Abstract
A brake air chamber for solving off tracking of braking comprises a front shell body, a back shell body, a push plate assembly, a lathedog, a diaphragm, a return tower spring, a front fork, a front fork locknut, a thread bushing and a spring seat. The push plate assembly comprises a push plate and a push rod welded on the push plate. The diaphragm, the push plate assembly, the return tower spring, the spring seat and the front shell body with thread bushing screwed in are placed in the back shell body in sequence, and are clamped tightly through the lathedog. The brake air chamber for solving off tracking of braking is characterized in that a welding nut screwed with the thread bushing is welded on the outer end face of the front shell body, the spring seat is arranged between the thread bushing and the return tower spring, lubricating grease is coated on the contact area of the spring seat and the thread bushing, and the thread bushing can rotate flexibly in the spring seat. The brake air chamber for solving off tracking of braking has the advantages of being labor-saving in adjusting, wide in adjusting range and long in push rod stroke. A compression amount of the return tower spring can be adjusted through the length of the thread bushing screwed in, the output force and the response time of the brake air chamber are adjusted, and the difference between the driving force and the braking time are eliminated when a vehicle brakes, and the problem of off tracking of braking can be effectively solved.
Description
Technical field
The utility model relates to a kind of technical field of air pressure braking system of automobile, specifically a kind of diaphragm brake chamber of the time brake sideslip that solves automobile brake.
Background technique
At present, common diaphragm brake chamber is by forward and backward housing, and several parts such as diaphragm, push-plate, push rod, return spring, clip, front fork form, and by passing into and discharge pressurized air, realize running braking function.Running braking function is the service brake air chamber to be passed into pressurized air act on generation power on the diaphragm, and actuate push rods acts on to be adjusted on the arm, adjusts again rotating cam axle of arm, and then for wheel drag provides driving force, thereby realize service brake.
The characteristics such as existing common diaphragm brake chamber is simple in structure with it, volume is small and exquisite, adaptive capacity to environment is strong are adopted by most auto vendors.But there is the shortcoming that ouput force and response time can not regulate in common air chamber, and this is unfavorable to brake sideslip of eliminating vehicle, and the brake sideslip directly endangers traffic safety.
The phenomenon that vehicle during so-called brake sideslip refers to travel changes direction of travel because of brake is expressed as left sideslip and to the right sideslip usually.
The braking force that left and right sides break produced when the basic reason of sideslip of causing braking was brake does not wait or left and right sides break exists and brakes the time difference.Therefore, as long as invention a kind of energy adjustable brake air chamber ouput force and the Novel brake chamber of response time just can solve the brake deviation phenomenon.
The model utility content
A kind of brake chamber that solves the brake sideslip, it is comprised of front case, rear case, push-plate assembly, clip, diaphragm, return tower spring, front fork, Front fork lock jack panel, thread bush, spring seat.The push-plate assembly comprises: push-plate and the push rod that is welded on the push-plate.On rear case, put into successively the front case of diaphragm, push-plate assembly, return tower spring, spring seat, screw-in thread bush, tighten with clip, it is characterized by: described front case is welded with the welded nut that screws thread bush on the exterior edge face, between described thread bush and return tower spring spring seat is installed, lubricating grease is smeared in spring seat and thread bush contacting point, thread bush can be in spring seat flexible rotating.
The utility model has carried out architecture advances to existing common diaphragm brake chamber assembly, thread bush, spring seat and welded nut have been set up on the original basis, design a kind of novel diaphragm brake actuator of regulating return tower spring decrement, regulated ouput force and the response time that can change the air chamber push rod by the return tower spring decrement to this air chamber.
The utlity model has and regulate advantage laborsaving, that regulation range large, the push rod stroke is large, regulate the decrement of return tower spring by the screw-in length of thread bush, regulate ouput force and the response time of air chamber, poor and the braking time difference of the driving force of two side brakes when eliminating service brake, can effectively solve brake sideslip problem.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is the described a kind of structural drawing that solves the brake chamber of brake sideslip of the utility model embodiment.
Embodiment
As shown in Figure 1, in present embodiment, described a kind of brake chamber that solves the brake sideslip comprises return tower spring 1; Place the push-plate assembly 2 of described return tower spring; The diaphragm 3 that contacts with described push-plate assembly; Rear case 4; Front case 6; Tighten the clip 5 of described rear case, diaphragm, front case; Screw the front fork 7 on push rod; Lock the nut 8 of described front fork; Be welded on the welded nut 9 of described front case exterior edge face; Screw on described welded nut and the thread bush 11 of holddown spring seat 10.
This brake chamber realizes that principle and the method for brake-force control is as follows:
Because the thread bush 11 of this brake chamber of rotation can make the decrement of return tower spring 1 change, spring force changes thereupon, therefore after brake chamber passed into pressurized air, the spring return function power size that runs into was adjustable, so the ouput force of braking air chamber push rod and response time, change also occured.The utility model utilizes the change of push rod ouput force and response time to make poor and braking time difference of the driving force of braking system left and right sides break be compensated and eliminate just, thereby has effectively solved brake sideslip problem.
With vehicle left during sideslip this brake chamber assembly be adjusted to example.Vehicle sideslip explanation left left side braking force is large or braking response is fast, can increase return tower spring 1 decrement by regulating thread bush 11, reduces left side braking force and delays the braking response time, solves sideslip problem left.
Regulating method: the circular hole that Phillips screwdriver is inserted thread bush 11 front ends, the rotation screw cutter drives thread bush 11 rotations, make thread bush 11 indentation in the air chamber, this moment, return tower spring 1 decrement increased to the indentation in the air chamber with thread bush 11, and the indentation amount of thread bush 11 can be decided as required.
The utlity model has and regulate advantage laborsaving, that regulation range large, the push rod stroke is large, regulate the decrement of return tower spring 1 by the screw-in length of thread bush 11, regulate ouput force and the response time of air chamber, poor and the braking time difference of the driving force of two side brakes when eliminating service brake, can effectively solve brake sideslip problem.
