Problems solved by technology
[0005] Since the driving sprocket 106 is arranged on the output shaft 102 and is located outside the first coupling section 123 of the first supporting portion 121, the driven sprocket 107 and the rear sprocket 107 that cooperate with the driving sprocket 106 The distance between the wheels 109 increases, which also increases the length of the rear axle 104, and makes the first connecting section 125 appear to be inclined and bent towards the first pivoting section 124, so that the motorcycle The volume and weight of the car 100 are greatly increased; the rear axle 104 is more likely to decrease in structural strength due to its excessive length, which in turn affects the service life of the motorcycle 100; The distance between the driving sprocket 106 and the driven sprocket 107 is increased to generate a larger moment on the rear wheel shaft 104, so that the rear wheel 109 is easy to shift during operation, which affects the stability of the motorcycle 100.

The invention relates to a motorcycle rear rocker device. The power unit of a motorcycle comprises a transmission case, a transmission shaft penetrating through the transmission case, a rear wheel which is apart from the transmission shaft and has a rear wheel axle and a driving unit, wherein the driving unit comprises a drive wheel arranged on the transmission shaft and a driven wheel arranged on the rear wheel axle. The rear rocker device comprises a combining unit arranged on the transmission case and a rocker arranged on the combining unit, wherein the rocker comprises a first support part and a second support part which are sleeved on the combining unit at intervals; the drive wheel is arranged between the first support part and the transmission case, thus effectively reducing the distance between the drive wheel and the transmission case, the distance between the driven wheel and the rear wheel and the length of the rear wheel axle, lowering the volume and weight of the motorcycle and prolonging the service life of the motorcycle.
Description
【Technical field】 [0001] The invention relates to a rear rocker arm device, in particular to a rear rocker arm device of a motorcycle. 【Background technique】 [0002] refer to figure 1 , the existing rocker arm supporting structure 1 is pivotally arranged on a motorcycle 100, and the motorcycle 100 includes a transmission box 101, an output shaft 102 pivotally passed through the transmission box 101, and an output shaft 102 arranged on the output shaft. The driving unit 103 of the upper 102, the rear wheel shaft 104 pivotally arranged on the rocker support structure 1 at a distance from the transmission case 101, the rear wheel 109 arranged on the rear wheel shaft 104, and the output shaft can be driven 102 rotating engine (not shown), the driving unit 103 includes a driving sprocket 106 arranged on the output shaft 102 and outside the rocker support structure 1, a passive chain arranged on the rear axle 104 Wheel 107, and a chain 108 wrapped around the driving sprocket 10...
