Detailed Description
For the sake of understanding, the present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1, the embodiment of the present invention provides an electronic hydraulic brake system including two master cylinders, which are a first master cylinder 31 and a second master cylinder 32, wherein the electric control units of the two master cylinders are all connected to a brake pedal sensor through a signal line 1, the brake pedal sensor is a sensor for detecting a brake pedal 2, and the brake pedal sensor obtains the braking intention of a driver by detecting the movement of the brake pedal 2.
As shown in fig. 1, the first master cylinder 31 is connected with the first front wheel cylinder 51 and the second front wheel cylinder 52 through brake lines to form a front axle brake circuit, the second master cylinder 32 is connected with the first rear wheel cylinder 61 and the second rear wheel cylinder 62 through brake lines to form a rear axle brake circuit, and the front axle brake circuit and the rear axle brake circuit are independent from each other, that is, the two hydraulic circuits are not communicated with each other.
When the brake master cylinder works, the first brake master cylinder 31 and the second brake master cylinder 32 receive brake signals transmitted by the brake pedal sensor from the signal line 1 and execute the same pressure building action, the cooperative control effect of the two is equal to that of a large-specification brake master cylinder, in addition, a front axle brake circuit and a rear axle brake circuit are mutually independent, and the small-specification brake master cylinders can meet the requirements of the small-specification brake master cylinders.
In other embodiments, the number of the master cylinders can be more than two, similarly, the master cylinders are connected with the brake cylinders controlled by the master cylinders through brake pipelines to form hydraulic circuits, and the hydraulic circuit in which any one master cylinder is located is independent of the hydraulic circuit in which the other master cylinder is located, so that the braking requirement of a large-tonnage vehicle can be met under the condition that the specification of the master cylinders is not increased.
In a specific practical application, each master cylinder is usually provided with an ABS module in a hydraulic circuit, for example, in the embodiment shown in fig. 1, a brake line from first master cylinder 31 to first front-wheel brake cylinder 51 and second front-wheel brake cylinder 52, or a brake line from second master cylinder 32 to first rear-wheel brake cylinder 61 and second rear-wheel brake cylinder 62 passes through ABS module 4.
In order to control the vehicle more smoothly, a balance valve is generally provided on the brake line between the first front wheel brake cylinder 51 and the second front wheel brake cylinder 52. Similarly, a balance valve may be provided on the brake line between the first rear wheel brake cylinder 61 and the second rear wheel brake cylinder 62.
