Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, 2 and 3, it can be seen from the drawings that the front and rear linkage brake mechanism of the motorcycle of the present invention comprises a front brake handle 1, a front brake 2, a rear brake arm 3 and a rear brake 4, wherein the front brake handle 1 is connected with the front brake 2 through a front transmission mechanism, the rear brake arm 3 is rotatably mounted on the frame through a brake arm rotating shaft, one end of the rear brake arm 3 is connected with the rear brake 4 through a rear transmission mechanism, and the other end of the rear brake arm 3 is provided with a brake pedal 5. According to the difference of drum brake and disc brake, the transmission principle and structure of front and back transmission mechanism are also different. In order to realize linkage braking of the front wheel and the rear wheel, the structure is provided with a rotatable roller 6 and a rear braking cable 7 on a vehicle body through a transverse roller rotating shaft 14, the rear end of the rear braking cable 7 is connected to the rear braking arm 3, and the front end of the rear braking cable bypasses the roller 6 to change the direction and is connected with a front transmission mechanism. The roller 6 corresponds to a fixed pulley, which is fixed in position but rotatable, for changing the direction of force. In practical design, the roller 6 is mounted on the rear fork assembly 8 through the roller rotating shaft 14. When the rear brake arm 3 is trodden to brake the rear wheel, the rear brake arm 3 rotates around the rotating shaft, and the rear brake arm drives the rear brake to act through the rear transmission mechanism, so that the rear wheel brake is realized. When the rear brake arm 3 rotates, the rear brake cable 7 is driven to act, the rear brake cable 7 further drives the front transmission mechanism to act, and the front transmission mechanism drives the front brake 2 to act, so that the front wheel brake is realized. The principle of front wheel braking during linkage braking of the structure is similar to the principle of independent braking of the existing front brake handle, only one front transmission mechanism is driven to act by the stay cable, the traditional method is that the front brake handle drives the front transmission mechanism to act, the principle of action of the stay cable and the front brake handle on the front transmission mechanism is the same, the connection of the front transmission mechanism and the front brake is completely the same as that of the existing structure, and only one more object (namely the stay cable) for applying acting force on the front transmission mechanism is provided.
Under normal construction, the front brake handle 1 is located between the upper handle mounting seat 9 and the lower handle mounting seat 10. In order to better realize the effect of the rear brake cable on the front transmission mechanism, a linkage trigger handle 11 is further arranged between an upper handle mounting seat 9 and a lower handle mounting seat 10, referring to fig. 3, a front brake handle 1 and the linkage trigger handle 11 are arranged up and down and rotatably connected between the upper handle mounting seat 9 and the lower handle mounting seat 10 through a same vertical handle rotating shaft 24, and a torsion spring 25 for enabling the front brake handle to automatically return is arranged on the handle rotating shaft 24; the front end of the rear brake cable 7 is connected with the front transmission mechanism through a linkage trigger handle 11. Although called a linkage brake handle, the brake handle cannot be manually held and controlled per se, but only compared with a front brake handle. The linkage trigger handle is arranged, so that the braking principle in linkage is completely the same as that of a traditional front brake handle, only the traditional front brake handle is operated by hands to rotate for a certain angle, and in linkage braking, the linkage trigger handle is pulled by the inhaul cable to rotate for a certain angle, and the action of the linkage trigger handle on the front transmission mechanism after rotating for a certain angle is completely the same as that of the front brake handle on the front transmission mechanism after rotating for a certain angle. If the rear brake cable is directly connected with the front brake handle, linkage braking can be realized, but the front brake handle can automatically rotate by a certain angle, and an operator does not manually act on the front brake handle at the moment, so that the driving feeling and the operation habit of a driver can be influenced, and the safety driving is influenced. In view of this, this structure has additionally set up the linkage trigger handle, plays the effect when the linkage braking of rear wheel and front wheel are braked alone respectively by linkage trigger handle and preceding brake handle to do not influence driving impression and custom at all.
Bosses are formed on the front brake handle 1 and the linkage trigger handle 11 around the handle rotating shaft, so that gaps which are beneficial to rotation are formed between the front brake handle and the linkage trigger handle, between the front brake handle and the upper handle mounting seat and between the linkage trigger handle and the lower handle mounting seat. Through the arrangement of the lug boss, the rotation of the front brake handle and the linkage trigger handle are not influenced mutually, and the front brake handle and the linkage trigger handle can rotate independently and reliably.
In order to make the rotation of the roller more flexible and thus not affect the acting force when the rear brake is trampled, the structure is provided with a bearing 12 and a bearing lining pipe 13 between the roller 6 and a roller rotating shaft 14, the bearing lining pipe 13 is directly sleeved on the roller rotating shaft 14, the bearing 12 is positioned between the roller 6 and the bearing lining pipe 13, and oil seal structures 15 are arranged at two ends of the bearing on the roller rotating shaft 14; a roller return torsion spring 16 for automatically returning the roller is provided on the roller shaft 14, see fig. 2.
The outer side of the roller 6 is provided with a protective plate 17, and the protective plate 17 is arranged on the roller rotating shaft 14 and shields the roller 6. The protection plate can enough shelter from earth, dust and the like and get into the gyro wheel, also can avoid the gyro wheel of motion to expose and touch the person or the clothing and bring potential safety hidden danger, and after the gyro wheel was sheltered from to the protection plate simultaneously, whole car commodity nature was better, was accepted by the consumer more easily.
When the brake pedal is arranged, the idler wheel is arranged between the rear brake and the brake arm rotating shaft, and the rear end of the rear brake cable is connected to the rear brake arm and is positioned on the other arm of force opposite to the arm of force where the brake pedal is positioned.
The motorcycle brake mode that this linkage brake mechanism aims at is preceding dish rear drum, and the front wheel braking is the dish and stops promptly, and the rear wheel braking is the drum and stops, see figure 1, and preceding drive mechanism includes piston 18, preceding braking main pump 19 and preceding brake oil pipe 20 this moment, and the handle promotes piston 18 to make the fluid of preceding braking main pump 19 get into in preceding brake oil pipe 20, and then promote preceding brake caliper 21 by fluid and hold the preceding brake disc 22 tightly and can brake. The main body of the rear transmission mechanism is a rear brake pull rod 23, the front end of the rear brake pull rod 23 is connected with the rear brake arm 3, the rear end of the rear brake pull rod 23 is connected with the rear brake 4, and a return spring for returning the rear brake pedal is arranged between the rear brake pull rod and the rear fork assembly. The rear brake arm rotates to enable the rear brake pull rod to move forwards, and then the rear brake is driven to brake. The linkage mechanism involved in linkage braking is divided into an upper linkage mechanism taking a linkage braking handle as a main part and a lower linkage mechanism taking a roller as a main part, and the upper linkage mechanism and the lower linkage mechanism are connected through an additional rear braking inhaul cable. The upper linkage mechanism is integrated with a front brake main pump assembly, and the front brake main pump is generally fixed on a handle of the motorcycle.
The lower linkage mechanism is also a single mechanism, which is assembled near the rear brake arm, connected with the front and rear linkage mechanisms through a rear brake cable, and fixed on the rear brake arm.
The working principle is as follows: when the rear wheel is braked by the rear brake pedal, the upper and lower linkage devices are driven by the steel wire rope in the rear brake cable to fulfill the aim of front wheel braking. The specific operation is as follows:
when the rear brake pedal brakes according to an arrow in the figure (the force is less than or equal to 400N), the rear brake arm rotates, a rear brake pull rod connected with the rear brake arm transmits acting force to the rear brake to brake the rear wheel, meanwhile, a rear brake cable on the rear brake arm moves according to the arrow in the figure, a steel wire of the rear brake cable is driven through a roller, the rear brake cable is connected with a linkage brake handle at the front disc brake pump, and the linkage brake handle rotates for a certain angle under the pulling of the cable to push a piston to move (the principle of pushing the piston to move is completely the same as that of pushing the front brake handle), so that the purpose of front braking is achieved. Wherein both ends fixed department all has adjusting bolt around the back braking cable, and adjusting bolt's effect is arranged in adjusting the cable steel wire and exposes length, also is used for adjusting the size of braking force before simultaneously, prevents that the front wheel "locks", and the braking deceleration increases immediately, guarantees the personnel's of riding safety. The front brake pushes brake fluid in the main pump to form pressure through a piston in the front brake main pump, the pressure is transmitted to the front brake caliper through a brake oil pipe, and the front brake disc is braked through the piston in the caliper.
