicle (1). Furthermore, the device (100) is equipped with an auxiliary unit (22) comprising a motor control unit (21) and a sensor device (23) arranged to identify the force applied to the vehicle (1) by the operator Force and from this force a sensor signal is generated, the vehicle can be moved by the force of the operator, the control unit (21) is arranged to control the operation of the motor (3) based on the sensor signal.

Description

technical field [0001] The object of the present invention is an arrangement in an electric vehicle, at least one wheel of which is fitted with an electric motor comprising a rotor fitted on the outside and a stator fitted on the inside. [0002] Another object of the present invention is a pallet jack. Background technique [0003] Electric motor structures are known, which are assembled on the wheel to rotate the rotor of the motor on the outer circumference, and the rotor is directly connected to rotate the wheel without a power transmission between the rotor and the wheel. [0004] The problem with known solutions is their complexity. SUMMARY OF THE INVENTION [0005] The idea of ​​the present invention is that the stator of the electric motor acts as the axis of the wheel, thereby allowing the stator to carry the load between said wheel and the rest of the structure of the vehicle. [0006] One advantage is that the structure of the motor, and thus the structure of ...
