Abstract
The utility model relates to a self-regulating mechanism of an automobile twin leading shoe brake, and the self-regulating mechanism is installed on a piston and a wheel cylinder body connected with the piston and comprises a gap pick, a ratchet wheel and a stretched spring, wherein the gap pick is arranged on the piston by a locating bolt, the gap pick is blocked and connected with the ratchet wheel, the other end of the gap pick is connected with the stretched spring connected on a gap support plate which is fixed on the piston; and the ratchet wheel is fixed on a regulating bushing which is installed inside the wheel cylinder body. After related parts are replaced and assembled on the original brake wheel cylinder, when a master pump supplies oil for the brake wheel cylinder, high oil pressure inside the wheel cylinder pushes the piston to move outwards, and the piston drives the gap support plate to simultaneously move outwards; and simultaneously, as being applied outward force, the stretched spring pulls the gap pick, and the gap pick takes the locating bolt as a support point to poke the ratchet wheel, so that the ratchet wheel is connected with the regulating bushing to rotate together; and a regulating screw is regulated outwards by screw thread, thus achieving the effect of compensating the gap between a brake shoe and a brake drum.
Description
Technical field
The utility model relates to a kind of automotive brake self-adjustment structure, the self-adjustment structure of two specifically neck hoof automotive brakes.
Background technique
Automotive brake needs to carry out the gap adjustment after friction plate and brake drum gap increase behind the use a period of time friction disc wear of being everlasting, adjusting rear brake can proper functioning.
But because the factor of road conditions and use habit etc., brake wear differs, do not reaching the time that requires on the specification or fare register friction plate serious wear, and the user is also still unaware, traditional two leading shoe brake does not have automatic adjusting mechanism, and independently gap automatic adjusting mechanism is not installed in its former design in addition again additional on this model break.Under this background, developed self-adjusting mechanism of two leading shoe brake, when friction plate and brake drum reach certain interval, slamming the brake self-adjustment structure can adjust whole brake shoe outward, supplies the gap, thereby make the break proper functioning, saved the loaded down with trivial details artificial adjustment of user simultaneously.
Two leading shoe brake on the market is that the requirement user manually adjusts break behind the certain mileage of automobile running voluntarily, and adjustment process is also very loaded down with trivial details.Cannot install additional under the background of clearance self-regulating mechanism independently at this model break, design direction has been pointed to wheel-braking cylinder, after changing on the former wheel cylinder and installing correlated parts additional, make it can reach the effect of clearance self-regulating, save the loaded down with trivial details artificial adjustment of user, guaranteed the break proper functioning.
The model utility content
The purpose of this utility model provides the novel self-adjustment structure of a kind of two leading shoe brake of automobile, solves the problem that needs loaded down with trivial details operation that automotive brake is manually adjusted behind the certain mileage of automobile running.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of self-adjusting mechanism of two leading shoe brake of automobile, on the wheel cylinder cylinder body that is installed in piston and is connected with piston, comprise gap plectrum, ratchet and stretched spring, described gap plectrum is installed on the piston by holding down bolt, gap plectrum and ratchet clamping, the other end of gap plectrum is connected with stretched spring on being connected the gap support plate, and described gap support plate is fixed on the piston; Described ratchet is fixed on to be adjusted on the lining, and described adjustment lining is installed in the wheel cylinder cylinder body.
Also be provided with the adjustment screw, adjust screw and be connected, and then realize ratchet is fixed with the adjustment lining; Ratchet and adjustment lining, pad riveted joint, oil intake nozzle is pressed into the wheel cylinder cylinder body, and bleeder screw screws, and all the other are by connections such as bolt and springs.
After changing on the former wheel cylinder and installing correlated parts additional, when master cylinder to the wheel cylinder fuel feeding, high oil pressure promotion piston outwards moves in the wheel cylinder, piston can drive the outwards motion simultaneously of gap support plate, simultaneously thereby stretched spring is owing to be subjected to outside power pulling gap plectrum, and the gap plectrum is stirred ratchet with holding down bolt as fulcrum, makes ratchet in succession to adjust lining to rotate together, by screw thread the adjustment screw is outwards adjusted, thereby reached the effect in gap between compensation brake shoe and the brake drum.
