Embodiment
Below by embodiment, and with reference to accompanying drawing, technical scheme is described in further detail.
Embodiment:All-terrain vehicle rear suspension system of the present invention, as shown in Figure 1, it includes:It is in substantially parallel relationship to longitudinal direction of car
The damper 4 of plane, the two secondary rear trailing arms 5 for being placed in the engine back lower place, and torque arm 11.
As shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, rear trailing arm 5 is pipe frame structure, including the trailing arm sleeve pipe being connected with vehicle frame 21
13, the both ends of trailing arm sleeve pipe 13 set the first bend pipe 14 and the second bend pipe 15, the end of the first bend pipe 14 and the phase of the second bend pipe 15 respectively
Connect, reinforcing plate, reinforcing plate side wall and institute are set in the space that the bend pipe 14 of trailing arm sleeve pipe 13 first and the pipe of the second bend pipe 15 3 wrap
Body in side connects;Support tube 19 is set on the body of second bend pipe 15, support tube 19 connects the lower end of damper 4, supported
The end of the bend pipe 15 of pipe 19 and second sets axle support 20.This pipe frame structure of rear trailing arm 5, and this pipe support and reinforcing plate
Integral solder(Reinforcing plate side wall connects with the body of place side, and bonding strength is high)Integrative-structure, greatly improved overall strong
Degree, is unlikely to deform, is not easy to break, rear trailing arm 5 is had higher bulk strength, large carrying capacity, improve impact resistance;
Based on this post-suspension structure, when all-terrain vehicle travels on complicated landform, the anti-ability of jolting is strengthened.
Torque arm 11 is horizontal below rear trailing arm 5, end set torque arm connecting rod 12, and torque arm connecting rod 12, which is upward through, to be added
Strong plate is simultaneously connected to the body of rear trailing arm 5, is preferably fixed on the body of the second bend pipe 15.Torque arm 11 improves all-terrain vehicle
Stationarity, using the technical program, reduce the position of the main body of torque arm 11, it is lower slightly compared to torque arm in conventional art 11
Or the organization plan higher than rear trailing arm, the technical program fully release suspension upper space, make suspension movement travel big.
The connection end that axle support is connected to for the intensity of further raising rear trailing arm 5, especially raising rear trailing arm 5 is strong
Degree, is that the endpiece of the first bend pipe 14 is the first branch pipe 141 and the end phase of the second branch pipe 142 as a preferable technical scheme
The bifurcation structure for connecing and forming, i.e. the first bend pipe 14, the first branch pipe 141 and the three of the second branch pipe 142 are connected with one end;Second
The endpiece bending of bend pipe 15 is in horizontal, horizontal section 151 of tail end connection axle support 20, head end the first branch pipe 141 of connection;Second
Branch pipe 142 is fixedly connected on support tube 19.Support member 191, support member are set in the side wall of support tube 19 away from the side of the second branch pipe 142
Axle support 20 is fixed in 191 ends;The branch pipe 141 of support member 191 and first is split in the both sides of support tube 19, can improve support tube 19
Support strength.In the technical program, have the following advantages that:First, the endpiece bending of the second bend pipe 15 is in horizontal, horizontal section
151 connection axle supports 20, bigger space is provided for attended operation, is easy to attended operation, particularly horizontal structure conduct
Connecting portion, compared to incline structure, deformation is not easy, and stress equalization is more preferably, makes the stability of connecting portion higher;Second, the
One branch pipe 141 is connected to horizontal section 151 of tail end, and support is provided for horizontal section 151;Third, the second branch pipe 142 is fixedly connected
In support tube 19, the both ends of support tube 19 are made to have supporting construction(I.e.:Both ends are carried by the second branch pipe 142 and the second bend pipe 15 respectively
For support), intensity is higher;Fourth, the endpiece bifurcated of the first bend pipe 14 is the first branch pipe 141 and the second branch pipe 142, improving
While bulk strength, also with space hold it is small the advantages of.
For the structure of the endpiece bifurcated of above-mentioned first bend pipe 14, the first branch pipe 141 and the second branch pipe 142 can be single
Individual, then end connect;It is that in the first branch pipe 141 and the second branch pipe 142, one is first as a preferable scheme
Bend pipe 14 extends the body formed, and another is the body for being fixed on the sidepiece of the first bend pipe 14, and this mode, structural strength is more
It is high;Further preferred mode is that the first branch pipe 141 is formed by the bending of the body of the first bend pipe 14, welding is in the first bend pipe 14
Outside, it is easy to operation.
Support tube 19 is erected at the top of the first branch pipe 141, and the connecting portion of support tube 19 and the second bend pipe 15 is in and closed on
On the body of horizontal section 151 of the second bend pipe 15.Under vertical view, the second bend pipe 15, the first branch pipe 141, the three of support tube 19 are in
The framework of triangle intersection, further increases bulk strength.
