Under normal conditions, the weight of trapezoidal brake block 4 is 3-5 times of vehicle weight.As shown in Figure 3,4, each pendulum consumption
Energy mechanism includes the curve up ball face block 5.1 being connected with brake block 4 and the curve down ball face block 5.2 being connected with road bed, upper song
Middle curve face block 5.3, middle curve face block 5.3 and curve up ball face block 5.1 are provided between spherical surface block 5.1 and curve down ball face block 5.2
It is respectively constituted on the lower convex globoidal B that the upper convex globoidal A and middle curve face block 5.3 matched is matched with curve down ball face block 5.2
Be slidably matched, and upper convex globoidal A and lower convex globoidal B with the center line symmetrical setting of middle curve face block 5.3 (its specific size with
Subject to the actual needs of upper deformation), so that curve up ball face block 5.1 and middle curve face block 5.3 is entered the feelings of braking casting bed 2 in vehicle
Under condition, horizontal reciprocating swing is done in X direction on curve down ball face block 5.2, so that vehicle energy be made to consume before the deadline
It finishes.The own slip for passing through pendulum energy consuming mechanism 5 realizes reciprocally swinging, quickly consumes energy.Pendulum energy-consuming device is two-way
Sliding, both can satisfy the malformation under normal operating condition, moreover it is possible to guarantee sliding energy consumption when vehicle drives into.
In order to monitor the swing speed of curve up ball face block 5.1 and middle curve face block 5.3, in one or more pendulums energy consumption machine
Installation speed sensor 6 on structure 5, and velocity sensor 6 with lead the way on 1 multiple are set anti-withdraw device 3 and be connected.As Fig. 5,
Shown in 6, the anti-device 3 that withdraws is located at braking 2 downstream of casting bed, each anti-to withdraw device 3 and include the protective case for being embedded in and leading the way in 1
The bottom of cylinder 3.1, protection sleeve 3.1 is equipped with electromagnet 3.2, protects in sleeve 3.1 and is equipped with Pop-up lever 3.4, pops up
It is provided with the compressed spring 3.3 being connected with protection 3.1 bottom wall of sleeve below formula lever 3.4, is provided with above Pop-up lever 3.4
It is hinged on the baffle 3.5 of protection 3.1 opening of sleeve, the main function of lever 3.5 is the Pop-up lever 3.4 inside protection,
The pop-up of lever 3.4 is not stopped.Velocity sensor 6 is using conventional photo-electric vehicle speed sensor, the double ± 1.7g of range, highest
Resolution ratio 0.83mg, signal output end are electrically connected with the signal input part of single-chip microcontroller, the control signal of single-chip microcontroller with it is described
The anti-control signal electrical connection for withdrawing electromagnet 3.2 in device 3.Under normal circumstances, lever 3.5 is covered on Pop-up lever
3.4 top, be located at protection sleeve 3.1 in, do not influence vehicle normal through；When velocity sensor 6 detects curve up ball face
When the swing speed of block 5.1 and middle curve face block 5.3 is excessive, needs to stop vehicle, prevents it from recalling main road, at this point,
Single-chip microcontroller issues signal to electromagnet 3.2, discharges the constraint to automatically controlled lever 3.4, Pop-up lever 3.4 is in compressed spring 3.3
Under the action of be ejected into 1 road surface of leading the way or more, play the role of anti-withdraw.The above-mentioned anti-device 3 that withdraws is with specific aim and automatic knowledge
Other property, under normal use conditions, the deformation of pendulum energy consuming mechanism 5 and low-speed motion as caused by the reasons such as temperature shrinkage,
The anti-device 3 that withdraws will not be triggered to work.In order to facilitate later period rescue, rescue lane N is additionally provided in the side of braking casting bed 2.
Under normal circumstances, hedging vehicle first along inclination lead the way 1 upwards traveling, reduce speed now under Gravitative Loads, when
After vehicle continues in traveling arrival braking casting bed 2, since the material friction coefficient in braking casting bed 2 is higher, the kinetic energy of vehicle
Brake block 4 is passed to by braking casting bed 2, according to impulse principle, since brake block 4 has biggish weight relative to vehicle,
Therefore, speed is substantially reduced after vehicle and brake block 4 combine；Then vehicle, braking casting bed 2 and brake block 4 are together to advancing slip
Dynamic, mass action is on pendulum energy consuming mechanism 5.The curve down ball face block 5.2 and road bed of pendulum energy consuming mechanism 5 consolidate, upper song
The top of spherical surface block 5.1 and brake block 4 consolidate, therefore, the effect of curve up ball face block 5.1 and middle curve face block 5.3 in brake block 4
Under, it is slid back and forth horizontally along the X direction on curve down ball face block 5.2, and the pendulum of curve up ball face block 5.1 and middle curve face block 5.3
Dynamic direction is consistent with the direction of vehicle active force that brake block 4 is subject to.When speed is larger, can be sent out between brake block 4 and vehicle
Relative displacement is given birth to, can also generate frictional force between the two contact surface.Due to 5 reciprocally swinging of pendulum energy consuming mechanism, vehicle phase
The distance that contact surface is run over is increased, vehicle energy consumption is accelerated, this process can continue to that vehicle stops completely.When vehicle speed
When spending height, the swing speed of pendulum energy consuming mechanism 5 being caused to reach preset value, velocity sensor 6 sends a signal to single-chip microcontroller, single
Piece machine control electromagnet 3.2 release constraint attraction, make Pop-up lever 3.4 be ejected into 1 road surface of leading the way or more prevent vehicle because
It is withdrawn from recurrence, guarantees vehicle and the safety of related personnel.
The braking process of above-mentioned hedging vehicle can be stated by the correlation formula of series matter Neo-Confucianism:
The weight of hedging vehicle is calculated as M, when travelling on ramp, gravity does negative work, and car speed, which has begun, to be subtracted
It is small；Assuming that speed is V when driving into braking casting bed, the momentum of brake block weight m=5M, automobile pass to the brake block of lower part, hedging
Vehicle and brake block integrally become superstructure, and by the frictional force of casting bed, vehicle drives the system that connects with casting bed lower part of casting bed
Motion block m is moved together, and the speed of automobile is reduced to, the speed of brake block becomes。
According to the law of conservation of momentum, the movement velocity prediction equation of vehicle and brake block are as follows:
According to principle of conservation of energy:
Travel speed before relatively, car speed viaIt is reduced to.Later, vehicle continues to move ahead, gravity and frictional force
Brake force is provided simultaneously, according to conservation of energy principle, the energy of vehicle is all offset by gravity and friction working, i.e.,
By above formula as can be seen that vehicle energy is a definite value, gravity acting is related with the height H of vehicle driving and one
A definite value, it is determining for being left frictional force work done, it is meant thatIt is a determining value, i other words vehicle and contact surface
Opposite operating range will not change.
As it can be seen that the present invention passes through the reciprocally swinging of pendulum energy consuming mechanism, so that vehicle and contact according to above-mentioned braking principle
Rubbing number between face increases, interior at the same time, and the opposite distance that vehicle driving is crossed increases, and accelerates the energy of vehicle
Consumption.That is, reducing absolute movement distance of the vehicle with respect to ground by setting pendulum energy consuming mechanism, that is, reducing
Braking distance.Meanwhile when speed is higher, the swing speed of pendulum energy consuming mechanism is too fast, it is associated with it is anti-withdraw device can
Automatic work sufficiently avoids vehicle from causing safety accident on main stem because gravity is withdrawn.
