Technical field
The utility model belongs to a kind of sense mounted mechanism of vehicle balance suspension, relates generally to the sense mounted mechanism of guiding rod-type balance suspension.
Background technology
The sense mounted mechanism of the balance suspension that has occurred in the market, wherein as shown in Figure 1 a kind of, support 3 is fixed on the bridge 1, support 4 is fixed on the bridge 2, and load sensing valve 14 is fixed on the vehicle frame 15, and an end of straight-bar 5 is connected with support 3 with hinge 9, straight-bar 6 one ends are connected with the other end of straight-bar 5 with hinge 10, the other end is connected with support 4 with hinge 11, and the middle part of straight-bar 6 is connected with an end of straight-bar 7 with connecting hinge 12, and the other end of straight-bar 7 is connected with load sensing valve fork 8 with bearing pin 13.
The said mechanism number of parts is many, the structure more complicated, and the free space between the guiding rod-type balance suspension is smaller, is inconvenient to arrange.And number of parts is many, has increased cost, has reduced reliability.
Summary of the invention
In order to solve the sense mounted mechanism complex structure of existing balance suspension, the problem of being inconvenient to arrange on guiding rod-type balance suspension the utility model proposes a kind of balance suspension sense mounted mechanism of installing of arranging simple in structure, convenient on balance suspension.
For this reason, the utility model achieves the goal based on following inventive concept: adopt the wire drawing assembly to substitute the existing link member of feeling in the mounted mechanism, control load sensing valve with the wire drawing assembly as driver element.
The utility model derives two kinds of technical schemes under the framework of a common inventive concept.
Technical scheme one: balance suspension sense mounted mechanism, its load sensing valve directly are fixed on the vehicle frame, are respectively equipped with fixed support on two vehicle bridge, it is characterized in that: described sense mounted mechanism also comprises the wire drawing assembly, and the wire drawing assembly is made up of wire drawing, wire drawing sheath; Wire drawing sheath two ends are separately fixed on the described fixed support, and wire drawing one end is fixed on the fork of load sensing valve, and the other end is fixed on one and connects on the support; Connecting support is fixed on the vehicle frame.
Technical scheme two: balance suspension sense mounted mechanism, its load sensing valve directly is fixed on the vehicle bridge, be respectively equipped with two and the cooresponding fixed support of axle positioning on vehicle frame, it is characterized in that: described sense mounted mechanism also comprises the wire drawing assembly, and the wire drawing assembly is made up of wire drawing, wire drawing sheath; Wire drawing sheath two ends are separately fixed on the described fixed support, and wire drawing one end is fixed on the fork of load sensing valve, and the other end is fixed on one and connects on the support; Connecting support is fixed on another vehicle bridge.
The summary the beneficial effects of the utility model are as follows: adopt described balance suspension sense mounted mechanism, motion all around takes place in vehicle bridge, passes to load sensing valve by wire drawing.When load change, the suspension height changes, the corresponding variation takes place in the distance of two vehicle bridge and frame brackets, cause wire drawing and wire drawing sheath generation relative motion, the fork angle of load sensing valve changes thereupon, thereby the adjusting brake-pressure reaches the insensitivity of automobile under the deceleration/decel of various load.The utility model is compared with the sense mounted mechanism of existing structure, and is simple in structure, number of parts is few, only needs a wire drawing assembly and three supports, and the wire drawing arrangement of components is more random, and convenient the installation suits to use on guiding rod-type balance suspension especially; Substitute the link member in the existing structure with a wire drawing assembly, when guaranteeing reliability, reduced cost.
Below by the drawings and the specific embodiments and the utility model is elaborated.

The specific embodiment
Be a kind of embodiment structural representation of balance suspension sense mounted mechanism as shown in Figure 2, the wire drawing assembly is made up of wire drawing 16, wire drawing sheath 17.Fixed support 3 is fixed on the vehicle bridge 1, and fixed support 4 is fixed on the vehicle bridge 2, and wire drawing sheath 17 1 ends are fixed on the fixed support 3, and the other end is on fixed support 4.Wire drawing 16 1 ends are fixed on the fork 8 of load sensing valve, and the other end is fixed on and connects on the support 18, connects support 18 and is fixed on the vehicle frame 15, and load sensing valve 14 also is fixed on the vehicle frame 15.No matter the motion that vehicle bridge 1 and vehicle bridge 2 take place all around, the wire drawing assembly can guarantee its motion needs, when load change, the suspension height changes, vehicle bridge 1, the corresponding variation takes place in the distance of vehicle bridge 2 and vehicle frame 15, causes wire drawing and wire drawing sheath generation relative motion, change the angle of the fork of load sensing valve, thereby regulate brake-pressure.
Be the structural representation of load sensing valve as shown in Figure 3,20 is admission port, and 21 is air extractor duct, 22 is exhausr port, and 23 are the control mouth, when load sensing valve is installed on the vehicle frame, fork 5 is connected with certain attachment point on the vehicle frame by elastic arm, and fork 5 can rotate around A, and α=60 ° are fully loaded position.When unloaded, fork 5 is in extreme lower position, the pressure minimum of delivery port.Along with loading, fork 8 moves to fully loaded locality from zero load, and respective change takes place α, and delivery port pressure becomes greatly gradually, the at full load maximum.Like this, load sensing valve can be along with the variation of automobile load, fork 8 angle [alpha] generation respective change, and automatically regulating air chamber air pressure adapts to guarantee rate of braking and axle load.Thereby reach the insensitivity of automobile under the deceleration/decel of various load.
As shown in Figure 4, when load increases, distance between vehicle bridge 1, vehicle bridge 2 and the vehicle frame 15 shortens, wire drawing 16 be connected support 18, loosen at fork 8 bonded assembly two ends, substantially there is not relative motion between wire drawing 16 and the wire drawing sheath 17, fork 8 is upwards swing under the effect of elastic force, and angle increases, thereby increases braking pressure.
As shown in Figure 5, when the road surface was uneven, vehicle bridge 1 moved downward, this end elongation of wire drawing 16; Vehicle bridge 2 upward movements, this end wire drawing of wire drawing 16 shortens; Wire drawing 16 produces relative motion with wire drawing sheath 17, and fork 8 angles of load sensing valve are constant, and brake-pressure is constant.
Fig. 6 is the another kind of embodiment of the utility model balance suspension sense mounted mechanism.Fixed support 3, fixed support 4 are fixed on the vehicle frame 15, and wire drawing sheath 16 1 ends are fixed on the fixed support 3, and the other end is fixed on the fixed support 4.Wire drawing 16 1 ends are fixed on the fork 8 of load sensing valve, and the other end is fixed on and connects on the support 6.Connect support 6 and be fixed on the vehicle bridge 2, load sensing valve 14 is fixed on the vehicle bridge 1.Obviously, load sensing valve 14 also can be installed on the vehicle bridge 2, connects support 6 and is fixed on the vehicle bridge, and its action effect is consistent.
In conjunction with Fig. 2, shown in Figure 6, the fixed support 3 in the sense mounted mechanism shown in Figure 6, fixed support 4, load sensing valve 14, connect the installation site of support 6 and shown in Figure 2 variation taken place, the annexation of wire drawing assembly is constant, but the purpose effect is identical.
