Background technique
Three-wheeled motor car and agri-vehicle have vast market in China rural area, it is a kind of important tool that is widely used in agricultural production and rural area transportation, along with party and state helps the agriculture, rural areas and farmers building a New Socialist Countryside, the enforcement of a series of Huinong's policies such as town and country coordinated development, and China's low-speed cars had cheap, reliable in quality is durable, middle low speed, characteristics such as medium and small tonnage, not only make it better adapt to peasant's income level, usage level reaches the requirement to means of transportation, also better satisfied the needs of rural area various uses, thereby made it to have had huge market potential and current demand.At present, the break that domestic three-wheeled motor car and agricultural Transport Machinery are used mostly is mechanical type, cause driver labor intensity bigger, the reliability of braking is not high, cause traffic accident particularly easilier, caused unnecessary property loss and casualties for the user of service in vast rural area in outlying mountain area.
Summary of the invention
The technical problems to be solved in the utility model is at deficiency of the prior art, and a kind of biliquid compressing cylinder synchronous braking device that uses with three-wheeled motor car and agricultural Transport Machinery that is applicable to is provided.
The utility model biliquid compressing cylinder synchronous braking device is achieved by following technical proposals: biliquid compressing cylinder synchronous braking device is mainly by brake drum, brake shoe is two of extension springs fixedly, fore brake, back brake shoe, four in piston rod, base plate, piston rod is regulated fixed plate, piston rod is regulated fixing bolt, two of hydraulic jacks, two of piston rod adjustment disks, hydraulic oil pipe, two of brake shoe fixed pin shafts, two of brake shoe holddown springs, two of brake shoe fixing spring washers, compositions such as brake shoe fixed plate.
Two hydraulic jacks of the utility model biliquid compressing cylinder synchronous braking device are fixed by bolts on the base plate, fore brake links to each other with base plate with two brake shoe fixed pin shafts with the back brake shoe, brake shoe fixed pin shaft top is equipped with the brake shoe holddown spring fore brake and back brake shoe is pressed abd fixed in the base plate, play fixedly fore brake and back brake shoe, it simultaneously also is the running shaft of fore brake and back brake shoe, fore brake and back brake shoe all are in quick condition, piston rod is installed in the two ends of two hydraulic jacks respectively, have the piston rod adjustment disk on two piston rods of one end hydraulic jack, two piston rods of the other end hydraulic jack are not with the piston rod adjustment disk, the piston rod that has the piston rod adjustment disk is after adjusting the gap of fore brake and back brake shoe and brake drum, piston rod is regulated two ends that fixing bolt regulates fixed plate with piston rod and is pressed in the groove on the piston rod adjustment disk, the gap of brake shoe and brake drum is remained unchanged, the steel plate at fore brake and brake shoe two ends, back inserts in the groove of piston rod end face, all strain with spring at fore brake and brake shoe two ends, back, make the groove fluid-tight engagement of fore brake and back brake shoe and piston rod end face, brake shoe fixed plate two ends groove engages with groove on the brake shoe steel plate, brake body is fixed in the base plate, it is parallel that brake shoe and base plate are remained, and hydraulic oil pipe links to each other with the hydraulic braking wheel cylinder.
Braking force of the present utility model is from the operator of three-wheeled motor car and agri-vehicle machinery, when operator act on brake petal with braking force, the breaking force of hydraulic braking acts on the hydraulic pressure wheel cylinder, the hydraulic pressure wheel cylinder makes pressure oil enter the brake fluid pressure oil cylinder from hydraulic oil pipe, the two-piston bar that two hydraulic jacks promote respectively separately is protruding, and four piston rods promote fore brake from two ends and the back brake shoe opens brake shoe; Fore brake and back brake shoe engage generation frictional force and cause braking action with brake drum, two hydraulic jacks are applied to breaking force in whole braking process on fore brake and the back brake shoe simultaneously, and make it outwards open to engage and produce friction catch moment with brake drum, reach the purpose of braking.There is not restricting relation mutually between two hydraulic brakings in this braking system, breaking force in the braking process acts on two hydraulic jacks simultaneously, brake shoe is engaged fully with brake drum surface, when acting on simultaneously, two hydraulic jacks can produce bigger braking moment in the braking process, so this braking device has more reliable braking effect.
