Abstract
The utility model belongs to the field of electric vehicles, and particularly relates to a front axle damper for a four-wheel electric vehicle, which comprises an outer sleeve, a steering damper shaft, a wheel fixing shaft, a steering arm and a steering arm connecting tube. The steering damper shaft is arranged in the outer sleeve; a circumferential projecting part is arranged on the steering damper shaft; a torque transmitter is arranged on the projecting part; the wheel fixing shaft is fixed onto the steering damper shaft; the steering arm is fixed onto the steering arm connecting tube; the steering arm connecting tube is sleeved on the steering damper shaft; a torque receiver is arranged on the end face of the steering arm connecting tube and matched with the torque transmitter; threads are arranged at the end of the steering damper shaft; and the steering arm connecting tube is fastened by a nut after being sleeved on the steering damper shaft. The front axle damper has the advantages that the steering arm connecting tube is capable of rotating by tightening or loosening the nut, so that the angle between the steering arm and the steering damper shaft is adjusted, adjustment in optional angles can be realized, and materials, time and production cost are saved.
Description
Technical field
The utility model belongs to electric automobiles, the damping of especially a kind of four-wheel electric motor car propons.
Background technology
At present, four-wheel electric motor car propons spindle arm all adopts cast steel or steel directly to be welded on the damping steering shaft both at home and abroad, and the angle of spindle arm and wheel anchor shaft is nonadjustable; Vehicle is different, and the wheelspan of wheel is different, therefore; The angle of spindle arm is also different, cannot be general, change angle if desired; Must make the cast steel mould again, perhaps change welding tooling, this will inevitably cause material and waste of time.
Summary of the invention
The utility model is to the four-wheel electric motor car propons spindle arm that exists in the above-mentioned technology and the uncontrollable shortcoming of angle of wheel anchor shaft; The damping of a kind of four-wheel electric motor car propons is proposed; It has and can spindle arm and wheel anchor shaft be carried out the function that multi-angle is regulated; Can carry out angular adjustment according to the applicable cases and the needs of reality, reach best result of use.
The technical scheme that realizes the utility model purpose is following:
The damping of four-wheel electric motor car propons, it comprises outer tube, turns to elastic axis, wheel anchor shaft, spindle arm, spindle arm connection pipe, turns to elastic axis to be located in the outer tube; Turn to elastic axis to be provided with the projecting member of hoop, this projecting member is provided with the moment of torsion converyer, and the wheel anchor shaft is fixed on and turns on the elastic axis; Spindle arm is fixed on the spindle arm connection pipe; The spindle arm connection pipe is set in and turns on the elastic axis, and spindle arm connection pipe end face is provided with the moment of torsion receptor, and the moment of torsion converyer cooperates with the moment of torsion receptor; End turning to elastic axis is provided with screw thread, and the spindle arm connection pipe is fastening through nut after being set in and turning on the elastic axis.
Described moment of torsion converyer and moment of torsion receptor are spline.
Described moment of torsion converyer and moment of torsion receptor are the sudden strain of a muscle tooth that cooperatively interacts.
The utility model has the advantages that through the nut degree of tightness to let the spindle arm connection pipe rotate setting, thereby regulate spindle arm and turn to the angle between the elastic axis, can arbitrarily angledly regulate saving in material, time, productive costs.

Fig. 2 is the structural representation that turns to elastic axis;
Fig. 3 is the structural representation of spindle arm connection pipe.
The specific embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, the damping of four-wheel electric motor car propons, it comprises outer tube 1, turns to elastic axis 2, wheel anchor shaft 3, spindle arm 6, spindle arm connection pipe 4; Turn to elastic axis 2 to be located in the outer tube 1; Turn to elastic axis 2 to be provided with the projecting member 2a of hoop, this projecting member 2a is provided with the moment of torsion converyer, and wheel anchor shaft 3 is fixed on and turns on the elastic axis 2; Spindle arm 6 is fixed on the spindle arm connection pipe 4; Spindle arm connection pipe 4 is set in and turns on the elastic axis 2, and spindle arm connection pipe 4 end faces are provided with the moment of torsion receptor, and the moment of torsion converyer cooperates with the moment of torsion receptor; End turning to elastic axis is provided with screw thread, and the spindle arm connection pipe is fastening through nut 5 after being set in and turning on the elastic axis.
Described moment of torsion converyer and moment of torsion receptor are spline.
Perhaps, described moment of torsion converyer and moment of torsion receptor are the sudden strain of a muscle tooth that cooperatively interacts.
