Abstract
The utility model relates to the field of automobile air pressure braking, particularly to an automobile air pressure SABS device which comprises an SABS bracket, an SABS assembly, a swing arm, a rubber connecting sleeve, a rubber coupling sleeve, a worm drive type hose clamp hoop, a transmission rod, an elastic arm and an elastic arm bracket, wherein the SABS assembly is fixed to the SABS bracket, and connected with the swing arm, and drives the swing arm to rotate; the elastic arm is fixed to the elastic arm bracket; the rubber connecting sleeve and the rubber coupling sleeve are fixed to the two ends of the transmission rod through the worm drive type hose clamp hoop; the rubber connecting sleeve is connected with the swing arm through a a pin shaft; the rubber coupling sleeve is connected with the elastic arm through a pin shaft. The automobile air pressure SABS device can effectively sense the change of a load, adjusts the braking force of a back shaft according to the change of the load, and improves the direction stability when an automobile brakes so as to improve the driving safety of the automobile.
Description
Technical field
The utility model relates to automobile pneumatic braking system field, relates to specifically a kind of automobile pressure load sensing proportioning valve gear.
Background technology
At present a lot of trucies are in order to reduce production costs, arrangement brake apparatus for adjusting force not mostly, because the empty fully loaded axle load of truck changes greatly, conventionally rear wheel brake braking force designs according to the needs of fully laden, but when zero load, rear axle load is less, it is less that rear axle adheres to braking force, larger rear brake braking force is easy to be greater than rear axle and adheres to braking force, cause trailing wheel prior to front-wheel locking, now, vehicle, as long as will easily there is the dangerous working conditions such as whipping in the situation that of side force, loses directional balance.Along with the day by day raising of people to automotive safety, it is very urgent that device to apply correction to braking force seems, load sensing valve is exactly a kind of good selection cheaply.
Utility model content
The purpose of this utility model is to address the above problem, and a kind of automobile pressure load sensing proportioning valve gear is provided.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of automobile pressure load sensing proportioning valve gear, comprise load sensing valve support, load sensing valve assembly, swing arm, rubber adapter sleeve, rubber coupling bush, scroll drive type flexible pipe clamp, drive link, elastic arm, elastic arm support, load sensing valve assembly is fixed on load sensing valve support, load sensing valve assembly is connected with swing arm and drives swing arm to rotate, elastic arm is fixed on elastic arm support, rubber adapter sleeve and rubber coupling bush are fixed on drive link two ends by scroll drive type flexible pipe clamp, wherein rubber adapter sleeve is connected with swing arm bearing pin, rubber coupling bush is connected by bearing pin with elastic arm.
The beneficial effects of the utility model are: thereby solved originally because flexible piece is connected with rigid pipe, produce the variation issue that moderate finite deformation can not more accurate perception load while moving, variation that can effectively perception load, axle braking force after regulating according to the variation of load, directional balance while having improved automobile brake, thus the driving safety of automobile improved.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation,
Fig. 2 is resilient arm structure figure,
Fig. 3 is not improved air pressure load sensing proportioning valve gear.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Embodiment: referring to Fig. 1, Fig. 2, Fig. 3.
A kind of automobile pressure load sensing proportioning valve gear, comprise load sensing valve support 1, load sensing valve assembly 2, swing arm 3, rubber adapter sleeve 4, rubber coupling bush 7, scroll drive type flexible pipe clamp 5, drive link 6, elastic arm 9, elastic arm support 8, load sensing valve assembly 2 is fixed on load sensing valve support 1, load sensing valve assembly 2 is connected with swing arm 3 and drives swing arm 3 to rotate, elastic arm 9 is fixed on elastic arm support 8, rubber adapter sleeve 4 and rubber coupling bush 7 are fixed on drive link 6 two ends by scroll drive type flexible pipe clamp 5, wherein rubber adapter sleeve 4 is connected with swing arm 3 bearing pins, rubber coupling bush 7 is connected by bearing pin 10 with elastic arm 9.
Load sensing valve support 1 is fixed on vehicle frame, and elastic arm support 8 is fixed on rear axle case.
Improve explanation: between the glue coupling bush 7 of originally common automobile pressure load sensing proportioning valve gear and elastic arm 9, be to be fixedly connected with, thereby because being connected when motion with rigid pipe, flexible piece produces the variation that moderate finite deformation can not more accurate perception load, making, to regulating rear axle braking force accurate not in time, affects driving safety.
What embodiment of the present utility model announced is preferred embodiment; but be not limited to this; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and variation, but only otherwise depart from spirit of the present utility model, all in protection domain of the present utility model.
