Abstract
The utility model provides a rear shock absorbing mechanism for an electric vehicle. The rear shock absorbing mechanism comprises a rear shock absorbing supporting base, a rear swing arm and a rear shock absorber, wherein a body of the rear shock absorbing supporting base is composed of a square plate, the center of the lower portion of the body is provided with a wheel shaft hole position, a rear wheel shaft is arranged in the wheel shaft hole position in a sleeved mode, and the lower side of the outer wall of the wheel shaft hole position is concave and is located in a swing arm shaft at the bottom of the body; two supporting points of the rear swing arm are movably hinged to the two ends of the swing arm shaft respectively through ball ends to form an independent suspension; one corner portion of the upper end of the body is provided with a rear braking fixing position, and a rear brake is arranged on the rear braking fixing position; the other corner portion of the upper end of the body extends upward to form a rear shock absorbing fixing position, and the rear shock absorber is arranged on the rear shock absorbing fixing position. The rear shock absorbing mechanism has the advantages of being simple in structure and reasonable in layout, can guarantee comfort and smoothness of a vehicle in any load state, and is remarkably improved in cost, comprehensive performance and other aspects.
Description
Technical field
The utility model should relate to automobile manufacturing field, refers in particular to a kind of rear damping for electronlmobil.
Background technology
The raising to environmental protection consciousness along with social development and people; the electronlmobil that the clean energy resource of take is master is able to fast development; electronlmobil refers to take vehicle power as power, with power wheel, travels, and meets the vehicle of arteries of communication, legislative control on safety requirements.Due to less to the relative orthodox car of environmental concerns, its prospect is extensively had an optimistic view of, and its principle of work is: storage battery, and---------electrical motor---power drive system---drives running car to electric governor to electric current; But also there are some technical shortcomings in existing electronlmobil: as adopted nonstandard two-thread screw to be connected because screw rod centre portion is equivalent to a kinematic axis between the rear-swing arm of rear damping and fixed block, requirement of strength that will be very high, long-term use caused screw rod wearing and tearing, the bending resistance torsional property of screw rod reduces, and very easily bends or ruptures and vehicle trouble occurs.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of for simple in structure, the connection and reasonable arrangement of electronlmobil, the rear damping that stability is high, traveling comfort is good.
For achieving the above object, technical scheme provided by the utility model is: a kind of rear damping for electronlmobil, it includes rear shock mount, rear-swing arm, rear shock absorber, rear shock mount main body consists of a square plate body, lower body part central authorities are provided with axle hole position, hind axle is sleeved in axle hole position, the recessed arm shaft that is positioned at bottom part body of axle hole position outer wall downside; Two fulcrums of rear-swing arm are movably articulated in arm shaft two ends by a bulb respectively and form independent suspension; One of them rotation angle position of main body upper end is provided with rear braking fixed bit, and rear brake is arranged on rear braking fixed bit; Damping fixed bit after another rotation angle position of main body upper end extends upward and forms, rear shock absorber is arranged on rear damping fixed bit.
Described hind axle one end is assemblied in wheel hub motor, and the other end is sleeved in axle hole position through after rear brake disc.
Described rear brake is arranged on rear braking fixed bit, and be arranged on rear brake disc on hind axle and match wheel is braked.
Described rear shock absorber bottom is connected with rear damping fixed bit, and rear shock absorber top is connected with vehicle frame.
This programme is simplified whole rear shock mitigation system, two fulcrums of rear-swing arm are movably articulated in arm shaft two ends by a bulb respectively and form independent suspension, end is urgent by bolt again, make rear damping can not cause wearing and tearing when motion, simple in structure, favorably situated advantage that this programme has, and under various load conditions, can go up vehicle and guarantee comfortable ride comfort, and at aspects such as cost, Combination properties, have raising significantly.
Accompanying drawing explanation
Fig. 1 is integral structure schematic diagram of the present utility model.
Fig. 2 is the fractionation schematic diagram of Fig. 1.
Fig. 3 is rear shock mount front schematic view of the present utility model.
Fig. 4 is rear shock mount side schematic view of the present utility model.
The specific embodiment
Below in conjunction with institute's drawings attached, the utility model is described in further detail, and preferred embodiment of the present utility model is; Referring to accompanying drawing 1 to accompanying drawing 4, rear damping for electronlmobil described in the present embodiment includes rear shock mount 1, rear-swing arm 2, rear shock absorber 6, rear shock mount 1 main body consists of a square plate body, lower body part central authorities are provided with axle hole position 105, hind axle 7 one end are assemblied in wheel hub motor 4, and the other end is sleeved in axle hole position 105 through after rear brake disc 3.The wheel hub motor 4 of the present embodiment adopts the pm brushless in-wheel motor driver train of development voluntarily, to reach, alleviates vehicle weight, reduces noise, makes the longer object of running time.The recessed arm shaft 106 that is positioned at bottom part body of axle hole position 105 outer wall downsides; Two fulcrums of rear-swing arm 2 are movably articulated in arm shaft 106 two ends by a bulb respectively and form independent suspension; Tradition rear-swing arm adopts nonstandard two-thread screw to connect because screw rod centre portion is equivalent to a kinematic axis, requirement of strength that will be very high, long-term use caused screw rod wearing and tearing, and the bending resistance torsional property of screw rod reduces, and very easily bends or ruptures and vehicle trouble occurs.Two fulcrums of rear-swing arm are movably articulated in arm shaft two ends by a bulb respectively and form independent suspension, and end is urgent by bolt again, make rear damping can not cause wearing and tearing when motion.One of them rotation angle position of main body upper end is provided with rear braking fixed bit 102, and rear brake 5 is arranged on rear braking fixed bit 102, and be arranged on rear brake disc 3 on hind axle 7 and match wheel is braked.Damping fixed bit 101 after another rotation angle position of main body upper end extends upward and forms, rear shock absorber 6 bottoms are connected with rear damping fixed bit 101, and rear shock absorber 6 tops are connected with vehicle frame, make vehicle effectively increase under steam buffering effect.Simple in structure, favorably situated advantage that this programme has, and can go up vehicle guarantee comfortable ride comfort under various load conditions, and at aspects such as cost, Combination properties, have significantly and improve.
The embodiment of the above is only the preferred embodiment of the utility model, not with this, limits practical range of the present utility model, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection domain of the present utility model.
