Description

A kind of brake pedal belt supporting frame assembly

Technical field

The utility model is related to a kind of automobile component, more particularly to a kind of brake pedal belt supporting frame assembly.

Background technology

Brake pedal belt supporting frame assembly is important component in brake system of car, and its main function is：1 and power-assisted Device assembly abutting joint is on vehicle body；2nd, brake pedal is stepped on by pin transmit pedal force in the rear of brake pedal to booster Brakes is worked on assembly, be also turned on brake switch and open braking automobile warning light；3rd, loosening the brake Bumper step, which returns to initial position, makes brakes terminate braking operation, simultaneously switches off brake switch and closes braking automobile warning light Close；Thus it is guaranteed that the pedal of brake pedal belt supporting frame assembly is after pedal force is unclamped, can return to initial position most important.

The pedal return of brake pedal belt supporting frame assembly relies primarily on return spring（As shown in Figure 1）, in prior art, The return spring used（Referring to the return spring I in accompanying drawing 4-5）Number of total coils is 11.5 circles, and number of active coils is 10 circles, return bullet Spring external diameter is φ 26.5, and a diameter of φ 2.5 of carbon spring steel wires of return spring I is made；The problem of existing be：

1., can only be by the hook of two installation ends because the external diameter of return spring I is larger（Link up with upper end and hook lower end）If Count into the big one end in one end small, cause manufacturing process complicated；

2. small end hangs over the top of mounting bracket when installing, big end hook is hung on pedal arm, easy if hanging instead There is return spring to encounter upper bracket and produce noise, and the risk for thering is return spring to come off；

It is painstaking on pin when touching on the brake, stop 3. because the rigidity k value of the return spring I is larger, i.e., returning place force is excessive Car is hard and braking effect is poor, excessive to brake switch impulsive force in releasing of brake, easily causes brake switch displacement and easy Damage brake switch.

Utility model content

The purpose of this utility model is in the case where installation dimension and maximum functional stroke are constant, to existing return spring It is improved and carries simple in construction, the suitable return spring of rigidity k value brake pedal belt supporting frame assembly there is provided a kind of, To make up the deficiency of prior art.

Solving the technical scheme of above-mentioned technical problem is：A kind of brake pedal belt supporting frame assembly, including pedal, pedal Arm, upper bracket and return spring, the return spring are arranged in the mounting bracket being connected with upper bracket, on its " U " type hook End hook hangs over mounting bracket top, and " U " type hook lower end is hooked on pedal arm；The return spring external diameter is φ 23.6, always The number of turns is 14 circles, and number of active coils is 13 circles, and a diameter of φ 2.2 of carbon spring steel wires of return spring, the bullet of return spring is made Spring rigidity k is:2.0~2.3N/mm.

Its further technical scheme is：The installation end size of return spring two is identical, i.e. its " U " type hook upper end with " U " type hook lower end size is identical.

Due to using above-mentioned technical proposal, compared with prior art, a kind of brake pedal belt supporting frame of the utility model is total Into having the advantages that：

1. because the external diameter of return spring reduces, therefore being not in the situation that return spring encounters upper bracket, it can avoid The risk that the generation of noise and return spring come off；

2. because the rigidity k value of return spring is suitable, the problems such as brake is hard, brake is painstaking is solved, can effectively be changed Kind braking effect, while can avoid damaging brake switch, extends the service life of brake pedal；

3. because the external diameter of return spring reduces, return spring two ends " U " type hook can be identical for size, not only makes return The manufacturing process of spring becomes simple, is easy to manufacture, and be easily installed.

Below, a kind of technical characteristic of brake pedal belt supporting frame assembly of the utility model is made in conjunction with the accompanying drawings and embodiments Further instruction.
