The mode of this power transmission, in the middle of the automobile of manual retaining (MT), mainly the degree of engagement by artificial solenoidoperated cluthes realizes that this way has improved the amount of labour of driver in the process that drives a car; In electronic control manual (AMT), because electronically controlled stability, technically all be not so good as outstanding driver, and increased microcomputer system, shift impact is strong, starting is slow, the more high shortcoming of cost so exist.

In automatic catch (AT), then use torque converter to realize functions such as step gear shifting, torque converter be a kind of Fluid coupling it can allow engine and gearbox separately independently the rotation.If automobile is waiting the red light engine idle, the rotating speed of engine is very low, and the torsion of its input torque transducer is just very little.So just can allow automobile keep static as long as gently apply the brakes.Though this way need not manually to control the degree of clutch with respect to manual clutch, advantage be simple to operate, travelling comfort good; But,, also exist the cost height, safeguard that complicated, starting speed waits shortcoming slowly so that shortcoming is a fuel efficiency is not high, meanwhile because Fluid coupling exists the loss of energy.

The power transmission buffer does not need on the one hand the combination degree of driver's solenoidoperated cluthes in the starting of automobile, shift process, can not cause a large amount of losses of automobile power output on the other hand yet, is a kind of not only convenient but also economic power transmission damping device.

Summary of the invention

This device reduces driver's operation for clutch in vehicle starting, shift process by the mechanical device transformation, and realizes the economy output of power simultaneously.

The solution that this device is taked is: a kind of power transmission buffer, comprise input shaft, output shaft, flywheel, platen, the roller of exerting pressure, the roller bearing of exerting pressure, gas pedal, transmission axle, release bearing and can twist damping device, wherein transmission axle and output shaft around roller bearing is set, transmission axle and output shaft all can rotatablely move on roller bearing, connect with twisting damping device between the two, the joint of gas pedal control flywheel and platen with separate.Can twist damping device is high pulling torque spring or clockwork spring.

Between transmission axle and the output shaft, fix, so that can relative displacement not take place between the two because of the distortion pressure that can twist damping device with a hard coat.During engine power output, power transmission is to flying disc, transfer to transmission axle by hard connection then, can twist the damping device connection because use between transmission axle and the output shaft, when so power transmits between transmission axle and output shaft, can produce a speed difference because twisting the effect of damping device, thereby make motor obtain a resistance that changes from small to large, give output shaft a power output from small to large simultaneously, this output finally transfers to automobile tire by other devices, make automobile can realize gentle start on the one hand, make motor be unlikely to stop working on the other hand because of unexpected resistance.

The birth of this device means that automobile controls an important advance of aspect, by add this device in automobile, can substitute the clutch function in part even the whole existing automobile, has advantages such as cheap, simple to operate, that wearing and tearing are small.In manual automobile, the automobile that adds this device is when starting, gearshift, need not to re-use clutch and carry out the clutch operation, saved driver's the complexity of controlling greatly, meanwhile, because automobile clutch is product easy to wear, and this device has advantages of cheap price, the automobile that installs this device additional can reduce the user cost in the future of automobile; In automatic catch automobile, this installation cost significantly reduces, and the automobile that adds this device simultaneously is because in the process of power transmission, and power loss is little, therefore the hydraulic power transmission means of taking with respect to existing automatic catch automobile is saved energy, can reach the purpose of fuel-economizing.

Description of drawings
