Abstract
The utility model relates to a rear wheel hub of an electric vehicle, which comprises a wheel rim, a connecting flange arranged at the center of the wheel rim, and multiple groups of spokes centrosymmetrically distributed on the connecting flange, wherein the outer ends of each group of spokes are connected with the inner wall of the wheel rim; the connecting flange, the spokes and the wheel rim are formed integrally. The rear wheel hub has a simple structure, and the connecting flange, the spokes, and the wheel rim are formed integrally, so that the structure is firm and the service life is long; a gear box and the hub in a rear wheel mechanism adopt a through shaft structure, so that each part can be demounted and mounted conveniently; meanwhile, as the mounting position space of a motor is larger, a high speed motor with the rotating speed of 3.5 kr/min or greater than that can be adopted; compared with a conventional electric vehicle which can only adopt a low speed motor with the rotating speed of 0.4 kr/min, the electric vehicle adopting the high speed motor has the advantages of fast starting, strong climbing ability, low climbing electrical discharging, and long cruising distance, and is suitable for intermountain driving.
Description
Technical field
The utility model relates to a kind of rear wheels of electric vehicle wheel hub.
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 under the effect of long-term bearing capacity and damage; 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 rear wheels of electric vehicle wheel hub of simple in structure, long service life.
In order to solve the problems of the technologies described above, the utility model provides a kind of rear wheels of electric vehicle wheel hub, comprising: wheel rim, be located at the butt flange of wheel rim one side central authorities, and Central Symmetry is distributed in the many groups spoke on this butt flange; Each outer end of organizing spoke is connected with the inwall of wheel rim; Described butt flange, spoke and wheel rim are one-body molded.
Described butt flange is connected with a main shaft bearing, butt flange one side coaxially is provided with the wheel hub terminal pad and is connected, described main shaft head bearing is connected with free-wheel clutch, and this free-wheel clutch is in transmission connection by a transmission gear and change speed gear box, and the output shaft of change speed gear box and a motor is in transmission connection.
The described spoke of respectively organizing is Y-shaped.
The opposite side of described wheel hub is provided with brake gear; One side of described butt flange is provided with one for placing the brake chamber of brake gear.
Described brake gear is disc brake device.
The utility model has positive effect with respect to prior art: rear wheels of electric vehicle wheel hub structure of the present utility model is simple, and butt flange, spoke and wheel rim are one-body molded, therefore structure is firm, and long service life; Change speed gear box in rear wheel mechanism, 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 (can be climbed the slope that angle is 20 ° by force, prior art only can 9 ° of slopes), the climbing electric discharge is little, cruising radius is long advantage, be suitable for intermountain and drive; Owing to having applied high-speed electric expreess locomotive, the precious materials consumption reduces, and cost can significantly reduce, and has saved the precious materials such as rare earth simultaneously.
