（産業上の利用分野）
本考案は、自動二輪車における後車輪支持装

のである。[Detailed Description of the Invention] (Field of Industrial Application) The present invention is intended for use in a rear wheel support device for a motorcycle, particularly in a suspension system that supports the rear wheel with a single shock absorber. This invention relates to a support device that can prevent climbing.
（従来技術）

する際に生じる後車輪の動きと、緩衝器の動きと
は１対１の比例関係にある。即ち後輪が２cm上下
すれば、緩衝器もそれにともない２cm上下する。(Prior Art) Rear wheel shock absorbers for motorcycles are usually supported at the lower part of the vehicle body frame, and are supported in pairs on the left and right between a swing arm that pivotally supports the rear wheel and a rear upper portion of the vehicle body frame. Therefore, there is a one-to-one proportional relationship between the movement of the rear wheels and the movement of the shock absorber that occurs when driving on an uneven road surface. In other words, if the rear wheel moves up or down by 2cm, the shock absorber also moves up or down by 2cm.

れ、前のめりになることがあつた。 This sometimes gave the rider an unpleasant shock, so the two shock absorbers mentioned above were combined into one.
In addition, by supporting the rear wheel with this shock absorber between the vehicle body frame and the swing arm via a bell crank and a push rod, the amount of increase in the buffer force of the shock absorber can be increased more than the amount of rocking of the swing arm, A rear wheel suspension system has been devised in which the movement of the rear wheel and shock absorber is progressive. (Refer to Japanese Patent Application Laid-open No. 103679/1983) This increased the buffering force of the shock absorber against the swinging amount of the swing arm and improved the unpleasant shock to the rider, but it also caused the movement of the center of gravity of the vehicle during braking and the inertia. Due to force, etc., the rear body of the vehicle would rise and the front wheels would sink, which combined to cause the vehicle to lean forward.
特に、自動二輪車の場合、前後輪に与える制動

サー等において、急制動時における影響は、一層
大きい。 In particular, in the case of a motorcycle, the braking force applied to the front and rear wheels is greater than that of the front wheels, so that the front wheel sinks and the rear wheel lifts up. Furthermore, in racers and the like, the effect is even greater during sudden braking.

しようとするものである。(Purpose of the invention) The present invention was devised to eliminate the above-mentioned drawbacks, and utilizes a structure in which the rear wheel is supported by a shock absorber between the vehicle body frame and the swing arm via a bell crank and a push rod. By using the reaction force to push up the shock absorber, the front body of the vehicle is prevented from sinking, and the entire body of the vehicle is prevented from lifting up.

This figure is a partial perspective view showing the main parts. 1 is a vehicle body frame, and 2 is a swing arm, which is pivotally supported by left and right gussets 3 fixed to the vehicle body frame 1. 4 is its supporting axis. 5 is an axle for supporting the rear wheel 6 at the other end of the swing arm 2. 7 is a disc plate integrally fixed to the axle 6, and 8 is a caliper having built-in pads for clamping the disc plate 7 and applying braking force, and is rotatably supported on the axle 5. Reference numeral 9 denotes a shock absorber, which is rotatably supported by the vehicle body frame 1 at its upper end and by the bell crank 10 at its lower end. The bell crank 10 has a substantially triangular shape; one end is connected to the vehicle body frame 1 via a bracket 11, the other end is connected to the shock absorber 9, and a torque rod 12 for connecting to the caliper 8 is rotatable at the lower center of the bell crank 10. It is freely pivoted. 13
is a push rod for connecting the swing arm 2 and the bell crank 10, and is rotatably supported by each of the push rods.

A force that pulls the rear wheel 6 toward the ground surface acts on the rear wheel 6, as indicated by F1 in FIG. Since the caliper 8 is rotatably supported on the axle 5, the torque rod 12
is pulled in the direction of the arrow, and a force acts to rotate the bell crank 10 about the support shaft of the bracket 11 in the direction of the arrow in the figure. Then, a force F 2 acts on the push rod 13, and a force F 3 acts on the swing arm 2 via the support shaft 4 to lift the vehicle body. On the other hand, a force F 4 that tends to lift the vehicle body similarly acts on the shock absorber 9 that is pivotally supported at the other end of the bell crank 10.

止する。 As described above, when a braking force is applied to the rear wheel 6, the force F1 that pulls the rear wheel 6 toward the ground contact side is applied, and at the same time, the force F1 is applied to the swing arm 2 via the torque rod 12, bell crank 10, and push rod 13.
Forces that try to push up the vehicle body of F 3 and F 4 act on the shock absorber 9, respectively, to keep the motorcycle body horizontal at all times and prevent the rider from leaning forward.

This makes it possible to reliably prevent the rear part of the car body from lifting up, and at the same time prevent the front part of the car body from sinking, making it possible to maintain the level of the car body at all times.
なお上記の説明で、制動装置はデイスクブレー
キを例にとり説明したが、ドラムブレーキにも適
用できることは、いうまでもない。 In the above description, the braking device has been explained using a disc brake as an example, but it goes without saying that the braking device can also be applied to a drum brake.
またベルクランクは三角形に限定するものでは
なくいずれの形状であつてもよい。 Further, the bell crank is not limited to a triangular shape, and may have any shape.
