Abstract
The utility model relates to a floating adjustable brake device. A brake disc is movably provided with two arc-shaped horseshoes, and the outside of each arc-shaped horseshoe is provided with a brake sheet. A camshaft which can cause the two horseshoes to be outwards spread open is arranged in a shaft sleeve which is fixed on the brake disc, and a pullback spring is connected between the horseshoes. The utility model is characterized in that the lower part of the brake disc is provided with a horseshoe adjusting device, and the lower ends of the horseshoes are movably inserted in both ends of the horseshoe adjusting device. Because of the floating installation of the horseshoes, the brake sheets can sufficiently contact a brake drum, and frictional force can reach ideal value through the horseshoe adjusting device.
Description
The utility model relates to and has the break technical field that outwards mobile brake component combines with the drum internal surface, more particularly relates to have the break of two brake shoes.
At present, the brake device of motor tricycle, mostly be two shoes drum brakes, the lower end of its two shoes is hinged on the brake disc, the characteristics of this break are: the brake block of shoes outer rim can not contact cmpletely with the brake drum internal surface, thereby retardation efficiency is poor, and Security is low, and easy to wear, working life is short.
The purpose of this utility model provides a kind of braking efficiency height, and is safe in utilization, the motor vehicle brake that the life-span is long.
The technical solution of the utility model is: it comprises brake disc, is movably installed with two blocks of arc shoes on brake disc, and the outer rim of shoes is installed with the brake block that rubs mutually with the brake drum internal surface.Top at brake disc is equipped with axle sleeve, the front portion is installed in the axle sleeve stretches in camshaft between the two shoes upper ends, and the top of two shoes is connected with extension spring.Its structural feature is, in the bottom of brake disc the shoes regulating device is installed, and two shoes lower ends are actively plugged in shoes regulating device two ends, also are connected with extension spring between two shoes bottoms and brake disc.
The utility model has the advantages that: be installed on the regulating device because shoes is floating type, the big I of drag friction power is adjusted by the shoes regulating device, thereby retardation efficiency height, braking effect is good, safe in utilization, brake block is wear-resistant, long service life, can reduce maintenance, be particularly suitable for motor tricycle and use.
Below in conjunction with drawings and Examples, describe structure of the present utility model and working principle in detail.
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the A-A sectional view among Fig. 1;
Fig. 3 is the M-M sectional view among Fig. 1;
Fig. 4 is the rear view of Fig. 1;
Fig. 5 is the working position figure of camshaft;
Fig. 6 is the shoes regulating device structural representation of another form;
Fig. 7 is the left view of Fig. 6.
In the embodiment that Fig. 1 provides, brake disc (3) is formed by steel plate punching press seam, go up at brake disc (3) and to be movably installed with two blocks of arc shoes (10) by the shoes hold-down devices, the shoes hold-down devices is installed in steady nail (7) formation on the brake disc (3) by being installed in the stage clip in the circular hole (9) above the shoes, steady pad (8) and passing its lower end, hole on the shoes (10).Outer rim at shoes (10) is installed with the brake block (2) that rubs mutually with brake drum (12) by rivet (1).Be welded with axle sleeve (4) on the top of brake disc (3), camshaft (5) is installed in the axle sleeve (4), the end that camshaft (5) has cam is clipped between two shoes (10) upper end, and the end in addition of camshaft (5) is connected with clamping handle (13).In the bottom of brake disc (3) a shoes regulating device (19) is installed, this device comprises that one is utilized screw (14) and spring washer (15) to be installed in adjustment bearing (18) on the brake disc (3), in the hole of adjusting bearing (18) two ends, respectively be equipped with one and adjust nut (16), adjust in the nut (16) and adjustment screw (17) is installed by screw thread, shoes (10) lower end activity is placed in the breach of adjusting screw (17) end, be equipped with the inwardly extension spring (6) of tension of two shoes on the top of two shoes (10), between shoes (10) bottom and brake disc (3), also be connected with the inwardly extension spring (11) of tension of shoes.During use, brake disc of the present utility model (3) is fixed on the land (20) on the transmission shaft (21), during normal vehicle operation, brake block (2) leaves brake drum (12) in company with shoes (10) under the effect of extension spring (6), during brake, clamping handle (13) drives camshaft (5) and turns an angle under tension, and the cam portion on the camshaft outwards struts two shoes (10) together with brake block (2), produce friction with brake drum (12), realize braking.Because shoes (10) lower end can move up and down in adjusting screw (17), thereby brake block can fully contact with brake drum, and the big I of frictional force is by rotation adjustment nut (16) realization.
Another embodiment of the present utility model is that shoes regulating device (19) is adjusted nut (22) by one, is installed in the fixed support (24) of adjusting nut one end, and is installed in adjustment support (23) formation of adjusting nut (22) the other end by screw thread.Two shoes (10) lower end is actively plugged in fixed support (24) respectively and adjusts in the breach that supports (23) end.Regulate the size of drag friction power by rotating nut (22).
