Description
Technical field
The utility model relates to automotive field, the automobile running system that is specifically related to the connection structure between automobile axle and the vehicle frame and has this structure.
Background technology
Usually be connected by automotive suspension (for example steel spring) between automobile axle and the vehicle frame, steel spring plays car load travelled carries out damping, transmits effects such as driving, braking and carrying.As shown in Figure 1, traditional automobile axle and the connection structure between the vehicle frame generally include vehicle frame 1, back axle 2 and rear leaf spring 3, described rear leaf spring 3 is arranged on the top of described back axle 2, and the middle part of described rear leaf spring 3 is connected with described back axle 2 by clevis bolt 4, and the two ends of described rear leaf spring 3 are connected with described vehicle frame 1 by spring carrier 5.Because rear leaf spring 3 is arranged on the top of back axle 2, so the car load center of gravity is higher, anti-roll capability is lower, thereby the driving safety of automobile is impacted.Pursuing high-mechanic, high-speed today, lowering the center of gravity is even more important for running safety.
In addition, some goods carrying vehicles are because of after the container barycenter leans on, and the cargo capacity requirement is very high, so require the rear axle bearing load much larger than the front axle bearing load, thereby the non-deformability that requires rear leaf spring 3 far is better than the non-deformability of front spring spring 6, therefore cause rear leaf spring 3 thick more a lot, and in design, also might design trailing wheel bigger than front-wheel than front spring spring 6.Above-mentioned reason causes car load low early and high after very serious, and attitude is very poor.Even some vehicle can only be made low early and high after variable shaped beam with vehicle frame 1, thereby has increased the difficulty of vehicle frame 1 forming process, has improved manufacturing cost.
The utility model content
The automobile running system that the purpose of this utility model is to provide a kind of automobile axle that can reduce the car load center of gravity and the connection structure between the vehicle frame and has this structure.
The utility model provides the connection structure between a kind of automobile axle and the vehicle frame, this connection structure comprises vehicle frame, back axle and rear leaf spring, the middle part of described rear leaf spring is connected with described back axle, the two ends of described rear leaf spring are connected with described vehicle frame, wherein, described rear leaf spring is arranged on the below of described back axle.
The utility model also provides a kind of automobile running system, this automobile running system comprises vehicle frame, propons, back axle, front spring spring and rear leaf spring, the middle part of described front spring spring is connected with described propons, the two ends of described front spring spring are connected with described vehicle frame, the middle part of described rear leaf spring is connected with described back axle, and the two ends of described rear leaf spring are connected with described vehicle frame, wherein, described rear leaf spring is arranged on the below of described back axle, and described vehicle frame is a straight beam.
Because rear leaf spring moves on to the below of back axle from the top of back axle, thus can correspondingly the two ends bonded assembly vehicle frame with rear leaf spring be moved down, thus reduced the center of gravity of car load, improve anti-roll capability, thereby improved the driving safety of automobile.In addition, owing to move down with the rear portion of the two ends bonded assembly vehicle frame of rear leaf spring, so even rear leaf spring is thicker than front spring spring, the backgear ratio front-wheel is big, also can relax low early and high after too class-one defect in the prior art, thereby can improve the aesthetics of car load attitude.And, need not vehicle frame is made low early and high after variable shaped beam, thereby reduced the difficulty of vehicle frame forming process, reduced manufacturing cost.
