Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
Be illustrated in figure 1 the structure principle chart of vehicle of the present utility model and lateral stability lever system thereof, as seen from the figure, this system comprises vehicle body, suspension and the lateral stability lever system be arranged between vehicle body and suspension, this lateral stability lever system comprises the Panhard rod 2-2 for being arranged on corresponding suspension and is arranged at the hydraulic ram 3 of Panhard rod at least one end, Panhard rod is a complete U-shaped bar structure, by bearing 2-1 and vehicle bridge 1, (dependent suspension is vehicle bridge for it, independent suspension is lower swing arm or the oscillating arm bracket of nonspring carried mass, subframe) connect, hydraulic ram 3 is for driving Panhard rod 2-2 to carry out corresponding actions by piston rod.Two oil cylinder structure of hydraulic at Panhard rod two ends are identical, now only one of them hydraulic ram and control mechanism thereof are described, embodiment shown in Fig. 1 is that one-sided (left side) drives, one end of Panhard rod 2-2 hinged with the piston rod of hydraulic ram 3 (certainly by transmission device carry out being connected also can), the other end by a suspension rod 2-3 directly and vehicle body (i.e. vehicle frame) be connected.The hydraulic fluid port of this hydraulic ram is connected with oil circuit control, this oil circuit control be used for making hydraulic ram vehicle in little rolling condition time be in free state, described little rolling condition is the state of vehicle when the roughness pavement slightly risen and fallen or smooth-riding surface travel; And vehicle in large rolling condition time make hydraulic ram be in locked state, described large rolling condition is turn inside diameter or the state when jolting road traveling.
Embodiment 1
As shown in Figure 2, hydraulic ram in the present embodiment has rodless cavity and rod chamber, rodless cavity and rod chamber are respectively equipped with a hydraulic fluid port, and oil circuit control comprises control cock 4-1,4-2 set on the connection oil circuit of each hydraulic fluid port and the oil storage energy storage 6 set by the end being respectively connected oil circuit.
Embodiment 2
As shown in Figure 3, hydraulic ram in the present embodiment has rodless cavity and rod chamber, the middle part setting position (the present embodiment is midway location) of rodless cavity, rod chamber and this hydraulic ram is respectively equipped with a hydraulic fluid port, as shown in Figure 5, the hydraulic fluid port of rodless cavity A, rod chamber B and middle part setting position is respectively P1, P3, P2, P1, P2, P3 hydraulic fluid port is communicated with energy storage 6 respectively by respective oil circuit, and on the oil circuit of P1, P3 hydraulic fluid port, correspondence is provided with cone valve type solenoid directional control valve 4-1,4-2.
For ease of realizing automatic control, above-mentioned control cock is all adopted as the cone valve type solenoid directional control valve for turning on and off according to vehicle running state information, each electromagnetic valve is all connected with entire car controller ECU, ECU Real-time Collection vehicle traveling information, comprise the speed of a motor vehicle, steering wheel angle, lateral acceleration, car body side inclination angle etc., control the break-make of each electromagnetic valve.
Principle of work of the present utility model and process as follows:
(1) when road conditions are the roughness pavement or smooth-riding surface that slightly rise and fall, vehicle body is in little rolling condition, for ensureing the traveling comfort of vehicle, ECU is by comprehensively analyzing the speed of a motor vehicle, steering wheel angle, lateral acceleration and car body side obliquity information, control cone valve type solenoid directional control valve 4-1 and 4-2 energising (or power-off, depending on different valve model), a position conducting of two electromagnetic valves.The piston rod of hydraulic ram 3 is not lockable, and with oil cylinder desired location for balance position freely up and down slides within the specific limits, and the fluid of oil cylinder upper and lower cavity can free-flowing in the two directions; And now piston rod with the inclination by a small margin of vehicle body free-extension, Panhard rod 2-2 not bearing load, roll rate is lower, and namely now lateral stability lever system is inoperative, thus effectively lowers the angle of roll vibration of vehicle, improves riding comfort.
(2) when turn inside diameter or when travelling on road surface of jolting (road conditions are poor), vehicle body is in large rolling condition, for ensureing the safety of vehicle, ECU is by comprehensively analyzing the speed of a motor vehicle, steering wheel angle, lateral acceleration and car body side obliquity information, control cone valve type solenoid directional control valve 4-1 and 4-2 power-off (or energising, depending on different valve model), the b position conducting of two electromagnetic valves.Piston rod at ad-hoc location or middle part setting position by locking, now because piston rod is lockable, Panhard rod bearing load, the rigidity of stabilizer rod self is added up, and improve the safety of vehicle, lower mask body point different situations are illustrated:
I, when adopting the hydraulic ram of Fig. 2 and oil circuit control structure, no matter which kind of position to implement locking action in, then piston rod all can at ad-hoc location residing at that time by locking;
II, when adopting the hydraulic ram of Fig. 3 and oil circuit control structure, if cone valve type solenoid directional control valve 4-1 and 4-2 closes, fluid can only flow back to oil cabinet by the oil circuit of midway location (P3 hydraulic fluid port).No matter now which kind of position to implement locking action in, piston rod all can be got back to middle part setting position and be lockable, and makes a concrete analysis of as follows:
1. as shown in Figure 6, when implementing locking action, if piston is positioned at midway location top, now fluid enters cylinder upper cavity oil by the b position of solenoid directional control valve 4-1, the fluid of piston lower portion can flow back to oil storage energy storage 6, so piston still can move downward by the oil circuit that is bi-directionally connected of hydraulic fluid port P3.When piston movement is to desired location, after being blocked by hydraulic fluid port P3 herein, the fluid of piston lower portion cannot flow out again, piston ceases movement, and piston rod is lockable at this desired location, as shown in Figure 8.
2. as shown in Figure 7, when implementing locking action, if piston is positioned at midway location bottom, now fluid enters oil cylinder cavity of resorption by the b position of solenoid directional control valve 4-2, the fluid of upper piston area can flow back to oil storage energy storage 6, so piston still can upward movement by the oil circuit that is bi-directionally connected of hydraulic fluid port P3.When piston movement is to desired location, after being blocked by hydraulic fluid port P3 herein, the fluid of piston lower portion cannot flow out again, piston ceases movement, and piston rod is lockable at this desired location, as shown in Figure 8.
If Fig. 4 is the structure that lateral stability lever system is all installed in vehicle front and back end, and be only side and install additional, the utility model is not limited to the situation that above-described embodiment is mentioned, in other embodiments: only can install above-mentioned Panhard rod system at anterior or rear portion, the structure of certain lateral stability lever system can be that both sides all arrange hydraulic ram driving or only arrange the simple deformation being the utility model scheme in side.In addition, the mounting means of Panhard rod and oil cylinder and vehicle frame also can conversely, and the straight bar part by Panhard rod is connected with vehicle frame, and the knee part of U-shaped bar is connected with vehicle bridge.
Above embodiment only understands core concept of the present utility model for helping; the utility model can not be limited with this; for those skilled in the art; every according to thought of the present utility model; the utility model is modified or equivalent replacement; any change done in specific embodiments and applications, all should be included within protection domain of the present utility model.
