Abstract

The utility model discloses a vehicle suspension, which comprises an elastic element and a guide mechanism. The vehicle suspension has the key improvement that the elastic element is in inclined arrangement, in addition, the lower end of the elastic element is at the front part, and a pressure center line of the elastic element forms a 5-20-degree included angle with the vertical plane of an axle of wheels. The vehicle suspension has the advantages that the elastic element in the suspension is arranged in a backwards inclined structure, the lower end of the elastic element is at the front part, in addition, the pressure center line of the elastic element forms a certain included angle with the vertical plane of the axle of the wheels, in the vehicle running process, when a vehicle body ascends or descends, the elastic element releases energy to the wheels along the pressure center line of the elastic element, the thrust force generated on the wheels can be decomposed into the downward component force and the forward component force on the wheels, the downward component force acts on the downward wheel pressing, the ground griping performance is ensured, the forward component force can push the wheels to roll, the automobile weight is changed into the running motive power, and the energy saving goal is realized.

Description

A kind of vehicle suspension

Technical field

The utility model relates to a kind of vehicle key mechanism, particularly a kind of vehicle suspension.

Background technology

Suspension is the general name of the vehicle frame and all the power transmission connecting devices between vehicle bridge or the wheel of automobile; Its effect is power and the moment of transfer function between wheel and vehicle frame; And buffering is passed to the impulsive force of vehicle frame or vehicle body by uneven road surface; And the vibrations that decay and cause thus, can go to guarantee automobile smooth-goingly; Certainly also not only on automobile, use to some extent, on the front-wheel of three-wheel vehicle and two-wheel car, also use elastic element as shock attenuation unit, only structure is different; Vehicle suspension in general sense comprises that the representative type suspension frame structure is made up of elastic element, guiding mechanism and shock absorber etc., and discrete structure then also has bump rubber, Panhard rod etc.Elastic element has forms such as steel spring, air bellow, coil spring and torsion bar spring again, and the Modern Car suspension adopts coil spring and torsion bar spring more, and indivedual luxury cars then use air bellow; Elastic element in the suspension that uses at present is set to vertical or leans forward; The vertical meaning is exactly the vertical plane that the center of pressure line of elastic element is positioned at the wheel shaft place of wheel; The meaning that leans forward is exactly between the vertical plane at wheel shaft place of center of pressure line and wheel of elastic element certain included angle to be arranged, and the upper end of elastic element is preceding, the lower end after; It mainly acts on is exactly to absorb the downward impact of vehicle body; Release stored energy when lifting on the vehicle body is guaranteed the earth-catching property of wheel, guarantees the vehicle smooth-ride.

The utility model content

The utility model technical matters to be solved provide a kind of can with under the vehicle body towards the time be stored in Conversion of energy in the elastic element for wheel is had the vehicle suspension of impetus forward.

The design concept of the utility model is such; The effect of the elastic element in the vehicle suspension is the vehicle kinetic energy that produces towards the stage that jolts is down stored; Discharge at ascent stage; Guarantee the earth-catching property of wheel; The utility model is exactly when utilizing angle between the vertical plane at elastic element and wheel hub place that vehicle body is risen or descends traffic blows power to be changed into wheel downward power and power forward, makes elastic element to wheel generation impetus forward, and vehicle weight is changed into driving dynamics.

For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of vehicle suspension comprises elastic element and guiding mechanism; Its key improvements is: said elastic element be obliquely installed and its lower end preceding, the angle between the vertical plane of its center of pressure line and wheel hub place is the 5-20 degree.

Said elastic element is a coil spring, and the angle between the vertical plane at helical spring center of pressure line and wheel hub place is the 10-20 degree.

Said elastic element is a steel spring, and the angle between the vertical plane at the center of pressure line of steel spring and wheel hub place is the 5-15 degree.

Said elastic element is an air bellow, and the angle between the vertical plane at the center of pressure line of air bellow and wheel hub place is the 10-20 degree.

Adopt the beneficial effect that technique scheme produced to be: the elastic element in the suspension is arranged to the hypsokinesis structure, and its lower end is preceding, and between the vertical plane that belongs to of the center of pressure line of elastic element and wheel hub certain angle arranged; In the vehicle ' process, when vehicle body rose or descend, elastic element released energy along its center of pressure alignment wheel; To the impulsive force of the generation of wheel can resolve into to wheel downwards with forward two component; The effect of component downwards is the wheel of delaying unloading downwards, guarantees its earth-catching property, and component forward can promote wheel rolling; Vehicle weight is become driving dynamics, realize purpose of energy saving.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.

Fig. 1 is the structural representation of the utility model embodiment 1;

Fig. 2 is the structural representation of the utility model embodiment 2.

Vehicle frame in the accompanying drawings, 1; 2, connect support; 3, steel spring; 4, vehicle bridge; 5, coil spring; 6, suspension arm; A and b are the angle between elastic element center of pressure line and the wheel hub place vertical plane.

The specific embodiment

Embodiment 1, and a kind of vehicle suspension as shown in Figure 1 comprises elastic element and guiding mechanism; Its key improvements is: said elastic element be obliquely installed and its lower end preceding, the angle between the vertical plane of its center of pressure line and wheel hub place is the 5-20 degree.

Said elastic element is coil spring or air bellow; In concrete installation application process; Can be with Shock absorber and elastic element aggregate erection, its angle of inclination is identical, and the angle between the vertical plane at the center of pressure line of coil spring or air bellow and wheel shaft place is the 10-20 degree.

Embodiment 2, and a kind of vehicle suspension as shown in Figure 2 comprises elastic element and guiding mechanism; Its key improvements is: said elastic element be obliquely installed and its lower end preceding, the angle between the vertical plane of its center of pressure line and wheel hub place is the 5-15 degree.Said elastic element is a steel spring, and steel spring generally is applied to than on the full size vehicle, and it can use separately, and the upper end is connected with vehicle carriage, and the lower end can directly be connected with vehicle bridge also can play the effect of decomposing cushion effect.

Elastic element in the suspension is arranged to the hypsokinesis structure, and its lower end is preceding, and between the vertical plane at the center of pressure line of elastic element and wheel hub place certain angle arranged; In the process of moving, when vehicle body rose or descend, elastic element released energy along its center of pressure alignment wheel; To the thrust of the generation of wheel can resolve into to wheel downwards with forward two component; The effect of component downwards is the wheel of delaying unloading downwards, guarantees its earth-catching property, and component forward can promote wheel rolling; Vehicle weight is become driving dynamics, realize purpose of energy saving.
