Description
Technical field:
The invention belongs to the electric vehicle engineering field, be specifically related to torsion beam independent suspension system behind a kind of electronlmobil.
Background technology:
Automobile chassis frame or vehicle body are if direct mount on vehicle bridge or wheel, because road is uneven, can feel very uncomfortable owing to ground shock makes goods and people, and this is because there is not the reason of draft hitch.Automotive suspension is the general designation of the elastic coupling device between vehicle frame or vehicle body and axletree or the wheel.Its effect is flexibly to connect vehicle bridge and vehicle frame or vehicle body, relaxes the impulsive force that vehicle receives in going.Guarantee that goods is intact comfortable with personnel; Decay improves road-holding property because the vibration that elastic system is introduced makes the stable posture of maintenance in the running car; Simultaneously suspension system is being born the transmission vertical reaction, vertically counter-force (tractive force and braking force) and lateral reaction and moment loading that these power caused on vehicle frame or vehicle body, smooth-going with the assurance running car; And when the relative vehicle frame of wheel was beated, when turning to, wheel trace will meet certain requirement especially, so suspension also works the directional tagging that wheel is beated by the relative vehicle body of certain track.Rationally whether the selection of suspension frame structure form and performance perameter directly has very big influence to vehicle running smoothness, road-holding property and traveling comfort.This shows that suspension system is one of important assembly on the automobile in modern times.
Environmental pollution, lack of energy, people explore, develop, utilize regenerative resource to drive automobile.Have now found that and develop like new-energy automobiles such as wind power automobile, magnetic motive force automobile, solar cars; But these new-energy automobile complex structures; Build is clumsy, inefficiency, and be not suitable for long-distance operation; Therefore these new-energy automobile practical uses are little, therefore fail to access large-area applying.
For solving existing environmental problem and energy problem, electronlmobil has also been promoted in people's research and development, and electronlmobil is with its zero-emission being accepted by people gradually, and; Along with the development of electric vehicle engineering, it is original can not long-distancely to use and the charging problem is resolved gradually, therefore; The user of electronlmobil is more and more, still, and electronlmobil in the market; The automotive suspension that it adopted especially rear overhang mounts to put and still adopts traditional suspension, i.e. many connecting rods Mai Fuxun rear linkage, traditional many connecting rods rear linkage complex structure; Weight is heavier, and to making whole tare heavy, its energy that can carry of electronlmobil is originally just limited; Therefore, should reduce the vehicle body deadweight as much as possible, reduce the energy dissipation of unnecessary ability; Make the limited energy be used in steam supply garage as much as possible and reach, therefore, traditional many connecting rods rear linkage can not satisfy the needs of electronlmobil development.
Summary of the invention:
In sum, in order to overcome the deficiency of prior art problem, the invention provides torsion beam independent suspension system behind a kind of electronlmobil; It is that the back torsion beam is set between the hind axle of the electronlmobil back rest and automobile, through the back torsion beam automobile back rest is connected with hind axle, replaces original many connecting rods Mai Fuxun rear linkage; Simple in structure, safe and reliable, installation and maintenance are convenient; In light weight, can effectively reduce electronlmobil deadweight, self resistance when reducing electric automobile during traveling; Improve the travelled distance of electronlmobil effectively, energy savings.
For solving the problems of the technologies described above, technical scheme of the present invention is achieved in that
Torsion beam independent suspension system behind a kind of electronlmobil comprises the automobile back rest, and wherein: the described automobile back rest is fixed with an end of back torsion beam; The other end of back torsion beam is connected with the automobile back wheel axle, and back torsion beam is " H " type, and the automobile back wheel outer shaft sleeve has axle sleeve; Be fixed with electric machine support on the axle sleeve; Motor is arranged on the electric machine support, and the output shaft of motor is connected with the input shaft of reductor, and the output shaft of reductor is connected with the automobile back wheel axle; Motor via reducer drives the automobile back wheel axle and rotates, and the two ends of automobile back wheel axle are provided with automobile back wheel.
Technical scheme of the present invention can also be achieved in that the described automobile back rest is provided with channel-section steel, and channel-section steel tips upside down on the automobile back rest, and the front end of back torsion beam inserts in the groove of channel-section steel and the formation of the automobile back rest, and passes through bolt.
Technical scheme of the present invention can also be achieved in that described back torsion beam and automobile back wheel axle bonded assembly one end are provided with clamping plate, " n " type that is shaped as of clamping plate, and clamping plate are clamped the automobile back wheel axle, and fix through bolt and automobile back wheel axle.
Technical scheme of the present invention can also be achieved in that the described automobile back rest through U-bolt with the back torsion beam fix.
Beneficial effect of the present invention is:
1, the present invention adopt be between the electronlmobil back rest and automobile back wheel axle, be provided with the back torsion beam, through the back torsion beam automobile back rest is connected with hind axle, replace original many connecting rods Mai Fuxun rear linkage; Simple in structure, safe and reliable, installation and maintenance are convenient; In light weight, can effectively reduce electronlmobil deadweight, self resistance when reducing electric automobile during traveling; Improve the travelled distance of electronlmobil effectively, energy savings.
2, of the present invention simple in structure firm, easy to maintenance, reduced fault rate, reduced manufacturing cost and use cost; More alleviated car body weight; The not only energy-conservation mileages of continuation that has also prolonged electronlmobil to a great extent; The limited energy that electronlmobil is carried, being used on the running car as much as possible reduces unnecessary energy loss.
