Problems solved by technology

However, there are certain defects in a single system—although the mechanical system has high reliability, it is difficult to have multiple functions such as vehicle parking brake and vehicle automatic driving brake; although the wire control system can complete the braking of all working conditions , but deficient in brake feel and reliability
At present, there is no integrated braking system with mechanical and wire control, which can realize the braking function of the vehicle under all working conditions (including the conventional driving brake of the vehicle, the parking brake of the vehicle, and the automatic driving brake of the vehicle). It can also enable the driver to obtain a good braking feeling, and at the same time, the entire braking system has high safety and reliability.

Embodiment 1

[0036] Example 1. see Figure 5 , The braking system is applied to a traditional engine-driven car, and the brake actuator adopts a mechanical structure. The brake pedal 1 and the transmission rod group 2 are welded together, installed on the vehicle frame 100 through the installation hole 4, and hidden under the bottom plate 3. The return spring 14 is installed on the vehicle frame 100 and connected to the connecting portion 17 at the rear end of the transmission rod set 2 . The first wire rope 6 is connected to the rear side of the connection part 17 of the transmission rod group 2, and is connected to the brake caliper (brake shoe 8) through the brake sheave 7, and the brake caliper (brake shoe 8) and the brake disc (brake drum) 9) Connect.

[0037] During conventional braking, the driver steps on the brake pedal 1, and the transmission rod group 2 rotates around the mounting hole 4, and the first steel wire rope 6 is tightened through the leverage ratio, and the first s...

Embodiment 2

[0040] Example 2. see Figure 6 , The braking system is applied to traditional engine-driven vehicles, and the brake actuator adopts a hydraulic structure. The brake pedal 1 and the transmission rod group 2 are welded together, installed on the vehicle frame 100 through the installation hole 4, and hidden under the bottom plate 3. The return spring 14 is installed on the vehicle frame 100 and connected to the rear side of the connecting portion 17 of the transmission rod set 2 . The transmission rod group 2 is connected to the brake master cylinder 12, the brake master cylinder 12 is connected to the brake wheel cylinder through the hydraulic pipeline 18, and the brake wheel cylinder is connected to the brake disc (or brake shoe assembly) through the brake caliper (or brake shoe assembly). Moving drum 9) is connected.

[0041] During conventional braking, the driver steps on the brake pedal 1, the transmission rod group 2 rotates around the mounting hole 4, and pulls the br...

Embodiment 3

[0044] Example 3. Such as Figure 7 As shown, the brake system is used on the electric vehicle driven by the hub motor 13, and the brake actuator adopts a mechanical or hydraulic structure (see Figure 7 ).

[0045] During conventional braking, the braking process is the same as in Embodiment 1 or Embodiment 2.

[0046] During parking braking, the braking process is the same as embodiment 1 or embodiment 2.

[0047] During automatic braking, the ECU control unit receives the signal from the sensor and controls the forward and reverse rotation of the brake motor 10. The brake motor 10 is connected to the worm gear 11, and the worm gear 11 is connected to the transmission rod group 2 through the second wire rope 5, and the transmission rod group 2. Connect the brake master cylinder 12, and connect the brake wheel cylinder through the hydraulic pipeline 18. The brake wheel cylinder drives the brake caliper (brake shoe 8) to clamp the brake disc (brake drum 9) to complete autom...

Abstract

The invention discloses a manually-operated and linearly-controlled integrated brake system, which comprises a transmission rod group, wherein the transmission rod group is arranged below a vehicle frame through an installation hole; the transmission rod group rotates around the installation hole; the front end of the transmission rod group is a pedal, and the rear end of the transmission rod group is a connection part; and the front side of the connection part is connected with a motor group which is connected with an electronic control unit (ECU), and the rear side of the connection part is connected with a brake actuator of a brake wheel. By adoption of the manually-operated and linearly-controlled integrated brake system, various kinds of working conditions such as mechanical brake, parking brake and automatic driving brake can be realized.

Description

technical field [0001] The invention relates to a mechanical-electrical integrated vehicle multi-working-condition braking system, in particular to a mechanical part adopting the principle of leverage, and a braking system integrated with manpower control and wire control. Background technique [0002] With the exhibition of two variable-wheelbase single-person electric concept vehicles, i-unit and i-real, from Toyota Corporation of Japan, this clean and environmentally friendly single-person ground vehicle has gradually entered people's field of vision. Since this kind of vehicle is only in the concept stage, and its top speed is much lower than that of a conventional car, the requirements for the braking system are not high. A purely mechanical structure or a wire-controlled structure is used alone, or even the in-wheel motor is reversed to complete the braking. These designs are all feasible. However, there are certain defects in a single system—although the mechanical s...
