AI Technical Summary

Technical Problem

The existing rear braking system of sidecar motorcycles has a brake cable that is too long, causing the main wheel and the side wheel to brake out of sync. This results in poor braking performance, increased braking distance, and the possibility of the motorcycle veering off course during emergency braking, posing a safety hazard.

Method used

A pulley block is used to replace the long-distance braking cable. The braking devices of the rear wheel and the side wheel of the main vehicle are connected by a linkage braking rocker arm and a pulley block to achieve synchronous braking. The pulley block is used to shorten the braking distance and improve the braking effect.

Benefits of technology

It solves the problems of poor braking feel and weak braking effect, and its structure is easy to adjust, improving maintainability and ensuring that the vehicle does not veer off course during emergency braking, thus improving safety.

[0002] The rear brake system of the existing small displacement side three-wheeled motorcycle basically adopts line-pulling drum brake, utilizes the rear brake pedal on the main vehicle, brakes the rear wheel of the main vehicle, and simultaneously brakes the wheels of the side bucket through an extended brake cable on the side bucket support. The long-distance brake linkage device makes the side wheel braking effect poor, prolongs the braking distance, and simultaneously causes the vehicle to deviate when the vehicle is braked in emergency, and when serious, causes the wear degree of the brake blocks of the rear wheel and the side wheel to be inconsistent, which leads to brake failure during braking, and causes serious safety hazards. SUMMARY

[0003] The utility model aims at providing a rear brake device of side three-wheeled motorcycle, and solves the problem of poor braking effect caused by the asynchronization of the brake of the main wheel and the side wheel due to the overlength of the brake cable.

[0004] Technical scheme: the rear brake device of side three-wheeled motorcycle, main vehicle rear brake device and side wheel brake device are respectively arranged on the main vehicle rear wheel and the side wheel, a brake pedal is connected with the main vehicle rear brake device, the main vehicle rear brake device and the side wheel brake device are connected through a brake cable, and the brake cable passes through a pulley block fixed on the side bucket support.

[0005] Further, the main vehicle rear wheel is also provided with a linkage brake rocker, the linkage brake rocker is a double-side brake rocker, a first brake cable and a second brake cable are respectively installed, the first brake cable is connected with the brake pedal, and the second brake cable is connected with the side wheel brake device.

[0006] Further, the linkage brake rocker includes two mounting holes, and is used for installing the first brake cable and the second brake cable.

[0007] Further, the pulley block includes three fixed pulleys on the side bucket support.

[0008] Further, the pulley block includes a first fixed pulley, a second fixed pulley and a third fixed pulley, the first fixed pulley is fixed on the side edge of the side bucket support close to the main vehicle rear wheel, the second fixed pulley is fixed on the front side of the side bucket support, and the third fixed pulley is fixed on the side edge of the side bucket support close to the side wheel.

[0009] Further, the main vehicle rear brake device is a drum brake device.

[0010] Further, the side wheel brake device is a drum brake device.

[0011] Beneficial effects: This utility model solves the shortcomings of poor braking feel and weak braking effect by replacing the existing braking method of using a long-distance braking steel cable with braking method of a pulley system. At the same time, this structure is easy to adjust and its maintainability is greatly improved. Attached Figure Description

[0013] Figure 2 This is a schematic diagram of the braking device for the rear wheels of the vehicle according to this utility model;

[0014] In the diagram: 1—Side wheel, 2—Side bucket support, 3—Main vehicle rear brake device, 4—Main vehicle rear wheel, 5—Brake pedal, 6—Main vehicle front wheel, 7—First fixed pulley, 8—Second fixed pulley, 9—Third fixed pulley, 101—First brake cable, 102—Second brake cable, 11—Side wheel brake device, 12—Linkage brake rocker arm. Detailed Implementation

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0016] like Figure 1 As shown, the sidecar motorcycle includes a sidecar support 2, a main vehicle front wheel 6, a main vehicle rear wheel 4, and a side wheel 1. The main vehicle rear brake device 3 and the side wheel brake device 11 are respectively installed on the main vehicle rear wheel 4 and the side wheel 1.

[0017] The main vehicle rear braking device 3 and the side wheel braking device 11 are drum brake devices; the main vehicle rear braking device 3 and the side wheel braking device 11 are connected by a second braking cable 102. The second braking cable 102 passes through the first fixed pulley 7, the second fixed pulley 8 and the third fixed pulley 9. The first fixed pulley 7, the second fixed pulley 8 and the third fixed pulley 9 are all fixed on the side bucket support 2. The first fixed pulley 7 is fixed on the side of the side bucket support 2 near the main vehicle, the second fixed pulley 8 is fixed on the front side of the side bucket support 2, and the third fixed pulley 9 is fixed on the side of the side bucket support 2 near the side wheel 1.

[0018] The rear wheel 4 of the main vehicle is also equipped with a linkage braking rocker arm 12. The linkage braking rocker arm 12 is a double-sided braking rocker arm with two mounting holes for mounting brake cables, one at the top and one at the bottom, for mounting the first brake cable 101 and the second brake cable 102 respectively. The first brake cable 101 is connected to the brake pedal 5.

[0019] When the brake pedal 5 is depressed, the first brake cable 101 drives the rear wheel 4 of the main vehicle to brake. At this time, the lower end of the linkage brake rocker arm 12 rotates forward around the axis, and through the lever principle, its upper end is driven to rotate backward around the axis, thereby driving the second brake cable 102 to drive the side wheel 1 to brake. Therefore, when braking is required, it is only necessary to depress the rear brake pedal 5, and the linkage brake rocker arm 12 simultaneously drives the rear wheel 4 and the side wheel 1 of the main vehicle to brake, achieving the effect of short braking distance and no deviation during emergency braking.
