Under power, it can only transmit the load of vertical direction.And pendulum spring structure of the present utility model is when changing length, it is optional with
Vertical direction has certain angle, i.e. the direction of inclined upward to the left in fig. 11.Using the pendulum spring structure of this kind of structure,
More preferable suspension behavior can be obtained, when adjusting bodywork height, can not only carry the vertical load of vertical direction, can also
The horizontal load in load level direction, power and moment of torsion are preferably transmitted between wheel and vehicle body, ensure suspension regulation process
It is steady to carry out.

And the first position of suspension holdfast 22 is kept to press close to wheel 41, i.e. the connection first position 221 of suspension holdfast 22 and the 3rd
Put 223 support arm and the angle β of vertical direction further increases.So, the combining structure of suspension device for vehicle and wheel 41
Whole height is smaller, but the length of the combining structure horizontal direction can increase in fig. 11, goes for whole to wheel case
Body requirement for height is smaller, and the situation that the pitch requirements of adjacent wheels are larger.When the pitch requirements of adjacent wheels are smaller, then need
The installation site of pendulum spring structure 1 is moved to the opposite direction in S directions, reduces the length of combining structure in the horizontal direction,
And add the whole height of combining structure.
