The invention relates to a hub motor for a tunnel tractor vehicle. The hub motor is characterized by comprising a casing, a stator fixing frame, a rotor, a stator, a first sun wheel, a first planet wheel, a second sun wheel, a second planet wheel, planet wheel supporting shafts and a main shaft, wherein the first planet wheel and the second planet wheel are integrally keyed in a jointing manner through a planet wheel connecting spline housing; the first planet wheel and the first sun wheel are in the external tooth meshing; the second sun wheel is supported on the main shaft through second sun wheel supporting bearings; an unlocking mechanism is connected to a power output connecting disk. The invention further discloses a tunnel tractor vehicle wheel. The hub motor for the tunnel tractor vehicle is fixedly connected with a tyre fixing steel ring, and the tyre fixing steel ring and a solid tyre are fastened to form a whole wheel. The hub motor and the tunnel tractor vehicle wheel have the benefits that the hub motor integrates the functions of a motor, a decelerator, a clutch and a brake in a hub, so that a space is saved for the tractor vehicle, and the functions that the tractor vehicle can be automatically self-locked when the tractor vehicle is not electrified so as to prevent the vehicle slipping, and the tractor vehicle can be automatically self-unlocked and transformed into the operating state after electrifying are realized.
Description
technical field [0001] The invention belongs to a tractor and a motor, in particular to a hub motor for a tunnel tractor and a wheel of the tunnel tractor. Background technique [0002] Existing tractors can be divided into two categories: internal combustion engine drive and electric motor drive according to different power sources. Electric traction is preferred in environments with poor air circulation such as tunnels. The basic functions that the tractor needs to have include forward and backward functions, braking functions, and sliding functions when towing. [0003] Application number: 201420591822.7 discloses a tractor, including a car body, the lower end of the car body is wheels, the wheels include wheels on both sides of the front row and wheels on both sides of the rear row, a total of four wheels, the main points of the structure are arranged inside the rear end of the car body The battery, the car body is provided with a battery power indicator, a power supply...
