Abstract
The utility model relates to a brake master cylinder which can prevent that an automobile is locked when the automobile is braked. The utility model is provided with a cylinder body with a piston and is characterized in that an energy storing mechanism composed of an elastic body, an adjustable air chamber and an adjusting screw rod is arranged below the front end of the cylinder body. When wheels are locked and pressure rises, the elastic body is inflated and deformed in the adjustable air chamber to cause the pressure to fall. When the pressure is over low, the air in compression in the adjustable air chamber pushes the elastic body to revert to cause the pressure to rise. The variation of the elastic body in the adjustable air chamber can play the function of energy storage, and thus a brake shoe is caused to do oscillating intermittent brake, obtaining the purposes that effective brake is realized and the locking of the wheels can be prevented.
Description
The utility model relates to hydraulic braking master cylinder for automobile, particularly a kind of master brake cylinder that can prevent locking when automobile brake.
Domestic and international hydraulic braking master cylinder for automobile commonly used, when the automobile high-speed emergency braking, wheel tends to occur the situation by locking, breaks away appearance danger easily.At this phenomenon, (English name: ABS) as independent agency, be connected and produce the anti-lock effect in the brake system of car, still, electronic type anti-lock device complex structure involves great expense, and speed of response is slower to design and manufacture anti-lock device both at home and abroad; Mechanical type anti-lock device volume is bigger, and trouble is installed, and it is not extensive to adapt to vehicle.
The purpose of this utility model is a kind of new automobile anti-lock braking master brake cylinder of development, and it has simultaneously can transmit the function that braking force can prevent wheel lockup again, reduces the danger of breakking away and occurring.
The purpose of this utility model is achieved through the following technical solutions:
The automobile anti-lock braking master brake cylinder, has a pump housing, the rear end is a piston in the pump housing, the connection holes that fore device has spring and connects with wheel cylinder, the pump housing links to each other with oil cylinder by the duct that the middle part is provided with, it is characterized in that below pump housing front end, being provided with accumulating mechanism, accumulating mechanism is by elastic body, adjustable gas chamber and adjusting screw(rod) constitute, accumulating mechanism is connected with the pump housing by the intercommunicating pore on top, and elastic body is a hollow sleeve, is located in the accumulating mechanism, its central bore is connected with the intercommunicating pore of accumulating mechanism and seals intercommunicating pore, the elastic body below is an adjustable gas chamber, and adjustable gas chamber and accumulating mechanism housing link by screw thread, and the adjustable gas chamber below is an adjusting screw(rod).
According to the automobile anti-lock braking master brake cylinder that the utility model proposes, overcome the defective that prior art exists, it makes brake device for car and anti-lock device integrated, volume is little, in light weight, simple and compact for structure, both can be made into adjustable universal, also can make according to vehicle can not mode (fixed type), is applicable to the automobile of hydraulic braking.Can also shorten stopping distance in the use, reduce wear on tyres, increase the service life, improve the safety and reliability of automobile, be the good product that promotes auto manufacturing's upgrading.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is that the A of Fig. 2 is to view.
The utility model will be further described according to accompanying drawing below:
As Fig. 1, shown in 2, the rear end is a piston 3 in the pump housing 2 of automobile anti-lock braking master brake cylinder, the connection holes that fore device has spring 4 and connects with wheel cylinder, arrow B indicates the direction that connects wheel cylinder among Fig. 1, the pump housing 2 links to each other with oil cylinder 1 by the duct that the middle part is provided with, below the pump housing 2 front ends, accumulating mechanism 9 is set, accumulating mechanism 9 is by elastic body 5, adjustable gas chamber 6 and adjusting screw(rod) 7 three parts constitute, accumulating mechanism is connected with the pump housing 2 by the intercommunicating pore on top, elastic body 5 is hollow sleeve (can adopt rubber or other elastomeric materials to make), be located in the housing of accumulating mechanism, its central bore is connected with the intercommunicating pore of accumulating mechanism and seals intercommunicating pore, elastic body 5 belows are adjustable gas chamber 6, adjustable gas chamber and accumulating mechanism housing link by screw thread, the adjustable gas chamber below is an adjusting screw(rod) 7, by turn adjustable gas chamber or adjusting screw(rod), and the size in space in the scalable air chamber.The rear end of the pump housing 2 has connecting panel 8, and Fig. 3 illustrates the A of connecting panel 8 to view.
When carrying out brake operating, piston 3 is pushed ahead, oil pressure to wheel cylinder, is driven the stop mechanism action, when wheel lockup pressure raises, oil promptly enters elastic body 5 by the intercommunicating pore of the pump housing and accumulating mechanism 9, elastic body expands distortion with the size of oil pressure in adjustable gas chamber, pressure is reduced, when oil pressure is crossed when low, by compression gas will promote the elastic body reduction in the adjustable gas chamber, and pressure is raise.Because the compressibility that gas has, and can under air-tight state, transmit the characteristics of pressure, when wheel lockup pressure raises, the variation of elastic body in adjustable gas chamber will produce the accumulation of energy effect, make brake shoe brake cheek make chattering type and intermittently brake, reach the purpose that effectively to brake and can prevent wheel lockup.
