Abstract
The utility model relates to a hand brake parking device for tricycles, including a joystick, a fixed frame, a drive rod, a driven rod, a connecting rod, a spring and a brake handle. The upper end of the bend part of the joystick is provided with a handle; the lower part of the joystick is connected with the drive rod; one end of the connecting rod is connected with the lower end of the drive rod through a crew bolt, while the other end of the connecting rod is tilted right upward and is connected with the lower end of the driven rod through a crew bolt; the upper ends of the drive rod and the driven rod are respectively connected with the two ends of the fixed frame through bolts; one end of the spring is fixed on the screw bolt on the joint position between the drive rod and the fixed frame, while the other end of the spring is fixed on the screw bolt on the joint position between the driven rod and the fixed frame; the lower end of the driven rod is provided with the brake handle. The utility model has the advantages that the device adopts a dual-rocker mechanism to achieve a good braking effect and enhance the stability; the structure is relatively simple so as to facilitate installation, disassembly and cleaning.
Description
Technical field
The utility model relates to a kind of hand braking lugs, relates in particular to a kind of hand braking lugs of three-wheel vehicle.
Background technology
Common three-wheel vehicle braking mechanism generally comprises two kinds of set-up modes, and the first is controlled the braking mechanism that drives by pull bar on the brake frame by the brake that is installed on the handlebar, its clampingc car is swung finished car brakeing; Another brake gear mainly is arranged on the vehicle body pipe of three-wheel vehicle, realizes brake control by joystick.General three-wheel vehicle only is provided with the handgrip brake gear, and when cargo capacity was big, the inertia of three-wheel vehicle itself was also big, then can't reach the effect of brake in the short time, even also exist certain danger.Therefore, much existing three-wheel vehicle exists the too urgent or slow excessively defective of brake, and the too complicated not quick detachable or cleaning of structure because of brake gear does not have good practicality.
The utility model content
The purpose of this utility model provides a kind of hand braking lugs of three-wheel vehicle, with the bad not deficiency of quick detachable cleaning that reaches of the brake gear complex structure, the braking quality that overcome existing three-wheel vehicle.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of hand braking lugs of three-wheel vehicle, comprise joystick, fixed mount, driving lever, follower lever, connecting rod, spring and brake lever, the upper end of joystick sweep is provided with handle, the bottom of joystick connects driving lever, a wherein end of connecting rod is connected with the driving lever lower end by bolt, the other end of connecting rod to directly over tilt and with the lower end of follower lever by bolted connection, the upper end of driving lever and follower lever is respectively by the two ends of bolted connection at fixed mount; One end of spring is fixed on the bolt of driving lever and fixed mount junction, and the spring other end is fixed on the bolt of follower lever and fixed mount junction; The lower end of follower lever is provided with brake lever.
When three-wheel vehicle is in braking state, in-migration affects connecting rod on the driving lever cw, spring is upheld gradually, and the upper angled end of connecting rod then drives follower lever and moves to the direction of wheel part, up to the brake lever friction of follower lever lower end till wheel is stopped operating.
The beneficial effect of the hand braking lugs of three-wheel vehicle described in the utility model is: utilize the elasticity of double rocker mechanism principle and tire, make whole brake gear have suitable resiliency, reached good braking effect; Structure is comparatively simple, convenient installation, dismounting and cleaning; The tensioning function that resets of local position-limiting action and spring makes the stability of whole device strengthen.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the main TV structure scheme drawing of the hand braking lugs of the described three-wheel vehicle of the utility model embodiment;
Fig. 2 is the plan structure constructional drawing of the hand braking lugs of the described three-wheel vehicle of the utility model embodiment;
Fig. 3 is the braking state scheme drawing of the hand braking lugs of the described three-wheel vehicle of the utility model embodiment.
Among the figure:
1, handle; 2, joystick; 3, fixed mount; 4, driving lever; 5, follower lever; 6, connecting rod; 7, spring; 8, rack section; 9, bolt; 10, wheel part; 11, brake lever; 12, the spacing point of initial condition; 13, the spacing point of braking state; 14, shrinkage pool.
The specific embodiment
Shown in Fig. 1-2, the hand braking lugs of the described three-wheel vehicle of the utility model embodiment, comprise joystick 2, fixed mount 3, driving lever 4, follower lever 5, connecting rod 6, spring 7 and brake lever 11, the upper end of joystick 2 sweeps is provided with handle 1, the bottom of joystick 2 connects driving lever 4, a wherein end of connecting rod 6 is connected with driving lever 4 lower ends by bolt 9, the other end of connecting rod 6 to directly over tilt and be connected by bolt 9 with the lower end of follower lever 5, the upper end of driving lever 4 and follower lever 5 is connected the two ends of fixed mount 3 respectively by bolt 9; Be provided with the spring 7 of tensioning and reset response in the inboard of whole device, one end of spring 7 is fixed on the bolt 9 of driving lever 4 and fixed mount 3 junctions, the other end of spring 7 is fixed on the bolt 9 of follower lever 5 and fixed mount 3 junctions, and the upper surface of fixed mount 3 is provided with two and is used for whole device is positioned at shrinkage pool 14 on the rack section 8; The corner of the lower end of follower lever 5 is provided with brake lever 11.When three-wheel vehicle was in non-braking state, spring 7 kept virgin state, and driving lever 4 can be spacing at initial condition limit site 12 place by connecting rod 6 with follower lever 5.
As shown in Figure 3, the hand braking lugs of the described three-wheel vehicle of the utility model embodiment, when three-wheel vehicle is in braking state, in-migration affects connecting rod 6 on driving lever 4 cws, spring 7 is upheld gradually, the upper angled end of connecting rod 6 then drives follower lever 5 and moves to the direction of wheel part 10, up to brake lever 11 friction of follower lever 5 lower ends till wheel is stopped operating; At this moment, in order to control the action radius of driving lever 4 and follower lever 5, it is spacing at the spacing point of braking state 13 places to make the two pass through connecting rod 6.
