Abstract
The utility model discloses an automatically controlled loading sensing proportioning valve, including proportion valve body and the driving motor of mount setting on the mount, and be used for detecting the pressure measurement of pressure between frame and the rear axle, and be used for controlling driving motor pivoted programmable controller, the hinge joint of proportion valve body has the rack that stretches out outside the valve body, and overlap outside the rack and put the dust cover, driving motor's axle head extends to in the dust cover to the tip be equipped with with the adhesive gear of rack, programmable controller is connected with pressure measurement and driving motor electricity, this proportional valve has adopted pressure measurement as sensing element, adopts the motor to adjust piston motion simultaneously to reach the accurate control proportional valve effectively, obtain more reasonable brake force distribution effect.
Description
Technical field
This utility model relates to a kind of auto parts machinery, especially relates to a kind of electric-controlled load sensing proportion valve.
Background technology
Current SABS is to utilize the distance between vehicle body and vehicle bridge to change (external forces) to change the pretightning force of spring, increase along with car load, correspondingly it is adjusted, make can obtain the braking force distribution of an approximate ideal under any load-up condition, its main inductive component is spring, and what regulate proportioning valve piston movement is also spring, the braking force distribution effect that the proportioning valve of this spline structure can reach is not in short supply.
Utility model content
For solving the problems referred to above, the utility model proposes a kind of control accuracy high, the electric-controlled load sensing proportion valve that result of use is good.
This utility model be the technical scheme is that a kind of electric-controlled load sensing proportion valve, the proportion valve body on fixed mount and drive motor it is arranged on including fixed mount, and for detecting the pressure-detecting device of pressure between vehicle frame and back axle, and for controlling the programmable controller that drive motor rotates, the piston of described proportion valve body is connected to the tooth bar stretching out outside valve body, dust cover it is nested with outside tooth bar, the axle head of described drive motor extends in dust cover, and be provided with and the gear of tooth bar bonding in end, described programmable controller electrically connects with pressure-detecting device and drive motor.
Further, described programmable controller is arranged on fixed support, and electrically connects with automotive control system.
Further, the end of described proportion valve body is additionally provided with the guide rail for stationary rack.
Compared with prior art, it has the advantages that this utility model
Electric-controlled load sensing proportion valve of the present utility model have employed pressure-detecting device as sensing element, adopting the motion of motor regulating piston simultaneously, being precisely controlled proportioning valve thus effectively achieving, it is thus achieved that more reasonably braking force distribution effect.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and the embodiments, this utility model is further elaborated, should be understood to, detailed description of the invention described herein, only in order to explain this utility model, is not used to limit this utility model.
A kind of electric-controlled load sensing proportion valve as shown in Figure 1, the proportion valve body 2 on fixed mount 1 and drive motor 3 it is arranged on including fixed mount 1, and for detecting the pressure-detecting device 4 of pressure between vehicle frame and back axle, and for controlling the programmable controller 5 that drive motor 3 rotates, the piston of described proportion valve body 2 is connected to the tooth bar 6 stretched out outside valve body, dust cover 7 it is nested with outside tooth bar 6, the axle head of described drive motor 3 extends in dust cover 7, and be provided with and the gear 8 of tooth bar 6 bonding in end, described programmable controller 5 electrically connects with pressure-detecting device 4 and drive motor 3.During use, detecting pressure by pressure-detecting device 4 and transfer data to, programmable controller 5 controls drive motor 3 according to force value and operates to adjust accurately the piston movement of proportion valve body 2.
Wherein, described programmable controller 5 is arranged on fixed mount 1, and electrically connects with automotive control system；The end of described proportion valve body 2 is additionally provided with the guide rail 9 for stationary rack 6.
Electric-controlled load sensing proportion valve of the present utility model have employed pressure-detecting device as sensing element, adopting the motion of motor regulating piston simultaneously, being precisely controlled proportioning valve thus effectively achieving, it is thus achieved that more reasonably braking force distribution effect.
Embodiment described above is only that preferred implementation of the present utility model is described, and not design of the present utility model and scope is defined.Under the premise without departing from this utility model design concept; various modification that the technical solution of the utility model is made by this area ordinary person and improvement; protection domain of the present utility model all should be dropped into, the technology contents that this utility model is claimed, all record in detail in the claims.
