Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

As shown in fig. 1-9, the present embodiment provides a brake pedal spindle assembly, which includes a pedal bracket 1, a fastening bolt 2 passing through the pedal bracket 1 is engaged with a lock nut 3, the fastening bolt 2 is sleeved on the inner side of the pedal bracket 1 and is provided with a spindle assembly, the spindle assembly is connected with a pedal arm 7, and the spindle assembly is not in direct contact with the inner side of the pedal bracket 1. The pedal support 1 of the embodiment assembles the brake pedal on the front floor, and the pedal support 1 has simple structure and reliable fixation. The fastening bolt 2 and the locking nut 3 fasten the mandrel component and the pedal support 1 together, after the moment is tightened, the pedal support 1 is equivalently reinforced once, and the rigidity and the stability of the mechanism are improved. After the fastening bolt 2 and the locking nut 3 are fastened, the mandrel component is pressed in the pedal support 1, the mandrel component is not in direct contact with the inner side of the pedal support 1, and abnormal sound of the mandrel component and the pedal support 1 is avoided.

The pedal bracket 1 of the embodiment comprises a bracket body, a left bracket and a right bracket which are arranged at two ends of the bracket body; the fastening bolt 2 penetrates through the right bracket and the left bracket and is connected with the locking nut 3 in a matching way; the core shaft assembly is sleeved between the right support and the left support on the fastening bolt 2.

The mandrel component of the embodiment comprises a mandrel 4 sleeved on the fastening bolt 2, a mandrel bushing 6 sleeved on the mandrel 4 and a mandrel tube 5 sleeved on the mandrel bushing 6; the spindle tube is connected to the pedal arm 7.

Specifically, the spindle tube is provided with an inter-spindle for connecting the pedal arm 7. The spindle tube 5 is not in direct contact with the inside of the pedal bracket 1. The length of the mandrel tube 5 is less than the length of the mandrel 4. The length of the mandrel pipe 5 is 1-2 mm less than that of the mandrel 4. After the fastening bolt 2 and the locking nut 3 are fastened, the mandrel 4 is pressed in the pedal bracket 1, and the pedal bracket 1 avoids pressing the mandrel pipe 5. Through the clearance adjustment of dabber bush 6, the length of dabber pipe 5 compares in the preferred short 1mm of dabber 4, and fastening

bolt

2 and 3 fastening backs of a lock nut, dabber pipe 5 has not been compressed tightly, can realize the free rotation and not the jamming, and the clearance accessible of dabber pipe 5 and a dabber 4 simultaneously is adjusted by dabber bush 6, has both avoided the mechanism pine spaciously, has avoided the jamming of mechanism again, the problem of not return.

The two spindle bushes 6 of the present embodiment are symmetrically arranged on the spindle 4. The mandrel bush 6 is of a columnar structure and is an open-type bush, and a flanging is arranged on the mandrel bush 6; the flanging of the mandrel bush 6 is tightly attached to the inner side of the right bracket, and the outer side of the right bracket is tightly attached to the fastening bolt 2; the flanging of the other mandrel bush 6 is tightly attached to the inner side of the left support, and the outer side of the right support is tightly attached to the locking nut 3. Specifically, the mandrel bush 6 is of a columnar structure, one end of the columnar structure is provided with a flanging, the length of the mandrel bush 6 is far smaller than that of the mandrel 4, the end, without the flanging, of the mandrel bush 6 is inserted between the mandrel 4 and the mandrel tube 5, the inner side of the flanging of the mandrel bush 6 is close to the mandrel tube 5, and the mandrel tube 5 is separated from the pedal bracket 1. The mandrel bush 6 is fitted between the mandrel tube 5 and is integrally provided with a slot (not shown) to allow fine adjustment of the gap between the mandrel 4 and the mandrel tube 5 according to the dimensional tolerance of the mandrel.
