Background
Wheel vehicles are generally divided into front drive and rear drive, if the vehicle is the rear drive, the static friction force of the rear wheels provides forward power, and the static friction force of the front wheels prevents forward movement. The wheels are round, because rolling friction is much less than sliding friction. The contact surface is hard and the tire air is sufficient during the running process, so that the rolling friction couple moment can be reduced.

Therefore, all the weight is extruded on the contact surface of the wheels and the ground, the rolling friction resistance moment of couple of the wheels and the ground is increased, the vehicle can move forwards only by increasing the driving force according to the vehicle-mounted weight, and the cost and the energy of the heavy vehicle are increased, so that the resource waste is caused.

The invention aims to provide a shock absorption and power assisting structure of a wheel type vehicle, which can provide driving power assistance and save energy.
One of the technical schemes for realizing the purpose of the invention is to provide a shock absorption and power assisting structure of a wheeled vehicle, which comprises wheels, a shock absorber, a shock absorption spring and a frame, wherein the shock absorption spring is sleeved on the shock absorber; the wheel hub of the wheel is connected with the shock absorber in a force transmission mode, the shock absorber is connected with the frame in a force transmission mode, the shock absorption spring and a vertical plane form an included angle alpha of 5-20 degrees, relative to the advancing direction of the wheel type vehicle, the shock absorber and the shock absorption spring are in a front-low and rear-high state, namely the shock absorber and the shock absorption spring are inclined backwards by 5-20 degrees in the advancing direction.
Further, the inclination angle α of the damper and the damper spring is 10 degrees.
Further, the rebound force generated by the shock absorption spring under the condition that the frame is pressed by the weight of the vehicle body is used as the assistance force to be added into the main power of the wheeled vehicle to drive the wheeled vehicle to move forwards together.
The second technical scheme for realizing the aim of the invention is to provide a shock absorption and power assisting structure of an automobile, which comprises wheels, a shock absorber, a shock absorption spring and a frame, wherein the shock absorption spring is sleeved on the shock absorber; the wheel hub of the wheel is connected with the shock absorber in a force transmission way, the shock absorber is connected with the frame in a force transmission way, the shock absorber and the shock absorption spring are components of the automobile suspension, and the suspension is connected with the frame;
the damping spring and the vertical plane have an included angle alpha of 5 to 20 degrees, and the shock absorber and the damping spring are in a front-low and rear-high state relative to the advancing direction of the automobile vehicle, namely the shock absorber and the damping spring have an inclination of 5 to 20 degrees backwards in the advancing direction.
Further, the inclination angle α of the damper and the damper spring is 10 degrees.
Further, the rebound force generated by the shock absorption spring under the condition that the frame is pressed by the weight of the automobile body is used as the assistance force to be added into the main power of the automobile to drive the automobile to run forwards together.
Further, the shock absorption helping hand structure of car still include hydraulic pump and hydraulic pump support, hydraulic pump support fixed mounting is in the corresponding wheel department in frame top, the hydraulic pump is installed on hydraulic pump support, the power take off end of hydraulic pump is connected with the upper end of bumper shock absorber, the inclination alpha of bumper shock absorber and damping spring is controlled through the concertina movement of the power take off end of hydraulic pump and different road conditions and the car condition of adaptation, the hydraulic pump of connecting in damping spring's upper end is used for adjusting the inclination of shake spring 3 when perhaps the vehicle parks to become 90 degrees vertical angle with ground.
The invention has the positive effects that: (1) the principle of the shock-absorbing and power-assisting structure of the wheeled vehicle is that according to Newton's third law, acting force between two objects is equal to reaction force, and similarly, the (active) acting force applied to the shock-absorbing spring is equal to the reaction force, but the directions of the two acting forces are opposite and act on the two objects respectively. When the vehicle is static, all the gravity of the vehicle body is on the vehicle frame, the vehicle frame bears all the vehicle-mounted gravity through the damping system, all the vehicle body weight is vertical to the ground, and the maximum value exists according to the static friction force, namely the maximum static friction force. Which is equal to the minimum external force required to move the object just before. The maximum static friction force is in direct proportion to the positive pressure of the contact surface, the maximum static friction force is increased along with the increase of the positive pressure and is reduced along with the reduction of the positive pressure. Therefore, the higher the weight of the automobile, the higher the static friction force of the automobile, the higher the cost in driving and the more energy is needed. Therefore, the auxiliary function of the rebound force (attack force) generated by the shock absorption spring under the condition of pressure can be utilized to help the main force of the vehicle to complete the task of driving the vehicle to move forwards by changing the installation angles of the shock absorption spring and the shock absorber, so that the energy is saved, and the emission of harmful carbon dioxide gas is reduced.
(2) The invention can change the reaction force of the damping spring into the boosting force by changing the design of the mounting angle alpha of the damping spring, so that the rebound force of the damping spring is reasonably applied, the burden of a damping mechanism of the damper is also reduced, and the great vehicle running cost is saved. The conventional design that the shock absorber is vertical to the ground is changed into the installation that the upper end of the shock absorption spring inclines towards the rear of the vehicle by an angle of 10 degrees, and then the reaction force direction of the shock absorber is changed. When the vehicle runs, the counterforce generated by the acting force of gravity on the shock absorber can act as the forward driving assistance for the vehicle. When the damping spring is installed perpendicular to the ground, the reaction force of the damping spring is released to vertically pressurize the ground, the damping spring can filter the vibration of the road surface, but the reaction force of the damping spring is difficult to release smoothly to generate jumping, and the damping structure of the damper is used for inhibiting the jumping of the damping spring. And the reaction force of the damping spring which is arranged at an angle of 10 degrees backwards inclined releases the resistance moment which hinders the rolling of the wheel, namely the rolling friction moment of the wheel, and the rebound force can make the rolling of the wheel more stable and play a role of assisting power. The burden of the damping mechanism of the shock absorber is reduced, and multiple benefits are achieved. The stopping device is opened to prevent the vehicle from sliding when the vehicle is parked, and the hydraulic pump is connected to the upper end of the damping spring to adjust the inclination angle alpha of the damping spring and return the damping spring to a 90-degree vertical angle with the ground when the vehicle is parked.
(3) The shock absorber is generally installed at an angle of 5-20 degrees inclined to the ground according to the self weight of the vehicle, the acting force of the vehicle weight on the shock absorbing spring is unchanged in the whole vehicle running process, and the assisting force of the counterforce on the vehicle is also unchanged. And the fluctuation of the running vehicle and the forward running inertia are reasonably applied, so that the method is a very good energy-saving scientific method. Therefore, the running cost can be saved, meanwhile, non-renewable resources are saved, the emission of toxic gas is reduced, and because the vehicle discharges a lot of incompletely burnt harmful gas in the starting and running processes, the design is applied to the shock absorption installation of bicycles, tricycles and automobiles, the function of assisting the running of the vehicle is played, and the wheel type vehicle can play a more perfect function.

Detailed Description
(example 1)
The working principle of the wheeled vehicle is as follows: for example, as shown in fig. 1, a two-wheeled bicycle has a rear wheel on the left side, a front wheel on the right side, and a forward direction from left to right, so that when people pedal the bicycle, a chain wheel rotates, and then a chain drives a flywheel of the rear wheel to rotate, so that the rear wheel rotates, and the bicycle rotates. The rear wheel is a driving wheel, and when the rear wheel moves under the drive of a chain or a gear, the rear wheel has a backward movement trend with a ground contact point, so that the rear wheel is subjected to a forward friction force. The rear wheel moves to push the front wheel to move forwards, so that the contact point of the front wheel and the ground has a forward movement trend, and the direction of the friction force is backward.
The back wheel is subjected to static friction force, and when the bicycle moves forwards, the wheel moves in a plane, and has translation and rotation, the translation speed is the same as the linear speed of each point of the edge when the bicycle rotates, the translation speed of the ground contact point moves forwards, and the rotation speed moves backwards. Therefore, according to the principle of motion synthesis, the resultant speed to the ground is zero, or the speed is zero because the contact point between the wheel and the ground is the instant center, that is, the wheel and the ground are kept relatively static. Its friction with the ground is static friction.
The factors that influence the static friction are: there is a maximum value of static friction, called the maximum static friction. Which is equal to the minimum external force required to move the object just before. The maximum static friction force is in direct proportion to the positive pressure of the contact surface, the maximum static friction force is increased along with the increase of the positive pressure and is reduced along with the reduction of the positive pressure. When the external force is increased to the moment that the object starts to move, the static friction force is increased to the maximum value, which is called the maximum static friction force. The maximum static friction force is related to the magnitude of the positive pressure, and is slightly greater than the sliding friction force.
Therefore, the static friction force is not a constant value, and the static friction force varies with the actual situation and is between zero and the maximum static friction force Fm. The value of which is determined by the external force to which the object is subjected at the time.
Rolling friction of the wheel with the ground: sometimes the wheels are "hard" and the support surface is "soft", the deformation of the support surface is essential, for example, the effect of a roller is to cause the mixture of asphalt and stone to undergo compression deformation to form a solid pavement; if the wheel is "soft" and the support surface is relatively hard, wheel deformation is dominant, such as rolling of an automobile wheel on a concrete road. Sometimes, both the wheel and the support surface are significantly deformed.
The wheel is placed stationary on a horizontal support surface and the deformation is symmetrical [ fig. 2 (a) ]. The horizontal support surface will deform slightly when the wheel is subjected to a (horizontal) force, so that the contact between the wheel and the horizontal plane is no longer a straight line through the contact point, but is slightly offset from a narrow curved surface in front of the rolling of the wheel, the horizontal counter-force of the constraint on the wheel is distributed over this narrow curved surface and is not symmetrical under the action of the force F [ fig. 2 (b) ]. This couple of resistance which resists the rolling of the wheel is the rolling friction couple moment of the wheel.
By the principle of the bicycle, the tire has a backward static friction force against the ground, and the ground also has a forward static friction force against the rear wheel. This force is the motive force for the vehicle to advance. Since the wheels roll on the ground, rolling friction force is always generated, and only rolling friction is left for the reason that the bicycle is difficult to ride without air. When the bicycle wheel is pressed on the ground, elastic deformation must occur, the ground also deforms, but the deformation of the wheel is main. When the bicycle is inflated, the deformation of the wheels is increased, so that the protruding parts at the front parts of the wheels are more convex, the rolling friction torque is increased, and the bicycle is difficult to ride.
The factors influencing the rolling friction force are that the rolling condition of the object is related to the contact surface, and when the rolling object rolls on the contact surface or has a rolling tendency, the object and the contact surface are deformed.
The deformation can be divided into four conditions that the contact surface is deformed, the rolling object is not deformed (the object is called a rigid body at the moment), the contact surface is not deformed (the contact surface is called a rigid surface at the moment), the rolling object is deformed, the contact surface and the rolling object are not deformed, the contact surface and the rolling object are both deformed, and the like. When the tyre of the bicycle runs on a cement road, the problems that the contact surface is rigid and the rolling object deforms can be simplified.
Referring to fig. 5, the shock absorption assisting structure of the wheeled vehicle of the present embodiment includes a wheel 1, a shock absorber 2, a shock absorption spring 3 and a frame 4, the shock absorption spring 3 is sleeved on the shock absorber 2 and axially limited by a spring seat of the shock absorber 2 to form a shock absorption member, and the shock absorber 2 is used for suppressing shock and impact from a road surface when the shock absorption spring 3 rebounds after absorbing shock; when the wheel type vehicle is a two-wheeled vehicle such as a bicycle or a motorcycle, the shock absorber 2 is connected with the shock-absorbing front fork or the shock-absorbing rear fork or directly is a part of the shock-absorbing front fork or the shock-absorbing rear fork, and the shock-absorbing front fork or the shock-absorbing rear fork is connected with the frame 4; when the wheeled vehicle is a four-wheel vehicle such as an automobile and the like and a similar wheeled vehicle having a suspension system, a hub of a wheel 1 is connected to a corresponding suspension, and a damper 2 and a damper spring 3 are main components of the automobile suspension, and the suspension is connected to a frame 4. Wherein the damper spring 3 has an angle of 5 to 20 degrees with the vertical plane, and the damper 2 and the damper spring 3 are low in front and high in back relative to the advancing direction of the wheeled vehicle, i.e. the damper 2 and the damper spring 3 have an inclination of 5 to 20 degrees in back in the advancing direction, and the angle α is preferably 10 degrees. The principle is that according to newton's third law, the action force between two objects is equal to the reaction force, and the (active) action force applied to the damper spring 3 is equal to the reaction force in the same way, but their directions are opposite and act on the two objects, respectively. When the vehicle is at rest, all the gravity of the vehicle body is on the vehicle frame 4, the vehicle frame 4 bears all the vehicle-mounted gravity through a damping system, all the vehicle body weight is vertical to the ground, and the maximum value exists according to the static friction force, namely the maximum static friction force. Which is equal to the minimum external force required to move the object just before. The maximum static friction force is in direct proportion to the positive pressure of the contact surface, the maximum static friction force is increased along with the increase of the positive pressure and is reduced along with the reduction of the positive pressure. Therefore, the higher the weight of the automobile, the higher the static friction force of the automobile, the higher the cost in driving and the more energy is needed. Therefore, the main power of the vehicle can be assisted by the boosting function of the rebounding force (attack force) generated by the damping spring 3 under the condition of pressure through changing the installation angle alpha of the damping spring 3 and the damper 2, so that the vehicle can be driven to run forwards, and the emission of harmful carbon dioxide gas is reduced while the energy is saved.
In the embodiment, the design of changing the installation angle alpha of the damping spring 3 changes the reaction force of the damping spring 3 into the boosting force, so that the rebound force of the damping spring 3 is reasonably applied, the burden of a vehicle damping mechanism is reduced, and the great vehicle running cost is saved. The conventional design that the damping spring 3 is vertical to the ground is changed into the installation that the upper end of the damping spring 3 inclines towards the rear of the vehicle by an angle of 10 degrees, and then the reaction force direction of the damping spring 3 is changed. When the vehicle runs, the reaction force generated by the damping action force can be used for assisting the vehicle to move forwards. Since the reaction force of the damper spring 3 is released to be vertically pressurized with respect to the ground when the damper spring 3 is installed vertically to the ground, the damper spring 3 can filter the vibration of the road surface, but the reaction force of the damper spring 3 is difficult to be smoothly released to generate a jump, and the damper 2 is constructed to suppress the jump of the damper spring 3. And the reaction force of the damping spring 3 which is arranged at an angle of 15 degrees and inclines backwards releases the resistance moment of couple which hinders the rolling of the wheel 1, namely the rolling friction moment of couple of the wheel 1, and the reaction force can make the rolling of the wheel 1 smoother and play the role of boosting. Meanwhile, the reaction force can be changed into the assistance force to be smoothly released, and the burden of the vehicle damping mechanism plays a role in multiple benefits. The stopping device is opened to prevent the vehicle from sliding when the vehicle is parked, and the hydraulic pump is connected to the upper end of the damping spring 3 to adjust the inclination angle alpha of the damping spring 3 and to restore the damping spring 3 to a 90-degree vertical angle with the ground when the vehicle is parked.
The shock absorber 2 and the shock absorbing spring 3 are installed in a side-inclined mode by 15 degrees, according to the Newton's law, the vehicle-mounted weight applies force to the shock absorbing spring 3 and simultaneously generates equal reaction force, the direction of the force is opposite to that of the active force, and the force is applied to two different objects respectively. At this time, the vehicle body gravity applies a force to the damper spring 3, and a reaction force is transmitted to the wheel 1 to be a forward assisting force. Since the force makes a straight-line motion at a constant velocity, the release direction of the reaction force of the inclination of the damper spring 3 is in front of and below the wheel 1 according to newton's first law: the force and reaction force should be collinear.
As shown in fig. 3 (a), the damping spring 3 is installed at a vertical angle with the ground, and the reaction force is released at point B, increasing the pressure of the wheel on the ground, and increasing the friction force increases the running cost. If the damping spring 3 is installed at an angle of 15 degrees to the ground, the reaction force is released at B1, which is the point after the wheel 1 is subjected to a horizontal force, such as: fig. 2 (b) the resultant of these distributed forces, for example, no longer acts on the contact point but rather acts at a point in front of the rolling of the wheel 1, at which point the resultant of these distributed forces and the force of gravity form a couple, which is the couple that hinders the rolling of the wheel 1, and which is the couple moment of the rolling friction of the wheel 1. Releasing the reaction force at this point will counteract the rolling friction couple moment and act as a boost. That is, the acting force of the vehicle weight on the damping spring 3 is not changed during the whole vehicle running process, and the assisting force of the counterforce on the vehicle is also not changed. And the fluctuation of the running vehicle and the forward running inertia are reasonably applied, so that the method is a very good energy-saving scientific method. Therefore, the running cost can be saved, non-renewable resources are saved, the emission of toxic gas is reduced, and the discharge of harmful gas which is not completely combusted in the starting and running processes of the vehicle is large, so that the design is applied to the shock absorption installation of bicycles, tricycles and automobiles, the function of assisting the riding is achieved, and the bicycle riding can be very easily turned into the greenest vehicle. According to different vehicle types, the installation angle alpha of the damping spring 3 can be 5 degrees to 20 degrees, the most reasonable angle is selected, safety is the primary consideration in the selection of the angle, the experiment is carried out by selecting 10 degrees, because the linear release point of the reaction force of 10 degrees is at the position where the rolling friction moment of couple is generally the largest on the wheel, the boosting effect is better and safer, and the boosting function and efficacy of the damping spring 3 at the installation angle are 20% to 30% under the horizontal condition according to the road.
