Abstract
The utility model relates to a rear wheel mechanism for electric vehicles. The rear wheel mechanism comprises a motor assembly, a main shaft, and a hub, wherein the front end of the main shaft is in drive connection with the motor assembly, the middle of the hub is connected to the rear middle of the main shaft through a bearing, and the hub is locked to the main shaft through a hub connecting disc. The rear wheel mechanism is simple in structure and is integrally in a through shaft structure convenient to disassemble. The main shaft is connected with the hub, so that load borne by a rear wheel is directly used for the main shaft, the motor bears no load, and accordingly the service life of the rear wheel mechanism is prolonged; meanwhile, the through shaft structure allows a high-speed motor 3.5kr/min in speed to be applicable to the motor assembly, so that compared with the existing electric vehicle using only the 0.4kr/min low-speed motor, the electric vehicle using the motor assembly is fast to start, high in gradeability (capable of climbing a 20-degree slope, while the existing vehicle can only climb the 9-degree slope), low in climbing discharge and long in cruising distance; in addition, the high-speed motor is used, fewer expensive materials are used, and the cost can be reduced by more than 10%.
Description
Technical field
The utility model relates to a kind of rear wheels of electric vehicle mechanism.
Background technology
Back wheel driving gear is the major impetus source of battery-driven car, the reasonableness of its structure directly has influence on the performance of battery-driven car, the wheel hub of existing rear wheels of electric vehicle and motor are integral type, its bearing capacity acts on electric machine casing, electric machine casing is easily deformed and damage under the effect of long-term bearing capacity; And wheel hub and motor are the integral type structure, the motor that causes its use can only be slowspeed machine (400R/min left and right), can't use high-speed electric expreess locomotive (more than 3500R/min), cause its hill climbing ability low, during climbing, discharge rate is higher, has affected the flying power of battery-driven car and the life-span of battery.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of long service life, rear wheels of electric vehicle mechanism that hill climbing ability is strong.
In order to solve the problems of the technologies described above, the utility model provides a kind of rear wheels of electric vehicle mechanism, comprise: motor, the change speed gear box that is in transmission connection with the output shaft of motor, the free-wheel clutch that is in transmission connection with transmission gear in this change speed gear box, with the coaxial wheel hub terminal pad that is fixedly connected with in outer end of the output sleeve of this free-wheel clutch; This wheel hub terminal pad bearing is connected on the main shaft of rear wheels of electric vehicle and with a side of the wheel hub of this rear wheels of electric vehicle, is fixedly connected with; Hub bearing is connected on main shaft.
The another side of described wheel hub is provided with brake gear.
Brake gear is disc brake device.
Described motor is the high-speed electric expreess locomotive of rotating speed greater than 3.5kr/min.
Motor is fixed on change speed gear box, and free-wheel clutch is located in change speed gear box.
Technique effect of the present utility model:: the change speed gear box in rear wheel mechanism of the present utility model, wheel hub are the axis structure, and each parts demolition, installation are convenient; Simultaneously because the space, installation site of motor is larger, so can adopt the high-speed electric expreess locomotive of 3.5kr/min and above rotating speed, with respect to the existing battery-driven car that can only adopt the slowspeed machine of 0.4kr/min revolution, have that starting is fast, hill climbing ability strong and (can climb angle and be the slope of 20 °, prior art only can 9 ° of slopes), the climbing discharge is little, cruising radius is long advantage, be suitable for intermountain and drive; Simultaneously, owing to having applied high-speed electric expreess locomotive, the precious materials consumption reduces, and cost can significantly reduce, and has saved simultaneously the precious materials such as rare earth.
