In order to ensure the driving safety, the maximum steering angle of the motorcycle needs to be limited, otherwise, the motorcycle is suddenly steered at a large angle in an emergency, and the vehicle can overturn, so that safety accidents are caused.
To define the maximum steering angle, the following is generally used: a limiting block is arranged on the front sleeve of the frame, two limiting bulges which are symmetrical relative to the limiting block in a straight-ahead state are arranged on the lower connecting plate, the two limiting bulges rotate along with the rotation of the direction column, and when the limiting bulges rotate to be in contact with the limiting block on the sleeve, the limiting bulges can not rotate any more; or the front shock absorber is sleeved with a limiting rubber sleeve at a position corresponding to the vehicle frames at the two sides of the front sleeve, the cross section of the limiting rubber sleeve is in a cam shape, and the steering is carried out until the protruding end of the limiting rubber sleeve abuts against the vehicle frames to form the maximum steering angle.
However, the following technical problems exist: 1. the distances between the two limiting bulges on the lower connecting plate of different vehicle types are different, and the stamping and casting dies are increased due to the fact that different vehicle types are processed; the limiting rubber sleeve also needs to be designed and manufactured according to different shock absorbers and the maximum steering angle, so that the production cost is increased; 2. the maximum steering angle of the motorcycle is generally preset and fixed, and a user cannot adjust the maximum steering angle according to the self condition, so that the flexibility is poor; the limit rubber sleeve causes the increase of the parts of the shock absorber, and the assembly is more complicated; 3. when the front wheel receives great impact deviation in the driving process, the two limiting protrusions on the lower connecting plate collide with the limiting blocks on the front sleeve quickly, the limiting protrusions and the limiting blocks are easily abraded or damaged, and later maintenance is difficult.
The applicant designs a steering mechanism for a motorcycle, please refer to chinese patent CN202021518136.9, a limit washer is fixedly arranged on the upper portion of a steering column, and a first limit block and a second limit block on the limit washer respectively abut against a protrusion on a sleeve, so as to limit the rotation angle of the steering column. The limiting washer can be replaced according to requirements to adjust the steering mechanism, so that the production cost is reduced, and later maintenance is facilitated; however, the main function of the steering mechanism is to reduce the vertical impact on the front shock absorber caused by the impact force on the front wheel, so as to prolong the service life of the front shock absorber, and meanwhile, the installation of related components on the upper part of the steering column can cause the assembly difficulty to increase.
