The utility model content
The purpose of this utility model just provides a kind of preventing from the regular three-wheeled motor vehicle carriage of stopping.
The purpose of this utility model is to realize by such technical scheme, a kind of regular three-wheeled motor vehicle carriage, comprise longitudinal edge beam, link span and be arranged on the grasswort steel spring of longitudinal edge beam below, be respectively arranged with front frame and after poppet in the anterior side of longitudinal edge beam and the lower surface at rear portion, one end of described grasswort steel spring is connected with front frame, and the other end is connected with after poppet by the hanger that is movably arranged on the after poppet.Described front frame comprises that an end is welded on two front frame plates of the inside and outside both sides of longitudinal edge beam respectively, be welded with the front frame brace panel that connects two front frame plates two front frame plate lower inside, be respectively arranged with front frame plate axle sleeve two front frame plate bottoms, described front frame plate is stepped, and the front frame plate is provided with the boss that is one with the front frame plate.Do the effect that makes front frame play power transmission and guiding like this, and have the functional characteristic of reinforced rib, after poppet and hanger be arranged so that it can make the distance of the two ends centreline space of back axle grasswort steel spring do corresponding change when spring deflection.
In order to limit the maximum distortion of back axle grasswort steel spring, and prevent the longitudinal edge beam of back axle grasswort steel spring direct impact vehicle frame, upper surface at grasswort steel spring middle part is provided with damping rubber block, and the pairing longitudinal edge beam of damping rubber block lower surface is provided with limiting stopper.
Described longitudinal edge beam can be to be provided with like this: longitudinal edge beam anterior S-type, and a described S-type end is connected with the link span bottom, and described front frame is obliquely installed turning on the S of longitudinal edge beam type.
Certainly, also can be to be provided with like this: described longitudinal edge beam comprises longitudinal edge beam body, and described longitudinal edge beam body is rectangular tube always, and the one end is connected with link span top; Described longitudinal edge beam also comprises L shaped strut member, and an end of described L shaped strut member is connected with the link span bottom, and the front portion of the other end and longitudinal edge beam is connected to form the S type, and described front frame is vertically set on L type strut member and longitudinal edge beam junction.
Owing to adopted technique scheme, the utility model not only has advantage simple in structure, that load-carrying capacity is strong, but also has following advantage:
1. front frame and after poppet are separately positioned on the lower surface at anterior side and rear portion, actv. has increased the vehicle frame transverse width, alleviated load-carrying requirement to back axle, make vehicle under heavily loaded situation, back axle drum-type wheel cam speculum can not produce open phenomenon, has avoided occurring in the process of moving the generation of motor tricycle self-actuating brake defective.
2. front frame and after poppet are separately positioned on the lower surface at anterior side and rear portion, have reduced the manufacturing procedure to the boring of longitudinal edge beam, have saved working time, have improved labor efficiency.
3. the setting of damping rubber block and limiting stopper has limited the maximum distortion of back axle grasswort steel spring, and has prevented the longitudinal edge beam of back axle grasswort steel spring direct impact vehicle frame.
4. the longitudinal edge beam is S-type, has increased the load-carrying capacity of vehicle frame.
