Embodiment Construction

[0025] The embodiments of the present invention will be further described below in conjunction with the drawings.

[0026] Specific embodiments of the vehicle of the present invention, such as Figure 4 As shown, the vehicle includes a motor. The motor includes a central rotating shaft 11, a junction box 12, a stator assembly 13, a rotor assembly 14, a motor housing 15, a resolver 16 and a speed sensing device. The speed sensing device includes a speed sensor 18 and a center The indexing tooth 19 processed at the end of the rotating shaft 11, the speed sensor 18 corresponds to the position of the indexing tooth 19, and the number of teeth of the indexing tooth 19 is ≥2, which can be specified according to the corresponding technical parameters of the speed sensor 18 (such as the speed pulse per minute The motor housing 15 includes a front cover and a rear cover. A bracket 17 is fixed on the rear cover, and the speed sensor 18 is installed on the bracket 17. When the central rotat...

Abstract

The invention relates to a motor and a vehicle with the motor. The motor comprises a central rotating shaft and a motor casing; and the motor further comprises a speed sensing device, the speed sensing device comprises a speed sensor and indexing teeth that match the speed sensor, the indexing teeth are placed on the central rotating shaft, and the speed sensor is mounted on the motor casing. The speed sensing device is integrated to the motor, the central rotating shaft of the motor is provided with the indexing teeth, the speed sensor is mounted on the motor casing, a heavy indexing gear mechanism is abandoned, the problem that maintenance is inconvenient due to the fact that the speed sensing device is mounted in an axle in the prior art is solved, installation is convenient, the structure is simplified, convenience is provided for arrangement of the whole vehicle, and the integrated degree of components is improved so that the vehicle is lighter.

Description

Technical field [0001] The invention relates to a motor and a vehicle using the motor. Background technique [0002] Currently more commonly used new energy vehicle motors, such as figure 1 As shown, the motor includes a central rotating shaft 1, a junction box 2, a stator assembly 3, a rotor assembly 4, a motor housing 5 and a rotational speed signal measuring device. The rotational speed signal measuring device is a resolver 6, and the motor housing 5 includes a front cover and The back end cover, the resolver 6 is fixed on the back end cover. [0003] Such as figure 2 As shown, the speed sensing device independent of the motor includes a speed sensor 8 and an indexing gear mechanism 9 arranged up and down to match each other. Since the speed pulse signal of the rotating shaft is collected during use, the speed sensing device is generally installed in the axle, the indexing gear mechanism 9 is fixedly connected to the central rotating shaft, and the speed sensor 8 is fixed abov...
