The specific embodiment

The installation of the anterior lifter in chassis as shown in Figure 2, lifter is installed between preceding trailing arm and the crossbeam 20, the corner of wherein preceding trailing arm and crossbeam flexibly connects with a hinge 26, and also be provided with a lifter lower bracket 22 on the preceding trailing arm, on crossbeam 20, also be provided with a lifter upper bracket 21, lifter 14 is located between the lower bracket, and and last lower bracket between flexibly connect with hinge 26.A spring cun frame 17 is captiveed joint with preceding trailing arm, and the spring 18 that is used as cushioning effect is installed between spring cun frame 17 and the suspension 19.When regulating chassis height, the position of suspension 19 relative wheels 16 still there is not change, and spring 18 length there are not change yet.So the chassis rises and falls running car all there is not influence.Lifter 14 is converted by the high-quality screw type mechanical jack of car, when lifter 14 the transmission shaft output shaft that is decelerated device 8 when driving, can still be the hand of rotation that backing car gear changes the transmission shaft that drop-gear box 8 driven just by the extension gear that advances, and then the subtended angle size of regulating 20 on trailing arm 23 and crossbeam specifically is to rise or fall with regard to the may command chassis, realizes that chassis height regulates.

Rear portion, chassis lifter is installed as shown in Figure 3: lifter 14 is installed on the lifting transition frame 24, and lifting transition frame 24 1 ends connect with crossbeam 20, and the other end flexibly connects with lifter 14, and middle and spring 18 flexibly connects.Between crossbeam and trailing arm, spring 18 two ends connect lifting transition frame 24 and trailing arm 23 respectively, flexibly connect with a hinge 26 between lifting transition frame 24 and the crossbeam 20, trailing arm 23 also and between the crossbeam 20 flexibly connects with hinge 26, lifter upper bracket 21 is installed on the crossbeam 20, and lifter lower bracket 22 is installed on the lifting transition frame 24.Lifter 14 is installed between lifter upper bracket and the lower bracket, and and last lower bracket between for flexibly connecting.

As shown in Figure 1, be located at feather key 5, chute 6, the gear 7 on vehicle transmission shaft clutch top successively; With establish a telescopic feather key 5 behind the universal-joint 11 of driving engine 4 bonded assembly propeller-shafies 36, this feather key uses spline, and in the middle of universal-joint 11 and spline, establish the fixed mount 2 that a tape spool holds, also the forebody at propeller-shaft 36 sets up a Control of Automobile transmission shaft 36 anterior flexible chutes 6 separately, control stalk 1 is installed on the fixed mount 2 of propeller-shaft one side, and act on the chute 6, on power-transfer clutch top, gear 7 of corresponding stationkeeping under the chute, establish the sliding support 10 that a tape spool holds at gear 7 rears, the fixed mount 2 of this support after in conjunction with universal-joint 11 makes propeller-shaft 36 leading portions flexible on trapped orbit.The below of power-transfer clutch 9 also is provided with the fixed mount that a tape spool holds in the latter half of propeller-shaft 36, and this fixed mount makes two joints of power-transfer clutch keep alignment constantly in conjunction with two fixed mounts of front portion.When power-transfer clutch be in bonding state be propeller-shaft cog 7 with driven gear 13 be in disengaged condition.Since fulcrum on the fixed mount and control stalk 1 terminal the flexible connection, thus make spline shrink by just promoting chute 6 forward with hand adjustment joint control stalk, gear 7 and driven gear 13 engagements, 9 two splice failures of power-transfer clutch.When start the engine 4, propeller-shaft 36 leading portions begin rotation, gear 7 on the propeller-shaft drives driven gear 13 and rotates, and driven gear 13 rotates with the output shaft connection of retarder 8 and then the transmission shaft that drives on former and later two lifters 14, thereby has just realized the function of chassis lifting.Otherwise, also can gear 7 and driven gear 13 be thrown off after finishing the lifting task by lever for adjusting oil 1, two joint engagements of power-transfer clutch, recovered the function of propeller-shaft drive rear-axle drive, for the corresponding precision of regulating power-transfer clutch and propeller-shaft cogs and retarder on the corresponding precision of driven gear, be provided with leading screw screw 3 on adjust bar, the degree of tightness of available adjustment leading screw screw is regulated the corresponding precision between the above-mentioned part.

Sensing limiting device keystone configuration is: shell 27 and the portable bar 33 that is enclosed within the shell, portable bar 33 can be free to slide flexible in the enclosure.A side is fixed with a resistance board 28 in the shell, and this resistance board links to each other with a lead, opposite side is then being fixed a non-resistance conductive plate 29 in the shell, also be provided with two contacts in the upper end of portable bar, and establish light spring 35 in the groove at contact place, guarantee the electroplax contact of contact with both sides.Stop to continue lifting when guaranteeing to be elevated to certain height on the chassis, non-resistance conductive plate 29 two ends are shorter than resistance board 28 two ends when design, the loop that contact 1, non-resistance conductive plate 29 and propulsion source form by lead, the two ends that the contact 1 on portable bar right side will be crossed non-resistance conductive plate 29 when the chassis rises or drops to certain limit, be that contact has just broken away from the non-resistance conductive plate, thereby C/LOOP has originally just disconnected, driving engine 4 has not just changeed, and chassis height just can keep no longer continuing rising or falling.In order to get more information about the height of chassis lifting, with the height of the corresponding lifting of reading of amperemeter/ammtr, the adjustable height on chassis is recognized in contact 2 32, amperemeter/ammtr, 12V power supply formation loop like this by the variation of this loop current in the lifting process of chassis.
