Abstract
The utility model relates to a brake for driving and parking for motor tricycle, belonging to motorcycle manufacture technology field, which is characterized in that a cylinder 6 with double pistons is arranged at a motherboard of the brake between ends of a brake shoe 3 and brake shoe 12 which are arranged in opposite direction. A piston top block 5 and a piston top block 7 connected with a piston top block 4 and a piston top block 8 are connected with the ends of the brake shoe 3 and the brake shoe 12 to form a transmission device. The double piston brake cylinder 6 is connected with a primary brake cylinder by an oil pressure. The brake with high performance integrates driving brake and parking brake. The utility model has the advantages of simple structure and strong braking capacity, less stepping force and smooth operation. The braking and transmission operation is simple and reliably, the sliding on slope can be effectively avoided, and the brake is widely applied in tricycle motors.
Description
Technical field
The utility model relates to the driving of motor tricycle, the dual-purpose drg that stops, and belongs to motor bike manufacturing technology field.
Background technology
At present, the driving of known motor tricycle, parking brake adopt traditional two-wheeled motor vehicle drum brake mechanism.Its mechanism is that pull bar traction rocking arm drives brake shoe expander with brake shoe and brake wheel tensioner.During parking brake pedal is locked or be provided with special-purpose hand braking handle with Drag link tightener, reach the purpose of stopping brake.There is serious accident potential in this simple structure, in case drg pull bar, rocking arm break down, driving, parking brake are then simultaneously malfunctioning, and consequence is hardly imaginable.In addition, the braking force overbalance of this traditional braking device, two trailing wheels are easy to generate sideslip, and required braking legpower is bigger.Particularly because brake plate often is in positive break-in state, when the upward slope stopping brake, the applying of plugging sheet is bad, and the slide car can take place, and influence is controlled vehicle, even serious traffic accident takes place.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of reliability height, the motor tricycle driving parking two-purpose brake of driving, parking brake one.
The technical scheme that its technical matters that solves the utility model adopts is: the fixed rotating shaft (fulcrum) of traditional motor tricycle drum brake mechanism brake shoe is removed, employing is installed in the piston jacking block of the double-piston brake cylinder (being commonly called as wheel cylinder) on the brake support plate respectively with two brake shoe opposing ends support fixation, constitutes the walking drg; Be the brake shoe expander of semicircle axle in the middle of the brake shoe expander that links with brake shoe in traditional drum brake mechanism made into, the semicircle axle in the middle of the brake shoe expander and the semi-circular groove of two brake shoe terminal parts constitute the location fulcrum of brake shoe, and brake shoe expander promotes brake shoe and constitutes parking brake.So constitute the motor tricycle driving parking two-purpose brake of driving, parking two cover maneuvering systems.
Below introduce structure of the present utility model in detail: a kind of motor tricycle driving parking two-purpose brake, by brake wheel, brake support plate, and the brake shoe that is installed in the band brake sheet on the brake support plate, retarding spring, brake shoe expander, brake rocker arm, the brake rocker arm spring is formed, it is characterized in that between the end of two relative brake shoes a double-piston brake cylinder that is fixed on the brake support plate being arranged, the piston of double-piston brake cylinder connects the piston jacking block and connects the formation transmission device with the terminal part kissing of two brake shoes respectively, and the double-piston brake cylinder has high pressure fuel pipe to be connected with the main brake oil cylinder.
During the utility model work, depress brake pedal, braking liquid in the main brake oil cylinder passes to the double-piston brake cylinder through high pressure fuel pipe with pressure, the piston of double-piston brake cylinder promotes the end that the piston jacking block acts on two brake shoes respectively, makes brake shoe and brake wheel be adjacent to the enforcement braking and finishes the service brake operation; The hand braking handle of pull-up after stopping, pull bar tractive brake rocker arm rotates, and brake shoe expander is adjacent to the enforcement braking with brake shoe and brake wheel, finishes the stopping brake operation.
The utility model adopts two cover operating systems to control brake shoe respectively, and performance simple in structure is reliable, and braking force is strong.The brisk agility of service brake, required braking legpower is less, controls freely.The stopping brake mechanical drive is easy to be firm, and is durable in use, can effectively solve the deficiency of ramp parking slide car.Can be widely used in the brake equipment of various motor tricycles.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Figure of description is a structural representation of the present utility model.Among the figure: 1 brake support plate, 2 brake plates, 3 brake shoes, 4 piston jacking blocks, 5 pistons, 6 brake cylinders, 7 pistons, 8 piston jacking blocks, 9 retarding springs, 10 brake plates, 11 retarding springs, 12 brake shoes, 13 brake shoe expanders, 14 semicircle axles, 15 brake wheels.
The specific embodiment
In the accompanying drawing illustrated embodiment: by brake wheel 15, brake support plate 1, and be installed in band brake sheet 2 on the brake support plate 1,10 brake shoe 3,12, retarding spring 9,11, brake shoe expander 13, brake rocker arm, the brake rocker arm spring is formed, it is characterized in that two relative brake shoes 3, a double-piston brake cylinder 6 that is fixed on the brake support plate 1 is arranged between 12 the end, the piston 5 of double-piston brake cylinder 6,7 connect piston jacking block 4,8 respectively with two brake shoes 3,12 end kissing connects the formation transmission device, double-piston brake cylinder 6 has high pressure fuel pipe to be connected with the main brake oil cylinder, with brake shoe 3, be semicircle axle 14 shapes, semicircle axle 14 and two brake shoes 3 in the middle of the brake shoe expander 13 in the middle of 12 brake shoe expanders that are abutted against mutually 13, the semi-circular groove of 12 the other end constitutes the location fulcrum of brake shoe.
The structure of double-piston brake cylinder 6 is close with traditional hydraulic braking wheel cylinder, and high pressure fuel pipe interface and the venting valve that communicates with oil cylinder arranged on the cylinder body of relative twin piston centre in the double-piston brake cylinder 6.
The spacing annular boss that connects with brake cylinder 6 two ends kissings is arranged on the piston jacking block 4,8, be used for the reference position of brake shoe is limited.
