Abstract
The utility model discloses an electric-tricycle rear-wheel shock absorbing structure, and belongs to the field of electric tricycles. The electric-tricycle rear-wheel shock absorbing structure comprises a tricycle frame, shock absorbing springs and a brake axle tube, wherein the brake axle tube is connected with rear wheels. The electric-tricycle rear-wheel shock absorbing structure further comprises upper support arms and lower support arms, the cross section of the tricycle frame is in a T shape, one end of each of the upper support arms is movably connected with the middle of the upper end of the tricycle frame, the other end of each of the upper support arms is movably connected with the upper portion of the brake axle tube, one end of each of the lower support arms is movably connected with the lower portion of the tricycle frame, and the other end of each of the lower support arms is movably connected with the lower portion of the brake axle tube. One end of each of the shock absorbing springs is connected with the middle portion of each lower support arm, and the other end of each of the shock absorbing springs is connected with the tricycle frame. One upper support arm is arranged at left, the other upper support arm is arranged at right, and the two upper support arms are in left-right symmetrical relationship when the central axis of the tricycle frame serves as an axis. One lower support arm is arranged at left, the other lower support arm is arranged at right, and the two lower support arms are in left-right symmetrical relationship when the central axis of the tricycle frame serves as an axis. One shock absorbing spring is arranged at left, the other shock absorbing spring is arranged at right, and the two shock absorbing springs are in left-right symmetrical relationship when the central axis of the tricycle frame serves as an axis. The electric-tricycle rear-wheel shock absorbing structure has the advantages that the structure is simple, a left wheel and a right wheel are suspended independently, the weight of the electric-tricycle rear-wheel shock absorbing structure is light, and shock absorbing activity scope is large.
Description
Technical field
The present invention relates to a kind of electro-tricycle product, relate in particular to a kind of electro-tricycle rear wheel shock-absorbing structure, belong to the electro-tricycle field.
Background technology
Electro-tricycle is to be power in order to storage battery, and motor is hauling goods of driving or three-wheel transportation means that holding is used.At present, the damping modes of electro-tricycle is a lot of on the market, trends towards the integral type damping mostly, and weight is big; Manufacturing cost is high, and part, parts are many, and manufacturing technology complicacy and volume are big, heavy; Damping effect is not good, and waste of power is serious, is inappropriate for light, a three-wheeled electric vehicle use.
Summary of the invention
To the problem that above-mentioned prior art exists, the present invention provides a kind of electro-tricycle rear wheel shock-absorbing structure, have simple in structure, independent suspension, in light weight, the effect that the damping action radius is big.
To achieve these goals; The technical scheme that the present invention adopts is: a kind of electro-tricycle rear wheel shock-absorbing structure, comprise vehicle frame, damping spring, braking bridge tube, and the braking bridge tube connects trailing wheel; Also comprise upper branch arm and lower branch arm; Said vehicle frame is T type cross section, and the middle part of an end of upper branch arm and vehicle frame upper end flexibly connects, and the other end of upper branch arm is connected with the top movable of braking bridge tube; One end of lower branch arm and vehicle frame bottom flexibly connect, and the other end of lower branch arm flexibly connects with the bottom of braking bridge tube; Damping spring one end is connected with the lower branch arm middle part, and the damping spring other end connects to ground; Said upper branch arm, lower branch arm, damping spring be about each one and be a left-right symmetric with the vehicle frame axis.
Said upper branch arm and lower branch arm be built-in damping gum cover in connection procedure.
Each fixing hanger of described vehicle frame right ends, hanger is connected with damping spring through bolt.
Said upper branch arm is connected with the braking bridge tube through bearing pin respectively with lower branch arm.
The invention has the beneficial effects as follows: simple in structure, the left and right wheels independent suspension, in light weight, the damping action radius is big.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a birds-eye view of the present invention;
Among the figure: 1, trailing wheel, 2, the braking bridge tube, 3, upper branch arm, 4, lower branch arm, 5, damping spring, 6, hanger, 7, vehicle frame.
The specific embodiment
To combine accompanying drawing that the present invention is described further below.
As depicted in figs. 1 and 2; The present invention includes vehicle frame 7, damping spring 5, braking bridge tube 2; Braking bridge tube 2 connects trailing wheel 1, also comprises upper branch arm 3 and lower branch arm 4, and said vehicle frame 7 is T type cross section; The middle part of one end of upper branch arm 3 and vehicle frame 7 upper ends flexibly connects, and the other end of upper branch arm 3 is connected with the top movable of braking bridge tube 2; One end of lower branch arm 4 and vehicle frame 7 bottoms flexibly connect, and the other end of lower branch arm 4 flexibly connects with the bottom of braking bridge tube 2; Damping spring 5 one ends are connected with lower branch arm 4 middle parts, and damping spring 5 other ends connect to ground; Said upper branch arm 3, lower branch arm 4, damping spring 5 be about each one and be a left-right symmetric with vehicle frame 7 axis; Said upper branch arm 3 and lower branch arm 4 built-in damping gum cover in connection procedure; Each fixing hanger 6 of described vehicle frame 7 right ends, hanger 6 is connected with damping spring 5 through bolt; Said upper branch arm 3 is connected with braking bridge tube 2 through bearing pin respectively with lower branch arm 4.
The present invention can be given a shock when jolting by side wheel, damping spring 5 vibrations of this side, and the last lower branch arm of this side rotates around bearing pin; Very little to the influence of other wheels simultaneously; Thereby three wheels have been formed separately independently shock mitigation system, have simple in structurely, and two rear wheel shock-absorbings are separate; Good damping effect, the effect of minimizing waste of power.
