Problems solved by technology
Since the braking force of the front axle is weakened while the braking force of the rear axle is reduced, the braking force of the whole vehicle will be greatly reduced, which will bring great potential safety hazards to the driver and passengers.

Embodiment Construction
[0035] In order to make the above objects, features and advantages of the invention more obvious and comprehensible, specific implementations of the invention will be described in detail below.
[0036] In the following description, a lot of specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described here, and those skilled in the art can do it without departing from the meaning of the present invention. By analogy, the present invention is therefore not limited to the specific examples disclosed below.
[0037] Such as Figure 4 to Figure 7 As shown, the present invention first proposes a valve body 1 of a load-sensing proportional valve, which includes a valve body body 11, and the valve body body 11 includes a rear axle brake fluid inlet 111, an oil pressure adjustment chamber 112 and A brake fluid outlet 113, the valve body 11 also includes a bypass hole 1...

The invention provides a load sensing proportional valve body and a load sensing proportional valve. The load sensing proportional valve body comprises a valve body, wherein the valve body comprises a back axle brake liquid inlet, an oil pressure adjusting cavity and a brake liquid outlet which are sequentially communicated. The load sensing proportional valve body is characterized in that the valve body also comprises a bypass hole which is used for communicating the back axle brake liquid inlet and the brake liquid outlet; when the brake force of a front axle is not reduced, the bypass hole is sealed, and the back axle brake liquid inlet and the brake liquid outlet are not communicated; when the brake force of the front axle is reduced, the bypass hole is opened, and the back axle brake liquid inlet and the brake liquid outlet are communicated. The load sensing proportional valve body has the advantage that when the brake force of the front axle is reduced, the bypass hole is opened, the back axle brake liquid directly flows from the back axle brake liquid inlet to the brake liquid outlet, and does not flow into the oil pressure adjusting cavity, and the oil pressure of the back axle brake liquid is not reduced, so the brake force of a whole automobile is guaranteed, and the driving safety of the automobile is improved.
Description
technical field [0001] The invention relates to an automobile brake system, in particular to a load-sensing proportional valve body and a load-sensing proportional valve using the load-sensing proportional valve body. Background technique [0002] When the car is unloaded or fully loaded, the deformation of the suspension is inconsistent, resulting in a change in the relative height difference between the frame and the rear axle. The load-sensing proportional valve uses this phenomenon to adjust the opening of the valve body through the change of the height difference, thereby adjusting the brake oil pressure. The adjusted oil pressure is then input into the rear axle brake to control the output of the brake force to meet the requirements of the vehicle. The demand for braking ensures the stability of the vehicle during braking and improves the safety of the vehicle. [0003] Such as figure 1 As shown, the existing load-sensing proportional valve includes a valve body 1', ...
