Abstract
The invention belongs to the field of electric vehicles and in particular discloses a four-wheel electric vehicle front axle damper. The four-wheel electric vehicle front axle damper comprises an outer sleeve, a steering damping shaft, a wheel fixing shaft, a steering arm and a steering arm connecting pipe, wherein the steering damping shaft is arranged in the outer sleeve; an annular protruding part is arranged on the steering damping shaft; a torque transmitter is arranged on the protruding part; the wheel fixing shaft is fixed on the steering damping shaft; the steering arm is fixed on the steering arm connecting pipe; the steering arm connecting pipe is sleeved on the steering damping shaft; a torque receiver is arranged on the end face of the steering arm connecting pipe; the torque transmitter is matched with the torque receiver; a thread is formed at the end of the steering damping shaft; and the steering arm connecting pipe is sleeved on the steering damping shaft and is fastened through a nut. The four-wheel electric vehicle front axle damper has the advantages that due to the tightness of the nut, the steering arm connecting pipe can be rotationally arranged, so that the angle between the steering arm and the steering damping shaft is adjusted, the angle can be optionally adjusted, and the materials, time and production cost are saved.
Description
Technical field
The invention 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 present invention is directed 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 object of the invention 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.
Advantage of the present invention is can let the spindle arm connection pipe rotate setting through the nut degree of tightness, thereby regulates spindle arm and turn to the angle between the elastic axis, can arbitrarily angledly regulate saving in material, time, productive costs.
Description of drawings
Fig. 1 is a structural representation of the present invention;
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
As shown in Figure 1, 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.
