Abstract
The utility model relates to a tricycle braking device, particularly a hand brake lever and handle brake joint operation device of the tricycle, which comprises a tricycle frame and a bell crank; a handle brake device which is composed of a short draw rod, the bell crank, a telescopic buffer of the draw rod and a brake draw rod, and a hand brake device which is composed of a brake handle, a connection pile of a draw rod and a brake draw rod are arranged on the tricycle frame; a one-way telescopic connection is adopted between the telescopic buffer of the draw rod and the brake draw rod, and between the connection pile of the draw rod and the brake draw rod. The utility model has the advantages of simple structure, flexible and reliable action and good brake effect and is an ideal hand brake lever and handle brake joint operation device for the tricycle.
Description
The utility model relates to a kind of three-wheel vehicle braking device, relates in particular to a kind of three-wheel vehicle parking brake, the linkage braking device of stopping.
At present, the pattern of three-wheel vehicle braking has two kinds: the brake handle on braking (calling in the following text stopping) or the vehicle frame on the handlebar is braked (calling parking brake in the following text).Is the advantage of stopping flexible and convenient operation, and the glancing impact hand does not leave handlebar, is swift in response, and does not influence posture by bike, safer by bike.Shortcoming is that deceleration and stopping performance is not ideal enough under the car loading condition, is difficult to reach the loaded vehicle downhill braking, the requirement of the big braking force that the quick emergency brake of loaded vehicle etc. are required.Used on medium-sized load-carrying three-wheel vehicle and parking brake is common with its big braking force, follow one's bent but its operation can not resemble an instant sample, and when operation, a hand leaves handlebar, makes singlehanded handle, and handlebar control is unstable, and safety is relatively poor.
The purpose of this utility model is to provide a kind of deceleration and stopping performance good, has stopping with the three-wheel vehicle parking brake of two kinds of braking functions of parking brake, the linkage braking device of stopping.
The utility model is a kind of three-wheel vehicle parking brake, the linkage braking device of stopping, comprise vehicle frame, by short rod, crank throw, bracket arm form brake apparatus or by brake handle, the hand brake device that bracket arm, crank throw are formed.Its innovative point is and will brake apparatus and hand brake device be installed on the vehicle frame simultaneously, between brake handle and bracket arm pull bar is housed and is connected stake, and the flexible energy disperser of pull bar is housed between crank throw and bracket arm.Pull bar connects stake and bracket arm, all adopts unidirectional flexible the connection between the flexible energy disperser of pull bar and the bracket arm.
After the utility model adopted said structure, glancing impact just can be selected parking brake or as required braking.Simultaneously, because pull bar energy disperser and bracket arm, pull bar connects between stake and the bracket arm and all adopts unidirectional flexible the connection, thereby during when parking brake or braking, mechanism can not produce interference each other, has stopping and the mutual independence of parking brake and the conformability of braking effect.
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
Fig. 1 is the utility model integral structure scheme drawing;
Fig. 2 is the utility model A-A cutaway view Amplified image;
Fig. 3 is the utility model B-B cutaway view Amplified image.
The utility model mainly by hand brake device with brake apparatus two parts are formed, as shown in Figure 1, all be installed on the vehicle frame 7, hand brake device is by brake handle 9, pull bar connects stake 4 and bracket arm 6 compositions, links by crank throw 8 and rear wheel brake.Brake apparatus is made up of short rod 1, crank throw 2, the flexible energy disperser 3 of pull bar and bracket arm 5. link by crank throw 8 and rear wheel brake, wherein short rod 1 other end leads to three-wheel vehicle stopping handle.
Can adopt unidirectional flexible the connection between the flexible energy disperser 3 of pull bar and the bracket arm 5.As shown in Figure 2, have dead slot 10 and hole 11 in the flexible energy disperser 3 of pull bar, bracket arm 5 diameters are less than hole 11, but link the end diameter greater than hole 11 with the flexible energy disperser 3 of pull bar, thereby bracket arm 5 can be moved in dead slot 10, but can't skid off in hole 11.
Pull bar connects between stake 4 and the bracket arm 6 and also adopts unidirectional flexible the connection.As shown in Figure 3, in connecting stake 4, pull bar has hole 12, bracket arm 6 diameters are less than hole 12, have screw thread 13 at bracket arm 6 one ends, during connection, bracket arm 6 screw threads 13 ends pass hole 12, adopt nut 14 fixing then, thereby make the bracket arm 6 can be, but can't in hole 12, skid off to front stretching.
The utility model as required, can carry out parking brake or braking when practical operation.
When carrying out,,, drive short rod 1 by lever transmission with holding tightly the handle of stopping braking, crank throw 2, the pull bar energy disperser 3 that stretch, bracket arm 5, crank throw 8 etc., thus make the rear wheel brake action produce braking force, car is braked.
When carrying out the parking brake glancing impact, press brake handle 9, the pull bar connection stake 4 on the brake handle 9 makes bracket arm 6 follow brake handle 9 and moves together, and then drives crank throw 8 and rear wheel brake, makes the car braking.
The utility model is because flexible energy disperser 3 of pull bar and bracket arm 5, pull bar connects between stake 4 and the bracket arm 6 and all adopts unidirectional flexible the connection, so promptly guarantee the transmission of braking force and braking distance maximum with putting rate, make these two kinds of brake mode that the phenomenon that appropriate authority action is interfered mutually can not take place in braking procedure again, have stopping and the mutual independence of parking brake and the conformability of braking effect.
Certainly, the utility model as required, also can brake with a two-way linkage of stopping with carrying out parking brake, in the hope of reaching optimum braking effect when practical operation.
