Description

Motorcycle linkage brake device

technical field

The invention relates to a motorcycle brake device, in particular to a motorcycle linkage brake device.

Background technique

Existing motorcycles usually use hand-controlled front wheel brakes and feet to control rear wheel brake structures, but research on human psychology and physiology has shown that in emergency situations, people tend to subconsciously "use both hands and feet", while human exercise physiology and human factors Engineering studies have shown that the movement speed of the hands is 1.5 to 3 times that of the feet, so the actual result of the "hands and feet" braking action on the motorcycle is that the front wheel brakes are earlier than the rear wheel brakes, which causes the motorcycle to overturn. As for people In an emergency situation, it is not uncommon to cause the car to roll over due to nervousness and misoperation such as braking the front wheel first and then braking the rear wheel or only braking the front wheel (not using the foot to step on the rear wheel brake).

There are also people who use linkage brakes, such as Chinese utility model patent 94245827.3, which was authorized by announcement on April 10, 1996. A motorcycle brake structure includes a right hand handle, a front wheel brake cable, a pedal, a rear wheel brake cable, and its front The wheel brake backguy is divided into upper and lower sections of backguy, a backguy connecting plate is set between the upper and lower section of the backguy, and an intermediate brake backguy is connected between the backguy connecting plate and the pedal. Another example is Chinese utility model patent 99217787.1, which was authorized by announcement on October 11, 2000. It is a double-action motorcycle brake device. Only one pull rod is set on the motorcycle brake device, and a linkage is fixed on the pull rod. And between this linkage piece and the front stopper that controls the front wheel brake, a front guide cable is consolidated, and between the linkage piece and the rear stopper that controls the rear wheel brake, a rear guide cable is consolidated, so that the pull rod is controlled. When the linkage is pulled and driven to move, the front stopper and the rear stopper can be respectively pulled to produce braking actions on the front and rear wheels at the same time. The above two patents essentially use hard-connected components to achieve linkage. If the free strokes of the front and rear wheel brakes are inconsistent (in fact, it is difficult to achieve complete consistency), when one wheel is braked, the other wheel has not been braked. , the brake cable will be tightened and stuck, and the linkage brake will lose its meaning; in addition, the above two patents do not consider the order of the front wheel brake and the rear wheel brake, and cannot effectively solve the problem of braking the front wheel first and then the rear wheel. safety performance issues.

Contents of the invention

The technical problem to be solved by the present invention is to provide a motorcycle linkage braking device with good linkage braking effect and good safety performance. No matter whether it is the hand-first action or the foot-first action, the first brake is always the rear wheel, thereby completely avoiding the brake malfunction. Occurs, eliminating the hidden danger of tipping due to misoperation.

In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions: a motorcycle linkage braking device, comprising front wheel brakes, front wheel brake wire ropes, pedal swing bars, pull rods, pedals, rear wheel brakes, Connecting rod, manual swing rod, rear wheel brake wire rope, handle, the pedal swing rod is provided with a pivot point, one end of the front wheel brake wire rope is connected with the front wheel brake, and the front wheel brake wire rope The other end is connected with one end of the pedal swing rod, the other end of the pedal swing rod is connected with one end of the pull rod, the other end of the pull rod is connected with the pedal, one end of the manual swing rod is provided with a pivot point, and the manual swing rod The other end is connected with one end of the rear wheel brake wire rope, the other end of the rear wheel brake wire rope is connected with the handle, one end of the connecting rod is connected with the rear wheel brake, and the other end of the connecting rod is connected with the swing end of the manual swing lever. Connected, a linkage elastic connector is provided between the pedal swing lever and the manual swing lever, and the front wheel brake reserves a certain amount of air travel for the front and rear wheel differential brakes.

The linked elastic connector can be set to: include a distance-adjusting pull rod and a compression spring, the upper end of the distance-adjusting pull rod is connected with the pull-rod connection end of the pedal swing rod, the swing end of the manual swing rod is provided with a through hole, and the distance-adjusting pull rod The lower end passes through the through hole of the manual fork and stretches out the below of the manual fork, and a compression spring is provided between the lower end of the distance adjustment pull bar and the manual fork.

The linkage elastic connector can also be set to: include a distance adjustment rod and a tension spring, the upper end of the distance adjustment rod is connected with the pull rod connection end of the pedal swing rod, one end of the tension spring is connected with the lower end of the distance adjustment rod, The other end of extension spring is connected with the swing end of manual swing lever.

The linkage elastic connector can also be a leaf spring or a torsion spring, one end of the leaf spring or torsion spring is connected to the tie rod connecting end of the pedal swing bar, and the other end of the leaf spring or torsion spring is located below the manual swing bar.

In the above-mentioned technical scheme, the manual control of the rear wheel brakes, because the movement of the hands is relatively fast, the braking action of controlling the rear wheel brakes with hands is obviously faster than that of controlling the rear wheel brakes with feet, so the safety of emergency braking can be improved; There is a linkage elastic connecting piece between the pedal swing lever and the manual swing lever. When the pedal swing lever rotates, the spring in the linkage elastic connection piece drives the manual swing lever to rotate, so as to control the action of the rear wheel brake in linkage. Because the spring is elastic, Even after the rear wheel is braked, the pedal swing lever can still continue to swing until the front wheel is completely braked. Therefore, it can avoid the problem in the prior art that the linkage brake will lose its effect because the brake cable is tightened and stuck. Linkage braking effect; and because the front wheel brakes reserve a certain space for front and rear wheel differential braking, no matter whether it is hand-first action or foot-first action, the first brake is always the rear wheel, so it can completely avoid the occurrence of brake misoperation and eliminate The hidden danger of tipping due to misoperation is eliminated.
