Description

For the independent rear suspension of vehicle wheel

Technical field

The utility model relates to haulage vehicle engineering field and is intended to be mainly used in the types of transportation of three-wheel and four-wheel (tricycle, carriage and automobile).

Background technology

Vehicle hanging is for guaranteeing to have elasticity between vehicle body (vehicle frame) and its wheel and connect, reduce the dynamic load on body and wheel and its vibration and carry out in motion the combination of the element of body position adjusting of decaying. Maximum drive safety (it must resist the rollover of vehicle, and sufficient intact stability must be provided), trafficability (overcoming the ability of different obstruct) must be provided and determine the smooth-ride of driving comfort as the suspension of the intermediate connecting rod between vehicle body and road.

A well-known independent rear suspension for vehicle wheel is the independent rear suspension for CLEVER tricycle (for the compact low emission vehicle of urban transportation), and it is to be developed by one group of Germany scientist of Berlin University of Science and Technology. This known tricycle hangs (front-wheel and two trailing wheels) and guarantees that trailing wheel moves up and down on towing arm along body in the time that body tilts. Automatic hydraulic driver is controlled body in the inclination of sharp turn and the motion of wheel upwards in the time moving to road barricade, and in the time of vehicle stop, controls wheel.

The CLEVER tricycle body that the described independent rear suspension for vehicle wheel makes to have wheel shaft and wheel has that elasticity is connected, enough travelling and stability stably, but its technical burden is automation and hydraulic means, this is complicated and expensive because of it.

Another known independent suspension for vehicle wheel is described at the description of Russian Federation's patent of invention #1430300 of on 04 26th, 1985 that on October 15th, 1988 announces, and its International Classification of Patents index is B60G3/00 (applicant: the KOMMUNAR automobile factory of pricking POLO day).

The described independent rear suspension for vehicle wheel (vehicle-ZaporozhetsZAZ-968M) has two towing arms, each is all equipped with shock absorber strut and main assemblage of spring, the bottom pivot joint of one side and body, and opposite side is through the top pivot joint of shock absorber strut and main assemblage of spring and body. In the front hole of the arm of described suspension, there is the rubber bushing of depressing, it is connected by two bolts and two brackets that suspension are fastened to body bottom (car body floor). The pillar with extension shocker and spring serves as the flexible member of suspension. Damper is for required to the damping of body generation of vibration, and described damping is to be realized by occurred resistance in the time that a cavity flow to another cavity by calibration hole when the liquid in damper. Flexible member is for weakening the shock and vibration that pass over from road. In described suspended structure, lower spring end leans against on the plate that is soldered to damper body and upper end leans against by lining and nut and is crushed on the plate on absorber rod. Two of bottoms rubber bushing and a dividing bush of damper are secured to suspension bracket by packing ring and bolt, and its top is secured on the support that is soldered to body top. The moving up of car is limited to rubber bumper and its and moves down and be limited to special shackle.

The described independent rear suspension for vehicle wheel cannot make it enough comfortable and safe, this is because it cannot guarantee to travel stably and high stability,, in the time that it moves on quite rugged road or when wide-angle tilt or in the time that sharp turn is handled, it cannot prevent vehicle rollover. Considerable vibration is also sent to body from wheel in the situation that fully decaying without mistake.

One end of described suspension is directly fastened to vehicle body by rigidity, and because it exists, the vertical mobile only actually of arm is to provide by damping and the cushioning effect of shock absorber strut and main assemblage of spring, and this proves that it is not enough to provide high stability. Consider that moving up and down during vehicle travels with described suspended structure of towing arm is restricted, large road jolt (more than 30cm) or 45 degree more than slope place wheel there is not enough vertical displacements, this is subjected to displacement the center of gravity of vehicle in the direction on slope, thereby makes inclination of vehicle and finally turn on one's side. In addition, described suspension embodiment cannot offset centrifugal force at sharp turn rightly, and this is because it does not allow body to change to a large extent its position to shift its center of gravity and to prevent rollover with respect to road.

In technical spirit and technological achievement, immediate situation is the independent rear suspension for vehicle wheel described in the application of patent application for obtaining Ukraine invention #a201210690 (submitted on 09 12nd, 2012, its International Classification of Patents index is B60G3/00 and B60G21/00).

The described independent rear suspension for vehicle wheel has two towing arms that are provided with shock absorber strut and main assemblage of spring. One side of arm and the bottom pivot joint of body, its opposite side is through shock absorber strut and the main assemblage of spring of pivot joint and be positioned at the top pivot joint of the equiarm rocking bar and the body that are fastened on pivotally body top on the position of wherein entreating on longitudinal axis.

In described suspension, in the time that a rising in vehicle wheel is moved when overcoming the rugged situation of road or on vehicle has the road of sizable side slope, kinetic energy is passed to shock absorber strut and main assemblage of spring by arm from wheel. Power is passed in the arm that starts the mobile rocking bar pivotly joining, be that its body with respect to another arm that power is passed to the rocking bar that promotes another shock absorber strut and main assemblage of spring is turned with certain angle, thereby make its decline and through arm, wheel be depressed into road. Structure is determined the simultaneous interconnection of wheel, with and to the connection of vehicle body, wherein vehicle body provides the movement that moves required vehicle wheel on sizable obstacle, and make vehicle body with respect to the plane of road on vertical position. By this way, by rigidly attached shock absorber strut and main assemblage of spring to the rocking bar of body, vehicle is realized to damping by being connected to through hinged joint.

The arm of rocking bar is fixed to body, so that described structure increases rigidity, when vehicle mobile or when static, in vertical vehicle body position, needs this rigidity.

In the time that arm is fixed to body, the shock absorber strut of described suspension is rejected from damping period, and impact be directly passed to body, this is admissible for vehicle stop and Parking condition, but this is undesirable under steam, this is because it has caused the loss of stationarity. In the time that rocking bar is fixed, hang and keep damping, but vehicle has lost rigidly fixing in vertical position, and due to the function of the unwanted effect of generation of shock absorber strut, particularly when height of car with respect to its width compared with large and while thering is vehicle rollover dangerous, some lateral vibrations may occur.

Therefore, the described known independent rear suspension for vehicle wheel does not have enough comfortablenesses and security, and this is because it cannot provide cruising characteristic and high stability.

Utility model content

The utility model is to develop a kind of independent rear suspension for vehicle wheel based on this object, wherein by introducing element and new element and the new connection between element of original exploitation, between vehicle wheel and its body, being provided with elasticity connects, thereby its impact that can not be subject to the structural detail of fixed vehicle makes structure increase rigidity in motion, and in static state, make body on vertical position, consequently obtained travelling more stably and higher stability of vibration do not occur, this makes vehicle have comfortableness and security.

The object setting is by obtaining for the independent rear suspension of vehicle wheel, it comprises two towing arms with wheel, be provided with pillar, the bottom pivot joint of one side and body, and opposite side is through the end of pillar and equiarm rocking bar and two dampers and main assemblage of spring pivot joint, according to the utility model, between the towing arm with wheel, central towing arm is installed on the transversal line identical with it, the bottom pivot joint of one side and body, and opposite side is through the top pivot joint of damper and main assemblage of spring and body, the middle body of equiarm rocking bar is attached to central towing arm pivotally.
