The utility model provides it controls stability, ride comfort, security and travelling comfort to have risen cycle racing, the utility model discloses still has simple structure, reliable and stable advantage.
Description
Technical field
This utility model relates to a kind of double transverse arm step type semi-active suspension system.
Background technology
Suspension system is one of most important ingredient in university students's equation motorcycle race, plays buffering road surface exciting, decay vibration, supports the effect of vehicle body and transmission power and moment, it is ensured that the comfortableness of occupant.
The performance extreme influence of suspension system control stability and the ride comfort of racing car, thus also determine the safety of racing car, the fast state that suspension system racing car to be met is required when travelling, the racing car to be adapted to extremity under anxious acceleration, anxious deceleration and high lateral acceleration, if value is improper, the performance of racing car will be had a greatly reduced quality, and potential safety hazard even occurs.
Now the competition racing car overwhelming majority uses double cross arm independent suspension, and the suspension advantage of the type is that wheel clears the jumps when beating, and the change of every basic parameter is little, such as wheelspan, camber angle, kingpin inclination and toe-in etc..On the other hand, when racing car is turned, either stand big lateral acceleration or little lateral acceleration, vehicle body and suspension system can be maintained at stable state all the time, do not have praise, situation that lateral deviation is excessive.Simultaneously as its simple in construction, it is easy to manufacture assembling, manufacturing cost can be reduced and promote work efficiency.
But, present racing car nearly all uses passive suspension, and no matter which kind of state racing car is under, and its parameter value is fixing, and this makes the performance of racing car not bring into play completely, also have impact on the comfortableness of racing car.Therefore, it is necessary to suspension system is improved, promote the performance of racing car further.
Summary of the invention
In order to solve above-mentioned technical problem, this utility model provides double transverse arm step type semi-active suspension systems that a kind of simple in construction, convenient maintenance and stability are high.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of double transverse arm step type semi-active suspension system, including two wheel rims, two rocking arms and two vibroshocks；Wheel rim passes through column one end respectively with force-guided stem, Top Crossbeam and lower cross arm and is connected；The other end of Top Crossbeam and lower cross arm is fixed on vehicle frame, and the other end of force-guided stem is hinged with rocking arm；Rocking arm is hinged on vehicle frame, and rocking arm is connected with one end of vibroshock, and the other end of vibroshock is hinged on vehicle frame；Described vibroshock is piston, is provided with spring between hydraulic cylinder and the piston rod of piston.
In above-mentioned double transverse arm step type semi-active suspension systems, being provided with bypass line between described hydraulic cylinder two ends, bypass line is provided with bypass valve.
Compared with prior art institute, the beneficial effects of the utility model:
(I) this utility model only carries out little improvement, simple in construction to vibroshock, and the requirement for cost, equipment and material is less, it is easy to maintenance；
(II) this utility model is without power source, the most controlled damping element, reduces energy loss；
(III) this utility model utilizes the damping value of the open and-shut mode regulation vibroshock controlling bypass valve, control stability and the ride comfort of racing car can be substantially improved, and then promote comfortableness and the safety of racing car；
(IV), for comparing passive suspension, improve degree little, but performance boost is higher, for comparing Active suspension, does not consume vehicle power, can obtain again the performance close with Active suspension, therefore have preferable application prospect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing of damper portion during bypass valve of the present utility model unlatching.
Fig. 3 is the enlarged drawing of damper portion during bypass valve of the present utility model closedown.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
As Figure 1-3, this utility model includes 1, two rocking arms 3 of two wheel rims and two vibroshocks 5；Wheel rim 1 passes through column one end respectively with force-guided stem 2, Top Crossbeam 6 and lower cross arm 8 and is connected；The other end of Top Crossbeam 6 and lower cross arm 8 is fixed on vehicle frame by auricle 7 respectively, and the other end of force-guided stem 2 is hinged with rocking arm 3；Rocking arm 3 is hinged on vehicle frame, and rocking arm 3 is connected with one end of vibroshock 5, and the other end of vibroshock 5 is hinged on vehicle frame.Described amortisseur 5 is piston, is provided with spring 4 between hydraulic cylinder 10 and the piston rod of piston.Being provided with bypass line 9 between the hydraulic cylinder two ends of described vibroshock 5, bypass line 9 is provided with bypass valve.Utilize the damping value of the open and-shut mode regulation vibroshock controlling bypass valve, control stability and the ride comfort of racing car are substantially improved, and then promote comfortableness and the safety of racing car.
Jumping can be gone up when wheel is by road surface exciting, vibration is transferred to column by wheel rim 1 of the present utility model, being transferred to force-guided stem 2 and Top Crossbeam 6 and lower cross arm 8 from column again, the compression spring 4 on rocking arm 3 rear shock absorber 5 through having a stable drive ratio also forces shock absorber 5 to work.
If as in figure 2 it is shown, now excited frequency and vehicle body natural frequency ratio have exceeded 1.4, bypass valve 9 should be opened, make fluid can flow at hydraulic cylinder 10 two ends through bypass valve 9, reduce damping with this.
If as it is shown on figure 3, now excited frequency and vehicle body natural frequency ratio are less than 1 and time ratio is less, bypass valve 9 should be closed, makes fluid can not flow in hydraulic cylinder 10 through bypass valve 9, increase damping with this.
