Description

Technical Field

[0001] The utility model belongs to the field of automobile accessories, and in particular relates to a pedal force arm quick installation structure. Background Art

[0002] The brake pedal is a component that the driver uses to brake the vehicle by stepping on it when the brake is needed. The pedal is usually connected to a lever arm in an integrated manner. The end of the lever arm away from the pedal is fixed on a rotating shaft, and the rotating shaft is rotatably connected to the support. When the foot steps on the pedal, the rotating shaft rotates, and one end of the lever arm also rotates with the rotating shaft, so that the connecting rod connected to the pedal pushes the hydraulic cylinder piston to push the hydraulic oil, thereby performing the braking work.

[0003] In the existing structural design, the rotating shaft is first installed on the support, and then the end of the force arm away from the pedal is fixed to the connecting ear on the rotating shaft. However, since the support includes a top plate and two side plates, the rotating shaft is surrounded, and the connecting ear on the rotating shaft is also surrounded, the installation worker's line of sight is blocked, and the mounting hole at the end of the force arm and the hole on the connecting ear are difficult to align. In addition, due to the blocked line of sight, it is not convenient for the bolts to pass through the two holes, which affects the installation speed. Utility Model Content

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the problem that in the existing automobile lever arm mounting structure, the connecting ear on the rotating shaft is surrounded by the support so that the installation worker cannot see the connecting ear, and the hole on the connecting ear is difficult to align with the mounting hole at the end of the lever arm, resulting in a slow installation speed.

[0005] In order to solve the above technical problems, the utility model provides a pedal force arm quick installation structure, including a support, two bearings, a force arm, a bolt I, a nut I and two limit sleeves, the support includes two side plates and a bottom plate, the bottoms of the two side plates can be detachably fixed on the bottom plate; each of the side plates is provided with a mounting hole, the mounting hole is in the shape of a stepped hole, including a small diameter section and a large diameter section extending along the thickness direction of the side plate, the mounting holes of the two side plates are symmetrically arranged, the small diameter sections are all on the outside, each of the large diameter sections is tightly fitted with a bearing, the two end faces of the bearing are respectively aligned with the two ends of the large diameter section, the limit sleeve is located in the small diameter section, the bolt I can be inserted into one of the limit sleeves, one of the bearings, another bearing and another limit sleeve in sequence, the tail of the bolt I is threadedly connected to the nut I, the head of the bolt I is close to the outer side surface of one of the limit sleeves, the nut I is close to the outer side surface of the other limit sleeve, and the force arm sleeve is fixed on the bolt I.

[0006] Preferably, a connecting sleeve is provided at the end of the force arm away from the pedal, a key groove I is provided on the wall surface of the connecting sleeve, a key groove II is provided on the circumferential surface of the bolt I, a flat key can be placed in the key groove II, the connecting sleeve can be sleeved outside the bolt I, and the key groove I can be tightly fitted with the protruding part of the flat key.

[0007] Preferably, fixing holes I are respectively provided on both sides of the bottom plate, flanges are provided at the bottom of the side plates, fixing holes II are provided on the flanges, and the fixing holes I and II are connected and fixed by bolts II and nuts II.

[0008] Preferably, it also includes a reinforcing bolt, and each of the two side plates is provided with a through hole, and the reinforcing bolt is inserted into the two through holes in sequence, and the tail end of the reinforcing bolt is threadedly connected to the nut III.

[0009] The technical solution of the utility model has the following beneficial effects:

[0010] The structural design of the utility model allows the force arm to be fixed on the bolt Ⅰ (equivalent to the rotating shaft) first, and then the bolt is rotated and connected to the support. It avoids the situation where the force arm is inconveniently installed and fixed to the bolt Ⅰ due to the obstruction of the support after the bolt Ⅰ is first installed on the support; since the force arm has been installed on the bolt Ⅰ, in order to avoid the force arm interfering with the installation of the bolt Ⅰ on the support, the two side plates of the support are detachably installed on the bottom plate, so that the two ends of the bolt Ⅰ can be inserted into the two side plates in turn. In order to improve the efficiency of fixing the bolt Ⅰ and the inner ring of the bearing of the side plate, the utility model adopts a clamping method for fixing, rather than the traditional interference fit, which is faster to install.
