Description

Safety and steady device for light car

The present invention relates to car chassis, car body shell, each steering unit.

Running car is to advance forward or backward by the engine power driving front-wheel of automobile itself or trailing wheel promotion vehicle body drive wheel.Because the road surface recessed not gentle inclination in hole does not wait, automobile has tangible four sides to tilt in motion, particularly braking and more obvious when turning in running car, and the centnifugal force of the inertia of automobile brake and turning often makes the front portion of automobile and below, lateral tilt.This bevelled situation is to be dangerous uncomfortable again to the rider, and unforeseen circumstances such as also may occur wounding.

What is more important, automobile cause the force of collision all to concentrate on the front lower place of automobile when keeping straight on.

Vehicle in cornering with braking forces and self breaks away, and centrifugal force, the outside is downward-sloping equally, and the factor of certainly will cause collision, overturning is bigger, because the loss that above-mentioned two situations bring for people's lives and properties is just bigger.

There are two for addressing these problems common way:

One, utilizes steel spring that vehicle frame is connected as elasticity with car sedan-chair (or axletree), and absorb and impact that the buffering wheel is suffered under steam and tilt not make it directly to pass on the vehicle frame in order to avoid cause the strenuous vibration of vehicle frame and vehicle body and reduce the inclination of automobile.In order to make automobile and the passenger safety when colliding and overturn, a large amount of destructive tests has been done to the unitary construction of automobile by each auto vendor, and unsafe factor is carried out at corresponding improvement.Improved the safety and comfort performance of automobile.Want to improve the safety and comfort performance on this basis more very big difficulty will take place.

Two, " world inventions " publication, the volume first phase (total the 62nd phase) the 27th page title was mentioned the automobile suspension system that Britain La Tesi car company changes the automotive fittings that spring was arranged originally on no spring for " automobile suspension system of no spring " in 1987 the tenth, replacement the complicated sensor of a cover, computing machine and hydraulic machinery, vehicle body phase outer incline when having solved the insurmountable automobile turning of spring installation, tailstock perk during brake, the point of determining that headstock has a down dip, the method can solve the insurmountable problem of one really, but because the method manufacturing process complexity, involve great expense, the consumption automobile engine power is big, and general vehicle is difficult to implement this method.

The automatic rocking equipment that the purpose of this invention is to provide a kind of no consumption power, it can reduce effectively, and the running car uneven road surface tilts and the turning vehicle body outwards tilts tailstock perk during brake in the below.The situation that headstock has a down dip.Reduce manufacturing expense, no consumption engine power, certain safety and comfort performance that improves automobile effectively.

The object of the present invention is achieved like this: the propons of this device is and driving engine all-in-one-piece before driving armature assembly, it is connected with the after poppet assembly by bow type rocker, car body shell centre is connected with bow type rocker centre strut, car body shell seems a cradle that rocks like this, high back is low before the glancing impact, low outer high in during turning, do not make rider's body forward or outward-dipping, thereby improve the traffic safety and riding comfort of automobile.In addition, because unexpected the collision, make automotive front upright stop motionless, at this moment car body shell drive chaufeur and passenger impact forward, because the center connecting portion of car body shell connects on the centre strut of bow type rocker, so, the car body shell power of being used to forward forces the bottom of car body shell, front portion to be risen to the front upper place under the obstruction of centre strut, the power of being used to so forward becomes lift upwards, whole car body shell be used to the top that power rushes at knocked object, will alleviate personnel's injures and deaths by bus so greatly.So, the purpose of realizing ideal easily.

The present invention increases a front frame slide block mechanism newly, a bow type rocker, an after poppet slide block mechanism, hydro-leveling device because only need at former car (the before driving Shanghai Santana Car of driving engine and propons one) integral structure.Bow type rocker connects the front and back support slide block mechanism, and the centre strut of bow type rocker is connected with hydro-leveling device, and car body shell is connected with hydro-leveling device.

Various steering units change the hydraulic pressure transfer energy into, and newly-increased manual car body shell balancing device, automobile body shell control swing latching device, and this a series of steering unit does not need the power of driving engine, so make less complex.

Describe the concrete device operational detail situation that proposes according to the present invention in detail below in conjunction with each figure.

During automobile brake, the power of being used to of car body shell and bow type rocker concentrates on armature assembly and the after poppet assembly.Because the resistance of front and back support assembly, Fig. 5, front frame (16), Fig. 8, (23) two recoil spring compressions of after poppet slowly move ahead bow type rocker car body shell, while Fig. 5, landslide steel ball (10) on the bow type rocker oblique angle (9) is used to try hard to recommend down moving at bow rocker car body shell, steel ball (10) slides to the front upper place in the round-formed 50 heap shape concave volumes (8) of spending mostly along the front frame body, bow type rocker drives left and right sides slide block (4) (12) simultaneously, left and right sides slide block drive up and down slide block (3) (11) and spur spring (6) (14) at this moment the front end of bow type rocker raise.The rising of bow type rocker front end has remedied the height that glancing impact inertia is reduced front-wheel, antivibration spring compression, and the front end that makes the bow type pluck frame keeps the height of former brakeless state.Moreover Fig. 1, car body shell are the tops that is installed in the centre strut (4) of Fig. 7, bow type rocker by Figure 12, car body shell levelling gear, because the resistance of centre strut (4) makes the car body shell center can not be forward, the power of being used to of car body shell forces the bottom of car body shell by Figure 12, car body shell levelling gear and anteriorly tilts to the front upper place simultaneously.During automobile brake, car body shell is 15 degree to the maximum number of degrees that limit of front upper place bevelled; The destructive collision exceeds the qualification number of degrees.Thereby the power of being used to of advancing becomes upwards lift, makes passenger's insentience inertia forward, but only thinks that health is pressed on the seat reminds people automobile in braking.When automobile met accident collision, the resistance that automotive front is subjected to was bigger, and the anterior rising of car body shell is just high more dangerous just more little to the passenger.So, can improve the safety and steady performance of automobile really effectively.

During automobile turning, the outside centnifugal force of car body shell and bow type rocker shifts out main pseudosection (21) and Fig. 8, oblique angle (17) steel ball (11) by Fig. 5, oblique angle (9) steel ball (10) at A-A and outwards shifts out in the slope of main pseudosection (27) top at B-B and slide, and Fig. 5, anti-skidding latch (24) (25), Fig. 8 are arranged when sliding into the top.Anti-skidding latch (30) (31) will slide partly to block and prevent to skid off.Drive simultaneously Fig. 5, left and right sides slide block (4) (12) up and down the drop-down spring of slide block (3) (11) (6) (14) and Fig. 8, left and right sides slide block (6) (20) up and down the drop-down spring of slide block (8) (19) (7) (18) doing reasonably motion.This movement sequence raises the bow type rocker centnifugal force outside, the bow type rocker outside raises and has remedied centnifugal force when turning to the height that outside front-wheel, trailing wheel and the compression of front and back wheel antivibration spring are reduced, and makes the outside of bow type rocker centnifugal force remain on the height of former no turn condition; Moreover bow type rocker is subjected to outside action of centrifugal force of car body shell and the centnifugal force of self, under front and back support hinders, by Figure 12, car body shell levelling gear, force the bottom of car body shell and the bottom one of bow type rocker to tilt top, the centnifugal force outside in the same way, maximum inclination is 15 degree on the lateral of automobile turning centnifugal force.Thereby outside centnifugal force becomes lift upwards.Because above-mentioned state, improved turning speed, reduced the brake weight of glancing impact, the sideslip situation when having reduced brakeing during cornereing, reduced oil consumption, prolonged the service life of brake system, reduced the centnifugal force of turning and the factor that brakeing during cornereing breaks away and causes overturning, collides, made the outside centnifugal force of passenger's insentience simultaneously, and only think that health is pressed on the seat, the reminds people automobile is being turned, so, can improve the safety and steady performance of automobile really effectively.

This device can solve vehicle starting equally and cause backward inertia.Automobile is 8 degree to the back upper place maximum inclination.Can say so: the light car of apparatus of the present invention is housed, resembles a smooth and slick cradle that rocks under steam.

Because the application of the present invention on automobile, the inconvenience of bringing connecting device for each steering unit of automobile, in order to make application of the present invention, in automobile operation mechanism, done corresponding change, and original direct control mechanism, become and indirect transmit energy, and finish the required various functions of each mechanism with high pressure rubber hose.

According to concrete device of the present invention, typically structure example and the accompanying drawing with each manipulation provides.

Below each figure be the operational detail situation of the concrete device of each steering unit that proposes according to the present invention:

Figure 17, be that center section plan is looked on the left side of wheel hand brake operation mechanism and car body shell balancing brake steering unit.This device comprises: car body shell balancing brake handle (4) makes the oil in the oil cylinder (7) extrude from oil outlet pipe (2) (3) when pulling handle (4) drives tappet (8) promotion piston (6) compression spring (5) by fulcrum pin (13).Oil outlet pipe (2) is to be connected on Fig. 5, oil pipe (7) (15) and Fig. 8, oil pipe (4) (22) respectively; Oil outlet pipe (3) is the control mechanism (7) [details drawing does not draw among the figure] that is connected on the band friction lining of Figure 12, the swing of control car body shell.Because the oil pressure in the pipeline forces each control mechanism to finish the control task of each one, the passenger does not steadily shake to make car body shell reach when stopping up and down.

When driving wheel braking pull bar (11) by fulcrum pin (13), the pulling hand braking handle of wheel (1) makes the wheel braking mechanism braking.

Because wheel is a brake-applying handle (1) is same fulcrums with car body shell balancing brake handle (4) two handles, same orientation, but varying length, when parking pulls a cart to take turns brake-applying handle (1), must together spur car body shell balancing brake handle (4), this wheel braking handle (1) can not use separately, and car body shell balancing brake handle (4) can use separately because under steam under the automobile steep slope prevent anterior raise to influence under the sight line in chaufeur the place ahead and the certain conditions need to spur car body shell balancing brake handle (4).As: meet to turn, when crossing narrow road in case automobile rocks super wide.
