Abstract
The invention relates to a mounting structure of a push rod assembly of a parking brake rod assembly. The mounting structure comprises a parking brake control rod, a push rod assembly and a ratchet pawl, wherein one end of the push rod assembly is connected with the ratchet pawl, and the connected part is positioned in the parking brake control rod. The mounting structure is characterized in that the end of the push rod assembly connected with the ratchet pawl is of a bending structure, a hole is arranged on the ratchet pawl, and the bending part at the end part of the push rod assembly is inserted into the hole and is in clearance fit with the hole. In the mounting structure, the end part of the push rod assembly is bent and is connected to the hole of the ratchet pawl, the problem that the idle stroke during running is large if the end part of the push rod assembly is connected to a slot formed on the ratchet pawl is solved, the idle stroke during running of the push rod assembly adopting the structure is smaller, the button stroke is also smaller, so that the comfort in operating the parking brake rod assembly can be improved. At the same time, the push rod can be prevented from escaping the ratchet pawl, and the interference between the push rod and the parking brake control rod during motion can be avoided.
Description
Technical field
The present invention relates to automobile parking braking mechanism, be specifically related to the push rod assembly of braking during standstill bar assembly and the mounting structure of ratchet pawl.
Background technology
Referring to Fig. 1, automobile parking braking bar assembly normally comprises tooth plate and bearing by parking brake lever 8, ratchet board component 7(), ratchet pawl 5, braking during standstill light switch assembly 6, push rod assembly 4, handle 2, button 1, spring 3 etc. form.Wherein push rod assembly 4 normally cooperates with fluting on the ratchet pawl 5, and control ratchet pawl 5 rotates around rivet.Because this structure need be to ratchet pawl 5 flutings, push rod assembly 4 slide relative in fluting is bigger, causes the motion idle travel bigger, links together with push rod assembly 4, and the button stroke that is used for operator's operation is bigger, and operation comfort is relatively poor.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of push rod assembly of braking during standstill bar assembly and the mounting structure of ratchet pawl, reduces the motion idle travel of push rod assembly, thereby reduces the button stroke, improves operation comfort.
Take following technical scheme for solving the problems of the technologies described above the present invention:
A kind of mounting structure of push rod assembly of braking during standstill bar assembly, it comprises parking brake lever, push rod assembly and ratchet pawl; One end of described push rod assembly is connected with ratchet pawl, and this connecting portion is in parking brake lever; It is characterized in that described push rod assembly is connected an end with ratchet pawl be bending structure, has perforate on ratchet pawl, the bending part of push rod assembly end inserts in the described perforate, with the perforate free-running fit, and the rotation of control ratchet pawl.
This structure is carried out ways of connecting with the bending of push rod assembly end with the ratchet pawl perforate by adopting, overcome the big problem of operation idle travel that causes with ratchet pawl fluting type of attachment, the motion idle travel of this structure push rod assembly is less, make the button stroke also less, thereby can improve the traveling comfort of braking during standstill bar assembly operation.Can guarantee that simultaneously push rod do not deviate from from ratchet pawl, and avoid push rod and parking brake lever in motion process, to interfere.
Description of drawings
Fig. 1 is the scheme drawing of general-duty braking during standstill bar assembly;
Fig. 2 is the scheme of installation of push rod assembly.
The specific embodiment
General-duty braking during standstill bar assembly is formed as shown in Figure 1: button 1 is injection-moulded in push rod assembly 4, and an other end of push rod assembly 4 is with ratchet pawl 5 assemblings.Ratchet pawl 5 is by rivet and parking brake lever 8 riveted joints, and ratchet pawl 5 rotates around the riveted joint rotating shaft under the control of button 1 and push rod assembly 4.After spring 3 is installed in button 1, and opens limiting stopper be used to limit its initial compression length on the parking brake lever assembly, it act as and makes button 1 return.Ratchet pawl 5, ratchet board component 6 are riveted together by rivet and parking brake lever 8, and parking brake lever 8 rotates around the axis.Braking during standstill light switch assembly 6 by rivet on ratchet board component 6.Ratchet board component 6 is made up of tooth plate and bearing, in use makes braking during standstill bar assembly have latch functions by ratchet pawl 5 and tooth plate engagement.
Wherein the mounting means of push rod assembly is seen Fig. 2: on ratchet pawl 5 perforate is arranged, the end bending of push rod assembly 4, before assembling parking brake lever 8, the bending part of push rod assembly 4 is placed in the middle of the perforate of ratchet pawl 5, with the perforate free-running fit, and then at they outside assembling parking brake levers 8.During design, need to calculate the length of the bending part of push rod assembly 4, make it can guarantee that push rod assembly can not deviate from from the perforate of ratchet pawl 5, also avoid push rod assembly 4 and parking brake lever 5 in motion process, to interfere.The motion idle travel of this structure push rod assembly is less, and the button stroke is less, and operation comfort is better.
