Description

Technical Field

[0001] The utility model belongs to the technical field of motorcycles, and relates to a vehicle frame, in particular to a rear shock absorber vehicle frame of a motorcycle. Background Technique

[0002] A motorcycle vehicle frame generally includes a main frame and a rear swing arm. The rear swing arm can also be called a rear rocker arm. The rear swing arm connects the vehicle frame and the rear wheel, and transmits and bears the forces and torques of the vehicle frame and the rear wheel. The forces generated during vehicle acceleration, deceleration, and braking need to be conducted through the rear swing arm.

[0003] After retrieval, as disclosed in a Chinese patent document for a rear shock absorber structure of a motorcycle frame [Application No.: 202222157494.7; Publication No.: CN 217778879 U]. This rear shock absorber structure of the motorcycle frame includes a main frame and a rear swing arm. The rear swing arm is rotatably connected to the rear end of the main frame. A rear shock absorber is provided between the main frame and the rear swing arm. The main frame includes a main beam tube. A first shock absorber connection point is provided at the end of the main beam tube. The first end of the rear shock absorber is rotatably connected to the first shock absorber connection point. A shock absorber connection seat is provided on the rear swing arm. A second shock absorber connection point is provided on the shock absorber connection seat. The second end of the rear shock absorber is rotatably connected to the second shock absorber connection point. The position of the second shock absorber connection point is below the horizontal plane position of the rear swing arm. The advantage is that the height of the second shock absorber connection point is reduced, the distance between the first shock absorber connection point and the second shock absorber connection point is increased, and a longer rear shock absorber can be installed under the condition of the same vehicle frame size, so that the shock absorption effect of the motorcycle is better and the riding is more comfortable.

[0004] Although the first shock absorber connection point and the second shock absorber connection point disclosed in this patent reduce the height of the second shock absorber connection point and increase the distance between the first shock absorber connection point and the second shock absorber connection point, and a longer rear shock absorber can be installed under the condition of the same vehicle frame size, making the shock absorption effect of the motorcycle better and the riding more comfortable, however, the seat height cannot be adjusted according to the height of the customer.

[0010] With the above structure, by installing the adjusting seat and forming the first mounting hole and the second mounting hole in the adjusting seat, the rear shock absorber in the factory state is installed in the first mounting hole. When the customer is relatively short, the mounting bolt can be adjusted to the second mounting hole, so that the rear flat fork will be lifted a little, and relatively speaking, the seat height will be correspondingly reduced.

[0011] The upper main beam tube and the lower main beam tube are fixedly connected through a first fixed tube, and the included angle between the first fixed tube and the upper main beam tube is an acute angle.

[0012] With the above structure, by installing the first fixed tube, the connection and fixation between the upper main beam and the lower main beam are realized, making the connection more firm and the structure more stable.

[0013] Two connecting seats are fixed on the two side beam tubes, a support rod is rotatably connected to the connecting seat, and the two support rods are respectively rotatably connected to the rear tail fixing plate.

[0014] With the above structure, by installing the support rod, the rear tail fixing plate is supported, facilitating the adjustment and rotation of the position of the rear tail fixing plate.

[0015] A large cylinder is fixed at the upper end of the rear shock absorber, a small cylinder is fixed at the lower end of the rear shock absorber, two sliding grooves are formed in the inner wall of the large cylinder, two sliding blocks are fixed on the outer wall of the small cylinder, and the sliding blocks are slidably connected with the sliding grooves.

[0016] With the above structure, by installing the large cylinder and the small cylinder, the rear shock absorber is protected.

[0017] Compared with the prior art, the rear shock absorber frame of this motorcycle has the following advantages:

[0018] 1. By installing an adjustment seat, with the adjustment seat provided with a first mounting hole and a second mounting hole, the rear shock absorber in the factory state is installed in the first mounting hole. When the customer is relatively short, the mounting bolts can be adjusted to the second mounting hole. In this way, the rear fork will be lifted a little, and relatively speaking, the seat height will be correspondingly reduced.
