The damping device for the electric tricycle is obvious in shock absorbing function and can greatly improve riding comfortableness of the electric tricycle.
Description
Technical field
The utility model relates to damper of vehicle, specifically, relates to a kind of damping device for electric tricycles.
Background technology
In prior art, the shock absorption device that electro-tricycle adopts is the leaf spring damping, because the leaf spring shock-stiffness is larger, when running into the road surface of jolting, almost there is no shock-absorbing functions, thereby has greatly affected the traveling comfort of taking.
The utility model content
The purpose of this utility model is, a kind of damping device for electric tricycles is provided, to solve above-mentioned technical matters.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of damping device for electric tricycles is characterized in that: comprise two belows that are symmetricly set on vehicle rear axle and with perpendicular lower limb arm, two non-linear shock-damping springs that are positioned at the vehicle rear axle front side and two hydraulic dampers that are positioned at the vehicle rear axle rear side of vehicle rear axle; The front end of described lower limb arm is fixedly connected with the hanger of bottom of frame, and the rear portion of lower limb arm is fixedly connected with vehicle rear axle; Described non-linear shock-damping spring vertically arranges, and its top is arranged on the bottom of vehicle frame by the spring perch correspondence, and its bottom is arranged on the lower limb arm by the spring perch correspondence; Described hydraulic damper vertically arranges, and its top is connected with the bottom of vehicle frame tail end, and its bottom is connected with the tail end of lower limb arm.
Say further, described shock absorption device also comprises trammel beam, and described trammel beam comprises a horizon bar and a longitudinal rod; The bottom of described longitudinal rod is connected with vehicle rear axle; One end of described horizon bar and the top of longitudinal rod are hinged, and its other end is hinged on vehicle frame.
Beneficial effect: compared with prior art, the utility model shock-absorbing functions is obvious, can greatly improve the travelling comfort of vehicle.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is birds-eye view of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, damping device for electric tricycles described in the utility model, comprise two belows that are symmetricly set on vehicle rear axle 4 and with the perpendicular lower limb arm of vehicle rear axle 47, two non-linear shock-damping spring 2 and two hydraulic dampers 5 that are positioned at vehicle rear axle 4 rear sides that are positioned at vehicle rear axle 4 front sides.The front end of described lower limb arm 7 is fixedly connected with the hanger 8 of vehicle frame 1 bottom by bolt 9, and the rear portion of lower limb arm 7 is fixedly connected with vehicle rear axle 4 by clevis bolt 6.
Described non-linear shock-damping spring 2 vertically arranges, and its top is arranged on the bottom of vehicle frame 1 by the spring perch correspondence, and its bottom is arranged on lower limb arm 7 by the spring perch correspondence.Non-linear shock-damping spring 2 has the composite elastic coefficient, general said gradual spring namely, and its effect is: 1,, as the buffering on suspension or chassis and ground, namely maintain traveling comfort; 2, make vehicle keep the subsides ground property of tire when passing through uneven road surface.Running into the softer spring of our needs of road surface more jolted.
Described hydraulic damper 5 vertically arranges, and its top is connected with the bottom of vehicle frame 1 tail end, and its bottom is connected with the tail end of lower limb arm 7.Concussion when hydraulic damper 5 is mainly used to suppress bounce-back after 2 shock-absorbings of non-linear shock-damping spring and from the impact on road surface.Through uneven road surface the time, although non-linear shock-damping spring 2 can filter the vibrations on road surface, himself also has crank motion, and hydraulic damper is exactly for suppressing this jump of non-linear shock-damping spring 2.It is very important that hydraulic damper 5 will be arranged in pairs or groups mutually with non-linear shock-damping spring 2.Hydraulic damper 5 can reach lower natural frequency (general 5HZ is following), can obtain larger quiet too amount of compression (usually 30MM amount of compression), and can bear larger load.
Due to the poor shortcoming of non-linear shock-damping spring 2 existence and stabilities, in order to make up this shortcoming, prevent that vehicle body from rocking, added again trammel beam.Described trammel beam comprises a horizon bar 31 and a longitudinal rod 32; The bottom of described longitudinal rod 32 is connected with vehicle rear axle 4; One end of described horizon bar 31 and the top of longitudinal rod 32 are hinged, and its other end is hinged on vehicle frame 1.So, the stability of car load can be guaranteed, its travelling comfort can be kept again.
The utility model goes for other motor tricycles vehicles equally.
