The utility model also provides an operating method of university student's equation motorcycle race stabilizer system, it specifically includes following step:
working condition 1: when the racing car is in the steering condition
As shown in fig. 6, if the racing car turns right (left and right based on the viewing angle of the rider), the left tire jumps up, the right tire jumps down, and the vehicle body rolls. Jump-up of the left tire. Through the motion transmission of a suspension push rod 21, a suspension rocker arm 1, a stop bolt 2 and a transverse stabilizer bar pull rod 22, one end of a transverse stabilizer bar bent rod 9 is subjected to thrust; the left tire also moves through the suspension push rod 21, the suspension rocker arm 1, the tucking bolt 2 and the stabilizer link 22, so that the other end of the stabilizer link 9 is pulled.
Since the stabilizer bar knee 9 is fixed to the frame by the knee mount 6 and the knee mount 7, there is only one rotational degree of freedom and no translational degree of freedom. Therefore, when the racing car turns right, the stabilizer bar bent rod 9 is deformed by a force, thereby providing a force against the left tire jumping up and the right tire jumping down, and suppressing the roll of the car body. This action is consistent with that of the prior stabilizer bar.
Working condition 2: when the racing car is in the acceleration condition
As shown in fig. 7, the racing rear-suspension left and right tires jump up simultaneously due to load transfer, and both ends of the stabilizer bar bent rod 9 receive thrust through the motion transmission of the suspension push rod 21, the suspension rocker arm 1, the tucking bolt 2, and the stabilizer bar link 22. Because the stabilizer bar bent rod 9 is fixed on the frame and has a rotational degree of freedom, the stabilizer bar bent rod 9 can drive the bent rod mounting seat 6 to rotate under the action of the bearing, and resistance force resisting bending is not generated, so that the stabilizer bar 9 does not provide roll rigidity under the acceleration working condition.
Working condition 3: when the racing car is in the braking condition
As shown in fig. 8, the rear overhang left and right side tires of the racing car simultaneously bounce due to load transfer. Through the motion transmission of the suspension push rod 21, the suspension rocker arm 1, the tucking bolt 2 and the transverse stabilizer bar pull rod 22, the two ends of the transverse stabilizer bar bent rod 9 are subjected to pulling force. Because the stabilizer bar bent rod 9 is fixed on the frame through the bent rod mounting seat 6 and has a rotational degree of freedom, the stabilizer bar bent rod 9 can drive the bent rod mounting seat 6 to rotate under the action of a bearing, and no resistance force for resisting bending is generated, so that the stabilizer bar does not provide roll rigidity under the acceleration working condition.
