Abstract
The utility model discloses an integrated single-oblique-arm deceleration type rear-wheel hub electric-driving automobile power system which comprises front wheels, a frame, an elastic rubber hinge, a single-oblique-arm suspension swing arm, a speed reducer, a rear wheel motor, rear wheels and a semi-shaft sleeve, wherein the elastic rubber hinge, the single-oblique-arm suspension swing arm, the speed reducer, the rear wheel motor and the semi-shaft sleeve are fixed into a whole; the elastic rubber hinge supports the frame; the speed reducer is provided with a power input end and a power output end; the rear-wheel motor is a high-speed motor; power is inputted to the speed reducer through the power input end of the speed reducer and is decelerated by gears in the speed reducer; and power is outputted to the rear wheels through the power output end of the speed reducer through the semi-shaft sleeve by a semi-shaft. The integrated single-oblique-arm deceleration type rear-wheel hub electric-driving automobile power system has the advantages of high motor specific power, small size and light weight; and after deceleration and torque increasing, the output torque is large, and the climbing acceleration performance is better, so that the equivalent unsprung weight is effectively reduced.
Description
Technical field
The utility model relates to a kind of electronlmobil field, particularly a kind of integrated monocline arm slowdown type rear wheel rotation limit electric drive automobile power system.
Background technology
Electronlmobil can be divided into single motor centralized driving type and distributed driving according to the type motor-driven difference.Both are main difference: the former generally passes through retarder, diff and transmission shaft drive wheels by a motor; The latter then is installed in a plurality of motors respectively in the drive wheel, forms wheel hub motor direct drive wheel, or drive motor is arranged near on the vehicle frame of drive wheel, and again via each retarder and transmission shaft drive wheels, promptly slowdown type wheel limit electricity drives pattern.The distributed driving mechanical differential gear box that omits has simple for structure, transmission characteristics of high efficiency, and each driving wheel torque is independent controlled, at car load road-holding property controlling party mask very big development potentiality is arranged.
The electrically operated advantage in described slowdown type wheel limit is its motor specific power height, little, the light weight of volume, and increases by deceleration and to turn round that its output torque of back is big, the climbing acceleration capability is better; And can guarantee that automobile obtains bigger steady torque when low speed.Its deficiency shows has increased speed reduction gearing, thereby has increased nonspring carried mass, also need solve simultaneously retarder noise problem that the high speed transmission brings etc.
Described wheel hub motor direct drive pattern for guaranteeing starting smoothly, requires motor that big torque is provided when low speed, and for making automobile possess certain dynamic property, motor needs the speed adjustable range of broad simultaneously.The advantage of direct drive is not have speed reduction gearing, makes whole drive wheel structure simpler, compact, and axial dimension also reduces, and efficient further improves, and speed of response also accelerates.Shortcoming needs big electric current, fragile permanent magnet when being starting, the big torque of climbing equivalent-load; The efficient district of motor is narrower, low speed high torque operating mode inefficiency; In addition, it is bigger than normal that the wheel hub motor direct drive also easily causes unsprung weight.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of maintenance slowdown type wheel limit electrically operated advantage, simultaneously also reduce nonspring carried mass, improved the ground connection property of vehicle, the integrated monocline arm slowdown type rear wheel rotation limit electric drive automobile power system of ride comfort.
In order to solve above technical matters, the utility model provides a kind of integrated monocline arm slowdown type rear wheel rotation limit electric drive automobile power system, this system comprises front-wheel, vehicle frame, the elastic caoutchouc hinge, the swing arm of monocline arm sling frame, retarder, back turbin generator, trailing wheel, axle tube, wherein, the elastic caoutchouc hinge, the swing arm of monocline arm sling frame, retarder, back turbin generator, axle tube is fixedly installed in together, the elastic caoutchouc hinged bearing is in vehicle frame, retarder is provided with power intake and clutch end, back turbin generator is a high-speed electric expreess locomotive, by the retarder power intake power is imported retarder, gear reduction in retarder passes through axle tube by semiaxis and exports power to trailing wheel from the clutch end of retarder.
Two front-wheels are for turning to flower wheel, and two trailing wheels are slowdown type wheel limit electricity type of drive pattern.
The barycenter of described back turbin generator and retarder is arranged and is close to monocline arm sling frame axis of oscillation place.
Superior effect of the present utility model is: trailing wheel adopts integrated monocline arm slowdown type wheel limit power drive system, have motor specific power height, little, the light weight of volume, and increase by deceleration turn round that its output torque of back is big, climbing acceleration capability characteristics preferably, can effectively reduce its equivalent nonspring carried mass by the position of reasonable Arrangement wheel limit parts simultaneously.
